No outdoor lighting shall, after the effective date of the ordinance codified in this chapter, be installed in the R-1 or R-M zones, except in accordance with the provisions of this chapter. (Ord. 740 § 1, 2019; Ord. 700 § 2 (Exh. 1), 2012; Ord. 304 § 1, 1974)
18.28.020 Definitions.
A. Fifteen Thousand Lumens Defined. The term “fifteen thousand lumens” or the term “an aggregate fifteen thousand lumens” shall be construed to mean fifteen thousand lumens on lots fifteen thousand square feet or smaller. On lots larger than fifteen thousand square feet it shall be deemed to mean fifteen thousand lumens plus an additional one thousand five hundred lumens for each one thousand five hundred square feet or major fraction thereof by which the lot exceeds fifteen thousand square feet, up to a maximum of thirty thousand lumens.
B. “Light source” means, in generic terms, a source of optical radiation (i.e., “light”), often called a “bulb” or “tube.” Examples include incandescent, fluorescent, high-intensity discharge (HID) lamps, and low-pressure sodium (LPS) lamps, as well as compact fluorescent lamps (CFL), light-emitting diode (LED) modules, and arrays.
C. “Lumen” means the unit of measure used to quantify the amount of visible light produced by a lamp or emitted from a luminaire (as distinct from “watt,” a measure of power consumption).
D. “Outdoor lighting” means outdoor electrically powered illuminating devices, lamps and similar devices, including solar powered lights, and all parts used to distribute the light and/or protect the lamp, permanently installed or portable. (Ord. 740 § 1, 2019; Ord. 700 § 2 (Exh. 1), 2012; Ord. 304 § 1, 1974)
18.28.030 Direct rays limited to property of origin.
No light shall, after the effective date of the ordinance codified in this chapter, be installed in any R-1 or R-M zone where the direct rays from the light extend beyond the property line of the property upon which such light is installed. Individual nonreflector light bulbs not exceeding illumination equivalent to two thousand two hundred fifty lumens shall be permitted without restriction, except that the aggregate of all outdoor lights shall not exceed fifteen thousand lumens for any lot. (Ord. 740 § 1, 2019; Ord. 700 § 2 (Exh. 1), 2012; Ord. 304 § 1, 1974)
18.28.040 Direct illumination of other properties – Prohibited hours.
No outdoor lighting in the R-1 or R-M zones shall be used after seven-thirty p.m. of any day or before seven a.m. of any day where such light source results in direct illumination of a parcel of property or properties other than those upon which such light fixture or source is physically located, except that individual nonreflector light bulbs not exceeding two thousand two hundred fifty lumens shall be permitted. (Ord. 740 § 1, 2019; Ord. 700 § 2 (Exh. 1), 2012; Ord. 304 § 1, 1974)
18.28.050 Prohibited hours generally.
No outdoor lighting in the R-1 or R-M zones shall be used after nine p.m. of any day or before seven a.m. of any day, except that individual light bulbs not exceeding two thousand two hundred fifty lumens or an aggregate of fifteen thousand lumens for each lot shall be permitted. If any reflector bulbs are used the direct rays of such bulbs may not extend beyond the property line of the property upon which such light is installed. (Ord. 740 § 1, 2019; Ord. 700 § 2 (Exh. 1), 2012; Ord. 304 § 1, 1974)
18.28.060 Lighting permit – Effect.
Notwithstanding the requirements of this chapter, lights may be installed and used in a manner and at times not permitted by this chapter only upon receipt of a lighting permit issued pursuant to the provisions of this chapter. A lighting permit shall be issued if the planning commission finds that the installation or use, as conditioned, of the requested lights will not adversely affect any person’s use or enjoyment of any other property. A lighting permit shall be denied if the planning commission or the city council finds that such installation or use of lights will adversely affect any person’s use or enjoyment of any other property. (Ord. 740 § 1, 2019; Ord. 700 § 2 (Exh. 1), 2012; Ord. 529 § 23, 1991; Ord. 304 § 1, 1974)
