Tooltip= Why this environmental topic is important to Planning

Active Transportation

The Active Transportation topic describes a range of programs, policies, case studies and other resources related to the role of transportation in support of livable and sustainable communities, including multimodal transportation options that advance public health goals. Transportation planning is an important aspect of meeting these goals.

Active Transportation
Air Quality

Transportation planners address air quality issues on the regional scale and project scale. Regional-scale analyses estimate how regional transportation plan and transportation improvement program implementation affect region-wide emissions. During the transportation conformity process, regional-scale emissions are compared to allowable levels, or "budgets." Project-scale analyses involve "hot spot" assessments focused on whether pollutant concentrations near roads exceed standards or how projects affect emissions.

Air Quality
Climate Change Mitigation/Adaptation

Climate Change Mitigation/Adaptation covers two complex, and distinct sub-topics: Energy/Greenhouse Gas Emissions and Infrastructure Resilience.

Climate Change Mitigation/Adaptation
Energy/Greenhouse Gas Emissions

Consideration of energy and greenhouse gas emissions is an important part of the transportation planning process. Planning processes can help transportation decision-makers determine approaches to reduce transportation energy use, decrease emissions, and achieve related benefits.

Energy/Greenhouse Gas Emissions
Infrastructure Resilience

Transportation planning plays a key role in addressing potential impacts from extreme events and changing climate conditions and building resilience into the transportation system.

Infrastructure Resilience
Context Sensitive Solutions

Context Sensitive Solutions (CSS) is a collaborative, interdisciplinary, holistic approach to the development of transportation projects. It involves careful consideration of community values, environmental features, land use, transportation function and available budget. CSS can be incorporated into all phases of program delivery including long range planning.

Context Sensitive Solutions
Environmental Justice

Title VI of the Civil Rights Act and environmental justice principles apply to all U.S. DOT activities. Transportation agencies must ensure that State Transportation Improvement Program findings of statewide planning compliance and NEPA activities satisfy Title VI requirements and environmental justice principles, ensure the meaningful participation of minority and low-income populations, and create systems and projects that can improve the environment for low-income and minority communities.

Environmental Justice
Environmental Management Systems

An environmental management system is the organizational structure and associated processes for integrating environmental considerations into the decision-making processes and operations of an organization. An EMS can ensure environmental considerations are taken into account during transportation planning.

Environmental Management Systems

This topic covers project delivery and environmental provisions of both the FAST Act and the MAP-21 surface transportation funding and policy legislation. The legislation may affect all aspects of transportation projects including planning, design, construction, and maintenance. It includes language on linking planning and NEPA processes.

Geographic Information Systems

Use of GIS is one of several tools to show past, current, or predicted future conditions of the natural and built environment during transportation planning phases. GIS is used to enhance the transportation planning by providing a tool to share information in an easily understood format to better inform decision making.

Geographic Information Systems
Historic Preservation/Cultural Resources

Transportation agencies must address historic preservation and cultural resource issues during the transportation project planning and development processes under Section 106 of the National Historic Preservation Act and Section 4(f) of the Department of Transportation Act. Early identification of resources in planning can expedite project delivery and provide opportunities for context sensitive solutions.

Historic Preservation/Cultural Resources
Indirect Effects/Cumulative Impacts

Transportation agencies analyze indirect effects and cumulative impacts as part of the NEPA environmental review process. These analyses include consultation with stakeholders and the public, identification of important trends and issues, and analysis of the potential for land use change and related environmental impacts on valued and vulnerable resources. The long-range planning process helps identify the future system to be evaluated for cumulative impacts in the NEPA process.

Indirect Effects/Cumulative Impacts
Invasive Species/Vegetation Management

Transportation agencies are increasingly linking transportation and conservation by adopting best management practices, including roadside vegetation management plans. One of the keys to successful roadside vegetation management is treating the roadside when the highway is first built or when improvement projects are planned, designed and constructed.

Invasive Species/Vegetation Management
NEPA Process

The first stage of the NEPA process—development of project purpose and need—builds upon the transportation needs identified during planning and will be the basis for the final selection of a project alternative. A project also must be included in a conforming plan and TIP before it can be advanced. Agencies can benefit by incorporating environmental and community values into transportation decisions early in planning and carrying these considerations through project development and delivery.

NEPA Process

FHWA requires consideration of mitigation for highway traffic noise in the planning and design of Federally aided highways.

Planning & Environment Linkages

This topic covers efforts such as FHWA’s Planning and Environment Linkages (PEL), a collaborative and integrated approach to transportation decision-making that considers environmental, community, and economic goals early in the transportation planning process, and uses the products developed during planning to inform the environmental review process. Related efforts include Eco-Logical, an ecosystem-based approach to transportation planning and infrastructure development.

Planning & Environment Linkages
Project Delivery/Streamlining

Streamlined project delivery can be achieved through efforts to link transportation planning and the NEPA process. Agencies can benefit by incorporating environmental and community values into transportation decisions early in planning and carrying these considerations through project development and delivery.

Project Delivery/Streamlining
Section 4(f)/Section 6(f)

Section 4(f) of the Department of Transportation Act established the requirement for consideration of park and recreational lands, wildlife and waterfowl refuges, and historic sites in transportation project development. DOTs must conduct all possible planning to minimize a project’s harm to a Section 4(f) resource. Agencies also must meet requirements under Section 6(f) of the Land and Water Conservation Fund Act regarding conversion of land to non-recreational use.

Section 4(f)/Section 6(f)

Sustainability refers to taking into account social, environmental and economic considerations in transportation. These principles are important in all aspects of transportation, including long-range planning. The principles can then be carried through to short-range planning and program/project development.

Waste Management/Recycling/Brownfields

Transportation activities, from project planning and development through operations and maintenance, are affected by a variety of requirements and initiatives related to the management, disposal, and recycling of wastes. Transportation is also an important aspect in redevelopment of brownfield properties.

Waste Management/Recycling/Brownfields
Water Quality/Wetlands

Protecting water quality is an ongoing environmental concern for transportation agencies, including requirements for stormwater runoff and mitigation of impacts to wetlands and water resources. Potential impacts to water quality, including advance mitigation and stormwater management, can be addressed during the planning process.

Water Quality/Wetlands
Wildlife & Ecosystems

Planning considerations are important in addressing potential impacts of transportation to wildlife and ecosystems. Efforts such as FHWA’s Planning and Environment Linkages offer an ecosystem-based approach to infrastructure planning. Practices to address impacts to wildlife include crossing structures, reestablishing habitat connectivity through land use, and programmatic agreements for species protection.

Recent Developments: Report Assesses Transit Decline in Southern California

Per capita transit trips have been declining in the six counties that comprise the Southern California Association of Governments, according to a new report by the group. The report indicates that feeling unsafe on transit vehicles, the decrease in fuel prices, and the rise of transportation network companies such as Lyft and Uber could be contributing factors to the fall in ridership. The report also suggests that an increase in private vehicle access and the replacement of transit users with people more likely to drive also may be causes for such a decline. In contrast, service quantity and reliability are not considered to play a part in transit decline because ridership was falling even on routes with excellent on-time records, according to the report. The report recommends that transit agencies seek to convince those who rarely use transit to begin riding occasionally. The study examined transit in Imperial, Los Angeles, Orange, Riverside, San Bernardino, and Ventura counties. For more information, link to the report. (2-2-18)

Recent Developments: Study Finds Milwaukee Residents Have Unequal Access to Biking, Walking Facilities

The Rails-to-Trails Conservancy has issued a report finding that neighborhoods in Milwaukee that experience social or economic inequality have a disproportionate lack of access to multimodal facilities. Specifically, in certain parts of the city only 3 percent of residents are within walking distance of a trail and 8 percent are within biking distance of a trail. These areas are predominantly African-American or Hispanic neighborhoods and have higher concentrations of poverty, unemployment and zero-car households. The study used RTC’s “BikeAble” tool, a GIS-modeling platform that analyzes connectivity to determine the best low-stress routes for bicycling. Low-stress routes are ones with speed limits below 25 miles per hour and which lack significant physical barriers to safe crossing for bicyclists or pedestrians.

Case Studies: Hawaii - Hawaii DOT Promotes Benefits of Walking with Nation's First Pedestrian Master Plan

A new focus on pedestrian safety and the benefits of walking can be seen throughout Hawaii thanks to the nation’s first Statewide Pedestrian Master Plan adopted by the Hawaii Department of Transportation.

Released in May 2013, the Hawaii Statewide Pedestrian Master Plan was developed to improve pedestrian safety, mobility, and connectivity. At the same time, the plan sought to promote the benefits of walking – including a healthier environment, healthier citizens, and a stronger economy.

The plan provides a formalized process to assess the needs of pedestrians, develop and prioritize projects, and provide an implementation strategy, according to Rachel Roper, the project manager for the plan and a civil engineer with the HDOT Highways Division Planning Branch.

The plan identifies ways to improve pedestrian safety and mobility through engineering, education, and enforcement. It prioritizes 31 pedestrian infrastructure projects, advances the state’s complete streets policy, and fulfills federal multimodal planning requirements.

A key component of the plan is the Hawaii Pedestrian Toolbox, a companion document containing best practices for planning, design, operation, and maintenance of pedestrian facilities.

To ensure effective implementation, the plan also describes potential funding strategies and provides performance measures for monitoring progress. The performance measures reflect specific objectives and methods to achieve the following goals of the plan:

  • improve pedestrian mobility and accessibility;
  • improve pedestrian safety;
  • improve connectivity of the pedestrian network;
  • promote environmental benefits of walking;
  • encourage walking to foster healthy lifestyles;
  • enhance communities and economic development by creating pedestrian-oriented areas and positive pedestrian experiences; and
  • promote and support walking as an important transportation mode that reduces overall energy use.

Examples of the pedestrian projects HDOT is advancing include implementing Walk Wise Hawaii, a program to educate communities about pedestrian and driver awareness; replacing traditional traffic signals with countdown timers; and installing sidewalks to improve connectivity.

The American Planning Association recognized Hawaii’s pedestrian plan with its 2014 National Planning Award for Excellence in Transportation Planning, citing the plan for being the first in the nation with a statewide, pedestrian-only focus and for being transferable to other states.

HDOT’s efforts in engaging the public and identifying priority areas of concern also were featured as noteworthy practices in the Federal Highway Administration’s Statewide Pedestrian and Bicycle Planning Handbook, released in September 2014.

Developing the Plan

HDOT sought to develop a pedestrian-focused plan to fulfill a goal of reducing traffic-related deaths in Hawaii’s Strategic Highway Safety Plan, 2007-2012. Hawaii had the fifth highest pedestrian fatality rate nationwide due to traffic-related crashes from 2001-2005, with 22 percent of traffic crashes statewide involving pedestrians.

The agency structured the plan development process to balance technical expertise from HDOT’s Highway Design and Traffic Operations Sections with extensive involvement from the public, Roper said. HDOT established two stakeholder committees: a Technical Advisory Committee and a Citizens Advisory Committee. The technical group was comprised of staff from federal, state, and city and county agencies. The citizens committee represented diverse public interests, such as neighborhood organizations, seniors, students, local businesses, and minority and disadvantaged populations. HDOT also held a series of public meetings and workshops and maintained a project website throughout the plan development process.

The project team identified “areas of concern” for recommended pedestrian improvements through a geographic information system analysis of existing conditions statewide. This was combined with input from the stakeholder committees and the public. Criteria to evaluate the areas of concern and to prioritize recommended solutions were developed based on the key factors of pedestrian connectivity, accessibility, pedestrian-oriented populations, and safety. The criteria were reviewed by the two advisory groups and validated through public meetings.

The project team then applied best practices in pedestrian-oriented design from the companion Hawaii Pedestrian Toolbox to evaluate potential solutions in the areas of engineering, education, and enforcement. The process – which included sharing potential solutions with the citizens’ advisory committee and the public – resulted in a prioritized list of 31 recommended pedestrian projects and programs.

Lessons Learned

HDOT invested a lot of time with stakeholder groups to develop a comprehensive set of goals, objectives, and recommendations addressing all the facets of pedestrian issues, Roper said.

While the extensive process of public and stakeholder involvement was immensely valuable, it was also challenging and added a lot of time to the plan development process,” Roper said. This is something that other state DOTs should consider when developing a project schedule or contract.

Roper also emphasized that it’s important to approach the process holistically, including both technical and nontechnical staff as well as internal and external stakeholders. “It can’t be thought of separately and then just mushed together at the end,” she said.

Having an established process for decision-making and sharing of information between the project team and stakeholders at the start of the process also was key, Roper said. HDOT was doing extensive outreach, and there was a lot of interest in the project from the public, community groups, the media, and others.

“A lot of people wanted to provide input and wanted to see it in the plan, but some were afraid that all the input we received would go into a ‘black box’ somewhere and get lost,” according to Roper. “It was important to ensure that accurate and consistent information was being disseminated” so everyone involved could see how information was used in the plan.

The process also featured a two-way information flow between the project committees and stakeholder groups throughout, Roper said. Members of the technical committee attended public meetings, as did HDOT leadership, when possible.

Other challenges included scheduling meetings with stakeholders who have busy schedules; collecting and responding to the many comments; and balancing the wide variety of opinions.

Ultimately, HDOT wanted the plan to be implemented by its staff and not to “just sit on the shelf,” Roper said. The agency conducted internal roll-out sessions to make sure staff needs were addressed and that “everyone involved in the project delivery process, including planning, design, construction, operations, and maintenance, was aware of the plan and felt it was feasible and implementable.” In the end, this extensive and transparent public involvement process succeeded in generating a lot of support for the plan, both within HDOT and externally, and was a key contributor to the success of the plan and its implementation, Roper said.

Case Studies: Utah - Utah DOT Program Provides Support, Recognition for Community Bicycle Programs

The Utah Department of Transportation (UDOT) is building support for bicycling programs across the state through a grass-roots program to help communities with bicycle planning and promoting active transportation.

The Road Respect Community program provides local governments with guidance in planning and developing their bicycle programs and infrastructure. The program also provides recognition, allowing localities to earn the “Road Respect Community” title for their efforts to encourage active transportation.

The program is an offshoot of the Road Respect bike safety education campaign, launched in 2011 by UDOT in collaboration with the Utah Department of Public Safety (DPS), Zero Fatalities and Bike Utah. The goal of the campaign is to educate both cyclists and drivers about state safety laws and encourage mutual respect on the road.

The centerpiece of the Road Respect campaign has been an annual, statewide cycling tour to teach cyclists proper road etiquette and educate drivers on sharing the road. The Road Respect Tour – which is led by representatives from UDOT, DPS, health agencies, law enforcement and cycling advocates – also holds community events along the route to promote safe cycling.

The ongoing success and popularity of the campaign led UDOT to develop the Road Respect Community program to work directly with communities to help them improve their active transportation options.

"The Road Respect Community Program is a big asset to UDOT because it offers Utah's cities and towns opportunities to expand their bicycle and active transportation programs based on the needs and desires of the community,” according to UDOT Executive Director Carlos Braceras. “Because the program reaches people on the grassroots level, it encourages communities to 'own' their planning process, while opening avenues of communication between UDOT, local municipalities, and active transportation advocates across the state," he said.

“What we found as we went from community to community on the tour is they were very interested in promoting bicycling and growing their bicycling programs, but they needed a little bit of guidance on doing that,” said Evelyn Tuddenham, Bike-Pedestrian Coordinator at UDOT.

Comprehensive Approach

UDOT sought to design a comprehensive program to help communities advance their bicycle planning programs. To do so, the department developed a set of criteria based on League of American Bicyclists requirements for Bicycle Friendly Communities and other bicycle planning criteria. These criteria were used to develop checklists of actions communities can take to earn the title, “Road Respect Community,” Tuddenham said.

The program features three Road Respect Community Levels – Activate, Ascend and Peak – with corresponding requirements leading up to applying for League of American Bicyclists’ Bicycle Friendly Community status. Requirements include:

Level 1 – Activate

  • Identify a community champion for bicycle planning efforts
  • Identify the health, community and economic benefits of a bicycle plan and set up initial evaluation criteria including health impact assessment guidelines
  • Start an inventory of bike infrastructure and identify connectivity gaps
  • Develop a kid’s bicycle safety program
  • Collaborate with local law enforcement to incorporate bike safety and enforcement

Level 2 – Ascend

  • Involve bike advocacy groups/individuals in planning efforts
  • Initiate “share the road” dialogue between drivers and cyclists
  • Develop the bicycle plan by identifying potential solutions
  • Roll out a local law enforcement bicycle safety and enforcement program
  • Evaluate the plan under development with the criteria identified in Level 1 and including health impact assessment

Level 3 – Peak

  • Adopt the bicycle plan and begin its implementation
  • Work with businesses to determine and promote the economic benefits of bicycling and plan for bicycle amenities
  • Develop and conduct bicycle safety campaign promoting respect between drivers and bicyclists on the road
  • Evaluate the bicycle plan
  • Apply for League of American Bicyclists’ Bicycle Friendly Community Status

As of May 2015, 12 cities or counties around the state had been designated as Road Respect Communities. Eight more cities and counties are slated to join in 2015, and at least seven more are in line to come onboard in 2016.

Consultation and Recognition

After a community has applied, UDOT conducts a forum to address local issues and generate potential solutions. The forum brings together representatives from UDOT, planning and law enforcement agencies, cycling advocates and other stakeholders to discuss the needs of the roadway and how they can work together to improve conditions for bicyclists. The forums have been very successful in getting issues out on the table and coming up with preliminary plans for communities to move forward, Tuddenham said.

For example, UDOT conducted a forum to help the city of Moab find bicycle-friendly solutions for its Main Street, a heavily used corridor serving business, trucking and travel. The community and cycling groups were looking for ways to help cyclists safely use Main Street to access the trails at the nearby Arches and Canyonlands national parks. The forum helped educate local stakeholders about their options on the multi-use corridor, and together with UDOT they came up with a plan for mapping and signs. Moab has since earned recognition as a Level 2 Road Respect Community.

The Road Respect Community program also offers promotional opportunities to highlight communities’ commitment to developing active transportation solutions. UDOT produces a Road Respect Community newsletter with resources including information about grants and funding, Tuddenham said. UDOT also has developed an interactive map on its website highlighting the Road Respect communities, including links to local information on bicycling and tourism.

Communities that participate in the program also are encouraged to apply for League of American Bicyclists’ Bicycle Friendly Community recognition. When they complete all the Road Respect requirements “they are perfectly positioned to do that,” according to Tuddenham.

Collaborative Approach

The program offers a model of a collaborative approach to building an integrated transportation system, according to Tuddenham.

The program has been very successful in bringing together state agencies that may not be involved in infrastructure but are involved in promoting active transportation, Tuddenham said. For instance, UDOT has worked closely with the Utah Department of Health. The health agency has offered $3,000 grants under its Cancer Control Program to help prospective Road Respect communities get started with their bicycle planning.

The program also improves communication between communities and UDOT regarding active transportation, Tuddenham said. When working with a Road Respect Community, members of UDOT and its regional offices “know they are dealing with a community that has an understanding of what it takes to install infrastructure and what it takes to work with UDOT as an agency,” Tuddenham said.

In addition, the program has helped channel the enthusiasm of cycling advocates, Tuddenham said. In 2015, the League of American Bicyclists ranked Utah fifth among the states in bicycle friendliness, the state’s highest ranking ever.

“In a short period of time we’ve made some really impressive and very strategic advances [for bicycling] in Utah, and I think a lot of that has been because of the collaborative approach that’s come about through this program,” Tuddenham said.

Transferability and Lessons Learned

The program is very transferable to other state DOTs, according to Tuddenham. However, she emphasized that in the beginning “you have to have a hook, you have to have something that really sparks people’s imagination to get them to come on board,” Tuddenham said. For Utah it was the Road Respect Tour, but for other states it might be something different, she said.

Tuddenham also stressed the role of agency leadership. “It’s a very grass-roots program, and that’s the strength of it…people want to be involved because they see it make a difference on their level,” she said. It is important that those at the top of the organization understand and are supportive of what’s going on at the community level, she said.

In Utah, the program has benefited from the support of UDOT Executive Director Braceras, an avid cyclist himself who has participated in numerous Road Respect events. Braceras has been a big supporter of the agency’s commitment to active transportation.

Recent Developments: Report Assesses Electric Vehicles for Commercial, Nonroad Uses

The Energy Department’s Oak Ridge National Laboratory has issued a report on the potential for using electric vehicles for government, commercial, and industrial purposes. The report focuses on highway vehicles that are not personal transport; non-highway modes such as rail, watercraft, and airport support; and non-road equipment used directly or in support of other uses. The report finds that electric vehicles are poorly suited for long-haul trucking but have potential for other vehicles where savings on fuel costs could be significant, such as transit buses, school buses, regional and local delivery trucks, utility service vehicles, and refuse trucks. The report also finds that low supply and low demand is hampering the development of options for commercial fleets, and that successful development will be a long process involving research and development, manufacturing, purchasing, and new regulations.

Case Studies: Georgia - Georgia DOT's Commuter Program Leverages CMAQ Funds for Travel Demand Management

The Atlanta metropolitan area is one of the fastest growing population centers in the nation, and the Georgia Department of Transportation is working to make sure that having more people does not mean having more air pollution.

To accomplish that, GDOT has a suite of air quality initiatives, including diesel retrofits, improvements to highway incident management, and traffic signal optimization.

Of these, one of the lowest cost efforts with measurable results is Georgia Commute Options, GDOT’s travel demand management program operated in partnership with the Atlanta Regional Commission and local Transportation Management Associations (TMAs).

The program provides multiple benefits to the dynamic Atlanta region, according to Phil Peevy, GDOT’s Air Quality and Technical Resource Branch Chief. Congestion on the area’s highways is reduced when residents choose alternatives to driving by themselves, eliminating approximately 1.1 million vehicle miles traveled daily. Also, air pollution emissions are reduced by an estimated 550 tons per day.

Additionally, there are the intangible benefits of creating a more livable, friendly community for residents. “It is such a beneficial overall project,” Peevy said.

Managing Travel Demand: A Low-Cost Option

Georgia Commute Options operates with funding from the Federal Highway Administration through its Congestion Mitigation and Air Quality Improvement (CMAQ) Program. Recent studies and information from the FHWA indicate that travel demand management is a low cost but effective means of reducing air emissions. As compared to other programs such as transit upgrades or diesel retrofit programs, travel demand management ranks sixth in funding but third highest in total projects obligated.

Georgia Commute Options tackles the problem of single-occupancy vehicle travel in a number of ways. For instance, the program facilitates carpooling by making it easier to find people to share a car with. Those interested in participating can register at the program website where they will be joining tens of thousands of people already participating. The program matches carpoolers together based on where they live and where they work.

Additionally, the Georgia Commute Options offers a “Guaranteed Ride Home” option in which registered carpoolers can receive up to five rides per year—with some restrictions—in any of 20 counties in the region.

Georgia Commute Options also promotes vanpooling, which can carry up to 15 passengers to work. As with carpools, the program website helps participants find vanpools that operate close to home and work and includes the guaranteed ride home for unexpected situations. Public education and outreach for the carpool and vanpool programs are “100 percent eligible” for CMAQ funding, Peevy said.

Employers can partner with Georgia Commute Options to provide incentives to their employees to find commuting alternatives. The program provides free services to partners, such as consultations, metrics, webinars on alternative work arrangements, onsite events, and customized employee surveys. By offering alternative transportation options to commuters, these programs help employers to boost employee morale, enhance recruitment efforts, and reduce parking and facilities costs, Peevy said.

At present, more than 1,600 employers and property managers are participating, according to the website, and awards are presented annually in recognition of excellence.

Having a telework program is one thing an employer can do to participate, and Georgia Commute Options provides assistance, webinars, and a toolkit to design a program that works best for a company or organization. Sample policies, telework agreements, and memos to management, as well as surveys and checklists are some of the resources available on the website. Georgia Commute Options also sponsors a yearly Telework Week to train both workers and managers on successful telework arrangements.

Biking to work also is supported and promoted by Georgia Commute Options. The program offers on its website links to information regarding trails and other bicycle facilities, bike safety classes and advocacy, and a smart phone application developed by Georgia Tech that records bicycle travel data. Also, there are links to bicycle maps issued by the Atlanta Regional Commission and to GDOT standards, planning and guidance for bike and pedestrian facilities. Annually, the program sponsors a bike challenge, according to Peevy, which includes a series of outreach events.

Additionally, the Georgia Commute Options website provides links and information regarding nearly 20 transit systems both within the metropolitan Atlanta region and in other parts of the state. For example, the recent initiation of streetcar service in downtown Atlanta provides a new transit option that interconnects with the heavy rail system operated by MARTA, to fill in gaps in the public transportation system. The streetcar, a joint operation headed by the city of Atlanta, currently covers 2.7 miles with plans for future expansion throughout the downtown central business district.


Georgia Commute Options uses the power of technology to educate commuters, consolidate resources, and disseminate information, mostly through the program website. GDOT used a consultant to develop and provide ongoing operation of the website, according to Peevy. “However, Georgia DOT owns the website,” Peevy said.

Using resources from a previous website created by GDOT, the consultants made some enhancements and relaunched it as “Over the past year, improvements have been made to streamline the website to make it easier for users to find information, request materials, and sign up for Georgia Commute Options programs,” Peevy said.

In addition, to the website, the program holds a variety of events across the 20-county Atlanta area each month to educate commuters about the program.

Incentive Program

A key piece to attracting new participants is the incentive program for clean commuters which is funded with CMAQ funds, these incentives include:

  • $3 a day, up to $100, for commuters to try out a clean commute option and log their trips on the program website;
  • a $25 prize from a monthly drawing of the commuters who log clean trips on the website;
  • $40-$60 monthly gas cards for carpools, depending on ridership; and
  • a $50 vanpool ride referral, for vanpoolers who refer a new vanpool rider and the new rider completes three consecutive months in a vanpool.

The incentives have been successful so far at reducing single-occupancy vehicle travel. Citing studies conducted by the Center for Transportation and the Environment on behalf of GDOT, Peevy said that with the $3-a-day program, 85 percent of the participants have continued with their clean commuting choices for as much as 24 months after completing the program.

Furthermore, the Georgia Commute Honors are held annually to recognize employer partners, property managers and individual commuters for their outstanding efforts, according to Peevy. “Publicly recognizing the employers that go the extra mile to make clean commute programs available to their employees goes a long way toward making those partners feel valued by the program, and thereby makes them more likely to continue their efforts,” Peevy said. The honorees are all participants in CMAQ-funded programs, Peevy said, and the ceremony is covered by a combination of CMAQ and state funds.

Lessons Learned

Georgia Commute Options is essentially attempting to change human behavior, and “it takes a while to do that,” Peevy said. He said the program tries to “focus on the long-term change.”

Also, since Georgia Commute Options is a completely voluntary program, “gas prices play a major role in participation numbers,” Peevy said. When gas is inexpensive and plentiful, participation in the program goes down, Peevy said.

Additionally, Atlanta has a federally-designated “smog season” that runs from April 1 to October 31. That is the busiest time for transportation demand management programs, and the best time for Georgia Commute Options to roll out new incentives and programs, Peevy said.

In 2015, for instance, the program offered the “Commute Pursuit,” a challenge to find better commute options. The challenge, which ran until July 31, included cash incentives to find a carpool, answering daily trivia questions about commuting, and posting pictures of clean commuting to social media. The promotion spurred an increase in participation. More than 500 people registered with Georgia Commute Options during the promotional period, with 101 of these commuters entering the $3 a day programs.

In regard to the incentive programs, a consultant handles the day-to-day operations. “Each month, the contractor runs reports to determine which commuters are eligible to win prizes then sends the prize recipients an e-mail with instructions to redeem their reward,” Peevy said. The prizes can be in the form of Visa reward cards, or in some cases a retail purchase reward, according to Peevy.

Peevy said the Georgia Commute Options program could easily be modified for use in other states, noting that there are a few states that have already done this exact thing.

“I would also recommend to anyone starting a new program from the ground up to keep their initial goals realistic and understand these programs can take time to get up and running,” he added.

Case Studies: California - Caltrans Works to Advance 'Smart Mobility' Approach

Since 2010, the California Department of Transportation has been working to implement a new vision for integrating transportation and land use decisions that promises to combine a range of familiar solutions taking hold across the nation: smart growth, livability, context sensitive design, transit-oriented development, complete streets, and sustainability.

Caltrans’ “Smart Mobility 2010” framework was developed to ensure that the state’s transportation investments achieve balanced outcomes for mobility, environmental protection, social equity, and economic growth – all backed by specific performance measures.

Caltrans describes the concept as follows: “Smart Mobility moves people and freight while enhancing California’s economic, environmental, and human resources by emphasizing: convenient and safe multi-modal travel, speed suitability, accessibility, management of the circulation network, and efficient use of land.”

Developed using a smart growth program grant from the Environmental Protection Agency, the framework establishes six Smart Mobility principles to be applied based on specified place-types, each with its own set of performance measures.

The six principles are:

  • location efficiency,
  • reliable mobility,
  • health and safety,
  • environmental stewardship,
  • social equity, and
  • robust economy.

Under the Smart Mobility approach, transportation planning and design would be conducted based on seven newly established place-types: urban centers, close-in compact communities, compact communities, suburban areas, rural and agricultural lands, protected lands, and special use areas.

For each place type, performance measures would be targeted to align with the principles. Types of performance measures include the following:

  • support for sustainable growth;
  • transit mode share;
  • accessibility and connectivity;
  • multi-modal travel mobility, reliability, service quality, safety;
  • design and speed suitability;
  • pedestrian and bicycle mode share;
  • climate and energy conservation;
  • emissions reduction;
  • equitable distribution of impacts;
  • equitable distribution of access and mobility;
  • congestion effects on productivity;
  • efficient use of system resources;
  • network performance optimization; and
  • return on investment.

Interregional Blueprint Process

The plan also calls for a “transformed state transportation planning process” developed through a multimodal “Interregional Blueprint” process, incorporating transportation and land use planning efforts underway by regional and metropolitan planning organizations in the state.

California is subject to some of the nation’s most ambitious environmental and sustainability goals, including the landmark Global Warming Solutions Act (AB 32), under which the state must reduce greenhouse gas emissions to 1990 levels by 2020.

In addition, Senate Bill 375, enacted in 2008, requires regional targets for reducing greenhouse gas emissions from passenger vehicles. SB 375 – which has been touted as a possible national model for transportation planning – establishes a process and incentives for the creation of integrated regional land use, housing and transportation plans called “sustainable communities strategies.” Building on these regional efforts, SB 391 passed in October of 2009, requires that the California Transportation Plan prepared by Caltrans identify the statewide multimodal transportation system that will achieve the state’s climate change goals.

The California Interregional Blueprint, a statewide land use-transportation plan will integrate the state’s various modal plans and incorporate individual blueprints developed by regions across the state. Caltrans currently administers the California Regional Blueprint Planning Program for regional transportation planning agencies to conduct comprehensive scenario planning, bringing together a range of stakeholders to develop preferred long-range growth scenarios.

The Interregional Blueprint will incorporate the Smart Mobility principles and improve modeling and data gathering, serving as the foundation for the next update of the California Transportation Plan. The Interregional Blueprint planning process is underway.

Next Steps

A number of short-term actions will be undertaken between 2012 and 2014 to develop and test approaches to implement the Smart Mobility principles and performance measures. These include applying the framework in separate planning efforts in the northern and southern portions of the state. The agency plans to document these efforts and develop a “how-to” guide for implementation.

The vision for using the framework is described by Caltrans as follows:

  • find your place type;
  • forecast transportation needs;
  • apply Smart Mobility principles;
  • assess Smart Mobility Performance;
  • prioritize transportation investments;
  • achieve Smart Mobility.

Additional Efforts

Other efforts include a Caltrans-funded study, Improved Data and Tools for Integrated Land Use-Transportation Planning in California, which was completed in October 2012. Over a three-year period, the project team collected and analyzed data on land use-travel relationships at more than 200,000 locations in most of California. The project provided a final report as well as analytical tools for use in “sketch”-planning tools, which local and regional agencies use to assist in developing scenarios, and travel demand forecasting models, which are commonly used to analyze resulting scenarios. These products will be helpful to regional agencies in their Blueprint and sustainable community strategies and regional transportation planning, and to local governments for their planning efforts. Another significant Caltrans effort has been implementation of its complete streets directive.

