8.06 STANDARDS AND REQUIREMENTS
Amended by Ord. 2013-343 (December 11, 2013), subsection A — not yet consolidated; the text below is the earlier text. Read the ordinance.
A. Tables 1 and 2
The standards and requirements set forth in Tables 1 and 2 regulate and govern the use of, design of, construction or modification of any lighting system for the purpose of illuminating exterior areas including, but not limited to, signs, parking areas, buildings, landscaping, porches, and driveways.
Table 1 sets forth whether the proposed wattage of a luminaries is permitted, not permitted or a special use. In residential zoning districts, whether a specified wattage is permitted or not permitted is based on the width of the street right-of-way abutting the proposed luminaries. In non-residential zoning districts, the permitted wattage of proposed exterior lighting is based on whether the lighting is internal or external on the parcel, and if external (abutting a residential zoning district or street right-of-way) the setback of the proposed lighting from the property line/street right-of-way.
Uses permitted by right may be approved by the Planning and Zoning Commission pending a review of the documents submitted that meet the requirements of this Section. Uses or lighting plans that require a special use permit shall meet the requirements for special uses that provide for a public hearing held by the Planning Commission and approval by the City of Tiffin.
Table 2 sets forth the maximum allowable foot-candles to be measured both at a property line and internal to a non-residential property. The standards consider the nature of the land uses, the nature of the abutting land uses, and whether for a non-residential use the time is during hours of operation or security hours. Maximum foot-candles allowable are set for lighting internal to the property in question.
B. Total Height and Height of Luminaries (See definition for Height of Luminaries and Total Height and Figure B). The difference between total height and the height of the luminaries shall not exceed 4 feet.
C. Standards for Luminaries with Cutoffs (See Definitions and Figure C attached)
1. Cutoff Angle. To be considered a cutoff luminary, the cutoff angle must be 75 Degrees or less.
2. Height: The maximum height of cutoff luminaries, either freestanding or attached to a building or other structure, is twenty-five (25) feet as a permitted use. A luminary greater than twenty-five (25) feet shall require special use permit approval.
3. Control of Glare: A cutoff luminary shall be designed to shield the light source completely from observer three and one-half (3.5) feet above the ground at any point along an abutting property line.
D. Standards for Luminaries with No Cutoffs (See Definitions and Figure D attached)
1. Cutoff Angle: A luminary shall be considered to have no cutoff if it is unshielded or has a cutoff angle greater than 75 degrees.
2. Height The maximum permitted height of a luminary with no cutoff or with a cutoff greater than 75 degrees, that provides illumination along a property line, shall be less than the value 3 feet + (D/3), where D is the distance in feet to the nearest property line but in no case shall exceed 16 feet. The formula used herein for determining height of the luminaries does not preclude any luminaries or lighting system from meeting the foot candle performance standards set forth in Table 2.
3. Control of Glare: Any luminaries designed with no cutoff or a cutoff angle greater than 75 degrees shall be designed such that the lamp utilized is no more than 100 watts or rated for more than 10,000 lumens, whichever is less. The standards for maximum foot-candles internal and at the property line, set forth in Table 2, are still applicable. For the foot-candles - vertical measurement, the measurements shall be taken not less than three and one-half (3.5) feet above the ground line in a vertical position and vertical readings at heights greater than three and one-half (3.5) feet may be required pursuant to the direction of the Zoning Administrator. The standards for vertical foot-candles, set forth in Table 2 are applicable along the entire vertical plane along a property line.
E. Standards for Luminaries under a Canopy (for non-residential uses)
Luminaries mounted to the underside of a canopy, which provide overhead illumination, shall be recessed such that no part of the luminary or the lamp shall extend below the exterior edge of the canopy.
8.0.7 EXCEPTIONS
A. Public Roadway Lighting: Luminaries used for public roadway illumination by a public transportation agency are exempt from the requirements of this Section but may be subject to the regulations of Federal or State agencies or by other intergovernmental agreements.
B. Emergency Lighting all temporary emergency lighting needed by the Johnson County Sheriff, the Tiffin Volunteer Fire Department or other emergency services, as well as all vehicular luminaries, shall be exempt from the requirements of this Section.
C. Recreational Facilities Because of their unique requirements for nighttime visibility and their limited hours of operation, outdoor recreational facilities (public or private) such as, but not limited to, football fields, soccer fields, baseball fields, softball fields, tennis courts, golf driving ranges, show areas and other similar uses as may be determined by the office of the Planning and Zoning Commission are exempted from certain illumination and other standards as follows:
1. The uses set forth herein are specifically exempted from the maximum foot-candle requirements - internal to the site as outlined and established in Table 2. These uses are required to submit a lighting plan and shall be processed as special uses under the procedures in Section 11.07. These uses shall meet the requirements for maximum foot-candles at the property line.
2. The uses set forth herein shall be exempt from the height requirements as set forth in this Section. The Planning and Zoning Commission and City Council shall review the proposed pole heights during the special use permit review process.
D. Temporary Uses Certain temporary uses may be unable to meet the requirements of this section and the standards set forth in Tables 1 and
2. These temporary uses may be permitted subject to the approval of the Planning and Zoning Commission. The applicant for a temporary use may be required to submit the documentation required under Section 8.04 herein as a part of the application for a Temporary Use Permit.
8.08: PROHIBITED LIGHTS
A. Flickering or Flashing Lights: The City of Tiffin City Council shall permit no flickering or flashing lights unless authorized in a lighting plan approved as a special use or planned unit development.
B. Searchlight and Laser Source Lights: No searchlights, laser source lights, or any similar high intensity light shall be permitted.
C. Mercury Vapor Lamps No lamps utilizing mercury vapor shall be permitted.
8.09: NON-CONFORMING USES
A. Luminaries lawfully in place prior to the date of this Section but that do not conform to the requirements and standards of this Section shall be considered legal non-conforming uses.
B. Legal non-conforming luminaries that meet the performance standards for foot-candle levels and screening requirements of this Section but may exceed the physical standards such as height or setbacks herein may continue and are not subject to ameliorization requirements:
1. Legal non-conforming illumination systems that were not part of a specific approved lighting plan shall be brought into conformity with the criteria and standards set forth herein when the illumination system is to be replaced or modified to greater than 50 percent of its replacement value, based on the total project implementation cost. The elements for calculating the value of the illumination system are set forth below.
2. The value of the illumination system shall include the total value of the physical improvements such as luminaries, lamps, poles, wiring, and other elements and must include the value of the site area improvements where the luminaries and supporting elements are located such as parking lots, loading areas, aisles, driveways, sidewalks, landscaped areas and others. Total replacement cost shall include the design costs for the illumination system, material costs for the system elements, and the total construction cost to install the system.
3. Legal non-conforming luminaries that exceed the foot candle standards set forth in Table 2 and/or direct light or glare towards streets, parking lots, residences or property lines and result in a problematic or dangerous condition shall be either shielded, redirected or otherwise modified to meet the requirements of this Section within 60 days of notification, or apply for an extension of the time period for compliance or apply for a variation with a specific time period for amortization.
8.10: SPECIAL USES AND VARIANCES
A. Special Use Permits To receive a special use permit, a proposed lighting plan must meet the requirements of Section 8.04.
B. Variations. A lighting proposal requiring a variation shall also be required to secure a special use permit .
