Puget Sound Beach CSO Control ProjectsCSO control needs in the project basinsSeptember 2011 Update: the four CSO control projects have moved to the project design phase. To learn more, follow the links in the upper right column.
On December 22, 2010, King County announced a recommended proposal for CSO control (underground storage tank) in the South Magnolia basin.
On December 8, 2010, King County announced a recommended proposal for CSO control (green stormwater infrastructure) in the Barton basin.
On December 8, 2010, King County announced a recommended proposal for CSO control (underground storage tank) in the Murray basin.
On October 7, 2010, King County announced a recommended proposal for CSO control (underground storage pipeline) in the North Beach basin.
 As part of its CSO Control Program, King County has identified CSO control approaches for the four project basins along Puget Sound in Seattle. These locations are top priority because people are most likely to come in contact with water during recreational activities such as swimming. State Department of Ecology (DOE) regulations require CSO facilities to have no more than one CSO event per year on a long term average. These CSO facilities do not meet this requirement at this time. Figures below are based on a 2008 report to DOE.  - North Beach - North Beach discharged on average 10 times each year, a total of 2.2 million gallons per year.
- South Magnolia - South Magnolia discharged on average 19 times each year, a total of 31 million gallons per year.
- Murray - Murray discharged on average 5 times per year a total of 5 million gallons off Lowman Beach.
- Barton - Barton discharged on average 4 times per year a total of 4 million gallons into Puget Sound off Fauntleroy.
