San Francisco city planners have approved a $1.5 billion neighborhood to be built on Treasure Island, located in San Francisco Bay between the city and Oakland.
The plan includes 8,000 residential units and a 450-foot high-rise on the island.
Critics say the man-made island would not fare well in an earthquake and that the project would increase traffic on the San Francisco-Oakland Bay Bridge.
Supporters say developing the 400 acres in the middle of San Francisco Bay is a unique opportunity.
San Francisco's Planning Commission voted 4-3 on Thursday. It will next be considered by the Board of Supervisors.
