Californians could see their water bills increase under a measure passed by lawmakers Thursday. The legislative bill approved by the state Assembly would let local governments charge residents for storm water management systems without voter approval. Supporters of the measure say it will help cities and counties prevent flooding and save water. Opponents say it violates Californians’ right to vote on taxes. Gov. Jerry Brown must sign the legislation for it to become law. Under the bill, local governments could charge residents to construct storm water control facilities, which divert and store rain runoff.
