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.

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.

Originally, the purpose of the study was to obtain either a Letter of Map Revision or a Physical Map Revision from the Federal Emergency Management Agency. Unfortunately, during the initial stages of the investigation, it became apparent that FEMA's guidelines for these types of map revisions could not be accommodated, primarily due to flow-distribution conflicts.

Conservation of the Tortolita Alluvial Fan landscape has been promoted by Pima County and Town of Marana over the past two decades. An interdepartmental team was formed to evaluate flood and debris flow hazards and the potential to create an expanded Tortolita Fan Preserve. This report provides an overview of the alluvial fan characteristics and evaluates information on the significance of the biological and cultural resources to determine of the area meets the criteria to create a federal preserve.

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.

The purpose of the study is to identify existing flooding problems for fifteen homes adjacent and west of Holladay Street which have experienced flooding in the past three years. A 1991 follow-up report is included that corrects an error in the earlier report's estimation of the split flow quantities at the intersection.
