Floodplain Management

Managing activities within areas susceptible to flooding assists with:

  • Protecting against loss of property and human life
  • Preserving natural resources and habitats
  • Planning for long-range stormwater management and water quality
  • Becoming a resilient community following storm events

 

As a participant in the National Flood Insurance Program (NFIP), the City of Groton is required to regulate development within certain flood prone areas. These requirements are found in Section 5.3 Flood Protection Overlay Zone, of the City of Groton Zoning Regulations. Section 5.3 outlines the requirements of a Flood Development Permit which is necessary for certain improvements within a Special Flood Hazard Area (SFHA). SFHAs are locations that have a 1% chance of flooding in any given year, sometimes referred to as the “100-year flood”. It is important to note that this 100-year “description” does not imply such a flood will only occur once per 100-years.  SFHAs are depicted upon Flood Insurance Rate Maps (FIRMs).

Certain SFHAs are locations within the City designated as Coastal High Hazard Areas. In general terms, the Coastal High Hazard Area occurs along an open coast and areas subject to “high velocity waters caused by, but not limited to, hurricane wave wash.” These areas have great potential to cause damage to property and loss of life.

City of Groton FIRMs are provided for download at the bottom of this page. Additional technical information supporting the FIRM panels is provided within the Flood Insurance Study (FIS).
