An applicant may use either the “fixture height standard” or the “photometric standard,” as detailed in § 154.099. Regardless of the method chosen, outdoor lighting must be in compliance with the following standards.
(A) Safety. Either method used shall provide sufficient and safe illumination for vehicle movement and pedestrian safety.
(B) Light poles. Light poles shall not be placed in street rights-of-way or utility easements adjacent to street rights-of-way, except by franchised utility companies or by the town, as a part of a street lighting project. Light poles may be placed in other utility easements with the approval of the director; and if light poles are allowed to be placed in utility easements, a note shall be placed on the face of the site plan stating the following: “Property owner(s) assumes all liability and replacement responsibilities for any damage to light poles placed in utility easements.”
(C) Site perimeter illumination. Illumination of the perimeter of the site shall be reduced in intensity when adjacent to lesser intensive uses or public rights-of-way measured in foot-candles (fc) at three feet above grade as follows for either the fixture height or the photometric standard:
(1) Site adjoining another nonresidential zoning district: 3.0 fc;
(2) Site adjoining agricultural/residential zoning districts: 0.5 fc; and
(3) Site adjoining public rights-of-way: 3.0 fc.
(D) Shielding. Light sources shall be concealed or shielded with luminaries with cut-offs with an angle not exceeding 90 degrees to minimize the potential for glare and unnecessary diffusion on adjacent property. For purposes of this standard, “cut-off angle” is defined as the angle formed by a line drawn from the direction of light rays at the light source and a line perpendicular to the ground from the light source above from which no light is emitted.
