Flood risk analysis along Florida's Atlantic coast.
From the Space Coast to Northeast Florida, this stretch of coastline sees a mix of oceanfront, intracoastal, and riverine flood exposure across its counties.
What shapes flood exposure in the East Coast region.
Florida's east coast is not one flood story but several. Oceanfront barrier islands from Jacksonville Beach to Hutchinson Island face wave action, dune erosion, and surge. Behind them, the Intracoastal Waterway and the Indian River, Banana River, and Halifax lagoons flood on wind-driven tides. And in Duval County, the St. Johns River can push water into neighborhoods miles from the ocean, as it did during Hurricane Irma in 2017.
Recent seasons have reshaped the coastline itself. Hurricanes Matthew, Irma, Ian, and Nicole each drove erosion and flooding in Volusia and Flagler, undermining oceanfront structures that were technically outside the highest-risk zones. A property-specific review looks at where a structure actually sits relative to the dune line, the lagoon, and the river — not only which zone it was mapped into.

Every review begins with a property address or parcel number. No site visit is required to start, and Groundswell sells no insurance, construction, or mitigation products.
Four things a zone letter won’t tell you about a East Coast property.
Oceanfront erosion and wave action
Barrier-island parcels in Volusia, Flagler, Brevard, St. Lucie, and Martin often carry VE zones. Dune condition and setback are as important as elevation in a nor'easter or hurricane.
Lagoon and Intracoastal tidal flooding
The Indian River Lagoon system and the Intracoastal Waterway flood on sustained onshore winds and king tides, affecting mainland and island shorelines alike.
St. Johns River riverine flooding
Jacksonville's riverfront neighborhoods — San Marco, Riverside, Ortega, and the Northside tributaries — face slow-rising riverine flooding that can arrive after a storm has passed.
Rainfall and drainage inland
Flat, sandy terrain across the region means heavy rainfall can flood inland subdivisions well outside any coastal zone, especially where drainage relies on ditches and retention ponds.
