Wall section of breakaway walls and piers12/28/2023 Codes also require that homes in high-velocity wave action zones be supported on piles, columns or shear walls. Subsequent code renditions have addressed load paths in buildings in coastal areas. In Florida, roof straps that connect a home’s roof to the foundation became mandatory in areas where 120 mph winds can be expected. In addition, all new homes in areas where wind speeds equal or exceed 110 mph now must meet storm-resistant standards. The 2000 International Residential Building Code (IRC), for example, established a requirement for the use of impact-resistant doors and windows in hurricane-prone areas. Certainly, building codes became dramatically more stringent following such past major hurricanes as Andrew and Katrina. Ed Hudson, director of Marketing Research at the Home Innovation Research Labs Eventually, he says, it should also impact building codes. Overall, it will put pressure on and constrain building material supply for a while, which could up the price of building materials, which could cause an uptick in the price of housing.”Ĭodes will be modified and there will likely be a much higher consciousness now for building flood-resistant structures. This could cause delays if certain materials must go on allocation. However, the short-term view is clearer: New home buyers in the future will be more aware of the risks of damage from storms and floods - and builders, building code officials and product manufacturers will continue to work together to create solutions that result in safer homes.Įd Hudson, director of Marketing Research at the Home Innovation Research Labs in Upper Marlboro, Md., summarizes his predictions: “There is going to be a huge remediation business at first. The long-term impact of these massive storms will have on home building in hurricane-prone areas and in the refinement of building codes has yet to be determined. there are a few gems that survived and one was in the shadow of the water tower than is now on the ground.The recovery in Houston and Florida from Hurricanes Harvey and Irma has just begun. There are several miles of homes destroyed and now being rebuilt, hopefully better than the original loose conctruction requirements. Wood piling snapped at about 5' up if they did not tilt first, steel posts bent because the load duration was long and the exposure/corrosion was severe. In the rebuilding of the Ocean Beach(?) area of Mississippi, there are many good examples learned by experience based on the 20+' surge. Wood is not too effective because of the climate and exposure. Because of the climate, use and finishing options, concrete masonry 6" or 8" is used for the blow-out walls that are parallel to the typical surge direction. Between the piers/column there are usually walls on slab that are built to provide the normal separation and protection from the elements under normal conditions. The rectangular pier/columns are normally oriented to resist the surges. The better homes and apartments/condos are built using concrete masonry or reinforced rectangular concrete piers on spread footings below the normal water level. The amount of connection is limited, but if the wall stands, it can be easily cleaned and refinished if it is made from appropriate materials. Blow out walls on the Gulf coast are usually used on property near the water that is subjected to tides and storm surge.īecause they are designed to be weak, the only provide separation of areas.
