While Palm Canyon is a natural oasis, with a constant water source, the city of Palm Springs and the entire Coachella Valley is not. Billed as a Golf Capital of the World, the Palm Springs tourist bureau touts over 100 golf courses in an area that receives about 5 inches of rain a year!
In addition most of the homes have grass in their lawns. As a result it is a very lush place during a time of long term drought.
Palm Springs has for decades been a winter escape for the wealthy, with many building the signature mid century modern homes back in the 1940s and 1950s. Most of those homes have been remodeled and sell for very high prices today.
Fortunately many of the remodels have taken the xeriscape approach and removed the grass in the landscaping.
