2010 Water Comprehensive Plan

2012 Amendment to the 2010 Water Comprehensive Plan

On February 13, 2012 the Sammamish Plateau Water & Sewer District Board of Commissioners adopted the 2012 Amendment to the 2010 Water Comprehensive Plan for distribution for comment and approval by King County, City of Issaquah and the Washington State Department of Health. This 2012 Amendment formally identifies inclusion of the Overdale Water Association service area ("Overdale Service Area") as an area of direct water service provision by the District, and allows provision of full service from the District to the Overdale Service Area. The Overdale Service Area addition is comparatively small, adding only 100 acres to the over 28 square mile District, and is generally located between SE 52 and SE 56th Street, and between 228th and 236th Ave SE (if both extended), within the City of Issaquah.
