The purpose of this study is to provide flood and erosion hazard information for Woodland Wash for us in floodplain use permitting and floodplain management.
This study was prepared to provide a drainage condition for Tanuri Wash. Hydrologic and hydraulic analyses were conducted. A floodplain map was created based on the hydraulic analysis.
The Arizona Department of Transportation’s (ADOT’s) process for working with Local Public Agencies (LPAs) in the development and delivery of their transportation projects has evolved over the years. Recent changes in Arizona’s economy have reduced the distribution of state funds for local transportation projects, which has increased the demand for federal funding sources. In response to the anticipated increase in LPA projects desiring the use of federal funds and the continuing need to meet state and local transportation requirements, this updated manual highlights the steps necessary to capably deliver LPA projects in compliance with federal, state, and local requirements.
The ADOT Local Public Agency Projects Manual has been a collaborative effort among the various Divisions, Groups, and Sections within ADOT, as well as the Federal Highway Administration (FHWA) Arizona Division, with input from LPAs. ADOT would like to express sincere gratitude to Logan Simpson Design Inc. for successfully facilitating that effort and for their contribution to the production of this manual. Their hard work and in-depth coordination with ADOT and FHWA staff has been invaluable to the preparation of this manual.
"Traversing parts of Pima and Santa Cruz counties, the Scenic Road follows State Route 83 (milepost 58 to 33) and State Route 82 (milepost 32 to 4.5). The road is rural in character and ... passes through the communities of Sonoita ... and Patagonia."--Page 2
This "document was prepared in 2008-2009. In addition to field reviews and available research, significant information was obtained from public opinion and concerns voiced during the public and Citizen Advisory Committee meetings held along the route. The primary objective of this report is to document desired efforts along the Fredonia-Vermilion Cliffs Scenic Road that will sustain its resources for future generations. Additionally, this document fosters the necessary relationships required to promote and protect the intrinsic qualities that define this scenic road experience."--Foreword
From May 2005 to June 2005, the Arizona Department of Environmental Quality conducted a study, Potable Well Sampling Task 4.0, to determine if the chromium and chromium VI plume due to the discharge of the Pacific Gas and Electronic Topock Compressor Station has migrated under the Colorado River and impacted water supplies in Arizona. The ADEQ investigated the total chromium and hexavalent chromium (chromium VI) concentrations in (1) public water supply wells, (2) combined industrial and domestic water supply wells, and (3) private domestic water supply wells at Topock and Golden Shores, Arizona. The communities of Topock and Golden Shores have expressed their concerns regarding the findings. Thus, the ADEQ requested the Arizona Department of Health Services to evaluate the potential health effects of exposure to well water contaminated with chromium.
The Arizona Department of Health Services completed this health consultation at the request of the Arizona Department of Environmental Quality. This consult evaluates whether soil vapors from volatile organic compounds in the subsurface near the Silver Creek Subdivision in Tucson, Arizona are present at levels that may cause adverse health effects.
