Flood Awareness Information

-A A +A

About one-third of the parcels of land located in Stonington are within a Special Flood Hazard Area (i.e., “flood zone”). As a coastal community, the Town of Stonington’s goal is to raise awareness regarding the risks associated with flooding, provide technical assistance to mitigate these risks, and create a flood resilient community. Some of the ongoing initiatives include:

  • Coastal Resilience Study

It is important to understand what community infrastructure is vulnerable to sea level rise, coastal storm surge and severe storm events. This study provides valuable information which can be utilized by the community when making decisions regarding future development and public investment. Details about the Study can be found here: (http://www.stonington-ct.gov/planning-department/pages/stonington-ct-resiliency-plan). 

  • Community Rating System

The Town has recently been accepted into the FEMA Community Rating System (CRS) program as a level 8 community. As many properties in the Special Flood Hazard Area have flood insurance, one of the benefits of the CRS Program is that it provides eligible properties with a reduction in the flood insurance premiums. In addition to the most recognized incentive of the CRS program, implementation of a robust CRS program builds a more resilient community. Details about the CRS Program can be found here: (https://www.fema.gov/community-rating-system).         

  • Flood Awareness Newsletter

Annually, the Town issues a newsletter, which is mailed to all residents with structures in a Special Flood Hazard Area. This outreach strategy targets properties that have the highest risk from flooding and provides owners with useful information regarding: flood insurance, financial resources, flood mitigation measures, and various safety tips.  To view a copy of the latest newsletter, click here.

  • Technical Assistance

Town officials work to provide assistance with flood-related questions & general information provided to: residents, developers, contractors, insurance agents, realtors and businesses within flood hazard areas. We also provide technical assistance for map changes and flood zone determinations.
