2018 Map of Tres Pinos

About this map

Hollister anchors the western edge of this landscape, where the residential grids of the city transition into the productive agricultural lands of the Hollister Valley. The terrain rises sharply to the east into the Diablo Range, defined by the deep contours of Arroyo Hondo and the prominent Swanson Bluff. This 2018 survey captures the interface between modern development in Ridgemark and the older agricultural character of the Santa Ana Valley. The San Benito River and Tres Pinos Creek snake through the valley floor, providing the primary drainage for the surrounding Diablo Hills. Small-scale aviation history is noted at the Christensen Ranch Airport near the northern boundary, while the historic settlement of Tres Pinos sits at a strategic junction where the creek and river corridors converge. The map provides an exacting look at the modern road network, from major arteries like Santa Ana Valley Rd to the suburban street names on the Hollister fringe.
