In an ominous sign for an already struggling project, state officials on Wednesday said they are unhappy with the lack of progress over plans by the Santa Clara Valley Water District to build a huge new dam near Pacheco Pass and Henry W. Coe State Park in Santa Clara County. Members of the California Water Commission, an 8-member agency appointed by Gov. Gavin Newsom that tentatively committed $504 million in state bond funding seven years ago to the $2.7 billion project — and still could revoke it — expressed frustration at the district’s shifting timelines and lack of specifics and accomplishments. … On Wednesday, district officials told the water commission that they still haven’t secured major permits needed to start construction, haven’t secured water rights, and only have completed 30% of the design. They said they wouldn’t be able to break ground until 2029 and won’t complete construction until at least 2036.
