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 document has been prepared to fulfill the requirements for a hydraulic study for the Cave Creek Landfill operated by Maricopa County.
This addendum to the 2005 work plan identifies how additional assessment of groundwater features and contamination at Cave Creek Landfill will be conducted.
This Additional Site Characterization Work Plan presents a strategy for collecting site characterization information at the closed Maricopa County Cave Creek Landfill to support ongoing remedial action planning for trichloroethene-impacted groundwater underlying the site. The Work Plan supplements previous remedial investigation work plans prepared to characterize the nature and extent of site contamination.
To evaluate whether VOCs are migrating out of the landfills into the vadose zone, a soil vapor survey of the soil beneath the landfill bases was performed. Permanent vapor monitoring probes were installed and then sampled twice for VOCs. Groundwater beneath the landfills has been impactd by VOCs, namely TCE, DCE, and toluene.
During the period of 1965 through 1984, Maricopa County operated a landfill leased from the U.S. Bureau of Land Management. In 1982 the County leased a separate parcel from the State for the development of a new landfill. The landfill stopped accepting waste in 1998.
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.
