The Decision Center for a Desert City at Arizona State University—funded by the National Science Foundation since 2004—conducts research relevant to water resources and urban climate dynamics under multiple uncertainties. This report summarizes and synthesizes research findings and achievements of DCDC after almost a decade of research and science-policy interactions. Water resource decision-making is complicated by climate change and variability, population growth and economic development, diverse stakeholder interests and fragmented governance. While these factors generate various uncertainties and complexities for decision-makers, DCDC pursues research to create a more sustainable future. The DCDC contributes to water management and urban sustainability by conducting basic science and collaborating with policymakers and stakeholders to solve real-world problems. As detailed herein, DCDC research, education, and community outreach have made substantial contributions to improving water-resource governance and climate adaptation.

The Decision Center for a Desert City at Arizona State University was established in 2004 with funding from the National Science Foundation to advance the scientific understanding of environmental decision making under uncertainty. With additional funding awarded by NSF in 2010, "DCDC II" has expanded its already extensive research agenda, engaged the policy-making community, and built stronger ties between scientific knowledge and decision making enterprises. New DCDC research has developed fundamental knowledge about decision making under uncertainty from three interdisciplinary perspectives: climate impacts, urban dynamics, and adaptation decisions. Simulation modeling and boundary organization studies cut across these themes and are a core component of DCDC activities.

DCDC is focused on developing, implementing, and studying an interdisciplinary decision-support process for environmental decision making based on principles derived from social science research. Through an integrated approach to research, education, and community and institutional outreach, DCDC is training a new generation of scientists who can work successfully at the boundaries of science and policy. Broader impacts are realized as research informs innovative solutions to society’s pressing environmental challenges. To accomplish these goals, DCDC has built a dynamic bridge between ASU and local, regional, and national policy communities to foster local to-global solutions for water sustainability and urban climate adaptation.

Prior to developing and approving new ordinances that would further regulate sex- offender distance restrictions and clustering, the Phoenix City Council approved a study to examine the nature and impact of sex-offender clustering. Their overall goal was to use the study to fill in some important knowledge gaps about the issue of sex-offender residential clustering in order to inform the development of effective policy. To examine this issue on behalf of the city council, we relied on a multi-methodological research design. We wanted to incorporate information from several different points of view, giving policy makers a more comprehensive perspective from which to inform their decision making. For this study, we relied on four resources: official police data, offender interview data, citizen survey data, and key stakeholder interview data.

Concern has been expressed that mesquite bosques are disappearing or diminishing in quality, and that the survival of the mesquite mouse is consequently threatened. This study, funded by a grant from the Arizona Heritage Fund to the Pima County Regional Flood Control District, investigated the current distribution of the mesquite mouse by reviewing historical records from museum specimens, examining existing potential habitat at historic locations of the species and elsewhere in the county, and conducting a live-trapping study at 19 sites representing a range of ecological communities with mesquite as a major component.

The South Mountain neighborhood is located in the southern part of the City of Phoenix in Maricopa County. The three zip codes of 85040, 85041 and 85042 comprise the bulk of the neighborhood and serve as the target area boundary for this report. South Mountain is a distressed community, with significant need and limited resources. It is an area that differs from most of the city, with a pre- dominantly economically disadvantaged Latino and African-American population. As part of Maricopa County’s efforts to identify the needs, the gaps in services and resources, and to use data to inform the County about making effective and meaningful policy changes, this report uses data collected as part of the ongoing AARIN project and economic measures derived from U.S. Census data to help examine and potentially guide restoration efforts in South Mountain.

Phoenix Sky Harbor International Airport completed a comprehensive analysis of the cargo service opportunities of Phoenix metropolitan airports, specifically Phoenix Sky Harbor International, Phoenix Deer Valley, Phoenix Goodyear, and Phoenix Mesa Gateway Airports. The Study researched regional air cargo opportunities, forecasted regional air cargo demand, determined necessary facilities and infrastructure at Phoenix region airports, identified market opportunities and outlined approaches for further development.

In fiscal year 2012, Isaac Elementary School District’s student achievement was similar to peer district averages, and the District’s operational efficiencies were mixed, with much higher administrative and plant operations costs than peer districts’ averages but lower food service costs. Between fiscal years 2007 and 2012, the District decreased its classroom spending while it increased nonclassroom spending, primarily for administration and plant operations. At the end of fiscal year 2011, the District closed two schools to reduce costs, but its administrative and plant operations costs remained high, partly because of higher staffing levels. The District’s transportation program operated efficient bus routes but had much higher costs per mile and per rider than peer districts’, partly because it operated a smaller program but also because it offered more generous benefits. Finally, the District lacked adequate controls over user access to its computer network and systems.

In fiscal year 2012, Fowler Elementary School District’s student achievement was slightly higher than the peer districts’ averages, and the District operated efficiently. The District’s administrative cost per pupil was similar to the peer districts’ average, and it employed proper accounting and computer controls. The District’s plant operations costs per pupil and per square foot were lower than the peer districts’ averages primarily because of lower energy costs. Additionally, the District’s food service cost per meal was lower than the peer districts’ average, and the program was self-sufficient, in part, because the District paid the vendor that ran its program lower administrative and management fees than peer districts, on average. Further, the District’s transportation program was efficient, with lower costs per mile and per rider and efficient bus routes. However, the District did not accurately report its number of riders transported, which resulted in substantial overfunding for fiscal years 2011 through 2014.

The list was compiled by the Department of Water Resources in cooperation with the Landscape Technical committee of the Arizona Municipal Water Users Association, comprised of experts from the Desert Botanical Garden, the Arizona Department of Transportation and various municipal, nursery and landscape specialists. Individuals wishing to add or delete plants from the list may submit information to the Director of the Arizona Department of Water Resources for consideration.
