A drywell, shown here used for downspout catchment, can also be used to receive water from a French drain.
Image
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
Comprehensive water management features include a capillary break (≥ 6-mil polyethylene sheeting) at all crawlspace floors
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
Connecting hardware helps tie the walls to the top plates and rim joists to ensure a continuous load path to improve a building’s resistance to high winds, floods, and earthquakes.
Image
Image
Correct seismic retrofit hardware for securing the sill plate to foundation wall
Image
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
Image
Image
Good water management practices like sloping grade away from house, and installing gutters, perimeter drain pipe, a capillary break, and free-draining soils or drainage mat protect the foundation from water saturation.
Image
Image
Hurricane straps, hold-down connectors, and bolts help to transfer loads from the building’s walls to its foundation, increasing resistance to vertical and horizontal pressures acting on the building from wind, waves, or ground movement.
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
Key connection points for a continuous load path for earthquake and high wind disaster resistance
Image
Image
Lower-story wall anchorage to masonry (or concrete) base. Straps properly nailed at wall studs.
Image
Image
New Charleston, SC home's first level used as parking, storage, and access space
Image
Image
Image
Image
Properly reinforce masonry walls in coastal locations to resist high winds and waves.
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 - A continuous load path connects the roof and wall framing to the foundation.
Image
Right - Flood resistant slab and crawlspace foundations elevate the floor above the design flood elevation.
Image
Image
Right – Examples of wall stud to sill plate and foundation and wall rod connectors and brackets.
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 drain slopes away from the foundation and terminates at the proper distance
Image
Image
Image
Right-Flood resistant foundation walls lift the floor framing above the DFE and include flood openings to let flood waters pass through.
