A group of Northern California lawmakers seeking more sway over a mammoth $17 billion water project introduced a proposal Friday that would require new construction contracts to be reviewed by the Legislature. The Legislative Delta Caucus says because of the scope of the California WaterFix, the project should require more scrutiny from both the public and lawmakers now that former Gov. Jerry Brown has left office. Brown fiercely advocated for the expensive public works project that he and supporters believe will both update the state’s aging water delivery infrastructure and protect it against sea level rise and other effects of climate change.
