  • Flood vents

    Outline

    Openings that let floodwater into an enclosure so hydrostatic pressure is relieved. Used in wet floodproofing below the required floor. A vent without the area the code requires is a hole, not a strategy.

  • Pile foundation

    Outline

    The house sits on piles, with the lowest floor above the flood requirement and the water free to pass underneath. Pile type, embedment, and the bracing are an engineer’s design, not a wall-system choice.

  • Elevated first floor

    Outline

    Living space raised above the design flood elevation, on piles, piers, or a stem wall with openings. What is allowed below that floor is as important as the height.

  • Slab on grade

    Outline

    A concrete slab cast at or near the ground. Simple on a dry, flat lot. A poor fit where the flood elevation is above the slab, and a termite path if the slab-to-wall joint is casual.

  • Grade beam

    Outline

    A reinforced concrete beam tying piles or piers together at or below grade. It is a foundation element, often paired with an elevated floor. It is not a wall system.

  • Wet floodproofing

    Outline

    Letting floodwater in and out of an enclosure below the living floor, with flood-damage-resistant materials and openings sized to the code. The strategy accepts water. It does not keep the lower level dry.

  • Dry floodproofing

    Outline

    Keeping water out of a structure with walls, seals, and often a way to resist hydrostatic load. Limited by code, by depth, and by how long the seal has to hold. Not a residential default.
