National Flood Insurance Program Information

FEMA's National Flood Insurance Program Information

In 1968, Congress created the National Flood Insurance Program (NFIP) to help provide a means for property owners to financially protect themselves. The NFIP offers flood insurance to homeowners, renters, and business owners if their community participates in the NFIP. Participating communities agree to adopt and enforce ordinances that meet or exceed FEMA requirements to reduce the risk of flooding.

Is Floodplain Insurance Being Required For Your Property?

  • Any requirement to hold floodplain insurance is done by the lending institution. 
  • A property may be able to use a Elevation Certificate (EC) to obtain a Letter Of Map Amendment (LOMA) to show the lender that FEMA believes that structure is reasonably safe from flooding. City staff can help with questions on this process, email staff at Here are some important notes about LOMA's:
    • LOMA's are not guaranteed to always be active on a property. 
    • Changes to the floodplain may cause LOMA's to not be renewed when new floodplain maps become effective (a process call revalidation). 
      • These changes could be due to a number of reasons but most often are a result of increasing Base Flood Elevations (BFE) that require new EC's to be completed and submitted to FEMA.
