Some residents of drought-stricken California who let their lawns turn brown and took shorter showers could soon get some relief, while others may continue to feel the pain.

The challenge for state regulators will be treating millions of residents fairly, unlike the El Nino storms that soaked Northern California with considerably more rain and snow this winter than the drier Southern California.
