Home builders focus on low water-use features.

As Las Vegas keeps on growing, it's also looking far and wide for new water sources. There are designs to pipe water from counties north of here, but those counties are unhappy about that. Focus Property Group, a local home builder, is doing something about it on the conservation side. Its outdoor designs minimize yard sizes and the company installs irrigation systems that sense moisture and don't over-water. It also encourages desert landscaping by providing demonstration gardens at its developments where homeowners can get ideas and tips.
