Washington Builders Limit Runoff From Record Rainfall
Record-breaking rainfall in the Northwest inundated parking lots and overwhelmed storm water management systems in Washington state two weeks ago, but the Kitsap Home Builders Association came through unscathed thanks to pervious pavements, a rain garden and other low-impact development features installed by member volunteers that kept excess water at bay.
In 48 hours, the Bremerton, Wash. area was saturated by about 13 inches of precipitation, a record even for the rainy Northwest, or at least for the city itself, said the association’s executive director, Art Castle. “When I came in to work Monday morning, the rainfall was still at its peak and I saw a river running down the street,” he said. But at the HBA headquarters, “there was no surface runoff from the site,” he said.
