The Regional Plan Association Healthy Communities Initiative, supported by the Centers for Disease Control, the Milbank Memorial Fund, and the Robert Wood Johnson Foundation, restores the historic relationship between the disciplines of town planning and health science. By doing so, the core of the regional design agenda - promoting development in mixed-use, pedestrian-oriented centers, remaking the suburban landscape to reduce auto dependency, and designing transit-supportive development - is seen not only as rational, sustainable, “smart growth,” but as a strategy for promoting active, healthy lives.