Caltrans also has completed a survey, “Smart Mobility: A Survey of Current Practice and Related Research,” that looks at federal, state and regional activities to assess the current state of the practice of sustainability-oriented planning and performance measurement

Case Studies: Massachusetts - MassDOT Public-Private Partnership Generates Solar Energy on Highway Rights of Way

Generating 6 megawatts (MW) of electricity per year from solar farms is not a typical goal for a state transportation agency. But for Massachusetts DOT (MassDOT), setting that goal is part of a 20-year public-private partnership it has embarked upon with a renewable energy company located in the eastern part of the state.

Under the contract, the private sector partner has agreed to finance, develop, design, construct, commission, operate, maintain, and eventually decommission solar facilities at ten pre-approved sites it leases across the state. The rows of ground-mounted solar panels are located on small parcels of state-owned land along highway embankments, exit ramps, and service plazas.

Phase 1A of the MassDOT Highway Right of Way Solar Photovoltaic Energy Program was completed in October 2015 and included five locations. Phase 1B, comprising five additional locations, is awaiting start of construction. And Phase2A, as envisioned, will include three additional sites.

“We are very pleased to be spearheading an initiative that is bringing both economic and environmental benefits,” says Hongyan Oliver, Project Manager of the solar program.

“The state expects to generate at least $15 million in savings over the contract period. These savings include about $2 million in rent from the leases on state properties, money that goes into the state’s transportation fund. What’s more, the arrangement entailed zero upfront capital cost for us,” according to Oliver.

Another advantage of forming a public-private partnership is the generous incentives available to the private sector partner. In this case, besides receiving a federal income tax reduction, its partner also is tapping into the state’s Solar Renewable Credits (SREC) system. For its part, MassDOT obtains all net metering credits and associated energy savings. The state’s net metering policy allows a customer to sell power generated by distributed generation back to the grid at a certain price (the meter spins backwards).

“We are purchasing 100 percent of the electricity these solar farms are generating,” explains Oliver. “And because our partner is benefitting from the solar incentives, the purchase rates we have been able to negotiate are significantly lower than current utility rates. At this point, the solar power from the ten planned sites can meet approximately six percent of our needs; we expect that figure to rise as more solar farms from our partnership enter the grid.”

The solar program also brings strong environmental benefits. The power being generated will produce zero greenhouse gas emissions, says Oliver, thereby supporting Massachusetts’ commitment to a green and clean economy. It also supports MassDOT’s GreenDOT sustainability initiative.

“Once we fully reach our goal of generating 6 megawatts (MW) of electricity per year, we anticipate a CO2 emissions reduction of approximately 6.8 million pounds annually due to replacing fossil fuel electricity in the grid with solar power,” Oliver explains. “That is the equivalent of annual greenhouse gas emissions from 630 passenger vehicles.”


MassDOT has joined a small but growing number of state DOTs that are beginning to utilize highway rights-of-way (ROW) as locations for siting renewable energy production facilities. Oregon led the way in 2008, becoming the first agency in the United States to install a solar panel array along a highway ROW (see related case study). Over the next several years, Ohio and Colorado followed suit. In addition, at least seven state DOTS have constructed solar array or wind turbine installations at rest areas or carports that abridge highways, according to a recent FHWA publication.

Original Impetus, Careful Site Selection

The agency began its foray into the solar energy field in 2011 by releasing a parcel of state land adjacent to a highway to the adjoining town. The town had received an American Recovery and Reinvestment Act grant to produce solar power for its water treatment plant.

“Actually, we received indirect benefits from the project in that the public began to become accustomed to the concept of solar panels being installed next to a highway,” Oliver explains.

During that same year, her agency was beginning to have discussions about developing what now is the MassDOT solar program.

“One of the first things we did was contact our counterparts in Oregon,” Oliver explains. “Although the business model we eventually selected was different, many other components were the same. ”

The agency began with a small pilot project in the western part of the state designed to supply one-third of the energy needs of a nearby District Highway Administration building. Then it was time to move into the next phase, its multi-facility program.

“Realizing that site selection was one of the most critical elements, we hired a consultant to do the evaluation,” says Oliver.

Criteria for selection included parcel size and orientation, any existing environmental concerns, distance from the grid, easy access during construction, no interference with highway operation, and no conflict with future transportation use. Another consideration was whether a site was adjacent to a federally-funded highway, which would mean obtaining FHWA approval. Finally, if either environmental concerns or a solar zoning by-law was present, town approval would be needed.

Once sites were selected, a Request for Response (RFR) was sent out and the current partner company was selected after a three-stage competitive process. Prior to the issuance of the RFR, the Department updated its utility accommodation policy in coordination with the FHWA Mass division. Its policy now includes guidelines for renewable energy technologies. It also outlines safety criteria and design standards, the project development process, compensation requirements, and relevant license and lease agreements.

Multiple Installations, Multiple Advantages

“Developing multiple sites across the state under the same program umbrella makes us somewhat unique,” says Oliver. “From our perspective, this approach has a number of advantages.”

First, she explains, it requires only one procurement document, and the process is carried out through a single open bid. Second, with multiple sites in the same project, the owner and operator of the solar farms may be able to purchase equipment and subcontractors’ services in bulk at a discount, and construction mobilization can occur at multiple sites simultaneously.

“In addition,” according to Oliver, “we have been able to learn through experience as we move through the program and integrate more strategic approaches along the way.


Other states may be well positioned to create similar programs, she said. Those that decide to pursue such a program should be aware of any site conditions or regulatory constraints that can affect generation capacity as well as available incentives.

“In our case, for instance, construction for the five sites in Phase 1B originally was slated to begin in spring 2015. However, that start date has been put on hold due to the situation of excess-demand for net metering incentives in Massachusetts.”

Oliver also advises that other states “work very closely with other divisions and sections to incorporate all concerns and requirements during site selection and development.”

Fortunately, she continues, her Planning Division uses a 25-year projection window, an extremely compatible timeframe in this case. She and her team members maintained constant communication throughout the process, especially during site selection.

Oliver concludes, “So far, the decision to use some of our highway right-of-way land to produce solar energy has proven to be extremely sound. And looking ahead, we anticipate only more of the same. ”

Case Studies: Oregon - 'Solar Highway' Offers Model Approach for Renewable Energy

An array of hundreds of solar panels stretching 540 feet along an Oregon highway is helping to power a nearby interchange with clean, renewable energy through a unique public-private partnership that could serve as a model for the nation.

Oregon’s “Solar Highway Project” sits at the interchange of Interstates 5 and 205 in Tualatin, Ore., at the south end of the Portland metropolitan area. The project is the nation’s first roadside solar photovoltaic demonstration project.

According to the Oregon Department of Transportation, the project’s 594 solar panels produce about 122,000 kilowatt hours annually. The panels produce energy during the day which is used to light the interchange at night. ODOT buys the energy produced by the array at the same rate the agency pays for regular energy from the grid.

This clean, renewable source of energy will help the agency meet the mandate from Oregon Gov. Ted Kulongoski that state agencies obtain all of their electricity from renewable sources. By replacing energy from the grid, the solar electricity produced by the project will avoid the production of nearly 43 metric tons of carbon dioxide equivalent emissions each year.

The $1.28 million project, which has been in operation for just over one year, was developed through an innovative public-private partnership between ODOT; Portland General Electric (PGE), Oregon’s largest utility; and US Bank. Material providers included Solar World US, the nation’s largest solar panel manufacturer, and PV Powered, the nation’s largest inverter manufacturer.

Making the Most of the ‘Right-of-Way Asset.’

ODOT Project Director Allison Hamilton explained that under this unique partnership “the public gets multiple values out of its right-of-way asset.”

“Using state and federal tax credits, the renewable energy projects are developed at least possible cost, which benefits the utility rate payers – including ODOT and the State of Oregon, “ Hamilton said. At the same time, ODOT gets green energy at grid rate instead of the higher green energy rate, she added.

“The solar energy project is owned, operated and maintained by the utility, which also assumes all the risk, and is responsible for maintenance of the right of way for the term of the contract (from 25 years up to 40 years or more),” Hamilton explained. But the utility also gets to count the project towards its renewable energy portfolio requirements, she said.

“It’s a win-win-win business model,” Hamilton added.

ODOT officials and PGE officials have deemed the project a success, demonstrating that solar arrays can complement and not compromise the transportation system.

In fact, Hamilton said the project has exceeded expectations, producing more than the expected 112,000 kilowatt hours in its first year, with only one maintenance incident where a panel was cracked and had to be replaced.

As a result, Oregon DOT and its partners – utility providers and private businesses – are poised to expand production of solar energy at the demonstration site and as well as other locations in the state.

Third Party Financing Model

According to ODOT, these public-private partnerships are expected to follow the same type of third-party financing model developed for the demonstration project.

“The utilities would contract with solar developers to design, build and install the arrays, which they – the utilities or limited liability companies involving the utilities – would own, operate and maintain, and which could count towards meeting statutory requirements to develop renewable energy resources. The utilities would also be responsible for maintenance and successful operation of the arrays, including any damage due to vandalism or crashes,” according to a summary on the demonstration project website.

ODOT would have a 25-year agreement to purchase all electricity generated by the solar projects, with options to renew for up to three five-year extensions.

DOTs Urged to Work with Utilities

Hamilton said many other states have expressed interest in following Oregon’s lead, but she stressed that each state will have unique circumstances. “Because each state has its own utility regulations, I would recommend project proponents work with or through their utility to learn the most efficient and cost effective way to size, permit and connect a project, and also to determine the most advantageous financing and ownership model,” she said.

“We learned that the larger the installation, the better, as you are able to spread your fixed costs out over more kilowatts, bringing down the cost per installed kilowatt” compared to the cost of existing grid energy.

Hamilton urged transportation agencies that are interested in developing a solar highway project to take advantage of the expertise of the utility, whose core business is energy generation.

“Oregon’s state transportation system has nearly 19,000 lane miles of right-of-way and there are more than 8 million lane miles of right-of-way across the nation,” according to an ODOT project summary. “Solar arrays on less than 1 percent of Oregon’s right-of-way could supply the nearly 50 million kilowatt hours needed annually by the state transportation system,” the agency said.

The project has been recognized with numerous honors, including the Federal Highway Administration’s 2009 Environmental Excellence Awards.

A wide range of information is available on the project website,, including a solar highway meter that tracks energy generated on-site, news releases, photos, videos, research, technical documents, and information on planning for future projects.

Case Studies: Tennessee - Tennessee DOT's 'Green Islands' Program: Distributing Renewable Fuels Across the State

The Tennessee Department of Transportation (TDOT) is promoting the use of renewable fuels across the state, increasing the number of fueling stations that offer renewables through its “Green Islands” program.

While E10 (a mixture of 10 percent ethanol and 90 percent gasoline) is now widely available, an increasing portion of the U.S. automobile fleet has been manufactured to be "flexfuel," and able to use E85 (a mixture of 85 percent ethanol and 15 percent gasoline). Additionally, most diesel engines are able to use B20 (a blend of 20 percent biodiesel and 80 percent petrodiesel). However, a major impediment to increasing adoption of renewable fuels such as E85 and B20 is the lack of infrastructure to distribute the fuel.

TDOT faced this issue by helping establish a "green islands biofuel corridor network" of fueling stations not more than 100 miles apart along the highways that connect the state's major cities and destinations. The goal of "green islands” is to enable travel across the state using biofuel exclusively. These alternative fuel stations provide public access to biofuels along major corridors for consumers wishing to use them and reduce their consumption of fossil fuel. While some gaps in the network remain, TDOT will continue to offer grants to fuel stations as incentives to fill the gaps.

“Increasing the availability and use of biofuels in Tennessee will help increase energy security, reduce air pollution and benefit the state’s economy, according to Alan Jones, Manager of the Policy Office in TDOT’s Long Range Planning Division. “The Green Islands grant program encourages fuel stations to offer these fuels to the driving public,” he said.

‘Farm to Fuel Tank’ Vision

The benefits of reducing fossil fuel consumption and displacing imported petroleum with alternative fuels have been discussed for many years. However, the "green island" concept accelerated in the early 2000's when the Tennessee Farm Bureau started investigating how the state's agricultural community could assist in biofuel production. A vision of a vertically integrated biofuels industry wholly within Tennessee ("From Farm to Fuel Tank in Tennessee") began to take hold.

The Tennessee legislature was called upon to pass legislation to implement the vision. Proponents discussed obtaining seed money, such as grants, to advance the concept. The legislature determined that encouraging in-state biofuel production was in the state's economic interest, and therefore worth providing incentives. One law passed by the legislature named the TDOT to be the agency to manage a grant program for fuel stations to encourage increased availability of biofuels to motorists and vehicle fleet owners in the state. The grant program offered funding to purchase and install biofuel storage and fuel dispensing equipment across the state. TDOT stepped up, administering a program to provide public access to the fuel.

TDOT has since published several Requests for Proposals (RFP) aimed at gas stations willing to make biofuels publicly available for four years, in return for grant funding to help purchase and install the infrastructure. A subsidy was set at a maximum of $45,000 per biofuel pump. The maximum grant was capped at $90,000 for a single location, if the station proposed to sell both biofuels, E85 and B20, to the general public.

While most applicants proposed one or two pumps, several owners proposed multiple stations to achieve economies of scale. One owner proposed three locations, and received a total benefit of $270,000. Presently there are 60 E85 pumps statewide. Around half were installed by private sector operators deciding on their own to offer biofuels to their customers.

When stations meet their four-year contract obligation, many continue to sell the fuels, but some do not. Stations that have been the most successful helped market the fuel on their own. The vision of "From Farm to Fuel Tank in Tennessee" remains, although increasing the use of biofuels has lagged for numerous reasons. State grant funds remain available for stations still interested in selling alternative fuels.

Funding for the program has come from several sources. The state's first E85 pump, which came on-line in 2003, was funded by the U.S. Department of Energy. In air quality nonattainment areas, TDOT used funds from the Federal Highway Administration's Congestion Mitigation and Air Quality Improvement Program. TDOT also received significant state funding from the state’s General Assembly for the green islands program.

An important part of the program includes increasing public awareness about biofuel, its benefits, and where drivers can purchase these cleaner fuels. As part of the interstate blue logo sign program, TDOT developed and posted blue signs with a biofuel image to advertise the locations of green island stations.

Grants provide an incentive for fuel stations to install the fueling infrastructure but, in the long run, stations will not continue to sell biofuels unless their customers buy them. Sustaining market demand for biofuels will require a more vigorous advertising and public education campaign at the state and national level.

Case Studies: Vermont - Vermont’s Solar Power Plan Aims to Help Meet Renewable Energy Goals

The Vermont Agency of Transportation (VTrans) expects to use an increasing number of properties and rights-of-way for the installation of solar power projects that could help the agency meet its renewable energy goals, reduce emissions and save money, joining seven other state departments of transportation in developing such facilities.

The Vermont Agency of Transportation Solar Plan was issued in December 2016 to help with the complex decision making involved in siting and operating solar projects.

The plan defines for the agency the costs, benefits and processes of solar photovoltaic (PV) installation in the state, with the goal of understanding and navigating toward successful solar developments. The plan is required by state law, but just as importantly it serves to communicate the agency’s goals to the public, said Gina Campoli, a retired VTrans project manager who oversaw the plan development.

“The former [state transportation] secretary felt it was very important for the public to understand the various processes that we were using to develop projects, [including] why we were developing projects, why on Earth the Agency of Transportation was getting into the solar business, what were the processes we were going to use when we planned projects, just like we would for a transportation project,” Campoli said.

Vermont joins a growing number of state DOTs, including Arizona, Connecticut, Florida, Massachusetts, Minnesota, Ohio and Oregon, that are beginning to use transportation properties for siting renewable energy facilities, according to the plan. Vermont used Oregon DOT’s solar plan as a reference for their own, even commissioning the same consulting firm to prepare the plan, Campoli said. (See related case studies for Massachusetts and Oregon.)

Solar PV at VTrans

There has never been a better time for VTrans to install solar generation, according to the plan. It describes several factors driving the momentum for solar PV at VTrans. These include:

  • Saving on energy costs. Systems that VTrans has already installed in Rutland and at various maintenance garages statewide are providing significant cost savings for electricity, with the project at the Rutland State Airport expected to save the agency $400,000 over 30 years.
  • Installation costs are going down each year. Using VTrans staff for construction saves even more on up-front costs, a strategy the plan recommends for smaller projects.
  • Aligning with state policies to consume cleaner energy, mitigate climate impacts, and build resilience. In the event of an emergency loss of power, PV systems can provide continuous power to VTrans or to feed power back to the grid, creating greater resilience.

Also, the Vermont state Comprehensive Energy Plan sets an ambitious goal of having 90 percent of the state’s energy needs—both state government operations and the private sector—met by renewable sources by 2050, Campoli said. For VTrans, that means power for street lights, traffic signals, all of the equipment in the maintenance garages, computers and office lights. “There is a ton of power we consume,” Campoli said.

The state energy planning requirement has allowed VTrans to document and better understand its energy footprint, Campoli said. Knowing the amount of energy use “justifies the investment in solar,” she said.

“There is enough sun in Vermont,” Campoli said.

How to Implement

The plan discusses how VTrans—or any other state DOT—would pursue development of more solar PV projects, steps that include assembling a project team, evaluating potential project sites, evaluating financial arrangements and ownership models, performing due diligence, and final implementation.

At VTrans, a team has already screened candidate sites at VTrans-owned properties and highway rights-of-way sites. Using tools such as VTrans’ geographic information system, the mapping office found that 124 out of 375 sites demonstrated potential for solar PV. Further screening has narrowed the list to 24 sites.

After sites are identified, VTrans must conduct analysis to determine whether the site merits continued development. Such analysis includes a study of the requirements for utility interconnection, environmental impact analysis at the state and, if necessary, federal level, and engagement with stakeholders and the public.

As a public agency, VTrans would need to investigate possible public-private partnerships including a power purchase agreement—where the agency agrees to buy electricity from the project developer—and a site license or lease agreement that grants a third party the right to install the system. Also, VTrans would need a net metering agreement with the local utility to allow the agency to receive credit for its power production, something VTrans is already doing with the solar arrays installed at maintenance garages, Campoli said.

Key Considerations

VTrans will need to make some organizational adjustments to continue to pursue solar projects. The plan recommends having a dedicated PV projects manager and the necessary support from agency leadership.

Additionally, VTrans must consider the markets for renewable energy, federal and state financial incentives, and regulations and policies with regard to renewables, including Vermont’s own renewable energy standard.

If using federal-aid rights-of-way, state DOTs must comply with all federal requirements including ensuring that vehicle safety and the transportation purpose are not compromised, and performing environmental review under the National Environmental Policy Act. Campoli noted that placing solar facilities within federal right-of-way increases the complexity of the project, and therefore nearly all of the projects VTrans has installed so far have been on state land. The 24 sites that VTrans has identified as having a high potential for solar PV are mostly either VTrans maintenance garages or regional airports.

According to the plan, if the project is for a public utility, siting and permitting can be managed in accordance with state's approved utility accommodation policy (UAP) without further FHWA approval. Facility types not currently in the UAP must be referred to the FHWA division office, and projects that are strictly for private use are subject to federal right-of-way use agreement regulations.

Lessons Learned

The VTrans renewables plan is part of a state planning effort that is an interagency collaboration including the Department of Buildings and General Services and the Department of Public Service, the state’s utility regulator, Campoli said. “We’ve broken down silos on this issue,” she said.

Also, the projects that are operational are already paying dividends. “The Rutland Airport is producing way beyond our wildest expectations,” Campoli said, noting that production can exceed what is promised by PV panel manufacturers.

Additionally, more land with solar panels equals more solar power generation. However, it is important to site the solar panels in locations that consider future transportation needs, Campoli said, by making sure that the panels are not where a future storage area or parking lot will need to go. Meeting the agency’s goals for renewables will require VTrans to find additional sites, such as interchanges or cloverleaves, former quarry or gravel sites, brownfield sites, inactive or abandoned weigh stations, and park and ride areas, the plan said.

Next Steps

VTrans has set a renewable electricity goal for the agency of 25 percent. To meet that target, an additional 610 kW of capacity—that generates 715,000 kWh—is needed. This capacity is equivalent to an additional seven projects like the system installed in 2016 at Fair Haven Welcome Center or 36 additional 15 kW garage projects.

For these larger PV facilities, such as the 75 kW Fair Haven project within the federal right-of-way, the agency will need to establish partnerships. VTrans also should continue to coordinate with stakeholders such as the Vermont Energy Investment Corporation and the various regional planning commissions to determine if VTrans sites could meet mutually beneficial goals, the plan said.

Infrastructure Resilience

Recent Developments: TRB Webinar Focuses on Resilience for Transit Agencies

The Transportation Research Board will hold a webinar March 12 regarding resilience in transit systems.

Case Studies: Minnesota - MnDOT Strengthens Climate Resilience Using FHWA Vulnerability Assessment Framework

Transportation officials in Minnesota will be better able to assess vulnerability of transportation assets to flooding and select appropriate adaptation options for damaged and at-risk infrastructure following a pilot study conducted by the Minnesota Department of Transportation. “The potential for more frequent extreme precipitation is a major risk facing our state’s aging transportation system,” said Philip Schaffner, Director of Minnesota DOT’s (MnDOT) Flash Flood Vulnerability and Adaptation Assessment Pilot Project.

The project is one of 19 Federal Highway Administration (FHWA)-funded climate vulnerability pilot studies that were carried out between 2013 and 2015. Each of the studies drew from guidance contained in FHWA's Climate Change and Extreme Weather Vulnerability Assessment Framework (FHWA Framework).

The timing for the project could not have been better, Schaffner said.

In 2012, he explained, MnDOT had just identified climate-related flooding as a major risk to the system in the state transportation plan when Duluth experienced the worst flooding it had seen in centuries. It resulted in more than $100 million in damage to roads and other infrastructure. Other parts of the state also had recently experienced significant flooding. The state’s transportation system assets had not been originally designed to handle such extremely high levels of precipitation.

As it happened, Schaffner continued, at that same point in time, FHWA issued its second-round call for proposals to carry out pilot projects examining the effects of climate hazards on transportation systems. Unlike the broader first round of 2010-2011 pilots that primarily involved coastal locations, projects located inland were especially welcome.

MnDOT’s study had four goals:

  • Better understand the vulnerability of the state’s trunk highway system to flash flooding;
  • Increase system resiliency by developing a methodology to identify cost-effective design solutions;
  • Support the agency’s asset management planning work; and
  • Provide feedback on the FHWA Framework.

One of the first steps taken was to create two technical committees to support the core project team. The first was composed of hydrologists, hydraulic engineers and planners. The other was staffed with climatologists and other state agencies that helped the core team understand and appropriately use climate model outputs. Much of the funding went to hire an external expert who worked closely with the in-house team.

Overall Vulnerability Assessment

For Phase 1 of the study, the team carried out a system-wide flash flood vulnerability assessment of the truck highway system in two of its eight districts: District 1 in the northeastern part of the state, and District 6 in the southeastern part of the state. Both districts had experienced high levels of flooding in recent years.

The assessment focused on the vulnerability of four types of assets: bridges, large culverts, pipes, and roads parallel to streams. A total of 1,819 assets were given vulnerability scores. Dozens of metrics were developed to quantify each asset’s vulnerability. Assessment scoring was based on the FHWA Framework’s definition of vulnerability, which includes three elements: exposure to a climate stressor; sensitivity to climate stressors; and to what extent the transportation system as a whole can adapt if a particular asset is taken out of service. Findings provided a detailed snapshot of the two Districts’ assets’ vulnerability.

Assessment of Individual Assets’ Adaptation Options

For Phase 2 of the study, one high-risk culvert in each district was selected to examine in more detail in order to identify robust, cost-effective adaptation measures.

In District 1, the culvert was located along a stretch of the highway system that borders Lake Superior and already was on a list of assets to be improved. In District 6, the culvert lay beneath a road over a creek in a small town, and no improvements had been scheduled. The study teams examined vulnerability for both culverts under low, medium, and high climate change scenarios.

Adaptation options differed somewhat for each culvert. They included actions such as increasing the size of the culvert, replacing the culvert with a simple span bridge to improve fish passage, and enhancing the floodplain upstream of the culvert.

Next, a cost-effectiveness analysis for each option was carried out. The analysis considered both direct costs to MnDOT as well as social costs such as travel time costs to motorists taking detours. For one of the culverts, a clear adaptation choice emerged -- add cells to the existing culvert design. For the other culvert, the conclusion was more nuanced, depending upon whether or not the analysis included social costs.

Uniqueness, Challenges, Advice

One of the unique features of their pilot project, Schaffner said, is their use of proxy variables. For example, the team used an estimate of the percentage of the drainage area that was forested as a proxy for potential woody debris that could clog a pipe, culvert or bridge opening in the event of a flood.

As is the case for any pilot project, he said, there were challenges along the way. For instance, it was difficult to compile consistent and accurate data for more than 1,800 assets. And upon reflection, there were several factors that would receive greater attention and refinement should MnDOT decide to carry out a new group of assessments.

First, more time would be devoted to discussing how to most accurately weigh each variable. Second, adaptive capacity would be extended beyond traffic volume and detours, which were the primary considerations in the pilot study. In addition, the team would look to more advanced techniques of downscaling data from global climate models.

Schaffner said the FHWA Framework was valuable in providing a “high level” foundation for the project. However, although the team was able to turn to earlier projects for some guidance, it was left to them to develop a detailed methodology. In feedback to FHWA on its Framework, he and his team highlighted the need for greater detail and specificity in terms of metrics.

For other DOTs interested in carrying out a similar assessment, Schaffner advised that they start small geographically and to take their time to calibrate their vulnerability metrics. It also is important to involve your maintenance team and other regional staff, he said. So far as the ability to carry out the project without external consultancy/funding goes, it would depend upon the agency’s in-house skill level and access to data.

Findings from the study are being used to inform MnDOT’s long-range transportation planning and asset management efforts. At this point, though no decisions have been made, the agency is exploring carrying out similar assessments in several of its other districts as well as evaluating other types of vulnerabilities such as slope failure.

Schaffner’s view is that additional assessments likely could be done at much less cost given that the basic methodology already is in place.

”One of the important findings of our pilot project was that adaptation doesn’t always require large, complex projects. In fact, small changes over time can make a big difference in the resilience of the system,” he said.

Case Studies: Tennessee - Tennessee DOT Conducts Statewide Vulnerability Assessment for Transportation Assets

The Tennessee Department of Transportation is responsible for building and maintaining much of the state’s transportation infrastructure. Following a number of extreme weather events, the Tennessee Department of Transportation (TDOT) recognized that the agency’s management of those assets required methodological approach to assess the vulnerability of the state's transportation network.

In May 2010, Nashville, Tennessee experienced a 1,000-year flood event, causing 21 deaths in Tennessee and widespread property damage. In 2013, there were severe weather-related problems on the Cumberland Plateau, in the eastern part of the state. Rockslides blocked traffic in areas lacking alternative transportation routes. In other regions, sinkholes opened on interstate highways.

These types of extreme events prompted TDOT officials to conduct a statewide vulnerability assessment for its transportation infrastructure as a first step in identifying cost-effective approaches to increasing the resilience of the system. The assessment took advantage of a pilot program offered by the Federal Highway Administration (FHWA).

FHWA has funded a series of studies across the country to begin increasing the resiliency of the country's transportation infrastructure in the face of increasingly frequent and severe weather events. The first round of FHWA pilot projects validated a general approach to conducting an extreme weather vulnerability assessment. They focused primarily on coastal locations where many of the risks were related to storm surge and sea level rise. FHWA’s second round of pilots, although also primarily focused on coastal states, included inland states, and Tennessee became the first inland state to perform a statewide vulnerability assessment.

TDOT is now trying to integrate the results of the screening-level, statewide vulnerability assessment into TDOT’s planning, management and operational policies, according to Alan Jones, Policy Manager, Long Range Planning Division at TDOT. The agency’s assessment has been an important screening tool to identify critical transportation assets, better understand extreme weather risks, and identify specific assets that warrant a more detailed analysis.

FHWA Vulnerability Assessment Framework and Tennessee’s Approach

The Tennessee project developed an approach to the vulnerability assessment that was based on FHWA's Vulnerability Assessment Framework, while also taking into account the unique characteristics of Tennessee and its transportation system. The approach involved identifying critical transportation assets, defining the types of extreme weather events that could occur while taking into consideration expected changes in certain climate variables, assessing the damage potential and resilience of the transportation assets when impacted by the extreme weather event, and combining this information to reach conclusions about the vulnerability of the asset.

To manage the number and range of transportation assets statewide, TDOT's first step was to group its transportation assets into generic asset categories. The categories included roads, rail lines and rail yards, navigable waterways, ports, bridges, airport runways, pipelines, transit systems, and more. It was not possible in this initial screening study to differentiate the unique characteristics of specific facilities, such as pavement binder or age of asset.

Criteria for determining the criticality of an asset included the volume of activity, the asset's strategic importance, the existence of redundant capability, the asset's use for emergency response, and local knowledge of the importance of the asset.

The range of extreme weather events and climate change to be expected in Tennessee was based on analysis of information from the National Weather Service and well-tested global climate models. The types of weather events included were extreme temperatures (both high and low), heavy rain, drought, strong winds and tornados, ice storms, and major snowfalls. Trends in the data identified which counties were most likely to see increased severity and frequency of extreme events. The climate data also identified counties that can expect the most significant changes with respect to projected temperature and precipitation.

The process of assessing damage potential and asset resilience was performed through a statewide survey conducted of transportation stakeholders, such as government agencies, freight carriers, transit service providers, airport authorities, and shippers.

The survey results painted a picture of tremendous variation in vulnerabilities across Tennessee. Key findings included:

  • Wind and flooding are by far the events of greatest concern across the state, potentially affecting multiple classes of transportation assets. For example, there is significant risk from flooding in Memphis. Moreover, wet ground and strong winds could produce large numbers of tree falls and utility poles across roads, severely restricting movement.
  • Movement of vessels, including barges carrying coal and other products, on Tennessee rivers can be disrupted by extreme weather. Locks are vulnerable to flooding and river levels that allow barge traffic are vulnerable to extended periods of high temperature and low rainfall.
  • Rockslides in middle and eastern Tennessee could substantially disrupt transportation networks in areas with limited alternate routes.
  • With the exception of one county, winter weather is a less significant concern.

Next Steps for TDOT

TDOT plans to take a number of steps to implement the results of its vulnerability assessment.

The agency plans to follow-up with TDOT's four regions to communicate the results of the study. This will include developing regional "briefing books" to condense the study and communicate specific vulnerabilities so they can be easily understood and quickly referenced. These briefing books will be tailored to each of the four TDOT regions to account for differences across the State and to make the information more useful to local and regional planners. The agency also will select up to 20 of the state's most vulnerable assets for more refined, targeted analyses, including development of potential adaptation strategies.

In addition, TDOT will incorporate information from the screening-level vulnerability assessment as it develops its risk-based transportation asset management plan (TAMP) required under the Moving Ahead for Progress in the 21st Century Act (MAP-21).

TDOT will also consider additional tasks in following up on the vulnerability assessment.

  • TDOT has already identified slopes near roadways that are most vulnerable to rockslides, TDOT will combine this information with the data regarding locations of expected increased precipitation, to help select priority sites for potential slope stabilization projects.
  • Based on the more detailed assessment of critical transportation assets, TDOT will identify additional adaptation projects for possible addition to the State's Transportation Improvement Program (TIP. TDOT would need to determine how to evaluate adaptation projects against congestion relief projects. This would likely require quantifying the benefits of implementing adaptation projects.
  • TDOT will consider issues associated with whether and how to modify repair and replacement standards so that facilities may be upgraded to a more resilient condition.
  • Developing linkages throughout TDOT and with other transportation agencies (e.g., MPOs) to address extreme weather more effectively.

Lessons Learned and Advice to State DOTs

A statewide vulnerability assessment is an ambitious project and required a significant commitment of time and resources; however, the project results served as a vital screening tool that can be used to determine where best to focus a more detailed study to determine what, if any, adaptation measures might be warranted. For example, the statewide study required grouping assets into classes, such as “roads,” but this approach has substantially limited the number of roads in the state that warrant a further review, a review which will allow more unique characteristics of the asset to be evaluated to determine vulnerability, such as pavement binder, age of the road, and more.

