This report presents the results of an engineering analysis performed to assess the existing potential for flooding and erosion along Green Valley drainageway #9 and presents conceptual plans for recommended improvements. This study extends from La Canada Drive at the downstream end to the La Canoa Land Grant Boundary at the upstream end.
Tucson Water's Valley View Reservoir site and Flecha Caida Ranch Estates #9 has experienced numerous drainage-related problems,including inundation, erosion, and limited access during the rainy season. A portion of the reservoir site and approximately one-half of the subdivision are both located in the 100-year flood plain.
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.
The purpose of this study, which represents Phase I, is to determine long range planning and land use policies for flood control and floodplain management in the southwest area.
The purpose of this report is to assist the Pima County Board of Supervisors in assessing whether the Black Wash area requires area-specific flood control policies.
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.
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 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 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 this study is to (1) develop a fundamental understanding of the problems that exist, and (2) perform a cursory examination of possible management approaches identifying those that appear most plausible for further consideration.
