Floodplain Management

Communities that participate in the National Flood Insurance Program (NFIP) have agreed to adopt local floodplain regulations and enforce those regulations through a local permitting process. In return, flood insurance through the NFIP is made available for purchase to all residents and business owners in the community.

The Floodplain Administrator and the Building Official are responsible for implementing Hillsborough County’s floodplain regulations, ensuring that the County is in compliance with the National Flood Insurance Program’s (NFIP) minimum standards, and enforcing any additional, locally imposed standards.

Effective implementation of local floodplain management regulations is not only critical for residents’ safety, but it also helps minimize future flood damage.

  • Elevation and Floodproofing Certificates

    The Elevation Certificate is used to provide elevation information necessary to ensure compliance with community floodplain management ordinances. It is also used to determine the proper insurance premium rate and to support a request for flood map changes.

  • Request a Change to a Flood Map

    A Letter of Map Chane (LOMC) officially amends or revises an effective Flood Insurance Rate Map (FIRM) to remove a structure, lot, or portion of a property from the 1% annual chance floodplain. FEMA issues LOMC’s instead of physically revising the maps.

    FEMA’s Online LOMC tool allows homeowners or their designated representatives to request a Letter of Map Amendment (LOMA) or Letter of Map Revision (LOMR) to a flood map. It is a convenient way for applicants to upload the necessary documentation and check the status of their application online. Visit FEMA’s Online LOMC Application Portal to log in, create an Online LOMC account, or access user resources.

    FEMA’s eLOMA tool is specifically for licensed land surveyors and professional engineers to generate a quick determination from FEMA within minutes of submitting required information and data for the subject of the eLOMA request. Visit FEMA’s eLOMA Portal to log in, create an eLOMA user account, or access user resources.

     

  • Know Your Flood Hazard

    Flooding is the most costly and repetitive natural disaster affecting Hillsborough County. While residents are typically affected by inland flooding near lakes and in areas with low-lying elevations, flooding along rivers and coastal tidal surge are not uncommon. Flooding can occur anytime and anywhere when heavy or steady rain occurs. To find your flood zone, visit Hillsborough County’s Flood Information webpage. Learn how you can take action to protect your property, and more.
