About the Soundside Alliance

The Soundside Alliance for Economic Development is a partnership of five Seattle area cities (Burien, Des Moines, Normandy Park, SeaTac, and Tukwila), the Port of Seattle, Highline College, and the Seattle Southside Chamber of Commerce. As a collective, we believe Southwest King County exists as a singular destination for businesses of all shapes and sizes, for economic growth, and for prosperity.
