During the planning process for the SDCP, concerns were raised regarding loss of property tax revenue as well as adverse tax base impacts of Pima County purchasing parcels for open space. This report assesses impacts in two ways. First, the net assessed values of the open space parcels before purchase are compared to the sum of the net assessed values of all parcels in Pima County and in each applicable school district. Second, the property taxes assessed by Pima County and applicable school districts on each open space parcel before purchase is compared to the sum of the property taxes assessed on all parcels within Pima County and applicable school districts.

Public finance—taxes and other revenues collected by government and the expenditure of those revenues—always has been somewhat controversial because of wide philosophical differences among residents regarding the role that government should play in providing public services and in collecting taxes and fees from its residents. Recently, public finance in Arizona has become a prominent public issue due to the need to resolve the deficits that afflict state government and most county and municipal governments in Arizona.

Arizona is emerging from one of the worst state budget crises in the nation. Entering 2003, its projected deficit, measured as a percentage of the general fund, was the fifth largest in the country.1 The state had slashed spending in 2002 in the face of a $900 million deficit, but still faced a $400 million shortfall for fiscal year 2003 and an estimated $1 billion deficit in fiscal 2004. Although improved revenues have reduced the anticipated gap, fundamental underlying problems remain concerning the ability of lawmakers to control the budget. Some observers consider this a revenue problem, others a spending problem. Our concern in this paper is whether state lawmakers have enough control over either revenue or spending.
