WHAT IS A FLOOD BARRIER?
A flood-barrier is a secondary flood-proofing system to be used when the design elevation of the building is below the Base Flood Elevation . The purpose is to form a watertight seal in front of all building openings in order to prevent floodwaters from penetrating the structure. This system is to be removable and only used at time of storm or flood warning and in conjunction with other flood-proofing design criteria. These design criteria are to meet or exceed the regulations and loads set forth in both the Army Corps. Of Engineers, Flood Proofing Regulations (85 page Pdf. File, approx 5Mb) and F.E.M.A., Flood-proofing Non-Residential Structures FEMA 102 / May 1986. Flood-barriers should be considered as a last resort in project design, and used only when all other flood proofing designs have been exhausted.
