As of June 10, 2022, a new state regulation bans the irrigation of decorative or non-functional grass with potable water in commercial, industrial and institutional settings. The regulation applies to turf that is ornamental and not used for recreation. It does not apply to residential lawns, school fields, sports fields, or areas regularly used for civic or community events.
According to the State Water Board, ending irrigation of non-functional grass will save the equivalent of water used by as many as 780,000 households every year. The regulation does not restrict the watering of non-turf plantings or trees, which are important for shade and cooling as the state experiences more extreme heat events.
