SEATTLE (AP) — The Army Corps of Engineers said Thursday that hurried repairs this summer at the Howard Hanson Dam have lessened the chances the Green River will flood this winter to 1-in-25.
Previously, the corps has said there was a 1-in-4 chance that a flood would inundate the heavily developed Green River Valley downstream. The corps has been working around the clock to prevent flooding, pumping tons of grout into the problem area, an abutment at the dam that was badly weakened by a torrential storm last winter.
Residents, businesses and local governments in the long, flat valley south of Seattle have been working feverishly to fortify their property and the levees along the winding river against a potentially catastrophic flood during the winter rainy season.
