The purpose of this section is to provide minimum standards for effective, economical, and attractive outdoor lighting.

(Ord. No. 2008-3179, § 1, 12-18-08)

It is the intent of this section to:

A.

Discourage excessive lighting.

B.

Minimize glare and light trespass.

C.

Protect neighbors from the consequences of stray light.

D.

Create a safe environment in hours of darkness.

E.

Regulate the type of light fixtures, lamps, and standards.

(Ord. No. 2008-3179, § 1, 12-18-08)

A.

This section shall apply to the installation of new outdoor lighting fixtures or the replacement of existing outdoor fixtures. Replacement of a fixture shall mean a change of fixture type or change to the mounting height or location of the fixture. Routine lighting maintenance, such as changing lamps or light bulbs, ballast, starter, photo control, housing, lenses, and other similar components, shall not constitute replacement and shall be permitted, provided such changes do not result in a higher lumen output.

B.

Exceptions. This section shall not apply to:

1.

Street lighting, which is regulated by the subdivision code.

2.

Light fixtures and standards required by the Federal Communications Commission or Federal Aviation Administration.

3.

Temporary lighting fixtures for the purpose of performing nighttime road construction work on major thoroughfares.

4.

Holiday lighting fixtures and displays.

5.

Motion activated lights on lots developed with single-family dwellings provided that:

a.

Fixtures emit initial lighting levels of six thousand (6,000) lumens or less;

b.

Are extinguished within five (5) minutes upon cessation of motion; and

c.

Are aimed such that the lamp or light bulb portion of the fixture is not visible at five (5) feet above the property boundary.

6.

Outdoor lighting fixtures with initial light outputs of two thousand (2,000) lumens or less on lots developed with single-family dwellings.

(Ord. No. 2008-3179, § 1, 12-18-08)

The applicant for any site plan which proposes new or replacement outdoor lighting shall submit a lighting plan that complies with this section for review and approval by the city planner. The following information shall be included in the plan:

A.

A diagram indicating the location of all standards and fixtures and the proposed type of illuminating devices, fixtures, lamps, supports, reflectors, and other devices as well as a photometric plan denoting foot candle levels;

B.

A description of the illuminating devices, fixtures, lamps, color of lights, supports, reflectors, and other devices.

C.

A cut sheet delineating all light standards and fixtures.

(Ord. No. 2008-3179, § 1, 12-18-08)

A.

All outdoor light fixtures and lamp types installed and hereafter maintained shall use only shielded and/or enclosed light fixtures as specified in table 18.1, shielding and enclosure requirements.

B.

Building mounted lighting, including both utilitarian and decorative applications, shall be limited to fully shielded, cut-off optics, flat lens luminaires.

C.

Exterior building lighting shall be architecturally integrated with the building style, material, and color. The color of exterior lamps shall be consistent with that on surrounding buildings.

D.

Exterior building lighting that utilizes exposed neon tubing or similar outline lighting device is prohibited.

E.

The fixture lamp types within table 18.1, shielding and enclosure requirements, are further limited as follows:

1.

Clear mercury lamps are not permitted for general illumination. Only mercury vapor lamps that are environmentally safe, as defined (by the manufacturer) by their ability to be recycled and self-extinguish, are permitted.

2.

Except where color rendition is critical, this lamp type is a permitted light source to minimize undesirable emission into the night sky due to its monochromatic spectral distribution.

3.

Metal halide lamps shall be installed only in enclosed luminaires.

4.

Warm white and natural lamps are required in order to minimize detrimental effects.

5.

For the purposes of this subsection, quartz lamps are not considered an incandescent light source.

(Ord. No. 2008-3179, § 1, 12-18-08)

To achieve uniformity of light distribution and reduce light pollution, glare, and spill-over, all outdoor lighting for non-security purposes shall meet the foot candle standards set forth in table 18.2, footcandle standards.

(Ord. No. 2008-3179, § 1, 12-18-08)

A.

Exterior lighting shall be provided in all parking areas in accordance with this subsection.

B.

Parking area lighting shall provide the minimum lighting necessary to ensure adequate vision and comfort in parking areas, and to not cause glare or direct illumination onto adjacent properties or streets or public/private rights-of-way.

C.

Parking area lighting shall be designed and installed so as to achieve the illumination levels set forth in table 18.3, illumination standards in footcandles for parking areas. Lighting shall be maintained so as to achieve not less than eighty (80) percent of the minimum and average illumination levels.

D.

For the purpose of table 18.3, "commercial" refers to parking areas for any land use, regardless of zoning designation, in which goods or services are offered to the general public on the premises.

E.

The city planner may permit lighting arrangements exceeding the maximum initial level set forth in table 18.3 to allow lighting designs which substantially exceed the required minimum and average illumination levels.

F.

Parking lot lighting shall be fully shielded flat-lens enclosed luminaires.

G.

Mounting heights of lighting fixtures shall not exceed thirty (30) feet.

(Ord. No. 2008-3179, § 1, 12-18-08)

A.

Areas under canopies and around pump islands shall be illuminated so that the minimum horizontal illuminance at grade level is no more than five and one-half (5.5) footcandles. The ratio of average to minimum illuminance shall be no greater than four to one (4:1). This yields an average illumination level of no more than twenty-two (22) footcandles.

B.

Areas on the apron away from the gasoline pump islands used for parking or vehicle storage shall be illuminated in accordance with the requirements for parking areas. If no gasoline pumps are provided, the entire apron shall be treated as a parking area.

C.

Light fixtures mounted on canopies shall be recessed so that the lens cover is recessed or flush with the bottom surface of the canopy and/or shielded by the fixture or the edge of the canopy so that light is restrained to no more than eighty-five (85) degrees beyond the vertical plane.

(Ord. No. 2008-3179, § 1, 12-18-08)

Lighting fixtures within outdoor plazas and similar public gathering places shall be either low-level fixtures (fifteen [15] foot maximum) and/or a combination of bollards and uplighting in order to create a "human scale" environment.

(Ord. No. 2008-3179, § 1, 12-18-08)

A.

The lighting of outdoor recreation and athletic fields shall be as per the standards contained in the Illuminating Engineering Society of North America's "RP-6-01 Recommended Practice for Sports and Recreational Area Lighting," a copy of which is available in the department of community development. The following provisions shall also apply:

1.

Illumination and design standards for recreational uses not specifically included in the publication shall be determined by the city planner.

2.

Illumination and design standards may be further limited by a conditional use permit ordinance or modified by a planned district ordinance.

3.

Spill light shall not exceed 1.1 initial or 0.8 maintained footcandles, as measured vertically five (5) feet above grade, along any adjoining property line of an "R", "NU", or "RD-MXD" zoning district.

4.

Other components of recreational or sports facilities such as parking lots, restrooms, ticket sales, concession stands, bleachers, or other spectator viewing areas shall be subject to the other provisions of this section which pertain to each.

(Ord. No. 2008-3179, § 1, 12-18-08)

All required lighting installations must be regularly maintained (cleaned, repaired, etc.), such that they always provide acceptable luminance levels and glare control.

(Ord. No. 2008-3179, § 1, 12-18-08)

The compliance with standards and regulations contained in this section shall be in accordance with those established in article 10 of this chapter.
