In the latest stumble for plans to build a massive $2.8 billion dam in Southern Santa Clara County near Pacheco Pass, a judge has ruled that the Santa Clara Valley Water District violated state environmental laws over the dam’s preliminary geological work.

The ruling could lead to further delays in the proposal to construct the largest new dam in the Bay Area since Los Vaqueros Reservoir in Contra Costa County was built in 1998.
