Stream Corridor Protection

Stream corridors typically include the stream bed and banks, the 100-year floodplain, and adjacent steep slopes. Vegetated stream corridors (or buffers) help filter pollutants from stormwater runoff, slow the speed at which runoff enters a stream (thereby reducing flooding downstream), reduce erosion and sedimentation, provide shade to the water, and provide habitat for wildlife.

Municipalities have many options to protect stream corridors. For example, they can adopt a stream-corridor overlay zone as part of the zoning ordinance, or revise zoning and/or site plan review regulations to include minimum setback requirements from streams.

Additionally, community groups, nonprofits, and interested citizens can plant native vegetation, such as willow cuttings, along streambanks to stabilize soils and protect water quality.

Municipalities and community groups could work together to acquire land or easements along streams to create scenic streamside greenways for their residents to recreate along and enjoy.
