Stormwater Management

Stormwater is water which runs off of impervious surfaces such as parking lots, roof tops, driveways and roadways during and after a storm. In many areas of Amherst stormwater enters into the town stormwater system consisting of the catch basins, pipes, culverts, and outfalls that carry the water to a discharge point. This system is maintained by the Amherst Department of Public Works. 

Beginning in 2019, the Town will be working to implement a Stormwater Management Program designed by the Department of Public Works to meet requirements of the U.S. Environmental Protection Agency (EPA) National Pollutant Discharge Elimination System (NPDES) Stormwater Phase II MS4 General Permit. Unlike some neighboring communities who began the MS4 permitting process in 2003, Amherst has only been required to comply more recently under the EPA’s 2016 MS4 general permit.
