ARTICLE XXXIV Design Policies
Sec. 16-711. General architectural design criteria.

(c) General lighting requirements that apply to Sections 16-712 through Sections 16-716.

(1) All exterior lights for streets, parking drives, walkways and buildings shall be metal halide (casts a white light).

(2) Light levels at the property line are to be measured as line of sight from five (5) feet above the ground at the property line to the nearest and brightest light source on the property.  Light plans shall reflect the theoretical light levels at the property line using this method.  

(3) Lighting plans must identify the light loss factors (adjustments for dirt and age of fixture/lamp) for all types of exterior lights proposed.  The specified lighting levels for any use are maximums under any fixture and are the light levels allowed without adjustments for light loss factors.  Verification measurements by the Town for lighting plan compliance can occur anytime after a fifty-hour burn-in period subsequent to an approved development’s Certificate of Occupancy.

(4) Full cut-off fixtures must be used on all exterior locations.  These fixtures are to be rated by the Illuminating Engineering Society of North America (IESNA), and lamps must be placed horizontally in the fixture.  The only exception may be building and walkway fixtures at low light levels with frosted lenses.

(5) All canopy lights must be recessed so that no lens or light source drops below the ceiling surface of the canopy.  Canopy fixtures must use horizontal lamps.

(6) In order to achieve relative light uniformity in parking lots, the light level below any light standard or pole may not be greater than ten (10) times the weakest reading between this pole and adjacent poles.

Sec. 16-715. Commercial, office, retail and industrial (CORI) developments.

(a) Site development.  These Site Development Policies define the requirements for the site development of CORI uses, including building arrangement, vehicular and pedestrian circulation, parking, open spaces, loading/servicing, etc.  (See Figure 9 at Section 16-695.)

(5) Site lighting.  The purpose of the these standards is to provide for a safe, functional, visually attractive and coordinated site lighting system.  Site lighting shall conform to the standards contained in the Lighting for Exterior Environment RP-33-99 by the Illuminating Engineering Society of North America (IESNA).  Further, the site lighting requirements are as follows:

a. Lights shall not be placed to cause glare or excessive light spillage, as defined by IESNA, on neighboring sites.

b. All parking lot and driveway lighting should provide uniform illumination in compliance with the following maximum levels of light fixture illumination (initial horizontal illuminance):

c. All light fixtures are to be concealed source fixtures except for pedestrian-oriented accent lights which are limited to a lumen rating of 1800 lumens.

d. Building-mounted lighting fixtures are not to project above the fascia or roofline of the building and are to be fully shielded (IESNA full cut-off luminaries).  The shields shall be painted to match the surface to which they are attached.  Building-mounted lighting fixtures are not to be substituted for parking lot or walkway lighting fixtures, unless they are located at or below twelve (12) feet above the area lighted.

e. Exterior wall-mounted floodlights are expressly prohibited.

f. Lighting of all pedestrian walkways, plazas, etc., is required.

g. Lighting in parking lots, walkways and plaza areas must be reduced to minimum levels adequate for security after close of operations.  Lighting of these areas need to be controlled by rheostats and timers.
