110 Cascade
Seattle Public Utilities and Seattle Department of Transportation replaced the existing ditch and culvert system along 4 blocks of Northwest 110th Street, between Greenwood Avenue North and Third Avenue Northwest in the Piper's Creek Watershed with a "Cascade" model natural drainage system as part of the Street Edge Alternatives program. An online tour of the Street Edge Alternatives program is provided by the City of Seattle. Vegetation and swales that form part of the system help to filter out and break down polluted runoff, before the water reaches Pipers Creek. The project is a series of stair-stepped natural pools that slow damaging stormwater flows, reduce flooding, and trap pollutants before they reach Piper's Creek. Stormwater flow from approximately 21 acres is managed through this natural infrastructure. (from Seattle Public Utilities)
