Public Safety and Maintenance Facility Project

At the February 4, 2025, City Council Planning Session the Public Safety and Maintenance Facility (PSM) design team gave the City Council an update on the progress of schematic design of the PSM Facility. 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.

Once City Council gave direction to begin planning for the Public Safety and Maintenance Facility, staff and the City’s architectural consultant team, Northwest Studio, have conducted workshops with the City teams anticipated to be housed in the future PSM building. This pre-design work considered 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

In the fall of 2024, 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 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.

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.

In the fall of 2024, 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.

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.

The project team will continue to learn from comparable sites and neighboring agencies as the design process progresses.

In early 2023, the City of Mercer Island began working on Facilities Conditions Assessments to guide future investment decisions for City facilities and the development of a Long-Range Facilities Plan. These assessments include Mercer Island City Hall, the Public Works Building, the Mercer Island Community and Event Center Annex Building, the Luther Burbank Administrative Building, the Mercer Island Thrift Shop building, and the former Tully’s Building. The assessments were to be used to prioritize a comprehensive plan to maintain, repair or replace these buildings to ensure City facilities can deliver municipal programs and services for the next 50 years.

In April 2023, and in the midst of beginning the Facilities Conditions Assessments, an asbestos contamination was discovered in the City Hall/Police Station facility. Staff was immediately relocated from the building while several months of testing took place in the building. Testing resulted in asbestos detection in several locations in the building, including in the HVAC system. No airborne asbestos was detected during air quality tests.

City staff and outside experts worked extensively to identify solutions to address the asbestos contamination and evaluate the best path forward for City Hall. Two scenarios for re-occupying the City Hall building, either fully or partially, were evaluated for timeline, preliminary costs, and impact to City operations. Unfortunately, the cost of both scenarios to re-occupy City Hall exceeded the benefits due to the age and condition of the building and the City Manager was directed to permanently close City Hall. Please find more information about the asbestos discovery and closure of City Hall here.

Due to the emergency closure of City Hall, FCA work was reprioritized to meet the most pressing needs. Given the age and condition of the Public Works Building, the City Manager directed staff and consultants to complete a FCA for this building, while pausing assessment work on the other buildings.

The assessment identified multiple systems that are failing or in need of significant repair or investment. This information was presented to the City Council on February 6, 2024 (AB 6402).

Combined with the City’s urgent space needs for teams displaced by the City Hall closure, the City Manager recommended that the Council prioritize the Public Works Building for replacement, and to address the critical need for permanent police facilities. Council’s direction allowed the City Manager to proceed with building this new facility on the existing campus. Preliminary programming and designed work commenced immediately with Northwest Studio, the architectural firm already on board for long-range facility planning.
