History
The Nipomo Mesa lies within the ancestral homeland of the Northern Chumash, also known as the Obispeño, who have lived in the region for more than 10,000 years and who traded shell beads and fine-grained tool stone between coastal and interior villages.[6] Archaeological survey of the mesa has recorded prehistoric camps and villages along the tops of the bluffs and the older dunes, with further sites inland near springs and along Black Lake Canyon, where large, low-density settlements have been documented.[7]
The San Luis Obispo County Board of Supervisors adopted the Black Lake Specific Plan on February 28, 1983. The plan provided for residential and recreational development centered on the golf course.[5]
In December 2025, the Board of Supervisors voted to allow an application for a plan amendment proposing 125 additional units, including homes, lodging, and short-term rental accommodations. The vote authorized the application process; it did not grant final approval for construction.[8]
