Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Laguna Hills’ 0.0 sits below most of its state (31% of California towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

The story

How Laguna Hills came to be

From Wikipedia’s history of Laguna Hills.

Read it all →

Laguna Hills is built on one of the major land grants developed during the rancho era. Following Mexico's independence from Spain in 1821, those who had served in the government or who had friends in authority, were given vast lands for cattle grazing. Rancho Lomas de Santiago, Rancho San Joaquin, and Rancho Niguel covered much of the western portion of the Saddleback Valley. Don Juan Avila was granted the 13,000-acre Rancho Niguel on which Laguna Hills is located.
