The Georgetown, Texas City Council voted unanimously on Tuesday night to limit the size of new lawns that can be watered.
The new ordinance says that the size of a new lawn, which receives water, can only be two-and-a-half times the size of the home's foundation or 10,000-square-feet, reports KVUE.
The new rule also requires that native drought-resistant plants must be part of the landscaping for new homes.
The size of the actual yards is not affected, only the part that people use water on.
The so-called "lawn law" came about because of the brutal drought the state has had to endure. Another factor is that 75 percent of the city's water use is directed at lawns during the summer.
“Right now, we have enough water to meet the current demand, probably enough for the demand for a while, the issue is we are at about 56,000 that our water utility serves and we are projected to go to 200,000, and if we use at the current rate, we will not be able to meet that future demand,” city of Georgetown spokesman Keith Hutchinson told My Fox Austin.
Lake Georgetown is the main source of drinking water for residents, but without some serious rain the lake may only be half full by the end of the month.
