Engineer: Twin Tunnels project could endanger vital levees

The proposed tunnel path stretches 35 miles from west of Elk Grove to just below Discovery Bay. The tunnels would take water from three intakes along the Sacramento River to existing aqueducts south of Discovery Bay, and then the water will be sent to Southern California. Along the proposed path, there are at least 22 levees that would sit above the tunnels….  The concern is not so much the levees themselves, but the kind of soil that is below the levees.

America’s second biggest levee system is keeping Sacramento dry — for now

Not long after the Gold Rush of 1849, California became a state and made its capital in Sacramento. It seemed a logical choice. The city was served by the two of the state’s biggest rivers, the Sacramento and American, at a time when a lot of goods and people moved via river traffic. It was somewhat centrally located. But, there was the occasional flood. Every spring, the snowcap in the Sierras melts, leaving a significant amount of water in the Central Valley, where Sacramento sits. The city engineered a levee system to control the seasonal flooding.
