Lake San Marcos Community Association

Lake San Marcos is an unincorporated area of San Diego County, approximately 5 miles north of La Costa Spa and 7 miles east of the Pacific Ocean.  

In 1963, the Frazars purchased the property, raised the height of the dam, reshaped the shore line, and increased the lake’s size to its present 80 acres.  They subdivided the surrounding property and over the years condominiums and single family homes were built.

The uninterrupted Pacific breezes provide nature's air conditioning, with temperatures seldom above 80 degrees.  The Cerro de Las Posas mountain on Lake property and the San Marcos mountains to the north, with an eastern exit, create a wind tunnel preventing smog from settling in our valley.
