Image
Right - In areas prone to costal flooding, elevate the bottom floor well above the design flood elevation.
Image
Right - Install backflow prevention devices on plumbing pipes to prevent wastewater from entering the home's plumbing system.
Image
Image
Right - Use flood-damage-resistant materials for decks and portions of the house below the design flood elevation.
Image
Right – Air vents near the top of the crawlspace wall are not used as flood vents, and flood vents are installed close to grade
Image
Image
Right – Interior grade is elevated and flood vents are located slightly above interior grade
Image
Right – Notch cut into pile takes less than 50% of cross section, cut is treated with wood preservative, and beam is installed with corrosion-resistant bolts.
Image
Right – The floor and wall system on this open-foundation home use rigid foam rather than fibrous cavity insulation to reduce risk of water damage.
Image
Right – The HVAC outdoor unit is anchored on a bed of masonry bricks, 1 foot or more above the base flood elevation.
Image
Right – The latticework between columns in this raised foundation will allow free flow of water in the event of a flood
Image
Right – The raised-slab, brick-and-block stem wall, above-grade walls, and roof of this house use flood damage-resistant materials, integrated water, vapor, and air control layers, and construction methods which promote good drainage and rapid drying
Image
Right – The raised-slab, CMU block stem wall, above-grade walls, and roof of this house use flood damage-resistant materials, integrated water, vapor, and air control layers, and construction methods which promote good drainage and rapid drying
Image
Right – The raised-slab, poured-concrete stem wall, above-grade walls, and roof of this house use flood damage-resistant materials, integrated water, vapor, and air control layers, and construction methods which promote good drainage and rapid drying
Image
Right – This column foundation has no HVAC equipment, piping, electrical components, or structural walls below the elevated floor system
Image
Right – This floor system on a column foundation is insulated using closed-cell spray foam rather than fibrous insulation
Image
Right – This HVAC condensing unit is elevated on a raised-slab
Image
Image
Right-Flood resistant foundation walls lift the floor framing above the DFE and include flood openings to let flood waters pass through.
Image
Rigid foam provides the code-required insulation values for this floor and wall assembly so that fibrous cavity insulation can be avoided, reducing risk of floodwater damage
Image
Image
Roof truss-to-masonry wall connectors embedded into concrete-filled or grouted masonry cell (left-hand side image has a top plate installed while the right-hand side does not).

Image
Section view of a deep pile foundation system constructed with reinforced concrete beams and columns to create portal frames, adapted from FEMA P-550, 2nd ed., case FEMA P-550, 2nd ed., case H.
Image
Section view of a steel pipe pile with concrete column and grade beam foundation type, adapted from FEMA P-550, case B.
Image
Shear wall hold-down connector with bracket attached to a wood beam for a home built on a pile foundation.
Image
Shingle blow-off often starts at the eaves, as shown here after exposure to 115-mph hurricane winds.
Image
SIP homes built in coastal locations should be constructed so that the lowest level is well above the BFE.
Image
Soil types include sand, silt, and clay- the more sand, the more quickly the soil drains.
Image
Stem wall foundation design, including additional reinforcement to resist moving floodwaters and short (1.5-ft) breaking waves (Source: Adapted from FEMA P-550, Case F).
Image
Storm-blown shingles reveal that the starter strip was incorrectly installed; rather than cutting off the tabs of the starter, the starter was rotated 180 degrees (right arrow) so the exposed portion of the first course of shingles (left arrow) was...
Image
The 3/8-inch gap under the door allowed wind-driven rain to enter the house in hurricane winds of 140 to 160 mph.
Image
Image
The brick house foundation piers on discrete footings (in the foreground) failed by rotating and overturning while the piers set in the concrete mat survived Hurricane Katrina.
Image
The components of a framed wall include from inside to out: gypsum, wood studs, OSB or plywood sheathing, and siding.
Image
Image
The elevated concrete floor over this concrete column foundation uses rigid foam on its interior surface to reduce thermal bridging and risk of floodwater damage
Image
Image
Image
The piles of this foundation were well embedded and survived floodwaters from Hurricane Katrina.
Image
The pilings for this building are showing signs of failure due to a poor siting decision to locate the home too close to the surf.
Image
The plywood panels on the underside of this house blew away in hurricane wind speeds of 105 to 115 mph due to corrosion of existing nails, excessive space between nails, and use of nails instead of screws.
Image
Image
The primary frontal dune will be lost to erosion during a 100-year flood because dune reservoir is less than 1,100 ft2
Image
The rails on these stairs were enclosed with siding, presenting a greater obstacle to the flow of flood water and contributing to the flood damage shown here.
Image
The right window frame was pulled out of the wall because of inadequate window frame attachment during a hurricane.
Image
The risk of hydrostatic pressure differences in a flood is reduced when the interior grade of the crawlspace is higher or equal to the exterior grade.
