(a) Buildings on the National Register.
(b) Contributing resources in a registered historic district, i.e., buildings, sites, structures and objects filed as such with the National Register of Historic Places.
(c) Buildings, sites, structures, objects and districts which have received a determination of eligibility (DOE).
(2) Class II. Historic resources and districts not meeting National Register criteria, but determined to be of historical significance (for example, more than 100 years old or related in some way to an important person or significant to local history) to Delaware County and/or Concord Township and appropriately documented to that effect by the Concord Township Historical Commission.
(3) Class III. Historic resources and districts included in the Historic Resources Map of the Historical Commission and not included in either Class I or Class II above.
B. Revisions. The Historic Resources Map shall be reviewed as needed but at least once each calendar year and revised if needed by legislative action of the Township Council, after a public hearing.
(1) In considering any revisions, including additions, deletions or changes of classification to the Historic Resources Map, the Township Council shall afford the Historical Commission an opportunity to supply a written recommendation.
(2) The owner(s) of any property(ies) which is the subject of any such proposed legislative action shall be given written notice of the Historical Commission's recommendation to the Township Council at least 30 days prior to the public hearing.
C. Official inventory. The Historical Commission shall maintain an updated inventory of resources shown on the Historic Resources Map and their respective classifications for Concord Township.
