Community Rating System & National Flood Insurance Program

National Flood Insurance Program & CRS

The National Flood Insurance Program (NFIP) Community Rating System (CRS) is a voluntary incentive program that recognizes and encourages community floodplain management activities that exceed the minimum NFIP requirements. As a result, flood insurance premium rates are discounted to reflect the reduced flood risk resulting from the community actions meeting the three goals of the CRS: (1) reduce flood losses; (2) facilitate accurate insurance rating; and (3) promote the awareness of flood insurance.NFIP/CRS Important Links for Residents and Businesses

National Flood Insurance Program

Community Raying System

In 2014, the Village of Mamaroneck has received a formal determination from FEMA on our application to become a member of the Community Rating System Program. Our official rating is an "8", which means that many residents will receive up to a 10% reduction on all flood insurance premiums that became effective after October 1, 2014.

For CRS participating communities, flood insurance premium rates are discounted in increments of 5%; i.e., a Class 1 community would receive a 45% premium discount, while a Class 9 community would receive a 5% discount (a Class 10 is not participating in the CRS and receives no discount). The CRS classes for local communities are based on 18 creditable activities, organized under four categories:

  • Public Information (Series 300) This series credits programs that advise people about the flood hazard, flood insurance, and ways to reduce flood damage. These activities also provide data needed by insurance agents for accurate flood insurance rating. They generally serve all members of the community and work toward all three goals of the CRS.
  • Mapping and Regulations (Series 400) This series credits programs that provide increased protection to new development. These activities include mapping areas not shown on the FIRM, preserving open space, enforcing higher regulatory standards, and managing storm water. The credit is increased for growing communities.
  • Flood Damage Reduction (Series 500) This series credits programs for areas in which existing development is at risk. Credit is provided for a comprehensive floodplain management plan, relocating or retrofitting floodprone structures, and maintaining drainage systems. These activities work toward the first goal of the CRS, damage reduction.
  • Flood Preparedness (Series 600) This series credits flood warning, levee safety, and dam safety programs. These activities work toward the first and third goals of the CRS, damage reduction and hazard awareness
