Coastal & Flood Zone Design

Florida has more properties in FEMA Special Flood Hazard Areas (SFHAs) than any other state. AE zones, VE zones, and the newer coastal A zones each carry different construction requirements — and the difference between getting it right and getting it wrong can mean the difference between a structure that survives a hurricane and one that doesn't. We design for the specific flood zone your property is in. That means calculating the correct Base Flood Elevation, determining the required freeboard, designing the foundation system to meet FEMA requirements, and producing the documentation your building department and flood insurance carrier need.

Miami-Dade and Broward Counties are designated as the High Velocity Hurricane Zone — the most stringent wind design jurisdiction in the United States. HVHZ requires products with Miami-Dade Notice of Acceptance (NOA), specific structural connection requirements, and a more rigorous plan review process. Our engineers are experienced with HVHZ requirements and produce drawings that satisfy Miami-Dade and Broward building departments. We specify NOA-compliant products, design connections to HVHZ standards, and navigate the HVHZ plan review process efficiently.

Elevated construction on pile foundations is standard practice throughout coastal Florida. Whether your project is in a VE zone requiring open foundation construction, an AE zone where elevation above BFE is required, or a coastal area where soil conditions demand deep foundations, we design the foundation system your project needs. We work with concrete piling, timber piling, and helical piers — selecting the appropriate system based on soil conditions, flood zone requirements, structural loads, and local contractor availability.

Florida's Coastal Construction Control Line (CCCL) and local coastal setback regulations add another layer of complexity to coastal projects. Construction seaward of the CCCL requires a Florida DEP permit in addition to the local building permit. Setback variances, CCCL permits, and coordination with DEP are part of the coastal engineering process. We help clients understand the regulatory framework for their specific property and navigate the permitting process efficiently.
