The Yield And Reliability Demonstrated in Xeriscape (YARDX) project was a study of potential water savings and maintenance and installation costs associated with water conserving landscapes. The study was funded by the U.S. Bureau of Reclamation with in-kind services by seven participating municipalities and water districts along Colorado's Front Range. This final study report was completed in December of 2004 based on research conducted from 1997 to 2002 gathered through in-the-field demonstration sites (actual homeowners' yards). YARDX study sites incorporated a xeriscape design and installation which yielded, with a few exceptions, water savings ranging from 18 to over 50 percent.
