MDOT's Noise Abatement Program is a resource for local governing authorities and Michigan residents seeking information regarding the mitigation (reduction) of motor vehicle noise.
MDOT maintains over 10,000 miles of roads and their associated drainage systems. While this transportation network supports extensive commerce and travel, it also accumulates contaminants from vehicles, road construction, maintenance and adjacent contributing drainage areas. MDOT does business so that stormwater pollution is reduced or eliminated.
The National Environmental Policy Act (NEPA) established a national environmental policy and goals for the protection, maintenance and enhancement of the environment. It requires agencies like MDOT to assess the environmental effects of their proposed actions prior to making decisions. Using the NEPA process, MDOT evaluates the environmental and related social and economic effects of their proposed actions.
