§ 151.031  OUTDOOR LIGHTING.
   (A)   Applicability.  All outdoor electrically powered illuminating devices shall be installed in conformance with the provisions of this section, the Building Code and the Electrical Code of the Town of Lakeside as applicable and under appropriate permit and inspection. These lighting standards shall apply to all non-residential uses in the Town of Lakeside. Unless otherwise stated, this chapter does not regulate lighting in public road rights-of way.
   (B)   Outdoor lighting plan.  An outdoor lighting plan must be submitted separately from any required site plan or landscape plan on all public or private properties, including rights-of-ways, public easements, franchises and utility easements for approval by the building official. An outdoor lighting plan shall be submitted prior to issuing a building permit. Plans shall include the following:
      (1)   A layout of the proposed fixture locations;
      (2)   The light source;
      (3)   The luminous area for each proposed light source with proposed foot candle measurements;
      (4)   The type and height of the light fixture or of the light source above grade.
      (5)   The type of illumination.
   (C)   General lighting requirements.
      (1)   Unless otherwise provided herein, illumination, where required by this chapter, shall have intensities and uniformity ratios in accordance with the current recommended practices of the Illuminating Engineering Society of North America (IESNA) as from time to time amended.
      (2)   Unless otherwise provided herein, all building lighting for security or aesthetics will be fully-shielded type, not allowing any upward distribution of light. Wallpack type fixtures are acceptable only if they are fully-shielded with 80° cut-off.
      (3)   No use or operation in any district shall be located or conducted so as to produce glare, or either direct or indirect illumination across the bounding property line from a source of illumination into a residentially zoned property, nor shall any such light be of such intensity as to create a nuisance or detract from the use and enjoyment of adjacent property. For the purposes of this section, a NUISANCE shall be defined as more than one-tenth (0.25) of one foot-candle of light measured at the residential property line and twenty-five hundredths (2.25) of one foot-candle at any adjoining non-residential property line.
      (4)   Shielding shall be required in all outdoor lighting installations as specified below.

   (D)   Illumination.
      (1)   Measurement. Illumination levels of outdoor lighting shall be measured by a qualified professional according to generally accepted IESNA methods.
      (2)   Computation of illumination. Illumination at a point may be computed in lieu of measurement. Computation methods shall consist of a generally accepted IESNA method, using certified photometric data furnished by the fixture manufacturer, lamp manufacturer, photometric laboratory, or other reliable authority satisfactory to the town. Computations shall be based on new, properly seasoned lamps, diffusers and other appurtenances in place, and with proper regard taken for mounting height, relative elevation, natural and manmade objects.
      (3)   Limitations on neighboring property. The limit of illumination on neighboring property from one  establishment shall be by zoning of the neighboring property. Maximum computed or measured foot-candles at the neighboring property line shall not exceed:
   (E)   Non-residential lighting parameters. 
      (1)   All non-essential lighting shall be turned off after business hours, leaving only necessary lighting for non-residential districts site security.
      (2)   Floodlights, accent, aesthetic and security lights must be fully shielded and no up-lighting shall be permitted except that lighting of 75 watts or less are excepted if necessary for security purposes.
      (3)   Parking lots and vehicle movement areas shall not exceed a maximum illumination value of ten foot-candles nor a minimum illumination value of 1.0 foot-candles. Lamps in decorative lantern type fixtures shall not exceed a maximum of 100 watts. Total pole and fixture height shall not exceed a maximum of 32 feet, measured from grade at the base. Taller poles may be considered in some situations upon approval of a special exception by the Zoning Board of Adjustment.
      (4)   Display, building and aesthetic lighting must be externally lit from the top and shine downward. The lighting must be fully-shielded to prevent direct glare and/or light trespass. The lighting must also be substantially contained to the target area.
      (5)   Limitations on establishment property. The maximum outdoor initial computed or measured illuminance level on the establishment property shall not exceed 20 foot-candles outdoors at any point, except that lighting under canopies (such as service stations) shall not exceed 40 foot-candles.
   (F)   Public and semi-public recreational facilities. Any light source permitted by this section may be used for lighting of outdoor recreational facilities (public or private), such as, but not limited to, football fields, soccer fields, baseball fields, softball fields, tennis courts, or show areas, provided all of the following conditions are met:
      (1)   Any illumination level exceeding a maximum of twenty foot-candles must receive prior approval by the Zoning Board of Adjustment by means of a special exception.
      (2)   All fixtures used for event lighting shall be fully shielded, or be designed or provided with sharp cut-off capability, so as to minimize up-light, spill-light, and glare.
      (3)   All events shall be scheduled so as to complete all activity before or as near to 10:30 p.m. as practical, but under no circumstances shall any illumination of the playing field, court, or track be permitted after 11:00 p.m. except to conclude a scheduled event that was in progress before 11:00 p.m. and circumstances prevented concluding before 11:00 p.m.
   (G)   Prohibited lighting elements.  Unless otherwise authorized, the following shall be prohibited except upon prior approval of a special exception by the Zoning Board of Adjustments.
