§ 15-5.0402 Exterior Lighting Plan Required.

A. General. At the time any exterior light is installed or substantially modified, and whenever a Zoning Compliance Permit application is made, an exterior lighting plan shall be submitted to the City in order to determine whether the requirements of this Section have been met and that adjoining property will not be adversely impacted by the proposed lighting.

B. Lighting Plan Elements. A Lighting Plan submitted pursuant to this Ordinance shall have, at a minimum, the following elements:

1. A catalog page, cut sheet, or photograph of the luminaire including the mounting method.

2. A photometric data test report of the proposed luminaire graphically showing the lighting distribution at all angles vertically and horizontally around the luminaire.

3. A plot plan, drawn to a recognized engineering or architectural scale, indicating the location of the luminaire(s) proposed, mounting and/or installation height in feet, the overall illumination levels (in footcandles) and uniformities on the site, and the illumination levels (in footcandles) at the property boundary lines. This may be accomplished by means of an isolux curve or computer printout projecting the illumination levels.

4. A graphic depiction of the luminaire lamp (or bulb) concealment and light cut-off angles.

§ 15-5.0403 Exterior Lighting for Specified Outdoor Recreational Uses.

Ball diamonds, playing fields, golf driving ranges, tennis courts and similar outdoor recreational facilities have unique requirements for nighttime visibility and generally have limited hours of operation. These uses may be exempted from the exterior lighting standards of the Division if the applicant can satisfy the Plan Commission, upon Site Plan Review, that the following requirements are met:

A. Site Plan. The Site Plan must meet all other requirements of this Division and Ordinance; and

B. Exterior Light Sources. Any exterior light sources shall not exceed the maximum permitted post height of 60 feet; and

C. Shielded Luminaires. If the luminaire is shielded in either its orientation or by a landscaped bufferyard to prevent light and glare spill-over to adjacent residential property(s) or residential zoning districts, then the luminaire may exceed a total cut-off angle of 90°. The maximum permitted illumination at the interior bufferyard line of all required bufferyards shall not exceed two footcandles; and

D. Lighting Plan Required. A Lighting Plan meeting the requirements of § 15-5.0402 of this Division shall be submitted to the Plan Commission for review and approval.

§ 15-5.0404 Street Lighting.

Street lighting shall conform to the standards set forth by the State of Wisconsin for State Trunk Highways, Milwaukee County for County Trunk Highways, and the City for City streets and highways.

§ 15-5.0405 Searchlights.

The Zoning Administrator may permit the temporary use of a searchlight for advertising purposes in any non-residential zoning district, provided that the searchlight will not be located in any public right-of-way, will not be located closer than 10 feet to an adjacent property, and will not cause a hazard to traffic or adjoining properties. Searchlight permits shall not be granted for a period or more than five days in any six-month period.

§ 15-5.0406 Additional Regulations.

Notwithstanding any other provision of this Section to the contrary the following provisions shall also be applicable.

A. Flickering and Flashing Lights. No flickering or flashing lights shall be permitted.

B. Light Sources and/or Luminaires Not to be Located Within Required Bufferyards. Light sources or luminaires shall not be located within required bufferyard areas except on pedestrian walkways.

C. Requirements of Other Applicable Codes and Ordinances to be Met. The provisions of this Division are designed to supplement other applicable ordinances and codes and not as a substitute. All outdoor electrically powered illuminating devices shall be installed in conformance with the provisions of this Ordinance, applicable building codes and ordinances, electrical codes and ordinances, and all other codes and ordinances as applicable and under appropriate permit and inspection.

§ 15-5.0407 Light Measurement.

A. Metering Equipment. Lighting levels shall be measured in footcandles with a direct-reading, portable light meter. The meter shall be read within an accuracy of plus or minus 5%. It shall have been tested, calibrated, and certified by an independent commercial photometric laboratory or the manufacturer within 30 days of its use.

B. Method of Measurement. The meter sensor shall be mounted not more than six inches above ground level in a horizontal position at the interior line of the bufferyard or at the property line, as required herein. Readings shall be taken only after the cell has been exposed long enough to provide a constant reading. In order to eliminate the effects of moonlight and other ambient light, measurements shall be made after dark with the light source in question on, then with the same sources off. The average of the two readings shall be compared to the maximum permitted illumination allowed under this Division.
