Community Rating System Program

Pierce County participates in the Federal Emergency Management Agency (FEMA) Community Rating System (CRS) program. CRS is a voluntary incentive program that recognizes and encourages community floodplain management activities that exceed the minimum National Flood Insurance Program requirements. Pierce County’s participation in the CRS program requires an annual recertification of the activities that presently result in a 40% reduction in flood insurance policy premiums for properties in unincorporated Pierce County.


CRS Classes

The CRS uses a Class rating system that is similar to fire insurance rating to determine flood insurance premium reductions for residents. CRS Classes are rated from 9 to 1. Today, most communities enter the program at a CRS Class 9 or Class 8 rating, which entitles residents in Special Flood Hazard Areas (SFHAs) to a 5 percent discount on their flood insurance premiums for a Class 9 or a 10 percent discount for Class 8. As a community engages in additional mitigation activities, its residents become eligible for increased National Flood Insurance Program (NFIP) policy premium discounts. Each CRS Class improvement produces a 5 percent greater discount on flood insurance premiums for properties in the SFHA.  -FEMA Community Rating System Fact Sheet 2019
