Alteration of rock outcrops
The City Planning Commission may authorize the alteration of a rock outcrop, provided that:
(a) the development or enlargement is not feasible without such alteration, or that the requested alteration will permit a development or enlargement that satisfies the purposes of this Chapter; or
(b) such alteration is necessary to protect the health and safety of the site occupants; and
(c) such development or enlargement, as authorized, will result in the minimum natural feature interference that must be permitted in order to allow reasonable development or enlargement and bulk distribution under the regulations of the underlying district.
The Commission shall impose appropriate conditions and safeguards to assure protection of the portions of the area to be preserved in their natural state.
