Pima County's Cienega Creek Natural Preserve surface water and groundwater monitoring project. This report summaries PAG's groundwater and surface water monitoring between July and June each fiscal/ monitoring year. The report contains monitoring methodology, comprehensive maps, and graphs of trends for surface flow volume, wet-dry flow lengths, groundwater levels and water chemistry. It also contains information on drought, erosion and repeat photography.

This study is to update the current plan entitled "Unified Nogales/Santa Cruz County Transportation 2000 Plan." The local governments need a fresh look and new approach to developing their transportation plan. Purpose: The purpose of this study is to create a useful, workable transportation system planning document that contains a realistic and achievable program for implementing transportation system improvements throughout the city and the county.

Landscaping planted after January 1, 1987 within publicly owned rights-of-way and irrigated with groundwater may be planted only with plants listed on the ADWR Low Water Use/ Drought Tolerant Plant List for the Tucson AMA. The director may waive this requirement under special circumstances. This list can also be used as a resource for residents and businesses that are interested in conserving water. The list provides a wide array of plants to accomplish a variety of low wateruse landscape designs.

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.

This report summarizes the results of an economic impact analysis of the Rosemont Copper Project, an open-pit mining operation to be developed on a 15,000 acre site in Pima County about 30 miles southeast of Tucson. The analysis employed the REMI PI+ regional economic forecasting model to estimate the economic impacts of the Project for the Cochise/Pima County/Santa Cruz Counties study area, for the State of Arizona, and for the United States.
