The City of Mercer Island, Washington is soliciting Statements of Qualifications through a Request for Qualifications for design and construction support services for Phase I and II improvements at Deane's Children's Park. A non-mandatory site visit is scheduled for November 17, 2026 at 1:00 p.m., and SOQs are due December 4, 2026 at 5:00 p.m. through the City's OpenGov procurement portal.
