Flood preparation for the Green River Valley Green River Valley residents of all ages fill sandbags for use around homes and businesses. Residents, businesses and farms below the Howard Hanson Dam in the Green River Valley should prepare now for a higher risk of flooding. The higher risk is due to water seeping more rapidly through an earthen bank next to the dam after record high water last winter. Until the U.S. Army Corps of Engineers (Corps) can make repairs, it must limit the amount of flood water it stores behind the dam. If heavy and prolonged rain occurs this flood season (roughly October through March), many homes and businesses in the valley that don't typically see flood water--including parts of Auburn, Kent, Renton, South Seattle and Tukwila--could be flooded. Evacuations in some communities are possible. Key transportation routes and transit service could be disrupted, and power outages and sewage back-ups are possible even outside the immediate flood zone. Frequently asked questions (PDF)Prepare now by attending a public meeting and following the action plan and help keep your family and property safe when the rains come. ¡Preparémonos ya!
