A detailed hydraulic analysis of Idle Hour Wash for the purpose of preparing a Letter of Map Revision.
The objectives of this report are to document the on-site and off-site hydrologic and hydraulic assessment of the site and its characteristics, quantifying existing conditions peak discharges, and define the limits of 100-year on-site floodplains.
Phase IIA focuses on identifying alternatives for mitigating the hazards and problems, evaluating the alternatives for flood mitigation potential and cost effectiveness, and recommending a preferred alternative and flood control policy.
The Floodplain Management Act of 1973 authorized Arizona counties to adopt rules and regulations concerning management of floodplain areas. The Pima County Board of Supervisors, which sits as the Pima County Flood Control District Board of Directors, organized the Pima County Flood Control District on June 5, 1978. The District is responsible for floodplain management activities for unincorporated areas in Pima County (with the exception of national forests, parks, monuments, and Indian Nations) and for the City of South Tucson.
The Arizona Department of Transportation was authorized in 1996 to administer a State Infrastructure Bank under a cooperative agreement with the Federal Highway Administration. The Highway Expansion and Extension Loan Program (HELP) was established. The financial statements present only the funds comprising the Fund and are not intended to present fairly the financial position or results of operations of the Department.
The HELP program is meant to be a funding tool to accelerate needed highway projects throughout the state. Board Funding Obligations are an important part of the HELP capitalization and the current stress on the State's General Fund has impacted our ability to use BFOs as a funding source for new loans. Though $140 million of BFOs are authorized by statute to capitalize the HELP, the State Treasurer was required to call all outstanding BFOs in April 2009. Consequently, the State Transportation Board and the Department have suspended the HELP program given the uncertainty of a long term funding source.
Projected transportation revenues fall short of estimated needs and the Arizona Legislature should consider a task force to study options for addressing transportation revenue needs.
The purpose of the Flood Response Plan is to reduce the potential for property damage and loss of life resulting from floods on the Beaver Dam Wash at the community of Beaver Dam. This report is intentionally short and concise to make it easily usable during a flood emergency.
The Flecha Caida study area encompasses approximately eight square miles of the foothill region of the Santa Catalina Mountains. The three major washes studied include Finger Rock Wash, Valley View Wash, and Flecha Caida Wash. One tributary (Sky Club Wash) to the Valley View Wash and three tributaries to the Finger Rock Wash were also included in this study.
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.
