A comprehensive Masterplan for the mixed-use development of a 315-acre site south of downtown San Francisco, the project is located along the waterfront, creating a new district on land formerly owned by the Southern Pacific Railroad. The centerpiece of the plan is an integrated community that will become an economic and housing resource for the city. Approximately 8,000 residential units are planned to house people of varying incomes, including singles, families, and individuals with special needs. Mission Bay is a predominantly pedestrian environment, with parks and open spaces marking major commercial centers and providing view corridors and pedestrian connections to the waterfront and adjoining districts. When completed, Mission Bay will be one of the largest privately sponsored urban developments in California.
