HistoryA character grade: shown, never part of Encinitas’ overall grade.
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 Encinitas’ 2.1 sits above most of its state (81% of California towns have fewer) while its 13 historic buildings outnumber those of 77% of U.S. towns.

What stands out about Encinitas’ past
Read from the archive, the National Register and the record. The page puts what stands out first.
Gaspar de Portolá, governor of Baja California, met the indigenous Kumeyaay people when he visited the area in 1769 on the Portolá expedition and he met residents from the nearby Kumeyaay village of Jeyal (or Heyal), near the San Elijo Lagoon. Portolá named the valley Los Encinos for the oak forest along El Camino Real, where there was also a village that was likely known as Hakutl in New Encinitas.
After Mexican Independence, land was granted to Andrés Ybarra in 1842 to build Rancho Las Encinitas in what is now Olivenhain and New Encinitas, from which Encinitas got its namesake. Encinitas is a Spanish name meaning "little oaks".
The town of Old Encinitas was formed in 1881 by Jabez Pitcher.
