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.
