Issaquah is a city in King County, Washington, United States. The population was 37,322 in a 2016 census estimate. Located in a valley and bisected by Interstate 90, the city is bordered by the Sammamish Plateau to the north and the Issaquah Alps to the south.History"Issaquah" is an anglicized word for a local Native American name, meaning either "the sound of birds", "snake", or "little stream". "Squak Valley", an older name for the area, also derives from this same Native-American name.In 1885, the then unincorporated area was the scene of an attack on Chinese laborers who had come to pick hops from local fields. The city itself was officially incorporated on April 29, 1892. Initially a small mining town, this town has changed noticeably both in its appearance and economic focus. Issaquah was originally developed to service the mining industry on nearby Squak and Cougar mountain, and began as the town of Gilman, Washington. As the mining deposits neared depletion in the late 1890s, other companies started to realize Issaquah's potential to support a lucrative lumber business. These companies exported timber from Issaquah and other small, local towns to Seattle and larger, rapidly growing communities throughout western Washington. These early boom industries, however, faded into a period of relative quiet by the time of the Great Depression. The town remained fairly placid through the succeeding decades, with The Boeing Company providing the majority of employment in the area. Microsoft and other technological industries moved into Redmond, Washington and other cities in the area, and later established operations in Issaquah itself. Both Boeing and Microsoft have significantly affected Issaquah's history, cultural development, and diverse population through their active community participation and attraction of outside residents. In June 1996, Costco moved its global headquarters to Issaquah from nearby Kirkland, Washington.
