8-13D-9-3: POPULATION AND DEVELOPMENT TRENDS:
The following table documents population estimates and projections for Ada County and planning areas within the County. These numbers have been adopted by the Ada Planning Association as the basis for planning activities in Ada County. Future population increases for Ada County have been forecast at an average annual rate of approximately three percent (3%). The rate of growth for 1990-1995 three and eight-tenths percent (3.8%), is considerably greater than the two percent (2%) average rate seen between 1980 and 1990.
Growth Patterns: The number of households continues to increase dramatically, surpassing population growth. This rapid growth pattern reflects a decrease in persons per household. Increase for the period 1990-1995 is estimated to be approximately forty-eight thousand two hundred four (48,204) people for a 1995 estimated population of two hundred fifty-three thousand nine hundred fifty-four (253,954). Ada Planning Association (APA) data projects that between 1995 and 2000, thirty-six thousand (36,000) new residents can be expected for a total of two hundred ninety thousand (290,000).
Hidden Springs is located within the Ada Planning Association Area called Rural. More specifically it is located mostly within the Traffic Zone 211 which lies north of Hill Road and between Pierce Park and Seaman's Gulch Roads. The data for Traffic Zone 211 shows population doubling and households increasing by approximately one hundred percent (100%) from 1990 to 1995.
Alternative Plans: Ada County, the City of Boise and other local agencies have been moving forward in their evaluation of a land use plan for the foothills area, which covers the foothill area from Lucky Peak west to Highway 55 and includes the Dry Creek Valley and Hidden Springs. The Ada County Comprehensive Plan has been updated and adopted. The County anticipates consideration of the foothills plan in 1997.
Residential Development Patterns: Residential development in the Dry Creek Valley has historically been farm and ranch related. Since the mid-1980's however, significant numbers of rural residential homes on sites ranging from one to twenty-five (1-25) acres have been constructed. The pattern of rural residential construction along Dry Creek on the west side of Highway 55 is very extensive. Homes in that area are generally on lots from one-fourth (1/4) acre to five (5) acres. Demand for residential lots in Dry Creek to the east of Highway 55, which includes the Hidden Springs vicinity, is reported by property owners and realtors to be very high, although supply to this point has been limited to lot splits and small subdivisions.
Rapid growth in the Boise area is resulting in new development in a number of areas that have previously been predominantly rural. Hidden Springs, if built out completely in a fifteen (15) year period through 2010, would accommodate three percent (3%) of the population growth projected for Ada County.
Development Rationale And Justification: Hidden Springs is intended to accommodate and respond to the continued population growth Ada County is anticipated to experience. The Dry Creek Valley is identified in the current draft (and all previous drafts) of the city of Boise foothills plan as an area appropriate for development and urban densities. The physical and environmental characteristics of the Dry Creek Valley as well as the location of the valley in relation to existing and anticipated transportation networks make the area an appropriate place to accommodate planned community growth needs. Hidden Springs is also closer to the primary employment centers than much of the residential development occurring on prime farmland on the urban fringes.
Hidden Springs, at build-out, projects a total population of two thousand five hundred eighty-eight (2,588), with school enrollment at five hundred eighteen (518). The project will provide a unique rural community and development alternative that is otherwise not available in Ada County.
