Municipal Facility Planning
Over the past several years and following the unplanned closure of City Hall in 2023, the City of Mercer Island has been developing a comprehensive facilities plan to ensure continued and sustainable delivery of municipal programs and services to the residents of Mercer Island for the next 50+ years. The City is currently implementing two key strategies:
- A new Public Safety and Maintenance (PSM) Facility that will house the Police Department, the Emergency Operations Center, the Customer Service Counter, the Public Works Maintenance Teams and Yard, and the City’s IT and GIS teams. It will be constructed on the City Hall and Public Works Building site. A bond measure to fund the new PSM Facility will be presented to Mercer Island voters at the November 4, 2025 General Election.
- A recently acquired property at 9655 NE 36th Street, adjacent to the City Hall site, will eventually serve as the permanent location for additional City departments, including the Community Planning and Development Department, the Public Works Capital Projects and Engineering teams, and the Youth and Family Services Department.
Islanders are encouraged to stay informed on the facilities planning process here on Let’s Talk. You can review key documents, watch City Council meeting recordings, and view renderings of the proposed PSM Facility in the materials on this page.

April 15, 2025 City Council Meeting - Site Layout Review
Share April 15, 2025 City Council Meeting - Site Layout Review on Facebook Share April 15, 2025 City Council Meeting - Site Layout Review on Twitter Share April 15, 2025 City Council Meeting - Site Layout Review on Linkedin Email April 15, 2025 City Council Meeting - Site Layout Review linkDuring the April 15, 2025 City Council meeting, the PSM Design Team presented an updated site layout that will move the PSM Building (main administrative building) and the Operations Building north on the site. This strategy recommendation resulted from feedback from the City Council, and meetings with Police, Public Works, Emergency Operations, and IT/GIS staff in recent week.
See agenda materials and presentation linked here and the meeting recording linked here.
This proposed revision to the site layout will reduce construction costs, increase operational effectiveness, and leave room for potential future operational capacity to ensure that this facility is positioned to serve the city over the next 50-plus years.
City Council approved the new site layout and general alignment of the major amenities, recognizing that the design phase is still in the early stages and some refinement will be necessary as the design work continues.
Additionally, the proposed PSM Facility layout includes the placement of the Operations Building on top of the property line between the existing City Hall and Public Works parcels. The Design Team recommends a boundary line adjustment to move the parcel line north closer to SE 36th St (see graphic linked here). Both parcels comprising the current City Hall Campus have the correct comprehensive plan land use designation, which is “Public Facility.” The zoning, however, is different and this was identified for resolution as part of the PSM Facility development process.
The City Manager is recommending the new south parcel created by the boundary line adjustment be re-zoned to “Public Institution” (PI), consistent with other public facilities on Mercer Island. The north parcel is recommended to remain as CO to preserve flexibility for its future use.
The City Manager received formal direction to add this item to the work plan. The City Manager will work with staff and legal counsel to set this item for review in late 2025 or early 2026. The re-zone work will need to be complete before permits are submitted for the project (mid to late 2026).

See agenda materials and presentation linked here and the meeting recording linked here. The Design Team presented information on the following thematic areas:
- Planning for Potential Future Operational Capacity needs at the PSM Facility
- Functions and Uses of the Operations Building and Yard
- Alternative Construction Delivery Methods.
City staff and City Council discussed if the main PSM Building be pulled forward (north) to expand the capacity of the secure areas (parking and maintenance yard) behind the main PSM Building. Staff said this was an idea worth investigating further and committed to coming back with additional information at a future Council meeting.

Current planning for the new PSM anticipates the new building will house five key City functions: Police, Public Works and Maintenance, the Emergency Operations Center, IT & GIS, and the Customer Service Team.
The benefits of co-locating these departments include: improved operational and emergency response coordination, efficiency in co-locating protected and secured parking, significant overlap in common space needs, large spaces driven by specific departmental needs can be shared, and housing key public safety and emergency response capabilities in a building constructed to Risk Category IV that can continue operations after a significant seismic event.
For more information on programming needs of the building, see the presentation from the February 4th City Council planning session.

