A seismic snubber is a type of bracket specifically designed to anchor heavy equipment to the floor to restrain it in the event of an earthquake.
Image
A water heater and furnace are protected from flood waters by a concrete floodwall, with a shielded, gasketed door.
Image
All electrical system components should be raised above the design flood elevation to protect against water and speed up recovery, unless properly designed to be water-tight per code requirements.
Image
Although crawlspaces are not recommended in flood-prone areas, they can be designed or retrofitted to greatly increase resistance to flood damage.
Image
An alternative design includes strapping the tank to concrete counterweights on opposite sides of the tank.
Image
An engineered bioswale uses perforated pipe laid in rock and landscape fabric at the bottom of a vegetated trench to direct water away from a site.

Image
An underground fuel tank is anchored onto poured-in-place concrete counterweights.
Image
Anchoring a fuel tank to a concrete slab is recommended to avoid displacement if flooding occurs.
Image
Backflow prevention devices keep water and sewage from entering the home during a flood preventing damage and health and safety issues.

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 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.
