Yakima River Flooding: West Richland, Benton City and Prosser
Flood stages at Kiona, flood insurance, and cleaning up after river water.
WEST RICHLAND · WA
Just west of Richland, on the lower Yakima River.
West Richland has two kinds of water damage: the everyday kind (frozen pipes, failed water heaters, appliance leaks) and river flooding on the low ground along the Yakima. River water is treated as contaminated, so those jobs involve removing soaked materials and disinfecting, not only drying.
West Richland sits beside the lower Yakima River, and much of it is newer housing on larger lots with open land between neighborhoods. When warm rain falls on mountain snow upstream, the river can rise quickly. The Kiona gauge's flood stage is 13 feet, the February 1996 flood reached about 21, and recent high water closed Van Giesen Street into town. Away from the river, the problems look like the rest of the Tri-Cities: pipes in cold spaces, aging tanks and appliance hoses.

River water and pipe water get handled differently, and the difference matters for both the cleanup and the insurance claim. Describe the source when you ring.
Many West Richland homes have attached shops or outbuildings and long water lines between them, which means more pipe exposed to winter cold and more places for a leak to start out of sight. On low ground near the Yakima, floodwater brings silt and contamination; porous materials it touched usually come out, and the rest is cleaned before drying. Flood damage needs a separate flood policy, so it's worth checking coverage before the high-water season.
Close the main valve, stay clear of outlets near the water, move what you can to a dry room and take photos for the insurer.
