Sewage spill closes two Pierce County parks' beach access News Tribune, Tacoma, Wash. 16 hrs ago Abby Miller, The News Tribune (Tacoma, Wash.) Jul. 21—The Tacoma-Pierce County Health Department issued closures for Sunnyside Beach Park and Chambers Creek Regional Park beaches Wednesday in light of a sewage spill. An alert from the state Department of Ecology said the spill was a result of a crushed sewage line that discharged sewage into Flett Creek. Flett Creek flows into Chambers Bay. Cindy Callahan, environmental health specialist supervisor at the Tacoma-Pierce County Health Department, said the issue has been corrected and water samples are being taken at the beaches. The locations will remain closed until the water is deemed safe again.
