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.
This study, and the resulting transportation plan, is funded through ADOT’s Planning Assistance for Rural Areas (PARA) program. ADOT and the Town of Colorado City have retained the consultant team of Wilbur Smith Associates to conduct the study under the oversight and direction of a Technical Advisory Committee (TAC) that includes members from the Town of Colorado City; adjacent Hildale City, Utah; Mohave County; the Arizona Department of Transportation Multimodal Planning Division; the ADOT Flagstaff District Engineer’s office; and other interested parties.
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.
Grace Neal Parkway and Bank Street are located in the northern Kingman area partially outside of the Kingman city limits. This report discusses of creating a new arterial roadway providing safety and convenience for vehicular traffic and pedestrians. Although Grace Neal is referred to as a parkway, its designation for design is arterial.
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.
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 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.
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.
