Tri-Cities, Washington

The Tri-Cities are three closely linked cities (Kennewick, Pasco, and Richland) at the confluence of the Yakima, Snake, and Columbia Rivers in the U.S. state of Washington. Located in the Columbia Basin of Eastern Washington, the cities border one another, making the Tri-Cities seem like one uninterrupted mid-sized city. The three cities function as the center of the Tri-Cities metropolitan area, which consists of Benton and Franklin counties. The Tri-Cities urban area includes the city of West Richland, the census-designated places (CDP) of West Pasco and Finley, as well as the CDP of Burbank, despite the latter being located in Walla Walla County.
The official 2023 estimate of the Tri-Cities MSA population is 314,253, a more than 24% increase from 2010. 2016 U.S. The combined population of the three principal cities themselves was 228,482 at the 2023 census. As of April 1, 2023, the Washington State Office of Financial Management, Forecasting Division estimates the cities as having a combined population of 316,600.
Tri-Cities Airport is located in Pasco and provides the region with commercial and private air service. Pasco is the seat of Franklin County, while the other two cities are located in Benton County. In 2010, Kiplinger rated the Tri-Cities among the Top 10 best places to raise a family, and CNN/Money ranked the Tri-Cities one of the top 10 best bets for gains in housing value, due to its relatively stable economic conditions since the early 2000s.
Pasco was the first of the Tri-Cities to be incorporated, in 1891. Kennewick was incorporated in 1904, and Richland followed in 1910. West Richland—a suburb of Richland, as well as the fourth largest city in the metropolitan area—was founded by dissatisfied residents of Richland, who wished to be home owners rather than renters of government-owned houses, after the arrival of Hanford. Despite attempts by Richland to annex the community, they remained separate and eventually became incorporated in 1955.
Pasco was the largest city in the Tri-Cities, mostly due to its railroad station. It also had the most land for easy irrigation and farming and was still the largest up until the founding of Hanford near Richland.
Farming was the basis of virtually every sector of the economy in the early years. Indeed, the area remained mostly rural well into the 1940s. It did not have a daily newspaper or radio station until the mid-1940s. Even today, agriculture is a big part of the Tri-Cities, Pasco in particular.
After the founding of the Hanford Site in 1943 as part of the Manhattan Project, Richland became the largest city of the three overnight. Richland's Columbia High School adopted "Bombers" as its mascot (complete with mushroom cloud logo). In 1970, Kamiakin High School (in the neighboring city of Kennewick) was founded in response to the continued influx of people. The economy continued to grow, but not without some turbulence. Every time the Hanford facilities experienced reduced funding, thousands of people would suddenly become jobless. During this time, other employers slowly made their way into the area, but they too would often be forced to cut jobs in the bad times. Since the 1970s, Kennewick has had the greatest population of the three cities. The Columbia Center Mall opened in 1969 on land newly incorporated into Kennewick, drawing growth to western Kennewick and south Richland.
Completion of the Interstate 182 Bridge in 1984 made Pasco much more accessible, fueling the growth of that city. With the end of the Cold War, many in the area feared a shutdown of Hanford, followed by the Tri-Cities quickly becoming a ghost town. These fears were allayed after the United States Department of Energy switched the facility's purpose from the creation of nuclear weapons to the effective sealing and disposal of radioactive waste. During the 1990s, several major corporations entered the Tri-Cities, which helped to begin diversifying the economy apart from the Hanford sector. In 1995, a sixth public high school, Southridge High, was founded in south Kennewick.
The 2000s saw continued rapid growth as the Hanford site hired hundreds of workers to help with the cleanup effort. Additionally, the Tri-Cities saw a large influx of retirees from various areas of the Northwest. During this time, and the corresponding nationwide housing boom, all three cities flourished and grew significantly. Pasco became the fastest growing city in Washington (in terms of both percent increase and number of new residents). In 2005, the Census Bureau reported that Pasco's population had surpassed Richland's for the first time since pre-Hanford days. Fueled by the boom, Chiawana High School was founded, and by 2019 had become the largest high school in the entire state.
