When the TJPA was created over 20 years ago, it was charged with delivering the Transbay program, a long-term vision of economic vitality in downtown San Francisco. The program consisted of three elements: operating a world class Salesforce Transit Center; creating a transit-oriented neighborhood; and extending rail into downtown San Francisco. Of the three elements of the Program, TJPA has delivered on two: the multimodal Transit Center and rooftop Park and creation of a vibrant neighborhood featuring open spaces, businesses and housing (35% are affordable) and now, it is focused on delivering the Portal, also known as the Downtown Rail Extension project (DTX).  Over the last decade, this neighborhood has seen the creation of a transit-oriented neighborhood featuring housing, open space, offices and shops surrounding the Transit Center.
