As a public service, the County of Gem will provide you with the following information upon request:

  • Whether a property is in or out of the Flood Hazard Area (FHA) as shown on the current Flood Insurance Rate Map (FIRM) of the County.
  • Additional flood insurance data for a site, such as the FIRM zone and the base flood elevation or depth, if shown on the FIRM.
  • We have a handout on the flood insurance purchase requirement that can help people who need a mortgage or loan for a property in the SFHA.
  • The County of Gem maintains elevation certificates for review.
  • The County of Gem updates the Flood Insurance Rate Maps as needed when revisions are made to the maps.
  • 1978 Flood Insurance Study (.pdf)