Despite the economic recession of the late 2000s, the Tri-Cities area continued to maintain steady growth and a stable economic climate due in part to the American Recovery and Reinvestment Act of 2009 which directed funding and jobs to the Hanford site and its various cleanup efforts.
The Tri-Cities are in a semi-arid climate, receiving an average of 5 to 7 inches (130 to 180 mm) of precipitation every year. Winds periodically exceed 30 mph (48 km/h) when Chinook wind conditions exist. While there are an average 225 clear days every year, these are mainly between April 1 and November 1. Temperatures range from as low as −10 °F (−23 °C) in the winter (record low −29 °F (−34 °C) in December 1919) to as high as 110 °F (43 °C) in the summer, and Richland reached 118 °F (48 °C) during the 2021 Western North America heat wave. The region receives a yearly average of seven inches of snow but has received as much as 50 inches. Due to the semi-arid climate and subsequent large amounts of sand, a perpetual annoyance to residents is the amount of dust blown about by the frequent winds. Thanks to the aforementioned rivers, a large amount of cheap irrigation is available.
Washington is the most northwest of the lower 48 states—consequently, the area is in the Pacific Standard Time Zone. The Tri-Cities makes up the largest metropolitan area in the southeastern quadrant of Washington. The large Cascade Mountain Range to the west contributes to the semi-arid climate, which is far drier than the famously wet western side of the state. See rain shadow for more information on this phenomenon. The region's climate results in a shrub-steppe ecosystem which has 18 endemic plant species. Just west of Richland, the Fitzner/Eberhardt Arid Lands Ecology Reserve was established to study the unique plants and animals found in the local shrub steppe ecosystem. It is the largest tract of shrub-steppe ecosystem remaining in the U.S. state of Washington.
Limited city lights and an absence of photopollution in the Tri-Cities area allow for naked-eye and telescopic astronomy. The Tri-City Astronomy Club partners holds star gazing events at the Hanford Observatory. Hiking locations, such as Badger Mountain, Candy Mountain and Jump Off Joe Butte, provide views of sunrises and sunsets, studies of celestial bodies and stellar astronomy. The aurora borealis (or northern lights) is sometimes visible near Tri-Cities at specific times of the year.
Higher education institutions in the Tri-Cities area include:
In 2005, the State of Washington approved the transition of the existing Washington State University branch campus in Richland from a two-year to a four-year campus. In the fall of 2007 the campus admitted its first undergraduate students. Offering a range of programs, the campus focuses on biotechnology, computer science, and engineering, due to the nearby Pacific Northwest National Laboratory and Hanford Site. The university also offers a range of majors, including English, history, and other liberal arts and sciences.
Columbia Basin College also offers higher education courses for residents of the Tri-Cities, as well as the Columbia Basin from Mattawa, Washington, which is 50 miles (80 km) away, to Umatilla, Oregon, 30 miles (48 km) away.
Each city provides its own schooling services through their respective school districts—Kennewick's, Pasco's, and Richland's.
Public high schools in the Kennewick School District include Kennewick High School, Kamiakin High School, Southridge High School. Public high schools in the Pasco School District are Pasco High School, Chiawana High School, and New Horizons High School. In the Richland School District, public high schools include Richland High School, Hanford High School, and River's Edge High School.
The area also contains two regional high schools, Tri-Tech and Delta High. Tri-Tech is a technical/vocational high school in the Kennewick School District that is attended by students from all over the Tri-Cities area. Delta High is a science and technology focused high school located in Pasco. It is sponsored by Pasco, Kennewick, and Richland's school districts, Battelle, Washington State University Tri-Cities, and Columbia Basin College.
