What is the purpose of the stormwater bylaw?

The bylaw’s purpose is to reduce pollutants in stormwater runoff. Stormwater is rain or snowmelt which empties into street catch basins and flows via pipes into local water bodies like Pine Tree and Unquity Brooks, and eventually into the Neponset River, which flows to Dorchester Bay and the Atlantic Ocean. Unlike wastewater, stormwater is not treated. As it flows over roofs, lawns, and paved surfaces like driveways and streets, stormwater picks up pollutants such as sediment, soil, pet waste, fertilizer and pesticide residue and carries them to local rivers and streams.
