Chambers Creek Wastewater Treatment Facility


As part of ongoing development at the 930-acre Chambers Creek Properties, GreenWorks developed schematic design and construction documents for long-term sustainable stormwater strategies integrated with perimeter landscape buffers for the existing Chambers Creek Wastewater Treatment Plant (CCWTP) wastewater treatment plant and planned expansions. Working closely with Pierce County staff, Brown & Caldwell engineers, and Michael Willis Architects, GreenWorks developed the landscape buffer concept to visually and physically screen the treatment plant.


The buffer serves to blend the treatment plant area harmoniously with the dramatic landscape of south Puget Sound, surrounding land uses and future development on and off the plant site. The design incorporates stormwater management facilities that treat plant runoff, provide new recreation trails that connect with existing trail networks, and improve wildlife habitat. The buffer must also accommodate support facilities for bus traffic and large crowds attending the 2010 PGA US Amateur’s Open and the 2015 US Open to be held on the adjacent Chambers Creek Golf Course. In addition to the perimeter buffer, GreenWorks is working on the redevelopment of the plant entrance to improve visibility and enhance circulation.
