Hillsboro, with an estimated population of 84,445, is the most populated city in Washington County and the fifth largest in Oregon. However, a much larger daytime population of approximately 110,000 has been recorded due to people commuting into the city for work. Founded by David Hill in the 1840's and incorporated in 1876, the city began as an agricultural center, but in the recent three decades has grown to be a center for computer and bio-technology companies. The companies who make up the self-named Oregon's Silicon Forest include Intell, Sun Microsystems, Yahoo, Credence Systems, Synopsys, Epson, TriQuint Semiconductor, Corillian Corporation, Lattice Semiconductor, RadiSys, and Planar System. Other companies that have factories in the area are Fujitsu and NEC.
Hillsboro, located in the Tualatin Valley, is a great outdoor sports destination due to the close proximity of several water features like the Dairy, McKay, Rock, Dawson, and Turner Creeks. The Tualatin River forms parts of the southern city limits. Hillsboro's Department of Parks and Recreation operate over 20 facilities including Hillsboro Stadium. There are 21 parks, 2 sports complexes, the Walters Cultural Arts Center, the Shute Park Aquatic and Recreation Center, and 3 other mixed-use facilities. Other area parks include the Jackson Bottom Wetlands Preserve and the Bald Peak State Scenic Viewpoint. The city has also earned the distinction of being the "Best Planned Community" in 1999 by the National Association of Home Builders and "Best New Burb" by Sunset Magazine in 2006.
Colleges and universities that call the city home are the west campus of Oregon Health and Science University, the Oregon Graduate Institute, the Oregon National Primate Research Center portions of OHSU, and a satellite campus of Pacific University. Performing arts in the area can be enjoyed through venues like the Hillsboro Repertory Theatre, and presentations by the Oregon Chorale and Hillsboro Symphony Orchestra. If cruising through beautiful countrysides and sampling local wineries is your cup of tea, you enjoy locations like the Gypsy Valley Winery, Helvetia Winery & Vineyards, Oak Knoll Winery, and the Lion Valley Winery. Area events include The Oregon International Airshow and the annual 4th of July Parade, the largest in the state of Oregon.
