The fixture must shield the lamp in such a way that there will be total cutoff when viewed from 100’ or more from the light source. i. Shoebox fixtures are prohibited. d. Angle: all fixtures, except any lighting specifically exempted in this Chapter, shall be directed downward. i. For the lighting of predominately horizontal surfaces, fixtures shall be installed and aimed straight downward. ii.

Lamp: any bulb type, including but not limited to LEDs, metal halide, and highpressure sodium may be used, with the requirement that the color shall be soft white or amber. Bulbs exceeding 4000k in color temperature are prohibited, except that field lighting for sports fields shall not exceed 4200k in color temperature. f. Drawings: design and location of standards and fixtures shall be specified on the site development drawings. g. Flags: the Unites States flag and the state flag shall be permitted to be illuminated from dusk till dawn. All other flags shall not be illuminated past 11:00 p.m. Flag lighting sources shall not exceed 10,000 lumens per flagpole. The light source shall have a beam spread no greater than necessary to illuminate the flag. 2. Residential Lighting: a. All residential development: i. Floodlights are prohibited, with the exception that intermittent security lighting is permitted. Such security lighting shall be directed so that light does not trespass onto adjacent property and may be activated by motion sensor or other security system. ii. Street and parking lot pole lighting fixtures and assemblies shall be metal. iii. Street and parking lot pole lighting fixtures and assemblies shall be black. iv. Street and parking lot pole lighting assemblies shall include an arm and bell shade, or a pole and lantern configuration as outlined in the Technical Standards and Specification Manual. v. Building lighting shall be full cutoff and downward directed, and only for the illumination of vertical surfaces such as building facades and signs, and shall not cast illumination beyond the surface being illuminated. b. Single Family: i. Homes located less than one half mile from Camp Williams are exempt from the general design standards except that all lighting shall be full cutoff and shall not exceed 90 watts, and no upward lighting including landscape lighting is permitted. ii. Homes located more than one half mile from Camp Williams, are exempt from the design standards except that all lighting shall be full cutoff. 3. Nonresidential Lighting: a. All wall-mounted fixtures shall not be mounted above 16’. The exception shall be those instances where there is a second story access directly from the outdoors, and under-eave lighting. Wall-mounted lighting shall be only for the illumination of vertical surfaces such as building facades and signs, and shall not cast illumination beyond the surface being illuminated. b. Intermittent lighting must be of the "motion sensor" type that stays on for a period of time not to exceed ten minutes and has a sensitivity setting that allows the lighting fixture to be activated only when motion is detected on the site. c. All trespass lighting shall not exceed one foot-candles measured at the property line. i. Exceptions: 1. Trespass lighting into residential uses shall not exceed 0.1 footcandles measured at the property line. 2. Trespass lighting along adjoining property lines of nonresidential land uses, based on existing zoning and the Future Land Use Map, shall not exceed five foot-candles measured at the property line. d. Service station canopies must utilize canopy lights that are fully recessed into the canopy or are fully shielded by the canopy. e. All freestanding lighting fixtures and assemblies shall be black. i. Regional Parks may include theme lighting fixtures in colors other than black. The color shall enhance the theme of the park and shall be approved during the site plan review process. f. Pole design shall include an arm and bell shade. i. Regional Parks may include theme lighting fixtures that do not include an arm and bell shade. The design shall enhance the theme of the park and shall be approved during the site plan review process. g. Parking lot poles shall be limited to a height of 16’ when in or within 200’ of a residential zone; all other locations shall have a height limit of 20’. h. All lighting fixtures in surface parking lots and on the top decks of parking structures shall be fitted to render them full cutoff. i. Hours: i. One hour after closing or by 11:00 p.m., whichever is earlier, businesses must turn off at least fifty percent of building lighting and lighting fixtures in surface parking lots and on top decks of parking structures; however, those lighting fixtures turned off may be set to function utilizing a motion detector system.

In no instance shall signs within one-half mile be positioned facing parallel to the adjacent boundaries of Camp W.G. Williams. b. On-premise signs may remain illuminated during regular business hours, but may not be illuminated later than one-half hour after the business is no longer open to the public, nor prior to the daily opening of the business to the public. c. External illumination for wall signs shall be positioned in a downward direction directly onto the sign in such a manner that light does not project past the sign surface being illuminated. d.
