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.
Click on sections below to see information on flooding and keeping safe.
To protect yourself, learn what flood threats affect your neighborhood and your property.
- Is your property in a coastal high hazard or special flood hazard area
- Determine if there are rivers or creeks that flood frequently
- Is your home or business located in a low-lying area
- Determine your building's elevation
Due to the relatively flat terrain across Florida, it is complicated to drain accumulated water. When rivers rise, water tends to spread out far from riverbanks. During past flood events, rising rivers and repeated periods of heavy rainfall combined to pool water over land miles away from rivers. In fact, normally small rivers turned into vast lakes.
Pooling of water poses a significant risk, not as much from swift moving water, but because of the inability to judge water depth. Water only inches deep can be next to water that is several feet deep.
