§ 8.50.070. Lighting in the Commercial/Industrial Zone.
8.50.070.1 Generally. All outdoor lighting fixtures shall be installed and operated in conformance with this Chapter, and the Uniform Building and Electrical Codes. The following standards are applicable to all outdoor lighting within the Commercial/Industrial Zone:
8.50.070.2 Maximum Lumen and Shielding. All outdoor lighting shall comply with the following lamp lumen limits and shielding requirements:
a.
Fully shielded: 60,000 lumens (or equivalent) maximum;
b.
Shielded: 1,500 lumens (or equivalent) maximum;
c.
Partly shielded: 825 lumens (or equivalent) maximum;
d.
Unshielded: low voltage (24 volts or less) landscape and ornamental lighting;
e.
Prohibition against adjustable light fixture mounts: outdoor lighting fixtures shall be permanently installed so as to maintain the shielding requirements, except that landscape and ornamental lighting may use flexible or adjustable mounting systems.
8.50.070.3 Height Limit. Lights mounted on poles or structures intended primarily for mounting lights shall not exceed a mounting height of 40 percent of the horizontal distance of the light pole from the property line, up to a maximum of 20 feet high, whichever is lower; except that lighting attached to single story building shall not exceed the height of the roof eave. Poles shall be appropriately scaled for small buildings and lots. Fixtures shall be in scale with the proposed height.
8.50.070.4 Total Lamp Power Limit. This subsection applies to all outdoor lighting, whether attached to a building, poles or other structures. The maximum allowable lighting limit per parcel in the Commercial/Industrial Zone shall be determined by multiplying the area (square footage) of the parcel by 0.05, the allowable lamp wattage per square foot of parcel area. Project scale may require closer spacing and lower wattage.
8.50.070.5 Lighting Curfew. Outdoor lighting systems in the Commercial/Industrial Zone shall be turned off or reduced in lighting by at least 50 percent beginning at 10:00 p.m. or close of business, whichever is later, until dawn or the start of business, whichever is sooner. The reduction shall be determined as an overall average for the parcel. When possible, the lighting system shall be turned off rather than reduced in lighting level. Lighting shall be equipped with controls for photocell on and timer off. Exceptions to the lighting curfew are as follows:
a.
When there is only one conforming lighting fixture for the parcel; or
b.
When a law or regulation requires lighting for steps and stairs; or
c.
When, in the opinion of the Planning Director, reduced lighting levels at a given location will cause unacceptable increased risk and design levels must be maintained.
8.50.070.6 Nonconforming Lighting. All outdoor light fixtures existing and legally installed prior to the effective date of this Chapter shall be deemed non-conforming and are exempt from the requirements of this Chapter except that non-conforming lighting fixtures shall not be structurally altered, reconstructed or replaced so as to extend their useful life.
In the event that any non-conforming lighting fixture is structurally altered, reconstructed or replaced, such fixture shall be made to conform to the requirements of this Chapter. Additionally, should it be determined that a non-conforming light fixture results in light trespass, the Planning Director may require that the light be shielded, filtered, redirected, replaced with a less intense light source, removed or a combination thereof, to eliminate light trespass. Alternatively, a variance may be applied for.
