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.

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.

County airports and County correctional institutions located in the unincorporated area of the County shall be subject to the following special requirements:
(a) Outdoor lighting at a County airport in an area not regulated by state or federal law, such as a parking lot or outside building, shall be fully shielded and use low pressure sodium or narrow spectrum amber LED or another light source with the same limited spectrum.
(b) Outdoor lighting at a County correctional institution in an area not regulated by state or federal law, such as a parking lot, shall be fully shielded and use low pressure sodium or narrow spectrum amber LED or another light source with the same limited spectrum.

Outdoor recreation, sport courts, or athletic field lighting may be exempted from the shielding, CCT, and hours of operation requirements provided that the following conditions are met:
(a) Facilities in Zone A and Zone B:
(1) Lighting at an outdoor recreational facility may remain on to allow an organized recreational event in progress to be completed, provided the event and the facility are not violating the terms of any permit issued by the County or any law or regulation.
(b) Facilities in Zone C:
(1) The design and installation of lighting for outdoor recreation, sport courts, or athletic fields shall follow the illuminance and uniformity guidelines of the IES according to the appropriate class of play; and
(2) The correlated color temperature of the lighting is ≤ 4,200K as listed on the lamp or luminaire manufacturer specification sheets; and
(3) The luminaires shall utilize internal or external shielding in order to minimize uplight and off-site direct visibility of the light sources. A small amount of uplighting is permitted for those activities where the playing unit (ball, etc.) can exceed the height of the luminaires; and
(4) Field lighting is provided exclusively for the illumination of the surface of play and viewing stands and not for other applications, and shall not exceed 50 percent of the full light output when the field is being utilized for other than practice and tournament play; and
(5) Off-site impacts (spill light/light trespass) shall be limited to ≤ 2.0 vertical footcandles at any of the property lines (based upon maintained lumen values) unless approved otherwise by the building official. A photometric study documenting compliance with the horizontal on-site illuminance level(s) (field, court, etc.) at the IES-recommended calculation height, and the perimeter vertical spill illuminance at 5 feet above the adjacent grade and oriented perpendicular into the site, must be included with the plan submittal; and
(6) Lights must be extinguished by 10:00 p.m. or one hour after the end of play, whichever is later; and
(7) Title 24-compliant timing or central control devices must be installed to prevent the lighting from being left on later than one hour after the facility is occupied.
(Added by Ord. No. 10691 (N.S.), effective 12-18-20)
All lighting attached to fuel canopies within Zone C shall meet the following additional requirements:
(a) The maintained illuminance levels shall not exceed 120 percent of IES- recommended practice for low ambient light zones; and
(b) Luminaires for new and rebuilt canopies are to be recessed or semi-recessed into the canopy and possess a flat lens that resides at ≤ 2.5 inches below the canopy ceiling. Replacement luminaires for existing canopies may be surface mounted as long as there is a flat lens and it resides higher than the bottom edge of the perimeter canopy structure. Neither external nor internal lighting of the perimeter structure is allowed unless it exists at the time this updated ordinance was adopted, and then still needs to be brought into compliance within 10 years from the date of adoption of this ordinance.
(Added by Ord. No. 10691 (N.S.), effective 12-18-20)
An outdoor luminaire in any of the following categories is exempt from the requirements of this chapter:
(a) An outdoor luminaire producing light directly by the combustion of a fossil fuel such as a kerosene lantern or gas lamp.
(b) A luminaire used for a holiday decoration, provided it is used for no more than 60 days in a 12-month period and is off between the hours of 11:00 p.m. and sunrise.
(c) Lighting that illuminates a United States or California flag and the flagpole to which the flag is affixed. All luminaires or combination of luminaires shall be shielded as necessary so that the light source is not visible from the property line. In Zone C, luminaires in excess of 4,050 lumens shall be affixed to the top of the flagpole and be aimed downward.
(d) Outdoor lighting for a facility required by state or federal law to have outdoor lighting that does not comply with this chapter. A person seeking an exemption under this subsection shall request an exemption at that time the person submits the application for the permit required by the County Electrical Code. The applicant shall submit proof along with the application for the permit that demonstrates the applicant is entitled to an exemption under this subsection.
(e) Life-safety luminaires that only operate via battery or generator during a power failure.
(f) Outdoor lighting for a state or federal facility or activity for which there is no practicable alternative that complies with one or more of the specific requirements of this chapter.
