Excerpt:

To cheers and applause from the audience, the Board of Supervisors unanimously approved a massive new neighborhood proposed for Treasure Island.

In the 11-0 vote the board rejected claims by groups such as the Sierra Club that the project would harm the environment and exacerbate traffic problems.

Instead, members of the board said the $1.5 billion project would breathe new life into the old Navy base in the middle of San Francisco Bay.
