On August 15, 1988 the Board of Supervisors appointed an eleven-member citizens' committee to develop policies designed to guide future growth and development in the Fort Valley area. The committee selected the issues of concern which included water, fire protection, solid waste disposal, utilities, environmental quality, roads, and land use. The study area decided upon was that depicted on the Department of Community Development's Fort Valley Zoning Map. This includes all lands outside of the incorporated City Limits of Flagstaff on both sides of Fort Valley Road/Highway 180 out to and including the Fort Valley and Baderville areas. The Committee decided to exclude Hart Prairie and Kendrick Park. Throughout the process, the Committee thought of the study area as being in tow distinct parts. South Fort Valley included the Lockett property, Colton Ranch area, Mount Elden Lookout Road, Schultz Pass Road, the Magdalena/Van Sickle area, Forest Hills and Hidden Hollow. North Fort Valley included Fort Valley Ranch, both sides of Highway 180 in the main valley, and Baderville.

Saguaro National Park encompasses two geographically distinct areas: Rincon Mountain District and Tucson Mountain District. Of the two, only Rincon Park has significant riparian habitat due to Tanque Verde Ridge. The scope of this study includes Rincon Creek, its tributary riparian areas and Tanque Verde Creek riparian tributary areas within or immediately adjacent to the Park. Both of these creeks have riparian resources that will likely be impacted by proposed development adjacent to the Park boundaries.
