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
Image
The components of a framed wall include from inside to out: gypsum, wood studs, OSB or plywood sheathing, and siding.
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
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
This breakaway wall design made of decay resistant lumber is compliant with the National Flood Insurance Program.
Image
This concrete block foundation cracked due to lack of steel rebar reinforcement.
Image
This home constructed in a V Zone in Bolivar Peninsula, Texas, had the bottom beam of the lowest floor at the BFE (dashed line) but the estimated wave crest during Hurricane Ike was 3 to 4 feet higher (solid line).
Image
This home was elevated above the Design Flood Elevation and the pre-existing first story became the second story.
Image
This left-to-right sequence shows the method of wall extension to flood-proof a masonry house on a slab foundation. Here the new, raised floor is wood-framed over a wet-floodproofed crawlspace, but using fill to create a new raised slab is also an option.
Image
Image
This raised-slab CMU and brick foundation includes flood-resistant features such as a sloped grade, capillary break under the slab (gravel or sand), vapor barrier under the slab (polyethylene sheet), and capillary break at the top of the foundation wall
Image
This raised-slab poured concrete foundation includes flood-resistant features such as a sloped grade, capillary break under the slab (gravel or sand), vapor retarder under the slab (rigid insulation), and capillary break at the top of the foundation wall
Image
To control surface water, the land should slope away from the building on all sides
Image
Image
Wrong - In floodplains, the interior grade elevation should be equal to or higher than the exterior grade as shown on right.
Image
Wrong - The pile foundation of this home nearly collapsed from coastal storm surges because the piles were not embedded deeply enough in the ground.
Image
Image
Wrong – Piers set on individual footings with inadequate anchoring to the ground were twisted and toppled by a coastal storm surge, while those anchored in the concrete pad stayed upright.
Image
Wrong – The footers of this house were not deeper than the depth of scour during a flood, causing undermining of the foundation
Image
Wrong – The ridge flashing fasteners were placed too far apart and came loose in high winds.
Image
Wrong – This standard air vent has become blocked by flood debris and is located at the top of the foundation wall; it should not be used as a flood vent
Image
Wrong-The home was pulled off its masonry pier foundation during a coastal flood due to inadequate pier-to-beam connections.
Image
Wrong-These masonry pier foundations were twisted and displaced by coastal storm surges in Long Beach, Mississippi.
