Congestion Mitigation and Air Quality Improvement program

The Congestion Mitigation and Air Quality Improvement program (CMAQ) encourages transportation projects that improve air quality. It includes efforts to enhance public transit, bicycle/pedestrian facilities, ridesharing programs and facilities, and technologies that improve traffic flow and vehicle emissions.

CMAQ funds are only available in these southeastern and northeastern Wisconsin non-attainment and maintenance counties: Milwaukee, Racine, Kenosha, Waukesha, Washington, Ozaukee, Walworth, Sheboygan, Kewaunee, Manitowoc and Door. The department solicits applications every other year.

CMAQ funding was continued pursuant to Moving Ahead for Progress in the 21st Century (MAP-21), the federal transportation act that was signed into law on July 6, 2012. MAP-21 provisions took effect on October 1, 2012. Generally, projects eligible for CMAQ funding pursuant to SAFETEA-LU remain eligible for funding under current legislation. MAP-21 continues to emphasize cost-effective projects, and legislation prioritizes certain projects such as those that reduce particulate matter emissions in areas of nonattainment for this criteria pollutant.
