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 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.
Millstone Manor #6 is a subdivision that was recorded in the mid-1950's. All records indicate no engineering took place with regards to potential for drainage improvements. This report will address what the natural floodprone areas are and will recommend how future permits should be processed.
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 report is to assist the Pima County Board of Supervisors in assessing whether the Black Wash area requires area-specific flood control policies.
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.
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.
Offsite drainage impacts the project site from several watersheds whose headwaters lie to the northeast of the project site. This report will address the manner in which the existing offsite and the post-development onsite drainage will be conveyed across this project.
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.
This study was developed to identify the resources and applicable methodology for the delineation of primary flood corridors.
