Friday’s top of the scroll: California eyes $10.6 billion cost for water tunnel

“State water officials said Thursday it could cost $10.6 billion to send water to Southern California through a proposed project of tunnels under the Sacramento-San Joaquin Delta.

The Department of Water Resources presented the cost estimate to a group of state and federal agencies studying ideas to safeguard water deliveries from the delta.

Two tunnels, about 150 feet underground, are being considered as an alternative to building a proposed canal around the fragile estuary. A third tunnel would serve as an intake tunnel, completing the 43-mile path under the delta.

Jerry Johns, DWR deputy director, described the cost as preliminary and said more design work needs to be done over the next year.

“I think it’s so preliminary at this stage, it’s hard to take the numbers seriously,” said Ann Hayden, a water expert at the Environmental Defense Fund. “The potential is there but we have a long way to go.” … “

    These estimates fit with earlier estimates given although I expect the costs to change as more detailed analysis is taken of the different routes.

    I think slide 17 is one of the more important slides. It gives construction pros and cons including risk levels for engineering and known/expected issues.
