The drought is over, but Sacramento water officials want to make permanent some of the region’s most restrictive lawn watering rules. The Department of Utilities wants to change the city code to allow sprinkler system watering two days a week during the summer, down from three in typical rainfall years. It will also increase the fines for a second violation of the rules from $25 to $50.Sacramento has kept its twice-weekly drought restrictions in place while other cities have eased rules. The plan, which a City Council subcommittee will consider on Tuesday, isn’t just about slashing water use.
