Overview
The national flood insurance program (NFIP) has a primary goal of protecting buildings from flood damage. In order to meet this goal, the federal emergency management agency (FEMA) has specific design requirements for new construction, as well as substantially damaged or substantially improved structures within special flood hazard areas. One key component of minimizing damage during the base flood is the use of openings in foundation and enclosure walls in order to prevent structural collapse due to hydrostatic forces.
FEMA has established a methodology to design these flood openings that will lower a buildings vulnerability to flood damage. Flood openings perform the critical task of equalizing water levels on the inside and outside of walls. This results in a reduction in the potential for differential pressure against walls that could result in failure. All walls and enclosed areas below the base flood must meet certain criteria in order to be in compliance with the NFIP.
This course provides guidance for the design, selection, and review of FEMA compliant flood openings.
This course is intended for practicing engineers, contractors, developers, governmental agencies, regulators, and all other personnel involved with the design, permitting and approval of structures near the floodplain.
To earn PDH credit, the student must pass a multiple-choice quiz consisting of fifteen (15) questions.
