Clifford Heights, once known as Rattlesnake Hill, but more commonly known today as Palomar Park, is well known for its strong sense of community. The Palomar Property Owners was established in 1956, and residents work to maintain roads, fences, and community property in the neighborhood. They also hold social events, such as an annual neighborhood picnic. Palomar Park borders Cordilleras Heights and offers similar hilly terrain and luxury homes on large lots. There are less than 1,000 residents and 300 homes in this secluded, woodsy borough.