Another lesson learned is the importance of local stakeholder knowledge and input. The project conducted regional meetings across the state and were able to get a much better understanding of what assets and routes are considered critical, or not, from a local perspective. Local knowledge of how assets perform during extreme weather events was also vital to the study. TDOT field staff already have a great deal of knowledge of regional vulnerabilities that were relevant to the study.

More details on the study are available in the pilot project final report. A summary of the TDOT pilot is provided in an FHWA Webinar Recording.

Case Studies: Vermont - Vermont Agency of Transportation Expands Emphasis on Managing Roads in Concert with Streams and Rivers

In the wake of the devastating floods wrought by Tropical Storm Irene in 2011, the Vermont Agency of Transportation is working to expand training and awareness on how to properly manage highway infrastructure in concert with the natural ebb and flow patterns of the state's river systems.

Irene's torrential rains and flooding washed out or damaged hundreds of miles of roads and hundreds of bridges and left entire communities stranded. In its wake, Irene also taught an important lesson: the need to manage the state's road infrastructure to be more compatible with its streams and rivers.

Irene's devastating floods "changed the way we do business in Vermont,” according to VTrans Deputy Secretary Rich Tetreault, who served as the agency’s Director of Program Development and Chief Engineer.

Tetreault said VTrans employees are being sent back to the classroom for coursework on the science of rivers. Also known as "fluvial geomorphology," this science stresses how natural cycles of periodic flooding and deposition allow river systems to reach a balanced state known as "equilibrium." Both online and classroom training is available. The contents, which are grouped into three tiers ranging from basic to advanced, have been developed by engineers at the Vermont Agency of Natural Resources.

Managing for Equilibrium

The Tier 1 training - which also is used by ANR for its own staff – is an online self-guided basic course that describes the value of rivers and hydrologic and sediment regimes; explains river behavior, including river morphology, river equilibrium, and channel evolution; discusses rivers and human development, including flood and erosion hazards and efforts to control rivers; and explains how best to manage rivers for equilibrium.

The course summarizes the following key points about river processes and management:

  • Rivers have a natural level of stability that is realized when the power of the river flow is in equilibrium with the sediment load.
  • This balance can be tipped when activities on the landscape or in the river change the amount of flow and sediments delivered to the rivers and/or the power created by the flow and resistance provided by the river channel.
  • When the balance is tipped, the river enters a disequilibrium condition and potentially a channel evolution process and the threat to property and developments is increased.
  • Working with the natural tendencies of rivers to manage for equilibrium is the most cost effective way to reduce river related damages and threats to public safety.

The training helps professionals learn how to better identify areas with severe erosion hazards, how best to mitigate areas where damage has occurred, and how to better design roads and features to avoid future damage. It is applicable to a range of transportation professionals including engineers, technicians, equipment operators, and highway foremen.

"This goes from the hydraulics engineer to the bridge and roadway designers, to the local road foreman and the excavator operator that's working in the river, so they all better understand the dynamics of the river when they are working on public infrastructure," Tetreault said. At the same time, the training is being provided to local agency partners and contractors.

The Tier Two training is a classroom and field-based training that delves more deeply into the topics of physical river processes, aquatic habitat and the interactions between rivers and adjacent infrastructure. It also explains the permitting process and standards that must be met. Emphasis is placed on accommodating stream equilibrium, avoiding practices that trigger further instability, and minimizing impacts to aquatic habitat during emergency flood response and recovery operations when technical support is not available. Contents are particularly geared toward design, construction, maintenance and planning professionals.

It includes “a lot of hands on work, both in the classroom with custom built flumes and in the field, knees deep in a local stream,” said Scott Rogers, VTrans Director of Operations. “We have mandated some of our folks from the maintenance garages attend Tier 2 to become more intimately familiar with the dynamics of the systems. They are the ones running the equipment (or making the decisions on repair work) in the field,” he added.

In 2015, the Tier 2 format was modified slightly to mix participants from VTrans with those from municipalities. In addition, a special training was held for regional planning commission transportation planners and another for private sector engineers. Mixing participants allowed for state-municipal dialogue that resulted in technical transfer and the development of greater appreciation for differing perspectives.

The Tier 3 training currently is under development, with completion scheduled for spring 2016 and training sessions to begin near the end of 2016. Tier 3 will focus on advanced engineering and construction oversight topics, specifically the design and construction oversight of the stream alteration practices outlined in the Vermont Standard River Management Principles and Practices document (2014).

Codifying the River Science Approach

In addition to offering the training courses, VTrans has updated its hydraulics manual to codify the "river science" approach. While the previous manual was based on the hydraulic capacity of infrastructure – focused strictly on water – the revised manual also considers sediment and debris.

The new manual allows for more risk-based design in terms of roadway safety and stream stability. It also corresponds to VTrans' latest stream alteration permit, codifying a process that currently is required under permit but not recognized as a standard by authorities such as the Federal Emergency Management Agency (FEMA).

"The new manual doesn’t change the hydrologists' methodology. It codifies it such that when FEMA comes to town we will have another documented standard to fulfill when they are replacing public infrastructure," Tetreault said.

For example, where slope repairs are needed adjacent to rivers, workers historically had dumped stone down the slope, further constricting the river channel. Such repairs now would start with defining the stable channel dimensions for the river and then building the slope to match - all with the help of fluvial geomorphologists. "Across the board, we are really making this part of our standard operating procedure," Tetreault added.

Understanding River Systems

Tetreault said that the "river science"-based approach is important for all ongoing activities of maintaining existing infrastructure, up to and including reconstruction or new construction of highways. For example, such considerations are important when addressing a culvert replacement or a slope failure or a river channel that needs some adjustment to respond to the built environment around it.

"There is a dynamic going on continuously with the rivers, and there is maintenance going on with drainage systems or even the river itself. People need to be aware of the fact that the river is working and we need to work with it and understand the changes that occur over time," he said. "So the minute you get an excavator out and you're working near a river, stop and think: if I put this rock here or if I remove this tree trunk here, what is it doing to the dynamics of the river as it is now and will be in the future?"

Tetreault said other states with river systems could benefit from the self-administered training course, which is posted online and is free of charge. The Tier 1 training course can be accessed online.

Case Studies: Colorado DOT - I-70 Mountain Corridor Project CSS Process

A collaborative process to ensure broad stakeholder involvement and consideration of environmental as well as community concerns has proven to be a key element in advancing a suite of multi-modal solutions for the Interstate 70 Mountain Corridor in Colorado.

On March 11, 2011, the Colorado Department of Transportation announced completion of the final Programmatic Environmental Impact Statement (PEIS) for a range of improvements to the 144-mile I-70 Corridor, a vital east-west interstate connection west of Denver and across the Rocky Mountains. This was the agency’s second attempt at a solution for the corridor, after a previous draft environmental document generated public opposition.

The PEIS is a Tier 1 NEPA document that looks at a variety of solutions for the corridor. The preferred alternative – which was developed through wide-ranging stakeholder collaboration – includes a menu of short-term and long-term multi-modal highway and transit solutions to improve transportation through the corridor, while incorporating numerous agreements for consideration of natural resources, wildlife habitat, historic resources, and community concerns.

The preferred alternative identified in the document includes three main elements: non-infrastructure components that can begin in advance of major improvements; an advanced guideway system (AGS) element that is dependent on further study and funding; and a range of highway improvements. The alternative is to be implemented in stages, ranging from a minimum program of local transportation improvements that can be addressed in the shorter term, to a maximum program of improvements – including potential for AGS – to meet projected capacity needs through 2050.

Stakeholder Collaboration

The preferred alternative is the product of years of collaboration among multiple stakeholders working alongside CDOT to identify transportation solutions to address growing congestion and projected future demand for travel along the corridor. It was developed by a group known as the “Collaborative Effort” – including representatives from local governments; highway users; and transit, environmental, business and recreation interests; as well as state and federal agencies.

Governor Signs the Collaborative Agreement

The Collaborative Effort team worked in conjunction with another group of stakeholders who were focused on incorporating CDOT’s commitment to context sensitive solutions as part of the corridor project. As part of that effort, CDOT worked in cooperation with seven counties; 27 towns; two National Forests; one ski corporation; six ski resorts; and thousands of residents, business owners, truckers, and commuters. The group developed a Context Sensitive Solutions Guidance that was used in developing the PEIS and will be followed for all future (Tier 2) projects in the corridor.

The CSS Guidance includes a commitment to form collaborative “Project Leadership Teams” on all corridor projects. For the Corridor PEIS, the Project Leadership Team formed task forces to address cultural resources issues, environmental issues, and community value issues. The task forces developed potential mitigation strategies for impacts to resources for incorporation into the PEIS.

Several memoranda of understanding and agreements were adopted outlining commitments, including:

  • A Landscape Level Inventory of Valued Ecosystem Components (ALIVE);
  • Stream and Wetland Ecological Enhancement Program (SWEEP); and
  • Section 106 Programmatic Agreement for consideration of historic resources.

Comprehensive CSS Guidance Website

The CSS Guidance for the corridor is housed on a comprehensive, interactive website. The site includes a context statement and core values developed by the CSS team, outlines the collaborative decision-making process to be used, and includes background information, maps, plans and legal commitments, as well as additional tools to implement CSS throughout the corridor.

The CSS Guidance also provides design guidelines, including overarching principles as well as more targeted engineering design criteria, areas of special attention, as well as aesthetic guidance to ensure a consistent vision for the corridor projects.

Case Studies: Florida DOT - Florida DOT Develops Traditional Neighborhood Development Handbook to Integrate Design Flexibility and Context Sensitivity

The Florida Department of Transportation has used the Traditional Neighborhood Development approach to help communities integrate land use and transportation to achieve increased livability when compared to Conventional Suburban Development, or “business as usual.”

For state DOTs, the challenge to transition from Conventional Suburban Development to Traditional Neighborhood Development often arises when the roadway standards engineers are required to meet for state roads do not provide the flexibility needed to design context sensitive solutions.

Traditional Neighborhood Development typically includes a range of housing types, a network of well-connected streets, public spaces, and a variety of amenities within easy reach of housing.

In 2001, recognizing the need for greater flexibility in design and engineering standards to pursue Traditional Neighborhood Development solutions for communities, Florida revised its “Manual of Uniform Minimum Standards for Design, Construction, and Maintenance for Streets and Highways” (last rev. 2013), commonly known as the “Florida Greenbook.”

The addition of Chapter 19, Traditional Neighborhood Development, in 2011 to the Florida Greenbook formalized the state’s endorsement of context sensitive approaches to transportation and land use as standard practice. Chapter 19 focuses on network functionality and design standards that support communities. To supplement Chapter 19 and describe the why and how of Traditional Neighborhood Development, Florida DOT published the “Traditional Neighborhood Development Handbook” (2011) providing best practices and facilitating proper design for communities.

Though Florida DOT maintains Chapter 19 and the Traditional Neighborhood Development Handbook, implementation is at the local level. The Florida Greenbook was produced through committees made up of local representatives (e.g., public works directors, consultants, and engineers) while the Traditional Neighborhood Development Handbook was developed over time by experts. The two documents work together to implement the approach.

Lessons Learned

FDOT officials have identified the following key lessons learned from their Traditional Neighborhood Development efforts:

  • Balance: It is not easy to balance building state DOT roadways with the needs of the places those roads runs through. Having an established program that supports Traditional Neighborhood Development allows state DOTs to build roads and provide transportation, while simultaneously supporting communities to survive and thrive along roadways.
  • Justification: Standards like Chapter 19 and guidance like the Traditional Neighborhood Development Handbook help provide justification and backup for decision-making, such as when an engineer or lawyer needs clear direction on what is supposed to be done and can be done in a given situation. It is important to have roadway standards that match Traditional Neighborhood Development for successful implementation.
  • Economic Development: Realizing the potential for streets as economic development. Traditional Neighborhood Development is how you build roads that make money for your community, not just roads that move money through your community.
  • Barriers: Without Chapter 19 or the Handbook, many attempts at Traditional Neighborhood Development were running afoul of existing standards. It can be onerous for an engineer to have to apply for design exceptions every step of the way. With Traditional Neighborhood Development in the Florida Greenbook, the pathway is smoother.
  • Context: Providing Chapter 19 and the Traditional Neighborhood Development Handbook is one way a state DOT can show it understands the issue of context and encourage communities to consider the issue of matching streets to land use to create complete streets.

There is a common belief that roadway engineering standards are entirely based on safety (e.g., “a 12-foot lane is safer than 10-foot lane”) and apply to all conditions, and that deviations are unsafe. As a result, the flexibility that Chapter 19 and the Traditional Neighborhood Development Handbook provides may be initially received with skepticism by engineers and other community stakeholders.

To help stakeholders learn about the benefits of this flexibility, DOTs and local communities benefit from continued dialogue and discussion to understand the advantages of Traditional Neighborhood Development and to gain support and buy-in at all levels. Working through the changes together with emergency response, public works, and other local government stakeholders builds trust. The collaboration informs state DOTs about where locals are coming from and demonstrates that the state DOT is looking out for their interests.

“The Traditional Neighborhood Development Chapter and Handbook let folks build safe, complete, walkable streets that are normally difficult to do under conventional standards,” said DeWayne Carver, Florida DOT’s Chapter 19 technical expert. “If you want to encourage and permit traditional neighborhood development (new or old), then you need thoroughfare standards to match. The TND standards can help us save the great urban places we have in our state by putting the right roadway design in the right place.”

Current Efforts and Next Steps

Like Florida, other state DOTs are also embracing Traditional Neighborhood Development. North Carolina DOT has TND Street Design Guidelines and Massachusetts DOT completely rewrote their guidance for their entire department and highlights Traditional Neighborhood Development case studies in an online toolbox. Others, like Mississippi DOT and Vermont DOT, are implementing complete streets policies and moving towards similar programs.

At Florida DOT, officials have met with internal and external partners to determine what needs to be done differently to implement a complete streets policy. This will likely include a change in state standards to more closely align with Chapter 19 and the Traditional Neighborhood Development Handbook for locations that can use the approach.

The Florida DOT recognizes that Chapter 19 and the Traditional Neighborhood Development documents will soon be ready for revisiting, especially once Florida state standards are updated with complete streets policy. Committees that include local representatives will again be involved early to discuss and implement any needed updates to the Handbook.

Case Studies: Washington State DOT - WSDOT Looks to Practical Solutions for Flexible, Sustainable Projects

A new, more practical approach to transportation project design is helping the Washington State Department of Transportation (WSDOT) complete one of the largest capital improvement programs in its history.

“We are transforming our approach to focus on finding practical transportation solutions,” explained Nancy Boyd, WSDOT’s Director of Engineering Policy and Innovation. “Our goal is to fix more problems, system-wide. The approach is similar to FHWA’s Performance Based Practical Design (PBPD), but broader in scope, encompassing asset management and operations in addition to planning and design.”

Practical roundabout solution: Photo: WSDOT

Practical Solutions entails focusing first and foremost on the need for the project, rather than simply existing standards and how to meet them. Agency staff members are being empowered to think both pragmatically and creatively to come up with smart solutions using the growing body of data and technology tools available to them.

Boyd said the focus on PBPD, which her agency calls Practical Solutions, began in 2013 as part of a broader reform process instituted by the state’s transportation secretary.

For her agency, Practical Solutions is a two-part strategy that includes both least cost planning and practical design. The focus on project purpose and need is sustained throughout all phases of project development: planning, program management, environmental analysis, design, construction, and operations. The ultimate goal is to enable more flexible and sustainable transportation investment decisions.

While cost-effectiveness is a cornerstone of the approach, so is community engagement and interdisciplinary, collaborative decision-making. Local stakeholders are being engaged at the earliest stages of defining the project scope to ensure their input is included. Project design is based on the larger context – both land use and transportation requirements. The approach does not mean compromising safety, environmental compliance, or standards.

“Expanding our focus to also include planning and asset management offers especially promising opportunities,” Boyd said.

To build transparency and accountability into the process, WSDOT is required to report annually on the results of its Practical Solutions approach, including cost savings. Under the terms of the legislation, these cost savings will be put into an account that then can then be reinvested on a new set of needs, starting in 2024.

Boyd cited numerous Practical Solutions benefits besides the cost-savings. First of all, she said, engineers can be more creative when the project focus is on coming up with smart solutions. In addition, early engagement with the public helps make customer needs an early foundation of the process. And the emphasis on least cost planning helps to avoid overbuilding. It also opens up possibilities for more, smaller projects that allow for recent advances in technology to be harnessed as they unfold.

For instance, the agency reconfigured an interchange to improve connectivity and accommodate the size of vehicles using it. Annual maintenance costs were reduced by $12,500 by eliminating stop lights, and the final roundabout design avoided costs of up to $24 million compared to other alternatives.

In another instance, to cut down on accidents from speeding along a winding two-lane highway, wider pavement striping was installed to provide the appearance of a narrow road (which slows speeds} and additional reflective centerline raised pavement markings were added. The change in approach reduced the need to change the roadway prism and saved an estimated $50,000.

Ongoing Process

To help the Practical Solutions approach become ingrained, the agency’s Design Manual is undergoing major changes. Greater emphasis is being placed on multimodal solutions, demand management planning methods, operational changes rather than new construction, and off-system strategies that offer alternatives to automatically rebuilding. In addition, planners are turning more often to incremental solutions rather than always designing “all-in-one” projects. And context-sensitive solutions are becoming institutionalized even more than before.

In September 2015, the agency created a Practical Solutions Committee. It serves as a forum for learning and sharing how to deliver at the lowest costs as well as encouraging innovation and creativity in design. The committee is composed of WSDOT leadership team members as well as members of program offices, modes, and regions. It also includes representation from the Federal Highway Administration.

One of the committee’s primary responsibilities is to carry out a multidisciplinary review of its Connecting Washington funding package to identify every opportunity to embed a Practical Solutions approach. Connecting Washington funding goes to finishing projects in key corridors to preserve infrastructure and reduce congestion; improve freight mobility; support multimodal transportation options; and address critical needs for bridges.

Meanwhile, FHWA continues to do its part to advance PBPD. It has issued a final rule to reduce the number of “controlling design criteria” on highways designed for speeds of less than 50 miles per hour (mph) from the current 13 down to 2. For roads with “design speeds” greater than 50 mph, the number of criteria has been reduced to 10. It also has issued a final rule to update design standards applicable to National Highway System projects. And it has updated its guidance on bicycle and pedestrian facilities to provide greater opportunity for including these options in project design.

Handling Possible Risks, Other Insights

WSDOT is not the only state DOT that is turning to a PBPD-type approach: the practice is alive and well in Missouri, Kentucky, and Kansas, and approximately 30 additional states are implementing or planning to implement it in some form.

And yet, implementation is not without risk, including the risk of tort lawsuits arising from crashes alleged to be associated with a roadway design; and the risk of the solution not performing as expected in terms of safety and operations. To address potential risks, WSDOT consulted with agency risk management and attorney general staff and were reassured that exercising good engineering judgement is preferable and more defensible that blind application of “standards.”

Implementation of a Practical Solutions approach also presents some challenges. One has been a lack of sufficient funding for training. In addition, the agency has had to keep close watch on evolving environmental considerations, the political process, emerging tools for design and safety analysis, and the constant push for regulatory reform, any of which could affect the approach.

WSDOT has learned some lessons along the way that may be useful to other state DOTs, according to Boyd. First, the cookie cutter approach to project design is obsolete. Second, collaboration improves the quality of project’s effect on the multimodal transportation system; learning together and sharing information builds trust. Third, gaining political support for practical solutions to transportation infrastructure is essential. And finally, small fixes can make big differences.

Looking Ahead

Besides updating the Design Manual, the agency will be giving greater priority to training planning and design staff in the months ahead. Subject areas will include practical solutions/project development process training, multimodal design training, and Highway Safety Manual implementation. Further down the road, least-cost planning and cost estimating for alternatives analysis will be added.

Boyd said that her agency recently received $16 billion in new funding for additional capital improvement projects over 16 years, and implementing Practical Solutions will be an essential component of that work.

“Using the creativity and innovation of Practical Solutions, we are developing a safer and better transportation system while making our funding go further and accomplish more,” she said.

Case Studies: Ohio DOT - Ohio DOT Provides Step-by-Step Guidance for Environmental Justice Analysis

As environmental justice in infrastructure planning and construction continues to be promoted at the federal level, state transportation agencies are finding ways to make the process more defined for staff and consultants.

At the Ohio Department of Transportation, recent revisions to the agency’s environmental justice guidelines update the agency’s procedures with a focus on clarifying the extent of analysis needed for projects and environmental reviews in the state.

The ODOT Environmental Justice Guidance uses a step-by-step format to explain what practitioners must do to comply with state and federal environmental justice requirements.

The steps include identifying environmental justice populations within the study area using a mapping tool, answering a series of questions to determine whether a full-scale environmental justice analysis report is required, and if required, conducting the analysis and report as outlined in the guidance.

EJ Process in Ohio

Environmental justice has been a part of the conversation with regard to transportation projects for at least two decades.

Environmental justice populations—specifically minority and low-income groups—can be disproportionately impacted by transportation projects, and these impacts can vary depending on a project’s scale, scope and location, according to Erica Schneider, Assistant Administrator with ODOT’s Office of Environmental Services.

Like all state transportation agencies, ODOT developed its environmental justice program in response to Title VI of the Civil Rights Act, Presidential Executive Order 12898, Department of Transportation Order 5610.2, and FHWA Order 6640.23A.

ODOT’s environmental justice procedures resulted from many months of work with the Federal Highway Administration’s Ohio Division, Schneider said. “It was a collaborative process that took several months of discussions and a fair amount of compromise,” Schneider said. Once the division office was comfortable with it, ODOT worked with FHWA headquarters and Resource Center, she added.

Identifying EJ Populations

ODOT’s guidance uses a tiered method to evaluate environmental justice considerations. The first step relies on the Environmental Protection Agency’s EJScreen web-based tool, which places U.S. Census population data on a map at the block and block group levels. Block groups are clusters of blocks within the same census tract, generally defined to contain between 600 and 3,000 people, used to present statistical data and control block numbering.

According to the guidance, the individual performing the analysis under the National Environmental Policy Act (NEPA) uses EJView to locate the project or study area and, using the data filters, identifies the percent of minority or low income residents.

“Project [area] limits are identified by earlier studies (traffic, safety, etc.) that define the purpose of the project,” Schneider said. “Those limits in turn help identify the block groups that could be impacted by a project and by the activities associated with the project.”

The key threshold for environmental justice populations is 40 percent, according to the guidance. “If all of the block groups within your proposed project area indicate Environmental Justice populations below 40%, then no additional Environmental Justice analysis or coordination is required,” the guidance said.

However, if either the minority or the low-income populations are at 40 percent or above, the practitioner is required to answer a set of questions to determine potential impacts.

Determining Potential Impacts

The questions in the guidance make a decision tree that leads the practitioner to draw conclusions about whether the project will have a disproportionately high and adverse effect on the target populations.

“Our guidance is, in many ways, a screening tool to screen out projects with little to no potential to impact EJ communities,” Schneider said.

“The questions in the guidance are specifically geared toward identifying potential impacts,” Schneider said.

For example, the questions address the following issues:

  • Are there any relocations?
  • Will there be any changes to access?
  • Were any environmental justice issues that could result in a disproportionately high and adverse effect raised during public involvement?
  • Are there any other unique factors of the proposed project that could pose a disproportionately high and adverse impact on an environmental justice population?

Depending on the resulting answers, a full Environmental Justice Analysis Report may be required.

Conducting Full Analysis, Report

When a full analysis is required, a report is prepared “to determine whether or not your project will have a disproportionately high and adverse impact to an Environmental Justice population and to document any avoidance and mitigation measures,” the guidance said.

The guidance provides a general outline of what information should be included in the report. The seven basic elements include:

  1. Project description;
  2. Summary of purpose and need statement;
  3. Discussion of environmental justice populations;
  4. Discussion of impacts to environmental justice populations;
  5. Public involvement summary;
  6. Discussion of avoidance, minimization and mitigation measures; and
  7. A summary, including justification for the determination.

For projects that require in-depth analyses, the guidance urges users to work with ODOT’s Office of Environmental Services, Policy and Cultural Resources Section for more direction and project-specific assistance on determining how to address potential impacts.

Guidance Applies to NEPA Process

The ODOT guidance must be followed for all environmental assessments, environmental impact statements, and most categorical exclusion levels under ODOT’s 2015 Programmatic Categorical Exclusion Agreement.

Although the guidance is built into ODOT’s Online Categorical Exclusion System, the environmental justice process is essentially the same for more complex environmental documents, according to Schneider, except that “the documentation part is a little different.”

Projects requiring an environmental assessment or environmental impacts statement “often have a higher potential for impacts, but not necessarily,” Schneider added.

Schneider said that less than 1 percent of projects per year require a full Environmental Justice Analysis Report. But for those projects that may impact environmental justice populations, the guidance encourages staff to coordinate with ODOT’s Office of Environmental Services “as early as possible.”

Lessons Learned

Schneider noted several lessons learned in developing the process.

“We strongly emphasize a common sense approach to looking at projects,” Schneider said. “If it makes sense to look farther out [from the project boundaries], we would do so.” Regarding the decision to rely on the EJView tool, it was the result of a lot of work with FHWA division staff and EPA staff, according to Schneider. “We didn’t find a better tool to use,” Schneider said. She recommends use of EJView to other departments of transportation, unless and until something better is developed.

Additionally, Schneider emphasized the importance of making sure the analysis is meaningful.

“We constantly remind our staff and consultants that you can’t just go through the motions,” Schneider said. “Simply having less than 40 percent EJ populations or answering ‘no’ to all of the questions doesn’t mean consideration of EJ populations ends there. We still expect practitioners to use common sense. If there are EJ populations that may require specific public outreach efforts, then that needs to be done. If EJ issues are raised during public involvement activities or there are other project-related circumstances that could cause an impact to EJ populations, those need to be taken into account and addressed.”

Schneider said the guidance has been well received both by consultants and ODOT staff. “It has streamlined our processes by helping screen out projects that don't require further work,” and to “target what we need to focus on,” she said.

Case Studies: Pennsylvania DOT - Pennsylvania DOT Develops Separate EJ Guidance for Planning, Project Levels

The Pennsylvania Department of Transportation (PennDOT) is successfully integrating input from minority and low-income populations (environmental justice [EJ] populations) and consistently documenting its EJ analyses and findings through use of planning- and project-level guidance developed by the agency.

Executive Order 12898 (1994), Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations, directs federal actions to avoid, minimize, or mitigate disproportionately high and adverse human health and environmental effects, including socioeconomic, on EJ populations. However, Executive Order 12898 did not provide guidance on how to identify EJ populations, or how to determine if impacts are disproportionately high and adverse.

EJ Guidance at PennDOT

Pennsylvania Department of Transportation’s (PennDOT) approach to implementing Executive Order 12898 (1994)—as well as subsequent Memorandum of Understanding on EJ signed by heads of federal agencies (2011) and DOT’s Final EJ Order 5610.2(a) (2012)—uses guidance documents that are distributed to districts for implementation. In addition to guidance it developed for regional planning-level EJ analyses, PennDOT, also has developed project-level guidance to promote consistency in EJ analyses conducted for relatively minor-impact projects across the state.

Two notable factors influencing PennDOT’s EJ approach include: 1) the agency is decentralized, with projects held at the district-level, and 2) around 99 percent of current PennDOT projects are Categorical Exclusions (CEs) under the National Environmental Policy Act (NEPA).

Planning-Level Guidance

Initially, PennDOT developed an EJ guidance for statewide planning and programming processes, Every Voice Counts (2004, updated 2012). PennDOT drew from best practices and existing resources proven to work in practice to develop its EJ guidance. Every Voice Counts describes PennDOT’s regional planning-level EJ responsibilities as: 1) identifying EJ population presence within planning areas; 2) engaging EJ populations in public involvement and subsequent documentation of that engagement; 3) assessing the effects of transportation policies, investments, and programs on EJ populations; and 4) avoiding, minimizing, or mitigating, as appropriate, disproportionately high and adverse effects.

According to PennDOT’s Transportation Planning Manager Brian Wall, despite the initial Every Voice Counts guidance there were dramatic differences in how EJ efforts were being conducted and documented throughout the state due to the agency’s decentralized operational structure and the number of metropolitan and rural planning organizations and the various staffing levels at those organizations. Therefore, in 2012, as a result of a strengths/weaknesses assessment, PennDOT expanded its EJ guidance and provided clear examples of how to conduct an EJ analysis at the planning level.

Project-Level Guidance

After implementing its planning-level EJ guidance for nearly a decade, PennDOT developed its Project Level Environmental Justice Guidance in 2013. The guidance provides a step-by-step EJ analysis framework to ensure requirements of Executive Order 12898 are appropriately identified, considered, and documented at the project level. Because PennDOT is decentralized, the project-level guidance provides consistency across DOT districts in their approach to EJ analyses.

Additionally, with nearly all PennDOT projects falling under CEs with minimal impacts, PennDOT Environmental Planning Manager Drew Ames said that it can be tough to document EJ efforts. The project-level guidance addresses the issue of determining the presence of EJ populations, appropriate level of documentation, and determining disproportionate adverse impacts. The guidance explains what needs to be done after a project is on the Transportation Improvement Program and preliminary engineering begins, and includes criteria that would qualify a project as exempt from a detailed EJ analysis.

PennDOT provides and documents consideration of potential impacts to EJ populations for categorically excluded projects in the on-line Categorical Exclusion Expert System. For CEs falling under 23 CFR 771.117(d), that are not otherwise covered by a programmatic agreement, the system prompts preparers to answer a series of questions regarding EJ that are based on the analysis described in the guidance document.

In addition, the project-level guidance includes several real-world case studies that describe how project teams reached out to and engaged EJ populations, what data were gathered and analyzed to determine if EJ populations are located in the study area, and what project impacts and benefits were evaluated to determine if the project caused disproportionate and adverse impacts to EJ populations. Moreover, the case studies include helpful “lessons learned” so that other EJ analyses are informed by past experiences. Examples of lessons cited in the guidance include the following:

  • While review of demographic data helps to identify the presence of EJ populations, field views and discussions with local stakeholders can provide valuable insights that cannot be drawn from review of demographic data alone.
  • Enlisting EJ community representatives on community advisory committees can help gain the EJ community’s trust and support for a project.
  • The study area size and shape may require information to be collected from a variety of census data geographies, and may impact the level of effort and resources needed for data collection.
  • Project teams should always check their assumptions about adverse impacts by discussing impacts with EJ populations. What might be considered an adverse impact by project engineers and planners may or may not be interpreted as adverse by the community.

Key Takeaways

PennDOT has realized the following key points and lessons learned in implementing the agency’s planning- and project-level EJ guidance:

  • Documentation: Regardless of a project’s size, it is important to state clearly what types of information or data were considered to identify the presence of EJ populations (e.g. Census data), how EJ populations were engaged in project scoping and the development of project alternatives and any mitigation measures, and how project design may have changed as a result of input from EJ populations.
  • Balance: An EJ analysis is never a “one size fits all” analysis. It is location, community and context-driven, based on the project’s direct, indirect and cumulative impacts and how those impacts are experienced by EJ populations, both positively and negatively.
  • Process efficiencies: Providing a unified guidance for application across jurisdictions helps streamline the state’s EJ analyses and documentation. For example, the process outlined in Every Voice Counts has led to better “benefits and burdens” analysis in long range transportation planning, particularly through the use of GIS.
  • Consolidation: The guidance is intended to consolidate the wealth of information into a document that is easy to access and use for replication across the state—and for other state DOTs.
  • Context: Familiarity with a project area and its residents is irreplaceable. Taking the extra step—such as proactively speaking directly with a community—creates opportunity for more meaningful engagement, a better informed EJ analysis and proactive issue resolution promoting a more collaborative decision-making process.

Overall, PennDOT’s implementation of both its planning-level and project-level EJ guidance documents has enhanced the agency’s ability to integrate meaningful input from EJ populations into its plans, programs, and projects, and has allowed the agency to consistently document its EJ analyses and findings.

Case Studies: Washington State - WSDOT Reports Significant Time Savings by Issuing Combined EIS, Record of Decision

Provisions of the Moving Ahead for Progress in the 21st Century Act (MAP-21) that allow environmental impact statements and record of decision documents to be combined for transportation projects have achieved significant time savings for Washington State DOT, according to the agency.

