Site Plan Review: Purpose. The Business District Site Plan Review Process and the issuance of Site Plan Approval endorsement is intended to protect the aesthetic and historic appearance of the Business District, promote economic development, protect property values and reduce traffic safety hazards and assure the proper design and construction of drainage facilities, parking areas, lighting, loading, waste removal, points of vehicle access and egress, pedestrian access, landscaping and screening. No building permit shall be issued in any case where site plan review is required and no area for parking, loading or vehicular service (including driveways giving access thereto) shall be established or substantially changed except in conformity with a site plan bearing an endorsement of approval of the Site Plan Approval Authority (SPAA). The Zoning Board of Appeals shall be the SPAA. The Zoning Board of Appeals may adopt rules relative to the issuance of a Site Plan Approval endorsement.
