A raised wood pier foundation can raise the subfloor above the design flood elevation.
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
Closed-cell spray foam insulates the floor above a vented crawlspace; a protection board made of fiber cement is screwed in place under the floor joists to keep out pests

Image
Concrete pier foundations can be used in place of wood piles in coastal areas where risk of erosion and scour is low.
Image
Connecting hardware helps tie the roof to the walls to ensure a continuous load path to improve a building’s resistance to high winds, floods, and earthquakes.

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
Image
Image
Fuel tank is elevated above flood waters on a base of structural fill and anchored to the concrete pad
Image
Green Coast Enterprises built this New Orleans home on piers so that the floor is 1 foot above the base flood level; borate treated framing and closed-cell spray foam insulation add to the home's moisture resistance.
Image
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.
Image
In high wind areas, provide lateral support to masonry end walls to resist high winds.
Image
In high-wind regions, special hardware is used for most framing connections; toe-nailing is not acceptable.

Image
New Charleston, SC home's first level used as parking, storage, and access space
Image
Image
Properly reinforce masonry walls in coastal locations to resist high winds and waves.
Image
Provide a continuous air barrier from the rigid foam below the crawlspace floor joists to the rim joist to the exterior wall above
Image
Raised-slab CMU foundation including flood-resistant features: sloped grade, damp proofed stem wall, capillary break under the slab (gravel or sand), vapor barrier under the slab and capillary break at the top of the foundation wall (polyethylene sheet)
Image
Recommended construction for homes in Zone B (areas of moderate flood hazard between the 100-yr and 500-yr flood) and Zones C and X (areas of minimal flood hazard above the 500-yr flood).
Image
Recommended installation techniques for electrical and plumbing lines and other utility components in homes built on piers above the base flood elevation.
Image
Image
Repair leaks and cracks, and cover holes in foundation floors and walls to minimize water and vapor entry.
Image
Right - Flood resistant slab and crawlspace foundations elevate the floor above 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 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
Image
Right-Flood resistant foundation walls lift the floor framing above the DFE and include flood openings to let flood waters pass through.