There are also several private and faith-based schools in the area, including Tri-Cities Prep Highschool (Pasco), Kingspoint Christian School K–12 (Pasco), Tri-Cities Adventist School (Pasco), Liberty Christian School (Richland), Bethlehem Lutheran K–8 (Kennewick), and Calvary Christian School K–8 (Kennewick).
In the 1940s, the Hanford site employed a majority of residents. The United States government built a top-secret facility to produce and separate plutonium for nuclear weapons, and decided on an area just north of then-tiny Richland. The government built temporary quarters for the more than 45,000 workers and built permanent homes and infrastructure for other personnel in Richland. The city had an overnight population explosion, yet virtually no one knew what the purpose of Hanford was until the destruction of Nagasaki on August 9, 1945, by an atomic weapon containing Hanford-produced plutonium. After World War II Hanford continued work on creating material for nuclear weapons during the Cold War. After the fall of the USSR in 1991, Hanford, the site of severe nuclear contamination, changed its mission from plutonium production to environmental cleanup and restoration.
The Hanford site is one of the largest cleanup projects in the United States, costing over $1.4 million per day to turn over 53 million US gallons (200 Ml) of nuclear waste into glass through a process called vitrification. Vitrification is a proven technique in the disposal and long-term storage of nuclear waste or other hazardous wastes. Original estimates were $2.8 billion over five years to clean up the waste, though estimates quickly grew in the early 1990s to $50 billion with a completion date of 30 years. As of 2021, the additional cost to complete cleanup is now projected to be between $300 and $640 billion with an estimated completion date of 2078. Over 18 percent of all jobs in the Benton Franklin County area are nuclear-related, research-related, or engineering.
The Columbia Generating Station operates ten miles outside of Richland and is the only nuclear power station in the Pacific Northwest. It uses a boiling water reactor with a type 5 layout and was relicensed 10 years to operate until 2043. After nine years of construction, the plant began operating after a long and costly construction process that resulted in the largest municipal bond default in U.S. history. Originally operated and owned by the Washington Public Power Supply System (WPPSS), the coalition changed its name to Energy Northwest in 1998 because of the negative association with the original name (commonly pronounced "Whoops" in place of WPPSS). WPPSS defaulted on $2.25 billion in bonds resulting in payments that exceeded $12,000 per customer, an amount which was finally paid out in 1992 (10 years later). Its 1,190 gross megawatts can power the city of Seattle, and is equivalent to about 10 percent of the electricity generated in Washington and 4 percent of all electricity used in the Pacific Northwest and has several safeguards to protect against seismic, natural, or terrorist threats.
The Tri-Cities economy has historically been based on farming and the Hanford Nuclear Reservation. From Pasco's incorporation in 1891 to present day, the Tri-Cities have had a large degree of farming thanks to irrigation by the three nearby rivers. Wheat is the most commonly grown product; however, large amounts of apples, corn, grapes are also grown, along with potatoes, and other products including asparagus. Cherries are also grown in the region.
Grapes grown in the region are essential to the wine industry. Wineries draw a large population of tourists. With 160 wineries in the Columbia Valley, this industry accounts for $1 billion annually in Benton County alone.
The Tri-Cities' climate allows the region to have a broad and sustainable agricultural economy. Local industries provide employment for thousands of people in the Tri-Cities area. Some of the top 20 employers in agriculture include ConAgra, Tyson Foods, and Broetje Orchards. Agriculture makes up 9.5% of employment in Tri-Cities and local businesses combined employ thousands of people. In 2012, the state of Washington was rated No. 1 in the nation when it comes to growing apples, hops, spearmint oil, sweet cherries, pears, concord grapes and processing carrots. The Mid-Columbia region including the Tri-Cities grows most of these crops. The region's climate and irrigation from nearby rivers, like the Columbia, Snake, and Yakima rivers, allow farmers to produce corn, hay, wheat and potatoes. In Washington there are 39,500 farms; 1,630 of these farms are located in Benton County and 891 are located in Franklin County.
