Permitted uses and dimensions

(a) Use of property located in an HPC zone shall be governed by the provisions of Table A—Permitted Use Table. Land or structures owned or leased by a nonprofit organization or corporation, or by the State of Rhode Island or one of its instrumentalities shall also require the preparation and approval of an institutional master plan (as hereinafter defined) and shall be deemed to be an "historic institution".

(b) It is the intent of this section and Table A to allow a variety of uses in existing buildings for historic institutions. It is also the intent to allow certain new construction on the grounds or "campus" of such historic institutions. However, in all cases, it is the intent of this section that permitted uses such as office rental, caretaker's residences, and waterfront uses, be incidental, subordinate and accessory to the principal historic institution.

(c) Specific dimensional requirements shall be the same as those identified in Table C—Dimensional Table for the R-40 zone. Dimensional requirements are hereby declared to be an integral part of the nature of the historic institution use and therefore any variance sought from the zoning board from dimensional requirements shall be deemed to be a use variance.
