Map Maintenance

  • The National Flood Insurance Program (NFIP) is administered at the local community level. Support is available through the State NFIP Coordinator and your Regional (FEMA) Compliance Specialist.
  • As development occurs within the community, local officials should update the effective information for their community through the Letter of Map Revision (LOMR) process.
      • A community may request a hydrologic and hydraulic study be performed by developers interested in community investment, allowing the community to understand the change to flood risk within the community.
      • In areas with Zone A and Zone AE designation, increases of 1 foot or larger require the submittal of a Conditional Letter of Map Revision (CLOMR) as well.
      • For streams that also have a designated Floodway, any increase in the water surface requires the submittal of a Conditional Letter of Map Revision (CLOMR) as well
      • No Rise Certifications should be documented by a certification statement and a hydrologic and hydraulic study. The community is responsible for the review and collection of these study results.
  • Communities can apply to the Community Rating System (CRS) to be rewarded for the flood protection activities that are undertaken within their community to reduce flood risk.
      • The community is rewarded with a reduction in flood insurance premium rates for their residents and business owners based on the community’s CRS classification.
  • If a community is interested in additional steps it may take to lower flood risk within their community, FEMA’s CRS Coordination Manual includes activities that are focused to increase risk awareness and implement mitigation actions within their community.
      • Some actions identified within the manual include public outreach, land development criteria, open space or freeboard requirements, etc…
