2017 Map of Columbia Point

About this map

The confluence of the Columbia River and the Yakima River (just off-sheet) defines the development of Pasco and Richland, as seen in this 2017 survey. The prominent Columbia Point landform reaches into Lake Wallula, a reservoir created by downstream damming that transformed this arid landscape into a major transportation and aviation hub. Urban expansion is evident in West Pasco, where residential street grids have rapidly filled the space between historic irrigation routes like Taylor Flats Rd and Selph Landing Rd. To the northeast, the dry drainage of Esquatzel Coulee cuts through the high desert terrain, contrasting with the dense infrastructure surrounding the Tri-Cities Airport. The map also clearly delineates the border between Benton and Franklin counties as it follows the river's center.
