Here’s an overview of how the “new” Single Tunnel Plan is the same as the old plan. And what is different (not much).
The only difference is a possible new Eastern route which goes a bit more around-the-Delta than through it. But other than a swath of purple on a map, there are no details yet about construction impacts with an Eastern tunnel route.
Otherwise, the same construction impacts exists at the North intakes and along the old Through-Delta route (still an option). In addition, regardless of tunnel route, the construction will leave behind muck in the Delta plus the same long-term water quality issues exist.

So important to have these solid details. I can only fix on the permanent loss of exported CA soil mineral and ag produce-embedded water to foreign agribiz and stewart & lynda resnick, with no profit-sharing plans between them & agribiz, and CA citizens.
