§ 22.10.060. Exterior Lighting.

The standards of this Section are applicable to all outdoor night-lighting sources installed after the effective date of this Title, except for street lights located within public rights-of-way and all uses established in the Agriculture land use category. No land use permit is required for lighting facilities, though an electrical permit may be required by Title 19 of this code (the Building and Construction Ordinance).

A.

Illumination only. Outdoor lighting shall be used for the purpose of illumination only, and shall not be designed for or used as an advertising display, except as provided by Chapter 22.20 (Signs).

B.

Light directed onto lot. Light sources shall be designed and adjusted to direct light away from any road or street, and away from any dwelling outside the ownership of the applicant.

C.

Minimization of light intensity. No light or glare shall be transmitted or reflected in a concentration or intensity that is detrimental or harmful to persons, or that interferes with the use of surrounding properties or streets.

D.

Light sources to be shielded.

1.

Ground illuminating lights. Any light source used for ground area illumination except incandescent lamps of 150 watts or less and light produced directly by the combustion of natural gas or other fuels, shall be shielded from above in such a manner that the edge of the shield is level with or below the lowest edge of the light source. Where any light source intended for ground illumination is located at a height greater than eight feet, the required shielding shall extend below the lowest edge of the light source a distance sufficient to block the light source from the view of any residential use within 1,000 feet of the light fixture.

2.

Elevated feature illumination. Where lights are used for the purpose of illuminating or accenting building walls, signs, flags, architectural features, or landscaping, the light source shall be shielded so as not to be directly visible from off-site.

E.

Height of light fixtures. Free-standing outdoor lighting fixtures shall not exceed the height of the tallest building on the site.

F.

Street lighting. Street lighting shall be designed to minimize light pollution by preventing the light from going beyond the horizontal plane at which the fixture is directed.
