Community Rating System

The Community Rating System (CRS) is an incentive program that encourages communities to adopt floodplain management activities exceeding the minimum National Flood Insurance Program (NFIP) requirements. CRS goals are to:

  • Reduce flood losses.
  • Facilitate accurate insurance ratings.
  • Promote the awareness of flood insurance.

In return for a community’s adoption of standards that go above and beyond the minimum NFIP requirements, flood insurance premium rates for residents within the participating community are discounted. The discounts are designed to reflect the reduced flood risk to property owners resulting from the community’s floodplain management activities, and the amount of the discount varies according to the community’s level of effort.

Valley County’s rating is a 7.
