Since 2009, HUD, DOT, and EPA have been coordinating their work to help communities around the country better meet their housing, transportation, and environmental goals--laying the groundwork for an economy that provides good jobs now and creates a strong foundation for long-term prosperity. This report describes accomplishments of the Partnership and the communities it serves on its third anniversary. American communities face complex challenges as they try to strengthen their economies, meet changing demand for housing and transportation, and protect the environment and public health. The Partnership agencies recognized they could better help communities by partnering to develop, implement, and share successful approaches. Small towns, suburbs, cities, and entire regions are planning for sustainable communities, and many have asked the Partnership to help them turn these plans into reality. Every region has different needs and resources, so communities are taking different paths to becoming more economically and environmentally sustainable and ensuring that all members of the community benefit from those improvements. One of the Partnerships goals is to help communities engage all residents in developing visions and plans for future growth. This inclusive planning catalyzes public and private investment and can speed implementation of plans.
