State contractors have readied plans to acquire as many as 300 farms in the California delta by eminent domain to make room for a pair of massive, still-unapproved water tunnels proposed by Gov. Jerry Brown, according to documents obtained by opponents of the tunnels.

Farmers whose parcels were listed and mapped in the 160-page property-acquisition plan expressed dismay at the advanced planning for the project, which would build 30-mile-long tunnels in the delta formed by the San Joaquin and Sacramento rivers.

“What really shocks is we’re fighting this and we’re hoping to win,” said Richard Elliot, who grows cherries, pears and other crops on delta land farmed by his family since the 1860s. “To find out they’re sitting in a room figuring out this eminent domain makes it sound like they’re going to bully us … and take what they want.”...

“If these reports are correct, then we have further confirmation that the tunnels project has been a forgone conclusion,” state Sen. Lois Wolk, D-Davis, who chairs a committee on the delta, said in an email Monday.
