Frequently asked questions

Kennewick, WA

Kennewick is a city in Benton County in the U.S. state of Washington. It is located along the southwest bank of the Columbia River, just southeast of the confluence of the Columbia and Yakima Rivers and across from the confluence of the Columbia and Snake Rivers. It is the most populous of the three cities collectively referred to as the Tri-Cities (the others being Pasco and Richland). The United States Census Bureau estimated the population to be 84,750 as of 2022, up from 83,921 at the 2020 United States Census.

The discovery of Kennewick Man along the banks of the Columbia River provides evidence of Native Americans' settlement of the area for at least 9,000 years. American settlers began moving into the region in the late 19th century as transportation infrastructure was built to connect Kennewick to other settlements along the Columbia River. The construction of the Hanford Site at Richland accelerated the city's growth in the 1940s as workers from around the country came to participate in the Manhattan Project. While Hanford and Pacific Northwest National Laboratory continue to be major sources of employment, the city's economy has diversified over time, and Kennewick today hosts offices for Amazon and Lamb Weston.

Kennewick is located in Eastern Washington along the south side of the Columbia River and is one of three cities in the Tri-Cities. The other two cities are Richland, which is upstream of Kennewick on the same side of the river, and Pasco, which is across the river. The elevation within the city rises from the river to a line of ridges on the south side of town that are a result of the same anticline that created Badger Mountain and Rattlesnake Mountain. Beyond that line of ridges, the city slopes up toward the Horse Heaven Hills. According to the United States Census Bureau, the city has a total area of 28.36 square miles (73.45 km²), of which, 26.93 square miles (69.75 km²) is land and 1.43 square miles (3.70 km²) is water. The former community of Vista is now a neighborhood fully contained within Kennewick.

The city overlies basalt laid down by the Columbia River Basalt Group, which was a type of volcanic eruption known as flood basalt. This erupted from fissures that were geographically spread throughout eastern Washington, eastern Oregon, and far western Idaho. Most of the lava erupted between 17 and 14 million years ago, with smaller eruptions lasting as late as 6 million years ago. The nearest eruptive vent to Kennewick from this period is near Ice Harbor Dam along the Snake River upstream of Burbank and Pasco. While outcroppings from the basalt flows can be seen throughout Kennewick, they are mostly buried by sediments.

The first major sediment deposit following the eruptions is the Ringold Formation, which was placed by the Columbia River between 8 and 3 million years ago. Further deposition came as a result of the Missoula Floods. At the end of the last glacial maximum, an ice dam blocked the Clark Fork River in Montana. The pressure from the resulting lake would periodically build to the point that the dam would fail, sending massive amounts of water cascading to the Pacific Ocean. The flood's movement was impeded by the Horse Heaven Hills, creating a temporary lake known as Lake Lewis. This abrupt halt in flow allowed the floodwater to drop a significant amount of sediment before passing through Wallula Gap toward Hermiston. During the largest floods, the water's surface reached 1,250 feet (380 m) above sea level. This completely covered all of the land within Kennewick's city limits.

Earthquakes are a hazard in Kennewick, though not to the same extent or frequency as areas west of the Cascade Range like the Puget Sound Region. The entire Pacific Northwest is threatened with subduction zone earthquakes that can exceed magnitudes of 9 on the moment magnitude scale. The last of these earthquakes, which could be compared to the 2011 Tōhoku earthquake in Japan, occurred in 1700. Should the next earthquake occur, damage is expected to be minimal in and around Kennewick, but destruction west of the Cascades could have a major impact on the economy of inland areas. These subduction zone earthquakes will be centered on the boundary between the North American Plate and the Juan de Fuca Plate, which is located offshore. Fault lines closer to Kennewick also produce earthquakes. While these are weaker, they can still cause damage. One such earthquake, named the 1936 State Line earthquake, occurred near Walla Walla with damage extending as far away as Prosser.
