(Added by Ord. No. 10691 (N.S.), effective 12-18-20)
Allowed lighting in Zone C shall meet the following standards:
(a) Shielding, Lumen, and Color Requirements
Class I - Color Rendition Important | Class II - Safety and Security | Class III - Decorative/Aesthetic | |
Shielding | - All luminaires shall be fully shielded | - All luminaires >1,000 lumens shall be fully shielded - Full shielding is not required for luminaires ≤ 1,000 lumens | - All luminaires >1,000 lumens shall be fully shielded - Full shielding is not required for luminaires ≤ 1,000 lumens |
Maximum Light per Site1 (50,000 lumens per gross acre)2 | - 100% of the maximum allowed lumens per site | - 100% of the maximum allowed lumens per site - Non-fully shielded lighting shall not exceed 10% of the maximum allowed lumens per site or 10% of the 5,000 minimum lumen allowance, whichever is greater | - Irrespective of shielding state, lighting shall not exceed 20% of the maximum allowed lumens per site or 20% of the 5,000 minimum lumen allowance, whichever is greater |
Color | - CCT ≤ 3,000K - Low pressure sodium or narrow spectrum amber LED or another light source with the same limited spectrum | - CCT ≤ 3,000K - Low pressure sodium or narrow spectrum amber LED or another light source with the same limited spectrum | - CCT ≤ 3,000K - Low pressure sodium or narrow spectrum amber LED or another light source with the same limited spectrum |
1. A site may include one or more lots, as determined by the building official. 2. The maximum allowed lumens per site shall be determined by multiplying the gross site acreage by 50,000 lumens (e.g., a 0.5-acre site * 50,000 lumens/acre = 25,000 maximum site lumens). The maximum site lumens is inclusive of all lighting classes. All sites shall be allowed a minimum of 5,000 maximum lumens, regardless of the size of the property. 3. All lumens shall be based upon the initial lumen value of the light source. |
(b) Hours of Operation. All Class I and Class III lighting shall be extinguished two hours after sunset or within 30 minutes after the close of business, whichever is later, until one hour before sunrise, except:
(1) On-premises signs shall be extinguished one hour after sunset until one hour before sunrise, unless the business is operating; and
(2) Off-premises signs shall be extinguished one hour after sunset until one hour before sunrise; and
(3) Outdoor illumination of a sales area, commercial area, assembly area, repair area, or industrial area is allowed when the area is in use and the use is not prohibited by any permit issued by the County or by any law or regulation; and

(c) Signage Requirements. All on-premises signs and off-premises signs shall comply with all of the following provisions:
(1) All signs shall have a luminance of less than or equal to 100 candelas per square meter (nits) between sunset and sunrise. For electronic signs, the luminance shall be measured under the conditions of a full-white display; and
(2) The luminous/illuminated surface area of an individual sign shall not exceed 200 square feet.
(d) Publicly Owned Lighting.
(1) New installations of outdoor lighting on public properties and rights-of-way shall only be installed upon determination by the director of the responsible department that the lighting is necessary for the safety and welfare of the general public, and that the result can only be achieved through the provision of outdoor lighting and not through other passive means, such as reflectorized roadway paint or markers.
(2) All new public lighting shall be regulated with adaptive controls such that the lighting of areas is restricted to times, places, or amounts required for safe occupancy or use.
(Added by Ord. No. 10691 (N.S.), effective 12-18-20)
An applicant for any permit required by the County for work involving an outdoor luminaire, unless the work is exempt as provided in this chapter, shall submit evidence with the permit application that the proposed work will comply with this chapter. The submission shall contain the following:
(a) A map or other drawing showing the location of the property where any outdoor luminaire will be installed.
(b) Plans indicating the location on the property where each type of outdoor luminaire will be installed, indicating the type of fixture.
(c) The specifications for each outdoor luminaire to be installed, including but not limited to manufacturer specification sheets, photometric studies, and drawings.
(d) To be considered complete, the plans and descriptions shall enable the plans examiner to readily determine whether the work will comply with the requirements of this chapter. If the plans examiner cannot determine from the applicant's submission whether the proposed work complies with this chapter, the examiner may reject the application or allow the applicant to submit additional information.
(Added by Ord. No. 9974 (N.S.), effective 4-3-09; amended by Ord. No. 10691 (N.S.), effective 12-18-20)
The outdoor lighting equipment installed at a project site (luminaires, lamps, poles, finishes, controls, etc.) and the locations thereof shall not be substituted or altered in any way from the approved plans (except for the use of prior-approved alternate manufacturers with detailed specifications already listed in the Luminaire & Lighting Control Device Schedule of the approved plans) without first submitting the changes to the County (including updated photometric studies where appropriate) and then receiving written approval. Failure to comply with this requirement can result in penalty action from the County, including administrative citations, civil penalties, and a decline to issue the final Certificate of Occupancy or final Certificate of Completion until the project is brought into conformance with the approved plans, to the satisfaction of County staff.
