Air Quality

This website provides information on FHWA's air quality programs, including transportation conformity, air toxics, and the Congestion Mitigation and Air Quality Improvement (CMAQ) program.

Community Impacts

Transportation investments have major influences on society, with significant economic and social consequences. The community impact assessment process alerts transportation planners, decisionmakers, and stakeholders to the likely consequences of a project, and ensures that human values and concerns receive proper attention during project development. Several Federal regulations support the need for a process to evaluate impacts on the human environment. The following resources are available to provide additional information on community impact assessments:

Hazardous Waste & Brownfields

Brownfields are abandoned, idled, or under-used commercial, industrial, and institutional properties where redevelopment and reuse are complicated by light to moderate contamination from hazardous substances and wastes. These properties are most often in urban areas previously used by industrial and commercial operations that generated waste materials. The following resources are available to provide additional information on Hazardous Waste and Brownfields:

Noise

This website provides information on FHWA’s highway traffic noise programs, including Noise Compatible Planning, Source Controls, and Highway Project Noise Mitigation.

Section 6(f)

Section 6(f) of the Land and Water Conservation Act requires that the conversion of lands or facilities acquired with Land and Water Conservation Act funds be coordinated with the Department of Interior. The following resources are available to provide additional information.

Visual Impacts

The public nature and visual importance of our highways necessitates that visual impacts-beneficial as well as adverse-be adequately assessed and considered when a highway project is developed. Public concern over adverse visual impacts can be a major source of project opposition. Highway agencies can help to resolve these controversies by assessing visual impacts, determining the effectiveness of mitigation measures, and incorporating any opportunities for enhancing the visual experience of both travelers and neighbors in the design of their facilities. These guidelines represent the FHWA's current thinking about best practices on this topic.
