Areas seaward of the LiMWA are subject to waves greater than 1.5 ft but less than 3 ft. Post-disaster building inspections and scientific studies have shown that waves greater than 1.5 ft are sufficient to induce structural damage to many National Flood Insurance Program compliant structures on shallow or solid wall foundations. The FEMA Coastal Construction Manual, American Society of Civil Engineers, and 2012 International Residential Building Code recommend Zone VE construction practices inside of the LiMWA. As part of the long term recovery effort, the Advisory LiMWA is a tool for Federal, State, and local officials, building officials, builders and architects, insurance professionals, and property owners to make informed decisions during rebuilding and to mitigate losses from future flood events, safeguard lives, and protect the private and public investment in rebuilding.", "description": "The Federal Emergency Management Agency (FEMA) has developed the Advisory Limit of Moderate Wave Action (LiMWA) to approximate the landward limit of the 1.5 foot breaking wave. The LiMWA defines the landward boundary of the Coastal A Zone Area, or the Area of Moderate Wave Action (MOWA ). Wave model output was reviewed and analyzed for the delineation of the LiMWA line.", "summary": "The Advisory LiMWA is intended to serve as the best available data for understanding coastal flood hazard risk and the elevations that communities should build to in order to protect themselves from future coastal flood events.