The authority to issue one combined document have saved approximately 60 days to 90 days for the first two projects for which the agency used it, state officials report.

The authority was enacted as a streamlining provision under Section 1319 of MAP-21. In addition, the law authorized use of errata pages rather than a separate standalone final EIS if only minor comments are received on a draft EIS.

The provisions of MAP-21 were aimed at cutting the time required to process environmental documents for transportation projects.

WSDOT has published two combined FEIS/RODs under the new law: a Final Supplemental EIS and Record of Decision for the I-90 Snoqualmie Pass East project, and a Final Supplemental EIS and Record of Decision for the SR 167 Puyallup River Bridge project, according to WSDOT Policy Branch Manager Carol Lee Roalkvam.

For both projects, the combined EIS/ROD eliminated one round of document circulation and streamlined the cooperating agency and legal review. Each project saved approximately two to three months’ time, she said.

Additionally, the I-90 project team used the related streamlining measure which allows for a Draft EIS and errata page to suffice for a final EIS.

The I-90 team noted that the new processes used together took less time that it would have taken to prepare an Environmental Assessment/Finding of No Significant, according to Roalkvam. In one year, the team went from notice of intent, to Draft Supplemental EIS, to Final EIS/ROD.

“Many state DOTs are searching for examples of quality environmental documents,” Roalkvam said. “While every project is unique, I encourage state DOTs to look at the way the I-90 team applied the MAP-21 streamlining provision and the abbreviated FEIS format to prepare a concise, complete and readable document.”

Combined FEIS and ROD

Prior to MAP-21, FHWA and FTA were required by their own regulations and Council on Environmental Quality regulations to provide a waiting period of at least 30 days between publication of the FEIS and issuance of the ROD.

Section 1319(b) of MAP-21 overrode that requirement. It directs the lead agency to issue the FEIS and ROD as a single document “to the maximum extent practicable,” unless one of the following conditions is met:

  • the FEIS makes “substantial changes to the proposed action that are relevant to environmental or safety concerns” or
  • “there are significant new circumstances or information relevant to environmental concerns and that bear on the proposed action or the impacts of the proposed action.”

FHWA and FTA issued interim guidance implementing Section 1319 on Jan. 14, 2013. The interim guidance calls for a case-by-case determination as to whether it is “practicable” to issue a combined FEIS and ROD. The guidance also directs FHWA Division Offices and FTA Regional Offices to consult with headquarters before issuing a combined FEIS/ROD.

‘Errata Pages’ Format for FEIS

MAP 21 also clarified that the lead agency can issue an FEIS that consists of “errata pages” -- rather than a complete, stand-alone document -- if the agency received only “minor comments” on the Draft EIS.

This flexibility existed under the CEQ regulations even before the enactment of MAP-21. Section 1319(a) confirms that this format is acceptable.

It also requires that errata pages “(1) cite the sources, authorities, or reasons that support the position of the agency” and “(2) if appropriate, indicate the circumstances that would trigger agency reappraisal or further response.”

In the Jan. 14 guidance, FHWA and FTA described the information that should be included in errata pages, and confirmed that this documentation must undergo the legal sufficiency review required for an FEIS under 23 CFR 771.125.

Case Studies: Virginia - Virginia DOT's Environmental Data and Reporting System Improves Communication, Accountability

The Virginia Department of Transportation’s (VDOT) evolution to an environmental data management system started with more than 73 decentralized spreadsheets and personal databases. In 2001, VDOT developed its GIS Integrator, an internal geographic information systems (GIS)-based tool to support the agency’s efforts to improve early project development and environmental review by capturing a spatial inventory of project shapes used to identify existing environmental resources with the potential for project impact through spatial analysis.

In 2003, VDOT expanded their data management solution by consolidating all non-spatial data sources into an environmental data repository called the Comprehensive Environmental Data and Reporting system (CEDAR). This internal web based application provides a single user interface for capturing all VDOT’s environmental business data, including National Environmental Policy Act (NEPA), permitting, and environmental contracts. The CEDAR application synchronizes nightly with the agency’s project pool and active directory databases for improved management of project data and user accounts. It also links to the agency’s GIS Integrator, which allows for streamlined project reviews.

“The CEDAR system provides VDOT staff with an invaluable comprehensive environmental data management tool that has successfully improved communication and accountability, said Geraldine Jones, VDOT CEDAR Administrator. “Since its deployment in 2003 CEDAR has been the backbone of VDOT’s environmental operations. CEDAR’s success, usability, and permanence can be attributed to its user championed platform and staff dedicated to maintain and enhance an application subject to dynamic regulations and processes,” she said.

The GIS Integrator allows users to buffer project shapes to determine potential resource issues. In this case, the project shape was buffered 2 miles for conservations lands. Source: VDOT

The integrated CEDAR system centralizes where staff enter and retrieve data for all VDOT’s environmental activities on a project-by-project basis, allowing for restricted viewing and editing based on roles and permissions. It captures project history, handles all project types – including construction and maintenance – tracks project status through the life of the project and generates system alerts.

The system also:

  • stores, manages and distributes documents;
  • contains a task assignment function;
  • tracks commitments;
  • documents project details such as meetings and phone calls using the journal feature;
  • contains links for environmental permit tracking and houses regulatory agency correspondence;
  • links to VDOT’s Integrated Project Manager (IPM) system, which contains project pool information;
  • links to the GIS Integrator, which allows for digitizing project shapes and spatial analysis functionality to identify environmental impacts in a project area;
  • includes both standard and ad-hoc project reporting such as new projects, tasks schedule, and advertisement schedule; and
  • provides access to project contract and other administrative information.

Benefits of the system include increased project accountability, satisfaction of mandates, and interagency coordination. It also provides documentation for decisions, and offers a tool for communication of commitments, project status, accuracy of project estimates, and efficiency of projects.

Current Efforts and Key Take-aways

Today, VDOT’s CEDAR and GIS Integrator applications are positioned for upgrades. A user advisory committee has been formed to identify functional requirements. The upgrade is expected to come with an updated user interface and be launched within the foreseeable future.

Key motivators for an integrated environmental data management system as exhibited by VDOT’s CEDAR and Integrator include the following:

  • Economic savings: Compared to “pre-CEDAR” 2003, VDOT environmental projects in 2011 experienced notable time savings. For example, the labor hours required to complete tasks associated with a project categorical exclusion (such as a biological assessment, state environmental review, or field survey for endangered species) decreased between 33 and 50 percent.
  • Process efficiencies: CEDAR consolidates applications (project management, GIS, data storage) and makes it easier to document environmental decisions and communicate environmental commitments and project status.
  • Quality control improvements: CEDAR provides standardized spatial data and pre-approved data schemes. It provides a basis for program management and trend analysis.
  • Interagency coordination and relationship building: CEDAR helps streamline interagency coordination by supporting compliance with mandates, reducing the time required for advancing projects through regulatory approvals, compiling all external agency communication, providing transparency of environmental data from all participating entities, and increasing the visibility of project.


VDOT is not alone in its development of an environmental data management system. Though many state DOTs still use spreadsheets, databases, paper maps, and shapefiles as data management tools, many others have developed standalone systems or contemplated environmental data management systems of their own. In August 2015, numerous state DOTs gathered in Oregon and online to discuss data management approaches in their agencies in an effort to share information and experiences across agencies.

VDOT’s advice to other DOTs interested in their own data management systems includes supporting an IT staff dedicated to application maintenance, and involving users from the beginning to confirm requirements and increase staff adoption of the system.

Historic Preservation/Cultural Resources

Recent Developments: National Park Service Funding Supports Park Infrastructure

The National Park Service (NPS) has announced the availability of more than $50 million to support maintenance and infrastructure projects at 42 parks in 29 states. The funding will be used to improve trails, roads and bridges, restore buildings, and increase visitor access to parks. The $20 million in federal funding will be added to funding from many non-federal partners. Projects will include addressing deferred maintenance on the Alluvial Fan Trail in Rocky Mountain National Park, and the development of a multi-use trail to connect the visitor center at the Gettysburg National Military Park to a historic farm. Funding also will be used for maintaining and improving trails, retaining walls and overlooks at the Grand Canyon of the Yellowstone in Yellowstone National Park.

Recent Developments: FTA Issues Historic Context Report for Transit Rail System Development

A report documenting the historic context for rail transit projects in the U.S. has been issued by the Federal Transit Administration. The analysis will be used by the FTA in support of an exemption from historic preservation reviews for railroad rights-of-way used for transit. The exemption would relieve federal agencies from requirements to review of the effect of undertakings on railroad rights-of-way under Section 106 of the National Historic Preservation Act. The nation’s most historically significant resources would be excluded from the exemption. The exemption is required under by Section 11504 of the Fixing America’s Surface Transportation Act (FAST Act). For more information, link to the Historic Context Report. (6-15-17)

Recent Developments: NTHP Launches New Tool That Explores Urban Built Environment

The National Trust for Historic Preservation has launched a new research tool, Atlas of ReUrbanism, that provides data currently available about cities to explore the connections between the physical character of urban development and a range of economic, social and environmental outcomes. Initial findings of the tool found that in New York City, blocks with older, smaller, mixed-age buildings have more racially and ethnically diverse populations, more than twice as many jobs in small businesses, and nearly twice as many women and minority-owned businesses. The tool currently features interactive maps for the five largest American cities, with plans to eventually include 50 major cities. For more information, link to the tool and the associated report.

Recent Developments: FHWA Highlights Louisiana’s Efforts to Identify, Preserve Historic Bridges

The Federal Highway Administration has published the November edition of the Successes in Stewardship Newsletter, which highlights the efforts of the Louisiana Department of Transportation and Development to identify, preserve and manage historically significant bridges built before 1971. The LADOTD, along with the Louisiana State Historic Preservation Office and the FHWA, signed a programmatic agreement and completed a statewide management plan which shortened the project delivery process for historic bridge projects. Historic bridges are no longer processed individually for review under Section 106 of the National Historic Preservation Act and bridge designers know in advance which bridges are committed for long-term preservation.

Case Studies: Arizona - Arizona DOT Uses Adobe Bricks to Help Restore Historic Building in Tombstone

The Arizona Department of Transportation (ADOT) has made what it calls an “architecturally challenging” decision to carry out both historic preservation work and transportation safety work in one of the nation’s most significant and infamous towns -- Tombstone.

Tombstone was one of the last frontier boomtowns in the American Old West. In its heyday, it produced millions of dollars of silver bullion and is best known as the site of the Gunfight at the OK Corral. There, ADOT is shoring up water-damaged sections of a local historic landmark called Schieffelin Hall, named for 19th century resident and silver prospector Ed Schieffelin.

“Carrying out preservation work with very unique materials alongside one of our highway projects is not what we do every day,” says ADOT Southeast District Engineer Bill Harmon.

Preservation Work

“But in this case, it was a natural fit. We were part of the scope of work for both projects. They both are being carried out in Tombstone’s Historic District. And ADOT is proud to be helping restore and preserve a treasured National Landmark.”

The unique materials Harmon is referring to are adobe bricks. ADOT is shoring up the Hall using replacement bricks that are being painstakingly produced using 19th century techniques. The fabrication process is taking place at a mine not far away in Cochise County by a crew headed up by a third-generation adobe maker. Precise historic replication will enable the new bricks to tightly weld to the remaining original bricks, thus increasing stability and also helping to fend off more water damage.

To create the bricks, wooden molds are set down and a slurry mixture of sand, silt, clay and grass is poured into the forms. After the mixture sits for a day or two and the bricks have taken shape, the forms are removed and the bricks are stacked in the sun to completely dry, a process that can take several weeks. Once the bricks arrive on site at the Hall, they are put into place and secured with a mud and straw mixture that functions like mortar. Finally, a layer of stucco is added on top to conform to the rest of the building’s façade.

Besides replacing some of the bricks, ADOT also will add a porch to the Hall to replace the original one removed in the early 1900s. Its corrugated metal roof will be supported by wooden posts, and a downspout will be incorporated to carry away rainwater.

Funding for the preservation work comes from a FHWA Transportation Enhancement (TE) grant awarded to the City of Tombstone. The TE grant was the culmination of several years of hard work involving numerous groups including ADOT, the State Historic Preservation Office (SHPO), the Tombstone Restoration Commission, the Federal Highway Administration, and the National Park Service, as well as local government, businesses, and citizens. All work is being carried out according to guidelines from the Department of Interior’s Standards for Rehabilitation, a technique required by the National Historic Preservation Act.

Safety Work

In the same neighborhood as its preservation work, ADOT also is carrying out an associated project to improve motorist and pedestrian safety along the Fremont Street portion of State Route 80 where Schieffelin Hall stands. Funding for the highway safety project comes from FHWA’s Highway Safety Improvement Program under MAP-21 and from state gas-tax dollars.

Key safety features being installed under the ADOT grant, begun in August of this year, include the following:

  • narrowing a portion of Fremont Street from 68 feet to 44 feet to make room for sidewalks and other pedestrian improvements;
  • installing landscaping and constructing sturdy concrete sidewalks that look like weathered wood to deter pedestrians from jaywalking; and
  • providing continuous street lighting throughout the area.

He continues, “Sadly, part of the impetus for installing extra rigorous safety features came from a tragic crash that took place here in Tombstone in 2009 involving two tourists. After that happened, ADOT and the city of Tombstone began to work together even more closely to implement a range of advanced pedestrian safety improvements.”

In 2010, he says, ADOT and the city of Tombstone completed a comprehensive traffic study soon after the accident. Short-term actions that ensued included road striping, parking restrictions, and reduced speed limits. The study also recommended several longer-term improvements.

Besides the key pedestrian safety features, the project also entails repaving the roadway and constructing new curbs with handicap ramps,, removing an obsolete pedestrian bridge, and installing an irrigation system for landscaping. Driveways not needed by property owners will be closed, others will be improved to meet current standards.

“Construction for both projects is moving forward steadily,” Harmon says. “Our schedule calls for completing both in the spring of 2016. The value of the two projects, combined, is right at $1 million.”


According to Harmon, while it’s not uncommon for ADOT to be involved in the preservation of historic properties through the Transportation Enhancement grants program, it is unusual for the agency to play a role in the preservation of a National Historic Landmark, including such an architecturally challenging project. As he puts it: “This project truly is one of a kind.”

Extensive collaboration took place so that both historic preservation and improved safety goals were met, he continues. The two projects were evaluated together under one NEPA categorical exclusion document. ADOT retained historic preservation specialists to help during the design and construction phases. The restoration concepts were reviewed and approved by the State Historic Preservation Officer. Detailed plans were prepared based on old photographs plus an onsite investigation of the soundness of the walls.

To meet the requirements of both Section 106 of the National Historic Preservation Act (NHPA) and Section 4(f) of the Transportation Act, AZDOT incorporated several historic preservation features. For example, to mitigate the porch’s potential impact on the historic adobe material, the design was tweaked so to have the porch be a free-standing structure rather than be attached. And the street lighting that was installed was carefully chosen in conjunction with the State Historic Preservation Office (SHPO) so as to carry forward aspects of period lighting design.

“Other state DOTs could, and may well be, carrying out similar community improvement projects under what has become the Transportation Alternatives program,” says Harmon.

“But in addition to the challenges of coordination across many different groups, there is also the issue of funding, including matching funds. We were very fortunate in this project to have both the funding and a great group of people who were willing to do what it took to make this happen.”

The project’s most memorable moment to date? Easy one, is Harmon’s reply. It was the day some cattle wandered into the brick-making area and trampled over some of the fresh adobe.

“Not a typical delay at a modern construction site,” he says, “but it probably happened more than once a century or so ago. I guess it’s to be expected when, for historic preservation’s sake, we decide to work on the cutting edge of low technology.”

Case Studies: Florida - Historic Bridge of Lions Rehabilitation

The Florida Department of Transportation was able to preserve the historically significant architectural features of the Bridge of Lions, the gateway to historic St. Augustine. Accomplished by constructing a “bridge within a bridge,” the improvement project was able to retain key elements of the original bridge while addressing the bridge’s structural problems.

The Bridge of Lions crosses Matanzas Bay (part of the Intracoastal Waterway) and connects the city of St. Augustine with the resort communities of Anastasia Island, St. Johns County, Florida. It is located in an urban setting, with its western approach in the historic district of St. Augustine. Designed by John E. Greiner and constructed in 1927, the bridge has a total length of 1,545 feet. The main span is a 95 foot double-leaf rolling lift bascule. Approach spans are steel arched girder-floor beam spans with cantilevered overhanging sections.

This architectonic bridge is a significant feature of the historic streetscape of St. Augustine and is a gateway to the old city. The bridge was rehabilitated in order to retain its historically significant architectural features, while solving the bridge’s structural problems. This was accomplished by constructing a “bridge within a bridge.” Enough of the old bridge was retained to classify the project as a rehabilitation and not new construction. New construction would have required use of all modern design criteria.

Prior to rehabilitation, the bridge was in fair to poor condition, particularly in terms of the fracture critical girder-floor beam approach spans and the substructure units. At many locations, crutch bents had been previously installed in order to provide additional support.

Rehabilitation Process

As part of the rehabilitation, the bridge’s two fascia girders were retained for visual appearance, while new steel stringers were installed inside the girders. The fascia girders, which were removed, repaired, and then reset in place, were relieved of most of the loads and the new stringers now carry the majority of the dead load and the traffic loads. The stringers are hidden from view and will not distract from the architecturally significant arched girders. In addition, the approach spans were widened in order to improve the roadway geometry.

The bascule piers and associated towers were left in place and repaired. This included replacing the existing concrete piers within the splash zone with new concrete, as the existing concrete contained high levels of chlorides. The bascule piers were strengthened by the addition of drilled shafts, and a new footing was placed below the existing waterline footing in order to provide sufficient strength for a modern design scour event.

Several features original to the bridge, but previously removed or replaced, were replicated. These included the pedestrian railing (with the height increased to meet modern standards), light standards, and rotating traffic gates. The bridge steel was painted to match the original bridge color.

The original bridge was recognized as important for its high artistic merit, rather than its technological significance. This made it possible to focus the rehabilitation on its historic character and appearance. This resulted in Florida DOT making a finding of No Adverse Effect. The Florida State Historic Preservation Officer concurred with this finding.

Lessons Learned

By retaining a sufficient amount of the existing bridge, this project was considered a rehabilitation. New construction would have required use of all modern design criteria, such as widening the navigable channel from the existing 84 foot to the 125 foot width now required for the Intracoastal Waterway.

To maintain the bridge’s historic character, it was extremely important to retain the design of the piers and the arch-shaped fascia beams, in addition to the cantilevered end sections of the girder-floor beam approach spans. The fascia girders were reused on the slightly wider stringer approach spans, supported on substructure units that were rebuilt in-kind to the new geometry. The reused fascia girders support themselves and part of the bridge’s sidewalks.

Case Studies: Pennsylvania - Pennsylvania DOT Uses ‘Story Map’ to Document History, Mitigate Impacts

The Pennsylvania Department of Transportation is using an innovative “Story Map” to share important historical information about an area impacted by a road improvement project on Route 322 in Centre County.

The online interactive map provides locations and details about historically significant sites, people, and events within the area of the Potters Mills Gap Transportation Project. Users can learn about the history of the project area and its inhabitants, including the town’s namesake James Potter, Native American settlements, log structures and historic homes inhabited by early settlers, early roads, farms, industry, cemeteries and other features. This effort to document the area’s history is part of an innovative effort to mitigate project impacts on historic resources in the project area.

The road improvement project along a section of Route 322 required mitigation for adverse impacts on several wooded tracts, historic buildings, and historic farmland areas within the Penns/Brush Valley rural historic district. The district was determined eligible for listing in the National Register of Historic Places based on its agricultural patterns, associated landscape features and Vernacular-style architecture established during the nineteenth and twentieth centuries.

The Story Map, titled A Journey to Potters Mills, is the first of its kind to be used by PennDOT to help mitigate adverse impacts to historical resources.

“The intent of the Story Map is to provide the public with insight into how the development of transportation within the Potters Mills Gap has, over time, impacted the Historic District,” said Karen Michael, PennDOT District 2 Executive.

According to a PennDOT summary, the Story Map provides visitors with a visual and geographic history of an important crossroads in the Seven Mountains region of the Commonwealth. The map “allows visitors to change scale and navigate between important historic places along the highway corridor and understand the roles that transportation, natural resources, agriculture and early industries played in the development of modern Centre County.”

The Story Map website provides an interactive map of the area with 33 separate image icons that link users to important locations – along with photos, historic maps and documents and a brief description of each. Together, the map allows users to explore the history of the region, from the time of the Native Americans and earliest settlers through various important historic events and locations.

The team sought images which spanned the development of the area, and included diverse subjects and formats including photos, historic maps, portraits, documents, and other records. Information was uncovered through research at a number of repositories, including local historical societies, universities, libraries, state agencies, and from private individuals.

Origins of Story Map Concept

The Story Map concept was proposed to PennDOT by its project consultant as a possible mitigation measure for adverse impacts identified for the project under Section 106 of the National Historic Preservation Act.

“The idea actually came from one of the consultant team members who saw a social media post that combined a map, text and images, but lacked the GIS-based interactivity of what became the Story Map,” according to PennDOT’s Steve Fantechi, who managed the project through preliminary design.

The Story Map was one of a number of mitigation measures that included roadside interpretive signage, context-sensitive design measures, the preparation of a “Best Practices” document, and avoidance and protection of some resources. The NEPA document for the project was an Environmental Assessment that concluded with a Finding of No Significant Impact.

According to Fantechi, the Section 106 consultation process involved a great deal of consultation and interaction with local historical societies and local governments. “That collaboration contributed substantially to Story Map’s popularity with local residents, the regional press, teachers, and citizens and engendered a substantial amount of local and regional pride in local heritage,” he said. “In our view that’s what a successful Section 106 outcome looks like.”

In addition, he said, the GIS-based Story Map approach also creates an obvious link between landscape, transportation networks, and economic history, which in turn promotes a better understanding of and context for historic events, trends and places.

To the best of PennDOT’s knowledge, this is the first mitigation product of its type used for an American transportation project.

Challenges and Lessons Learned

According to PennDOT District 2 staff, the biggest challenge in developing the Story Map was probably too much of a good thing.

Background research and interaction with the consulting parties produced an enormous number of images and a substantial amount of local history and documents. Paring that down to a relevant and manageable record of local and regional history was a challenge.

Once that work was done, the actual GIS programming required to produce an interactive and useable online product had its own set of challenges, as the product went through a number of iterations leading to the final version.

Another challenge came from requests by some of the consulting partners to add additional information to the Story Map for future projects. Since PennDOT used a consultant to develop the Story Map, its ability to revise the map was limited to the duration and funding of the consultant’s contract. PennDOT doesn’t have the resources to revise the Story Map in-house, so future revisions, which could involve different consultants, could be more difficult, according to PennDOT Project Manager Craig Sattesahn.

Regarding lessons learned, Sattesahn said it would have been useful to establish procedures and parameters up front to facilitate revisions and additional requests.

Advice for Other DOTs

According to PennDOT staff, close and meaningful consultation with local consulting parties and residents is key to local support for the product and can help obtain a great deal of important local input – such as family images, diaries, etc. – that would be impossible to get anywhere else.

It’s also important to balance high-tech and low-tech mitigation measures. Older residents are less technologically savvy than younger ones, and there are still many remote locations where high speed internet conductivity is spotty.

Since the Story Map is a technology-based product, the rapid change and evolution of technology requires attention. Although no funding is available to carry the Potters Mills Gap Story Map further, it’s likely that the next iteration of a Story Map on a different project would probably be a mobile application.

As a final consideration, PennDOT staff said a central online state repository for Story Maps from multiple projects is probably worthwhile and would not be a very expensive effort. Such a site would allow visitors to start a search at the state map level and zoom in to a number of specific project areas that have Story Maps.

The first of three construction sections of the Potters Mills Gap Transportation Project was completed in 2015. A second section began construction in August 2016, and the last section is scheduled to start construction in early 2018. More information about the PMG Transportation Project is available on the project web page.

Indirect Effects/Cumulative Impacts

Recent Developments: Montana DOT Develops Process to Assess Indirect Effects of Transportation Projects

The Montana Department of Transportation (MDT), with cooperation from the Federal Highway Administration, has released the results of research into identifying a “consistent, legally defensible, and efficient process of assessing the indirect land use and environmental effects” of MTD projects. The research includes as an appendix an Indirect Effects Desk Reference, which defines key terms, outlines regulations, and describes a screening process for determining if additional analysis is required. For more information, link to Assessing the Extent and Determinates of Induced Growth. (7-1-13)

Recent Developments: Florida DOT Issues Guidance on Cumulative Effects Evaluation

The Florida Department of Transportation has published a handbook with guidance on conducting cumulative effects evaluation (CEE) under the National Environmental Policy Act for FDOT projects that need federal funding, a federal permit, or involve a federal facility. The handbook covers when to evaluate for cumulative effects, describes FDOT’s 10-step CEE process, and addresses evaluations initiated in an area-wide planning study. FDOT also released a CEE Quick Guide summarizing its CEE process. For more information, link to the FDOT Cumulative Effects Evaluation Handbook. (2-11-13)

Case Studies: Florida - Florida DOT Develops Standard Process to Conduct Cumulative Effects Evaluations

The Florida Department of Transportation has developed comprehensive guidance on determining the potential cumulative effects of transportation projects on sensitive resources in the state.

The Cumulative Effects Evaluation Handbook is intended to provide a standard process that is efficient, legally sound, and flexible while ensuring that potential impacts on resources are fully considered and documented in the environmental review process, according to Marjorie Bixby, manager of the Environmental Management Office at FDOT.

The handbook, published in December 2012, outlines when cumulative effects evaluations are needed and provides a 10-step process to guide practitioners. The goals of the process were to provide legally sufficient evaluations; enable project time and cost savings through an efficient, standardized approach; reduce sources of disagreement over methodologies; identify potentially controversial projects early in project development; and reduce costs by using area-wide evaluations for multiple projects.

Bixby, along with FDOT Natural & Community Resources Administrator Xavier Pagan, said that development of the handbook has provided needed consistency in a process that had often been complex, confusing, and time consuming. The handbook was developed with input from state and federal transportation agencies, resource agencies, and other stakeholders such as planning organizations.

Under the National Environmental Policy Act, environmental impacts must be considered for federal actions – such as federally funded or permitted highway projects. Such impacts include direct, indirect, and cumulative effects of the action. Quoting regulatory definitions, the handbook says direct effects “are caused by the action and occur at the same time and place” and indirect effects “are caused by the action and are later in time or farther removed in distance, but are still reasonably foreseeable.”

“Cumulative impact is the impact on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions regardless of what agency (Federal or non-Federal) or person undertakes such other actions.”

While transportation agencies generally have had success analyzing direct and indirect effects for their projects, cumulative effects analyses have been more problematic – resulting in an increasing number of successful legal challenges in recent years.

The handbook describes how cumulative effects evaluation differs based on the project’s class of action under NEPA – categorical exclusion, environmental assessment, or environmental impact statement. It also provides guidance on types of projects for which a cumulative effects evaluation might be appropriate. These include: new facilities or those requiring substantial right-of-way; projects with direct or indirect impacts on environmental resources, particularly resources that are declining or that have protected status; projects that increase access to areas suitable for development; and projects where other planned actions may impact resources affected by the project.

Ten-Step Process

When further analysis is needed to address concerns about cumulative effects, a cumulative effects analysis should be conducted, focused on specific resources of concern. The handbook outlines the following 10 steps:

  1. Initiate the cumulative effects evaluation: this can be done early in the process, during scoping, to help focus studies on resources of concern.
  2. Identify resources of concern: this includes elements of the natural and human environment -- focusing on resources in poor or declining conditions that may be substantially affected by the project or other activities in the area.
  3. Define the study time frame: this involves establishing and documenting the outer years of the time horizon for identifying past and future effects.
  4. Determine the potentially affected resource area (PARA): this is the geographic study area used in the evaluation and should encompass the resources affected by the project to the extent in which its alternatives contribute to the cumulative effects on the resources
  5. Evaluate past and present impacts on the resource: this includes an analysis of past and present effects, including the current condition of each resource, how it got to its current state, and major trends affecting the health of the resource – including protective regulations or conservation programs.
  6. Evaluate effects of reasonably foreseeable future actions: this includes identifying future actions that may affect the resources of concern – including all types of actions, not just transportation projects – and describing the direct and indirect effects of these actions.
  7. Add direct and indirect effects of build alternatives: this summarizes the direct and indirect effects of the project alternatives, focusing on resources of concern for the evaluation.
  8. Assess the potential for cumulative effects: this involves using information from previous steps to consider how a particular resource responds to change and to estimate the combine effects on each resource of concern. Each project alternative is evaluated separately.
  9. Identify potential mitigation measures: all relevant reasonable mitigation measures to avoid, lessen, remedy or compensate for adverse effects must be identified and discussed, even if they are outside the jurisdiction of the agency.
  10. Document results: this involves completing the cumulative effects evaluation portion of the environmental document, using the level of detail appropriate for the class of action. The evaluation should be separate from the direct and indirect effects. The cumulative effects evaluation “should explain what the effects are, how they were analyzed, why the analysis methodology(s) are reasonable, and what the results of the analysis mean.”

According to the document, “It is important that all of the identified analytical elements be included in the cumulative effects evaluation. However, the steps may be modified to meet the needs of the project. The level of assessment and documentation depends on the nature of the project, the severity of impacts, and the potential for controversy.”

While the 10-step process is aimed at the project development phase for individual projects, the guide also allows for initiating the process in area-wide planning. Following this approach, the first six steps would begin during area-wide planning without focusing on any specific project, allowing the resource-based analysis to be used on any project proposed in the area.

Developing the Process

FDOT officials noted that the process was developed starting in 2006, following release of guidance from the National Cooperative Highway Research Program and AASHTO on indirect and cumulative effects.

Previously, each FDOT evaluation was done slightly differently, on a case-by-case basis. But Pagan said as more projects came online, the agency realized this approach was not workable. FDOT decided it needed a simpler and more consistent process. “We realized we can’t have it be case by case; we’re too big of a state, with too many projects and too many NEPA studies not to have a standard process,” he said.

A task group was assigned to develop the cumulative effects evaluation process, including representatives from 11 state and federal agencies, metropolitan planning organizations, FDOT districts and Turnpike Enterprise, legal counsel, and consultants. The process also needed to fit with FDOT’s Efficient Transportation Decision Making (ETDM) process, the state’s comprehensive approach for considering potential environmental effects during transportation planning. The process was developed over several years under former FDOT employee George Ballo and a team composed of the Central Environmental Management Office staff and consultants.

The cumulative effects evaluation process was based on research of effective practices used by state DOTs, input from stakeholders, as well as case law to help determine a sound process for such evaluations.

Lessons Learned

Pagan said having the cumulative effects evaluation process documented in a handbook is an effective way to ensure consistent application for FDOT. Since publication of the handbook, about 7 environmental impact statements have been prepared using the process, and the document has been well received by transportation practitioners and resource agencies alike, he added.

The FDOT process could be replicated by other state DOTs, he said, noting that the handbook was based in part on successful procedures developed by transportation agencies in California and Texas. Pagan and Bixby both said a key issue in developing the process was defining terms such as direct effects, indirect effects (previously known as secondary effects), and cumulative impacts. “Stakeholders needed to understand that those terms represent different things and how those things apply to transportation project delivery,” Bixby said.

Initially, FDOT had called its process the “indirect and cumulative effects process,” Pagan said. “One of the things that became obvious was that we needed to separate them.” Some stakeholders did not realize that you cannot have a cumulative impact if there are no direct or indirect impacts, he added.

Pagan also noted that agencies conducting cumulative effects analyses should use caution in identifying resources of concern. “If you’re going to identify resources of concern early, don’t make effects determinations during planning that can tie you down or cause issues when it’s not really appropriate to do so that early,” he said. “If you’re going to do it really early, be careful how you do it.”

In addition, Bixby advised being “open and communicative with the relevant agencies and stakeholders – and keep the agency with jurisdiction over the resource informed.” Because these groups helped FDOT develop its process, the handbook encourages things like looking at long-range plans, talking to metropolitan planning organizations, and talking to counties about their development plans.“It’s important to get the right players involved,” Pagan added.

