The purpose of the Flood Response Plan is to reduce the potential for property damage and loss of life resulting from floods on the Beaver Dam Wash at the community of Beaver Dam. This report is intentionally short and concise to make it easily usable during a flood emergency.
This document has been prepared to fulfill the requirements for a hydraulic study for the Cave Creek Landfill operated by Maricopa County.
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.
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.
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.
This Technical Data Notebook has been prepared in support of a Letter of Map Revision submittal to amend the 100-year floodplain, or Special Flood Hazard Area associated with Finger Rock Wash in Pima County, Arizona. The purpose of this LOMR application is to revise the effective Flood Insurance Rate Map SFHA boundaries based on updated and more detailed information. No new hydraulic structures are present within the study limits.
Purpose of this report is to provide a detailed analysis of the runoff characteristics of the Diamond Bell Ranch area.To this end, HEC-HMS models were generated to analyze the runoff under existing watershed conditions.
This report documents the existing drainage conditions related to Silverbell Trails Estates roadways and 100-year flow depths and includes qualitative and quantitative analyses of the existing hydrologic and hydraulic conditions.
The purpose of this study is to determine the hydrologic and hydraulic impacts of the Aspen Fire of the summer of 2003 on the Sabino Canyon and Carter Canyon watersheds, which are in the vicinity of the Town of Summerhaven, located on Mount Lemmon in the Santa Catalina Mountains, Arizona.
