California officials have released their latest plan to reroute water from the wetter north to the drier south through a giant underground tunnel

SACRAMENTO, Calif. -- A new plan to reroute how water moves from wetter Northern California to drier Southern California would ferry some of it through a single, 45-mile (72-kilometer) underground tunnel, wrapping around the state’s existing water delivery system and dumping it into the main aqueduct that flows south to vast swaths of farmland and millions of people.

It's scaled back from the two-tunnel plan championed by former Gov. Jerry Brown and the latest iteration of a project that has been talked about and planned in some form, but never constructed, for about half a century.

Still, even if the political support to build it is there, construction likely wouldn’t break ground until at least 2028 and would take more than a decade,

Water officials say the chosen path would have the least negative consequences of the various options. Still, the 10-year construction would require removing 71 buildings, including 15 homes, as well as overtaking 2,340 acres of farmland and running through cultural resources and sites significant to tribal communities, the report said.
