Project Status

Thank you Seattle! This project is complete.
Thank you to everyone who attended the opening celebration on July 25, 2015. Enjoy your new park!

The 20-acre expansion of the park captures panoramic views of the mountains and city skyline, while integrating a range of multi-generational amenities. Features include a flexible great lawn, a new play area with two zip-lines and hillside slides, swaths of native prairie, strolling paths, parking and streetscape improvements, restrooms, and public art. A mix of oak species will provide strategic shading, frame views and contribute to Seattles urban forest and habitat for generations to come. Site Workshop collaborated with the community, Seattle Parks and Recreation and SPU on designing the park and Mid-Mountain Contractors constructed the park.

Spring 2015
Seattle Public Utilities(SPU) completed the work on the interior of the reservoir in early March as anticipated.  Mid-Mountain Contractors returned to the site in mid-March and will work until completion.  It's anticipated that they will finish the work  by the end of May.  The freshly seeded turf will need some time to grow before the full park can be open for use.  We'll keep a close eye on the establishment of the turf and open the park as soon as possible.

Winter/Spring 2015
The project is nearly complete. The fencing will remain up to allow the turf to establish. SPU has a repair project inside the reservoir and they are using the north end of the site for access and staging. Their work will be complete in March. At that time, Parks will complete the park improvements at the north end.

Summer 2014
The contractor is moving full force ahead with the construction of the park. The focus began on the play area and within the interior of the park. Next, the contractor will focus work on the western side and complete the parking lot and street improvements along 8th Ave. SW and Trenton SW. Feel free to peek through the fence and view the changes as the park comes to life!

Spring 2014
Mid-Mountain Contractors have been awarded the construction contract. Notice to proceed was given in February. In order to avoid the rainy season, the contractor requested mobilizing on site in May. Construction will continue through the summer months.

The Parks and Green Spaces Oversight Committee approved an additional $421,000 in funding to pay for street improvements required by DPD as part of project permitting.

These include sidewalk, curb and gutter along the south side of SW Cloverdale St from 8th Ave SW to the new park entry east of 7th Ave SW and a sidewalk along the east side of 8th Ave SW between SW Cloverdale St and SW Trenton St.

Design Development drawings were reviewed by Seattle Public Utilities (SPU) in February 2012, and Parks and Site Workshop set direction for addressing their specific concerns.

The revised project schedule is to complete construction documents in September 2012, and to start construction in March 2013. In the meantime, SPU has opened the site for public access. The public is welcome to enjoy the site for passive recreation, subject to park rules.

Park improvements funded by this project include pathways, parking lot, restrooms, a relocated play area, and landscaping. In addition, Department of Neighborhoods will be constructing the P-Patch in Westcrest Park featured in our schematic design. This feature is funded by the community garden funding included in the Parks and Green Spaces Levy.

Project Description

This project develops an overall site plan and implements improvements to transform the 20 acres of open space on the reservoir lid into a new neighborhood park and gathering space for southwest Seattle. The project will include artwork commissioned with 2008 Parks & Green Spaces Levy and SPU 1% for Art funds and administered by the Office of Arts & Cultural Affairs.

Seattle Public Utilities(SPU) is replacing its open reservoirs with underground structures that will improve the quality and security of our water supply and provide new public open spaces on reservoir lids throughout Seattle.

Lid construction was completed in 2011 by Seattle Public Utilities with park construction anticipated to start in 2012.
