The original master plan envisioned three major business centers in Malaga Cove, Valmonte, and Lunada Bay, with minor business centers in Margate, Miraleste, and Montemalaga. The Lunada Bay Plaza area was originally going to be constructed at Via Mirola and was to be a grand plaza with several large buildings, but was ultimately constructed on a scaled down basis a bit north at Yarmouth Road.

The only business centers originally planned for the Palos Verdes Project which were constructed were at Malaga Cove, Lunada Bay, and Miraleste.

In addition to the early planned districts of Valmonte, Malaga Cove, Margate, Lunada Bay and Miraleste, located in the current City of Palos Verdes Estates,there were several other planned districts, now part of Rancho Palos Verdes, called "Telarana" (near the Point Vicente lighthouse), "Taravel" (near Long Point), "Cabrillo" (near Portuguese Bend) and "Altamira" (near the Peninsula Center shopping center).

Thanks for sharing the old pictures of Palos Verdes. I enjoy a drive in PV every now and then. Something magical about the air there that takes all your worries away if only for the day!
