Kennewick and the surrounding Tri-Cities area are defined by the convergence of major waterways and a complex network of irrigation infrastructure. This 2020 record shows the Columbia River widening into Lake Wallula, with Bateman Island and Wade Island punctuating the channel. The landscape is heavily marked by the region's agricultural and civil engineering heritage, featuring the Highland-Feeder Canal, A P Canal, and Division Four Canal that support the arid interior. Residential expansion is visible in West Highlands and South Highlands, while the historic core of Pasco and Richland maintain their industrial and transport links. Local history is anchored by sites like Desert Lawn Memorial Park and the deep cuts of Amon Canyon and Zintel Canyon, which provide natural relief to the dense grid of the urban centers.