The Tri-Cities has a number of locally owned and operated restaurants. The Spudnut Shop, for example, located in northern Richland, was opened in 1948 and has been family-run ever since. The Travel Channel featured The Spudnut Shop and their donuts "made from potato flour and then deep-fried to perfection." Carmine's, also a family owned restaurant in the region, served Italian food in a historic home that was constructed in downtown Kennewick in 1929. The owners retired in 2021, closing the restaurant after celebrating their 59th wedding anniversary. Also notable is the BBQ restaurant Porter's which began as a food truck in Richland and has been featured on Diners, Drive-Ins and Dives hosted by Guy Fieri.
In contrast to Seattle, the western slopes of the Cascade Mountains, and the rain forests of the Olympic Peninsula, the Columbia Valley enjoys long, warm, summer days, and crisp cool nights. The dry weather combined with rich volcanic soils and controlled irrigation produce near-perfect conditions for the cultivation of wine grapes.
The range of varietals grown throughout the region include Chardonnay, Cabernet Sauvignon, Merlot, Riesling, and Pinot Noir.
The Tri-Cities region has a rich winery culture that attract tourists and visitors to the area. Some of the local microbreweries include: Ice Harbor Brewery Company, Atomic Ale Brewpub and Eatery, and White Bluff Brewing. This brewery was founded in 1996 and has two locations in the Tri-Cities metropolitan area, one in downtown Kennewick and one on Clover Island. In 2010, Ice Harbor received a bronze award for their Sternwheeler Stout, Runaway Red Ale, Indian Pale Ale (IPA) and a Silver Award for their Tangerine "ExBEERience" Hefeweizen at the Washington Beer Awards competition. Another micro-brewery, the Atomic Ale Brew Pub & Eatery, is located in Richland and serves as Tri-Cities oldest brewpub and was opened in 1997.
The Market at the Parkway in Richland, WA is a farmers market with takes place every Friday from June through October. Local artists provide music and crafts, and Fresh produce, specialty foods, arts and crafts are sold at the Richland farmers market.

Amtrak provides connection to the daily Empire Builder serving Portland and Chicago.
Due to the dry climate, hot summers, and mild winters, the Tri-Cities offers a variety of outdoor activities.
The area is home to 10 golf courses which can be played nearly year-round. These include Canyon Lakes, Columbia Park, and Zintel Creek Golf Clubs in Kennewick; Sun Willows Golf Club and Pasco Golfland in Pasco; and Columbia Point, Horn Rapids, West Richland, Meadow Springs, and Buckskin Golf clubs in Richland.
The Tri-Cities metropolitan area has a number of outdoor trail running locations. A number of competitive running events are held throughout the year, including a number which are sponsored by the Three Rivers Road Runners Club (3RRR). They include:
The Tri-Cities is linked by a system of 67 miles (108 km) of paved pedestrian and bike trails that run through the various cities and along the rivers. The 23-mile (37 km) Sacagawea Heritage Trail forms a loop that crosses two bridges and runs along the Columbia River through both Kennewick and Pasco. Sacagawea Heritage Trail also connects with the Richland Riverfront Trail, a marked hiking trail that focuses on the state of Washington's contribution to the nuclear history of the United States.
The confluence of the Snake, Yakima, and Columbia rivers provides ample opportunity for boating, fishing, and swimming. Free boat launches can be found throughout all of the cities.
The Tri-Cities is home to seven river-front parks and various other parks and playgrounds. Three skate parks are located in the area; two in Kennewick and one in Richland.
Highlands Grange Park is a Kennewick city owned Public Park between 14th and 19th streets off of Union in Kennewick. This park covers 26 acres (11 ha), serving the surrounding new and old communities of approximately 13,000 citizens.
According to the City of Kennewick Comprehensive Parks and Recreation Plan 2013–2018, this park requires 6 acres (2.4 ha) of expansion due to the larger than expected community growth of the area. The Southridge Sports and Events Complex helps provide park service for the adjacent Grange neighborhoods.
