By establishing the District, the Arizona State Legislature created an entity charged with keeping county residents safe from flood hazards and established an independent funding source for essential projects. The District is a municipal corporation and political subdivision of the State of Arizona. The Maricopa County Board of Supervisors doubles as the District's Board of Directors and receives counsel from the Flood Control Advisory Board comprised of county citizens.

The 2009 Comprehensive Floodplain Management Plan and Program is intended to be used as a general guide for future decision-making in District activities. The Plan aims to present adequate background information to aid District staff in prioritizing areas for future studies and projects. The Plan identifies historic flooding events, reviews the District's efforts to solve flooding problems, and formulates five-year plans to reduce flooding through flood control project construction, floodplain identification, and planning programs throughout the county.

In early 2009, an Exploratory Committee was formed to investigate the potential creation of a Veterans Court in Maricopa County, Arizona. The Committee’s initial efforts have focused on examining existing Veterans Courts and determining the size and scope of the problem (i.e., the number of veterans in the county jail). This report provides an overview of information on veterans in the Maricopa County Jail System, drawing on data collected by the Arizona Arrestee Reporting Information Network (AARIN). This report is intended to assist the work of the Veterans Court Exploratory Committee.

The purpose of this report is to use data from a sample of recently booked arrestees in Maricopa County to examine the scope and nature of Maricopa County’s gang problem. In particular, this report supplements data presented in the bi-annual report on gangs conducted by the Arizona Criminal Justice Commission, which relies on official police data and their occasional white paper on gangs that relies on self-report data from school youth. We organized our analyses around six research questions: (1) what proportion of adult arrestees are involved in a gang, and what are the socio-demographic differences between those who are associated with a gang and those who are not; (2) what are the rituals associated with gang joining; (3) how do gang and non-gang arrestees differ in their experiences with crime, drug use and victimization; (4) what is the organizational structure and composition of gangs; (5) how do members socially identify with their gang; and (6) how and why do members leave their gang?

In 2006, the Bureau of Justice Statistics awarded a State Justice Statistics grant to the Arizona Criminal Justice Commission’s Statistical Analysis Center to conduct research on homicide in Arizona. The Center, with assistance from local law enforcement officials, and researchers from the School of Criminology and Criminal Justice at Arizona State University, collected homicide data from the following sources: Supplemental Homicide Reports, law enforcement homicide case files, and autopsy reports. The purpose of this report is to provide a general description of the scope and nature of the homicide problem in Arizona. Specifically, this report examines the general characteristics of victims and offenders, the circumstances surrounding homicide incidents, temporal patterns when homicides occur, and the geographic characteristics where homicides took place.

Over the past year anecdotal evidence from media reports has suggested disproportionate levels of crime and violence occurring at Circle K stores in the Phoenix metropolitan area. Criminal events depicted by the media often took the form of individuals engaging in some type of minor criminal activity at a Circle K, and the events spiraling out of control. As a consequence of these observations, and subsequent federally sponsored research examining problem places in Glendale, Arizona, faculty and staff from the Center for Violence Prevention and Community Safety at Arizona State University reached out to several valley police departments and requested official data to more systematically examine this potential problem. This report presents our findings and our recommendations.
