(A) Outdoor Parking Lots, Storage and Display Areas and Driveways. Lighting for outdoor parking lots, outdoor storage and display areas, and commercial driveways shall be designed to provide the minimum lighting necessary to ensure adequate public safety, to control excessive glare onto adjacent streets and properties, and to prevent light trespass onto adjoining properties, public rights-of-way, and any public trust waters.
(1) General.
(a) All lighting fixtures used for the purpose of illuminating parking lots and driveways shall be full cut-off fixtures that meet the standards set forth in the definition as documented by the manufacturer's specification or a qualified engineer.
(b) Directional floodlighting fixtures must be full-cutoff or shielded and properly aimed so that the light source:
1. Does not produce glare;
2. Does not produce up-lighting; and
3. Contains light so that it does not trespass onto adjoining properties, public rights-of-way, and any public trust waters.
(c) The maximum mounting height for pole-mounted fixtures intended to illuminate parking lots is 30 feet measured from the base of the pole.
(2) Special Design Areas. Lighting fixtures of a particular period or architectural style such as carriage lights and post lights, may be used in special design areas. In such areas, fixtures that are not full cut-off are permitted provided that:
(a) The maximum initial lumens generated by each lamp shall not exceed 500 lumens, according to the manufacturer's specifications (the purpose of this lumen cap is to avoid cumulative use of lights that may be too bright or that may cause trespass); and
(b) Post top shall be fitted with a solid top to control up-lighting and reduce glare; and
(c) Fixture mounting height is no more than 16 feet above grade level.
(3) Standard. All illumination of parking lots, outdoor storage and display areas and commercial driveways shall comply with the intensities and uniformity ratios in Section 155.9.14 or by the standard within this section whichever is more stringent.
(B) Commercial Building Exteriors and Parking Garages. These provisions apply to all buildings and uses within the town's Commercial and Public/Semi-Public Zoning Districts and to any non-conforming nonresidential uses in other zoning districts.
(1) General. Exterior building lights may be mounted in front, at ground level, or wall mounted provided that:
(a) All light fixtures, wherever mounted, are properly aimed and full cut-off or shielded to confine the light to the area of the building being lighted and to prevent light trespass.
(b) Wall-mounted light fixtures may be mounted no higher than 20 feet above grade. The fixtures must be full cut-off or shielded and aimed to avoid up-lighting.
(c) Ground mounted fixtures must restrict up-lighting.
(d) Bare light sources (including but not limited to festive light strands, incandescent, fluorescent, high intensity discharge, and neon) used to outline property lines, open sales areas, rooflines, doors, windows, the edges of walls or any other area of the building or property visible from outside the building are prohibited, except for holiday lighting permitted from Thanksgiving through January 15th of the new year.
(e) The maximum illumination level on any vertical surface or roof of a commercial building shall not exceed 3.0 average foot-candles of vertical illuminance.
(2) Gas Station/Convenience Store Canopies.
(a) Light fixtures above 200 watts mounted on canopies shall be recessed so that the lens cover is recessed or flush with the bottom surface of the canopy and/or shielded by the fixture or the edge of the canopy so that light is restricted to no more than 85 degrees from vertical.
(b) The illumination level for canopy lighting measured at the pavement/ground level shall not exceed ten average maintained foot-candles.
(3) Parking Garages.
(a) Lighting located outside the structure shall comply with the requirements of subsection (C)(1) below. Lighting located inside the structure providing illumination that is visible from the exterior of the structure shall be full cutoff or shielded by the structure, shield, visor, hood, or louvers in a manner that contains light and glare within the structure and meets this section's standards for light trespass.
(b) The illumination level of interior lighting that is visible from the exterior of the structure shall comply with the intensities and uniformity ratios in Section 155.9.14.
(4) Standard. All illumination of commercial building exteriors, gas and convenience store canopies, and parking garages shall comply with the intensities and uniformity ratios in Section 155.9.14 or by the standard within this section whichever is the more stringent.
(C) Commercial Docks and Piers. Lighting for commercial docks and piers shall minimize glare, trespass, and restrict up-lighting.
(1) All lighting fixtures must meet the following standards:
(a) Fixtures must be full cut-off or shielded and properly aimed so that they control glare, do not produce up-lighting, and contain light to prevent trespass on adjoining uplands, public rights-of-way and public trust waters.
(b) Disabling glare that impairs the ability of boaters to safely traverse public trust waters shall be prohibited.
(c) Mounting height shall be as low as practicable but in no case shall the fixture be mounted higher than 25 feet above the lowest platform of the dock or pier.
(d) Bare light sources (including but not limited to festive light strands, incandescent, fluorescent, high intensity discharge, and neon) used to outline commercial docks and piers are prohibited.
(2) Standard. All illumination of docks and piers shall comply with the intensities and uniformity ratios in Section 155.9.14 or by the standard within this section whichever is the more stringent.
