The Center for Environmental Excellence by AASHTO Communities of Practice (COPs) provide forums for invited professionals to discuss and exchange information, experiences, ideas, and best practices on a range of environmental topics related to the planning, design, construction, maintenance, and operation of highway and transit systems. The goal of these Communities of Practice is to promote environmental stewardship and to encourage innovative ways to streamline the transportation delivery process.
Communities of Practice currently exist for the following four topic areas:
Individual Community of Practice discussions are facilitated and moderated by Center technical experts. Typically, the communities participate in regular conference calls, exchange emails, share experiences, and provide input to and review of state-of-the practice reports, which are prepared periodically by the CoP facilitator in cooperation with CoP participants.
In addition to conference calls and emails, the Historic Bridges CoP has been beta testing an online forum since April 2009. The online forum includes discussion threads, a resource library, a list of participants, a glossary, web links and a virtual suggestion box.
Community of Practice members participate as individual members of the community and do not necessarily represent their agency's views or positions. In addition, the discussions of the CoP and the contents of the materials it generates do not necessarily represent the views or positions of AASHTO or the Center for Environmental Excellence.
If you have questions or comments regarding the Community of Practice forum, please contact the Center for Environmental Excellence by AASHTO through the Contact Us link.
The purpose of the Air Quality COP is to assemble a group of State Department of Transportation (DOT) air quality practitioners to have a focused discussion on the state of the practice, emerging issues, and research data needs on particular air quality issues. Practitioners share experiences and learn from each other, helping to further the state of the knowledge of the community. In addition, the effort helps to extend the COP members' networks and professional contacts. The Air Quality COP consists of representatives from ten State DOTs, the Federal Highway Administration (FHWA), the Federal Transportation Administration (FTA) and AASHTO. COP reports may be accessed below:
The Environmental Justice (EJ) Community of Practice (CoP) is a forum for DOT and metropolitan planning organization (MPO) practitioners to hold regular discussions regarding EJ emerging issues, and analyze the state of the practice and its implementation. Building upon previous Center work on EJ issues, the EJ CoP will identify themes on which to focus and hold discussions. Participants are encouraged to engage in other EJ opportunities and share lessons learned with the larger group. AASHTO staff and other partner organizations will work to facilitate the increase of technical assistance offerings and coordination between state DOTs and MPOs.

The Historic Bridges Community of Practice helps identify emerging issues, trends, procedures, research, and data needs associated with the identification, evaluation, and management of our nation's historic bridges. This Community of Practice also contributes to current discussions on how to effectively preserve and manage the nation's highway bridge assets, since historic bridges are a critical component of our country's transportation infrastructure. Individuals invited to participate in this Community of Practice include bridge engineers and historic preservation professionals from public and private sectors and academia.
The Historic Bridge COP has been beta testing an online forum since April 2009. The online forum includes discussion threads, a resource library, a list of participants, a glossary, web links and a virtual suggestion box.
The following State-of-the-Practice Reports have been prepared by the COP facilitator in cooperation with COP participants:
The Stormwater Management CoP is a forum where State Department of Transportation (DOT) practitioners can engage in facilitated discussions on emerging issues, research data needs, and innovative stormwater quality compliance solutions. Practitioners share experiences and learn from each other, helping to further the state of the knowledge of the community. In addition, the effort helps to extend the COP members' networks and professional contacts. The work of the COP is a continuation of efforts that were initiated in June, 2008 at the first AASHTO National Stormwater Conference in San Diego, California.
The Stormwater Management CoP consists of representatives from sixteen state DOTs, the Federal Highway Administration (FHWA), the Federal Transportation Administration (FTA) and AASHTO.
In June 2009, a state-of-the practice report was prepared by the COP facilitator in cooperation with COP participants. Additional state-of-the-practice reports were prepared in March 2010 on total maximum daily loads (TMDLs) and on EPA's effluent limitation guidelines for construction and development projects. The January 2011 COP report focuses on EPA's post-construction stormwater control rulemaking.
