Florida Flood Map Changes and Your Project
Several Florida communities, including Port St. Lucie, Bradenton and Ormond Beach, have been working through FEMA flood map updates.
When a flood zone or base flood elevation changes, it can affect finished floor elevations, fill, stormwater design and what a site can support.
JRH Engineering is a Civil Engineer, Structural Engineer and Land Development firm serving Texas, North Carolina and Florida, with an office in Orlando.
JRH guiding principles are: Engineering Excellence. Delivered on Time. Built on Value.
What a Map Change Can Affect
Flood zone: a parcel can move into or out of a Special Flood Hazard Area
Base flood elevation: higher elevations can raise finished floors and fill
Stormwater: fill in the floodplain and new impervious area can change pond sizing
Foundations: elevated floors and wind loads shape the structural design
How to Stay Compliant
Check the current effective FEMA map before buying or designing.
Ask the local floodplain administrator about pending map revisions.
Get an elevation certificate from a licensed surveyor (by others) where required.
Coordinate grading, stormwater and foundation design to the same elevations.
Local Floodplain Offices
Port St. Lucie and St. Lucie County: St. Lucie County publishes flood protection information and flood zone lookups
Bradenton: floodplain management runs through the city’s Building and Permitting Division
Ormond Beach: see the city’s Floodplain Management page
Florida Rules to Know
FDEP or a water management district issues Environmental Resource Permits for stormwater systems
Updated stormwater rules apply to applications deemed complete after December 28, 2025
Construction sites disturbing 1 acre or more need FDEP construction stormwater coverage
