A. Lighting Standards for All Lighting Zones:
1. Fully Shielded: Only fully shielded, downcast, opaque fixtures are permitted.
2. Maximum Fixture Height: Maximum fixture height as measured from finished grade:
|
Residential |
15 feet |
|
Commercial |
18 feet |
|
Pedestrian pathways |
10 feet |
|
Upper story decks |
7 feet above deck |
|
Eave overhangs (e.g., soffit) |
10 feet plus 1 foot for every 5 feet from edge of eave* |
|
Bistro lights |
15 feet above grade or 8 feet above rooftop deck |
*For example, for a 20-foot high eave with a 10-foot overhang, a fixture may be 12 feet high from grade or upper level deck (10 feet + 2 feet).
3. Lamp Type: All lamp types must be a white color, with a CCT that does not exceed three thousand kelvins (3,000 K).
a. LED: Permitted at a maximum of nine hundred fifty (950) emitted lumens per fixture.
b. Fluorescent: Must be ENERGY STAR rated with adequate cold rating, permitted at a maximum of fifteen watts (15 W) per fixture.
c. Incandescent: Permitted on building mounted or signage fixtures at a maximum of sixty watts (60 W) per fixture.
d. All Other Lamp Types: Must be ENERGY STAR rated and shall not exceed nine hundred fifty (950) emitted lumens per fixture.
4. Bistro Lighting: Temporary bistro lighting is permitted at an exterior food and beverage area designated by the site plan to provide light and ambiance in Lighting Zones 1 and 2. Bistro lighting is allowed for residential properties up to 150 square feet over a deck or patio in all zones. The term "temporary" as used in this section means from May 1 through October 31 of the same year. At all other times bistro lighting is unlawful. The following standards shall apply to temporary bistro lighting:
a. Be used only with "warm" color LED bulbs that do not exceed a temperature of two thousand eight hundred kelvins (2,800 K);
b. Be fully shielded and downcast;
c. For commercial uses all bistro lighting shall not be highly visible from the right-of-way when located on a rooftop (e.g., rooftop deck screened on a minimum of two (2) sides by wall, adjacent buildings, etc.), and must be set back a minimum of 5 feet from the rooftop edge.
B. Lighting Standards for Lighting Zone 1 (LZ-1) (High Ambient Lighting Zone):
1. Fixtures: Semi-opaque fixtures are allowed in LZ-1 provided they are fully shielded and downcast.
2. Pole Lights Generally: Pole lights may have a maximum of two (2) light fixtures per pole.
3. Photometric Plan: Commercial and mixed use properties require a photometric plan of estimated foot-candle levels with maximum and average illumination. Incident light on the ground shall not be greater than one (1) foot-candle at the property line, except at site entry points. The illumination levels on all commercial and mixed use properties shall not exceed by more than ten percent (10%) the values recommended by the Illuminating Engineering Society for the use. Cut-sheets for all exterior light fixtures shall be submitted with the photometric plan.
4. Overhead Walkway Lighting: Overhead walkway lighting is permitted year round.
5. Bistro Lighting: Temporary bistro lighting is permitted.
C. Lighting Standards for Lighting Zone 2 (LZ-2) (Medium Ambient Lighting Zone):
1. Pole Lights: Pole lights may have a maximum of two (2) light fixtures per pole.
2. Photometric Plan: Commercial and mixed use properties require a photometric plan of estimated foot-candle levels with maximum and average illumination. Incident light on the ground shall not be greater than one-half (0.5) foot-candle at the property line, except at site entry points. The illumination levels on all commercial and mixed use properties shall not exceed by more than ten percent (10%) the values recommended by the Illuminating Engineering Society for the use. Cut-sheets for all exterior light fixtures shall be submitted with the photometric plan.
3. Location: The setbacks from the property line shall be at least equal to the height of the light fixture. Parking facility lighting shall follow the setback requirements defined in section 9-3-9 of this title.
4. Overhead Walkway Lighting: Overhead walkway lighting is permitted year-round.
5. Bistro Lighting: Temporary bistro lighting is permitted.
D. Lighting Standards for Lighting Zone 3 (LZ-3) (Low Ambient Lighting Zone):
1. Pole Lights: Pole lights may have a maximum of one (1) light fixture per pole.
2. Photometric Plan: Commercial, mixed use or multifamily residential properties require a photometric plan of estimated foot-candle levels with maximum and average illumination. Incident light on the ground shall not be greater than two-tenths (0.2) foot-candle at the property line, except at site entry points. The illumination levels on all commercial and mixed use properties shall not exceed by more than ten percent (10%) the values recommended by the Illuminating Engineering Society for the use. Cut-sheets for all exterior light fixtures shall be submitted with the photometric plan.
3. Location: The setbacks from the property line shall be at least equal to the height of the light fixture. Parking facility lighting shall follow the setback requirements defined in section 9-3-9 of this title. (Ord. 5, Series 2024)
