Urban development should be guided by a sustainable planning and management vision that promotes interconnected green space, a multi-modal transportation system, and mixed-use development. Diverse public and private partnerships should be used to create sustainable and livable communities that protect historic, cultural, and environmental resources. In addition, policymakers, regulators and developers should support sustainable site planning and construction techniques that reduce pollution and create a balance between built and natural systems.
New sustainable urban developments or re-developments should provide a variety of commercial, institutional, educational uses as well as housing styles, sizes and prices. The provision of sidewalks, trails, and private streets, connected to transit stops and an interconnected street network within these mixed-use developments provides mobility options and helps reduce pollution by reducing vehicle trips. Walking, bicycling, and other mobility options should be encouraged throughout the urban mixed-use core and mixed-use neighborhoods with easily accessed and well-defined centers and edges.
