(1) The commission shall determine and periodically revise priorities for the identification and evaluation of historic resources.

(2) Unless the commission finds extraordinary historic importance, only properties over 50 years of age shall be considered for inclusion in the inventory of historic resources.

(3) The commission shall develop or adopt a system, based on historic integrity and significance, by which historic resource surveys are conducted. Historic resource surveys are necessary to maintain the inventory of historic resources, which lists, describes, and determines the eligibility of historic resources for listing in the designated landmark register. Not all properties listed in the inventory of historic resources are eligible for listing in the designated landmarks register. Listing in the inventory of historic resources is not a prerequisite to being nominated to the designated landmarks register. Historic resource surveys shall rank surveyed historic resources as eligible/significant (ES), eligible/contributing (EC), noncontributing (NC), or not in period (NP). Owners of surveyed properties will be notified of these findings.

(4) Documentation of properties in the inventory of historic resources shall be on forms compatible with the statewide inventory of historic properties, and within six months of completion, copies of the forms shall be supplied to the SHPO.

(5) Records concerning archaeological sites shall not be made available to the public. (Ord. 2051 § 1, 2021)
