The Tualatin Valley is a farming and suburban region southwest of Portland, Oregon in the United States. The valley is formed by the meandering Tualatin River, a tributary of the Willamette River at the northwest corner of the Willamette Valley, east of the Northern Oregon Coast Range. Most of the valley is located within Washington County, separated from Portland by the Tualatin Mountains. Communities in the Tualatin Valley include Banks, Forest Grove, Cornelius, Hillsboro, Aloha, Beaverton, Sherwood, Tigard, and Tualatin.

The Tualatin Plains are a prairie area in central Washington County, Oregon, United States. Located around the Hillsboro and Forest Grove areas, the plains were first inhabited by the Atfalati band of the Kalapuya group of Native Americans. Euro-American settlement began in the 1840s.

Dairy Creek is a 10.55-mile (16.98 km) tributary of the Tualatin River in the U.S. state of Oregon. It begins at the confluence of its east and west forks near the unincorporated community of Schefflin and meanders southeast across the Tualatin Valley to the Tualatin River near Hillsboro, in Washington County. East Fork Dairy Creek begins at 45.788446°N 123.041498°W / 45.788446; -123.041498 (Dairy Creek East Fork source) in Columbia County, slightly north of its border with Washington County, and flows generally south for 22 miles (35 km). West Fork Dairy Creek, also about 22 miles (35 km) long, forms at 45.7553899°N 123.178168°W / 45.7553899; -123.178168 (Dairy Creek West Fork source), near the unincorporated community of Tophill, and flows generally southeast. Before railroads displaced river boats on the Tualatin, some steamships also worked the lower section of Dairy Creek, with plans to go as far up stream as Centerville.

Area code 575 is a telephone area code in the North American Numbering Plan (NANP) for the U.S. state of New Mexico. The numbering plan area (NPA) comprises the remainder of the state outside the Albuquerque, Santa Fe, Farmington, and Gallup metropolitan and micropolitan areas, which use area code 505. Operation of area code 575 became effective on October 7, 2007, splitting from NPA 505. Area code 505 is one of the original area codes established with the North American Numbering Plan in 1947, when it served the entire state. Since October 2007, it has been the last area code in the United States introduced by an area code split, and will likely be the last area created from such. All new area codes added in the U.S. since have been from overlays, in which a new code is added to the same geographic area as an existing code. Prior to October 2021, area code 575 had telephone numbers assigned for the central office code 988. In 2020, 988 was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which created a conflict for exchanges that permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021.

Area codes 503 and 971 are telephone area codes in the North American Numbering Plan (NANP) for the northwestern region of the U.S. state of Oregon. The numbering plan area (NPA) comprises the cities of Portland, Salem, and Astoria. Area code 503 was one of the original North American area codes of 1947, assigned to the entire state until 1995, when its extent was reduced to the northwest corner. Area code 971 was assigned to the service area in stages, completed in 2008, to form an overlay in the area with ten-digit dialing.

North American area code 505 is a New Mexico telephone area code which was one of the original area codes established in October 1947. Until October 7, 2007, it covered the entire state of New Mexico. It serves the northwestern and central portions of the state, including the Albuquerque metropolitan area, Gallup, Santa Fe, and Farmington. Due to the increasing demand for new numbers, area code 505 was split on October 7, 2007. Northwestern and central New Mexico continued to be served by the 505 area code, while the remainder of the state switched to area code 575.[1] The issue was decided in 2006 by vote of the New Mexico Public Regulation Commission, with a 3–2 majority in favor of allowing the Albuquerque area to keep the old area code.[2]The question of how to implement a new area code was a contentious one. The need for a new code had been clear since at least 2000[3], but the PRC's initial votes for Albuquerque and Santa Fe to switch to a new area code and the rest of the state to keep the old 505 area code (including the Farmington and Gallup areas that are now part of the current 505 area code) were met with vocal opposition.[4] Amid heightening tensions between the urban and rural areas of the state, the commission eventually chose to put off the decision until 2006 after number pooling made the immediate addition of a new code unnecessary.[5]Prior to October 2021, area code 505 had telephone numbers assigned for the central office code 988. In 2020, 988 was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which created a conflict for exchanges that permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021."The 505" (a reference to the area code for New Mexico) is a slang term indicating the state of New Mexico.

Hillsboro ( HILZ-burr-oh) is the fifth-largest city in the U.S. state of Oregon and is the county seat of Washington County. Situated in the Tualatin Valley on the west side of the Portland metropolitan area, the city hosts many high-technology companies, such as Intel, locally known as the Silicon Forest. At the 2020 Census, the city's population was 106,447.For thousands of years the Atfalati tribe of the Kalapuya lived in the Tualatin Valley near the later site of Hillsboro. The climate, moderated by the Pacific Ocean, helped make the region suitable for fishing, hunting, food gathering, and agriculture. Settlers founded a community here in 1842, later named after David Hill, an Oregon politician. Transportation by riverboat on the Tualatin River was part of Hillsboro's settler economy. A railroad reached the area in the early 1870s and an interurban electric railway about four decades later. These railways, as well as highways, aided the slow growth of the city to about 2,000 people by 1910 and about 5,000 by 1950, before the arrival of high-tech companies in the 1980s. Hillsboro has a council–manager government consisting of a city manager and a city council headed by a mayor. In addition to high-tech industry, sectors important to Hillsboro's economy are health care, retail sales, and agriculture, including grapes and wineries. The city operates more than twenty parks and the mixed-use Hillsboro Stadium, and ten sites in the city are listed on the National Register of Historic Places (NRHP). Modes of transportation include private vehicles, public buses and light rail, and aircraft using the Hillsboro Airport. The city is home to Pacific University's Health Professions Campus. Notable residents include two Oregon governors.

The Hillsboro Civic Center is a government-built, mixed-use development in downtown Hillsboro, Oregon, United States. The development includes the city hall for the county seat of Washington County, located west of Portland, Oregon. Covering 6 acres (24,000 m2), the Civic Center has a total of over 165,000 square feet (15,300 m2) in the complex. The total of six stories for the main structure makes the building the tallest in the city, tied with Tuality Community Hospital. In addition to government offices, the Civic Center includes retail space, public plazas, and residential housing. The complex was built to centralize city government functions under one roof. Design of the complex began in 2002, with construction beginning in 2003. After completion in 2005, the building was awarded the LEED Gold certification for sustainability, the second city hall in the United States to earn that distinction. Environmentally friendly technologies used include occupancy sensors, ventilation that monitors carbon dioxide levels to determine when to activate, high performance exterior glass to reduce heat loss, and solar panels to generate electricity.
