Bitter Lake Reservoir Park

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.
