Info

Projections forecast a total population increase from 2005 to 2025 of approximately8,678 residents for the water system service area, which translates into an average annualpercentage population increase of approximately 0.35 percent. Projected populations are shownby major water utility operating area in Table 3-2. Bellevue’s three major operating areas areshown in Figure 6-1 in Chapter 6.LAND USELand Use in Bellevue City LimitsLand use within Bellevue is governed by the City of Bellevue Comprehensive Plan. The planaddresses current land use within the city and future land use direction. This WaterComprehensive Plan was prepared using the land use information contained in the 2004 City ofBellevue Comprehensive PlanThe City is currently evaluating potential changes in land use within the “Bel-Red Corridor”which is generally defined as the area east of I-405 between SR-520 and Bel-Red Road,including properties along the south side of Bel-Red Road. The Bel-Red Corridor Project isexamining 5 alternatives (including a no-action alternative) for future land use in the area. Eachalternative was preliminarily evaluated to identify potential impacts to the water system andfuture water demands. No significant impacts were identified. As the project progresses, andalternatives are more specifically defined, the City will continue to re-evaluate them forpotential impacts to the water system.The City is bounded on the north by Kirkland and Redmond, on the west by Lake Washington,on the east by Lake Sammamish and Issaquah, and on the south by Newcastle and the CougarMountain Regional Park. There is limited potential for water system expansion into small areasjust north of the Cougar Mountain Regional Park. The City has a sphere of influence agreementwith the City of Issaquah. This agreement was approved jointly by both city councils in July1979 and then reaffirmed in August 1987. It identifies a line to which these cities willeventually expand. For each city, the area between the sphere of influence line and the City'scurrent boundary is known as the potential annexation area (PAA).Figure 3-2 illustrates Bellevue's existing land use. Bellevue's sphere of influence is included inFigure 3-3, which depicts ultimate land use based on the City's Comprehensive Land Use Plan.All zoning within the city limits is consistent with the Comprehensive Land Use Plan, asrequired by the Growth Management Act. Figures 3-2 and 3-3 were prepared by the City ofBellevue Planning and Community Development Department. It should be noted that forunincorporated areas of King County, there may be minor discrepancies between the City'sComprehensive Land Use Plan, and King County’s Comprehensive Plan. King County planningtakes precedence in these areas, and should be referred to for specific zoning and planninginformation, until and unless the area in question is annexed to the City of Bellevue.3-3
