If the Commission shall deem an improvement parcel appropriate
for the designation as a landmark, landmark site or historic district
and if the owner of the improvement parcel concurs in accordance with
the required poll, the Commission shall then call a public hearing
which shall be advertised in the official Town newspaper at least
15 days prior to the date of such hearing. A written notice of such
hearing shall be sent to the owner or owners of any property proposed
to be designated as a landmark or landmark site or placed within an
historic district. In addition, all owners of property adjoining the
proposed historic district, landmark or landmark site shall also be
notified.
Within 20 days following the adoption of a resolution establishing
a landmark, landmark site or historic district, such site or area
shall be so designated on the Official Map of the Town and will indicate
the portions of the land, if any, embracing the landmark, landmark
site or historic district.
A landmark, landmark site or historic district may be amended
or rescinded in the same manner as the original designation was made.
Any designation made under this chapter shall be in full force
and effect from and after the date of adoption.
