SPU presents update on Ballard Natural Drainage Project
Seattle Public Utilities hosted a meeting with Ballardites Feb. 23 to discuss the progress of the Ballard Natural Drainage Systems Project that will one day prevent one million gallons of storm water from entering Salmon Bay.
The meeting was held at the Loyal l Heights Community Center and Ballardites showed up with questions about the project.
SPU representatives Emily Reardon, Grace Manzano, and Rachel Garret presented the progress and project changes to neighborhood members.
Since a project update last November, SPU has decided on a new garden design that has more capacity and changes the number of beds (cells) needed for the project. The new design is a modular subsurface cell system that extends underneath sidewalks, providing more space for water containment. Because of the added capacity, now SPU has determined that 17 city blocks are needed instead of the 22 originally planned. 40 cells will be constructed on those blocks. The 17 blocks were determined a ‘best fit” by the soil composition in the areas and already placed utilities. In projects like this, SPU aims to cause the least amount of infrastructure disruption as possible.
