General Contractor Santa Paula

The area of what today is Santa Paula was inhabited by the Chumash, a Native American people, before the Spanish arrived. In 1769, the Spanish Portola expedition, first Europeans to see inland areas of California, came down the Santa Clara River Valley from the previous night’s encampment near Fillmore and camped in the vicinity of Santa Paula on August 12, near one of the creeks coming into the valley from the north (most likely Santa Paula Creek). Fray Juan Crespi, a Franciscan missionary traveling with the expedition, had previously named the valley Cañada de Santa Clara. He noted that the party traveled about 9 to 10 miles (14 to 16 km) that day and camped near a large native village, which he named San Pedro Amoliano. The site of the expedition’s arrival has been designated California Historical Landmark No. 727.

Franciscan missionaries, led by Father Junipero Serra, became active in the area after the founding of the San Buenaventura Mission and established an Asistencia; the town takes its name from the Catholic Saint Paula. Santa Paula is located on the 1843 Rancho Santa Paula y Saticoy Mexican land grant.

In 1872 Nathan Weston Blanchard purchased 2,700 acres (10.9 km²) and laid out the townsite. Considered the founder of the community, he planted seedling orange trees in 1874. Several small oil companies owned by Wallace Hardison, Lyman Stewart and Thomas R. Bard were combined and became the Union Oil Company in 1890.
