Las Vegas Ripping Up Lawns to Save Water, But is it Enough?

In an effort to reduce water usage, in 1999 Las Vegas began to offer $1.50 per square foot of lawn removed from residential and commercial properties. The Water Smart Landscapes program estimates that every square foot of grass replaced with water-smart trees, shrubs and flowers saves an average of 55 gallons of water per year, also saving money on monthly water bills. In the first eight years of the measure, about six square miles of grass have been eliminated, saving 18 billion gallons of water.

Despite these efforts, if Las Vegas does not further cut water usage, there is a 10 percent chance that Lake Mead will run dry in six years, and a 50 percent probability it will be completely gone by 2021, absent other changes. These figures are based on a recent study by two researchers at the Scripps Institution of Oceanography at the University of California San Diego.
