OPENINGS*

* A floor that is below ground level (grade) on all sides is considered a basement even if the floor is used for living purposes, or as an office,

garage, workshop, etc.

** An “opening” is a permanent opening that allows for the free passage of water automatically in both directions without human intervention.

Under the NFIP, a minimum of 2 openings is required for enclosures or crawlspaces. The openings shall provide a total net area of not less

than 1 square inch for every square foot of area enclosed, excluding any bars, louvers, or other covers of the opening. Alternatively, an

Individual Engineered Flood Openings Certification or an Evaluation Report issued by the International Code Council Evaluation Service (ICC

ES) must be submitted to document that the design of the openings will allow for the automatic equalization of hydrostatic flood forces on

exterior walls. A window, a door, or a garage door is not considered an opening; openings may be installed in doors. Openings shall be on at

least 2 sides of the enclosed area. If a building has more than 1 enclosed area, each area must have openings to allow floodwater to directly

enter. The bottom of the openings must be no higher than 1.0 foot above the higher of the exterior or interior grade or floor immediately below

the opening. For more guidance on openings, see NFIP Technical Bulletin 1.
