This update of the Phoenix-Mesa Gateway Airport Master Plan has been undertaken to evaluate the airport's capabilities and role, to review forecasts of future aviation demand, and to plan for the timely development of new or expanded facilities that may be required to meet that demand. The ultimate goal of the master plan is to provide systematic guidelines for the airport's overall development, maintenance, and operation.

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.

Covers an area in southeastern Pima County that drains the Arivaca Creek watershed. The purpose of the report is to estimate peak discharge for the 50 year storm frequency event, utilizing the rational method (Q=CiA). This method pre-dates that outlined in the Hydrology Manual for Engineering Design and Floodplain Management within Pima County, Sept. 1979, and is considered less accurate. It is recommended that this report be archived and discontinued for use for regulatory purposes.

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.
