Preservation Plans

Preservation Plans are documents that guide the preservation of historic resources by establishing goals and recommending implementation measures.


Cities adopt Ordinances to help provide legal guidelines for making decisions regarding the future of our historic resources.


Historic Resource Surveys are used to inventory the historic resources within the County.


Photographs are one method of documenting a landmark’s past, as well as showing a landmark’s current condition.

Educational Videos New

Cultural Heritage Board guest speaker sessions highlight local scholars and voices related to the disciplines of architecture, history, architectural history, planning, archaeology, or other historic preservation-related disciplines, such as urban planning, American studies, American civilization, cultural geography, or cultural anthropology. These sessions are consistent with the Cultural Heritage Program goal of helping to foster an awareness and appreciation of Ventura County’s rich history and variety of cultural resources among both residents and visitors.
