This study was developed to identify the resources and applicable methodology for the delineation of primary flood corridors.
The purpose of the Phase I study is to evaluate existing drainage conditions and to identify alternative flood control/floodplain management strategies which warrant further consideration.
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.
This report describes the hydrologic and hydraulic analysis. Development in the lower end of the watershed has occurred without knowledge of the floodplain's characteristics.
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.
This report is the first phase of a study to provide a basin management plan for the Tucson Mountain Drainage Basin. Phase II will identify and evaluate alternative specific solutions to flood plain management measures with Phase III accomplishing conceptual designs for the selected alternatives.
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.
This report describes the development of base and future socioeconomic estimates for the Pinal Corridor Planning Model, developed by ADOT to support the evaluation of potential new highway corridors in Northern Pinal County. This section presents a summary of the methodology, data sources used, and historical trends in population and employment growth. The following two sections present the base and future year methods and resulting estimates of population and employment.
A landmark assessment of infrastructure needs in Arizona was produced by the L. William Seidman Research Institute in May 2008 for the Arizona Investment Council (AIC): "Infrastructure Needs and Funding Alternatives for Arizona: 2008-2032", that addressed infrastructure needs in four categories: energy, telecommunications, transportation, and water and wastewater. The information from the AIC report is a major input to the report that follows. Other types of infrastructure — most notably education, health care, and public safety — also are analyzed here to provide a more complete picture of infrastructure needs in Arizona. The goals of this report are to place Arizona’s infrastructure needs into national and historical contexts, to identify the changing conditions in infrastructure provision that make building Arizona’s infrastructure in the future a more problematic proposition than in the past, and to provide projections of the possible costs of providing infrastructure in Arizona over the next quarter century.
A community assessment of Tempe by its Police and Fire Departments, to identify significant trends in population demographics and economic development, as well as growth of Arizona State University. These trends are analyzed so that more informed decisions on public safety staffing needs can be made.
