The purpose of the Arizona Trails 2015 Plan is to gather information and recommendations to guide Arizona State Parks and other land management agencies in the management of motorized and non­‐motorized trails, and guide the distribution and expenditures of the Off‐Highway Vehicle Recreation Fund and the Federal Recreational Trails Program. The Arizona Trails Plan is updated every five years.

This planning document details the results of extensive surveys of Arizonans’ thoughts, preferences and priorities regarding trails and off-highway vehicle routes. Throughout the year 2008, staff at Arizona State Parks and faculty at Arizona State University partnered to solicit information from more than 5,500 Arizonans about what types of motorized or non-motorized trails they use, how often they use trails, what they like or don’t like about trails, and what trail managers should focus their time and dollars on to make the trail experience better.

The report states that the State Parks system is in imminent danger of complete collapse as a result of financial starvation during most of this decade. A chronic lack of capital funding has led to the devastation of Parks infrastructure. In addition, budget cuts in Fiscal Years 2009 and 2010 so far have forced the closure of several parks and reduced hours at 17 other sites. The Task Force's chief recommendation is that the State should implement a Sustainable State Parks Fund, which would be financed by a $14 to $15 annual contribution to be collected from owners of non-commercial vehicles as a part of the vehicle registration process. The proceeds would be dedicated to the operation, maintenance and capital needs of State Parks. In return, private vehicles bearing Arizona license plates would be admitted free to State Parks.

As Arizona’s population continues to grow, so does the need for electricity. Retail sales of electricity in Arizona have increased along with the population, although sales per person have declined since peaking in 2007, a sign of decreased use and increased efficiency. As we progress in the twenty-first century, action must be taken to increase the sustainability of our energy resources by continuing to conserve and by shifting to the greater use of energy from renewable sources. In addition, we must work to mitigate climate change by reducing greenhouse gas emissions.

Both the effect of climate change on our future water supply and the size of the population that will need to share in that supply are uncertainties that water planners must consider when making decisions regarding our future. We have options, but we have to be sure that we use water efficiently to meet our urban, agricultural, and environmental needs. This Policy Points offers a clear, succinct overview of the status of Arizona’s water supply and what the current drought really means for water availability.

In a desert city such as Phoenix, summertime heat is a way of life, but how much does the built environment contribute to the intensity of the heat on a summer night? In urbanized Phoenix, nights don’t cool down as much as in the surrounding rural areas and on more and more summer nights, the official Phoenix temperature fails to drop below 90 degrees. Climate plays a huge role in the comfort and quality of life of residents, with numerous implications for tourism, energy demand, water use, and the vulnerability of low-income families.

During the mid-part of the last decade, when the population growth rate was at its highest, the Phoenix area experienced rapid development and urban sprawl. The result has been an intensification of the Urban Heat Island effect. In this edition of Decades, author Sally Wittlinger discusses this uncomfortable consequence of urbanization.
