FEMA Letter: Temporary Suspension of CLOMR-F & LOMR-F Applications
Developers who are interested in constructing within the SFHA (Floodplain) are encouraged to contact the permit center at 925-671-3425 to discuss City of Concord floodplain requirements, and available alternatives to the CLOMR-F/LOMR-F process.
Community rating system
The City of Concord participates in the voluntary program called Community Rating System (CRS) regulated under the Federal Emergency Management Agency (FEMA). The program rewards communities for following specific floodplain management activities by providing a discount on flood insurance.
The CRS uses a Class rating system that is similar to fire insurance rating to determine flood insurance premium reductions for residents. The Classes are rated from 10 to 1. The City is currently at a rating of 6 as of May 2020, which offers Concord policy holders a 20% discount on flood insurance premiums.
The main goals of the CRS are: 1) reduce flood damage to insurable properties 2) strengthen the insurance aspects of the National Flood Insurance Program (NFIP) and 3) foster comprehensive floodplain management.
