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.

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.

Arizona has grown rapidly over the years and our education system has grown in step with the population. But increasing the total budget for education doesn't mean that we have directed more resources to each student. The numbers show that Arizona has one of the lowest per-pupil funding rates in the country. Parties of one faction or another argue endlessly about which numbers to use in comparing Arizona to other states, or even whether such comparisons are possible. What is indisputable is that Arizona ranks in the bottom tier of states in both education spending and in student achievement and that we have made substantial cuts in our funding of both K-12 and higher education since the beginning of the Great Recession.

The purpose of this brief report is to provide information about the past, present, and future of a very significant education reform program and tax increase, commonly known as Proposition 301. Coverage includes the history leading up to the ballot measure approved by Arizona voters in November 2000, its status approximately one year after it went into effect, and its prospects over a 20-year life span.
