FOLLOWUP: Milestone for Holden Natural Drainage System project, and a chance for Q&A about it

That’s the Highland Park area where Seattle Public Utilities plans to install the project known as the Holden Natural Drainage Systems. It’s now reached a design milestone, and construction could start before the year ends. With that in mind, SPU has announced a drop-in info session for a week from tomorrow:

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.

Spring Drop-In Session:
Time & Date: Saturday, May 31, 11 a.m. to 1 p.m.
Location: BedHead Coffee, 1513 SW Holden St
Contact: Wan-Yee Kuo, Project Manager, at Wan-Yee.Kuo@seattle.gov or 206-684-3957

The drop-in session will provide an opportunity for community members to learn about the final design, what to expect during construction, and ask questions and share comments with members from the project team.

Three days before that, the project will also be on the agenda for next Wednesday’s HPAC meeting, 6:30 pm at Delridge Library (5423 Delridge Way SW). The NDS project has already been in the planning phase for almost three years.

    Last email said the design was at 30%? Now we’re at final design? I look forward to all the cut through traffic on 17th and Kenyon with no left turn pocket being added when they narrow Holden.
