Scientists question twin tunnels report

An independent team of scientists renewed its criticism of Gov. Jerry Brown’s twin tunnels plan this week, saying that the massive documents justifying the project are “incomplete and opaque.”

The Delta Independent Science Board isn’t judging whether the $15 billion tunnels are a good idea or a bad idea.

Rather, the board is criticizing the environmental documents that are supposed to explain — to experts and the general public — what benefits the tunnels would provide and what impacts they might have.
