Developers are required to utilize low-water landscaping materials designed for our semi-arid environment. There are very specific requirements for landscape materials and irrigation practices and the landscape criteria manual (PDF) is updated periodically. For example, Kentucky Bluegrass is not allowed on common spaces and, in 2018, it is no longer allowed anywhere for new development in the Town - including on residential lots.
While we are high, mountain desert, we don't call it desert-scape. We don't even call it xeriscape. These terms give the idea of rock and cactus. While beautiful, this is not the native Colorado landscape. Castle Rock advocates "ColoradoScape," which emphasizes landscape design with a variety of colorful, low-water-use plants, accented by boulders and filled in with various organic mulch.
