Tukwila flooding almost inevitable,
After last winter's record high waters on the Green River last winter, the risk of flooding in Tukwila and other valley cities this winter is greatly increased and almost inevitable.
A depression in the right abutment of the Howard Hanson Dam was recently discovered. The US Army Corps of Engineers, as a result, will be lessening the amount of water in the flood storage pool that the dam holds. This will raise the water level in the Green River Valley below the dam.
Tukwila's residents and commercial properties are at high risk this flood season, (which is roughly from October to March.) The potential flood risk areas run roughly from the Segale Business Park, through Southcenter, Interurban Avenue, and all the way to East Marginal Way.
King County Councilwoman Julia Patterson is chair of the King County Flood Control District.
Patterson says "the higher risk of flooding in Tukwila is due to the water seeping more rapidly through an earthen bank next to the Howard Hanson Dam after record high water last winter."
She says home owners who do not normally experience flood problems may find themselves in several feet of water.
