Issaquah (/ˈɪsəkwɑː/ US dict: ĭs′·ə·kwâ) is a city in King County, Washington, United States. The population was 30,434 at the 2010 census.

According to the Washington State Office of Financial Management, Issaquah ranked 6th of 279 eligible incorporated communities in population growth between 2000 and 2005.[6] ranked Issaquah the 2nd fastest-growing suburb in the state, and the 89th in the nation.[7]


Coal miners' homes in Issaquah, 1913.

"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.[8][9]

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.

Other Issaquah employers include Siemens Medical Solutions' Ultrasound Group, GoldSim Technology Group, Overtime Technologies, Boehm's Candies, and Darigold.


Issaquah is located 15 miles (24 km) east-southeast of Seattle at the south end of Lake Sammamish. Neighboring cities include Bellevue, and Redmond, both 8 miles (13 km) away. 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 km2), of which, 11.38 square miles (29.47 km2) is land and 0.02 square miles (0.05 km2) is water.[2]

Issaquah is surrounded on three sides by the Issaquah Alps: Cougar Mountain on the west, Squak Mountain to the south, and Tiger Mountain to the east. To the north of Issaquah is Lake Sammamish. Cougar and Squak Mountains are home to sizable neighborhoods, though the bulk of all three mountains are preserved in public ownership as Squak Mountain State Park,[10] Cougar Mountain Regional Wildland Park,[11] West Tiger Mountain NRCA,[12] and Tiger Mountain State Forest.[13] Geologists have noted the chemical and geological content of these three mountains to be much different than that of the Cascade Range, simply 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.

Highways and roads

Issaquah is bisected by Interstate 90, which runs from Seattle to Boston, and Washington State Route 900, which connects the city to neighboring Renton. There is a chronic traffic congestion problem on Front Street, which traverses the historic downtown. Proposals had been made to create a bypass, but opponents argued that this will only result in more sprawl in the area beyond downtown and thus bring in more traffic and pollution. In fact, the Issaquah City Council voted in 2008 to cancel the 15-year-running SE Bypass project. In addition, King County has no funding in its seven-year capital plan to improve Issaquah-Hobart Road, the southern terminus of the proposed bypass.

Public transportation

Bus service in Issaquah is provided by King County Metro as well as regional Sound Transit routes to Seattle and Bellevue. There are two primary park-and-rides in the city, at Issaquah Transit Center and Issaquah Highlands Park & Ride, which have a total of 1,999 parking spaces.[18][19]

Since August 1995, the city and King County Metro provided a free circulator bus (route 200) between business districts and community centers in Issaquah as a form of traffic congestion relief.[20]

As part of the expansion of Sound Transit services, a Link light rail line to Issaquah from Bellevue is proposed to begin service by 2041.[21]

Local attractions

Village Theatre's First Stage, Issaquah

The neighboring highlands are called the Issaquah Alps and feature hiking trails and outdoor activity throughout the three mountains surrounding Issaquah: Tiger Mountain, Cougar Mountain, and Squak Mountain. There are also many cultural and historical activities to be found in the town of Issaquah itself.

Issaquah Valley Trolley

Issaquah Valley Trolley car. This is an ex-Milan, Italy, interurban car and is not the trolley being used for service.

The Issaquah Valley Trolley is a project of the Issaquah Historical Society with the aim of starting a regular heritage trolley service on the remaining section of railroad track in downtown Issaquah. A trial operation took place in 2001–02, giving public rides in a trolley car borrowed from Yakima Valley Trolleys. By 2010, the Issaquah Historical Society had acquired three trolleys of its own, but the planned service had not yet begun operation, as two of the cars were narrow gauge, making them incompatible with the standard gauge rails left in Issaquah, and all three were not in operating condition. A federal transportation grant was obtained, providing funds for track evaluation and repairs, and in 2012 one of the two narrow gauge cars was sent to the Gomaco Trolley Company to be refurbished and regauged to standard gauge.[22] The overhauled trolley car, ex-Lisbon 519, returned to Issaquah in August 2012, and regular public rides began in October 2012.[23] Operation is expected to be seasonal and on weekends only.

Some proponents of the Trolley Project hope to see trolley service extended to a northern re-extension of removed track to the southern tip of Lake Sammamish. Such service would add to the charm of the historical downtown area and make it easier for visitors and residents to get around and avoid the area's notorious traffic congestion. A onetime goal had been to extend trolley service all the way to downtown Redmond by reinstalling the track along the eastern shore of Lake Sammamish that the county removed several years ago. The opening of the East Lake Sammamish Trail in March 2006 along that proposed line ended the possibility of Issaquah-Redmond service.

