A.
Purpose. The performance standards in this section are intended to minimize the potential negative effects that a building, structure or use could have on its surroundings, and to promote compatibility with surrounding uses and areas.
B.
Site Maintenance. For all uses and activities, all areas of a site that are not landscaped, paved or developed shall generally be kept free of debris, including unused fill or building materials. Permitted construction activities, as well as outdoor storage uses that are permitted by this title, shall not be subject to this requirement.
C.
Outdoor Lighting.
1.
All outdoor lighting on private property shall conform to the following requirements:
a.
Light fixtures, excluding illuminated signs, shall have a maximum height of 25 feet above grade, or the height of the nearest main building on the site, whichever is less. Additional height shall be allowed where necessary to provide adequate clearance for vehicular circulation, provided that the light fixture's height is no greater than necessary to provide this clearance.
b.
All light sources, excluding illuminated signs, shall include appropriate shielding to direct light away from the sky, surrounding properties and streets. Reflections or glare outside of the subject property shall be minimized.
c.
For sites that are within or adjacent to a residential district, or are separated by a street from a residential district, no light source shall produce an illumination level in the residential district greater than one-quarter footcandle at any point measured 25 feet horizontally from the subject property. This requirement shall not apply to illuminated signs.
2.
Crime Prevention. The following lighting standards apply to all new structures, except for single-family homes, accessory structures on single-family lots, and accessory structures that do not require a building permit.
a.
Table 26-13-010-1 shows minimum lighting intensities for certain locations on a site and within a building.
Table 26-13-010-1: Minimum Lighting Intensity | |
|---|---|
Location | Minimum Intensity |
Exterior building entrances | 4 foot candles |
Parking areas and pedestrian walkways | 1 foot candle |
Elevators, stairwells, and corridors | 0.5 foot candle |
b.
Details of exterior lighting shall be provided on all plans submitted for city review and approval. Photometric calculations shall be based on the "mean" light output per the manufacturer's values of the specified lamp and luminaire photometry data. The details provided for exterior lighting shall include point-to-point photometric calculations at intervals of not more than 10 feet at ground level.
c.
Transitional lighting shall be incorporated in exterior areas going to and from buildings or uses within a site. Transitional lighting shall be provided for building entrances, recreation/office buildings, swimming pool areas, laundry and mail rooms, covered breezeways, and similar areas as determined by the director of development services.
d.
Trees and shrubs shall not interfere with the distribution of lighting as required by this section.
E.
Air Emissions. No use or activity shall result in the repeated and consistently intolerable emission of excessive odors, dust, fumes, smoke or particulate matter, or in emissions that exceed the requirements or levels enforced by the county's Air Pollution Control District.
F.
Electrical Disturbances. No use or activity shall result in electrical disturbances that are readily discernible at the exterior boundaries of the property on which the use or activity is located, or of the dwelling unit in a dwelling group or multiple-unit building.
G.
Vibration. No use or activity shall generate ground vibration that is readily perceptible at the exterior boundaries of the property on which the use or activity is located. The vibrations that ordinarily occur as the result of an approved construction or demolition activity, as well as the vibrations ordinarily created by motor vehicles, shall be exempt from this requirement.
