Bitter Lake Reservoir Park

Updated: July 12, 2024

Summer 2024

Thank you to everyone who shared their time and thoughts about the design of the additional open space around the new reservoir! The project design consultant completed a preferred concept design and a construction cost estimate at the end of May 2024. SPR is reviewing the details of the design and cost estimate before sharing the concept. It is anticipated the concept will be posted by the end of July 2024. SPR is anticipating that in late 2025 a design consultant will be hired to develop construction drawings and begin the permitting process. Construction of the open space improvements may begin in early 2029 after the completion of the reservoir.

This is a One Seattle effort to provide northwest Seattle with open space with public art and a new reservoir. Seattle Public Utilities (SPU) is building a new drinking water reservoir. This new 21-million-gallon reservoir will replace the existing reservoir that is reaching the end of its service life. The new reservoir will be partially buried and contain the same amount of water as the existing one but with a smaller footprint. This creates more than six acres of new open space after the reservoir construction is complete in 2028-2029.

Project Description

Seattle Public Utilities (SPU) is replacing the existing reservoir with a concrete tank that makes space for Seattle Parks and Recreation (SPR) to expand the park for the community. SPR is leading the park and open space design in coordination with SPU, the Office of Arts and Culture, and the Department of Neighborhoods. This project will incorporate elements of the existing park together with new recreation amenities, public art and a potential expansion of the P-Patch for the Bitter Lake neighborhood. We look forward to hearing your ideas!
