(A) Generally. Outdoor lighting installed after the effective date of this Zoning Ordinance shall not exceed the footcandle (fc) values in Table 156.H.002-1, Illumination Standards, and Table 156.H.002-2, Parking Lot Lighting.
Illumination Standards | ||||
Zoning Districts | Maximum Footcandle adjacent a Residential Property Line1 | Maximum Footcandle Adjacent to a Nonresidential Property Line1 | Maximum Footcandle Adjacent a Public Right of Way1 | Average Permitted Horizontal Footcandles1 |
All values are stated in footcandles (fc) | ||||
AG, RR, RL, RM, RH | 0.2 | 0.2 | 0.5 | 0.2 |
MU, UC, GC, PI, REC | 0.5 | 2.0 | 1.0 | 5.0 |
GI | 0.5 | 1.0 | 1.0 | 2.0 |
Table Notes: 1. Horizontal footcandles are measured horizontal from the surface of the property by holding a light meter parallel to the ground approximately one foot off the surface. | ||||
(B) Nuisance prohibited. Outdoor lighting shall be deflected, shaded, and focused away from abutting properties and shall not be a nuisance to such abutting properties.
(C) Parking lot lighting. Parking facilities, including structured and open parking lots, spaces, drive aisles, entrances, and stairways must meet the illumination standards set out in Table 156.H.002-2, Parking Lot Lighting. Light fixtures must be designed and installed to prevent glare from being cast outside of any parking structure or parking lot, and shall not exceed the limits stated in Table 156.H.002-1, Illumination Standards.
Parking Lot Lighting | |
Standard | Footcandle Requirement1 |
Minimum Horizontal Illuminance1 | 0.2 fc |
Average Horizontal Illuminance1 | 2.0 fc |
Uniformity Ratios (Horizontal Illumination) Average to Minimum | 4:1 |
Maximum to Minimum Ratio | 20:1 |
Table Notes: 1. Measured on the parking surface, without any shadowing effect from parked cars or trees. | |
(C) Canopy lighting. Canopy lighting for uses that have sheltered outside work or service areas, such as vehicle gas and fueling stations, must recess all luminaries into the canopy so that they cannot be viewed off-site from an eye height of four feet (to protect automobile drivers from glare).
(D) Wall pack lighting. Any project that proposes the use of wall pack lighting on the perimeter of the property shall be required to prepare an exterior lighting plan for review and approval by the Zoning Administrator.
(E) Outdoor recreation facilities.
(1) Average permitted horizontal footcandle exemption. Illumination levels for sports facilities may exceed the maximum permitted horizontal footcandle requirements and shall be:
(a) Designed to be no higher than recommended for the appropriate class of play, as defined by the current version of the Illuminating Engineering Society of North America (IESNA) publication IES RP-6-15; and
(b) Comply with the maximum footcandles adjacent to residential and nonresidential property lines standards established in Table 156.H.002-1, Illumination Standards.
(2) Shielding. Fixtures used for non-aerial sports shall be fully-shielded. Fixtures used for aerial sports, such as baseball and softball shall be shielded to the full extent possible while also allowing the minimum of vertical illuminance needed to track the ball.
(3) Certification. Lighting systems for outdoor recreational facilities shall be designed and certified by an engineer registered in the state as conforming to all applicable restrictions of this Zoning Ordinance before construction commences.
(F) Prohibitions. The following are prohibited:
(1) Vehicular safety. Any fixed light not designed for roadway illumination that produces incident or reflected light that could impair the operator of a motor vehicle;
(2) Searchlights. The installation, use, or maintenance of beacons or searchlights;
(3) Building facade lights. Lights that are mounted on the ground or poles for the purpose of illuminating a building facade; and
(4) Building outline lighting. Exposed strip lighting or neon tubing used to illuminate building facades or outline buildings or windows or flickering or flashing lights installed in like fashion, except for temporary decorative lighting.
