This swale and berm slow the flow of stormwater across a site to minimize erosion.
This synthetic stucco (EIFS) siding which was installed over EPS that was adhered to gypsum board failed in high winds when the gypsum board pulled over the fasteners that mechanically attached it to the studs.
This windows in this very old building in the Virgin Islands are protected from hurricanes with robust shutters constructed of 2x4 lumber, bolted connections, and heavy metal hinges.
To avoid leakage if the hip or ridge shingles blow off, the underlayment should be lapped over the hip and ridge, unless there is a ridge vent.
Variation of maximum negative main wind force resisting system (MWFRS) pressures based on envelope procedures for low-rise buildings.
Vertical (buoyant) flood force; buoyancy forces are drastically reduced for open foundations (piles or piers).
Water depth versus wave height, and water depth versus breaking wave force against, a vertical wall.
Wave scour at a single vertical foundation member (pile), with and without underlying scour-resistant stratum.
When averaged over several years, more fatalities are caused by extreme heat than by any other weather-related hazard
When flood waters reach living areas, the resulting mold and contamination can greatly increase clean up time and costs.
When the EIFS siding on this house gave way in high winds, it revealed severe rotting of the sheathing beneath the windows due to long-term water leakage.
When the lower break-away wall gave way in coastal flooding it peeled some of the EIFS siding off with it because there was no suitable break in the siding to allow it to detach cleanly.
When the soffits blew away in 140 to 160 mph hurricane winds, wind-driven rain was allowed to enter the attic.
Wrong - In floodplains, the interior grade elevation should be equal to or higher than the exterior grade as shown on right.
Wrong - Leaks in the roof sheathing can allow water to get in and wet the drywall, providing fertile ground for mold.
Wrong - Mold can spread rapidly in flood damaged homes if materials aren't dried quickly.
Wrong - The pile foundation of this home nearly collapsed from coastal storm surges because the piles were not embedded deeply enough in the ground.
Wrong – Piers set on individual footings with inadequate anchoring to the ground were twisted and toppled by a coastal storm surge, while those anchored in the concrete pad stayed upright.
Wrong – The ridge flashing fasteners were placed too far apart and came loose in high winds.
Wrong-The home was pulled off its masonry pier foundation during a coastal flood due to inadequate pier-to-beam connections.
Wrong-These masonry pier foundations were twisted and displaced by coastal storm surges in Long Beach, Mississippi.
