The CSC undertook an eighteen-month study on the revitalization of the Fort Washington Office Park, located in Upper Dublin Township, Montgomery County. The estimate of 41 million people does not include the millions of additional Americans that are at risk of coastal flooding.Fort Washington Area Flooding and Transportation Improvement Study The new study analyzes and identifies only those at risk from flooding from rivers. We need comprehensive approaches to reduce the devastating effects that flooding has on so many communities." "Protecting and restoring the natural infrastructure of floodplains provides an important complement to built infrastructure like dams and levees. ![]() He added: "Floodplains provide high quality habitats for wildlife, they can offer outstanding recreational opportunities for people, and they help improve water quality. Consequently, the National Flood Insurance Program is now $24.6 billion into debt, not even counting the projected $16 billion cost of hurricanes Harvey and Irma last year. Johnson said avoiding future losses is particularly important as average flood losses in the U.S have increased steadily to nearly $10 billion annually. Floodplains also store and convey floodwaters, which can help prevent flooding in nearby communities." "Protecting floodplains or developing them in ways that can withstand flooding-such as flood-tolerant parks-can prevent unnecessary risk to people and help avoid expensive damage to property and infrastructure. ![]() The study-which integrates new maps from the Environmental Protection Agency that more precisely estimate where people live now and where future population growth is expected-predicts that under potential population growth and development projections, more than 60 million Americans may be vulnerable to a 100-year flood by 2050. This research will help fill this critical information gap."Īnother key concern, Wing says, is that people continue to build in harm's way, often without realising they are doing so. It's particularly worrisome considering that most of these people aren't even aware of the risk they face. He added: "We were all surprised by how many Americans we found are exposed to flooding from rivers. student at the University of Bristol's School of Geographical Sciences, said that not only is the model is able to produce flood risk maps across the country, its level of accuracy on smaller scales-that is, along specific rivers-compares well with FEMA flood maps that presently serve as the primary source of flood hazard data in the U.S. Oliver Wing, the lead researcher behind the study and a Ph.D. The increase in numbers of those at risk is a result of the expanded coverage of the map combined with its ability to estimate flooding on small streams-something that wasn't adequately captured in previous flood-risk models, according to the study's researchers. The study, published today in the journal Environmental Research Letters, is based on a new high-resolution model that maps flood risk across the entire continental United States, whereas the existing regulatory flood maps produced by the Federal Emergency Management Agency (FEMA) cover about 60 percent of the continental U.S. ![]()
