Flooding is the most costly and repetitive natural disaster affecting Hillsborough County. Significant rainfall events or tropical storm surge can result in repeat flooding within some areas of the county. Flood maps, also known as Flood Insurance Rate Maps, are a useful tool for assessing a property’s flood risk, and also are a factor in flood insurance and building requirements. As new data and technology become available, maps are updated to show areas where the risk of flooding has changed.

For advice on ways to protect your property from flooding, contact Public Works’ Hazard Mitigation Program at (813) 307-4541. You also may request a staff member visit your property for further information on retrofitting, remodeling, and other topics.
