(Ord. 07-015 § 4, 2007)
The requirements of this chapter and the Washington Energy Code apply to outdoor lighting requirements for all developments except one- and two-family dwellings and public street lighting.
(Ord. 07-015 § 4, 2007; Ord. 13-012 § 3, 2013)
The installation of new outdoor lighting or the extension, modification or expansion of existing outdoor lighting is subject to the following requirements:
A. 
All outdoor lights shall include a light source and reflector that controls the light beam so that unshielded light does not extend across any bounding property line between incompatible uses or into the public right-of-way.
B. 
Outdoor lighting fixtures shall be designed so that the light source is shielded at any bounding property line except where topographical characteristics make this impossible.
C. 
Applications for commercial development will be evaluated by the city manager or designee to determine if a lighting plan is required to assess and mitigate impacts. The need for a lighting plan will be based on the scope and scale of the project, compatibility with surrounding uses, and anticipated light impacts. If required, the plan will include the following:
1. 
A site plan showing the location of all outdoor light fixtures.
2. 
The type and method of shielding for each light fixture.
D. 
Lighting designed to accent landscaping features or architectural elements, including the illumination of pole-mounted flags of the United States, shall be concealed or positioned so that the light source is not visible at adjacent property lines.
