Initial CSI basin planning, 1999-2003

North Green River planning area

Planning was completed in the North Green River Planning area to address capacity issues related to growth in the Southcenter area of Tukwila. The principle project in this basin is to upgrade portions of the Tukwila Interceptor and Tukwila Freeway Crossing under the I-5 and I-405 freeways near Tukwila. The working alternative will initially parallel or replace portions of these two facilities, but before the project is ready for predesign, King County will assess the impacts of the Port of Seattle SeaTac airport industrial waste discharges and development proposals in Southcenter. This project will likely begin predesign in 2005.
