This inventory includes emissions of coarse particulate matter <10 µm in diameter (PM10), fine particulate matter < 2.5 µm (PM2.5), nitrogen oxides, sulfur oxides, and ammonia. Emissions are calculated for both Maricopa County and the PM10 nonattaiment area. Annual totals as well as typical daily emissions are provided for all source categories.

The purpose of the ambient air monitoring network is to sample air pollution in a variety of settings, assess the health and welfare effects, and assist in determining sources of air pollution. In general, six basic monitoring objectives and five measuring scales are used to determine the network design. Since it is physically and fiscally impossible to monitor the air in every location, representative samples must be obtained. These samples are determined by using the monitoring objectives and the spatial measurement scales. The network must be dynamic enough to maintain a current representative sample of the air quality. Air quality issues such as eight-hour ozone non-attainment boundaries and permits for new sources are diverse and controversial subjects for the citizens of Maricopa County. With its robust air monitoring network and mobile monitoring tools, the department strives to provide the most reliable and relevant air monitoring data to the public.

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.

This Campaign Effectiveness Study, conducted for the Pima County Department of Environmental Quality, was designed to evaluate the specific effectiveness of the 2013-2014 Clean Air and Clean Stormwater Program Campaigns. This project analyzed and tracked the overall effectiveness of the Clean Air Program after 24 campaign sessions. For the second consecutive year, the survey also measured and tracked attitudes, knowledge, awareness, and behaviors related to stormwater management for the Clean Stormwater Program Campaign.

This Campaign Effectiveness Travel Behavioral Study, conducted for the Pima County Department of Environmental Quality, was designed to evaluate the specific effectiveness of the 2012-2013 Clean Air Campaign, as well as analyze the overall effectiveness of the air quality media campaign after 23 campaign sessions. New to the current study, the survey also measured baseline awareness/knowledge related to storm water and hazardous waste issues.

One in a series of long-range transportation planning studies being conducted by the Maricopa County Department of Transportation to assess the ultimate corridor footprint requirements to enable consistent implementation across multiple jurisdictions. The study area for this project includes Peoria Avenue from the future Jackrabbit Trail Parkway alignment to Dysart Road (Peoria Avenue Corridor). The study area generally encompasses a two-mile wide corridor centered on the existing Peoria Avenue.

One in a series of long-range transportation planning studies being conducted by the Maricopa County Department of Transportation to evaluate future parkways identified in the Maricopa Association of Governments framework studies. The Yuma Parkway study area is approximately 13 miles long and two miles wide, and is generally centered on the Buckeye Road/Yuma Road section line, from one-half mile west of Salome Highway to one-half mile east of Palo Verde Road.

The purpose of the Hidden Waters Parkway study is to document conditions along the parkway corridor, identify potential fatal flaws and develop an alignment alternative that meets the future traffic needs identified in the Hassayampa Framework Study. The recommended alternative will establish a roadway footprint that may be used as a guide for local agencies and development within the corridor.
