Overview of the Town of Groton Stormwater Management Plan

The Town of Groton along with other communities in the state, are required to address the impacts of stormwater runoff by developing and implementing a Stormwater Management Plan (SWMP).  The City of Groton has developed its own individual SWMP that can be viewed at  The Groton Long Point Association has also developed and maintains its own individual SWMP.

The Town’s SWMP meets the requirements of the Connecticut Department of Energy & Environmental Protection’s (CT DEEP) General Permit addressing stormwater management.  The CT DEEP developed this general permit for the State of Connecticut to comply with the federal Environmental Protection Agency’s (EPA) stormwater regulations. 

In 1987, the EPA amended the Clean Water Act to require a two-phased national program to address water pollution from stormwater runoff.  Phase I addressed stormwater runoff in approximately 900 of the nation’s largest cities.  Phase II regulations require communities located in urbanized areas with populations of fewer than 100,000 people to obtain a permit for their stormwater runoff.  In Connecticut, permits are issued by the CT DEEP.  

As originally determined by the 2000 census and confirmed by the 2010 census, much of the Town of Groton is in an urbanized area and therefore, the Town is required to register for and comply with the CT DEEP General Permit. 

The primary goal for Stormwater runoff and the SWMP is to improve the quality of the nation’s waterways for drinking and recreational purposes in accordance with the Clean Water Act.

The SWMP is a long-term initiative with the goal of improving the overall quality of the Town of Groton’s stormwater runoff.  The Town designed its own SWMP to develop and implement best management practices (BMPs) for the following six minimum control measures:

  1. Public Education and Outreach
  2. Public Involvement / Participation
  3. Illicit Discharge Detection and Elimination
  4. Construction Site Stormwater Runoff Control
  5. Post-construction Stormwater Management in New Development and Redevelopment
  6. Pollution Prevention / Good Housekeeping for Municipal Operations

A complete copy of the Stormwater Management Plan is available for review at the Town of Groton Department of Public Works located in the Town Hall Annex.
