About this map

The Pacific Ocean coastline dominates this 2018 survey, where the terrestrial landscape is narrowly confined to the corridor along the Orange Co San Diego Co boundary. The topography is defined by the steep marine terrace of the San Onofre Bluff, where the land drops sharply toward the shore. Inland, the terrain rises into the coastal hills, notably around Foley Canyon, creating a compressed zone of transit between the highlands and the sea.

Transportation infrastructure follows this thin strip of land, with the historic route of El Camino Real and the Old Pacific Hwy running parallel to the modern interstate corridor. Near the southern edge of the sheet, the settlement of Agra sits along these primary transit lines. Recreational access is noted via the Bluff Top Trl, which traces the edge of the terrace, offering a perspective on how this coastal shelf has been utilized for both passage and preservation at the start of the twenty-first century.
