Longfellow Creek Natural Drainage System (NDS) Project
Enhancing our communities with natural drainage systems and pedestrian improvements.
Welcome to the Longfellow Creek NDS Online Open House!
When it rains in the Delridge and Westwood neighborhoods, pollution from our streets runs into Longfellow Creek untreated. This is not healthy for the creek or for people. The good news is that there is something we can do!
Natural Drainage Systems consist of shallow depressions in the public right-of-way, or “planter strip,” filled with deep-rooted plants and spongy soils that temporarily hold and clean polluted stormwater from
streets and sidewalks. These features capture and clean pollutants before they can reach the creek.
Seattle Public Utilities (SPU) is planning to build natural drainage systems in your neighborhood in 2021. For this project, we are partnering with Seattle Department of Transportation (SDOT), Office of Arts & Culture through 1% for the Arts, and King County Flood Control District.
