The Mission Bay neighborhood is built on a landfill located on San Francisco Bay south of Townsend Street, east of Interstate 280, and north of Mariposa Street. The new UCSF research campus at Mission Bay is part of the rapid growth of a new neighborhood of office buildings and luxury condominiums being built in an area that was formerly an industrial area dominated by rail yards. The Dogpatch neighborhood lies to the south of it.
Formerly a salt marsh and lagoon, this redeveloped neighborhood has blossomed into a lively mixed commercial neighborhood filled with biotech companies, hospitals, and high-rise luxury condominiums. With good access to public transportation and entertainment, this neighborhood appeals to both singles and empty-nesters.
