(A) Automatic switching requirements. All lighting shall have an automatic control or device that will extinguish outdoor lighting when sufficient daylight is available. This can be done through a photoelectric switch, astronomic time switch or equivalent functions from a programmable lighting controller, building automation system or lighting energy management system, all with battery or similar backup power or device.
(B) Architectural/landscape lighting. Architectural lighting used to illuminate the wall of a building or landscape lighting used to illuminate trees or other landscape elements is permitted subject to the following:
(1) Architectural and landscape lighting that is directed downward onto a wall, tree or other landscape feature shall be included in the total lumen limits per site standards.
(2) In residential lighting zones, architectural and landscape lighting that is directed upward onto a wall, tree or other landscape feature shall be partially shielded and shall be included for the purpose of measuring total lumens for partially shielded fixtures.
(C) Flagpole lighting. Nothing herein shall be construed to limit or apply to any flagpole lighting in existence prior to the adoption of this chapter. For flagpole lighting installed after the adoption of this chapter, the following shall apply:
(1) Flagpoles illuminated from below are limited to a height of 25 feet aboveground level. Only a single spot-type fixture whose maximum initial output is 75 lumens per foot, measured from the light fixture to the top of the flagpole is permitted. The fixture shall be mounted so that the lens is perpendicular to the flagpole.
(2) Flagpoles illuminated from above may utilize a light fixture attached to the top of the flagpole or a fixture mounted above the top of the flagpole on a structure within 15 feet of the flagpole, each of which must direct light to the ground and shall not exceed 800 lumens.
(3) Lighting used for flagpole illumination shall be included in the total outdoor light output calculation for non-residential lighting zones.
