2012 Map of Santa Rosa Hills

About this map

Rancho San Julian and Rancho de los Llanitos reflect the enduring legacy of the ranching era within the central coastal ranges. This landscape is defined by the high ridges of the Santa Rosa Hills and the southern reach of the Santa Ynez Mountains, where the drainage patterns of numerous creeks like El Jaro Cr, Ytias Cr, and Alamo Cr carve through the terrain. The northern boundary is shaped by the Santa Ynez River, which passes through the Lompoc Valley and beneath the Santa Rita Hills. The topography illustrates a complex network of canyons and arroyos, such as Arroyo El Bulito and Gaviolito Cr, which descend from the highlands toward the coastal plain. Rural access is maintained via historically-rooted routes like Sweeney Rd and Santa Rosa Rd.
