A restored stretch of Doan Brook with stabilized banks and widened floodplain.

Stormwater is any rainwater or melting snow or ice that flows over the surface of the land to the nearest sewers, lake, or stream. Hard surfaces like driveways, roofs, parking lots, and even some lawns pose two stormwater problems: Pollution (which the stormwater carries to its destination untreated), and increased flow (surface runoff flows quickly and in larger volumes, contributing to flooding and erosion).

Our Regional Stormwater Management Program helps address flooding, erosion, and water quality problems, and customers can take actions on their property to reduce the impacts of stormwater runoff while saving money in the process.
