Flood Information

Flooding in Treasure Island can be caused by heavy rainfall that occurs in short periods of time, as is common during summer thunderstorms, and by tidal surges that accompany tropical storms and hurricanes. Because of the City’s low land elevations and proximity to the Gulf of Mexico, the flood threat is significant. Hurricane tidal surges can cause flooding up to 24 hours before the eye of the storm reaches the coast. The potential for flood losses in Treasure Island always exists when tropical storms and hurricanes hit the area, as witnessed by Tropical Storm Eta in 2020. This page is designed to help you understand your flood zone for permitting purposes, flood insurance, preparing for a disaster, and more.

Flood Insurance
The City of Treasure Island participates in the National Flood Insurance Program (NFIP). The NFIP makes flood insurance policies available to property owners, renters, and businesses in order to help them recover faster after a flood event. 

Below are some key points regarding flood insurance:
  • To purchase flood insurance, call your insurance company or insurance agent, the same person who sells your home or auto insurance. If you need help finding a provider click here or call the NFIP at 877-336-2627.
  • Plan ahead as there is typically a 30-day waiting period for an NFIP policy to go into effect, unless the coverage is mandated it is purchased as required by a federally backed lender or is related to a community flood map change.
  • Most homeowners’ or renters’ insurance policies typically do not cover flood damage.
The City of Treasure Island is also enrolled in the NFIP’s Community Rating System (CRS) program. Treasure Island has a Class 6 Rating within the program, which provides property owners a 20% discount on flood insurance premiums. The current rating is achieved through mitigation efforts such as higher regulatory standards, outreach projects, and other initiatives.
