The Arizona Smart Growth Scorecard is a tool for community self-assessment developed by a working group of the Growth Cabinet. It is designed to strengthen the ability of local officials to plan for future growth and development and to adopt comprehensive strategies that address growth-related pressures.

The Guiding Principles are organized into six major categories which provide the basis for the Scorecard: responsibility and accountability; preservation of community character; stewardship of natural resources; opportunity for broad choices; essential service infrastructure; and economic development.