“Ultimately we see that it’s very important to have a standardized process that in itself is flexible enough to apply to all sorts of situations, depending on the nature of the project and the nature of the resources in the project area,” Bixby said. The 10-step process can be applied to a variety of situations and adjusted as needed. At the same time, it documents that FDOT has carefully conducted a thorough cumulative effects determination, she added.

Case Studies: Montana

Case Studies: Montana - Montana DOT Develops Guidance for Indirect Effects Analyses

A guidance document developed for the Montana Department of Transportation (MDT) will provide needed consistency and efficient procedures for determining the indirect land use and environmental effects of transportation projects in the state.

Issued in the summer of 2013, MDT's Indirect Effects Desk Reference provides an overview of regulatory requirements related to indirect effects, a step-by-step screening process to determine what level of analysis is warranted and a framework for conducting detailed analyses, where needed.

MDT developed the guidance to help agency staff and consultants determine the potential for induced growth effects from road projects, taking into account the state's unique rural setting, according to Heidy Bruner, Environmental Services Engineering Section Supervisor at MDT. MDT plans to incorporate the guidance into its Environmental Manual this summer for use on upcoming projects, Bruner said.

The guidance will help ensure compliance with requirements for analyzing projects' potential indirect effects under the National Environmental Policy Act and Montana Environmental Policy Act.

Screening Process Developed

The screening process considers information that is readily available early in the project development process regarding the characteristics and location of the project.

A five-part screening process provides a list of questions for staff to consider. These include:

  • whether the project is exempt, such as highway maintenance and rehabilitation on the same alignment with no increase in capacity;
  • whether the project has an economic development purpose included as part of the purpose and need;
  • whether the project will substantially improve accessibility based on indicators such as travel time to key destinations;
  • whether developable land is available in the areas served by the project;
  • and whether the project region is experiencing population and/or employment growth.

Using this initial screening process, the vast majority of MDT's projects will not require detailed analysis.

Detailed Analyses

The Desk Reference provides a framework with the following steps for conducting a detailed analysis, where needed:

  • determine study goals and methodology;
  • define study area boundaries and time horizon;
  • assess existing and future no build land use patterns;
  • assess future build condition land use conditions and indirect land use effects;
  • assess the potential for indirect impacts on sensitive resources;
  • develop potential mitigation measures; and
  • document the process and results.

For the actual indirect effects analysis, the guidance recommends a combination of "collaborative judgment," which determines the "no build" vs. "build" incremental change in land use, and "allocation models," which determine the allocation of growth predicted through collaborative judgment to specific sub areas. "Collaborative judgment incorporates input from other people knowledgeable of the study area (local experts) to inform conclusions about future land use conditions, whether through informal interviews or more formally through a Delphi panel. Allocation models can allow the analyst to distribute a defined amount of indirect land use change at a disaggregate level (such as allocating growth in county to individual municipalities or allocating growth in a city to census tracts or traffic analysis zones," the summary said.

Research Informed Development of Guidance

The guidance document was based on the results of research on MDT's existing practice, including a review of environmental documents developed for projects, interviews of MDT staff, and a survey of resource agency staff. The research also included a review of relevant case law to determine how courts have interpreted when indirect effects analyses are adequate.

Researchers determined that indirect land use effects assessments in Montana had been conducted in an "ad hoc" manner. While some environmental documents provided well-thought out explanations of the relationship between the project and potential future land development, none of the documents followed a clearly defined assessment process.

Process Offers Needed Consistency

Bruner said the research showed that there was not a large deficiency in the agency's process for conducting indirect effects analyses. Nevertheless, the new procedures offer needed consistency and structure that has been well received.

MDT has conducted training to ensure that staff and consultants have an efficient process for meeting requirements for indirect effects analyses under NEPA and MEPA. The process will be updated going forward, as needed, and will be coordinated with future updates to the MDT Environmental Manual. Bruner said the process is flexible and could be transferable to other state DOTs, but it would need to be tailored to the unique communities of each state.

According to Leo Tidd, a member of MDT's consultant team with The Louis Berger Group, the Desk Reference incorporates concepts and best practices that could be adopted by other states. "The basics of right-sizing the level of analysis to the project issues, documenting the rationale for decisions, avoiding inconsistencies within the environmental document (such as stating the purpose includes economic development, but then failing to analyze the environmental impact of that development) apply everywhere," Tidd said.

The process used to review the state of the practice at MDT could be applied by other states to assess how they are doing on this issue, he added. In addition, the screening process could easily be adapted for use in other states to improve NEPA document timeliness and defensibility, he said. "The questions themselves are not specific to Montana and deal with drivers of land use change that are universal," Tidd said.

Case Studies: Texas - Texas DOT Offers Simplified Guidance to Assess Projects' Indirect and Cumulative Effects

Challenges associated with assessing the indirect and cumulative effects of transportation projects across Texas have been eased by a revised and simplified set of handbooks and guidance documents developed by the Texas Department of Transportation (TxDOT).

TxDOT faces a distinctive challenge when assessing the indirect and cumulative effects of its projects across the state: the state lacks a statewide land use management policy and manages its lands at the local level. The lack of a statewide approach to land use creates varying conditions across the state that make a strictly defined indirect and cumulative effects process unfeasible—the same project could have drastically different indirect and/or cumulative effects under contrasting land use conditions created by the various land use policies of different cities.

For example, where one city may employ strict zoning laws, other cities may frequently and broadly grant variances; an interchange project that may reasonably be assumed to have a ½-mile radius Area of Influence (AOI) in the first city may require an AOI with a radius of several miles in the second city because the second city’s less strict zoning creates the possibility of a geographically much larger AOI.

The varying land use climates across the state and extensive use of frontage roads parallel to limited access facilities create an interesting challenge for Texas: how to create guidance that balances streamlining the indirect and cumulative effect analyses with the unique conditions presented by different local approaches to land use regulations.

Developing the Guidance

The Council on Environmental Quality (CEQ)’s guidelines for National Environmental Policy Act (NEPA) implementation (40 CFR §§1500-1508) established the requirement for federal agencies to consider direct, indirect, and cumulative impacts in the NEPA process. Subsequent guidance and resources provide further direction on considering indirect and cumulative effects under NEPA (e.g., AASHTO Handbook 12, NCHRP Report 466, FHWA Interim Guidance and Q & A, and NCHRP Project 25-25, Task 43).

TxDOT developed its own cumulative impacts guidance in the early 2000s, which was met with positive feedback from around the state and other DOTs. Soon after, the agency began developing a guidance that incorporated both indirect and cumulative impacts. Following the suggestion of FHWA Texas Division, the more comprehensive guidance document pulled from a variety of sources like the NCHRP Report 466—the Transportation Research Board’s Desk Reference for Estimating the Indirect Effects of Proposed Transportation Projects—to provide TxDOT project teams with a step-by-step process. Initially implemented in 2009, minor updates to the guidance document in 2010 added keys for success and how to approach small projects through added-capacity Categorical Exclusions.

Implementing the 132-page guidance document proved both successful and challenging. The guide acts as a detailed “how-to” resource of indirect and cumulative impact analysis methods. TxDOT learned, however, that document users found its size cumbersome and struggled with the unfamiliar technical terms (e.g., notable feature, impact-causing). In response, TxDOT split the guidance into two separate guidance documents—one for indirect effects and one for cumulative effects—and simplified them by consolidating the number of steps, removing technical jargon, and splitting out easily convoluted concepts, such as growth-related effects and encroachment effects. TxDOT also added an Indirect and Cumulative Impacts Handbook to provide a high level overview of the steps to conduct a thorough and defensible analyses of indirect and/or cumulative impacts that may occur as a result of a transportation project.

Nicolle Kord, TxDOT’s indirect and cumulative impacts expert, said the agency has “attempted to structure our guidance to be more accessible to a wider audience; in particular for those new to indirect and cumulative impact analysis.” For example, she said, TxDOT “attempted to make these complex ideas easier to understand by breaking them up into their individual parts (indirect encroachment impacts, indirect induced growth impacts, and cumulative impacts) as well as by removing jargon and putting guidance in plain language.”

Key Features of the Guidance Documents

The following table illustrates several key features of TxDOT’s indirect and cumulative effects guidance documents that contribute to their efficacy.

Lessons Learned

From its original cumulative effects guidance through its most recent guidance updates, TxDOT emphasized the following lessons that may be transferable to other state DOTs:

  • Know your state: A blanket approach to indirect and cumulative impacts analysis does not work in Texas. Though other state DOTs may have a more uniform statewide land use climate, it is critical to know your area and understand that indirect and cumulative impacts are complex and often call for a case-by-case approach. Texas uses decision trees (Induced Growth Indirect Impacts Decision Tree and Cumulative Impacts Decision Tree) to help determine which projects need indirect and cumulative impact analyses.
  • Simplify: TxDOT’s simplified approach to indirect and cumulative impact analyses made it more approachable for district environmental staff, who are project and technical experts but not necessarily versed in all aspects of NEPA.
  • Consider process improvements: By emphasizing technical reports and coordination early in the NEPA process, TxDOT was able to shorten their review cycles, save time and money, and produce stronger analysis in its documents.
  • Provide one-on-one coaching: In addition to regular conference calls (“NEPA Chats”) with districts to identify and provide guidance on various NEPA issues, TxDOT found great value in one-on-one coaching with district subject matter experts on individual projects rather than implementing agency-wide theoretical classroom training in how to apply the guidance.

Case Studies: Colorado - Colorado Landscape Architecture Manual Provides Guidance, Best Practices

At the Colorado Department of Transportation, effective landscape architecture provides benefits beyond just a pretty view.

In fact, CDOT regards one of the major focuses of landscape architecture to be the “protection and enhancement of natural systems affected by the transportation system.”

To ensure this, the transportation agency recently issued the CDOT Landscape Architecture Manual (2014). The manual, which took about two years to write, brings together all information relevant to highway landscape design including aesthetic, sustainability, environmental, and landscape considerations.

The intent of the manual is to ensure that federal and state requirements are addressed uniformly across the agency’s decentralized regions and the state’s diverse geography. “Transportation design is required to fit [in with] the existing physical environment using context sensitive design and practices,” according to Mike Banovich, a landscape architect who has been with CDOT for 25 years.

Banovich said CDOT undertook creating the manual because it recognized the need to create guidance that would “improve program quality and compliance.”

Focus on Context

The manual presents landscape architecture as a component of the entire planning and design process for transportation projects, using a multi-disciplinary approach. There is a “direct relationship” between design and place, the manual says.

With that in mind, the manual provides broad-ranging guidance on how to plan and design landscapes that appear natural, conserve water, protect resources, and are sustainable for the life of the road or highway.

The intent is to “expand transportation design decisions beyond strictly functional and engineering criteria within a Context Sensitive Solutions approach,” according to the manual.

Protecting vegetation, designing areas for new plantings, and controlling noxious weeds are key components of the landscape architect’s job and the manual discusses best practices and requirements under state and federal laws. Each of these tasks involves many variables, not the least of which are climate and geography.

Use of ‘Design Zones’

The identification of design zones is “critical to creating a relationship between transportation and landscape,” the manual said.

According to the manual, the state of Colorado encompasses five design zones:

  • High Plains (east of Denver),
  • Front Range Urban (Denver and its suburbs),
  • Southern Rocky Mountain,
  • Western Slope Basin, and
  • Great San Luis Valley (at the border with New Mexico).

“By understanding the characteristics of each zone, CDOT can design unified corridors with consistency and a recognizable sense of place in each zone,” the manual said. For example, “the road alignment should respond to the dominant land form of a zone while the plant palette should be derived from plant species native to the zone and micro-climatic conditions. Details, such as colors and textures, applied to transportation facilities could be reflective of the cultural and landscape context.”

The design zones are consistent with the ecoregions described in the Federal Highway Administration’s Vegetation Management: An Ecoregional Approach handbook, issued in 2014. The handbook defines ecoregions as areas of similar geographic, vegetative, hydrologic, and climatic characteristics, and emphasizes the use of native plants along roadsides to reduce maintenance costs, provide better erosion control, and create ecological diversity.

Native Plants a Requirement

At CDOT, a nearly four-decade-old policy requires department personnel and contractors to use native or dryland adaptable plants on all landscaping projects. To implement that policy, the manual directs landscape architects to preserve or salvage existing vegetation in the project area. If that is not practical, the area must be replanted with native species and must follow the principles of xeriscaping, a technique that reduces or eliminates the need for irrigation.

“Xeriscaping is very important [at CDOT] because Colorado is primarily a semi-arid cold desert experiencing drought and extreme weather fluctuations,” Banovich said. “CDOT’s objective is to use native plants adapted to our arid climate in non-irrigated conditions.”

Additionally, the manual directs that existing topsoil must be preserved and reused, which includes stockpiling during the construction phases of projects. Topsoil can be imported from elsewhere only as a last resort.

Threats from Invasive Species

Like many states, Colorado faces threats from invasive plant species that diminish the value of cropland, rangelands, and native habitat. The state has enacted legislation that identifies noxious weeds that are to be contained, controlled, or eliminated. Also, state law for the protection of stream-related fish and wildlife requires the department to consider noxious weed eradication while planning for construction projects in riparian zones, according to the manual. Additionally, construction equipment and stockpiled topsoil must be kept free of invasive weeds.

Vegetation planted or maintained in highway rights-of-way must not create unsafe conditions for drivers and vehicles. The manual discusses the importance of maintaining sight distances for drivers, having trees and other large plantings set back from the roadway, and avoiding conditions where too much shade can cause visual hazards or allow ice to form on road surfaces. Additionally, newly constructed features in rights-of-way should include landscape designs that minimize rainwater runoff and the need to irrigate.

Role of the DOT Landscape Architect

In addition to laying out the standards and best practices, the manual provides information on the role of the landscape architect in the transportation department. The landscape architect is a valuable participant in projects from the early planning stages through the National Environmental Policy Act (NEPA) process and even after completion, according to the manual. Many state departments of transportation such as CDOT have landscape architects on staff.

The landscape architect’s role is “to act as the design liaison between environmental specialists and engineers…by incorporating environmental needs and requirements into the project objectives,” Banovich said. Additionally, stormwater management and water quality have “become important components” of the landscape architect’s job in recent years, Banovich said.

According to the manual, planting design concepts are a result of the landscape architect’s training in elements such as color, form, line and texture. The placements of plantings on the highway right of way serve to:

  • Protect against erosion.
  • Minimize water use through the use of native drought tolerant species, mulches, and the use of irrigation systems designed for low precipitation systems.
  • Promote stormwater reduction runoff practices via interception and root infiltration.
  • Screen undesirable views from the highway and screen highway from adjacent land owners.
  • Guide traffic.
  • Avoid root or foliage contact from deicers.
  • Minimize maintenance requirements.
  • Provide shade at scenic overlooks or at rest areas.
  • Frame and emphasize a view.
  • Screen highlight glare.
  • Mitigate impacts to surrounding communities.
  • Reduce driver monotony.
  • Provide wildlife habitat.
  • Salvage, protect or reuse existing vegetation, when possible.
  • Mitigate for wetland/riparian impacts.

Lessons Learned

For other DOTs considering creating their own landscape architecture manual, Banovich suggests obtaining “concurrence from DOT leadership” while also involving environmental resource specialists.

Additionally, it is important to “define the use of the manual in a policy objective which in turn will justify the use of the manual” as a part of the DOT’s operational procedures, Banovich said.

Case Studies: Virginia - VDOT Program Aids Pollinators While Supporting Transportation Goals

The Virginia Department of Transportation (VDOT) is implementing a Pollinator Habitat Program along the state’s highway system that provides much-needed waystations for monarch butterflies and other dwindling pollinator species. Moreover, according to agency officials, the program is entirely consistent with the department’s transportation priorities.

“Our savings on mowing costs alone will be significant,” said Diane Beyer, State Vegetation Management Planner for VDOT’s Maintenance Division. “Currently, each roadside mowing cycle costs approximately $12 million. Under the program, our goal is to reduce mowing frequency from three times a year to once a year.”

Under the program, Beyer explained, stretches along the state’s highways and at rest areas are being planted with native vegetation that provides food and habitat for pollinators. The multi-colored vegetation includes species such as milkweed for monarch butterflies, asters for bees, and goldenrod for birds, bees, and butterflies.

Beyer said the program will bring multiple transportation and environmental benefits. First, the program supports VDOT’s vision of safety while providing increased habitat areas. For example, attractive roadsides have been shown to reduce driver fatigue and improve mood; and wildflower perennials and grasses are not favored by deer, a potential driver hazard. In addition, mowing only the shoulder (and allowing wildflowers to continue to bloom) still maintains line of sight and space for motorists to pull off, and it prevents encroachment of shrubs and trees.

In addition, roadside maintenance time and costs are reduced through planting of self-sustaining, native vegetation. The vegetation stabilizes slopes and reduces erosion; increases storm water and nutrients retention due to deep roots; and reduces other vegetation maintenance costs such as invasive species control and herbicide applications. It also provides a smooth transition to adjacent properties.

The program also contributes to the agency’s broader Integrated Vegetation/Pest Management system through reduced use of herbicides; increased erosion, sediment and stormwater runoff control; and reduction in the presence of invasive species. An additional benefit is the increase in visual aesthetics.

Besides supporting VDOT’s transportation goals, Beyer said, VDOT’s Pollinator Habitat Program also supports the Department’s MS4 program, a critical element of Virginia's stormwater management program. On a national level, it supports FHWA’s Every Day Counts initiative though what Beyer calls its “low-tech, back to basics” approach to innovation and its focus on safety. In addition, the program aligns well with the Presidential Memorandum issued in 2014 on creating a federal strategy to promote the health of honey bees and other pollinators.

Genesis and Development

“As it happened, the inception of our program preceded the Presidential Memorandum by several months,” said Beyer. “The timing was very helpful to us in terms building internal support for what was viewed as a very new approach to maintenance.”

The pilot program began in the fall of 2014. Four plots were planted with plant plugs in northern Virginia, each 900 square feet and containing 13 different species. These initial plantings provided Beyer and her team with a useful means of learning what works and what doesn’t. The plantings also provided a foundation for beginning to educate agency staff and the public about the program and the reasons behind it.

In September 2015, a 15,000 square foot meadow area was planted at a rest area on Interstate 95 (a migratory flyway), also in northern Virginia. Three smaller plantings simultaneously were installed near the rest area building. The latter plantings serve as educational stations with interpretive signage for visitors. A total of 8,000 nectar and pollinator plants from 23 species were planted.

Also during the fall, three areas in southwestern Virginia were planted with seeds (not plants); one of the goals was to analyze which seed mixtures and types of seed planting methods work best. In this case, the areas were medians and roadsides. And at the end of 2015, the program moved into the western part of the state for the first time.

Plans call for the program to be implemented statewide. In 2016, while results from the seed-planting location are gathered, the focus will be to continue to create naturalized gardens and meadows with mature plants at state rest areas. In the meantime, interpretive signage continues to be developed and installed at existing areas. Beyer said the team will integrate solutions to challenges they faced in the early months, such as ensuring continued maintenance of the plots until the vegetation is well established.

Funding and Partners

Currently, the program primarily is funded through the purchase of the “wildflower” license plate, which will continue to be offered to drivers and is supported by the Virginia Garden Clubs. Beyer said, the newly minted “pollinator” license plate currently does not financially support the program, but a bill is being introduced in the 2016 Legislative session to remedy that and direct funds to VDOT in support of the Pollinator Habitat program.

Partners have been essential to the program’s growth, she continued. They include Virginia Dominion Power/Dominion Trust; Valley Land; White House Office of Science & Technology; Loudoun Wildlife Conservancy; Virginia Native Plant Society; and PBS Films. These groups continue to provide needed funding, labor and materials.

Advice for Other DOTs

Beyer said other state DOTs either are planning or beginning to carry out similar programs. Examples included a corridor restoration project from Texas to Minnesota, as well as programs in Illinois, North Carolina, Ohio, and Vermont. Part of the challenge for interstate initiatives, she pointed out, is that DOTs have varying organizational structures, which can make obtaining a multiple-state green light, as well as ongoing cross-state coordination, challenging.

Her advice to other state DOTs contemplating a similar initiative centered on two themes: education and partnering. Educating the public is important, Beyer said, but perhaps even more critical is internal agency education, especially for two groups: upper management and the maintenance team tasked with actually carrying out the work. As partnering goes, securing early collaboration from groups such as native plants societies, Extension Services, garden clubs and wildlife organizations is key to success. They will all help with the outreach and education of the program as well.

Finally, she urged agencies not to overlook the corporate sector: it definitely needs to be included on agencies’ teams to bring key expertise, networks, and financial support to the table. Partnerships also give others a sense of stewardship in promoting and furthering the program.

“Our organizational structure is such that safety rest areas are managed centrally, making it easier to create a consistent program face. Consistency is important in that it brands the program and makes it more comprehensible and recognizable to the public and staff. Rest areas are also an excellent way for us to educate the public about the new program and the new mowing practices and gardens,” she said.

“Education, both internally and externally is a paramount necessity in a program such as this. You want to make sure everyone comprehends the 'whys' so that support comes forth from a place of knowledge and understanding," said Beyer.

She suggested that education and outreach be an integral part of a similar program, as new techniques and ideas are not always well received when staff and the public are not included in the “whys” and allowed to ask questions.

Case Studies: Washington State

Case Studies: Washington State - Reduced Roadside Mowing Policy Promises Multiple Benefits in Washington State

Reduced fuel consumption, fewer carbon emissions, better weed control, cost savings and improved habitat for pollinators are among the many benefits of the Washington State Department of Transportation’s (WSDOT) new policy to reduce mowing on the state’s roadsides.

WSDOT’s revised mowing policy, adopted in 2015, changes the focus of roadside maintenance from aesthetics in favor of a more natural approach.

Under the revised mowing policy, WSDOT has eliminated almost all mowing that had been conducted for aesthetic reasons in areas with wide rights of way extending beyond 30 feet from the pavement edge. The change will result in a one-third reduction in mowing for non-safety-related reasons annually, according to an agency summary.

The policy specifies that routine mowing “will generally be limited to one pass adjacent to the paved shoulder except in rare cases where a wider annual mowing swath is necessary for safety or for specifically indicated vegetation control.”

Most areas beyond the 30-foot limit that had previously been managed with routine mowing will now be designated as “naturally managed areas” and left to grow mostly naturally, unless hazard trees or designated noxious weeds need to be controlled. Certain higher profile areas will be selectively managed as meadows where all weeds are controlled and natural succession of desirable native plants is encouraged.

In a related effort, the agency is conducting a pilot study during the summer of 2015 that will be the first published research in the country to provide a cost/benefit analysis of grazing (using goats) as a mowing tool in state highway rights of way.

All of these actions are part of a multi-year strategy by the agency to create more self-sustaining and lower-maintenance roadsides that are complimentary to the surrounding native ecosystems, according to Ray Willard, Roadside Maintenance Program Manager at WSDOT.

Benefits of Reduced Mowing

Benefits of reduced mowing include lower fuel consumption—the department expects to save approximately 2,500 gallons per year of diesel fuel for mowing equipment—and an associated reduction of 23 metric tons in CO2 emissions.

WSDOT also expects to save money in labor and equipment costs. The department will be able to divert its maintenance crews to higher priority work and also switch from using large tractors with wide mowing decks to smaller, more efficient and versatile mowers. Overall, WSDOT expects to save approximately $550,000 each year in mowing costs.

The revised policy will also provide more effective nuisance weed control in designated high profile areas. In freeway interchanges and designated scenic corridors, WSDOT will carefully coordinate mowing patterns and timing with other vegetation management treatments with the goal of removing unwanted nuisance weeds and trees and encouraging more desirable native roadside plant communities over a series of years.

Looking out for Pollinators

Another benefit of reduced mowing is improved habitat for pollinators such as honey bees and butterflies, a topic that has recently taken on national significance. In June 2014, President Barack Obama issued a memorandum directing federal agencies to take actions to protect pollinator species, including calling on the Department of Transportation to work with state DOTs to increase pollinator habitat along roadways.

Roadsides can offer pollinators improved forage for food, breeding, or nesting, and help link fragmented habitat, according to a literature review released by the Federal Highway Administration in May 2015. The report supports the development of best management practices for pollinator habitat protection and enhancement in highway rights of way.

The Transportation Research Board is also planning a webinar on promoting the practice of integrated vegetation management and managed succession over routine mowing, according to Willard, who also serves as research coordinator for TRB’s Roadside Maintenance Operations Committee (AHD50).

Federal leadership together with the agency’s executive leadership on the pollinator issue were contributing factors leading to WSDOT’s revised mowing policy, according to Willard. “What we have now is really good motivation from the top down that we should be taking a more natural approach to managing roadsides,” Willard said.

He also pointed to a recent FHWA publication, Vegetation Management: An Ecoregional Approach, which he said laid the groundwork nationwide for this new approach. The FHWA document, described in this agency article, has been distributed but not yet posted online by the agency.

System Tracks Acres Mowed

To monitor progress in implementing the new policy, WSDOT maintenance staff will be deploying the department’s new Highway Activity Tracking System (HATS). The system allows field staff to document their vegetation management activities in greater detail using tablet computers and geographic information system mapping.

In the past, documenting the number of acres mowed was “kind of a wild guess,” according to James Morin, Maintenance Operations Manager at WSDOT. “You knew how wide the mower was and roughly how far you travelled.” But under the new system “as long as [maintenance crews] turn on their iPADs, they’ll know exactly how many acres they mowed.”

HATS will be integral to implementing the revised mowing policy because it will allow the department to document savings in terms of fuel consumption, carbon emissions and other lifecycle costs, according to Willard.

Public and Agency Outreach

As roadsides begin to take on a more natural and less manicured appearance, people will continue to question and debate the merits of visual quality vs. environmental sustainability, Willard said. “It is important that we collect and maintain clear scientific evidence of the overall environmental benefits from mowing less,” he added

The popular desire to see neatly mowed roadsides carries over into the culture and historic practice of highway maintenance, where agencies receive positive feedback when the roadsides are mowed, Willard said.

There’s also the potential for political pressure on state DOTs to mow for aesthetics in the name of tourism, quality of life, or for the benefit of neighboring businesses, according to Willard.

To help educate the public, WSDOT is developing a four-page color print folio on the revised mowing policy and is developing similar language to feature on its website.

To help convince the agency’s staff, managers have focused on the benefits to the natural environment. “The maintenance employees take a lot of pride in a neatly cared-for roadside, so it’s really [about] shifting from seeing the roadside as a pretty thing to seeing it as a beneficial thing to the natural environment,” Willard said.

Where environmental considerations alone might not convince staff, the economic savings are also compelling, according to Morin. “If we can have a native roadside that’s high functioning, we don’t typically have as many weed issues and it doesn’t cost us as much in terms of effort or money to maintain,” Morin said.

An important factor in WSDOT’s success in implementing the new policy has been having planning guidelines and objectives that are consistent statewide, yet still offer flexibility to the local maintenance areas, according to Willard. For WSDOT this has involved updating the integrated roadside vegetation management plans for each of the state’s 24 maintenance areas to incorporate reduced mowing on a case by case basis.

Another key strategy within the new policy is encouraging local governments to “adopt” freeway roadsides through their cities if they desire a more park-like appearance. WSDOT has developed permits to allow this type of local participation where appropriate.

Testing Goats as ‘Biological Mowers’

In a related effort to evaluate a more natural approach to vegetation management, WSDOT is conducting a pilot project using grazing goats as a mowing tool on state highway rights of way.

“Goats are basically biological mowers,” Willard said, and can perform a similar function as mechanical mowing but without burning fossil fuels and generating carbon emissions. Another advantage is that some weed seeds are sterilized as they pass through a goat’s digestive system, allowing for more effective weed control than mechanical mowing. Goats can also easily access steep and uneven terrain.

However, concerns over the use of grazing in highway applications include higher costs associated with fencing, watering and supervising the animals; liability; and potential distractions to drivers, according to an agency summary of the research.

While there has been extensive research on grazing for vegetation management and weed control over the years, the feasibility and cost/benefit of grazing in the highway right of way has not been well documented. To help do this, WSDOT is conducting field trials using goats in three different vegetation management situations and terrains around the state.

The study is testing goats for routine mowing of unwanted weeds and brush around fenced stormwater ponds at several sites near Vancouver, using goats donated by a WSDOT maintenance employee. The trials also will study water quality impacts in areas with standing water and potential outflow.

A second site in Spokane is studying the use of goats to prevent or delay seed production in a noxious weed infestation along US 395.

Finally, the department is using goats to clear unwanted vegetation from a former homeless camp along Interstate 5 in Olympia.

As part of the study, WSDOT will document all costs associated with labor, feed, transportation, and fencing of the goats and will issue its findings in a research report, expected in fall of 2015.

The initial finding of the research is that in general, goats have a very limited application for roadsides, according to Willard. One type of situation that may prove effective is in controlling vegetation within fenced stormwater ponds, where the animals don’t require constant supervision and don’t present a potential distraction to drivers.

NEPA Process

Recent Developments: GAO Report Finds Some Improvement, Data Gaps in NEPA Assignment

A report assessing the use of project streamlining provisions under the National Environmental Policy Act and whether they have accelerated project delivery has been issued by the Government Accountability Office. The report found that, of provisions that mainly created new categorical exclusions, 10 out of 17 of these provisions were used by 30 or more state DOTs and generally sped up projects. The report also found that, of the six states assigned NEPA authority for highway projects, California reported that it has reduced environmental impact statement review time from 16 years to 6 years. However, both California and Texas have faced challenges in establishing baselines, such as how many and which projects to include, and the other four states had not reported results. Additionally, the report found a need for developing evaluation methodologies, including baseline time frames and timeliness measures. For more information, link to the report. (1-30-18)

Case Studies: Ohio - Ohio DOT Launches Expanded Online Environmental Documentation System

The Ohio Department of Transportation (ODOT) has launched an expanded and renamed version of its online environmental documentation system and is steadily adding time-saving bells and whistles. The system, formerly known as CE Online, has been rebranded ENVIRONET to reflect the comprehensive capabilities of the system and to allow for future planned enhancements.

ENVIRONET facilitates the electronic processing of National Environmental Policy Act (NEPA) documents. Categorical exclusions (CEs) can be fully completed online because the forms are built into the system. The associated electronic project file houses supporting documentation. While Environmental Assessments (EAs) and Environmental Impact Statement (EISs) still need to be completed outside the system, both the environmental document and its associated documentation are uploaded to the electronic project file set up for the project.

The electronic project file is a very important part of the system since it allows real-time access to draft and final supporting documents. Subject matter reviewers can check out draft technical reports, make comments, and check them back in. Once the technical report is approved, it can be finalized in the system. This capability allows for version control and the system also tracks when documents were uploaded, when they were modified, and by whom.

The system also provides a standardized process for uploading reports, technical studies, agency coordination, and decision-making documents. It allows the user to select appropriate drop-down options to consistently name documentation. The process is capped off with an electronic review and approval function, meaning no printing, signing, scanning and uploading is required. Users have access to particular sections of the system based on their respective roles.

“Rebranding is a reminder that our system offers more than just streamlining CE preparations,” said ODOT Assistant Environmental Administrator Erica Schneider. “One of EnviroNet’s greatest benefits is that it provides all sorts of real-time information to our project team. There’s no longer a need for mailing or e-mailing information back and forth.”

ODOT has continued to save approximately $100,000 per year since its CE Online went live in 2012, Schneider said. Even better, savings could double as additional enhancements are added.

NEPA Assignment a Motivator

In December 2015, ODOT assumed federal authority for NEPA reviews from the Federal Highway Administration, giving the state agency added responsibilities for ensuring environmental compliance. These new responsibilities provided additional motivation to add new capabilities to the system, explained Kevin Davis, Environmental Supervisor with ODOT. For example, the system now includes a Project Details Tab that allows ODOT users to enter dates for specific environmental milestones related to the project, whether it’s a CE (the vast majority), EA, or an EIS.

“We now are required to closely track time savings,” he explained. “Using the project file, we can access completion dates for each stage of a project from start to finish. With these details in hand, we can identify exactly where we are saving time or, in some cases, exactly where we need to find ways to work more efficiently.”

