Highways create a multitude of impacts on wildlife movement across the landscape. Some of the highway impacts result from the structure of the roadway, location of the roadway, traffic volume,
Over the last decade, natural resource agencies and transportation agencies have become increasingly aware of the effects that highway and railroad systems have on wildlife. Habitat loss and fragmentation are
Monitor different crossing structures to determine which kinds work best. TERI Administrator Note (June 2007): Research Completed (See Below) NCHRP – Evaluation of the Use and Effectiveness of Wildlife Crossings,
Recent federal legislation, rules and other initiatives (SAFETEA-LU, executive orders, Eco-Logical, Green Infrastructure, etc.) encourage and in some cases require state Departments of Transportation to increase their levels of collaboration
Development and implementation of multi-state plans/strategies for relocation of endangered freshwater mussels from thriving source populations to rivers within the historical range of these species for the purposes of augmentation
Many local rural roads were designed to provide land access, with little thought given to high traffic or heavy loadings. In some areas this includes higher classified “farm to market”
The research will examines the links between where people live and how that affects their access to employment, transport and a range of services; and considers the implications of housing
TERI Database Administrator Notes. Not recommended at present time by 2009 Natural Systems Subcommittee. FHWA is currently establishing a 100 acre native grassland planting along I-35. We do not have
TERI Database Administrator Notes. Not recommended at present time by 2009 Natural Systems Subcommittee. Subcommitee sees this topic as consistent with ID#86. A state of the practice survey and gap
Alternative power lighting shows great potential for reducing energy consumption. At this time, there is little to no analysis available from actual implementation of such systems for highway lighting. Viability
Conventional structural systems do not meet the objectives of environmental stewardship including full use of recycled materials, minimizing labor costs, expedited construction, and a fully recycled system at the end
The Pagosa skyrocket (Ipomopsis polyantha) is a rare plant, endemic to Mancos shale soils, and found only in and around Pagosa Springs in Archuleta County, Colorado. Plants are between 1
The southeastern United States is the center of biodiversity for freshwater fishes and mussels in North America. Many of these species are imperiled and one of the leading causes of imperilment
Assess management efforts to prevent or slow the spread of exotic plants into and away from roadsides. Research should stratify sites based upon ecosystem, soil fertility and time of disturbance.
Project Description: With culverts installed in numerous locations throughout southern California to allow for hydrological flow under roadways, they also provide the secondary function of vagile species connectivity to habitat
Background: This research proposal seeks to study Portland Cement Pervious Concrete’s (PCPC) ability to remove pollutants, particularly heavy metals, and reduce surface volume flows from highway runoff. This study will
Background: Natural and engineered dispersion are best management practices (BMPs) designed to receive highway runoff from sheet flow for the purposes of water quality treatment and flow control. These BMPs
Research Idea Scope: Background: Petroleum hydrocarbon pollutants are present in stormwater runoff at most transportation facilities, and reducing their levels is a common requirement in National Pollutant Discharge Elimination System
General Scope of Work: Task 1: Literature Review. Complete a literature review to determine the sources of zinc in highway runoff. The literature review should also attempt to determine if
Stormwater treatment of bridge deck runoff has always been a tough design challenge. Traditional methods of treating bridge deck runoff suggest piping stormwater off the bridge and treating it on
This study will develop a compost blended with phosphorus sorption media mix (Mix), which will treat highways stormwater runoff while limiting phosphorus leaching. Compost effectively removes metals and other pollutants
