Around Las Vegas the gambling mecca, outsiders may wonder where all the grass has gone. Since 2003, no new home has been allowed to have turf in the front yard. After all, this is a city that may get 4 inches of rain a year. For older houses, the Southern Nevada Water Authority offers rebates to homeowners who rip out grass and replace it with water-smart landscaping, which means a lot of rocks and usually some cactus. Other cities in the West do the same.
Some people find it hideous, but many Westerners have come to embrace it. It may take Rich Leskovac a few more years to come around. "I love grass, and I won't change to desert landscaping. It's just not eye appealing to me. To me, it's rock," said Leskovac, who moved to Las Vegas from Greenville, Pa., five years ago.
In 2003, with the West in the thick of the drought, the Southern Nevada Water Authority shut down all decorative water fountains, leading to unsightly empty tanks outside gas stations and business parks. "Any visual use of water like that can undermine people's perception of water conservation. It gives you the impression that water's not valued in your community," said Doug Bennett, the authority's conservation manager. Attractions such as the Mirage volcano and the Bellagio fountains on the Las Vegas Strip are on, but only because they use low-quality ground water or recycled water.
In Southern California, a weekly watering index guides homeowners on how to use sprinklers more efficiently. It is based on a scientific formula that takes evaporation rates into account. Water-saving suggestions for the city of Anaheim, Calif., include taking quick showers and refrigerating drinking water rather than run the faucet until the water turns cold.
Western life is full of schedules that tell when you may or may not water a lawn. Water officials here and in cities such as Albuquerque, Denver, and Tucson enforce the rules. Deviate from the schedule, or allow water to run down the street, and you may find yourself with a ticket. In many cases, it's neighbors tattling on other neighbors. In Las Vegas, N.M., Trujillo has gotten calls from a number of anonymous homeowners in the middle of the night. The homeowners generally report something along these lines: "Mr. Trujillo, if you come out here now, you'll catch them."
