LANDSCAPING The site design preserved 70% of the lots existing vegetation such as black sage, indigo, and creosote. The small amount of watering that is required for the yards drought-tolerant plants and treesincluding prickly pear, yucca, and Arizona rosewoodis controlled via a Rainbird drip irrigation system. Instead of turf, permeable crushed sandstone covers the ground and chat, a type of crushed granite, is used for planting beds instead of mulch. 800.724.6247. www.rainbird.com.
