Central Florida homeowners got a wake-up call this week after a News 6 investigation found nearly 350,000 properties across Florida face flood hazards that FEMA’s official maps do not mark as high risk. The News 6 list names neighborhoods very familiar to Orlando-area residents, including Pine Hills, Poinciana, and Union Park, places many locals have long assumed sit safely outside the worst flood zones. That gap is not just a technicality, since FEMA flood-zone designations often determine who must carry flood insurance and which communities qualify for federal mitigation dollars.
A News 6 probe reached that number after comparing public flood layers with private risk models, according to ClickOrlando. The station reports that its statewide count includes neighborhoods that FEMA’s Flood Insurance Rate Maps do not currently list as Special Flood Hazard Areas. Several residents and real-estate contacts told the station they were caught off guard when insurers or agents flagged flood exposure in neighborhoods they had long considered low risk.
How FEMA Maps Work and Where They Fall Short
FEMA’s Flood Insurance Rate Maps are the federal baseline for mortgage and insurance decisions, but they are produced through a rolling update process and do not capture every type of flooding or every local condition. The agency’s Flood Map Service Center notes that maps may be superseded as new studies and data arrive, which means an address shown as low risk on an older FIRM can still face real flood hazards today. Local factors such as clogged drainage, filled lots, pond overflows, or a high water table can all create exposure that FEMA maps do not always reflect.
Private Models and National Analyses Show Broader Risk
Independent tools that model heavy rainfall, groundwater, and sea-level rise often flag properties FEMA’s FIRMs do not. First Street Foundation’s Flood Factor and peer analyses have found that FEMA maps can undercount at-risk addresses, an issue outlined in Scientific American and discussed on First Street’s site. Industry analysts warn the protection gap is serious: a recent Moody’s review identified hundreds of billions in potential uninsured flood losses where regulatory maps understate exposure, which helps explain why thousands of Florida properties might be “unrecognized” on FEMA maps.
What Orlando-Area Homeowners Should Do Now
Homeowners are being urged to start by looking up their addresses on FEMA’s Flood Map Service Center and on independent tools such as Flood Factor, then comparing the results. If you believe your property is mis-mapped, FEMA offers a process to request a Letter of Map Amendment or file an online map change (eLOMA/LOMC); FEMA’s mapping portal explains those options and how to apply. It can also be worth securing an elevation certificate and getting written flood-insurance quotes. County guidance notes that roughly a quarter of flood claims come from properties outside high-risk zones, so being outside a FIRM’s Special Flood Hazard Area is not the same as being safe…
