Stormwater Management

What is Stormwater?

Stormwater is water that originates from precipitation. Stormwater that does not soak into the soil or remain on the surface and evaporate becomes stormwater runoff.

Stormwater can pick up debris, chemicals, dirt, and other pollutants and flow into a storm sewer system or directly to a lagoon, pond, wetland, or coastal water. Anything that enters a storm sewer system is discharged untreated into the waterbodies we use for swimming, fishing, and recreation.

Polluted stormwater runoff can have many adverse effects on plants, fish, animals, and people.

The Town's strives to protect surrounding water bodies and enhance the natural resources by improving water quality through the promotion and implementation of effective stormwater management practices, regulation of land development, collaboration with regional jurisdictions, along with public education and outreach through its Stormwater Management Program.
