Mercer Island City Hall

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 as Proposition No. 1. Proposition No. 1 received 54.24% voter approval, which was short of the 60% needed for a successful bond measure. The City Council is currently reframing the approach to replacing City facilities and planning for community engagement.
  • 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.

  • December 2022 - City Conducts Request for Proposals Process for Long-Range Facilities Planning

    In December of 2022, the City launched a Request for Proposals (RFP) process to complete a Facilities Conditions Assessment for various municipal buildings and to lead the development of a Long-Range Facilities Plan for select City facilities. The scope of work includes Mercer Island City Hall, the Public Works Building, the Mercer Island Community & Event Center Annex Building, the Luther Burbank Administrative Building, the Mercer Island Thrift Shop, and the former Tully’s Building.

    The project is structured in two phases, the first being the Facilities Conditions Assessment performed in 2023. The assessment and accompanying data and analysis will be used to prioritize a comprehensive repair, alteration, and improvement budget for extending building life for 50 years. The outcomes from the Facilities Conditions Assessment will help shape and guide the second phase of work, anticipated in 2024, which will include development of a Long-Range Facilities Plan for select facilities.

    The City sent the Request for Proposals to 29 firms known to have experience or expertise in building condition analysis and future facilities planning. Eight firms responded and the City selected four of these to interview. Based on these interviews by a panel of City staff, Northwest Studio was selected for the Facilities Conditions Assessment and Long-Range Facilities Planning project in March 2023.

    The scope of work and phasing has changed slightly due to evolving needs related to the emergency closure of City Hall. The long-term planning portion of the project will include scenarios for replacement of City Hall, as well as meeting the original intent of guiding City Council decisions on other City buildings.
