Section 420.100 Definitions.

[R.O. 2011 §420.100; Ord. No. 608-05 §I, 10-5-2005]
As used in this Chapter, unless the context clearly indicates otherwise, certain words and phrases used in this Chapter shall mean the following:
To spread or scatter widely or thinly.
A specific form or lamp designed to direct its output in a specific direction (a beam) but with a diffusing glass envelope. Such lamps are so designated by the manufacturers and are typically used in residential outdoor area lighting.
For lamp types that vary in their output as they age (such as high pressure sodium, fluorescent and metal halide), the optimal output, as defined by the manufacturer, is the value to be considered.
A lighting fixture constructed in such a manner that all light emitted by the fixture, either directly from the lamp or a diffusing element or indirectly by reflection or refraction from any part of the luminaire, is projected below the horizontal as determined by photometric test or certified by the manufacturer. Any structural part of the light fixture providing this shielding must be permanently affixed.
A light ray emanating directly from a lamp, reflector or lens such that it falls directly on the eye of the observer.
Seasonal type lights, limited to small individual bulbs on a string, where the output per bulb is no greater than fifteen (15) lumens.
The professional society of lighting engineers, including those from manufacturing companies and others professionally involved in lighting.
The attachment or assembly fixed in place, whether or not connected to a power source of any outdoor light fixture.
The light-producing source of electric lighting.
The complete lighting assembly, less the support assembly. For purposes of determining total light output from a fixture, lighting assembles which include multiple lamps are treated as a single unit.
Light falling where it is not needed or wanted, typically across property boundaries.
Any or all parts of a luminaire that functions to produce light.
Unit of luminous flux used to measure the amount of light emitted by lamps.
The total amount of lumens allowed for a specific use per area described.
The complete lighting unit, including the lamp, the fixture and other parts.
Any outdoor lighting used for more than one (1) purpose, such as security and decoration.
A material does not transmit light from an internal illumination source. Applied to sign backgrounds, opaque means that the area surrounding any letters or symbols on the sign either is not lighted from within or allows no light from an internal source to shine through it.
An outdoor illuminating device, outdoor lighting or reflective surface lamp or similar device, permanently installed or portable, used for illumination or advertisement. Such devices shall include, but are not limited to, lights used for:
Parking lot lighting;
Roadway lighting;
Buildings and structures;
Recreational areas;
Landscape lighting:
Billboards and other signs (advertising or other);
Product display area lighting;
Building overhangs and open canopies.
The maximum total amount of light, measured in lumens, from all outdoor light fixtures.
An area designed for active recreation, whether publicly or privately owned, including, but not limited to, baseball diamonds, soccer and football fields, golf courses, tennis courts and swimming pools.
When a light is built into a structure or portion of a structure such that the light is fully cut off and no part of the light extends or protrudes beyond the underside of a structure or portion of a structure.
A sign illuminated by light sources from the outside.
A sign illuminated by light sources enclosed entirely within the sign cabinet and not directly visible from outside the sign.
A sign, including luminous gas-filled tubes, formed into text, symbols or decorative elements and directly visible from outside the sign cabinet.
A specific form of lamp designed to direct its output in a specific direction (a beam) and with a clear or nearly clear glass envelope; such lamps are so designated by the manufacturers and typically used in residential outdoor area lighting.
Lighting which does not conform to the provisions of this Chapter and which will not be used for more than one (1) thirty (30) day period within a calendar year, with one (1) thirty (30) day extension. Temporary lighting is intended for uses, which by their nature are of limited duration, for example civic events or construction projects.
Permitting light to pass through but diffusing it so that peons, objects, etc., on the opposite side are not clearly visible.

Section 420.110 Enforcement.

[R.O. 2011 §420.110; Ord. No. 608-05 §I, 10-5-2005]
Authority Of Building Commissioner. The designated official of the City shall be responsible for the enforcement of this Chapter and may, at any time the designated official deems necessary, inspect any lighting fixture regulated by this Chapter.
Written Notice To Be Given Of Violations. If it is found that a lighting fixture is in violation of this Chapter, the designated official shall give written notice to the owner of the lighting fixture or, if the owner cannot be located within thirty (30) days by the designated official, to the owner of the premises on which the lighting fixture is located stating:
The violations found;
The conditions must be brought into compliance with this Chapter within thirty (30) days or written proof must be presented within thirty (30) days that work has been contracted to correct violations by not later than sixty (60) days from the date of the notice;
The specific standards that must be met; and
Failure to comply or to make good faith efforts to comply with the terms of this notice shall constitute grounds for the designated official to order removal of the lighting fixture at the expense of the lighting fixture owner or owner of the premises as provided by this Chapter.
Removal Of Lighting Fixtures By Designated Official. The designated official may remove a lighting fixture if:
The violations set out in a written notice have not been corrected within sixty (60) days after mailing of the notice; and/or
The lighting fixture owner or premises owner is not able to prove to the designated official's satisfaction of good faith efforts to bring the lighting fixture into compliance.
Costs To Lighting Fixture Owners Or Premises Owner. The cost of lighting fixture repair or removal shall be charged;
To the lighting fixture owner.
If the lighting fixture owner cannot be located by the designated official within thirty (30) days, to the premise owner.
Expenses Incurred To Be Assessed As Lien On Property. In the event of failure by any party to reimburse the City within sixty (60) days for costs incurred for repair or removal ordered by the designated official, the Board of Alderpersons shall certify the charges for repair or removal to the City Clerk as a special assessment represented by a special tax bill against the real property on which the lighting fixture has been installed. The tax bill shall be a lien upon the property and shall be enforced to the same extent and in the same manner as all other special tax bills. The assessment shall bear interest at the rate of ten percent (10%) per annum.

Section 420.120 Appeals and Variances.

[R.O. 2011 §420.120; Ord. No. 240-92 §16, 7-15-1992; Ord. No. 608-05 §I, 10-5-2005]
The Board of Adjustment is authorized to review or modify the designated official's order or determination with respect to lighting fixtures covered by this Chapter and to that end shall, during appeal, have all the designated official's powers. In addition, the Board may grant variances from this Chapter as provided by this Zoning Code.
Guidelines for overturning or modifying Building Commissioner's decision. The Board of Adjustment shall, in considering appeals from the designated official's order or determination, establish that the lighting fixture or application in question complies with all the requirements of this Chapter. If it is determined that the designated official's application for this Chapter to the appellant's lighting fixture or request for a permit is erroneous, then the Board of Adjustment may overturn or modify the designated official's decision.
Grounds for granting variance. The Board of Adjustment may grant variances from this Chapter where it is found that because of the limitations on character, type or total output of lighting fixtures, the permittee would be subject to undue hardship. Undue hardship, however, is not a mere loss of a possible advantage or convenience to the applicant.
Supporting regulations. Insofar as they are applicable and consistent, the provisions of Article XXII, Zoning Board of Adjustment, of Chapter 400 shall be applicable to appeals taken to the Board of Adjustment for variances from or interpretations of this Chapter.
