Pasco (/ˈpæskoʊ/PAS-koh) is a city in and thecounty seat ofFranklin County, Washington, United States.[7] The population was 77,108 at the2020 census,[5] and estimated at 81,724 in 2024.[6]Pasco is one of three cities (the others beingKennewick andRichland) that make up Washington state'sTri-Cities region, a mid-sized metropolitan area of approximately 303,622 people.
On October 16, 1805, theLewis and Clark Expedition camped in the Pasco area, at a site now commemorated bySacajawea State Park. The area was frequented byfur trappers and gold traders. In the 1880s, theNorthern Pacific Railway was built near theColumbia River, bringing many settlers to the area. Pasco was officially incorporated on September 3, 1891. It was named byVirgil Bogue, a construction engineer for the Northern Pacific Railway afterCerro de Pasco,[8] a city in the PeruvianAndes, where he had helped build a railroad. In its early years Pasco was a small railroad town, but the completion of theGrand Coulee Dam in 1941 brought irrigation and agriculture to the area.
Due largely to the presence of theHanford Site (which made the plutonium for the "Fat Man" nuclear bomb used on Nagasaki in 1945), the entire Tri-Cities area grew rapidly from the 1940s through 1950s. However, most of the population influx resided inRichland andKennewick, as Pasco remained primarily driven by the agricultural industry, and to a lesser degree the NP Pasco rail yards. After the end of World War II, the entire region went through several "boom" and "bust" periods, cycling approximately every 10 years and heavily based on available government funding for Hanford-related work. Farming continues to be the economic driver for most of the city's industrial tax base.
Pasco was not asundown town in the same way as Richland and Kennewick, howeverJim Crow laws restrictedAfrican Americans to living only on the east side of the railroad tracks, which was largely underdeveloped without public water or garbage service. In the 1940s,Edward R. Dudley visited as an investigator from theNAACP and observed widespread discrimination from businesses and law enforcement. In a 1947 survey, black residents listed water supply and service as the most significant problem for the area, and racial discrimination as second. White residents listed over-crowded schools as the most significant problem, and the presence of blacks as second. In 1948,Hazel Scott was refused service at a Pasco restaurant and successfully sued the owners for discrimination, bringing national attention toracial segregation practices in the Tri-Cities.[9]
Pasco completed one of its largest annexations, comprising 7.5 square miles (19 km2) to the northwest, in August 1982 amid a legal dispute with neighboring Richland that was decided by theWashington Supreme Court.[10] In the late 1990s, foreseeing another Hanford-related boom period, several developers purchased large farm circles in Pasco for residential and commercial development. Since that time, Pasco has undergone a transformation that has not only seen its population overtake the neighboring city of Richland, but also has resulted in growth in the city's retail and tourism industries. Recently incorporated land on the West side of the city has exploded into new housing tracts, apartments, and shopping centers. This area of the city has become referred to locally as "West Pasco", distinguishing it from the older area of town to the East. In addition to an influx of new residents to the region, many residents of the Tri-Cities have moved from Richland and Kennewick to West Pasco due to its central location and virtually all-new housing and business. In early 2018, plans were announced for 5,000 to 8,000 new residences in West Pasco, west of Road 100.[11]
According to theUnited States Census Bureau, the city has a total area of 34.08 square miles (88.27 km2), of which 30.50 square miles (78.99 km2) is land and 3.58 square miles (9.27 km2) is water.[12]
As Pasco is located in Southeastern Washington, the city lies in therain shadow of theCascade Range. As a result, the area is a windswept desert, receiving little precipitation throughout the year. Hot summers, warm springs, and cold winters provide a stark contrast to other areas of the state. Climate data is sparse, as there is no functioning weather station in the city; more reliable data is provided by the weather station in nearbyWalla Walla.
TheColumbia River borders the south side of the city, separating it from the neighboring cities of Richland and Kennewick.
