Do the emergency water regulations affect trees?

The regulation does not restrict the watering of trees, just turf. Watering based on the specific needs of a tree is encouraged. The California Water Board urges people to continue to water trees, even while reducing or stopping the irrigation of turf. Trees that are just getting established may need to be watered more frequently, including hand watering. Trees near or on non-functional turf could be impacted by some responses to the ban on turf irrigation, but the regulation allows continued irrigation of trees even if turf, such as turf under trees, will receive water. See Watering Trees in Turf and the California Water Board's Save Our Trees website.

Where can I find information on the California Water Board's water conservation emergency regulations?

You can find updated documents and subscribe to announcements on the California Water Board’s Water Conservation Emergency Regulations website. There are two active regulations listed on the website.

The California Water Board has also published a set of frequently asked questions about the new regulations, and these questions-answers are copied from their page.

When did the emergency water regulations take effect?

The emergency regulation went into effect on June 10, 2022 and will remain in effect for a year, unless modified or extended.

How is "non-functional turf" defined?

Turf is “a ground cover surface of mowed grass.” Non-functional turf is solely ornamental and not regularly used for human recreational purposes or for civic or community events. It does not include school fields, sports fields, and areas regularly used for civic or community events.

Are there exceptions to the ban on watering non-functional turf?

Yes, the irrigation ban applies only to non-functional turf in the commercial, industrial, and institutional sectors (not residential) and only applies to the use of potable water for irrigation. Irrigation of turf used regularly for human recreational purposes is allowed. Most importantly, the regulation does not ban the irrigation of trees or other non-turf plantings. Recycled water and grey water can be used to irrigate turf, however, the California Water Board prioritizes the irrigation of trees due to the severity of the drought. There is also an exemption process for certain low-water turf species and irrigation approaches.

What plants does the California Water Board prioritize?

Trees! Our trees are an investment. It will take more water, time, and money to replace a tree lost in drought than it does to keep it alive.