This park features plenty of recreation, including a playground structure, basketball courts, a soccer/softball field, tennis courts, a roller hockey rink, a water feature, and 8/10-mile walk through a demonstration garden. Additionally, there are two picnic shelters for hosting public events and 79 parking spaces (not including the neighboring Kennewick branch of Mid-Columbia Libraries).
The park's most notable features include the demonstration garden and the water feature. The water feature provides summertime entertainment for local children inviting them to play amidst the colorful metal palm trees that shower water. The demonstration garden is Highland Grange Park's primary attraction and community draw, representing a visual festival of roses and other flowers tended to by master gardeners from Washington State University. This park is commonly used for public events, ranging from weddings in the demonstration garden to weekend BBQs under the picnic shelters. The park also touts the adjacent Highlands Grande building available for reservations and indoor events.
Tri-Cities has three skate parks: two in Kennewick and one situated in Richland. Jeanette Taylor Park, is the number three ranked stated skate-park in Washington. Completed in 2005, this 22,100-square-foot (2,050 m) park features street elements, an 8-foot (2.4 m) bowl off of a snake run, and a half-pipe/bowl that is 10 feet (3.0 m) deep. The Jeanette Taylor skate park hosts a number of contests and events.

The Tri-Cities is home to one minor league baseball team, the Tri-City Dust Devils of the Northwest League, and one major junior hockey club, the Tri-City Americans of the Western Hockey League.
The first of these teams to join the Tri-City area was the Tri-City Americans. The franchise relocated to the Tri-Cities initially as the New Westminster Bruins and later changed its name to the "Americans" in 1988. The Americans have advanced to the WHL finals one time in their tenure in the Tri-Cities, where they lost to the Calgary Hitmen 4–1 during the 2009–10 season. The Americans currently play at the Toyota Center in Kennewick, Washington.
The Tri-City Dust Devils are a High-A minor league baseball team that is an affiliate of the Los Angeles Angels. The Dust Devils came to the Tri-Cities in 2001, relocating from Portland as a member of the short-season Northwest League and changing the team's name from the Portland Rockies to the Tri-City Dust Devils. The Dust Devils took over as the primary tenants of Gesa Stadium, which previously housed the Tri-City Posse. The Dust Devils were Northwest League East Division Champions three times, in 2007, 2009 and 2011, all as a Colorado Rockies affiliate. In the 2021 Minor League Baseball realignment, the Dust Devils were elevated along with most of the former Northwest League to full-season High-A baseball under the new High-A West league name, and were assigned affiliation with the Angels.
From 2005 to 2016, there was also professional indoor football team called the Tri-Cities Fever. The team came to the Tri-Cities in 2005 as an expansion team for the National Indoor Football League. Since then, the Fever switched to the AF2 in 2007, and then to the Indoor Football League in 2009. The Fever, housed in the Toyota Center in Kennewick, have won one division title and one league championship. The Fever won the Indoor Bowl in 2005 as a member of the NIFL, and in 2012 they were the Intense Division champions in the IFL where they ultimately lost the United Bowl Championship game to the Sioux Falls Storm.

Stations and networks which serve this market include KFFX-TV (a Fox affiliate), KVVK (a Univision affiliate), KEPR (a CBS affiliate), KNDU (NBC), KTNW (PBS), and KVEW (ABC). All except KFFX and KTNW are satellites of Yakima stations. KFFX is a full-fledged station, while KTNW repeats KWSU-TV in Pullman

Over the years, a number of proposals have been made to consolidate the cities into a united incorporated area. The idea behind this movement, which would make the resulting incorporated area the fourth largest city in the state, is that one larger city would create the presence needed to draw increased attention and focus to the region. Several motions to consolidate have not been passed.
Proposed names for such a consolidated area have included the "Quad-Cities" (accounting for West Richland), "Tri-Cities", or "Three Rivers". West Richland has separately been proposed to be renamed to "Red Mountain", in an attempt to distinguish itself from Richland.
