The Southern Nevada Water Authority Landscape Awards Program wants to honor Las Vegas homes with beautiful, water-conserving landscapes. The annual Landscape Awards contest is one way to recognize owners of Las Vegas real estate who have the vision to promote water-efficient landscaping and still create a beautiful desert environment for their homes. The deadline for entering the contest is April 13. This is usually when most of the Greater Las Vegas landscapes are at their peak of color. The contest is open to all southern Nevada home owners who design and install water-efficient landscapes.
