18.31.080 Exterior Light Regulations:
A. Purpose and Policies. All exterior illumination shall be designed so as to minimize excessive glare and light trespass on neighboring properties, especially residential neighborhoods, as well as to reduce the impacts of lighting on night skies. Lighting shall not be used to market or advertise products or services, although it may be used to enhance building, landscaping, or site elements.
B. Design Criteria.
1. Lighting shall be provided at consistent levels with gradual transitions to unlit areas. Avoid creating highly contrasting pools of light and dark areas which can be temporarily blinding.
2. Use pedestrian-scale lighting in areas designed for pedestrian activity.
3. Parking lot light fixtures shall be non-glare and mounted no more than twenty-five feet (25') above the ground to minimize the impact on adjacent properties. All fixtures over fifteen feet (15') in height shall be fitted with a full cut-off shield.
4. All building lights shall be directed onto the building itself or the ground immediately adjacent to it. The light emissions should not be visible above the roof line of the building.
C. Plan. An exterior lighting plan shall be submitted with all development proposals showing lighting type, intensity, spacing, height of light fixtures, and provisions to minimize glare and light trespass onto nearby properties. Luminaire shields or cutoffs shall be used where lighting impacts may result on surrounding properties. (Ord. 2144, 12/9/03)
