Image
Anchorage failure in sliding glass doors due to negative pressures from hurricane force winds.
Image
Anchoring hardware is used to tie down equipment and components of the home to resist high winds and hurricanes.
Image
Image
Backup generators usually run on gas, propane, or diesel-powered and typical sizes for homes generate 2,500 to 7,500 watts.
Image
Image
Berms are compacted earth or gravel ridges that slow the flow of water from rain, riverine flooding, or storm surges in coastal areas.
Image
Berms, swales, bioswales, ridges, and vegetation all help to control rainwater runoff on residential sites.
Image
Bioswales or rain gardens filter storm water through vegetation and rock and sand substrate layers.

Image
Building elevation and plan view of roof showing longitudinal shear walls; dimensions are wall-to-wall and do not include the 2-ft roof overhang.
Image
Building siding extended down and over the breakaway wall so the upper wall was damaged when the lower wall broke away.
Image
Buildings damaged by a hurricane storm surge: upper homes on gulf shoreline were hit by large waves above the lowest floor, lower left home on bay and right school 1.3 miles from gulf shoreline were hit by surge and small waves.
Image
Built-up beam connections, knee brace connections, and diagonal brace connections for wood piles.
Image
Image
Casement windows or wing walls can create zones of higher pressure (right) and lower pressure (left) to encourage cross ventilation when wind is flowing parallel to window openings
Image
Child-proof slide locks can be used on drawers and cabinets to prevent their accidental, unintended use.
Image

Image
Coastal flooding washed away most of the first floor of this home; however, the piers and roof are still standing.
Image
Coastal flooding washed away this home but left the masonry piers, which are set in concrete bases.
Image
Image
Comfort ventilation focuses on airflow over occupants; in this example of wind-driven cross ventilation, the air is directed through the main occupied areas of the bedroom
