A. It is the intent and purpose of the board, by this chapter, to:
Preserve the county's historic and cultural heritage, as embodied and reflected in its historic resources;
Stabilize and improve property values and the local economy through the appropriate rehabilitation and reuse of historic structures;
Foster civic pride and increase the collective understanding of Napa's agricultural heritage and accomplishments of the past;
Protect and enhance the county's attractions to residents and visitors, and serve as a support and stimulus to business;
Protect the county's important assets and strengthen its overall economy; and
Promote the use of historic resources for the education, pleasure and welfare of the people of the county.
B. Toward the preceding goals, the county will promote citizen participation by:
Providing specific criteria for property owners who wish to designate their historic resources as Napa County Landmarks, thus making them eligible to apply for local, state and federal preservation incentives; and
Seeking funding, in kind donations, and volunteer efforts necessary to develop and maintain a comprehensive inventory of potentially eligible resources so that the State Historic Building Code may be utilized when applicable during rehabilitation, reconstruction or restoration activities.
