In 2008, King County reported that the Barton CSO facility has four overflows per year on average that discharge a total of four million gallons into Puget Sound off Fauntleroy. A planned upgrade of the Barton Pump Station will increase capacity to manage a portion of the combined stormwater and wastewater. Alternative means being considered must be capable of managing a volume of 100,000 to 200,000 gallons of peak flows, depending on location, to meet regulatory requirements.

Information about alternative means for CSO control projects in Barton is provided below, including some of the benefits and challenges King County has identified for each.
