Map of Mercer Island

Mercer Island is a city in King County, Washington, United States, located on an island of the same name in the southern portion of Lake Washington. Mercer Island is in the Seattle metropolitan area,^[6] with Seattle to its west and Bellevue to its east.

The island is connected to the mainland on both sides by bridges carrying Interstate 90, with the city of Seattle to the west and the city of Bellevue to the east. The Lacey V. Murrow Memorial Bridge and the parallel Homer M. Hadley Memorial Bridge are floating bridges that span Lake Washington and carry, respectively, eastbound and westbound lanes of Interstate 90 and connect Mercer Island to the northern portion of Seattle's South End. I-90 traverses the northern portion of Mercer Island and is then carried from the island to Bellevue over the East Channel of Lake Washington by the East Channel Bridge. Mercer Island is located closer to Bellevue than it is to Seattle, and is therefore often considered to be part of King County's Eastside.

The population was 25,748 at the 2020 census.^[4] Mercer Island has the fifth highest per-capita income in the state of Washington^{[citation needed]} and is one of the 100 richest ZIP codes in the US according to the IRS figures for Adjusted Gross Income.^[7]

History

The western side of the island was home to two Snoqualmie villages prior to white settlement in the Puget Sound region.^[8] Mercer Island, named for the Mercer family of Seattle, was first settled by non-indigenous people between 1870 and 1880. The Mercer brothers often rowed between the island and Seattle to pick berries, hunt, and fish. Those brothers, Thomas Mercer and Asa Mercer, were members of the Mercer family of Virginia. The first large settlement, East Seattle, was toward the northwest side of the island—near the McGilvara neighborhood. During 1889, a C.C. Calkins built a large and gilded resort, the Calkins Hotel. The hotel was reached via steamboat between Madison Park, Leschi Park, and the Eastside. Guests included President Benjamin Harrison, of 1901, amongst other well-to-do dignitaries from Seattle to the East Coast of the United States. Burned by a mysterious fire, the hotel was razed during 1908.

The Calkins Landing continued service and presumably aided the establishment of a more permanent population. A denser urban community with business district developed toward the central northern island between the McGilvra neighborhood and Luther Burbank Park. This community now composes the majority of the island's crest through the Middle Island neighborhood.

In 1923, the East Channel Bridge was built to connect the island with Bellevue. In 1930, George W. Lightfoot requested a bridge between Mercer Island and Seattle. The Lacey V. Murrow Memorial Bridge, currently the second longest floating bridge in the world, was built and opened in 1940. In 1989, a second bridge, the Homer M. Hadley Memorial Bridge, was built parallel to the Lacey V. Murrow Memorial Bridge. The East Channel Bridge, Lacey V. Murrow Memorial Bridge, and Homer M. Hadley Memorial Bridge, carry Interstate 90 from Seattle, across Mercer Island, and into Bellevue.

The City of Mercer Island was incorporated from East Seattle on July 5, 1960, and comprised all the island minus the 70-acre (280,000 m²) business district. Just over one month later, August 9, the Town of Mercer Island was incorporated from that business district. The two aforementioned municipalities merged as the City of Mercer Island on May 19, 1970.

Government

Mercer Island uses a Council–manager government and the city council selects the mayor. The City Hall building in the northeast part of the city hosts offices for the City Manager and most local administrative employees, the municipal court, and the police department.

At the national level, Mercer Island is located in Washington's 9th congressional district, which is currently represented by Democrat Adam Smith. The City of Mercer Island is part of the 41st Legislative District, served by two State Representatives and one State Senator.

The Mercer Island Fire Department operates out of two facilities, both of which are close to Island Crest Way. The Mercer Island Police Department operates out of one facility, which is adjacent to I-90. The city operates neither a potable water treatment facility nor a wastewater treatment facility, the latter being handled by the King County Wastewater Treatment Division, which owns and operates a collector sewer around the island. The Public Works Department operates an office facility, street maintenance facility, and city shop from a building south of the City Hall.

In February 2021, a 6–1 majority of the Mercer Island City Council passed an ordinance prohibiting outdoor camping on public property, mainly to restrict homeless and unhoused people from overnight stays. The ordinance was criticized by the American Civil Liberties Union of Washington and other public advocates for the homeless.^[25][26]

Parks

Luther Burbank Park [ceb] covers 77 acres (310,000 m²) of land and has 0.75 miles (1.21 km) of waterfront. The park has a public boat dock and fishing pier, a swimming beach, an amphitheater, tennis courts, barbecues and picnic facilities, and an off-leash dog area.^[27] The city assumed maintenance of the park on January 1, 2003, from King County, which had purchased the park land in 1969.^[28]

The Aubrey Davis Park is atop the I-90 tunnel entrances. This park has softball fields, tennis courts, basketball courts, picnic shelters, and the Freeway Sculpture Park. Due to its location atop the I-90 tunnel, the park is also locally referred to as "The Lid." ^[29][30]

Pioneer Park covers 113 acres (0.46 km²) and has equestrian, bicycle, and hiking trails.^[31] Deane's Children's Park, also known as "Dragon Park", is a small park with playground equipment including a large concrete dragon structure.^[32]

Clarke Beach is located at the south end of Mercer Island and is home to the annual polar bear swim on New Year's Day.

Mercer Island also has many smaller parks maintained by the city, some of which have waterfront access. In 2010, the city built a well in Rotary Park to supply the area with water in the event of a major disaster, specifically an earthquake.^[33]

Transportation

Mercer Island is bisected by Interstate 90, which connects the city to Seattle in the west and Bellevue in the east. The freeway travels over the Lacey V. Murrow and Homer M. Hadley floating bridges over Lake Washington to Seattle and the East Channel Bridge towards Bellevue. The bridges also carry the Mountains to Sound Greenway, which includes a multi-purpose pedestrian and bicycle path. A significant section of the freeway is recessed below street level and covered by the Mercer Island Lid, which includes several parks.^[55]

The city's public transportation is provided by King County Metro and Sound Transit, mainly consisting of express bus routes to Seattle and the Eastside. Several routes connect to a park and ride on the north side of the island with 447 stalls.^[56] It was expanded into a two-story parking garage in 2008.^[57][58] All-day service for most of the island is provided by Metro Route 204, which is supplemented by Route 630 and several school bus routes during peak periods.^[59][60]

In early 2025, a light rail station at the park and ride facility will be opened by Sound Transit, providing service on the 2 Line to Seattle and the Eastside.^[61] The light rail line will replace several express routes on Interstate 90 and Mercer Island is expected to function as a major bus–rail interchange.^[56]
