Coastal Building Performance in Hurricane Isabel: Backward Trends in Design
The design and construction of hurricane-resistant construction has substantially evolved over the last 50 years. Early efforts included hurricane-specific building code standards in South Florida and North Carolina. Those were followed by development and gradual refinement of national standards and codes such as ASCE 7 and the International Building Code/International Residential Code. Along the way Congress created the National Flood Insurance Program (NFIP) that mapped flood hazards along hurricane-prone shorelines on a national basis and required local adoption of construction standards in exchange for the availability of nationally subsidized flood insurance. Post-storm building performance reports have been prepared by the National Research Council's Committee on Natural Disasters and later FEMA's post-storm Building Performance Assessment Teams. Advisory documents such as FEMA's Coastal Construction Manual (2000), now in its third edition, have been developed to identify construction weaknesses and offer voluntary guidance on how to build more storm-resistant buildings. Design guidelines and standards have gradually improved over time as a result of observed building performance during storms and improved science. However, Hurricane Isabel in 2003 offers an opportunity to observe recent steps backward in design improvements in North Carolina. This paper reports on coastal flood, wave and erosion damage, the most severe causes of damage in Isabel. Several causes of the backward trends are identified.
