Design Guidelines because it incorporates standards such as directing outdoor lighting
downwards, height restrictions on parking lot lights, and limiting illumination levels.
4. The proposed amendment will not cause significant health, safety or welfare concerns,
since the regulations do not alter the density, character, or allowed uses within the City. The
regulations contribute to the welfare of the community by preserving the starry night sky as a
natural resource for all to enjoy.

To establish outdoor lighting regulations that encourage lighting practices and systems that will:
1. Permit reasonable uses of outdoor lighting for nighttime safety, utility, security and enjoyment
while preserving the ambience of night;
2. Curtail and reverse any degradation of the nighttime visual environment and the night sky;
3. Minimize glare and obtrusive light by limiting outdoor lighting that is misdirected, excessive,
or unnecessary;
4. Help protect the natural environment from the damaging effects of night lighting;
5. Meet the minimum requirements of the California Code of Regulations for Outdoor Lighting
and Signs (Title 24, Chapter 6).
Other laws or ordinances may require minimum illumination levels for specific applications and
may conflict with these regulations. In such cases, those laws or ordinances shall govern.
17.23.020 Definitions.
"Foot- candle" is a unit of measure of the intensity of light falling on a surface, equal to one lumen
per square foot or the intensity of light from a standardized candle burning at one foot from a
given surface.
"Low- intensity" means lighting designed to accent architectural features or signs that does not
produce glare, such as tubular neon or LED rope lighting.
"Light pollution" means the night sky glow caused by the scattering of artificial light in the
atmosphere.
17.23.030 Application Requirements.
Whenever a person is required to obtain a building permit, electrical permit for outdoor lighting or
signage, and /or approval of any development project, the applicant shall, as a part of said
application, submit sufficient information to enable the Community Development Department to

application shall include the following:

3. Photometric plans depicting the location of all light poles and building mounted lighting
fixtures and a maximum 10 -foot by 10 -foot grid of both the initial and maintained lighting
levels on the site.
4. The project lighting plan shall be coordinated with any associated landscaping plan to prevent
site planning conflicts.
5. Any other information the Community Development Director may determine is necessary to

17.23.040 Operational Standards.

following regulations:
1. Outdoor lighting shall be directed downward and away from adjacent properties and public
rights -of -way.

the site of the light source.
3. The maximum light intensity on a residential site shall not exceed a maintained value of 10
footcandles, when measured at finished grade.
4. The maximum light intensity on a nonresidential site, except auto sales lots and sports fields,
shall not exceed a maintained value of 10 footcandles, when measured at finished grade.
5. The maximum light intensity on an auto sales lot shall not exceed a maintained value of 40
footcandles, when measured at finished grade.
6. The maximum light intensity on a sports field shall not exceed a maintained value of 50
footcandles, when measured three feet above grade. Baseball field lighting may be increased
to a maintained value of 100 footcandles with approval of the Community Development
Director.
7. Outdoor lighting shall be completely turned off or significantly dimmed at the close of
business hours unless lighting is essential for security or safety (e.g. illumination of parking

through the lowest point of the fixture (See Figure 10). Cutoff fixtures must be installed using
a horizontal lamp position. Lighting fixtures should be of a design that complements building
design and landscaping, and may require architectural review.
2. Outdoor lighting shall be fully shielded or recessed (See Figure 11).
3. Lighting fixtures shall be appropriate in height, intensity, and scale to the use they are
serving. Parking lot lights shall not exceed a height of 21 feet, and wall- mounted lights shall
not exceed a height of 15 feet, from the adjacent grade to the bottom of the fixture. The
Architectural Review Commission can approve an exception to these height standards based
on specific extenuating circumstances.
4. All luminaries mounted on the under surface of service station canopies shall be fully
shielded and utilize flush- mounted canopy fixtures with flat lenses.
