Continuous load path failure due to improper connections between a home and its foundation allowed this building to be overturned in hurricane force winds.
Image
Continuous load path failure due to improper connections between the roof decking and roof framing resulting from hurricane force winds.
Image
Correctly anchoring an outside heating oil tank can prevent tank displacement if flooding occurs.
Image
Correctly anchoring an outside propane tank can prevent tank displacement if flooding occurs.
Image
Covering old asphalt shingles with new shingles can cause substrate irregularities that can interfere with the bonding of the self-seal adhesives in the new shingles.

Image
Diaphragm stiffening and corner pile bracing to reduce pile cap rotation for homes built on pile foundations.
Image
Distribution of roof, wall, and internal pressures on one-story, pile-supported building.
Image
Dry wells are underground tanks that store water to percolate or drain slowly to another site or sewer.

Image
Encourage dune formation by installing sand fences or pallets and planting dune grasses.
Image
Every natural gas appliance has a shutoff valve in the gas line to the appliance that can be manually shut off if a leak happens at a specific appliance or in preparation for an impending natural disaster.
Image
Image
Excess Flow Valves and Earthquake-Actuated Gas Shutoff Valves are two different types of valves that automatically stop the flow of gas into the house: excess flow valves stop gas flow if there is a break in the line, earthquake valves stop gas flow if th
Image
Expected flood damage (as a percent of building’s pre-damage market value) at flood depths above the bottom of the floor beam), for a building in the coastal V Zone and riverine A Zone.
Image
Exterior electrical service components are raised and clearances are provided around components to minimize contact with flood waters and people
Image
Extreme weather, such as wind, fire, flood, or extreme heat (included in the Severe Weather category above) causes most large electric disturbance events in the U.S (defined as affecting at least 50,000 customers) (data from 2000-2016)
Image
Failure at a gable end of a home under hurricane force wind conditions due to improper continuous load path design.
Image
Failure in brick veneer connection under high wind conditions due to anchor corrosion, tie fastener pull-out, failure to embed ties into the mortar, poor bonding between ties and mortar, and poor-quality mortar; on left - five ties not embedded.
Image
Failure of the wall to roof connection resulted in loss of roof under hurricane force winds.
Image

Image
Flood damage-resistant materials include concrete and tile flooring, metal cabinets and doors, and glass-block windows.
Image
Flood Insurance Premiums Can be Reduced Significantly by Building above the BFE.
Image
Flood vents allow floodwaters to enter and exit the crawlspace without causing hydrostatic pressure differences
Image
Image
For homes built in high probability flood zones, move all possible plumbing equipment above the Base Flood Elevation (BFE), shown here as “Flood Protection Level;” equipment that cannot be moved should be watertight to resist floodwater
Image
For homes built in V Zones a registered professional engineer or architect must certify that the lowest floor elevation is above the BFE and piles and structure are anchored to resist flotation, collapse, or lateral movement due to combined wind and water
Image
For homes built on an open foundation, provide a continuous air barrier by sealing all joints between the rigid insulation, floor support beams, rim joist, and bottom wall plate

Image
Fuel storage tanks are at risk of displacement during floods and should be securely anchored to the ground or base
Image
Fuel tank anchored below ground in a flood-prone area anchored to a counterweight to counteract the buoyancy force.
Image
Fuel tank is elevated above flood waters and anchored to supporting frame
Image
Fuel tank is elevated above flood waters on a base of structural fill and anchored to the concrete pad
Image
Gable-end bracing detail; nailing schedule, strap specification, brace spacing, and overhang limits should be adapted for the applicable basic wind speed.
Image
Glass blocks allow in daylight while maintaining privacy and also provide protection against high winds and floods.
Image
Image
Heavy-gauge metal strapping can be used to secure water heaters and other appliances

Image
If both the shingles and the underlayment blow off the roof is more susceptible to water intrusion; sealed seams or a self-adhering underlayment provide greater protection.
Image
If water rises above the foundation and enters the wall cavity it will not damage the moisture-resistant closed-cell foam or exterior extruded polystyrene, while gaps in the paperless drywall allow airflow of easy removal of panels for drying and cleaning
Image
Improperly installed fuel tanks can break free from attachments under the force of flood waters, risking broken fuel lines which could cause fire or explosion. Here, the tank is tethered only by the gas piping, which is not designed to perform this functi
Image
In Coastal A Zones and V Zones best practice is to construct the home so the bottom support of the lowest floor is above the 100-year wave crest elevation.