Village Theatre

The Village Theatre has presented live stage plays on its main stage in downtown Issaquah since 1979.[24] It is an Equity theater.[25]

Salmon Days Festival

Issaquah Salmon Days is a two-day award-winning festival held in Issaquah on the first full weekend of October every year. It is initiated by a parade, celebrates the return of the salmon to their birth waters, and praises Issaquah's history, culture, and ethnic diversity. This free festival encompasses several arts and crafts conventions, attracting many Northwest artists; these artisans feature wood, glass, jewelry, paintings, pottery and metal artworks for sale in booths spread all across the downtown and historic area. There are four stages for entertainment such as live music. Sporting events include 5 km/10 km runs (and a 3 km run for children), a fencing invitational, bike rides, and a golf tournament. Memorial Field, adjacent to the city hall, hosts a "Field of Fun" providing free entertainment for children of all ages, thanks to the many festival sponsors. Visitors are encouraged to visit the newly restored Salmon Hatchery to view the returning salmon in close detail. In 2005, the register revealed over 400,000 people attended the Salmon Days Festival.

Cougar Mountain Zoo

The Cougar Mountain Zoo is located on the north slope of Cougar Mountain, just to the west of Issaquah. This 8-acre (32,000 m2) zoo offers a glimpse at many endangered species from across the globe, including many endangered birds from around the world and small lemurs from Madagascar. The highlight of the zoo for many observers is the cougar, named Nashi. Nashi is provided enrichment on a near-daily basis, which consists of a stimulant to keep him active mentally and physically. The zoo currently specializes in eight "worlds" of animals: cougars, lemurs, cranes, reindeer, macaws, wallabies, ratites, camelids. On June 16, 2007, another world was added to the list, when the zoo welcomed its newest members, two male tiger cubs. Named Taj and Almos, they are the only Bengal tigers in Washington state. The Zoo is open for general admission Wednesday through Sunday, 9 a.m. to 5 p.m. (excluding the month of December). Each December the Zoo also offers a special Reindeer Festival, during which people may come view, and feed Santa's Reindeer, and visit the "big guy" in person.

Issaquah Salmon Hatchery

The Issaquah Salmon Hatchery was built in 1936 under the federal Works Project Administration. It is located on the Issaquah Creek within the city limits of Issaquah. The hatchery is owned and operated by the Washington State Department of Fish and Wildlife.[26] It annually raises about 4 million Chinook (King) and Coho (Silver) salmon which then migrate from the Issaquah Creek to Puget sound and on to the North Pacific. Friends of the Issaquah Salmon Hatchery (FISH) is a non-profit organization that trains volunteer guides who lead free educational tours of the hatchery and advocates retaining and improving the historic hatchery. Local elementary schools often raise small numbers of salmon eggs that are spawned in the hatchery and release them into the creeks as part of their science curriculum on the salmon life cycle. The Issaquah Salmon Hatchery is located in the cultural and geographical heart of Issaquah and is the Department of Fish and Wildlife's most visited hatchery, with an estimated 350,000 visitors a year.[27]

Gilman Village

Gilman Village is a specialty shopping center created from rescued buildings dating back to the origins of the Issaquah community. Gilman Village was founded in 1972, when developers Marvin and Ruth Mohl started saving old, unwanted farming and mining buildings, as well as pioneer homes, from around Issaquah. They moved, renovated and combined them into an attractive retail area in a park-like setting. Their goal was to create a haven for independent shops and restaurants. In saving the buildings, the intent was to honor the character and ambiance of the old community rather than to create a museum. Still, the buildings that house the shops and restaurants of Gilman Village represent a significant portion of Issaquah's history.

The 40-plus shops and restaurants that make up Gilman Village became one of Puget Sound's best known and most distinctive shopping destinations. In its initial decades, Gilman Village was a destination while Issaquah was still a somewhat rural area. Over time, Gilman Village began to compete with other local shopping centers for tenants serving the Issaquah population.[28]

Designers of Gilman Village have included the Baylis Architects, Richard Haag Associates and landscape architect Stephen G. Ray. Their combined efforts have won official recognition by the King County Board of Realtors in 1976 and the Issaquah Design Commission in 1977 for quality of design and landscaping. In 1985, The Bellevue Chamber of Commerce presented the Eastside Quality of Life Award to Gilman Village for "the pleasures it gives through its rich discoveries of space and forms."
