(a) Land uses required herein to provide six (6) or more parking spaces, or one (1) or more loading spaces, shall provide lighting facilities to illuminate all parking spaces, aisles and loading spaces in accordance with the Light Level Table 1353.1 herein and the following requirements:
(1) Photometric Plan: Site plans for off street parking facilities shall be submitted to Municipality's Division of Building, Zoning and Housing for approval and shall contain a photometric plan. The photometric plan shall include all the following information:
A. Identification of all proposed light fixtures, including those used for site lighting, canopy lighting and exterior building lighting.
B. Identification of all proposed control equipment, conduit, and wiring, including material, size, and location.
C. Photometric calculations, showing a grid of individual illumination values as well as a summary of the maximum, minimum and average illumination of the pavement surface in footcandles.
D. Construction details of the pole, pole foundation, electrical trench with warning tape and pole handhole wiring.
E. Catalog cut sheets for the proposed light poles, fixtures, and any exterior control equipment.
(2) Outdoor Lighting Audit: For building additions or major renovation projects, in addition to the Photometric Plan, building owners shall submit an Outdoor Lighting Audit of existing lighting systems to the Municipality's Division of Building, Zoning and Housing for approval. The Lighting Audit shall identify each lighting type, as identified in Table 1353.1 herein, used on the site and shall include all the following information and requirements:
A. The age, condition, quality, and location of existing lighting fixtures, noting any lens discoloration, lens cracking, paint cracking, or bum marks.
B. Model and manufacturer of lighting system to obtain existing photometrics.
C. Lamp wattage and ballast type.
D. Observe the operational environment of the lighting system, noting the possibility of particulate, moisture, or dirt buildup in or around lighting fixture.
E. Observe how the lighting system is controlled and how often it is used.
F. Note the perceived color of objects within the space to characterize color quality.
G. Measure the physical layout of the existing lighting system noting luminaire height and spacing.
H. Use an illuminance meter to measure the light intensity of the existing system during dark sky conditions to determine if the existing design is appropriate for the space. Readings should be taken on the ground and at even intervals to create a "grid" of measurements. These illuminance levels can be compared to the recommended levels for the application.
I. Based upon the information gathered above, provide a report establishing conclusions about the existing lighting system including:
i. Whether the lighting system meets the original or proposed lighting needs of the space and occupants, given the required operations (energy use) and maintenance costs?
ii. Calculation of the system efficacy of each type of luminaire. How efficient is each system at delivering light to its intended surface?
iii. Calculation of the theoretical system illumination, determined from a rough lumen method or point-to-point calculation. Use lighting design software to determine if the theoretical measurements match the measured illumination values from the site. This will help determine the level of deterioration of the current lighting system, as well as if the system meets the Municipality's code requirements.
iv. Calculation of the existing lighting power density and a determination of whether it meets any applicable codes or energy standards.
v. The difference in performance characteristics between existing and lighting systems proposed for the project.
(b) Design Review and Approval: In addition to Building Construction Approval, all projects requiring Photometric Plans shall be subject to review and approved by the Municipality's Architectural Board of Review.
