About this map

Big Mountain and Oak Ridge define the high terrain of this portion of Ventura County, where the valley floor transitions from agricultural use to suburban expansion. The 1969 revisions, indicated in purple, highlight the rapid residential growth of Simi and Moorpark during the post-war era. Infrastructure like the Southern Pacific railroad and the Rejada Road serve as the primary conduits through the Little Simi Valley.

The landscape is heavily marked by the region's petroleum industry, with extensive operations visible at the Big Mountain Oil Field, Oakridge Oil Field, and Simi Oil Field. Cultural development is evident in the establishment of Moorpark College and numerous local schools such as Royal High Sch and Berylwood Sch. Water management is central to the area's geography, with the Arroyo Simi and Arroyo Brea draining the rugged canyons that cut through the hills.
