National Flood Insurance Program Community Rating System

This page provides fact sheets, contact information, a national map of participating communities, details about how community discounts are calculated, and other information about the Community Rating System.

The National Flood Insurance Program's (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 damage to insurable property;
  2. Strengthen and support the insurance aspects of the NFIP, and
  3. Encourage a comprehensive approach to floodplain management.

How are Flood Insurance Premium Discounts Calculated?

For CRS participating communities, flood insurance premium rates are discounted in increments of 5 percent (i.e., a Class 1 community would receive a 45 percent premium discount, while a Class 9 community would receive a 5 percent 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:

  1. Public Information;
  2. Mapping and Regulations;
  3. Flood Damage Reduction; and
  4. Flood Preparedness.

The table below shows the credit points earned, classification awarded and premium reductions given for communities in the NFIP CRS.

*Special Flood Hazard Area
**Preferred Risk Policies are available only in B, C and X Zones for properties that are shown to have a minimal risk of flood damage. The Preferred Risk Policy does not receive premium rate credits under the CRS because it already has a lower premium than other policies. The CRS credit for AR and A99 Zones are based on non-Special Flood Hazard Areas (non-SFHAs) (B, C and X Zones). Credits are: classes 1-6, 10 percent and classes 7-9, 5 percent. Premium reductions are subject to change.

CRS Coordinator's Manual 
The Coordinator’s Manual for the CRS includes the CRS Schedule, which sets the criteria for CRS classification and CRS Commentary on the schedule.

  • Section 100 gives general background information on the CRS.
  • Section 200 explains the application and verification procedures.
  • Sections 300 through 700 explain the credit points and calculations that will be used to verify CRS credit.

The procedures in these sections are used by a community to submit a modification for a better CRS classification.
