Capture Stormwater

Rainwater and snowmelt run off our roadways, lawns, and construction sites into catch basins on the streets carrying fertilizers, oil, and trash that pollute our waterways. Education is imperative to preventing pollution of our streams, rivers, and ponds. Often times residents are unaware of the direct connection between what they use on their lawns or what they dump down stormdrains and the health of the environment.

Preventing Stormwater Pollution

Like most towns in Massachusetts, Dedham faces a problem with stormwater pollution. Runoff from our parking lots, roads, sidewalks, and other hard surfaces carries pollution into our water bodies. This pollution can make water bodies unsightly, and unsafe for swimming, boating, fishing, and other recreational activities. 

Dedham is working towards a cleaner future by providing educational resources for its residents on how to prevent stormwater pollution. Through our partnership with neighboring towns and the Neponset River Watershed Association we are tackling stormwater pollution. 

For more information on what Dedham is doing and how you can be part of the solution view the Dedham Stormwater Best Management Practices Flyer

Stormwater Management Plan (SWMP)

Below is a copy of our annual Stormwater Management Plan. Each year as part of our MS4 permit we are required to update and revise the plan accordingly to meet the requirements of our permit.

Town of Dedham MS4 Stormwater Reports

Stormwater runoff is the leading cause of water pollution in New England. It may threaten drinking water or impact water quality keeping residents from safely swimming and fishing in local ponds, lakes and oceans. The Town of Dedham submits to EPA an annual report detailing the Town's progress in addressing stormwater.

Stormdrain Stenciling Program

The Dedham Conservation Commission and Environmental Department have developed a stormwater education program designed for school groups and scout troops. The goal of this program is to educate Dedham youth and foster the next generation of environmental stewards through fun, hands on projects. Youth will participate by stenciling on the curb of stormdrains “Do Not Dump, Drains to Charles River" or “Do Not Dump, Drains to Mother Brook”.  Through hands-on educational activities students will learn how to reduce pollution and protect our natural resources.