Another recent addition is the FHWA Auditing Tool. During annual audits under the NEPA assignment program, auditors can log in at the home page, select the date range they are seeking, and view all of the documents approved during that time period.

Lessons Learned, Advice to Other DOTs

In planning and developing enhancements to ENVIRONET, ODOT has gathered suggestions from inside the agency and also used information from similar online systems in Pennsylvania, Virginia, and Texas. Virginia DOT, for example, has integrated a GIS component into its system, an enhancement ODOT now is considering.

Schneider said developing an effective system that can be built to grow and adapt requires funding, patience, and time. The original system cost about $600,000 to develop and it took just over a year.

She offered the following advice to other DOTs contemplating building similar systems:

  • Gain and maintain strong support from upper management.
  • Develop a front-end detailed communications plan. Processes, roles, and protocols should be clearly spelled out to avoid duplication and misunderstandings.
  • Plan on dedicating a lot of time to working with programmers and subject matter experts as the system is developed.
  • Involve everyday users of the system at the beginning of development. Learn about their needs and solicit their ideas. Before deployment, carry out user acceptance testing and make changes where needed.
  • Provide comprehensive training to all users. Go beyond “train-the-trainer.” Conduct classroom training. Develop a website that provides guidance on tasks such as how to check out a document for review.

Looking Ahead

As of October 2016, more than 6,600 projects were housed in ENVIRONET including approved documents, those in process, and those submitted for review and/or approval. More than 600 people had been granted access to the system, including ODOT staff, regulatory agencies, and consultants. The eventual goal, Schneider said, is for all involved resource agencies to carry out their reviews using ENVIRONET and to make all approved environmental documents available to the public online.

Another planned enhancement will facilitate the completion and coordination of Ecological Survey Reports. Under the current system, regulatory agencies such as the U.S. Fish and Wildlife Service receive as many as 60-70 such reports a month. They are uploaded to an internal local drive and sent out in batches via an extranet site at the end of the month. The new feature, which would incorporate the report into the CE form, is scheduled for incorporation in 2017.

Case Studies: California - Caltrans Uses Air Bubble Curtain Technology to Protect Wildlife During Bridge Implosions

The California Department of Transportation (Caltrans) is using cutting-edge technology to remove the marine foundations of the former East Span of the San Francisco-Oakland Bay Bridge while protecting area wildlife and reducing project cost and schedule.

The technology controls the blast sequence down to microseconds by using a computer system to precisely detonate hundreds of small individual charges to implode the foundations, thus greatly reducing impacts. At the same time, Caltrans is implementing a blast attenuation system that creates a shield of air bubbles to abate resulting sound waves and pressure.

“By employing leading edge technology, we have reduced the temporal environmental impact of our demolition work from years to seconds,” said Stefan Galvez-Abadia, Chief, Office of Environmental Analysis and San Francisco-Oakland Bay Bridge Environmental Manager. “Simultaneously, we are working more safely and efficiently and saving money.”

The agency’s other option would have been to build a cofferdam, he said, which is an enclosure around each foundation pumped dry to enable loud, heavy machinery to carry out the demolition work. With a limited construction window each year, it could have taken up to four construction years to remove each foundation, a very expensive undertaking. In addition, this approach can result in continuous environmental impacts and safety risks.

“Real-time results have exceeded those anticipated by the model,” Galvez-Abadia said. “Both in-water noise and pressure as well as water quality impacts were significantly less than anticipated. We view this cutting-edge technology as another valuable tool in our toolbox.”

Caltrans’ implosion technology supplements additional steps it routinely takes to protect wildlife. The marine foundations are located in a portion of the San Francisco Bay that contains several fish species protected by the Endangered Species Act as well as marine mammals protected by the Marine Mammal Protection Act. Caltrans avoids impacts to most of these species through seasonal work windows. However some species are present in the Bay year round and the agency has developed specific work windows to avoid impacts to these species to the greatest extent practicable.

History of Project

The reason for removal dates back to 1989, when a segment of the bridge partially collapsed during the Loma Prieta earthquake. Although it reopened later that year after extensive retrofitting, experts decided that the East Span needed to be more earthquake-resistant than would be possible by retrofitting the existing bridge. Construction of a replacement span began in 2002 and was opened to traffic in 2013. After beginning to dismantle the original span’s superstructure in 2013, Caltrans began to remove its foundations as stipulated in the final Environmental Impact Statement (EIS) for the replacement span.

The first of the former East Span’s 21 foundations, called Pier E3, was imploded in November 2015. Two more foundations followed suit in 2016, and an additional six to thirteen are slated for demolition in 2017 and 2018, when the project is slated for completion.

Permits, Protections

Caltrans’ engineers and environmental team spent years working closely with a variety of resource agencies to determine how best to minimize potential environmental impacts to area wildlife and habitat.

Before beginning the project, the agency received federal permits from the National Marine Fisheries Service (NMFS), the U.S. Army Corps of Engineers, the U.S. Coast Guard, and the U.S. Fish and Wildlife Service (USFWS). State agencies granting permits included the California Regional Water Quality Control Board, the California Department of Fish and Wildlife, and the San Francisco Bay Conservation and Development Commission. These permits covered the building of the new bridge as well as the removal of the original bridge by mechanical means.

As the implosion work advances, Caltrans will continue to implement its impact avoidance and minimization measures. In addition, marine mammal species in the area will be protected via monitoring of pre-established exclusion zones around each foundation. If marine mammal species such as harbor seal, sea lion, or harbor porpoise, are spotted, the implosion will be delayed until the individual has moved outside the zone. Water quality and air quality monitoring also will continue to be conducted.

Perhaps the most powerful piece of the protection arsenal is Caltran’s air bubble curtain. To activate the system, a compressor pumps air through a manifold of perforated pipes set in a steel frame. Multiple frames contiguously surround the foundation and are activated just before the implosion process begins. The escaping air bubbles create a continuous shield, or wall, that provides a robust acoustic barrier.

Lessons Learned and Advice

Caltrans has tweaked several of its procedures along the way, said Galvez-Abadia. For example, after analyzing the results of the Pier E3 Demonstration Project, then determining that potential impact areas were less than modeled and subsequently consulting with associated resource agencies, the expanse of the wildlife exclusion zone was reduced to reflect the minimized impacts.

He recommends that other state departments of transportation consider adopting a similar approach for their own underwater implosion work provided they adhere to the following guidelines:

  • Allow sufficient time to develop and tailor the technology and time of year to the particular locale and scenario – in Caltrans’ case, it took about two years;

  • Ensure that those carrying out the work possess a high level of expertise and will not cut corners;

  • Identify appropriate work windows when the least number of species may be affected;

  • Reach out early to local environmental stakeholder groups as well as resource agencies, and continue the dialogue throughout the process.

The technology behind the air curtain will be added to Caltrans’ Technical Guidance for Assessment and Mitigation of the Hydroacoustic Effects of Pile Driving on Fish. The current version provides guidance on the environmental permitting of in- and near-water pile driving projects. It includes an extensive collection of data on pile driving under a variety of conditions that can be used as an empirical reference for the permitting process.

Case Studies: Texas - TxDOT's Traffic Noise Toolkit Helps Streamline Compliance

Highway project developers in Texas responsible for compliance with traffic noise regulations now have a comprehensive collection of documents to turn to for reference, thanks to Texas DOT’s (TxDOT) online Traffic Noise Toolkit. The toolkit contains a dozen documents on topics including traffic noise regulations, compliance with the National Environmental Policy Act (NEPA), compliance with Federal Highway Administration (FHWA) requirements, and instructions for using FHWA’s Traffic Noise Model.

To assist with documentation, the toolkit includes a template letter to local officials about noise contours for land use planning as well as recommended text for documenting traffic noise analyses. And it provides direct links to relevant federal requirements and websites as well as a brochure about traffic noise abatement in both Spanish and English for public outreach.

One of a Group

The Traffic Noise Toolkit is one among a group of 17 environmental compliance toolkits developed by TxDOT’s Environmental Affairs Division. Subject matter ranges from air quality to Section 4(f) of the Department of Transportation Act to bicycle and pedestrian accommodation. Each toolkit contains background policy information, general guidance for compliance, procedures, and standards, and a variety of forms for conducting environmental compliance work and recording environmental decisions.

“Our goal in developing the toolkits was to provide a one-stop shop for information pertaining to compliance policy and guidance,” said Ray Umscheid, TxDOT’s Noise Specialist and lead for the Traffic Noise Toolkit. “These types of materials can be difficult enough to understand without having to scavenge the Internet to find them. By having all of the guidance in one location, related materials can clearly be linked and better understood.”

Compliance and the Toolkit’s Origins

Adherence to traffic noise regulations involves compliance with sections of the National Environmental Policy Act (NEPA) as well as the Federal Highway Aid Act. The latter Act mandated that FHWA develop and promulgate procedures to abate highway traffic noise and construction noise. Compliance with these procedures is a prerequisite for granting federal-aid highway funds or FHWA approvals for construction or reconstruction of a roadway. In Texas, regardless of the funding source, all projects must undergo the same process for a noise analysis and ultimately must be approved by TxDOT.

When developing the toolkit, TxDOT determined the contents and developed the draft documents. The documents then were sent to FHWA for input, revised as needed, and posted online. Umscheid said the toolkits already were under way when his agency was granted authority to assume federal NEPA responsibility from FHWA in December 2014. The toolkits will serve TxDOT well as it carries out that role, he added.

Using the Toolkit

“Traffic noise guidelines and modeling methodologies can vary widely from state to state. Because many of the consultants that perform our work are from other states, it is important to have this information readily accessible to facilitate quicker project turn-around,” explained Umscheid.

One of the toolkit’s benefits is that the documentation for complying with FHWA requirements now can be dropped directly into the documentation for complying with relevant portions of NEPA. Before the toolkit was developed, the TxDOT noise guidelines were posted online while there was an overall environmental manual posted elsewhere on the TxDOT intranet site. In the toolkit, the manual has been revised as a noise only manual which references the noise guidelines and the additional supporting documentation, which either didn’t exist or had to be e-mailed to consultants for specific situations.

Umscheid offered specific advice for those using the toolkit. He said there is an inherent hierarchy in the documents posted, with guidance documents having the most detail and therefore being the key documents for ensuring compliance. Next down in the hierarchy come the standard operating procedures documents, which ensure that procedures are performed and documented appropriately. The information posted has been specifically broken out to address the needs of many audiences and users including in-house users, TxDOT district personnel, local governments, and the public.

A substantial portion of the information in the toolkit is “Texas-specific.” FHWA’s Federal Aid Policy Guide 23 CFR 772 gives states considerable discretion on precisely how to abate construction and traffic noise. The Texas-specific information includes TxDOT policy, guidance, and procedures as well as standards for environmental studies and document production. It reflects the fact that TxDOT has several agreements with resource agencies that require certain formats for information submittals, procedures for consultation, and communication protocols.

Recently, said Umscheid, the toolkit was put to particularly good use on a US 290 project in Houston. Consultants were able to access the TxDOT Traffic Noise Model Manual online and use that reference material to help them update an older noise model so that it was consistent with the agency’s modeling methodology for its current projects. In general, the toolkit helps to ensure that all projects are as consistent as possible, that impacts are predicted accurately, and that abatement will be proposed in a similar fashion throughout the state.

Work in Progress

“While the toolkit clearly already has proven its worth, I still view the current version as a starting point… a work in progress,” said Umscheid.

From time to time, he receives feedback from TxDOT Districts and other users in the form of suggestions for additional toolkit components. The latest was a request for a blank letter template intended to inform local officials of noise impact contours. Although the requirement is directed in the federal rule, a consistent, easily accessible template aids in the effort for districts with little noise experience, he said.

In terms of whether other state DOTs can use the Traffic Noise Toolkit as a starting point for their own toolkits, Umscheid reiterated that much of the content is state-specific. However, he suggested that the general format of the kit (and its counterpart kits) may be useful.

The toolkit is continually under development as federal guidance evolves, best practices are incorporated, and questions and issues arise. Because much of the overall guidance is not prescriptive, associated documentation is easy to create and update within that structure.

One example of an anticipated change to the toolkit will be to post an updated Traffic Noise Model manual upon completion of the beta testing of the upcoming model. When available, it will include additional details regarding the modeling barriers for multilevel apartments or other special land uses.

The Federal Highway Administration has launched an interactive, online tool to support collaborative decision-making in transportation planning and project development. PlanWorks is built around key decision points in long-range planning, programming, corridor planning, and environmental review. PlanWorks suggests when and how to engage cross-disciplinary partners and stakeholder groups, and includes a decision guide, assessment tools, applications, and a resource library. The tool, formerly known in beta-version as Transportation for Communities - Advancing Projects through Partnerships (TCAPP) – is now permanently managed by FHWA. The agency also announced funding assistance to help state DOTs and metropolitan planning organizations implement the tool. The application period for funding will be open May 29 through June 26. For more information, link to PlanWorks and the Round 6 SHRP2 Implementation Assistance Program announcement. (5-14-15)

Case Studies: Utah - Utah DOT’s Web Mapping Tool Helps Link Planning, Environmental Decisions

The Utah Department of Transportation (UDOT) has developed a powerful interactive planning tool, UPlan , that provides a comprehensive data repository where users from state, local, and federal agencies and the public can share data. With this wealth of information in hand, transportation planners, as one of many user groups, can make more informed, strategic decisions that reflect a broad understanding of the potential impacts each project may have, including its environmental impacts.

“UPlan gets everyone on the same page,” said Becky Hjelm, GIS Manager at UDOT. “It’s a visual tool that connects our users to current, relevant business systems and data sets within UPlan as well as data sets outside it.”

UPlan data takes the form of hundreds of dynamic GIS web maps and apps that incorporate information from multiple datasets. For instance, transportation planners interested in environmental links to a project can simultaneously view the locations of critical environmental attributes such as streams, wetlands, rare plant habitats, and historic sites, along with maps of planned transportation projects scheduled to be carried out in the same geographic area. Users can search for data in a variety of ways.

Diverse Users

Currently, according to Hjelm, there are approximately 100 UPlan users who actively are creating content, And there are hundreds more who come to Uplan for the information they need. Users include representatives from transportation agencies, resource agencies, metropolitan planning organizations, local governments, citizen groups, and the public. A very small percentage of the data in UPlan is sensitive. Access is to sensitive data is handled in two ways, 1) by providing secure access via a login; and 2) an MOU with the responsible agency defining acceptable use. One way around the sensitive data concern is to provide what is called a buffer data set, which provides general but not precise locations.

Hjelm said one positive outcome of UDOT’s investment in web GIS development is the Utah Mapping and Information Partnership (UMIP), a coalition of Utah state agencies that includes the Department of Environmental Quality, UDOT, the Department of Public Safety, and other agencies, as well as a handful of Utah counties.

UPlan originated in 2008 when UDOT planners and engineers realized that they were spending inordinate amounts of time looking for data that was in silos and scattered across agencies. They decided that it would be well worth investing time and money to create a single location where relevant data from a wide variety of sources could be gathered and housed for convenient access.

In 2011, UDOT applied to AASHTO’s Technology Implementation Group and UPlan was accepted as a Focus Technology within its Innovation Initiative. Since then, the UPlan model has been piloted in 39 states, and a number of them have developed, or are in the process of developing, their own state-specific version of the repository.

One of the strongest benefits of UPlan, says Hjelm, is that it opens up opportunities for collaboration that did not easily exist in the past. By sharing information with partner agencies and stakeholders early in the planning process, transparency is created that can foster greater trust across agencies. It also creates conditions in which more efficient, effective, and sustainable approaches to projects can be identified.

uPEL Report

One of UPlan’s most useful applications has been its ability to identify potential environmental impacts of projects and generate what is called Utah’s Planning and Environment Linkages Report (PEL) (uPEL report). Each report summarizes all of the environmental and community resources that are intersected by a potential project’s footprint. Resource information on nearly 20 topics can be drawn upon for the analysis, such as floodplains, rare plants, Section 4(f) lands, environmental justice concerns, and historic sites. An accompanying factsheet with each report provides information related to the project needs, forecasts, conditions, and other current and planned work in the area. More information about uPEL can be found in the uPEL User Guide

Underlying each uPEL report are the collaboration and integration principles that form the basis for FHWA’s Planning and Environmental Linkages (PEL) approach to transportation decision-making. Using the approach means 1) considering environmental, community, and economic goals early in the transportation planning process; and 2) using the information, analysis, and products developed during planning to inform the environmental review process.

Hjelm cited several examples in which uPlan and uPEL have been used to great benefit. The first was the Uinta Basin Rail project in which it was used to screen 26 possible alternatives for laying approximately 4500 miles of track. What normally would have taken a few years of investigation was achieved in a few months.

In another case, uPEL was used to support analysis for a Programmatic Biological Assessment (BA) for the Utah prairie dog. UDOT conducted a GIS analysis to identify locations where Utah prairie dog habitat intersected highways using UPLAN and uPEL. Then, UDOT and the U.S. Fish and Wildlife Service conducted one single Section 7 consultation that cleared an entire sub-set of projects for a 20-year period. The Programmatic BA enabled UDOT to streamline compliance with the Endangered Species Act while helping to ensure conservation of the Utah prairie dog.

Continuous Improvement

Hjelm said that although uPEL in its current form definitely has proven its worth, UDOT is planning to overhaul the application in several significant ways. First, the format of uPEL reports is being revised so that the information can be dropped more easily into required documentation for National Environmental Policy Act compliance. In addition, changes are being made that reflect changes in the system’s data sets.

In addition, the current online User Guide is being revised to make the information more easily understood and include lessons learned. The guide explains how uPEL works, how reports are generated, and the benefits of using it as a planning tool. It also contains sections on each environmental system included in the repository (e.g., floodplains) and describes how transportation projects can affect that system, repercussions if that is the case, datasets about the system that are included in the repository, and contacts for more information.

Code Available to Other States

Hjelm said the code behind UDOT’s uPEL is being offered free to other state DOTs who are interested in creating their own PEL-type application. Although they will have to invest considerable time modifying the framework and populating it with data to fit their needs, obtaining the code “should provide a starting point.” Several other states have, or are developing, tools that are similar to uPEL, she said. Each state will have its own challenges with data sharing.

Her primary advice to other state DOTs who may be contemplating a PEL-based tool: Be bold in your thinking and be patient with the process. Sharing data and building constructive relationships with other agencies and citizen organizations sometimes can take time. But the time invested, especially at the beginning of the process, is well worth the effort over the longer term.

UPlan and uPEL will continue to evolve to reflect constantly changing circumstances, she adds. One option UDOT is exploring is the possibility of incorporating 3-D maps. The ultimate goal is to have information flow seamlessly across multiple disciplines including engineering, design, construction, operations, maintenance, and environment.

Case Studies: Oregon - Oregon DOT Makes Headway in Streamlining ESA Section 7 Consultations

The Oregon Department of Transportation (ODOT) and Federal Highway Administration (FHWA) have significantly reduced review time and cost for conducting endangered species consultations for their projects through implementation of a unique statewide programmatic consultation that streamlines procedures while ensuring conservation of potentially affected species listed under the Endangered Species Act (ESA).

ODOT’s John Raasch explains that “prior to the Federal-Aid Highway Program (FAHP) ESA programmatic consultation process, ODOT was spending six to nine months preparing a Biological Assessment and awaiting the Biological Opinion. It was expensive and time consuming. With the FAHP [programmatic ESA consultation], that consultation time is now one to two weeks. Due to the process being so efficient, ODOT can submit documents later in the project planning phase when more specific details regarding project design are available, resulting in fewer revisions and shorter review timelines.”

In the late 1990s and early 2000s, numerous west coast salmonid species (Chinook, Chum, Coho, steelhead, Sockeye and Bull Trout) were listed under the Endangered Species Act (ESA). ODOT, whose road and bridge projects border and cross a high number of salmon-supporting streams, began hiring more biologists and consultants to prepare the numerous and lengthy Biological Assessments (BAs) that were now required and to manage the ESA Section 7 consultation process.

After many years of preparing separate BAs evaluating predictable impacts and implementing similar mitigation measures, and completing separate Section 7 consultations which took on average six to nine months, ODOT and FHWA approached the US Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) about a programmatic approach to ESA Section 7 consultations for these species. Taking advantage of the collaborative and problem-solving spirit built between ODOT, FHWA, USFWS and NMFS staff biologists over the preceding years, the agencies agreed on a set of procedures and tools for implementing the Federal Highway Administration (FHWA) statewide programmatic Endangered Species Act (ESA) Section 7 consultation and Magnuson Stevens Act (MSA) consultation with NMFS and USFWS.

The FAHP programmatic consultation for Highway Projects resulted in two biological opinions (BO), one from USFWS and one from NMFS, which provide ESA coverage for the majority of highway construction projects funded by the FAHP and administered by ODOT. To qualify for the FAHP programmatic consultation, the project must:

  • Result in an ESA determination of “may affect” (likely or not likely to adversely affect) for one or more of the specified federally-listed species or designated critical habitat (CH). The FAHP programmatic authorizes “take” for species most likely to be directly impacted by highway projects including all ESA-listed fish species and associated CH in Oregon.
  • Result in a determination of “may affect” fisheries resources governed by the MSA.
  • Result in a National Environmental Policy Act (NEPA) classification of categorical exclusion or environmental assessment.
  • Not involve specific excluded activities.

Outcome-focused design standards that were agreed upon by ODOT, FHWA, NMFS and USFWS, and that provide benefits to species and their habitats, are a key to the success of the FAHP programmatic. Some examples of these outcome-focused design standards are shown in Table 1.

There are four main phases of project implementation under the FAHP programmatic: early coordination, notification, construction, and post-construction. The details of project implementation are described in the FAHP Programmatic User’s Guide. As the lead agency, FHWA administers the FAHP programmatic, which includes local and state projects within the scope of the program. Projects that require U.S. Army Corps of Engineers (USACE) permits can use the FAHP programmatic to meet USACE ESA requirements. The FAHP action area includes all geographic areas in Oregon where transportation projects directly or indirectly affect ESA-listed species covered by the FAHP programmatic.

ODOT has found that conservation, consistency and efficiency are the benefits of the FAHP programmatic:

  • Conservation: the FAHP focuses on the outcome for covered species and their habitat.
  • Consistency: the FAHP provides predictable costs, design standards, outcomes for covered ESA-listed species, and agency review timelines.
  • Efficiency: in addition to predicable FAHP permitting components, an online form consisting of check boxes, drop downs and a few short text fields replaces the 200+ page BAs previously common at ODOT.

The FAHP programmatic consultation would not be possible without the trust built between participating agencies over time. As a result of its success, NMFS and USFWS were able to defer approval responsibility to FHWA for a large portion of projects.

According to ODOT, as of late 2015, 134 projects had been completed under the programmatic since its inception, with 77 completed or in construction. About half of those projects were local agency projects, and just over half of the projects required only FHWA approval with NMFS notification.

Implementation Tools for ESA Consultations

Several tools were developed to meet the reporting requirements of the FAHP programmatic and assist with information sharing and management. These include:

  • Initiation, Notification, Construction Inspection and Completion forms.
  • Webmap – The location and status of all projects implemented using the FAHP are available for stakeholders to track via ODOT’s FAHP Projects Map. Each project is symbolized by its current status and includes a link to the project files. These contain more detailed information ranging from plan sheets to notification forms to construction monitoring reports.
  • Project Tracking – All projects that use the FAHP are documented and tracked in a centralized data management system and coordinated by ODOT. Project impacts, enhancements, and take are all tracked, and quarterly status reports are available to stakeholders.
  • User’s Guide – The FAHP user’s guide is a comprehensive review of the processes used to implement the FAHP. The user’s guide provides design standards, and detailed instructions for how to coordinate, notify, and monitor projects.

For agencies struggling with long and unpredictable ESA consultation processes, ODOT has the following advice if considering a programmatic ESA consultation:

  1. Consult with other states on successful programmatic ESA consultations that have been implemented. Look into the tools they created and data tracking they provide. See if anything can be built upon to meet your needs.
  2. Continue to build relationships with FHWA, NMFS and USFW. Without strong relationships between ODOT, FHWA, NMFS and USFW, this consultation would have been very difficult, if not impossible to obtain.
  3. Be realistic on your time frame for obtaining the programmatic ESA consultation. Ensure that you take the time to collaborate internally and externally to ensure success.

Case Studies: Ohio - Ohio DOT Programmatic Agreement Streamlines LWCF Section 6(f) Requirements

The Ohio Department of Transportation (ODOT) is cutting down its paperwork and ramping up its collaboration thanks to a unique Programmatic Agreement (PA) signed last year for compliance with Section 6(f) of the Land and Water Conservation Fund Act (LWCF). So, too, are its partners, the Federal Highway Administration (FHWA), the Ohio Department of Natural Resources (ODNR) and the National Park Service (NPS).

The PA lays out a carefully coordinated interagency process for fulfilling requirements when ODOT projects involve land protected under the LWCF. Under Section 6(f) of the law, any property that has received LWCF funding cannot be converted to non-recreational use without replacement of that land, which must be approved by NPS. Converted land must be replaced with land of equal or greater value, location, and usefulness.

“We were having a lot of trouble getting projects through the 6(f) process,” explains Erica Schneider, Assistant Environmental Administrator at ODOT. “It hadn’t been much of an issue in the past because we didn’t have many projects with 6(f) impacts. But in recent years, the number definitely started to go up. The process was taking months, even years, to finish. We knew we had to do something.”

The jointly-developed document contains a number of provisions that reduce required paperwork and eliminate unnecessary agency involvement for any project that triggers Section 6(f) compliance while still ensuring that the resource is protected. Projects involving Section 6(f) properties continue to be broken out into three levels: maintenance, temporary non-conforming use, and conversions. But under the PA, the compliance process for each level has been streamlined. For maintenance-type projects, ODOT doesn’t have to coordinate with ODNR or NPS, which saves the agency at least 30 days of review time. Moreover, impacts that constitute a temporary non-conforming use of a Section 6(f) property can be approved by ODNR, and NPS only has to be copied on the decision, again saving at least 30 days of review time.

“As for conversions, they still take considerable time in that they still have to go through ODNR and NPS,” says Schneider. “But, overall, we’re in a much better position.”

For instance, each agency now has a 30-day deadline for review, and it now is acceptable to use ODOT’s (FHWA’s) real estate appraisal process for replacement land rather than that of NPS. In addition, reviews can be conducted concurrently by ODNR and NPS if the project schedule is expedited. And purchase of the replacement property can occur after National Environmental Policy Act (NEPA) approval (it must be completed prior to final acceptance of the construction project by the engineer).

Furthermore, NPS now accepts FHWA’s documentation for Section 4(f) of the Department of Transportation Act in order to satisfy their NEPA obligations for Section 6(f), which opens the door to one of the biggest time-savers: a standardized single form the partners developed for Section 6(f) as well as Section 4(f). Having a single form means that information doesn’t have to be duplicated, and the new format makes it easier for district staff and consultants to follow and for agency staff to fill out. Also, since Section 4(f) analysis must be approved prior to Section 6(f) approval, ODOT can have all of the information readily available, conduct the Section 4(f) determination and simultaneously be working on the Section 6(f) evaluation.

“Saving time is saving money,” says Schneider. “Streamlining saves us time in the environmental process and also translates through into cost savings during construction due to factors such as inflation and project delays.”

Genesis of the PA

Schneider says that when she and her co-workers at ODOT realized something had to be done about the Section 6(f) process, they first went to their FHWA Division Office. Together, they decided that the next step was to approach NPS and ODNR, the state agency that administers Land and Water Conservation Funds in Ohio. The goal was to suggest jointly developing a process that everyone would benefit from, a process during which participants would collectively identify and integrate streamlining measures.

FHWA, as the counterpart federal agency, initially took the lead in broaching the subject with NPS. Shortly thereafter, ODOT came together with FHWA, NPS, and ODNR for initial discussions. The concept received a universal green light, after which it took about a year to get through the entire process. Initially the discussion focused on what was required by law. Then the focus shifted to how the process could be streamlined. A draft agreement was created, increasingly refined, then finalized and signed in April of 2014. Schneider describes the process as “an excellent team-building exercise,” one that improved participating agencies’ relationships with each other.

Since signing the 6(f) agreement, ODOT has used -- or is in the process of using -- the PA for five maintenance-type projects and six projects that constitute a non-conforming use. Currently, six conversion type projects are in progress. Five of them are small conversions and the sixth is a full conversion. For the latter, replacement property still is being sought.

Schneider says that ODOT has applied to take on FHWA’s environmental review authority under NEPA, but that ODOT’s new role will not affect the PA. ODOT likely will include a cover letter explaining that under NEPA assignment, ODOT will be responsible for all of FHWA’s actions and responsibilities under the Section 6(f) agreement.

Possibility for Other State DOTs

“To my knowledge, we are the first and only state with a Section 6(f) PA in place,” says Schneider. From her perspective, the concept is one that could be adopted by other state DOTs provided they have a good working relationship with their state agency responsible for administering the LWCF, and that both agencies work well with their federal counterparts, FHWA and NPS.

“NPS was great to work with throughout the process,” she continues. “They were willing to look for streamlining measures wherever the law allowed it. Unfortunately, the law is quite strict in a number of areas so our opportunities were somewhat limited.”

On September 31, 2015, the LWCF expired and Congress has yet to reauthorize it. If the law is not reauthorized, no new Section 6(f) properties can be added. But lack of reauthorization would not eliminate Section 6(f) requirements.

“Lack of reauthorization only means that for the time being, there will not be any new Section 6(f) properties,” Schneider explains. “Despite no new additions, the LWCF protections will remain in effect on all existing properties into perpetuity. So while we may not have new properties in that category to worry about, we will always have the existing group. ODNR estimates that approximately 1,430 properties across the state fall into this category. ”

Additional flexibility like the de minimis impact option developed for Section 4(f) compliance, would be helpful, according to Schneider. Such changes could offer improvements to the process as well as opportunities for enhancement of the resources involved.

“The good news,” she concludes, “is that for all those existing properties, we have our PA in place.”

Recent Developments: Report Assesses Electric Vehicles for Commercial, Nonroad Uses

The Energy Department’s Oak Ridge National Laboratory has issued a report on the potential for using electric vehicles for government, commercial, and industrial purposes. The report focuses on highway vehicles that are not personal transport; non-highway modes such as rail, watercraft, and airport support; and non-road equipment used directly or in support of other uses. The report finds that electric vehicles are poorly suited for long-haul trucking but have potential for other vehicles where savings on fuel costs could be significant, such as transit buses, school buses, regional and local delivery trucks, utility service vehicles, and refuse trucks. The report also finds that low supply and low demand is hampering the development of options for commercial fleets, and that successful development will be a long process involving research and development, manufacturing, purchasing, and new regulations.

Recent Developments: Grants Awarded to Six States for Exploring New Ways to Pay for Highways

The Federal Highway Administration has awarded six states a total of $15.5 million to figure out how to best charge drivers for miles driven rather than gasoline consumed. California, Colorado, Delaware, Missouri, Oregon, and Washington received grants through the Surface Transportation System Funding Alternatives program, established by the Fixing America's Surface Transportation Act. Coming in an era when fuel-efficient vehicles are impacting gas-tax funding for highways, the state pilot projects are intended to open the door to new sources of funding for highway design, construction, and repair.

Recent Developments: Pew Charitable Trusts Highlights Sustainable Highway of the Future

New technologies for sustainable highway development along the Alabama-Georgia border are highlighted by the Pew Charitable Trusts. The project, called The Ray, may be the world’s first road that generates its own renewable energy and income by selling power to utility companies. The project is a collaboration between the Georgia Department of Transportation and other state agencies, private companies and a family foundation that would improve stormwater management and provide facilities such as a drive-through tire safety station. A solar “tree” with 12 photovoltaic panels that serves as a charging station for electric vehicles and a drivable solar pavement that powers a visitors center on I-85 are also part of The Ray. Project developers are planning to incorporate solar road studs to collect data concerning weather and wildlife crossings that would be sent to drivers electronically.

