Although crawlspaces are not recommended in flood-prone areas, they can be designed or retrofitted to greatly increase resistance to flood damage.
Image
Flood vents allow floodwaters to enter and exit the crawlspace without causing hydrostatic pressure differences
Image
For seismic resistance in basement, crawlspace, and crawlspace “cripple” wall foundations, connect the plywood or OSB sheathing to the wall framing, rim joist, and sill plate and anchor bolt the sill plate to the foundation
Image
The goal of foundation moisture management is to construct the basement, crawlspace, or slab in a way that keeps moisture from getting in in the first place
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.
Image
This floor assembly above a vented crawlspace controls vapor and heat transmission by using foil-faced isocyanurate rigid foam insulation installed underneath the floor joists and fiberglass insulation in the floor joist cavities
