The 2011 Solid Waste Management Plan Revision, "Picking Up the Pace Toward Zero Waste" (2011 Revision), describes how Seattle will manage the city's solid waste over the next 20 years. We finished revising the plan in the summer of 2013 with updated artwork and chapters below. The State of Washington Department of Ecology approved the revised plan on June 25, 2013. Hardcopies are available at the Seattle Public Library, Downtown Branch.

The City is in the process of updating the 2011 Revision.
