Environmental Sensitivity

By its very nature, the transportation infrastructure (roads, bridges, nonmotorized pathways, transit routes, and facilities) and the people and vehicles that use it impact the environment - both natural and built. It is important to consider this interaction when planning, designing, constructing, and maintaining the transportation system. With that in mind, SEMCOG has developed a regional analysis of the impact of planned transportation projects on the environment and a series of guidelines for mitigating impacts.

This site is dedicated to assisting road and transit agencies with the integration of environmental issues in the transportation planning process. Please check back often for the most current information.
