2006 Water Comprehensive Plan - City of Bellevue

Issaquah is in the process of obtaining additional water supply from Cascade through a recentlyconstructed 24-inch water supply line in Newport Way from approximately 161 st Avenue SEeast to Issaquah. This new Issaquah water supply line is connected to the Seattle regional supplysystem by a 24-inch pipe formerly owned by Bellevue. Bellevue transferred ownership of thispipeline to Cascade in 2006.In 2005, Issaquah annexed the area of King County along the southwest shore of LakeSammamish known as Greenwood Point and South Cove. This area is currently provided waterservice by Bellevue. Issaquah has given preliminary indications of their intention to own andoperate the utility facilities serving their citizens in this area. It is therefore anticipated that aninterlocal agreement will be developed at some time in the future to transfer the water facilitiesin this area from Bellevue to Issaquah.Coal Creek Utility DistrictCoal Creek Utility District, formerly known as Water District 107, is south of Bellevue and eastof Lake Washington. The District was formed through the consolidation of Water DistrictsNo. 92, 95, and 102. In 2003, the portion of the District that lies within the City of Bellevue wasassumed by Bellevue.The District’s current service area is almost entirely within the City of Newcastle and containsseveral undeveloped areas. These areas should be developed in a way that maintains the loopedsystems of Bellevue and Coal Creek Utility District and avoids water main duplication.The portion of Bellevue’s water system that is south and east of the Coal Creek Parkway issupplied with water from the District through eight metered interties. These interties are locatedalong the Bellevue/Newcastle city limits. The District is responsible for operation andmaintenance of the major supply facilities (regional supply inlets, pump stations, and reservoirs)for this area. These facilities are identified as joint use facilities in the interlocal agreementbetween Bellevue and the District.Water District No. 1Water District No. 1 is located north of Bellevue’s water service area and is within the Town ofYarrow Point. Bellevue now operates and maintains the District’s water system and supplies theDistrict with water, per a 2005 interlocal agreement. Prior to Bellevue taking over operation andmaintenance of the District’s system, the District was required, under the terms of the interlocalagreement, to construct significant system improvements to eliminate all identified waterdistribution problems within the District.3-16
