2015 Map of San Onofre Bluff

About this map

The coastal boundary between Orange and San Diego Counties is defined by this coastal corridor, where the land meets the Pacific Ocean. This stretch of Southern California shoreline is characterized by the prominent San Onofre Bluff and the carved terrain of Foley Canyon. Transportation history is layered here along the narrow terrace between the hills and the sea, featuring both the historic El Camino Real and the Old Pacific Hwy. These routes follow the natural contours of the coast, connecting the settlement of Agra to the surrounding region. The map highlights the intersection of modern infrastructure and the geographic constraints of the coastal bluffs, documenting the alignment of the California state border and regional transit links during the mid-2010s.
