![]() Their study focused on 1,000 hypothetical homes in Selinsgrove, Pennsylvania where river flooding is a consistent concern. Geological Survey and a framework-called a multi-objective robust decision-making method-the researchers analyzed the complex interactions of uncertainties and different cost-benefit trade-offs to assess whether they might improve on FEMA’s suggested elevation. The homeowner will raise the house a total of 11′ and has received the Increased Cost of Compliance (ICC) benefit included with his National Flood Insurance Program (NFIP) policy because of his compliance to the community’s floodplain management ordinance. New Orleans, LA, Ma– This house in Gentilly is in the process of being elevated above the base flood elevation adopted by the community in result of flooding from Hurricane Katrina. This is the minimum elevation for which federal funding may be available.īut determining how high to elevate a house requires homeowners to consider the costs and benefits of doing so, which depend on uncertainties such as future flood hazards in the context of climate variability and change, the future value of money, and building vulnerabilities like structural durability. FEMA recommends elevating houses to the height of a flood that has a one percent chance of occurring in a given year, also known as the 100-year flood, plus at least one foot. Homeowners in river flood zones are looking for good strategies on how high to elevate their houses. “Some houses are elevated high, some to intermediate levels and some not at all. “Many houses located along rivers in Pennsylvania are in danger of being flooded,” said Klaus Keller, co-lead of CPO’s Mid-Atlantic Regional Integrated Sciences and Assessments (MARISA) team and Penn State Professor. The findings were reported today in Nature Communications. Now new research supported by NOAA’s Climate Program Office (CPO) and led by Penn State University suggests that, in the face of economic, engineering, and environmental uncertainties, homeowners would reduce the most damage by raising their homes beyond the minimum guidelines recommended by the Federal Emergency Management Agency (FEMA). To manage that risk, people who live in areas designated as river flood zones often seek to raise their homes-but exactly how high to elevate their homes is both a critical and complicated decision. Millions of Americans have properties facing the threat of destructive floods, with a cost of up to $25,000 in damages for just one inch of floodwater. Record rains swelled many western Washington Rivers that breached their levees and flooded roads, property and towns. 11, 2006 - Mitch McKron pumps water from the basement of his mitigated home that he had just raised in time to prevent it from flooding.
