Shaded areas are FEMA’s mapped flood hazard zones in and around St. Lucie County, Florida. Zoomed out they are simplified; at street level the map switches to FEMA’s exact layer. Tap anywhere to check that spot, or search an address above.
St. Lucie County experiences a flood risk profile driven primarily by general floods and tropical systems, with 10 flood events and 8 tropical storm events recorded over the last 30 years. Recent impacts include major tropical systems, such as Hurricane Milton and Hurricane Helene in September and October 2024, which brought severe weather, tornadoes, and tropical storm conditions across the region.
National Flood Insurance Program records indicate that claims are heavily concentrated in designated special flood hazard areas. Zone A accounts for 2,933 claims with an average payout of $33,213 and an average recorded water depth of 7 inches. Zone V properties face the highest average severity, with 31 claims averaging $54,107 and an average recorded water depth of 14 inches. Meanwhile, Zone X properties recorded 878 claims averaging $27,395 with an average water depth of 7 inches, and Zone X shaded areas recorded 84 claims averaging $21,769 with an average water depth of 3 inches.
Homeowners and real estate professionals managing properties in Zone V and Zone A should pay the closest attention to flood risks, given the higher claim volumes, average payouts, and recorded water depths associated with these zones during tropical and severe weather events.

Tropical Storm · Sep 26, 2024. Major Hurricane Helene paralleled the west coast of Florida about 100 miles offshore before making landfall in the Big Bend region of Florida near the city of Perry. The system's expansive wind field within its eastern periphery produced a period of tropical storm conditions, particularly in gusts, across much of east central Florida including its adjacent coastal waters. Peak wind gusts ranged between 45 - 55 mph…
Flash Flood · Oct 9, 2024. Hurricane Milton moved ashore the west-central Florida coast as a category 3 hurricane on Oct 9 around 1930EST. The system continued slowly in an east-northeast trajectory across central Florida, becoming a category 1 hurricane before emerging into the Atlantic Ocean near Cape Canaveral. The outer rainbands of Milton overspread the Florida peninsula earlier in the day, leading to a prolific tornado outbreak across…

Storm Surge/Tide · Sep 29, 2022. After making landfall as a major hurricane in southwest Florida near Cayo Costa, Ian crossed the peninsula and into east central Florida (southern Osceola County) as a Category 1 Hurricane with estimated maximum sustained winds of 75 mph. The system was downgraded to a tropical storm shortly thereafter and emerged into the Atlantic Ocean near Cape Canaveral. Ian's slow movement and large wind field led to a long p…

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in St. Lucie County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.
Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
