State officials said this afternoon that the so-called “portfolio plan” proposed by some environmentalists and water agencies is “not a viable solution.”
Read Secretary for Natural Resources John Laird’s letter today (linked to within BDCP blog entry) to the San Diego County Water Authority, and its accompanying analysis.
In a nutshell, a smaller 3,000-cfs tunnel would be $6 billion cheaper than the 9,000-cfs twin tunnels, but would deliver less water, resulting in more costs than benefits in the long run. the state says.
Laird’s deputy, Jerry Meral, is expected to discuss the twin tunnels plan with the skeptical San Diego authority at a meeting Thursday, along with dueling economists David Sunding and Jeff Michael. Agenda and packet available here.
