CoreLogic has released data analysis sharing that 1,044,412 single-family and multifamily homes along the Florida Gulf Coast are at potential risk of storm surge damage from Hurricane Ian based on a National Hurricane Center forecast Sept. 26. Assuming Hurricane Ian makes landfall as a Category 4 hurricane, the reconstruction cost value (RCV) of those 1,044,412 homes sits at approximately $258.3 billion, according to CoreLogic.

“Hurricane Ian has all the ingredients you need for a bad storm surge event. Due to Hurricane Ian’s slower speed and rapid intensification in the eastern Gulf of Mexico, the threat of a widening wind field bringing damaging storm surge increases each day,” says Dr. Tom Jeffery, senior hazard scientist, CoreLogic.

“Many homes along Florida’s western coast are at risk of storm surge inundation regardless of where the storm makes landfall, and even more homeowners will contend with heavy rainfall and hurricane-force winds throughout mid-week.”

CoreLogic’s chart breaks down the residential single-family and multifamily homes at risk of storm surge damage. Single-family residential structures less than four stories, including mobile homes, duplexes, manufactured homes, and cabins, are included.

Given the current path of the storm, the data shows the total numbers of homes with potential exposure. RCV figures include the cost to completely rebuild homes with current localized costs of building materials and labor. The figures assume complete destruction of at-risk homes and not a representation of expected damages.
