Coastal Homes: Critical Design and Construction Issues
Development along coastal areas over the last several decades has placed a number of homes in environments with wind driven rain, high winds, storm surge, flooding, and erosion. Many of these homes have been built to inland standards and are unlikely to survive coastal conditions and storms. Newer homes may be built to wind-resistant standards, but most will benefit from additional details that improve performance. FEMA and HUD have sponsored the development of a Home Builder's Coastal Construction Guide (HBCCG) for release in 2002. Selected topics from the HBCCG that are frequent problems are presented. Poor control of water and moisture intrusion leads to mold, mildew, or even structural damages. Secondary barriers for moisture control and water intrusion are discussed, including common misunderstandings and recommended usage and installation. Positive connections provide a continuous load path throughout the structure to resist lateral and uplift loads. Typical practices for sheathing and framing connections are compared to recommended approaches. Frequently, hurricanes cause extensive damages to homes by failing weaker cladding elements. Common initial failure points of the building envelope will be discussed and possible alternative presented. Careful home siting and foundation construction minimizes exposure to damages, particularly storm surge and erosion. Considerations for home siting and recommended foundations for A and V flood zones are discussed, with particular emphasis on pile foundations.