You can view the meeting materials here.
This is the first of several City Council discussions scheduled for this year to review and evaluate the PSM design. Additionally, the City plans to gather public input and feedback through a community engagement process later this year.
City staff and the architectural team, Northwest Studio, began the “schematic design” phase for the PSM facility last fall. Schematic design is the first step in taking a concept and turning it into a specific design plan, including architectural drawings and a site plan. Last October, Mayor Nice, Councilmember Weinberg, and the PSM design team toured Police Department facilities in Shoreline, the University of Washington campus, and Kirkland. The team heard about both successes and “lessons learned” from the construction or renovation of these police facilities to help inform work as we plan for our new facility.
In November, the PSM design team also led a site tour of the City Hall and Public Works Building properties for all subconsultants working on the project. This tour allowed the various specialty contractors of the design team – such as civil and structural engineering, landscaping, and architecture – to see the conditions and context of each property and ask questions of staff and design team leads.
Also in November, the PSM design team conducted a follow-up site visit with the City’s Public Works Department operational leads assess how the Public Works teams utilize the facility and yard space for equipment and materials storage. The visit focused on optimizing these areas in the new facility to enhance efficiency, improve service levels, and reduce operational costs.
The design team and Councilmembers Anderl and Jacobson toured the Kitsap County Public Works facility in December of 2024. This tour focused on their office space and training space layout, ingress/egress for large vehicles and equipment, covered storage, lighting, security, and staff amenity spaces.

You can review the agenda bill, the presentation, and the meeting recording is available here.
Staff provided an overview of the facilities and the circumstances leading to the design to design the PSM Facility. The City’s architect team Northwest Studio presented the early schematic design documents and cost estimates to the City Council. They also sought feedback from the City Council on design strategies and early design choices.
The design team presented a preliminary cost estimate of the PSM Facility, estimating that it will have a cost range between $105 and $110 million. This estimate includes constructions costs, soft costs, an escalation factor, and state and local sales tax.
A more detailed cost estimate will be prepared during the Schematic Design process as the building and site plans are further refined. The revised Schematic Design Cost estimate will be presented to the City Council in June 2025.

The Police Department has been significantly impacted by the closure of City Hall, which housed the police precinct. The City explored a number of alternatives for the Police Department, landing on leasing modular buildings. The lead time on these buildings was over a year. The Department initially relocated to the Mercer Island Community & Event Center and then over the summer moved to the Luther Burbank Building. The modular buildings opened for use in the fall of 2024.

At the March 1 Planning Session, City Council directed the City Manager to begin planning for a new Public Safety and Maintenance Building (PSM) on the current City Hall Campus (see AB 6420). This new facility will replace the existing Public Works Building and provide a new combined home for the City’s Public Works teams, Police Department, Emergency Operations Center, and IT & GIS.
Staff and the City’s architectural consultant team, Northwest Studio, have conducted workshops with the staff teams expected to be housed in the future PSM building to inform the ongoing design work. The pre-design work considers the spaces needed in the building, in addition to how the spaces are best organized to achieve efficient workflows, to plan for future growth, and to accommodate changing space needs over time.
The presentation also included an overview of Risk Category levels in building design. The risk category of a building reflects the relative resilience to natural disasters and other building failure risks. The new PSM building is intended to be a Level IV Risk Category Building. Risk Category IV includes buildings that are essential in that their continuous use is needed, particularly in response to disasters. Police stations and emergency vehicle garages, Emergency Operations Centers, public works staff areas, and equipment necessary for emergency response, must remain operational during and after major disaster type events.
The presentation concluded with a commitment to continue the work with Police, Public Works, EOC staff, and IT & GIS to gather feedback on design concepts and proposed building programming and workflow. City staff are preparing to return to the City Council in June to present preliminary design and siting concepts for the Public Safety and Maintenance building, including early cost estimates.

At the February 6, 2024 City Council meeting, City staff presented initial findings from the FCA and a high-level overview of the potential repairs and investments necessary to keep the Public Works building operational (see AB 6402). These include both critical systems repairs and basic safety, efficiency, and comfort centered upgrades. At the May 21, 2024 City Council meeting, City staff finalized the FCA report and presented initial findings from a detailed seismic analysis of the building.
While the results of these studies confirm the functional obsolescence of the existing Public Works building, it remains necessary to operate the facility for approximately five years while a new building and yard is designed, funding is secured for construction, and the project is completed. Near-term issues that will be addressed include:
- Completely remove the existing green roof and accumulated soil.
- Install anchoring between the walls and the wood diaphragms at the two higher level roofs (the second-floor office space and high bay garage).
- Install a subsurface concrete-grade beam along the exterior at each end of the high-bay garage doors.
- Retrofit numerous unbraced interior CMU (concrete masonry unit) walls throughout the building.
- Provide additional fire extinguishers or extinguishing systems throughout the building.
- Include fall restraint guards at the Public Works building and select outbuildings.
- Apply safety film to existing wired glass windows to prevent shattering.
City staff have started to address the priorities identified in the report to extend the useful life of the Public Works Building. Funding recommendations for the identified capital projects will be included for consideration this fall as part of the Biennial Budget Development process.
If occupancy of the Public Works building is anticipated to exceed five years, the next set of investments will be significant. Construction costs are expected to increase, and upgrades to meet current code requirements will become necessary, further expanding the cost of operating this facility at a minimally functional level.
