History

“Issaquah” is an anglicization of the Southern Lushootseed placename /sqʷáxʷ/, 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 September 1885, the then-unincorporated area was the scene of an attack on Chinese laborers who had come to pick hops from local fields. Three of the laborers died from gunshot wounds, and none of the attackers were convicted of any wrongdoing.

The city was officially incorporated on April 29, 1892. Initially a small mining town, the city has changed noticeably both in its appearance and economic focus. Issaquah was originally developed to service the mining industry (on the two nearby mountains that now lend their names to the Cougar/Squak Corridor Park), and began as the town of “Gilman”. 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 Boeing providing the majority of employment in the area. Microsoft and other technological industries moved into Redmond 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.

Geography

Issaquah is located 15 miles (24 km) east-southeast of Seattle at the south end of Lake Sammamish. Its neighboring cities are Bellevue to the west and Sammamish to the north. Issaquah resides within the Mountains to Sound Greenway.

According to the United States Census Bureau, the city has a total area of 11.40 square miles (29.53 km), of which 11.38 square miles (29.47 km) are land and 0.02 square miles (0.05 km) are water.

Issaquah is surrounded on three sides by what are known locally as the Issaquah Alps: Cougar Mountain on the west, Squak Mountain to the south, and Tiger Mountain to the southeast. To the north of Issaquah is Lake Sammamish. Cougar and Squak Mountains are home to sizable neighborhoods on their lower slopes, though the bulk of all three mountains are preserved in public ownership as Squak Mountain State Park, Cougar Mountain Regional Wildland Park, West Tiger Mountain NRCA, and Tiger Mountain State Forest. Geologists have noted the chemical and geological content of these three mountains to be much different from that of the Cascade Range, because they are not volcanic in origin, while the entire Cascade Range is postulated to have formed from volcanic action. They believe that these three mountains are the remains of a much older mountain range long since eroded by earthquakes, volcanic action, and shifting plates.

Climate

Issaquah has a warm-summer Mediterranean climate (Köppen: Csb) with chilly, extremely wet winters and warm, moderately humid summers. Although there is no dry season in Issaquah, winters are many times wetter than the summers.
