This report is intended to revise the previous watershed hydrologic and hydraulic calculations for the proposed extension of Camino Del Sol Road. This study is necessary because of significant land use changes within the watershed.

This parcel has some houses already constructed, but most of the area is left undeveloped and can be classified as desert foothills. The objective of this report is to determine all of the flows generated by a 100-year storm in excess of 100 cfs and then map the flood-prone boundaries for the associated channels.
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 purpose of this study is to define the scope of the problem and to recommend alternative approaches which would reduce the flood damage potential associated with future private driveway access across the watercourses and to provide more hydrologic and hydraulic information.

This plan has focused on two program areas: 1) floodplain management through revised floodplain delineations and assessment of subsequent FEMA mapping revisions; and 2) basin-wide planning issues involving both short- and long-term drainage infrastructure and regulatory needs.

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 study developed the 100-year floodplain limits within the watershed and identified the area between Westover Avenue and Valencia Road as a major flood hazard area affecting most of the properties along the channel.

This study proposes to reduce flood damages from both Tanque Verde Creek and offsite flows, as they affect the Fortyniner's Country Club Estates and the Arbor Vista subdivisions.

The purpose of this study is to revise the existing Flood Insurance Study and Flood Insurance Rate Maps for a portion of the Canada del Oro Wash. This information will be used by Pima County to update existing flood plain information.
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.
