BREAKAWAY WALLS DEFINITION FILM PROFESSIONAL
If breakaway walls are used to enclose areas below the building that exceed a design safe loading resistance of 20 pounds per square feet, those walls must also be certified by the registered professional engineer or architect. The community must maintain a copy of this certification in the permit file for all structures built or substantially improved in the V Zone. Not only do they have to be elevated above the Base Flood Elevation (BFE), they must be protected from the impact of waves, hurricane-force winds and erosion.Ī registered professional engineer or architect must certify that the design and planned methods of construction meet NFIP requirements. Buildings in V Zones are subject to a greater hazard than buildings built in other types of floodplains.
National Flood Insurance Progam (NFIP) regulations require coastal communities to ensure that buildings built in V Zones are anchored to resist wind and water loads acting simultaneously.