Recent Developments: Report Looks at Electrification, Automation, Shared Mobility ‘Revolutions’

A report on the costs and benefits of three “revolutions” in transportation – vehicle electrification, automation, and shared mobility – has been issued by the UC Davis Institute of Transportation Studies. The report finds that vehicle electrification and automation could significantly increase congestion and urban sprawl, while also increasing the likelihood of missing climate change targets, unless they are combined with a shift toward shared mobility and greater use of transit and active transportation. This shift could be achieved through policies that support compact, mixed use development. Such efforts could save cities an estimated $5 trillion annually by 2050 while improving livability and helping to address climate change. For more information, link to the report. (5-15-17)

Case Studies: Arizona - Arizona DOT Champions Sustainability Using INVEST Tool

The Arizona Department of Transportation (ADOT) is using a self-evaluation tool to assess and improve its projects and programs, helping the agency integrate sustainability into virtually every component of the transportation lifecycle, including planning, design, construction, operations, and maintenance activities.

Over the last several years, ADOT increasingly has recognized the importance of delivering transportation solutions in a more sustainable manner to achieve economic, social, and environmental goals.

“After three years of progress, our Sustainable Transportation Program has reached every corner of the agency,” said Steven Olmsted with ADOT’s Office of Environmental Planning. “It has become our standard way of carrying out our work and is bringing multiple benefits.”

History and Program Structure

The roots of ADOT’s sustainability program extend back to 2012 when the agency published two planning documents that both called for sustainability to be a key objective. At that time, it also was adding sustainable land use and urban planning into its Multimodal Planning Division, and beta testing the Federal Highway Administration’s (FHWA) Infrastructure Voluntary Evaluation Sustainability Tool (INVEST).

In 2013, ADOT began incorporating sustainable practices into its project development and construction activities, “cherry-picking” successes and bringing them to the attention of managers to build internal support. For example, by addressing the storm water run-off component of a pavement project during construction, project managers could point out that heavy rains otherwise would have shortened the lifespan of the pavement an added to maintenance costs.

ADOT’s Sustainable Transportation Program was formalized in 2014 and is housed in the Environmental Planning Office, with management and oversight remaining largely centralized. Olmsted described the method as a “bottom up approach.” Since that time, the program has been working through designated milestones to ensure consistent adoption across a balance of disciplines. These have included an ADOT Resilience Program and ADOT’s 2016 Complete Transportation Handbook, which is a foundational resource to guide sustainable project development efforts. The handbook includes a set of strategies and tools to improve transportation system sustainability.

ADOT’s Administrative Services Division is the most recent agency component to be placed under the sustainability program lens. Draft policies are being developed for practices such as fuel efficiency, office recycling, and commuting, and are expected to become standard policy in 2017. Meanwhile, the agency continues to incorporate and assess best management practices for achieving sustainability in every component of the transportation lifecycle. For instance, INVEST has been used to assess the effectiveness of mobile onsite batch plants for cement production in sensitive eco-regions of the state.

Operational Focus Areas

To frame ADOT’s sustainability program for the year ahead, a roadmap containing several dozen “Operational Focus Areas” is agreed upon annually that span the agency’s work: planning, project development, operations, maintenance, and administrative activities. For 2016, focus areas included activities such as:

  • sustainable outreach to Arizona tribes,
  • upgrading the heavy equipment idling policy,
  • developing a reuse policy for millings, and
  • assisting the Transportation Research Board (TRB) in framing global sustainable transport.

Efforts also include stand-alone projects such as the Black and Green Sustainable Pavement Pilot Program. Sustainable pavement management enhances roadway safety and optimizes pavement life cycles to reduce costs, while also considering the environmental impacts of construction and material usage. Other projects are on the drawing board, including efforts related to clean energy and sustainable freight.

In addition, ADOT plans to publish a progress report on the three framework components of its FHWA Climate Resilience Pilot Project: storm water, extreme weather, and downscaling of climate data as it relates to transportation systems.

Evaluating Performance Using INVEST

ADOT has advanced its sustainability efforts in large part by pioneering the FHWA’s INVEST sustainability tool. FHWA developed INVEST to help transportation agencies incorporate the “triple bottom line” objectives of environmental, economic, and social sustainability into their programs and projects. Web-based INVEST includes four independent modules: Systems Planning for States, Systems Planning for Regions, Project Development, and Operations and Maintenance.

Using INVEST modules, agencies can self-score how well they have achieved specific sustainability goals by measuring their work against carefully chosen best practice “criteria.” Each criterion has been selected because it links to one or more components of the “triple bottom line.” For example, one criterion included in the Project Development module is ecological connectivity, while the Operations and Maintenance module includes an electrical energy efficiency criterion. In total, INVEST incorporates 81 criteria spread across the four modules.

ADOT has played a key role in the evolution of INVEST. In 2011 it participated in the INVEST Version 1.0 beta-test program. Then in 2013 and 2014, it implemented the PD module, and in 2015 and 2016 it scored and adopted the OM module. Also during 2016, it assisted with developing INVEST Version 1.2 and issued its 2nd Annual Sustainable Transportation Program Report which included the Arizona DOT Sustainability Implementation Report. Being a pilot test agency for the modules gave his agency an early lead in leveraging INVEST’s capabilities to make major strides forward in its own internal sustainability work, said Olmsted.

“We use INVEST to measure, plan, discuss, and improve,” he said. “It is a shortcut for arriving at what the current FHWA sustainable universe encompasses and helps us do more with less.”

Putting INVEST to Work

ADOT already has put INVEST to good use. In 2015, it scored 50 projects in the agency’s five-year construction program using the Project Development Module, with an initial specific focus on statewide roundabout projects. ADOT then expanded the scoring from roundabouts to projects ranging from pavement preservation to bridge deck rehabilitation to new lane miles. It was particularly interested in how green infrastructure, low-impact development, multimodal mobility, freight and Context Sensitive Solutions can be measured and defined.

Out of the projects scored, two were rated gold (50 percent of total possible points), 9 were rated silver (40 percent of total possible points), and 20 were rated bronze (30 percent of total possible points).

In 2016, ADOT’s INVEST scoring focus centered on the agency’s operations and maintenance efforts The agency received an independently scored 142 points out of a possible 210, sufficient to achieve INVEST’s highest platinum rating.

ADOT also has harnessed INVEST’s capabilities to help meet NEPA requirements. For example, the agency applied INVEST as a scoring tool for design alternatives and a public outreach tool for two Environmental Impact Statements by requesting comment during the scoping period.

Challenges Encountered

Selling the concept of sustainability inside a traditional road-building agency can be challenging, Olmsted said. And working with a self-scoring tool such as INVEST initially may be met with resistance from some managers. But by maintaining the focus on exchange of information, and with a potential to highlight successes as well as areas for improvement, managers usually transition from initial skepticism to active involvement in sustainability discussions.

Another challenge is that precise financial benefits are difficult to quantify. Comprehensive sustainable transportation is still in its infancy without the benefit of cost-benefit analysis and return on investment statistics.

Advice for DOTs

For other state DOTs interested in developing a comprehensive sustainable transportation program, Olmsted offered the following guidance:

  • Identify an internal senior-level champion early in the process.
  • Work closely with FHWA staff, who are extremely knowledgeable.
  • Be prepared to invest considerable time and effort to make the program viable.
  • Incorporate an awards program such as ADOT’s Excellence in Advancing Sustainable Project Development Award Program.
  • Carry out training on how to use INVEST for continuous improvement, and make its use a standard operating procedure.

Training on using INVEST is crucial, said Olmstead. In 2014 and 2015, his agency carried out classroom training on INVEST and also trained several local public agencies. During 2016, most sustainability training took place by having the training team “embed themselves” with individuals in their offices. In the coming years, the agency plans to continue classroom training classes as well as sponsor larger state-wide training sessions.

Case Studies: California - Caltrans Works to Advance 'Smart Mobility' Approach

Since 2010, the California Department of Transportation has been working to implement a new vision for integrating transportation and land use decisions that promises to combine a range of familiar solutions taking hold across the nation: smart growth, livability, context sensitive design, transit-oriented development, complete streets, and sustainability.

Caltrans’ “Smart Mobility 2010” framework was developed to ensure that the state’s transportation investments achieve balanced outcomes for mobility, environmental protection, social equity, and economic growth – all backed by specific performance measures.

Caltrans describes the concept as follows: “Smart Mobility moves people and freight while enhancing California’s economic, environmental, and human resources by emphasizing: convenient and safe multi-modal travel, speed suitability, accessibility, management of the circulation network, and efficient use of land.”

Developed using a smart growth program grant from the Environmental Protection Agency, the framework establishes six Smart Mobility principles to be applied based on specified place-types, each with its own set of performance measures.

The six principles are:

  • location efficiency,
  • reliable mobility,
  • health and safety,
  • environmental stewardship,
  • social equity, and
  • robust economy.

Under the Smart Mobility approach, transportation planning and design would be conducted based on seven newly established place-types: urban centers, close-in compact communities, compact communities, suburban areas, rural and agricultural lands, protected lands, and special use areas.

For each place type, performance measures would be targeted to align with the principles. Types of performance measures include the following:

  • support for sustainable growth;
  • transit mode share;
  • accessibility and connectivity;
  • multi-modal travel mobility, reliability, service quality, safety;
  • design and speed suitability;
  • pedestrian and bicycle mode share;
  • climate and energy conservation;
  • emissions reduction;
  • equitable distribution of impacts;
  • equitable distribution of access and mobility;
  • congestion effects on productivity;
  • efficient use of system resources;
  • network performance optimization; and
  • return on investment.

Interregional Blueprint Process

The plan also calls for a “transformed state transportation planning process” developed through a multimodal “Interregional Blueprint” process, incorporating transportation and land use planning efforts underway by regional and metropolitan planning organizations in the state.

California is subject to some of the nation’s most ambitious environmental and sustainability goals, including the landmark Global Warming Solutions Act (AB 32), under which the state must reduce greenhouse gas emissions to 1990 levels by 2020.

In addition, Senate Bill 375, enacted in 2008, requires regional targets for reducing greenhouse gas emissions from passenger vehicles. SB 375 – which has been touted as a possible national model for transportation planning – establishes a process and incentives for the creation of integrated regional land use, housing and transportation plans called “sustainable communities strategies.” Building on these regional efforts, SB 391 passed in October of 2009, requires that the California Transportation Plan prepared by Caltrans identify the statewide multimodal transportation system that will achieve the state’s climate change goals.

The California Interregional Blueprint, a statewide land use-transportation plan will integrate the state’s various modal plans and incorporate individual blueprints developed by regions across the state. Caltrans currently administers the California Regional Blueprint Planning Program for regional transportation planning agencies to conduct comprehensive scenario planning, bringing together a range of stakeholders to develop preferred long-range growth scenarios.

The Interregional Blueprint will incorporate the Smart Mobility principles and improve modeling and data gathering, serving as the foundation for the next update of the California Transportation Plan. The Interregional Blueprint planning process is underway.

Next Steps

A number of short-term actions will be undertaken between 2012 and 2014 to develop and test approaches to implement the Smart Mobility principles and performance measures. These include applying the framework in separate planning efforts in the northern and southern portions of the state. The agency plans to document these efforts and develop a “how-to” guide for implementation.

The vision for using the framework is described by Caltrans as follows:

  • find your place type;
  • forecast transportation needs;
  • apply Smart Mobility principles;
  • assess Smart Mobility Performance;
  • prioritize transportation investments;
  • achieve Smart Mobility.

Additional Efforts

Other efforts include a Caltrans-funded study, Improved Data and Tools for Integrated Land Use-Transportation Planning in California, which was completed in October 2012. Over a three-year period, the project team collected and analyzed data on land use-travel relationships at more than 200,000 locations in most of California. The project provided a final report as well as analytical tools for use in “sketch”-planning tools, which local and regional agencies use to assist in developing scenarios, and travel demand forecasting models, which are commonly used to analyze resulting scenarios. These products will be helpful to regional agencies in their Blueprint and sustainable community strategies and regional transportation planning, and to local governments for their planning efforts. Another significant Caltrans effort has been implementation of its complete streets directive.

Caltrans also has completed a survey, “Smart Mobility: A Survey of Current Practice and Related Research,” that looks at federal, state and regional activities to assess the current state of the practice of sustainability-oriented planning and performance measurement

Case Studies: Chicago - Chicago DOT Advances Model Sustainable Streetscape

Urban streetscapes in a major city may appear to be an unlikely environment to find leaner and greener practices. However, the Chicago Department of Transportation has shown that it is not only possible to make sustainable upgrades to city streets, but that such upgrades improve the quality of the landscape and the livability of the community in many ways.

To demonstrate the scope of sustainable practices in an urban context, Chicago DOT used a grant from the Federal Highway Administration under the Eco-Logical program to help transform an approximately 2-mile stretch of urban street on Chicago’s south side. Known as the Cermak/Blue Island Sustainable Streetscape, the project follows South Blue Island Avenue and West Cermak Road along the South Branch Chicago River. In addition to the FHWA grant, the $14 million project was funded through Tax Increment Financing, as well as grants from the Illinois Environmental Protection Agency and Midwest Generation.

Planners and designers identified several performance goals for the project. These include:

  • stormwater management,
  • water efficiency,
  • multi-modal transportation improvements,
  • energy efficiency,
  • use of recycled materials,
  • reducing the urban heat island effect,
  • air quality improvements, and
  • education, beautification, and community development.

Phase I has been completed and Phase II, a portion of South Blue Island Avenue between South Wolcott Avenue and South Western Avenue, is underway, according to Janet Attarian, Project Director for the CDOT Streetscape and Sustainable Design Program.

CDOT held a dedication ceremony on Oct. 9, 2012, to highlight the successes of Phase I of the project. In announcing the completion of the first phase, CDOT Commissioner Gabe Klein said the project “demonstrates a full range of sustainable design techniques that improve the urban ecosystem, promote economic development, increase the safety and usability of streets for all users, and build healthy communities.”

CDOT said the first phase of the project has achieved a number of sustainability goals:

Material Recycling and Innovation: the first commercial roadway application of photocatalytic cement, which cleans the surface of the roadway and removes nitrogen oxide gases from the surrounding air through a catalytic reaction driven by UV light; the recycling of more than 60 percent of all construction waste and the sourcing of more than 23 percent of all new materials from recycled content; the first installation of sidewalk concrete with 30 percent recycled content in the city; and the first installation of roadway asphalt that includes reclaimed asphalt pavement, slag, ground tire rubber, reclaimed asphalt shingles, and warm mix technology.

Stormwater Management: the project diverts up to 80 percent of the typical average annual rainfall from the combined sewer through a combination of bioswales, rain gardens, permeable pavements, and stormwater features; the creation of two public plazas that infiltrate stormwater and include seating and educational opportunities.

Water Efficiency: the elimination of the use of potable water for all landscape irrigation; the piloting of 95 drought tolerant, native plant species in bioswales, and infiltration planters to evaluate effectiveness in roadside conditions.

Energy Reduction: the project reduced the energy use of the street by 42 percent and used dark-sky friendly light fixtures; installed the first permanent wind/solar powered pedestrian lights and the first LED pedestrian light poles on a streetscape in Chicago; 76 percent of all materials used were manufactured and extracted within 500 miles of the project site; and 23 percent of all materials were within 200 miles of the project site; piloted use of microthin concrete overlay to extend pavement life and increase solar reflectance.

Urban Heat Island Effect Reduction/Air Quality: the project included high-albedo pavement surfaces to decrease the urban heat island effect, representing 40 percent of the total public right of way; provided a 131 percent increase in landscape and tree canopy cover; used ultra-low sulfur diesel fuel for construction vehicles.

Community and Education: the project developed community identity with education kiosks, a walking tour brochure, and a guide book in Spanish and English that provide a wide range of information about the sustainable best practices used in the project.

Alternative Transportation: the installation of a pedestrian refuge island in Cermak Road adjacent to Juarez Community Academy, and curb-corner extensions throughout the project, in order to improve pedestrian safety; one half mile of new bike lanes on Blue Island Avenue; improved bus stop areas with signage, shelters and lighting.

Monitoring and Evaluation: modeled and monitored stormwater best management practices to analyze design, ensure predicted performance, and determine maintenance practices; performed air quality testing to analyze photocatalytic impacts on air quality; and developed a maintenance protocol with the community to transition maintenance responsibility from the city over a two year period. For the first time, the project required that a streetscape contractor fully track and document the use of recycled content, recycled materials, and local manufacture and extraction on the project.

Site Chosen for Mix of Uses

The site was chosen because it includes a complex mix of uses that made it especially attractive for testing different design elements, according to project manager David Leopold, with Knight Engineers & Architects. The neighborhood includes a park, a high school, commercial real estate, a power plant, a brick yard, a scrap yard, a nonprofit organization, and, only a block away, residential areas.

One of the main goals of the project was to balance the needs of the all the existing users while at the same time minimizing the ecological impact of the uses, all in a limited amount of space, according to Leopold. CDOT made an effort to find opportunities for ecology “based on the limitations of our urban area,” Leopold said.

Another goal was to push the technology for sustainable infrastructure, Attarian said. As a pilot project, the design goals set a very high standard and a lot needed to be done “to make sure that [technology] would be available for us,” Attarian said. For example, for the photocatalytic cement CDOT had to find a domestic source willing and able to produce it, according to Attarian.

Another example is the high albedo pavement used in the project. The concrete mixes were developed and tested by CDOT, using slag and lighter aggregates

Key to the effort was realizing that “a single design mode can have multiple benefits,” Leopold said. As an example, bioswales are effective at trapping stormwater to reduce the amount of runoff flowing into the city sewers. They also serve as a buffer between the pedestrian space and the street. In addition, they provide habitat for birds and insects. Finally, they are attractive, serving to beautify the area and promoting economic development in the process.

In addition, the project was intended to be a laboratory to learn how to design, build, and install sustainable infrastructure. CDOT wanted to find out “what we [could] do if we try to take advantage of everything we had” in terms of innovative technologies, processes, and practices, according to Attarian.

The redesign of one streetscape provides a blueprint that can be scaled up to address stormwater issues, the urban heat island effect, and other sustainability issues throughout the entire city, both Attarian and Leopold noted. What was developed for and learned from this project will be standardized and implemented as much as possible citywide. CDOT has received information from the project’s contractor on what worked and what did not work, information that will be instructive to new efforts going forward, Attarian said.

“A big part of what we are doing is education,” Attarian said. There is education of CDOT employees on how to use the new materials and design principles. The project team is developing a set of sustainable urban infrastructure policies that will be publicly available.

In addition, public education is integral to the project. The FHWA Eco-Logical grant aided in the purchase of the hybrid wind- and solar-powered information kiosks placed along the sidewalks to provide educational material about the streetscape design.

Lessons Learned

There were several lessons learned from the design and construction of the project, according to Attarian. They include the following:

  • integrated design requires new roles within interdisciplinary design teams;
  • technology availability may not always coincide with project schedules;
  • changing “business and usual” within a public right of way requires communication with all users;
  • monitoring local pilot projects is critical for the accurate comparison of grey versus green alternatives; and
  • addressing livability issues within the public right of way involves inherently sustainable practices.

CDOT has installed the means to perform ongoing monitoring of the sustainable materials and techniques, including the monitoring of stormwater, pavement and air temperatures, and air quality. This monitoring was not required, but rather it was “what we wanted to do” to learn from the project, Attarian said.

Case Studies: Chicago - Chicago's Green Alley Program

Since 2006, the Chicago Department of Transportation has been upgrading the city’s alleys with state-of-the-art green pavement materials and designs to better manage stormwater and prevent flooding. The agency also is testing use of reflective surfaces to reduce the urban “heat island” effect, and is increasing use of recycled materials for rehabilitation of alleys. Chicago’s Green Alley program was launched to help address rainwater collecting in alleys and flooding surrounding areas. Additionally, the program helped meet goals to mitigate and adapt to the effects of climate change established in Chicago’s Climate Action Plan. Each of the city’s departments was charged with determining how climate change will affect its programs and taking action to help mitigate and adapt to the expected impacts, including increases in temperature and more frequent and severe flooding.

Chicago’s urban landscape includes more than 1,900 miles of public alleys accounting for more than 3,500 acres of impervious surface, one of the largest alley networks of any city in the world, Leopold said. Rehabilitation of the city’s alleys using green techniques offered a good starting point to help relieve environmental stresses on the city’s transportation and sewer infrastructure. Most of the aging alleys throughout the city are not connected to the city’s storm sewer system and are prone to flooding. When flooding problems occur, instead of tearing up the alley and diverting water to the sewer system, officials now install permeable surfaces that slow down the flow of water and allow natural infiltration and recharge to the groundwater below.

The Green Alley program began with five pilot projects, and soon expanded for use on a regular basis. Rehabilitation using green infrastructure practices is taking place as the need arises to upgrade existing alleys. As of the end of 2009, the city will have installed more than 100 green alley designs throughout the city. To help get the word out on its sustainable infrastructure practices, the city published the Green Alley Handbook, which describes best management practices used in the program and examples from pilot projects. The handbook describes the following types of Green Alley techniques:

  • improved drainage through proper pitching and grading of the alley;
  • use of pavement materials such as permeable pavers, permeable concrete, and permeable asphalt;
  • installation of “high albedo” pavement which is light in color and reflects sunlight away from the surface rather than absorbing and radiating heat.
  • use of recycled construction materials, including recycled concrete aggregate used in concrete mix and as a base beneath surface paving, use of slag from industrial processes as a component of concrete mix, and use of ground tire rubber in porous asphalt and reclaimed asphalt pavement in non-porous asphalt;
  • use of energy efficient, “dark sky compliant” lighting that directs light downward and reduces light pollution.

The handbook describes four applications that used different combinations of these techniques based on site conditions. These included use of green pavement materials with conventional drainage, use of full alley infiltration using permeable pavement, use of center alley infiltration using permeable pavement, and use of green pavement materials with a subsoil filtration system. It also recommends a variety of best management practices that adjacent property owners can use, including recycling, composting of yard waste and scraps, planting shade trees and native plants, use of permeable pavements and green roofs, installation of energy efficient and dark-sky lighting, and creation of naturalized detention and vegetated swales to encourage stormwater infiltration.

The agency has had some “lessons learned,” including the need for increased maintenance for the permeable surfaces. The pervious pavements need to be cleaned on a regular basis to maintain permeability, and cleaning must begin before the pavement becomes deeply clogged with debris. City officials have found they can get the job done by running their traditional street sweepers twice a year – in the fall and the spring – as part of a regular maintenance routine for the green alleys. Chicago DOT is continuing to monitor the performance of green alleys to determine whether maintenance practices are sufficient and to measure infiltration rates, pavement strength and durability, and reflective characteristics of the materials.

Case Studies: District of Columbia - District of Columbia DOT Advances Sustainable Practices Department-Wide

Environmental stewardship and sustainability efforts in the nation’s capital are continuing to advance, with the District of Columbia Department of Transportation’s (DDOT) implementation of a sustainability plan and a range of sustainable practices for the department.

DDOT’s Sustainability Plan incorporates and integrates sustainable practices throughout the department’s work, according to Faisal Hameed, Chief of the Project Development, Environment, and Sustainability Division at DDOT. The agency has established measures and targets that will be revised regularly so that DDOT can track and improve its environmental performance and increase the sustainability of the city’s transportation projects and programs.

Environmental, Social, Economic Goals

DDOT’s Sustainability Plan reflects the “triple bottom line” approach to sustainability, targeting environmental quality, social structure, and the economy.

DDOT defines a sustainable transportation as “a transportation system that provides its users with various mode choices in a balanced manner without compromising their safety, accessibility, and mobility while supporting the economy, promoting livability and protecting the environment.”

The plan identifies eight priority areas for sustainability and establishes goals, actions, measures, and targets for each. The priority areas and goals are:

  • Promoting transportation and land use linkage
  • Improving mode choices, accessibility and mobility
  • Effective cost assessments in decision-making
  • Supporting the economy
  • Improving DDOT operations and project development processes
  • Protecting the environment and conserving resources
  • Climate change adaptation
  • Promoting livability and safety

For each priority area, measures and targets are identified, such as reduction of annual greenhouse gas emissions from DDOT projects by 5 percent annually. DDOT will track each area and report annually on progress made in achieving the targets.

Sustainable Initiatives and Projects Underway

Examples of sustainable efforts include DDOT’s “Great Streets” initiative, with efforts such as the Nannie Helen Burroughs Avenue project, which won one of the first grants from the Environmental Protection Agency (EPA) under its Green Highways Partnership. DDOT employees successfully worked with EPA, the Federal Highway Administration, District Department of Environment, National Park Service, and other agency partners and the community to develop a sustainable design that improves bicycle and pedestrian safety by adding bike lanes, enhancing sidewalks, and incorporating low impact development (LID) features. Project features include bioretention areas, stormwater planters, and permeable concrete sidewalks, all of which help treat stormwater and reduce runoff into local waterways.

DDOT’s work to develop a Climate Change Adaptation Plan is another key sustainability effort. The plan will focus on developing a framework of recommendations for adapting to impacts brought on by a changing climate, especially as they relate to transportation infrastructure. DDOT has conducted workshops with the Federal Highway Administration, EPA, AASHTO, Metropolitan Washington Area Council of Governments, District Department of Environment, and various other agencies to develop this framework.

DDOT also is emerging as a national leader in bike-sharing and bicycle improvement programs, spearheaded by DDOT’s Bicycle and Pedestrian Program Manager. Over 100 bike-share stations have been installed in the city and several more are planned.

Another example is the Klingle Valley Trail project, which will address historic flooding that caused erosion of a stream and road in Rock Creek Park. Working through an interagency partnership focused on a watershed approach to mitigation, DDOT will replace the existing storm-damaged roadway with a 10-foot-wide permeable-surface multi-use trail, use LID techniques and build a consistent bioswale parallel to the trail, and conduct innovative full stream channel restoration and bank stabilization for Klingle Creek.

In addition, historic preservation goals were achieved in a sustainable manner in the reconstruction and restoration of O and P Streets in the Georgetown National Historic District.

Restoration of one and a half miles of the roadway required the excavation of more than 300,000 granite pavers and removal of historic trolley tracks. After inspecting each granite paver, more than 90 percent of the original stones were reused. Each was power washed and placed one-by-one into the new roadway base. The trolley tracks and underground appurtenances were refurbished and returned to their original locations. At the same time, the 19th century water mains were replaced. DDOT employees led the complex design and construction of the roadway features while maintaining traffic and access for residents in a street that consists of all historic houses.

Other successful efforts include DDOT’s Green Alley pilot program to demonstrate use of permeable pavement and other low impact development techniques in alleys throughout D.C., as well as the city’s LED street lights programs.

EMS Advances Sustainability

In support of its sustainability efforts, DDOT also is implementing an environmental management system (EMS), based on the International Standards Organization (ISO 14001) structure. The agency may seek ISO certification in the future, Hameed said. The EMS is being implemented in phases. As the first phase, DDOT focused on the project development and environmental review process as well as office operations.

Following the “plan-do-check-act” EMS model, DDOT’s EMS outlines the agency’s environmental policy and describes objectives, measures, and targets as well as roles and responsibilities for implementation, measuring and reporting progress, and ensuring continuous improvement.

For project development and environmental review, the plan applies to all phases of project development, including planning, preliminary engineering, environmental review, final design, construction and maintenance. It calls for incorporation of environmental features in DDOT projects and increased use of beneficial and recycled materials.

For example, under the plan, projects will set a goal to achieve a 5 percent decrease in overall emissions as well as a 5 percent decrease in greenhouse gas emissions, and at least half of all projects will include environmental components such as low impact development features and tree planting.

In addition, measures and targets are included to help streamline environmental reviews by reducing delays from environmental issues, avoiding delays in obtaining permits, and fulfilling environmental commitments on projects.

As part of the EMS implementation, environmental audits will be conducted at every phase of the project development process, and environmental commitments and mitigation will be tracked to ensure that the commitments are carried through to design and construction. The results of the reviews will be documented in an annual report, including recommendations for corrective actions.

“The idea is to monitor and evaluate environmental considerations throughout the project development process,” Hameed said. Forms must be filled out when a project is initiated, he said, and based on that form, determinations are made regarding potential environmental impacts and mitigation. That form is reviewed and approved by the Project Development, Environment, and Sustainability Division to ensure commitments are carried out.

Case Studies: District of Columbia - D.C. DOT Initiatives Turn City Roads into 'Great Streets'

The District of Columbia Department of Transportation is emerging as a leader in sustainable approaches to transportation, instituting a collection of environmental process improvements and interagency partnerships to integrate land use, transportation, environmental stewardship, and community needs. There are a wide range of initiatives underway to help build sustainable communities across the city.

One initiative, dubbed “Great Streets,” focuses on improving major road corridors in the city. The program is intended to make road improvements that promote local businesses while also enhancing communities with better pedestrian, bicycle, and transit options for “sustainable mobility,” according to a summary.

The Great Streets initiative follows five basic principles:

  • Change the public and market perceptions of the corridors through streetscape and transportation improvements, and reposition them as one of the best places to live and work, consequently expanding the city's tax base;
  • Transform roadways and intersections into environmentally friendly and usable community open spaces;
  • Change the existing "corridors" function from major vehicular arterials into streets that sustain healthy pedestrian and transit based activities, and consequently support the city's air quality and transportation agendas;
  • Transform each corridor into a place that is memorable, compelling, and desirable to visit again and again;
  • Reposition the street as a vital neighborhood asset, and thus increase the community's stake in its design, upkeep, and stewardship.

To achieve these goals, DDOT plans to spend more than $100 million over 4 years to improve public spaces in six target corridors. Partner agencies in the city include the Office of the Deputy Mayor for Planning and Economic Development, the Office of Planning, the Department of Parks and Recreation (DPR), and Neighborhood Service Coordinators.

DDOT also is a key partner in several multi-agency initiatives and projects to spur economic development, social equity, and mobility in the city. Key among them is the Anacostia Waterfront Initiative, a multi-agency effort to revitalize the areas around the waterfront of the Anacostia River. Goals of the initiative are to achieve environmentally responsible development; to unify diverse waterfront areas into commercial, residential, recreational, and open-space uses; to develop and conserve park areas; and to provide greater access to the waterfront, communities, and business corridors. Construction already has begun on a new 1.5-mile streetcar line in Anacostia, the first installment of a planned city-wide streetcar network. A series of open houses on the proposed streetcar network will be held in late October and early November.

These and many other DDOT initiatives are among a long list of actions included on the “Green D.C. Agenda,” a sustainability initiative launched by D.C. Mayor Adrian Fenty on Earth Day 2009. Topping the list are the city’s pioneering efforts to promote bicycling. On Oct. 2, D.C. officials cut the ribbon on a state-of-the-art bicycle station. The facility offers bicycle parking, rentals, repairs and accessories at the west end of Union Station and holds approximately 133 bicycles. The $4 million project was funded by the Federal Highway Administration and DDOT. The city also is home to a first-of-its-kind bicycle sharing program. Launched in 2008, the program currently offers 10 kiosks housing 100 bikes. DDOT has plans to add another 50 stations to the network.

Within DDOT, plans for achieving sustainable transportation will be implemented through a range of process improvements, including a comprehensive environmental management system. Detailed information on environmental compliance and stewardship for DDOT projects is spelled out in the new Environmental Process and Policy Manual. Early consideration of stakeholder concerns allowed DDOT to streamline the review process for the 11th Street Bridges project and earned the agency top honors for environmental streamlining in FHWA’s 2009 Environmental Excellence Awards.

Case Studies: Illinois - Illinois - Livable and Sustainable Transportation Rating System and Guide (I-LAST)

Transportation design and construction groups in Illinois have helped to design a voluntary guide intended to encourage use of sustainable practices for the transportation projects in the state. The Illinois - Livable and Sustainable Transportation Rating System and Guide (I-LAST), issued in January 2010, was developed in a cooperative effort between the Illinois Department of Transportation, the American Council of Engineering Companies–Illinois (ACEC-Illinois), and the Illinois Road and Transportation Builders Association (IRTBA). The guide – which is voluntary and “advisory in nature” – provides a description of sustainability in transportation and provides a tool for identifying and documenting sustainable practices on highway projects in the state.

The purpose of the guide is to:

  • provide a comprehensive list of practices that have the potential to bring sustainable results to highway projects;
  • establish a simple and efficient method of evaluating transportation projects with respect to livability, sustainability, and effect on the natural environment; and
  • record and recognize the use of sustainable practices in the transportation industry.

