The Wave Basin will use about 78 acre-feet of water per year, compared to a golf course’s use of approximately 1,000 acre-feet per year. (One acre-foot equals 325,851 gallons, or enough water to cover an acre of land, about the size of a football field, 1 foot deep.) Therefore, the Wave Basin will use approximately 8% of the water used annually by a typical golf course. Coral Mountain will use non-potable water for the Wave Basin. Coachella Valley Water District (CVWD) provides further details on recycled and non-potable water use at golf courses on its website.
Unlike a golf course, the Wave Basin holds water and is primarily affected by evaporation.
CVWD used its established evaporation factors to calculate the evaporation rate for the Wave Basin, as explained in detail in the Final Environmental Impact Report. While the project’s water use has been deemed sustainable, Coral Mountain has taken additional steps to recognize the importance of water conservation. This includes a decrease in the size of the Wave Basin by one-third, elimination of ornamental water features, and commitment to a La Quinta-wide turf reduction program, as explained above.
