The Board of Supervisors make an estimate of the different amounts required to meet the public expenditures/expenses for the ensuing year, also an estimate of revenues from sources other than direct taxation, and the amount to be raised by taxation upon real and personal property of Graham County.
This study focuses in the area surrounding the municipalities of: Town of Pima, City of Thatcher and City of Safford. The junction of the two major state routes, US 191 and US 70 is located in the heart of these communities and serves as major arterials for local travelers. Parsons Brinckerhoff has been commissioned by ADOT to perform this preliminary assessment for the development of an alternate route through the Thatcher/Safford/Pima area.
In 1992, Graham County conducted a transportation study for the Gila Valley Region. This study prepared a long-range transportation plan and a transportation improvement program. Many of the improvements have been completed. The purpose of this study is to update the 1992 transportation plan and to address the current issues within the area.
The Graham County, Safford, Thatcher, Pima Small Area Transportation Study was initiated by Graham County, in conjunction with the Arizona Department of Transportation, to develop a countywide, long-range multimodal transportation plan for this growing rural Arizona community. The project sponsors selected the PB Americas team to conduct this study under the direction of a Technical Advisory Committee, which included representatives from Graham County, City of Safford, Town of Thatcher, Town of Pima, Southeastern Arizona Governments Organization, and ADOT.
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.
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.
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.
