It is the purpose and intent of the provisions of this chapter to preserve, protect, and enhance the use and enjoyment of any and all property through the use of appropriate lighting practices and systems. Such lighting practices and systems control glare and light trespass; conserve energy and resources while maintaining nighttime safety, utility, security, and productivity; and curtail the degradation of the nighttime visual environment.

All outdoor lighting [SR] devices shall be installed in conformance with the provisions of this chapter and title 16.

(Ord. No. G30-02, § 1, 2002; Code 1976, § 19.13.110)

The provisions for outdoor lighting [SR] control are applicable to the use and development of all private and public lands, exclusive of the following:

A.

Public street lighting.

Specialized lighting necessary for safety, such as navigational or runway lighting at airports or heliports, temporary lighting associated with emergency operations, road hazard warnings and other similar operations.

D.

Outdoor recreational uses, such as ball diamonds, playing fields, and tennis courts, which have unique requirements for nighttime visibility and generally have limited hours. These uses may exceed the lighting standards provided, to the maximum extent possible, lighting is so located and directed to minimize spillover onto residential properties; and where spillover is unavoidable, a landscaped buffer yard is provided.

(Ord. No. G30-02, § 1, 2002; Code 1976, § 19.13.115)

An outdoor lighting [SR] plan shall be submitted to the department of code administration and development services before the installation or modification of any outdoor lighting [SR], except as exempted in sections 19.13.115 and 19.13.130B, to determine compliance with the requirements of this chapter. The submission of an outdoor lighting [SR] plan shall not be required to perform routine maintenance on any existing outdoor lighting [SR].

The outdoor lighting [SR] plan shall include a site plan indicating the location of light fixtures and intensity of footcandles [SR] at various points on the site, catalog cuts of the proposed fixtures, and a summary table indicating the maximum average footcandles, maximum footcandles, minimum footcandles, uniformity ratio [SR], lumen rating for each lamp type, maximum footcandles at a residential property line and/or public street right-of-way line, luminaire height [SR], and light loss factor [SR].

(Ord. No. G30-02, § 1, 2002; Code 1976, § 19.13.120)

Any luminaire [SR] with a lamp [SR] or lamps rated at a total of more than one thousand eight hundred (1,800) lumens [SR], and all spot or flood luminaires [SR] with a lamp [SR] or lamps rated at a total of more than nine hundred (900) lumens [SR], shall not emit any direct light above a horizontal plane through the lowest direct light [SR] emitting part of the luminaire [SR].

Any luminaire [SR] with a lamp [SR] or lamps rated at a total of more than one thousand eight hundred (1,800) lumens [SR], and all flood or spot luminaires [SR] with a lamp [SR] or lamps rated at more than nine hundred (900) lumens [SR], shall be mounted at a height equal to or less than twenty-five (25) feet, when the luminaire is located within fifty (50) feet of a residential property line or a public street right-of-way line.

A.

The installation and use of outdoor lighting [SR] on any land use [SR] shall be subject to the outdoor lighting [SR] standards applicable to the zoning district in which the land use [SR] is located. Except as regulated by section 19.13.125, the outdoor lighting [SR] standards for each zoning district shall be as follows:

B.

Outdoor lighting for single-family detached dwellings [SR], and multiple-family dwellings [SR] with residential parking areas [SR] shall be exempt from the outdoor lighting standards of this chapter, provided that the outdoor lamps have a power rating of less than or equal to one hundred (100) watts.

C.

The light loss factor [SR] shall be a minimum of seventy-five hundredths (0.75) and a maximum of eight tenths (0.8) footcandles [SR].

D.

The maximum light trespass [SR] permitted to spill over onto any residential zoned property or public street right-of-way from any community facility, business, or industrial zoned property shall not exceed one-half (½) horizontal footcandles.

(Ord. No. G30-02, § 1, 2002; Code 1976, § 19.13.130)

Light levels of both direct light [SR] and indirect light [SR] shall be measured in footcandles [SR] with a direct reading, portable light meter. Readings shall be taken only after the cell has been exposed long enough to provide a constant reading. Horizontal footcandle measurements shall be taken at a height of three and one-half (3½) feet above the ground.

(Ord. No. G30-02, § 1, 2002; Code 1976, § 19.13.135)

All lighting fixtures used to illuminate a sign shall be designed to focus light on the sign. Ground-mounted lighting fixtures shall be screened with plant materials, walls, berms, or any combination thereof, so that the light source is not visible.

(Ord. No. G30-02, § 1, 2002; Code 1976, § 19.13.140)

Outdoor lighting [SR] in existence prior to the effective date of this chapter and not in conformance with the requirements of this chapter shall be considered nonconforming. Nonconforming outdoor lighting [SR] shall be subject to the provisions of chapter 19.52.

(Ord. No. G30-02, § 1, 2002; Code 1976, § 19.13.145)
