[HISTORY: Adopted by the Town Board of the Town of Webster 4-5-2018 by L.L. No. 2-2018 (Ch. 153 of the 1991 Code). Amendments noted where applicable.]
The following lighting design standards and guidelines are provided to ensure coordinated, safe, and nonintrusive functional lighting systems in each neighborhood. The site lighting requirements include:
A. 
Standards.
(1) 
No use shall produce a strong light or reflection of a strong, dazzling light or glare that extends beyond the lot line.
(2) 
Security lighting fixtures shall not project above the facade or roofline of any building and are to be shielded. Lighting shields shall be painted to match the surface to which they are attached. Security lighting fixtures shall be restricted to lighting only the property owner's yard or other similar areas requiring security lighting.
(3) 
Outside lighting shall be contained within yard boundary. No light spillover shall occur outside the yard area.
B. 
Guidelines.
(1) 
Soft lighting of building facades is encouraged. Building lighting should be indirect in character. Indirect wall lighting or "wall-washing" overhead down lighting or interior illumination that spills outside the protected area is discouraged.
(2) 
When possible, overhead wiring should be avoided.
A. 
Light spill. No exterior spotlighting or other high-intensity lighting on a property shall spill onto an adjacent property.
B. 
Shielding light sources. The source of any outdoor light shall be shielded so that it is not visible when viewed off the site. Exempt from this requirement are lights which are located near an entrance to a nonresidential building and low-voltage lights (as defined in the National Electrical Code) not more than 18 inches above grade also delineate a walkway or access to a building.
C. 
In cases where property owners use exterior illumination, said illumination shall be localized and unobtrusive and shall not create a nuisance to neighboring property owners. Any existing exterior illumination which is in violation of this section shall be immediately brought into compliance through the use of approved shielding, decrease in wattage or relocation. Failure to do so, upon notice of violation, shall subject the violator to the penalties set forth in § 350-106 of this Code.
D. 
Exterior lighting within any residential district shall be no more than 20 feet in height, and in no case, even by variance, shall lighting be permitted in excess of 30 feet in height.
A. 
A property owner, occupant or resident is prohibited from allowing exterior lighting to directly shine onto any neighboring property so as to become a nuisance or to disrupt the peace and/or repose of the neighborhood.
B. 
The light spillage on an adjacent property shall be less than 0.5 footcandle.
C. 
The maximum height of a pole-mounted light fixture or a building-mounted light fixture shall be 20 feet, but in no case, even by variance, shall lighting be permitted in excess of 30 feet in height.
D. 
All exterior residential lighting, whether in operation prior to or after the adoption of this chapter, shall comply with these provisions.
As used in this chapter, the following terms shall have the meanings indicated:
DIRECT LIGHT
Light emitted by a fixture from the lamp, from a reflector, or through a refractor.
FACADE LIGHTING
Permanent outdoor fixtures that are specifically intended to illuminate the exterior surfaces of buildings or structures.
FIXTURE
A complete lighting unit, including a lamp together with the parts designed to distribute the light, to position and protect the lamp and to connect the lamp to the power supply.
FIXTURE LUMENS
Total lumens emitted by a fixture.
FOOTCANDLE (abbreviated fc, lm/ft2, or sometimes ft-c)
A. 
A non-SI (SI= International System of Units) unit of illuminance or light intensity. The name "footcandle" conveys the "illuminance cast on a surface by a one-candela source one foot away." This unit is commonly used in lighting layouts in parts of the world where SAE units are used.
B. 
The unit "footcandle" is defined as the amount of illumination the inside surface of a one-foot-radius sphere would be receiving if there were a uniform point source of one candela in the exact center of the sphere. Alternatively, it can be defined as the illuminance on a one-square foot surface of which there is a uniformly distributed flux of one lumen.
FULLY SHIELDED FIXTURE
A fixture that allows no direct light from the fixture above a horizontal plane through the fixture's lowest light-emitting part, in its mounted position.
GLARE
Light emitted by a fixture that causes discomfort or reduced visibility.
ILLUMINANCE
The luminous power incident per unit area of a surface.
LAMP
A light bulb or other component of a fixture that changes electricity into visible light.
LIGHT TRESPASS
Light that falls beyond the property it is intended to illuminate.
LUMEN
A standard unit of measurement of the quantity of light emitted from a lamp.
ORNAMENTAL ROADWAY LIGHTING
A roadway lighting fixture that serves a decorative function in addition to a roadway lighting function, having an historical period appearance or decorative appearance.
PARKING LOT LIGHTING
Permanent outdoor fixtures specifically intended to illuminate uncovered vehicle parking areas.
PERMANENT OUTDOOR FIXTURE
A fixture for use in an exterior environment installed with mounting not intended for relocation.
ROADWAY LIGHTING
Permanent outdoor fixtures specifically intended to illuminate public roadways.
SKY GLOW
A condition caused by light directed upwards or sideways, reducing one's ability to view the night sky.
STATE AGENCY
Any state department, office, board, commission, agency or a public authority or public benefit corporation, at least one of whose members is appointed by the governor.
No property owner or lessee shall install or cause to be installed any new or replacement permanent outdoor fixture unless the following conditions are met:
A. 
In the case of roadway lighting or driveway lighting; whether mounted to poles, buildings or other structures, the fixture is fully shielded.
B. 
In the case of building-mounted fixtures not specifically intended for roadway lighting, driveway lighting, or facade lighting, the fixture is fully shielded when its initial fixture lumens is greater than 3,000 lumens.
C. 
In the case of facade lighting, the fixture is shielded to reduce glare, sky glow, and light trespass to the greatest extent possible.
If a court determines that any clause, sentence, paragraph, subdivision, or part of this chapter or the application thereof to any person, firm or corporation, or circumstance is invalid or unconstitutional, the court's order or judgment shall not affect, impair, or invalidate the remainder of this chapter but shall be confined in its operation to the clause, sentence, paragraph, subdivision, or part of this chapter or in its application to the person, individual, firm or corporation or circumstance directly involved in the controversy in which such judgment or order shall be rendered.
This chapter shall take effect immediately upon filing with the Secretary of State.
