BACKGROUND
The American Association of State Highway and Transportation Officials (AASHTO) Committee on Environment and Sustainability is called on periodically to provide information needed by state departments of transportation (DOTs) to establish policies or positions on environmental issues associated with the nation's transportation system. When new or revised federal transportation environmental and planning regulations are proposed or finalized, research is often required to develop new methods, processes, and procedures to ensure their effective and timely implementation by state DOTs. NCHRP Project 25-25 was created to respond to these needs. NCHRP Project 25-25 was a quick-response research program, designed to develop improvements to analytical methods, decision-support tools, procedures, and techniques employed by environmental practitioners in environmental streamlining, environmental stewardship, transportation planning, program delivery, and project development.
Research performed under this program covered a wide variety of environmental topics including air quality, climate change, cultural and historic resources, National Environmental Policy Act requirements, noise, environmental stewardship, threatened or endangered species, water quality, wetlands, and others. A list of completed NCHRP 25-25 research is available at https://www.trb.org/Projects/FindaProject.aspx.
