Description Approximately 40,000 to 45,000 vehicles and a large number of pedestrians use a three-mile stretch of Aurora Avenue (Highway 99) between North 145th Street and North 205th Street in Shoreline, Washington every day. Much of the area lacked sidewalks and the wide roadway transitioned directly into parking for businesses along both sides of the street. Between 1992 and 1996, vehicles struck 42 pedestrians and 38 percent of those accidents were fatal or disabling. Buildings, roadways, and parking lots covered approximately 97 percent of the area in hardened surfaces. During storms, or heavy rain events, stormwater runoff from these surfaces flowed directly into nearby waters with little to no water quality treatment. The inadequate stormwater system also contributed to downstream flooding, erosion, and pollution problems. The city’s initial goal was to address pedestrian and traffic safety concerns. They also wanted to help improve the local economy, the environment, and replace the inadequate stormwater system at the same time. This project provided them with an opportunity to incorporate Low Impact Development (LID) structures to help them meet all of their goals.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
