(a) All site lighting shall be designed so that the level of illumination as measured in footcandles (fc) at any one point meets the standards in the table below with minimum and maximum levels measured on the pavement within the lighted area and average level (the overall generalized ambient light level), measured as a not-to-exceed value calculated using only the area of the site intended to receive illumination.

(b) Exception for Gasoline Service Station Canopies: The average illumination on the pavement area under the canopy and around the fuel pumps shall be between thirty-five (35) and seventy (70) footcandles. The remainder of the gasoline service station pavement shall meet the requirements for high activity level parking lots.
(c) Exception for Bank and Credit Union Canopies: The average illumination on the pavement area under the drive-up canopy and around automated teller machines must meet federal regulations. The remainder of the bank and credit union parking lot pavement shall meet the requirements for high activity level parking lots.
(d) Architectural lighting shall be permitted as long as it is ground mounted near the building, utilizes seventy (70) watt or smaller lamps, and is approved by the Municipality's Division of Building, Zoning and Housing or its Architectural Board of Review.
(e) Lighting at Site Perimeter:
(1) The maximum level of illumination at the outer perimeter of the site or project is intended to be 0.2 footcandles or less, but in no instance greater than 0.5 footcandles when abutting a residential zoning district; and 0.5 footcandles or less, but in no instance greater than 1.0 footcandles when abutting all other districts or streets.
(2) All light fixtures located within fifty (50) feet of any residential use or residential property boundary (excluding multifamily residential uses or properties zoned for multifamily use) shall not exceed fifteen (15) feet in height and shall be mounted in such a manner that the cone of light is contained on-site and does not cross any property line of the site.
(f) Parking Lots:
(1) All luminaires shall be cut-off luminaires as defined by the latest edition of the Illumination Engineering Society of North America (IESNA Handbook).
(2) If the design is of a period or architectural style within the overall design of the project, as determined by the Architectural Board of Review, alternatives or supplements to the lighting may be used, provided that:
A. If the alternatives or supplements to the lighting is not "cut-off' luminaires as defined by IESNA, the maximum initial lumens generated by each fixture shall not exceed two thousand (2,000).
B. Mounting heights of such alternative luminaires shall not exceed fifteen (15) feet above grade.
C. All luminaires of a period or architectural style shall be approved by the Architectural Board of Review Board.
(g) Walkways, Bikeways, and Parks:
(1) Walkways and bikeways shall be illuminated to enhance security in their use.
(2) Lighting fixtures shall be designed to direct light downward, and light sources shall have an initial output of no more than one thousand (1,000) lumens.
(h) Garbage dumpsters and recycling bins must have a dedicated light source that are illuminated at levels for walkways.
(i) Landscape Lighting: Trees and shrubs shall not interfere with the distribution of pathway and transitional lighting.
