Across America, billions of dollars are being invested in the built environment - specifically in housing and transportation. These investments determine the type of communities that we live in and the opportunities we are afforded. They are, as Rajiv Bhatia states it, "social policies in concrete." In this segment, we will argue that policies around the built environment are also "health policies in concrete." Dr. Richard Jackson will give us an overview of how investments in housing and transportation have deep implications for health equity. Dr. Rajiv Bhatia will offer housing, transportation, and health practitioners policy tools to improve the impact of planning and development decisions on community health. An example of an innovative partnership to build more transit oriented affordable housing will follow - The San Francisco Foundation Community Development Program Director Vanitha Venugopal will discuss The Great Communities Collaborative (GCC), the Bay Area's model transit oriented development network. A specific focus will be given to the GCC's instrumental role in catalyzing the Transit-Oriented Affordable Housing (TOAH) fund, a $50 million partnership public private partnership. Asian Health Services Director of Planning and Development Julia Liou will also highlight the innovative, neighborhood-level collaborations where health promotion has been at the center of their housing and transportation planning.
