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.

Four major statewide "tools" to help manage growth and preserve open space have been put to work in Arizona over the past five years. These include the Arizona Preserve Initiative and the closely-related Proposition 303, as well as the Growing Smarter Act and its "addendum," Growing Smarter Plus. All four tools are based in large part on a concept known as "smart growth," which is generally considered to be a set of growth management measures that attempt to strike a balance among issues of economics, environment, and quality of life. Taken together, these four growth management tools make significant changes in the way that (a) city and county governments plan and regulate their lands, (b) citizens play a role in land use issues, (c) state trust lands are managed, and (d) open space may be acquired and preserved. Many of these changes will have long-term effects for the state. This paper provides a brief overview of each of the four growth management/open space tools, a preliminary accounting of major activities each one has stimulated, and a perspective on what can be expected for the future as expressed by a selection of growth planners and other leaders of growth management in Arizona.
