Hillsborough County is part of a multi-year process led by the Federal Emergency Management Agency (FEMA) to update coastal flood maps. The coastal flood risks shown on today's flood maps are based on obsolete data and technology more than 30 years old. The 2007 countywide flood map update did not include an updated analysis of the coastal flood risk and does not reflect new development or changes in shoreline.
Revised Maps Better Reflect Risks
This map revision more accurately reflects today's flood risks, which will:
- Provide property owners along the coast of Hillsborough County with up-to-date, reliable, Internet-accessible information about their risk of storm surge-driven coastal flooding
- Help residents and business owners make more informed decisions about protecting their property and financial stability
- Allow community planners, local officials, engineers, builders, and others to make important determinations about where and how new structures and developments should be built
Preliminary Map Revisions for Coastal Areas
Flood Map Assistance - Community Office Hours
To provide residents and business owners in the update area additional opportunities to view the preliminary maps, the County is hosting a series of community office hours:
- Saturday, April 27, 10:30 AM to 5 PM, Town 'N Country Regional Library, 7606 Paula Drive in Tampa
- Wednesday, May 1, 9 AM to 4 PM, SouthShore Regional Service Center, 410 30th St. SE in Ruskin
- Saturday, May 4, 10:30 AM to 5 PM, SouthShore Regional Library, 15816 Beth Shields Way in Ruskin
Hillsborough County Hazard Mitigation staff and flood specialists will be on hand to discuss one-on-one how the changes impact individual property owners.
What to Expect
- Expect changes to loan requirements and flood insurance costs in areas where updates occur. Some residents and business owners will find that their flood risk has increased, while others it may actually have been reduced. The NFIP has insurance cost-saving rating options to help reduce financial impacts.
- Revised flood maps will guide Hillsborough County's planning decisions and development requirements resulting in a more resilient county.
- New FIRMs become effective in 2020, though the County will keep the public and stakeholders informed throughout process.

More about FIRMs
A Flood Insurance Rate Map (FIRM) is an official map on which the Federal Emergency Management Agency (FEMA) identifies areas of high, moderate and low flood risk. Since the late 2000s, FEMA has been updating Flood Insurance Studies and Flood Insurance Rate Maps for the entire populated coastline of the country to provide improved flood risk information to coastal communities along the Atlantic and Pacific Oceans, the Gulf of Mexico, and the Great Lakes.
Important Note: Flooding occurs not only in high-risk areas, known as Special Flood Hazard Areas, but also in areas with a low to moderate risk on a FIRM. Anyone can be financially vulnerable to floods. People outside of high-risk areas file over 20 percent of National Flood Insurance Program claims and receive one third of FEMA's disaster assistance for flooding.
