The following prohibitions on signs shall apply in all zoning
districts:
A. Any moving object used to attract attention to a commercial use is prohibited. However, certain flags and banners may be allowed as provided in §
285-51.
B. Flashing, blinking, twinkling, animated, scrolling or moving signs
of any type are prohibited. No sign may display electronically moving
images. Signs may change their message from time to time, provided
that each message is visible for a minimum of six seconds, except
as follows: time and temperature signs may change more frequently,
and a sign with a sign area greater than 30 square feet shall not
change its message more frequently than once every 20 seconds.
(1) In addition, flashing lights visible from a street shall not be used to attract attention to a business. This restriction specifically includes window signs, but does not prohibit Christmas lighting or displays, within §
285-51.
(2) Electronically changeable message signs shall not be allowed in a
residential district.
C. Signs which emit smoke, visible vapors or particles, sound or odor
are prohibited.
D. Signs which contain information that states that a lot may be used
for a purpose not permitted under this chapter are prohibited.
E. Signs that are of such form, shape or color that they resemble an
official traffic control sign, signal or device or that have any characteristics
which are likely to confuse or distract the operator of a motor vehicle
on a public street (such as prominent use of the word "danger") are
prohibited.
F. Signs or displays visible from a lot line that include words or images
that are obscene or pornographic are prohibited.
G. Balloons of greater than 50 cubic feet that are tethered to the ground
or a structure for periods of over a day and that are primarily intended
for advertising purposes are prohibited.
H. Floodlights and outdoor lasers for advertising purposes are prohibited.
Any vehicle, trailer or structure to which a sign is affixed
in such a manner that the carrying of such sign(s) no longer is incidental
to the primary purpose of the vehicle, trailer or structure, but instead
becomes a primary purpose in itself, shall be considered a freestanding
sign and shall be subject to all of the requirements for freestanding
signs in the district in which such vehicle, trailer or structure
is located.
Signs advertising a use no longer in existence (other than a
sign relating to a building that is clearly temporarily vacant and
being offered to new tenants or for purchase) shall be removed within
180 days of the cessation of such use.
