(A) Lighting. Shall at a minimum meet all applicable local, state, and federal codes and regulations.
(B) Exterior lighting plan. An exterior lighting plan, including a photometric plan (which covers the parcel which is the site of the building or project in question), appropriate pole, fixture, and lamp cut sheets, and descriptions of lenses and appropriate data tables, shall be submitted for site plan review.
(1) The exterior lighting plan shall be prepared by a licensed professional engineer, who shall certify that the exterior lighting plan complies with this section.
(2) The photometric plan shall be prepared in a scale that is easily legible. The current edition of the IES Lighting Handbook, published by the Illumination Engineers Society is the standard to be used by the engineer as a guide for the design and testing of lighting plans.
(3) The standards contained therein shall apply unless standards developed and adopted by this section or subsequent amendments are more restrictive, in which case the more restrictive standards shall apply.
(4) Lighting equipment must be of commercial quality and listed with a Nationally Recognized Testing Laboratory (NRTL) such as Underwriters Laboratories (U.L.) or Electrical Testing Labs (ETL).
(C) Pole lighting height standard. All private, pole mounted, outdoor surface lot lighting shall be limited to 30 feet in height above grade. Non-vehicular pedestrian areas shall incorporate pedestrian scale lighting where appropriate.
(D) Illumination levels. The maximum illumination for a project shall be 12 f.c. with the minimum average illumination, at grade, to be not less than two f.c., average maintained over the site. The illumination level at the property line of any project shall be a maximum of 0.5 f.c. To avoid glare or spill light from encroaching onto adjacent properties, illumination shall be installed with house side shields and reflectors, and shall be maintained in such a manner as to confine light rays to the premises of the building or project. Color correlated temperature (CCT): The maximum CCT for a site shall be as follows:
Location | Maximum Color Correlated Temperature |
B-2, B-3, C-1, I-L, I-M and I-H Zoning Districts | 4,000 K |
B-1, PO, A, U, A-E, R-R, REC and CF Zoning Districts | 3,000 K |
Residential Common Area | 3,000 K |
Natural Areas, Preserves and Environmentally Sensitive Areas | 3,000 K |
(E) Installation. The lighting installation shall not be placed in permanent use until a letter of compliance from a registered engineer or architect has been provided stating that installation has been field checked and meets the requirements of this section.
(F) Architectural and landscape lighting.
(1) Lighting should be designed, installed, and controlled to ensure that the lights only illuminate the intended object(s).
(2) The placement of light poles shall consider existing and proposed ultimate growth of all landscaping and tree canopies to minimize or prevent conflicts between landscaping and lighting systems.
(3) To the extent practical and where possible, lighting fixtures shall be directed downward rather than upward. Directional shielding shall be implemented to minimize or prevent glare, light trespass, and light pollution.
(4) When up lighting is required, lighting systems should be low in intensity and incorporate full shielding.
(5) Ground mounted lighting should be screened from view.
(G) Construction lighting.
(1) All construction site lighting fixtures must be full cut-off or directionally shielded fixtures that are aimed and controlled so the directed light is substantially confined to the object intended to be illuminated and not directly visible outside of the property.
(2) Interior construction lights shall be extinguished after the work has been completed for the day unless needed to ensure safety, security, or legal compliance.
(3) A building is no longer considered under construction once exterior walls and windows are installed and permanent lighting replaces temporary lighting as the primary source of light for the building.
(H) Nonconforming lighting.
(1) When 50% or more of any component (e.g., luminaires, poles) of the exterior lighting system at a building or project is upgraded, changed, or replaced (not including regular maintenance), such component for the remainder of the exterior lighting shall be brought in compliance with all applicable requirements of this section.
(2) In the event less than 50% of the exterior lighting system is being replaced and the Planning and Economic Development Director or designee determine that an equivalent replacement is no longer obtainable, due to obsolescence or lack of supply, such component for the remainder of exterior light shall be brought in compliance with all applicable requirements of this section.
