Waterfront exposure
Exposure D is the highest wind exposure category, applied to flat unobstructed areas exposed to wind over large bodies of water for at least 1 mile. Most waterfront properties in the Florida Keys fall into Exposure D, which increases design wind pressures by 15-25% compared to Exposure C.
Exposure D wind pressures are typically 15-25% higher than Exposure C for the same building height and wind speed. For example, a window requiring +60/-70 PSF in Exposure C might require +75/-85 PSF in Exposure D conditions.
Not all properties, but most waterfront locations in the Keys are classified as Exposure D. Properties with significant upwind obstructions or located more than 600 feet from the shoreline may qualify for Exposure C. A PE assessment determines the correct exposure category.
Waterfront windows in Monroe County require HVHZ-rated impact glazing with design pressures of +75 PSF or higher. Recommended products include heavy commercial-grade aluminum frames, marine-grade coatings (AAMA 2605), and enhanced laminated glass assemblies rated for Exposure D conditions.
