Hillsboro is a city in Oregon, a state in the United States. It is the main city of Washington County. Hillsboro is located in the Tualatin Valley, west of the Portland metropolitan area. Many high-tech companies, like Intel, are located here. This area is often called the Silicon Forest. In 2020, about 106,447 people lived in Hillsboro. This makes it the fifth-largest city in Oregon.

The city was started by settlers in 1842. It was later named after David Hill, an important person in Oregon's early days. In the past, people used riverboats on the Tualatin River to travel and trade. Later, railroads arrived in the 1870s, and electric trains came about 40 years after that. These transportation links helped the city grow slowly. By 1950, about 5,000 people lived there. Then, in the 1980s, many high-tech companies moved in, and the city grew much faster.

Hillsboro has a special type of government called a council–manager government. This means a city manager handles daily tasks, and a city council, led by a mayor, makes big decisions. Besides technology, important parts of Hillsboro's economy include healthcare, stores, and farming, especially grapes and wineries. The city has over twenty parks and a large stadium called Hillsboro Stadium. Ten places in Hillsboro are listed on the National Register of Historic Places. You can get around by car, public bus, light rail, or by flying from the Hillsboro Airport. Pacific University also has a campus in Hillsboro for health professions.

History of Hillsboro

Early Settlement and Naming

The first European-American settlers, David Hill, Isaiah Kelsey, and Richard Williams, arrived in the Tualatin Valley in 1841. More pioneers joined them in 1842. The area was first called East Tualatin Plains or Columbia. In February 1850, it was named "Hillsborough" to honor David Hill. He sold some of his land to the county for the town.

On February 5, 1850, the area was chosen to be the county seat. David Hill was supposed to get $200 for his land, but he passed away before that. His wife, Lucinda, received the money instead. Later, the town's name was made simpler to Hillsboro. The first school was a log cabin built in 1853 and opened in October 1854. Riverboats started offering transportation to Hillsboro as early as 1867.

Growth and Government Changes

In 1871, the Oregon and California Railroad line reached the area. Hillsboro officially became a town on October 19, 1876. The first mayor was A. Luelling, who started his job on December 8, 1876. Important mayors later included Congressman Thomas H. Tongue. In 1923, the city changed its government to a council-manager system. This meant a city manager would run daily tasks, while the city council and mayor would make big decisions.

On September 30, 1908, a new electric rail line, the Oregon Electric Railway, connected Hillsboro to Portland. This was the first electric train to reach the city. Another electric train service, the Red Electric, started in 1914 but stopped in 1929. The Oregon Electric Railway's passenger service to Hillsboro ended in 1932.

City Services and Modern Era

Hillsboro built its first brick building for the county government in 1852. A new courthouse was built in 1928. The city's first fire department started in 1880. In 1892–93, Hillsboro got drinking water and electricity. The first sewer system was built in 1911, and a water system in 1913. The first public library, the Carnegie City Library, opened in December 1914.

In 1979, Intel opened its first facility nearby. This was followed by other Intel campuses in Hillsboro, making it a major tech hub. In 1998, the MAX light rail line opened, connecting Hillsboro to the wider Portland area. A cultural center was added in 2004, and a new city hall in 2005. In 2011, U.S. President Barack Obama visited Intel's campus in Hillsboro.

Geography of Hillsboro

Hillsboro covers about 21.6 square miles (56 square kilometers). The city is in the Tualatin Valley, and the Tualatin River forms part of its southern border. The land in Hillsboro is mostly flat, which was good for farming in the past. Hillsboro is about 17 miles (27 km) west of Portland. It is also just west of Beaverton. The city is about 148 feet (45 meters) above sea level.

Besides the Tualatin River, other streams in the area include Dairy Creek and McKay Creek. Nearby towns are Aloha, Cornelius, and North Plains.

Street System

Hillsboro has its own unique street system. Most streets in Washington County use a numbering system based on downtown Portland. But Hillsboro uses a grid system centered on Main Street (east-west) and First Avenue (north-south) in downtown. Most addresses have a direction prefix like NW, NE, SW, or SE. Even numbers are on the south side of streets and east side of avenues. Odd numbers are on the opposite sides.

North-south roads are called avenues, and east-west roads are called streets. Short, dead-end roads are called courts. Private roads are ways or places. Roads that curve are drives, and alleys are lanes.
