Just over five miles long and two miles wide, Mercer Island is a true island community consisting of high quality residential areas, preserved parks and open space, as well as miles of developed shoreline. Incorporated in July 1960, the Island has its own sense of identity, distinct from its neighbors, Seattle and Bellevue. With a population of just over 24,000, Mercer Island has been widely recognized as one of the premier residential communities in the State of Washington.
The City of Mercer Island has a Council-Manager form of government with seven City Council members, who are all elected at large for staggered four-year terms. The Council elects the Mayor from its members. The City Manager, who serves as the chief executive officer, is responsible for implementing the policies and goals of the City Council and provides leadership, coordination and development of City departments. The City Manager is appointed by, reports directly to, and serves at the pleasure of the City Council.
