Land uses delineated in comprehensive plans provide the foundation for city government and private actions that have a substantial long-term effect on whether our cities move toward carbon neutrality and energy efficiency or accelerate climate change and increase energy costs. And zoning districts defined in comp plans have substantial equity impacts and can, for example, inadvertently suppress housing choices. Land development decisions are infrastructural - once made, they are extremely difficult, expensive and slow to undo. Consequently, land use plans either enable other best practices and city goals, or hinder their effectiveness. In order to have public support and legal validity, land use strategies, zoning and regulatory ordinances must be grounded in a comprehensive plan. The process of developing and adopting a comp plan with embedded visions and goals is an essential community-building opportunity to engage community members in the clarification of community values and long-term aspirations. Some comp plans include energy and/or climate goals, and some cities produce separate energy plans and climate plans.
