What is Stormwater

Stormwater is precipitation (rain or snow) that travels across:

  • Driveways
  • Lawns
  • Parking lots
  • Roads
  • Roofs

What Does Stormwater Picks Up

Stormwater can pick up:

  • Fertilizers
  • Litter
  • Nutrients
  • Oil
  • Pathogens
  • Pesticides
  • Sediment

Where Does Stormwater Go

It moves across impermeable and semi-impermeable surfaces; resulting in polluted runoff. Eventually this runoff makes its way into our lakes, rivers, streams and estuaries, and since it is often contaminated with pollutants, is one of the major contributors to water pollution in the United States, and of special concern to waters such as the Long Island Sound and the South Shore Estuary Reserve which surround the Town of Brookhaven.


Polluted stormwater runoff, also known as non-point source pollution, often results in:

  • Declining shoreline aesthetics
  • Degraded wetlands and wildlife habitats
  • Impaired recreational opportunities
  • Poor water quality
  • Reduced navigability
  • Restricted bathing beach access
  • Shellfish bed closures

Annual Stormwater Report & Public Input

The Town of Brookhaven is continuing to make great strides towards implementing its Stormwater Management Program and improving the stormwater infrastructure within the town. One of the requirements of the Town’s SPDES General Permit is the annual reporting of programs and accomplishments designed to address non-point source pollution. The Annual Stormwater Report, which has a reporting period ending March 9th annually, describes actions and activities undertaken by the Town to combat polluted stormwater runoff. The public has an opportunity to review and comment on the draft report every May, prior to filing the final report with NYSDEC. 

The draft 2022 Annual Stormwater Report is now available for review and comment. All prior year’s Annual Stormwater Reports are available for review.

What You Can Do

  • Don’t dump oil or other household chemicals down your household drains and street storm drains
  • Install permeable substrate, such as pavers or gravel, in your driveway and along walkways
  • Keep the storm drains in front of your house or business free of debris
  • Keep your car well maintained and leak-free
  • Landscape with plants native to our region thereby minimizing your need for fertilizers, pesticides and herbicides
  • Mulch leaves and lawn clippings
  • Pick up after your pet
  • Redirect your roof runoff into dry wells or rain gardens
  • Take advantage of your home refuse and create a compost pile for your garden

Get Involved

Looking for a community project for your group or event? For more information, contact the Town’s Stormwater Management Program Office.

Storm Drain Marking

Storm drains are not waste drains! Storm drain marking is an excellent way to educate your fellow neighbors on the connections between our neighborhoods and surface waters. The Town will provide your group with a map and a series of storm drain medallions to adhere to select drains in your neighborhood with a direct connection to surface water. This is an excellent community service project for scout groups or environmental clubs.

Pooch Bag Distribution

Pet waste is a significant contributor to water pollution. Encourage your neighborhood dog walkers to clean up after their pets by offering them tools to make the job easier. The Town will provide your group with a box of pooch bags and brochures for distribution at your community event or community center. This is an excellent community awareness project for civic groups or other community organizers.
