Demolition or removal of an historic or architecturally significant structure may be forbidden or postponed for up to six months from date of public hearing of the application. The planning board shall, during this hiatus, consult civic groups and public agencies to ascertain how the borough may preserve the building and/or premises. The planning board shall attempt with the owner to establish feasible plans for preservation of structures where moving or demolition thereof would be a great loss to the public and to the borough.

When it is appropriate and expedient to move an historic or architecturally significant structure to another site within the borough to preserve it, upon approval of the relocation plans by the planning board, said structure may be relocated providing it fulfills the area regulations of said zone as to lot size, set back and yard area.

The planning board shall issue a certificate of appropriateness upon approval of the application. A building permit shall not be issued until such certificate of appropriateness has been issued by the planning board.

In case of disapproval the planning board shall state its reasons therefor in writing and may make recommendations to the applicant with respect to appropriateness of design, arrangement, texture, materials and the like, of the building or structure involved.

Upon approval of the plans, the planning board shall cause a certificate of appropriateness, dated and signed by the chairman, to be issued to the applicant or affixed to the plans.
