Critics and a California lawmaker want more answers from Gov. Jerry Brown’s administration on who’s paying for a proposed giant water project.That’s after a Southern California water district said Thursday that Brown’s administration is now stating that state or federal funds will be used to finish planning for two $16 billion water tunnels. The 35-mile-long tunnels would carry water from Northern California south, mainly for Central and Southern California. Brown’s administration is pushing to get regulatory approval for the tunnels before he leaves office in two years.
