National Flood Insurance Program Community Rating System

The Community Rating System (CRS) is a voluntary incentive program that recognizes and encourages community floodplain management practices that exceed the minimum requirements of the National Flood Insurance Program (NFIP). Over 1,500 communities participate nationwide.

In CRS communities, flood insurance premium rates are discounted to reflect the reduced flood risk resulting from the community’s efforts that address the three goals of the program:

  1. Reduce and avoid flood damage to insurable property
  2. Strengthen and support the insurance aspects of the National Flood Insurance Program
  3. Foster comprehensive floodplain management

Community Rating System Coordinator’s Manual

The Coordinator’s Manual is the guidebook for the Community Rating System. The Coordinator’s Manual explains how the program operates, how credits are calculated, what documentation is required, and how class ratings are determined. It also acts as guidance for communities in enhancing their flood loss reduction and resource protection activities.

In January 2021, an addendum to the Coordinator’s Manual became effective. The 2021 Addendum and the 2017 CRS Coordinator’s Manual together will constitute the official statement of CRS credits and procedures. These two documents will remain effective until a fully revised edition of the Coordinator’s Manual is issued in the future.

CRS Fact Sheets

The CRS program provides CRS Fact Sheets to highlight information that is relevant over many years or may be relevant to a current or specific topic.  Examples of the current or specific topic Fact Sheets may be applicable to the recovery phase of a particular disaster or the beginning of a new CRS program initiative. In 2021 several CRS Fact Sheets are planned for production. They will be posted as they become available.

Community Rating System

How are Flood Insurance Premium Discounts for CRS Communities Calculated?

Flood insurance premium rates in Community Rating System communities are discounted in increments of 5%. A Class 10 community is not participating in the CRS and receives no discount. A Class 9 community receives a 5% discount for all policies in its Special Flood Hazard Areas, a Class 8 community receives a 10% discount, all the way to a Class 1 community, which receives a 45% premium discount. 

Classifications are based on 19 creditable activities, organized in four categories:

  • Public Information
  • Mapping and Regulations
  • Flood Damage Reduction
  • Warning and Response

The table below shows the credit points earned, classification awarded and premium reductions.

*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 Community Rating System because it already has a lower premium than other policies. The Community Rating System credit for AR and A99 Zones are based on non-Special Flood Hazard Areas (non-SFHAs) (B, C and X Zones).

Credits include: Classes 1 – 6 at 10%. Classes 7 – 9 at 5%. Premium reductions are subject to change.
