The Arizona Department of Transportation and the Maricopa Association of Governments are cooperating in the designation of a specific route for the CANAMEX Corridor in the Maricopa Region. Kimley-Horn and Associates, under contract to ADOT, provided technical assistance to ADOT and MAG in support of the high-level evaluation of route alternatives. The purpose of this study is to provide technical assistance, not to evaluate or select a preferred route alternative.

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.

The purpose of this report is to provide a proof of concept for a different, alternative method for evaluating police agencies. Our method is couched in a comparative approach, which will allow agencies to compare their performance to other police agencies. This report assesses police performance through the perceptions and experiences of recently booked arrestees. By comparing the perceptions and experiences of recently booked arrestees from different jurisdictions we can begin to contextualize results and observe differences that might serve as an early warning of a problem or serve as an indicator of success.

The analysis plan and the format of this report are derived from numerous meetings held over more than an eighteen month span with the AARIN project advisory board, Maricopa County leadership, and representatives from MCSO. Following the guidance of the advisory board, the dissemination strategy for the AARIN project shifted from a single, broadly scoped annual summary report supplemented by smaller topic-specific reports into shorter, individual reports tailored to the specific needs and wants of six key county criminal justice agencies. Meetings with MCSO representatives regarding their individualized report indicated they would be most interested in a broad analysis akin to the old annual reports. Given the MCSO’s need for the broadly scoped analysis as opposed to a topically-focused and interpretive report, the report here primarily provides analyses across most of the core instrument elements, presented in tabular form, with a list of key findings and highlights.

The Arizona Arrestee Reporting Information Network is a drug abuse monitoring system that provides on-going descriptive information about drug use, crime, victimization, and other characteristics of interest among individuals arrested in Maricopa County, Arizona. In five facilities throughout the county, professionally trained interviewers conduct voluntary and confidential interviews with recently booked arrestees. Questions focus on a range of topics including demographics, patterns of drug use (lifetime and recent), criminal activity, gang affiliation, victimization, mental health, citizenship, and treatment experiences. Each interviewee also provides a urine specimen that is tested for the presence of alcohol and/or drugs.
