Building 120
Background
The City of Sammamish owns the facility located at 120 228th Ave NE, previously leased to Central Washington University (CWU) for higher education programming. CWU elected not to renew its lease and vacated the facility in June 2025. The City resumed full control of the property on July 1, 2025 and extended existing subleases to minimize disruption for current users. Most were not renewed for an additional term and expired July 1, 2026 except for the YMCA and Microsoft's parking lot lease.
The building is not currently available for rentals.
Current Work
City Council heard an update from Staff on September 15, 2026. Watch the presentation and following discussion here.
The City is also taking the site through the rezone process, more information about the rezone can be found here, including the link to the SEPA Comment form.
Original Project Scope
The City was asked to evaluate the future of Building 120 and its surrounding site. This work will help determine whether the existing building can be repurposed for community purposes, be better suited for other options, or if the City should sell the property. The City Council approved a contract for this work on January 20, 2026.
The work is to be completed in three phases and at the end of each phase, the City Council will review progress and decide whether to move the project forward to the next step or end the project. The three phases are below:
Phase 1: Building & Site Assessment
Engineers and architects will complete a full review of the building’s safety, structure, accessibility, systems, and site conditions. They will also estimate repair and upgrade costs and conduct a market analysis to understand community needs. The City Council will review these findings before deciding whether to move to Phase 2.
Phase 2: Community Engagement
If Phase 1 supports moving forward, the City will gather community input through public meetings, surveys, and stakeholder discussions. Engagement will focus on realistic, site-appropriate options—either for reusing the building or planning for the site if reuse isn’t feasible. Council will then determine whether to proceed to Phase 3.
Phase 3: Feasibility & Recommendations
The final phase brings together all technical findings and community input into a feasibility plan. This includes conceptual designs, cost and funding considerations, and operational needs. The results will be shared with the public and City Council, who will determine next steps for the property.
Project Updates
Phase 1: Completed
The consultant team conducted a full technical assessment of the building and property to determine whether it is safe, functional, and cost-effective for community use. The building was found to be structurally sound and its major systems remain functional, though many are aging. The consultant presented their findings at the April 21, 2026 City Council meeting. The consultant's presentation and assessment report can be found here.
City Council Action: Motion was passed to include additional options to explore in the scope of work including selling the property, converting for mixed use, include Big Rock Park South in the market analysis, ground leases, city annex, and sustainability upgrades.
Phase 2: Paused
