E.
Outdoor accent lighting. Lighting of landscaping, monuments, plaques, flagpoles and
similar installations are exempted from the shielding requirements in Section 17.33.040(a), but
shall be focused directly at the target so that the luminaire does not create a nuisance. Such
lighting shall be designed and installed so that the luminaire points downward toward the target
where possible, emits no more light than is necessary for the task, and is turned off or dimmed
after astrological twilight or within one (1) hour of the business or building’s closing time,
whichever occurs first, unless a safety or security need is demonstrated to the Building
Commissioner.
1.
String lights. Also referred to as festoon lighting. Unless fully shielded, string lights
shall have an output not exceeding fifty (50) lumens per linear foot. Such lighting shall not
exceed, in total, two thousand (2,000) lumens for residential properties and four thousand
(4,000) lumens for nonresidential properties.
2.Landscape lighting. Illumination of landscape features and building façades shall be limited
to luminaires with output not exceeding two hundred and fifty (250) lumens and shall be
installed and oriented so that their light output points directly toward the feature(s) to be
illuminated. Such lighting shall not exceed, in total, two thousand (2,000) lumens for
residential properties and four thousand (4,000) lumens for nonresidential properties.
3.Flags. Any pole-mounted flag illuminated at night shall utilize no more than three (3)
spotlight luminaires per flagpole. Each of these luminaires shall be installed and oriented
so that their light points directly toward the flag(s), incorporate optics to create the
narrowest possible beam, and not exceed six (600) lumens in output.
F.
Lighting Plans. All applications for a building permit for construction that includes
exterior lighting shall include lighting plans showing the location, mounting height, correlated
color temperature (CCT), lumen output, BUG rating (if applicable), shielding description, and
the quantity of all proposed luminaires. For non-residential property, said lighting plan must
also include the proposed schedule of use, including use of timers, dimmers and/or
motion-sensors. The applicant shall provide sufficient information to verify that lighting
conforms to the provisions of this Ordinance. The Building Commissioner shall have the
authority to request additional information in order to confirm compliance with the provisions
of this ordinance.
Section 17.33.040 Prohibitions
The use of the following types of outdoor lighting is prohibited, except as specifically exempted in this
ordinance:

Section 17.33.050 Enforcement
A. Administrative guidance. The Building Commissioner is authorized to promulgate one or
more interpretive documents to aid in the administration and enforcement of this ordinance. The
owner of any lot or property on which a luminaire or sign subject to this Ordinance is located or
proposed to be located shall have the burden of demonstrating that the existing or proposed
luminaire or sign complies with the standards established by this Ordinance. The manufacturer's
specification sheet may be used to establish the lumen level of a luminaire, CCT and, if required,
to verify the use of fully shielded fixture design. Illumination levels may be verified through the
use of manufacturer's photometric data sheet(s) and/or photometric site drawing or through
