This week's circulars

Associate engineer Lance Bunch and assistant division manager Eric Johnson with City of Tacoma's Environmental Services talk about the 2,500-foot floodwall that was built around Tacoma's Central Treatment Plant earlier this year to combat the threat of landslides sweeping pollution into Commencement Bay. The wall, part of a $75 million project, stretches 25 feet underground.
