Fort Lowell was a supply base for the United States Army “Apache Campaigns” between 1873 and 1891. Following abandonment of the fort in 1891, settlers moved in and used some fort buildings as residences, or stripped the buildings of useful materials. By the 1930s, much of the fort had fallen into disrepair or had been sold off. Eventually, the City of Tucson acquired a large portion of the old fort which became what is today’s “Fort Lowell Park.” A 5.2 acre (“Adkins”) parcel of the former fort containing several original adobe buildings was still in private ownership, and the 2004 County bond election passed a proposal to acquire the land and preserve the historic resources.

This document and the Geographic Information System file that is now a part of the County library of over 1000 coverages, gives the scientific community access to mapping that better differentiates perennial, ephemeral and intermittent watercourses, and provides more comprehensive coverage of shallow groundwater sources. This data is significant because riparian habitat is one of the most important and least protected of the habitat types in Pima County.

The purpose of this project was to compile information on groundwater withdrawals and surface water diversions near perennial streams, intermittent streams, and shallow groundwater areas previously identified by PAG for the SDCP. The information could be used to prioritize future investigations of potential impacts of these withdrawals and diversions on riparian and aquatic habitats for the SDCP.

Conducted for the Pima County Flood Control District by the Pima Association of Governments in order to determine if stormflows on the Cienega Creek have changed over time when analyzed in terms of frequency, volume, and seasonallity. In a data search that extends back to the 1950s, they were able to determine the daily mean flow, the flows over base, and the annual peak flows of the Cienega Creek.

Provides basic information about the source of surface water in Cienega Creek at the downstream end of the natural preserve, which will contribute to efforts to conceptualize and implement effective land management proposals for the SDCP. Study results indicate that the surface flow or subflow from Agua Verde Creek do not significantly influence the water in the Cienega Creek.

The initial step in the Master Plan Update for Tucson International Airport is the identification of a series of goals and objectives that will establish guidelines for the planning process. These goals and objectives reflect the input of the Tucson Airport Authority, the Long Range Planning Council, the Airport’s Planning Advisory Committee, and the Airport’s Consultants. The Goals and Objectives will ultimately form the framework for evaluating the recommended long-range development plan and ensuring that the on-going development of the airport is consistent with the airport’s overall strategic objectives.

The purpose of this report is to present the conceptual study results and recommendations for potable water and reclaimed water infrastructure requirements in the HAMP planning area. A second report has already been prepared with study results and recommendations for wastewater facilities. The projected land use assumptions and population projections used in this potable and reclaimed water conceptual plan are consistent with Pima County's Plan.