The I-LAST guide identifies the following goals of providing sustainable features in the design and construction of highway projects:

  • Minimize impacts to environmental resources
  • Minimize consumption of material resources
  • Minimize energy consumption
  • Preserve or enhance the historic, scenic and aesthetic context of a highway project
  • Integrate highway projects into the community in a way that helps to preserve and enhance community life
  • Encourage community involvement in the transportation planning process
  • Encourage integration of non-motorized means of transportation into a highway project
  • Find a balance between what is important: to the transportation function of the facility, to the community to the natural environment, and is economically sound,
  • Encourage the use of new and innovative approaches in achieving these goals.

The guide includes a checklist-based scorecard for evaluating the sustainable practices included in a highway project, with 17 separate sustainable features in eight categories:

  • Planning: context sensitive solutions, land use /community planning;
  • Design: alignment selection, context sensitive design;
  • Environmental: protect, enhance or restore wildlife communities; protect, enhance, restore native plant communities; noise abatement;
  • Water: reduce impervious area; stormwater treatment; construction practices to protect water quality;
  • Transportation: traffic operations, transit, improve bicycle and pedestrian facilities;
  • Lighting: reduced electrical consumption, stray light reduction;
  • Materials; and
  • Innovation.

For each of the 17 features, the scorecard lists activities and available points that could be earned for each activity included on a project. It also provides an explanation and resources to help users better understand how to implement each of the sustainable features.

The effort started with a desire to be more proactive on sustainability and was inspired by the GreenLITES approach developed by New York State DOT (see related case study). Industry partners worked with Illinois DOT to tailor their own system, agreeing that it would be used only on a voluntary basis. There is currently no certification or other incentive for the project scoring system, but such an approach may be added in the future.

While the I-LAST approach is voluntary, District 1 already has begun using the approach. The sustainable actions listed in the guide are already being done on many projects, but it is expected to bring awareness and encourage sustainable practices. While officials say they do not foresee a statewide mandate for the approach, it is expected to raise awareness of the types of practices that can be done.

The extent to which the Illinois guide takes hold also may be influenced by a sustainability tool currently under development by the Federal Highway Administration. The agency is in the process of developing its own rating system to provide criteria for sustainable practices.

Case Studies: Maryland - Maryland SHA Develops Decision Support Tool to Select Sustainable Solutions

A new decision support tool under development by Maryland’s State Highway Administration will help the agency quickly find cost-effective solutions to address congested travel corridors while protecting the state’s environmental resources and community quality of life.

The Model of Sustainability and Integrated Corridors, known as MOSAIC, is a new planning calculator that will allow planners to quantify sustainability data and compare alternative scenarios to make more informed decisions at the corridor level for transportation planning purposes. The tool will help planners and stakeholders to move more quickly along the project development path by providing clear and succinct assessments of the relative environmental, mobility, safety, and economic impacts of project options being considered at a low cost. MOSAIC is being jointly developed by MDSHA and the University of Maryland.

Six Sustainability Factors

The tool compares project scenarios according to six sustainability factors: mobility, safety, socioeconomics, energy and environment, natural resources, and project costs. Each factor includes multiple performance measures, totaling more than thirty measures overall. MOSAIC then produces a score for each alternative and ranks its performance in relation to the various factors.

Still in the initial phases, MOSAIC is a component of SHA’s Comprehensive Highway Corridor initiative, a program to improve transportation efficiency, safety, and sustainability in critical highway corridors. In its initial version, the tool can compare two alternative scenarios—the adding of a general purpose lane or creating grade-separated interchanges—against a “do nothing” option.

SHA used MOSAIC to plan improvements to the US 15 corridor north of Frederick, Md. The tool suggested that converting at-grade intersections to grade-separated interchanges on US 15 provided more sustainable benefits as compared to constructing additional travel lanes and was much better than the no-build scenario. Over time, MOSIAC will be upgraded to include additional multi-modal scenario options.

Data-Driven Solutions

SHA recognized the need for “incorporating data-driven sustainable solutions” into the decision-making process for transportation projects, bringing the agency to use an existing contract with the University of Maryland to develop MOSAIC, according to Eric Beckett, a regional planner with SHA.

The developers performed a comprehensive review of literature and best practices and studied state-of-the-art transportation planning strategies and tools used in various state departments of transportation. These reviews provided a baseline of what works and what is applicable for sustainability decisions.

MOSAIC requires a minimum amount of training to use and produces numeric outputs and summary reports. It also creates graphical outputs suitable for sharing with stakeholders. The user supplies data such as land use, transportation, and ecological impacts, and the various factors used in the calculation can be weighted according to policy considerations and agency priorities.

Currently, the tool is in the final stages of Phase 2, which “builds off of the original…model to include multi-modal improvements for comparison,” according to Beckett. SHA will be testing it on improvements to US 29 in the near future, Beckett said.

Ultimately, the MOSAIC tool will be integrated with the Maryland Statewide Transportation Model through SHA’s Enterprise GIS system. The Maryland Statewide Transportation Model is a multi-layer travel demand model working at national, statewide, and urban levels to forecast and analyze key measures of transportation system performance.

“Eventually the MOSAIC tool will allow us to quickly evaluate proposed road improvements and…changes to land use,” Beckett said. “We believe there is a great potential for transferability” to other state DOTs, Beckett added.

Case Studies: Massachusetts - MassDOT Advances GreenDOT Sustainability Initiative

The Massachusetts Department of Transportation (MassDOT) is continuing to make progress on sustainability initiatives, a process that began with the 2010 GreenDOT policy directive.

In 2014, the agency conducted a comprehensive review of its progress on sustainability initiatives and issued the GreenDOT Report 2014 Status Update Report. Key priorities being pursued include:

  • improving the consideration of GHG impacts in transportation planning;
  • implementation of a complete streets funding program;
  • initiating a statewide climate adaptation and vulnerability assessment;
  • development of renewable energy on MassDOT assets;
  • delivering travel demand management services;
  • improving energy efficiency of MassDOT’s fixed assets; and
  • supporting increased uptake of electric vehicles.

Improving Consideration of GHG impacts

MassDOT has been working with Metropolitan Planning Organizations for a number of years to incorporate GHG impacts of projects as a consideration when transportation projects are selected. This work has taken on new urgency with the 2015 passage of state regulation 310 CMR 60.05 which makes the consideration of GHG impacts a legal requirement.

The agency has provided metropolitan planning organizations (MPOs) with analytical tools, guidelines and training to enable the quantification of GHG impacts. It also is undertaking analysis to identify the most efficient and effective means of reducing transportation sector GHG emissions through implementing a pilot of the Federal Highway Administration’s Energy and Emissions Policy Analysis Tool and a project with UMass Amherst under the Massachusetts Cooperative Research Program.

Shannon Greenwell, MassDOT’s project lead, noted that the central challenge in this work is to develop a system of GHG impact assessment that is consistent across the Commonwealth’s MPOs and allows the quantification of GHG impacts at a relatively early stage in the project development process.

Implementing a Complete Streets Funding Program

MassDOT has been a national leader in promoting Complete Streets designs. Early efforts were recognized in the award-winning 2006 Project Development and Design Guide. More recently, MassDOT issued the 2012 Healthy Transportation Engineering Directive and supporting engineering directives that set minimum standards for accommodation of active modes of transportation.

Its pioneering efforts to promote complete streets continue with the finalization of a Complete Streets Funding Program. This program will be released in January of 2016 and will help incentivize municipalities to adopt complete streets policies and construct complete street projects.

The agency also finalized a ground breaking Separated Bike Lane Planning & Design Guide in 2015 that significantly advances bicycle facility design in the Commonwealth and aims to set new precedents for design in the United States.

MassDOT Complete Streets Engineer Luciano Rabito noted that the first projects will be ready for funding in 2016 and that MassDOT has sought to provide flexibility for all participating municipalities. “We have designed a program that will offer assistance to all municipalities large or small; urban, suburban, or rural. The program, which will be managed online, will be easy to use and keep municipalities engaged throughout the process. Based on the positive feedback we have received, we are anticipating a hugely successful program.”

Statewide Climate Adaptation and Vulnerability Assessment

MassDOT has initiated a climate vulnerability assessment to help prepare the Commonwealth for the likely impacts of climate change on transportation infrastructure.

The scope of this first phase will include mapping the full inventory of MassDOT assets; compiling and mapping climate change predictions; conducting workshops to gather data on current conditions; assessing the level of risk to individual assets and the system as a whole; developing asset vulnerability criteria; and identifying a prioritized set of high-risk hazards and high-risk assets.

Development of Renewable Energy on MassDOT’s Assets

MassDOT’s work to support increased generation of renewable energy continues. The first phase of the project to establish solar farms on underutilized areas near State Highways was completed in 2015 with the addition of five solar arrays. These projects utilize an innovative form of Power Purchase Agreement financing, under which a solar developer bears the upfront cost of the installations and operation and maintenance responsibilities, and MassDOT secures a long term agreement to purchase low cost electricity. Additional solar projects are planned, as well as a wind turbine project for a commuter rail facility.

These developments add to a range of existing renewable energy initiatives on MassDOT’s assets which include solar projects as well as a wind energy project at an MBTA facility.

The project lead, Lily Oliver, explained that MassDOT is starting to see the benefits of highway solar projects after almost 2 years of design and construction. “A lot of upfront work was required for these projects to go ahead” says Oliver. “This included a competitive procurement process, price negotiations, town and highway access permits, obtaining approvals from FHWA and securing state incentives. It is satisfying to see these projects coming online which means reduced operating costs for MassDOT and lower greenhouse gas emissions for Massachusetts,” Oliver said. (see related AASHTO case study under Energy/GHG Emissions topic)

Delivering Travel Demand Management Services

In the area of travel demand, MassDOT supports the reduction of single-occupant vehicle travel by increasing the availability and use of commuting options such as carpooling, vanpooling, transit, bicycling, and walking through its MassRIDES program.

The use of these options leads to reduced traffic congestion; improved air quality; reduced GHG emissions; and enhanced quality of life in Massachusetts. MassRIDES now serves 495,000 employees within its 335 partner organizations.

Improving Energy Efficiency of MassDOT’s Fixed Assets

MassDOT has a number of initiatives underway and planned to reduce the energy used in its buildings and other fixed assets. These include the following:

  • Energy audits and high-payback upgrades of 130 buildings covering almost 1.9 million square feet; An estimated $4.4 million dollars will be invested in upgrades to the 130 MassDOT facilities, which are expected to produce an annual saving for Massachusetts taxpayers of $500,000.
  • Installation of LED lights in the tunnels of the Metropolitan Highway System in downtown Boston. The tunnels to be covered by the project contain approximately 25,000 existing fixtures that will be replaced.
  • Upgrading the heating units that prevent the Massachusetts Bay Transportation Authority’s third rail from freezing during winter. The existing heaters are outdated, have outmoded controls, and require a large amount of electricity to power. They are turned on in late fall and remain on until spring, running 24 hours per day. The MBTA is installing efficient units that can be remotely controlled based on actual weather conditions. It is estimated that this initiative could create savings of over 39.8 million kWh and $3.4 million annually in electricity costs.

Supporting Increased Use of Electric Vehicles

Massachusetts committed to a goal of 300,000 zero emission vehicles registered in the state by 2025 under a Multi-State ZEV Action Plan. MassDOT has a number of responsibilities under its draft Massachusetts’ Zero Emission Vehicle Action Plan. They include the installation of up to 12 DC fast charging stations at locations close to State Highways within Massachusetts to provide range confidence for drivers on longer journeys and providing signage to guide drivers to charging stations.

Challenges arise when installing a new layer of refueling technology on a busy State Highway system. They include meeting rules governing the use of federal air quality funds and complying with restrictions on commercial activities near the highway. MassDOT also must work with existing lessees, utility companies and other state government agencies, all while siting the charging stations where they will be most useful to the traveling public.

Case Studies: Massachusetts - MassDOT's 'Fast-14' Bridge Replacement Project Saves Time and Money, Lessens Environmental Impacts

The replacement of one deteriorating highway bridge typically requires years of planning and construction. In 2011, Massachusetts DOT completed the replacement of 14 bridge structures on I-93 in a matter of weeks, saving time and money, improving public safety, and lessening environmental impacts.

The project, which used prefabricated, modular superstructure units, was dubbed “Fast 14” – one of several projects under MassDOT’s Accelerated Bridge Program. The project was “one of the most ambitious and innovative infrastructure projects in the nation,” according to Massachusetts Gov. Deval Patrick.

Accelerated bridge construction technologies are being advanced through the Federal Highway Administration’s Every Day Counts Initiative. Intended to address the nation’s deteriorating bridges, these new techniques are aimed at cutting costs, increasing safety, and minimizing inconvenience to travelers.

According to FHWA, by using these techniques, DOTs can reduce the time associated with traditional planning, design, and bridge construction efforts by years. In addition, the newer designs and materials produce safer, more durable bridges with longer service lives than those built using conventional techniques.

Such methods also can lessen the environmental impact of construction. Most of the bridge fabrication occurs offsite in factories rather than on the construction site, minimizing disruption to sensitive ecosystems such as wetlands. Shorter construction time also allows projects to be scheduled around critical natural cycles for plants and animals.

Ten Summer Weekends

For the Fast 14 project, MassDOT announced the awarding of a design/build contract in January 2011. The $92 million contract was for the rapid replacement of 14 deteriorated bridge superstructures on I-93 northbound and southbound in the City of Medford over ten weekends between June and August 2011. This is a fraction of the estimated four years that would have been required if conventional construction methods had been used. A traffic management plan and a comprehensive communications plan allowed MassDOT to minimize congestion and other community impacts during construction, which was limited to off-peak hours. The project was completed ahead of schedule, according to Mass DOT.

One bridge that was replaced carries I-93 northbound over Riverside Avenue in Medford. On the weekend of June 3-5, 2011, the bridge was closed to traffic Friday evening, with the I-93 traffic diverted to two lanes in each direction. The substructures required only minor repairs, allowing for the rapid replacement of the superstructure.

MassDOT used excavators to demolish the old superstructure overnight, completing the removal by Saturday morning. Then the prefabricated, modular superstructure units were installed and concrete was poured to fill in between the panels. The bridge construction was completed on Sunday at midnight, and the Interstate was open to traffic in time for the Monday morning commute. The bridge was replaced in approximately 55 hours, according to MassDOT.

Project Innovations

Fast 14 debuted several innovations, according to Michael Verseckes, a spokesman for MassDOT. Of special note is a mix of concrete that was especially formulated for this project. “It's a high-early strength concrete mix that had a shrinkage-reducing admixture. This mixture was able to reach a compressive strength of at least 2,000 psi within four hours of it being set,” said Verseckes.

“Before finalizing this mix, it went through 40 test recipes to get to where we wanted to be,” Verseckes said.

Accelerated bridge construction embraces a number of techniques, according to FHWA. Primarily, there is the prefabricated bridge elements and systems. These are bridge components that are fabricated offsite or outside of the traffic areas, transported onsite, and installed with the use of cranes or other lifting equipment. Bridge elements include decks, beams, piers, and walls. Bridge systems refer to an entire superstructure or total bridge that is lifted into place.

Another component of accelerated bridge construction is the bundling of projects. Project bundling involves assigning multiple similar improvement projects along a corridor to one contractor, such as the 14 bridges in Medford. The bundling of projects saves procurement time and leverages expertise and momentum.

A third component of accelerated bridge projects is use of the design/build contracting method. According to FHWA, conventional bidding for design and construction contracts is a time-consuming sequence of events. Under design/build, a majority of the design work and all of the construction is the responsibility of one contractor. Thus, many tasks can be performed simultaneously and errors in design can be resolved more quickly.

Model Project

Fast 14 was highlighted when MassDOT hosted FHWA’s Every Day Counts Northeast Regional Peer-to-Peer Exchange on Prefabricated Bridge Elements and Systems in July 2012. The four–day event was attended by over 100 state DOT personnel from 11 states.

“People across the country are very interested in accelerated bridge construction,” Verseckes said.

In addition, many logistical lessons were learned from Fast 14. As an example, Verseckes points out “the importance of early coordination for transporting and storing the [prefabricated bridge units], which involved working with the state police, the contractor, and MassDOT, and keeping residents of the city of Medford and travelers using I-93 informed.”

MassDOT’s Accelerated Bridge Program continues to be at the forefront of highway construction innovation. In the 2012 construction season, MassDOT had over 20 accelerated bridge projects planned or completed, according to Verseckes. In addition, work began on the state’s first "mega project," the Burns Bridge in Worcester, which carries Rt. 9 over Lake Quinsigamond. The Burns Bridge project is using the design/build accelerated delivery technique. Mega projects are those with a construction budget in excess of $100 million.

As of Sept. 1, 2012, MassDOT had reduced the number of structurally deficient bridges in the state by 19.5 percent since the baseline year of 2008.

Nationwide, FHWA reports that 44 states have deployed accelerated bridge construction methods.

Case Studies: Minnesota - MnDOT’s Corridor Investment Strategy Yields Social, Economic, Environmental Benefits

The Minnesota Department of Transportation’s (MnDOT) Corridor Investment Management Strategy (CIMS) was created with one key objective in mind: advance multimodal solutions that ensure a high return on investment while reflecting the state’s social, economic, and environmental goals.

CIMS is a system of selecting projects to be funded based on an analysis and scoring of social, environmental, and economic benefits of each project.

Challenge, Solution
“CIMS gave MnDOT the opportunity to apply a robust understanding of public return on investment to the selection of highway improvements”, said Philip Schaffner, MnDOT’s Policy Planning Director.
The MN 23 CIMS project in Duluth, MN widened and reconstructed sidewalks, realigned signals, closed driveway access points, added bus pullouts and improved lighting.

CIMS came about as a result of challenging conditions. As was the case for other state transportation agencies in 2012, MnDOT officials were dealing with increasingly constrained resources alongside a transportation system that was aging. MnDOT determined that dialog and possible collaboration with other agencies whose work intersected with theirs could help strategically leverage resources and also potentially create more sustainable systems. The result was CIMS.

To familiarize other agencies and the public with the CIMS strategy, MnDOT held a series of 16 regional meetings that spring. In February of 2013, the agency issued a $30 million solicitation that invited municipalities to apply for state highway funding for projects that offered the greatest potential to help move CIMS objectives forward and also were consistent with the Minnesota GO Vision and the Statewide Multimodal Transportation Plan. The funds were from the state trunk highway account, which is funded by a combination of state gas taxes, vehicle registration fees, and sales tax on the sale of motor vehicles.

”The Minnesota GO vision calls for transportation systems that maximize the health of people, the environment and our economy, so we knew our selection process needed to reflect the triple bottom line,” Schaffner said.

MnDOT formed an advisory group of other state agencies to help develop the project evaluation criteria and evaluate project proposals. The group included Explore Minnesota Tourism and the state’s Department of Commerce, Department of Education, Department of Employment and Economic Development, Department of Health, Department of Natural Resources, Department of Public Safety, and the Pollution Control Agency.

Evaluation Criteria

Notably, the project evaluation criteria decided upon by the advisory group were broader than strictly traditional performance factors such as direct user benefits/costs and system performance. Instead, the following criteria were applied to determine project proposal scores:

  • 60 percent: enhanced benefit-cost ratio calculation using a benefit-cost ratio analysis tool that considered the following factors:
    • social – safety, bicycle/pedestrian health effects, and noise;
    • economic – travel time, travel time reliability, vehicle operation costs, life cycle costs, and loss of agricultural land;
    • environmental – emissions (carbon dioxide plus criteria pollutants), wetland effects, and runoff.
    • 30 percent: other factors evaluated qualitatively (one example cited for each) -
      • local economic impacts – such as improving access for tourist destinations;
      • context sensitivity – such as enhancing natural, historical, archeological, and cultural resources;
      • system considerations – such as closing a gap in a trail/bikeway;
      • community health and access – such as improving access for disadvantaged populations; and
      • multimodal impacts – such as improving access to an intermodal terminal.
      • 10 percent: financial plan match – at least 10 percent of project costs are covered by non-MnDOT funding with additional points available for applications that requested less than 90 percent of project costs.

Ten projects were selected from a total of 45 applications, with project construction scheduled for either 2014 or 2015. Selected projects tended to address three types of scenarios: a solution for a significant safety issue; a low-cost operational improvement; or a multifaceted urban main/complete streets project. The projects all are either complete or were scheduled to be finished by early 2016.

Typical project components include activities such as the following:

  • curb, sewer, utility, and pavement upgrades/replacement;
  • improved sidewalks and ramps;
  • additional turn lanes and upgraded signals;
  • streetscaping (that in one case specifically is designed to reduce flooding);
  • improved pedestrian crossings and bicycling conditions; and
  • improved access to other modal nodes such as bus and rail transit or trails.

For one of the projects, an interchange was constructed that increases safety, reduces environmental impacts, and facilitates agricultural equipment crossings. Another project included a four-to-three lane conversion and construction of a roundabout to support future economic vitality.

“The $30 million in CIMS funding helped the agency leverage an additional $65 million in other federal, state and local funding for a total construction program of almost $100 million,” Schaffner said.

Lessons and Reflections

The use of an enhanced benefit-cost analysis helped MnDOT translate broad goals into comparable and common metrics. The methodology allowed the review committee to compare a range of project types using one set of criteria.

“One of the benefits of the CIMS approach was that environmental impacts, particularly runoff, were elevated in importance and considered when selecting projects,” Schaffner said.

However, not all of the measures made much of a difference in project selection. For example, lack of data and forecasting methodologies meant that the health impacts of biking and walking were often missing from applications and, even when included, they usually were small relative to other factors.

“The 2013 CIMS solicitation was an incredible learning opportunity for MnDOT,” he said. “We have incorporated some of the measures into our standard guidance for benefit-cost analysis, we’re continuing to study and refine the methodology for other measures, and we’re using the solicitation as a template for other competitive grant programs.”

In terms of advice for other transportation agencies that might be interested in a similar approach, Schaffner recommended working with other agencies to develop scoring criteria “to ensure they are understandable and customized to the local context.”

Case Studies: New York - GreenLITES Certification Offers Incentive for Sustainable Practices

New York State Department of Transportation is pioneering an effort to measure its own performance on sustainability and is also creating a powerful incentive for its employees to go green. NYSDOT’s Green Leadership in Transportation and Environmental Sustainability (GreenLITES) program, launched in September 2008 and continuing to evolve, is a certification program that recognizes projects and operations that incorporate sustainable practices. The more green practices performed, the higher the certification level that can be achieved.

The first program of its kind in the nation used to rate all DOT projects, GreenLITES is modeled after the building industry’s Leadership in Energy and Environmental Design (LEED) certification program for green building practices and the University of Washington’s Greenroads program. GreenLITES applies a similar approach to recognize and encourage environmentally sustainable practices in transportation. The GreenLITES rating system tracks specific sustainable practices and awards credits based on the degree to which such practices are implemented. The system recognizes varying certification levels, with the highest level going to those efforts that go above and beyond standard practice and “clearly advance the state of sustainable transportation solutions.” Depending on the cumulative score acquired by incorporating sustainable choices into project design or operations, one of the following GreenLITES certification levels may be assigned:

  • Certified: Certification is awarded for incorporation of a number of sustainable choices.
  • Silver: Silver certification is awarded for incorporation of a number of sustainable choices with several of these choices having a high level of impact, or having advanced the state of practice.
  • Gold: Gold certification is awarded for incorporation of a substantial number of sustainable choices with many of these choices having a high level of impact, or having advanced the state of practice.
  • Evergreen: Evergreen certification is awarded for incorporation of the highest number of sustainable choices with many of these choices having an extremely high level of impact. Additionally, these efforts may advance the state of practice or are innovative in the way environmental sustainability is approached.

Scoring Projects and Operations
For Project Design, each project is tracked on a “scorecard” that lists and scores more than 170 practices in categories including sustainable sites, water quality, materials and resources, energy and atmosphere, and additional innovations and other actions. For each category, a list of activities is provided along with the number of credits that may be earned.

Because of the different nature of its work, the Operations Program takes a slightly different approach, incorporating GreenLITES sustainability measures into its existing annual maintenance and operations planning process. The long list of 130 operations and maintenance practices includes GreenLITES measures and other “green” practices available for credits in the following general categories:

  • Bridges
  • Drainage
  • Snow and Ice
  • Intelligent Transportation Systems (ITS)
  • Guiderail & Fencing
  • Signs
  • Walls and Rock Slopes
  • Multimodal & ADA
  • Pavement
  • Signals & Lighting
  • Facilities
  • Roadside Environmental
  • Markings
  • Fleet Administration
  • Communications Technology & Emergency Preparedness
  • Other

The scoring is conducted each year at the end of March at the close of NYSDOT’s fiscal year. For both Operations and Project Design, the Department presents Evergreen and Gold awards each April on Earth Day.

The program has been implemented in stages, starting with the September 2008 GreenLITES Project Design Program, followed by the April 2009 GreenLITES Maintenance/Operations Plan Spreadsheet, the March 2010 Regional Sustainability Assessment tool and the Planning, Project Solicitation tool. The Department has also launched a Local Projects Certification Program that allows other state agencies, authorities, municipalities, and non-governmental organizations to use the GreenLITES project design tool.

The GreenLITES project design tool and operations tool have proved to be good for evaluating projects that are part of an existing construction or maintenance program. However, the Department also needed a way to select the “right projects.” This led to the development of the 2010 Project Solicitation Tool and the Regional Sustainability Assessment Table.

The project solicitation tool is a questionnaire that helps determine how closely a project is consistent with seven identified sustainability goals. Points are awarded for each goal criterion in the proposed project. Project scores may then be used as a discussion point when deciding what projects to include in long-term capital program submissions.

The Regional Sustainability Assessment Table is used by NYSDOT regions to develop and assess regional long-term sustainability goals from a more holistic perspective, across program areas and using the triple bottom line realms of economy, environment and communities. The table is used to identify current states, desired future states, and plans for accomplishing future states in all three sustainability realms as they relate to specific NYSDOT goals.

All these tools are continually being updated and refined. For example, the Department is currently using the 2.1.0 project design scorecard, and after each round of operations awards the operations plan spreadsheet is updated. Also, NYSDOT is currently working on how to better integrate sustainability into the Department’s asset management and program update processes.

“The Department of Transportation is more than concrete, asphalt and steel. We are, in fact, a vital connection to and part of the path toward economic recovery,” NYSDOT Commissioner Joan McDonald said in announcing the 2011 awards. “As we plan for the future, our transportation investments must be done in a manner that is both environmentally sensitive and sustainable. GreenLITES is the Department’s nationally recognized program which keeps us focused on making transportation decisions that support a sustainable society.”

Case Studies: North Carolina - NCDOT's Accountability Framework: A Blueprint for Sustainability

The North Carolina Department of Transportation (NCDOT) has been working to integrate the concepts of sustainability into its decision-making and make the link between mobility and how it can better support communities and regions across the state. The effort has resulted in the articulation of eight principles with corresponding outcomes, objectives, and performance measures. The eight principles focus on: moving people and goods; choices; connectivity; resource protection; prosperity; accountability; healthy communities; and organizational responsibility.

The initiative began with an extensive review of sustainability plans across state departments of transportation. The purpose of the review was to identify and synthesize the best practices in integrating the concept of sustainability into transportation decision-making, with a specific emphasis on state DOTs that have developed documented plans and performance measures. Following this review, an internal NCDOT survey was conducted to identify existing sustainable practices and better understand how the department views the concept of "sustainability."

Focus groups with agency staff and interviews with external stakeholders -- including other state agencies, metropolitan planning organizations/regional planning organizations, councils of government, transit service providers, and private industry partners -- were used to present and discuss the concept of sustainability, identify additional practices and initiatives that align with those concepts, and shape the subsequent principles and objectives that were the foundation of the framework. The department then identified metrics that would be used to assess consistency and progress in meeting outcomes associated with each of the principles.

Expanded Mission Statement

Integration of the concepts of sustainability are reflected in NCDOT's newly expanded mission statement: “Connecting people and places safely and efficiently, with accountability and environmental sensitivity, to enhance the economy, health and well-being of North Carolina.” The Department's mission was expanded and refined to recognize broadened responsibilities and aspirations, and now emphasizes a "triple bottom line" of enhancing economic development, human health and well-being, and environmental resource stewardship.

The principles have also been integrated into NCDOT's statewide transportation plan (2040 Plan) and its draft 5-year and 10-year transportation improvement program (“Policy to Projects”). Efforts are also underway to evaluate project prioritization criteria and consider ways to integrate sustainability concepts in the project prioritization process.

The effort has culminated in the development of an “Accountability Framework” that links sustainability-related principles to key overarching plans and policies, strategies, and performance measures to monitor implementation progress and effectiveness over time. Further integration of these concepts into initiatives and decision-making is key to implementation. Other critical implementation elements include a communications plan, monitoring, and continuous improvement.

“Our goal from the start was to develop a viable framework for our department, and also document the methodology for its development, the mid-course adjustments, and lessons learned,” said Julie Hunkins, Manager of the Quality Enhancement Unit with NCDOT.

Sustainability at Work in North Carolina

A recent example of sustainability at work in NCDOT is the project to replace a 69-year-old bridge, which carries US 17 over the New River. As part of the project, NCDOT demolished the old bridge and donated nearly 8,000 tons of rubble, concrete, and metal to an effort by multiple state and local partners to build a new artificial reef in the New River near Jacksonville.

“This is a great way for NCDOT to live out its mission, which includes environmental sensitivity,” said NCDOT Assistant Resident Engineer Jimmy Zepeda, who is overseeing the bridge replacement project. “By reusing this material instead of putting it in a landfill, we helped form a vibrant habitat where aquatic life now lives and grows.” Recycling and reusing the material also saved the department as much as $590,000 in costs to dispose of the debris in a landfill.

Case Studies: Ohio - Ohio DOT Innerbelt Bridge Project: A Commitment to Sustainability

In February 2009, the Ohio Department of Transportation (DOT) initiated the first of two projects designed to replace the aging steel truss bridge that carries Interstate 90 over the Cuyahoga River Valley and into Cleveland’s central business district. The first Innerbelt project, developing a new westbound bridge adjacent to the existing bridge, demonstrates how Ohio DOT is working to make its major transportation investments sustainable by reducing cost, maximizing benefits, and conserving resources.

The Innerbelt project team committed to achieving sustainability goals in seven categories, which have been dubbed the “Green 7.” These include:

1. energy and energy efficiency;

2. community environment;

3. green building;

4. waste reduction and recycling;

5. green project administration;

6. materials and resources; and

7. construction practices.

ODOT's Commitment to Sustainability

The Innerbelt project’s design and construction team found several ways to cut project costs while conserving resources and getting the bridge built faster. Progress toward achieving these goals is documented in Monthly Sustainability Summaries posted on the agency’s website. For example, as of Oct. 31, 2012, the agency reported the following achievements:

  • Construction Vehicle Fuel Savings: By using construction vehicles with greater load-carrying capacity, the project has documented savings of over 85,000 gallons of diesel fuel.
  • Carbon Emissions Reductions: By reducing the fuel usage during earthmoving, the project team has saved more than 1,074 metric tons of CO2 emissions.
  • Materials Recycling: The demolition debris from the project is processed and sorted and more than half of all materials are recycled. The project team has recycled almost 5 million pounds of steel, preventing more than 123,000 cubic yards of waste from entering landfills.
  • Smaller Bridge Footprint - By using a creative bridge design that featured a modified alignment from the one originally proposed, the project team was able to reduce the amount of earthwork needed during construction by about 35,000 cubic yards and decrease the amount of steel and other materials needed to build the bridge.

Other examples of sustainability on the project include construction of a pair of “pocket habitats” under the new span of the bridge. These areas allow growth of native plants and provide a safe haven for migrating fish. In addition, the project team is relocating Peregrine Falcons that made their home beneath the existing bridge.

Based on these and other attributes, Ohio DOT has used the Federal Highway Administration’s INVEST sustainability self-assessment tool to give the project a “gold” rating.

Case Studies: Oregon - Oregon DOT Advances Sustainability Planning, Practices

A pioneer in sustainable transportation, the Oregon Department of Transportation (ODOT) was the first state transportation agency to adopt an agency-wide sustainability plan. Issued in 2004, that plan stressed inclusion of sustainability considerations in the update of the Oregon Transportation Plan, implementation of a sustainable bridge delivery program (OTIA III), and development of an environmental management system for ODOT’s maintenance yards.

In 2008, ODOT embarked on a broader three-volume sustainability plan aimed at addressing both internal and external operations in seven focus areas: health and safety; social responsibility/workforce we
