The Department of Housing and Urban Development has announced the results of the $1 billion National Disaster Resilience Competition. Among the winning communities across the country was a flood mitigation proposal from Virginia; this proposal includes work carried out by students and faculty at Hampton University and Old Dominion University researching and developing solutions to combat the effects of flooding in Chesterfield Heights. These efforts are the focus of a session at NAPC’s FORUM 2016 in Mobile, AL, July 27-31.
More information on this project, which will be discussed in-depth at FORUM:
“Students developed a guide for homeowners proposing using any renovation time and funds between now and storm events to move utilities above first floor level, to remove water-holding materials on the first floor of the interior and talked through the prudence of giving up cherished basement areas to allow for their use as cisterns, something computationally useful in urban neighborhoods.
“Eventually an array of solutions were presented – from oyster reefs and living shorlines to increase protection from tidal wash, to under-street, and under-sidewalk cisterns to hold water until storm water system recovery after rainfalls, to small bio-retention swales in the street verge and parking defining elements, to an array of suggestions from under-lawn to basement cisterns and property line swales to keep all rain falling on each lot on that lot.
“Incredibly, when modeled using SWMM flood software, the combination of these interventions eliminated all existing flooding, and maintained this elimination with forecast models out to 2100.”
