![]() In either case, the designer must certify both of the following: Breakaway wall collapse shall result from a water load less than that which would occur during the base flood The elevated portion of the building and supporting foundation system shall not be subject to collapse, displacement, or other structural damage due to the effects of wind and water loads acting simultaneously on all building components (structural and nonstructural). The need for greater loading resistance could be a result of design requirements or required by local or state codes. The regulations allow walls with a greater loading resistance under certain conditions, and when the design is certified by a registered professional engineer or architect. To ensure that breakaway walls withstand forces from wind and everyday use, yet collapse under storm conditions, current NFIP regulations require that a breakaway wall shall have a design safe loading resistance of not less than 10 and no more than 20 pounds per square foot. A breakaway wall is a wall that is not part of the structural support of the building, intended through its design and construction to collapse under specific lateral (wind and water) loading conditions without causing collapse, displacement, or other structural damage to the elevated portion of the building or supporting foundation system. Uses such as parking of vehicles, building access, or storage are permitted, as long as the walls of any enclosures are designed as "breakaway". In recognition of the desirability of using the sheltered space beneath elevated structures, NFIP regulations permit certain limited uses of enclosed space below the BFE. When the space below the lowest elevated floor is maintained free of solid obstructions as well, the potential for damage from waves or debris is further reduced. You can look up your base flood elevation here.1 Breakaway Walls Elevation of a structure on a properly designed foundation reduces the potential for water damage from flooding. For example, foundations must be pilings or columns rather than a solid block foundation and garage slab’s must be thinner (no more than 4 inches) and not pilings supported. The good news is, the majority of Beach Haven West is located in the A flood zone which offers more manageable costs and less stringent building guidelines.Īs mentioned above, homes that are located in the V zone also have different building guidelines. These homes are considered to be more risky, and will typically see a higher cost of flood insurance. In order for a property to be classified as a V zone, the home must be at risk of a sustained wave impact of 3 feet or greater. A flood zones are the most common zone in Beach Haven West.V zones have special building requirements.Areas in the V flood zone will typically see a higher cost of insurance.There are some important differences between the A and V flood zone. Special Considerations for V Flood Zones in the Beach Haven West Real Estate MarketįEMA’s flood maps that they need certain areas to be in a special flood hazard zone, and then further delineate the flood zone in which a home is located. The idea behind the breakaway wall, is that if a home sustains directly impacts or higher wind velocities, the foundation walls will breakaway allowing water to pass freely among the piling foundation. Rather, a home must have breakaway walls anything or garage slab, usually no more than 4 inches. A home in the V zone is generally not permitted to have a solid foundation, nor is allowed to have a pilings supported garage. The V zone in Beach Haven West is more restrictive and can have a negative impact on the property value in the Beach Haven West real estate market. Homes that are built in the A zone had more lacks building requirements, for example they do not need breakaway walls which can make the cost of raising a home far less expensive. There are some areas of Beach Haven West where the ground is about 6 feet high already, so these homes may not require any further raising. In most cases, homes that are located in the A zone will be the first for elevation of between seven and 9 feet above sea level. The A zone, which can be further broken down to AE or AO zones, is the most common flood zone. ![]() ![]() There are two primary flood zones in Beach Haven West. ![]()
