Street access, building design, off-street parking, landscaping, and buffering guidelines. The Planning Board shall, in its site plan review of applications, consider street access, building design, off-street parking, landscaping and buffering for all new construction and expansion of existing buildings in the Fifth Avenue Overlay Zone. In accordance with existing regulations, site plan approval is required prior to the issuance of a building permit for the construction or enlargement of any principal use and prior to the issuance of a certificate of occupancy for any change of use or occupancy, which would result in an increase in the requirement for off-street parking or loading spaces and for any parking lot created or altered in accordance with the provisions of Article
XIV of this chapter. The Planning Board is authorized, in its sole discretion in exercising site plan approval authority, to require that buildings not be set back greater than five feet from front property lines along Fifth and Potter Avenues; to prohibit curb cuts and driveways and to require the underground siting of on-site utilities of all properties fronting on Fifth and Potter Avenues; to require additional buffering, landscaping, and screening for all properties in the Fifth Avenue Overlay Zone; to require additional architectural detailing, mansard roofs, and fenestration (albeit faux) of building facades that front Fifth and Potter Avenues; to restrict loading and delivery areas along Fifth and Potter Avenues; and to permit alternate locations for required off-street parking facilities in accordance with §
331-126E(3) herein. The Planning Board may also reduce the total number of off-street parking and loading spaces required for all properties in the Fifth Avenue Overlay Zone, where the applicant demonstrates to the satisfaction of the Board that the capacity of a shared-use facility will satisfy the purposes of this zoning ordinance by reason of variation in the probable time of maximum use by visitors, patrons, deliverers and/or employees.
