§ 8.5. OUTDOOR SITE LIGHTING

8.5.1

Applicability

All outdoor lighting shall be subject to the following requirements.

A.

Prohibited Light Sources

The following light fixtures and sources shall not be used where the direct light emitted is visible from adjacent public areas and adjacent properties:

1.

Low-pressure sodium and mercury vapor light sources;

2.

Searchlights and other high-intensity narrow-beam fixtures, except for accent lighting as defined in 8.5.3.B

8.5.2

Design Requirements

Outdoor lighting shall primarily be used to provide safety while secondarily accenting key architectural elements and to emphasize landscape features. Light fixtures shall be designed as an integral design element that complements the design of the project. This may be accomplished through style, material or color. All lighting fixtures designed or placed so as to illuminate any portion of a site shall meet the following requirements:

A.

Fixture (Luminaire)

Light shall be directed downward and all fixtures shall be mounted horizontal to the ground surface to minimize the amount of light spillage into the night sky and onto adjacent properties. All lighting fixtures shall be cutoff fixtures in accordance with Illuminating Engineering Society (IES) standards. Tilt arms are prohibited.

B.

Fixture Height

Lighting fixtures shall be a maximum of 45 feet in height (including base) within parking areas and shall be a maximum of 15 feet in height within non-vehicular pedestrian areas.

C.

Light Source (Lamp)

Lighting with a similar color temperature shall be used for similar types of lighting on any one site throughout any development.

D.

Light Spill/Trespass

If necessary, house-side shields shall be used on light fixtures adjacent to residential zoned property to prevent glare, light spill or trespass.

8.5.3

Specific Lighting Standards

A.

Building Mounted Lighting

1.

Building mounted security light fixtures such as wall packs shall not project above the fascia or roof line of the building and shall be full cut-off

2.

Building mounted fixtures shall not be substituted for parking area or walkway lighting and shall be restricted to loading, storage, service and similar locations.

B.

Accent Lighting

Only lighting used to accent architectural features, landscaping or art may be directed upward, provided that the fixture shall be located, aimed or shielded to minimize glare and light spill into the night sky.

C.

Canopy Area Lighting

All development that incorporates a canopy area over fuel sales, automated teller machines or similar installations shall use flat lens, full cutoff fixtures and shall not exceed 25 foot-candles of illumination under the canopy.

D.

Parking Area Lighting

All non-residential parking lots shall follow Illuminating Engineering Society (IES) parking lot standards. A minimum of ½ foot-candle of illumination is required on the parking surface and a 5:1 average-to-minimum uniformity ratio over 95% of the parking surface shall be required for the parking areas.

E.

Excessive Illumination

1.

Lighting within any lot that unnecessarily illuminates and substantially interferes with the use or enjoyment of any other property shall be prohibited. Lighting unnecessarily illuminates another lot if it exceeds the requirements of this section.

2.

Any lighting used to illuminate off-street parking areas shall be down lit away from residential properties and public streets in such a way as not to create a nuisance. However, in no case shall such lighting exceed one-half (½) foot-candle measured at the lot line as measured at the time of installation.

3.

Lighting shall not be oriented so as to direct glare or excessive illumination onto streets in a manner that may distract or interfere with the vision of drivers.

8.5.4

Submission Requirements

All lighting plans must be prepared by a lighting professional and all lighting plans must contain the following:

A.

A site photometric plan indicating foot-candle levels at grade to all lot lines.

B.

The location and height of all fixtures and poles.

C.

Specifications such as average-to-minimum uniformity ratio and maximum illumination.

D.

Specifications or "cut-sheet" of each type of fixture used.
