The Holden Natural Drainage Systems (NDS) Project has reached final design. SPU will build natural drainage systems, also known as roadside rain gardens or bioretention, on SW Holden St between 16 th Ave SW and 17 th Ave SW. The NDS will capture and treat stormwater runoff before it reaches Longfellow Creek and Puget Sound. The goal of the project is to improve water quality in the creek, increase landscaping diversity, and provide roadway and pedestrian safety improvements. Construction is anticipated to start in late 2025. To learn more about this project, please visit our website.
