Letter from Joseph J. Cotter to Carl Hayden detailing the approximate amount of patented land within the proposed borders of the national park. Thomas J. Croaff is mentioned in his belief that he owns half the land in the proposed area; however, Joseph J. Cotter disputes this claim. Ralph Cameron's mining interests in the park are also mentioned. Circa 1917.

In February of 1998, the Pima County Board of Supervisors launched what has evolved into the Sonoran Desert Conservation Plan (SDCP) -- a comprehensive effort to protect the Sonoran Desert, guide growth and rationalize land development in the metropolitan Tucson region. Proponents of this planning process maintained that the project would reconcile conflicts between human activities and conservation, providing benefits for both wildlife and economic development. Critics, however, have increasingly alleged that implementing such an initiative will adversely affect land and housing markets, increase taxes and create problems of housing affordability. Over time a pressing need has consequently grown for objective information about the possible fiscal and economic impacts of the conservation programs being assembled by Pima County. This report addresses that need. It is a tool in the form of an impartial framework for assessment that government officials, environmentalists, business people and the general public can use for debate and decision-making.

A series of 51 individual “stakeholder” interviews and two focus groups conducted with members of the Pima County business community in fall, 2001, documented significantly divided opinion about the likely economic impacts of the county’s Sonoran Desert Conservation Plan (SDCP). The results of the stakeholder inquiries were striking. Only one major finding reflected consensus, while several others revealed sharp differences of opinion in the business community about the potential economic impacts of the SDCP and associated initiatives.
