Hillsboro

Oregon, United States

Hillsboro, city, seat (1850) of Washington county, northwestern Oregon, U.S., adjacent to the Tualatin River. Settled in 1841, it was laid out by David Hill in 1842, called Columbia, and later renamed (by court order) for its founder. The city developed as a processing-shipping centre for wheat, truck-garden produce, and dairy products. Electronics manufacturing and specialty horticulture are the most important components of the modern economy. The city maintains the Jackson Bottom Wetlands Preserve, a 650-acre (263-hectare) wetland. Hillsboro’s Old Scotch Church (1873) remains in use; its cemetery contains the graves of several well-known pioneers. Inc. 1876. Pop.
