FLORIDA · PALM BEACH COUNTY JURISDICTION
Where the Atlantic meets Flagler Drive, the wind sets the structural rules
West Palm Beach faces open ocean across the Intracoastal Waterway, so design winds run among Florida's highest — without the statutory HVHZ label that belongs only to Miami-Dade and Broward.
A COMMON MISLABEL · CORRECTED
High winds, but not a High-Velocity Hurricane Zone
The statutory HVHZ covers only Miami-Dade and Broward. Palm Beach County sits just north of that line — serious coastal winds, ordinary FBC enforcement.
West Palm Beach designs to the same elevated 3-second-gust speeds as its HVHZ neighbors, yet products clear through standard Florida Product Approval rather than a county NOA program. Treat it as a high-wind, wind-borne-debris county — not as HVHZ.
ATLANTIC EXPOSURE · BARRIER-ISLAND FETCH
Reading exposure from the oceanfront inland
Distance from open water drives the exposure call between Flagler Drive and the western suburbs near Wellington and Royal Palm Beach.
Exposure D — oceanfront
Lots fronting the Atlantic and the Intracoastal Waterway, where unobstructed water fetch demands the most severe pressures.
SHORELINE SITESExposure C — the default
Open coastal terrain with scattered obstructions; the conservative baseline across most West Palm Beach parcels.
MOST PROJECTSExposure B — sheltered inland
Western neighborhoods with dense, durable obstructions — allowable only with engineering justification the official accepts.

What a sealed West Palm Beach submittal has to show
Six items separate an approvable wind package from a rejected one along this stretch of coast.
Site-specific design speed
Pull V from the ASCE 7-22 map for the exact address — roughly 165–175 mph Risk II, never a single assumed figure.
VARIES BY SITEExposure determination
Document C, D, or justified B against the actual surrounding terrain expected over the building's life.
C / D / BRisk-category mapping
Per Table 1.5-1, higher categories read a longer return-period map — III and IV pull a higher V than Risk II.
TABLE 1.5-1Wind-borne-debris glazing
All of Palm Beach County is a debris region: impact-rated openings or approved shutters on every exterior glazed assembly.
IMPACT OR SHUTTERSFlorida Product Approval
Roofing, cladding, doors and windows carry a state approval (or accepted Miami-Dade NOA) — no county NOA exists here.
