An "incidental sign" (hereinafter "such sign or signs" or "the sign" or "a sign") is any sign, handbill, or poster which is placed to advertise or announce a specific event, or which pertains to a particular event or occurrence, or which is not designed or intended to be placed permanently, or which relates to such events or occurrence that are not taking place on the premises on which the sign is located. Examples of such signs include, but are not limited to, signs, handbills, or posters relating to garage sales, political candidates or ballot measures, concerts, "swap meets" and the like.

No person shall paint, mark, or write on, or post or otherwise affix, or erect, construct, maintain, paste, nail, tack or otherwise fasten or affix, any such sign or signs on any sidewalk, crosswalk, curb, street lamppost, pole, bench, hydrant, tree, shrub, bridge, electric light or power or telephone wire pole, or wire appurtenance thereof, or upon any street sign or traffic sign, or upon any other object located within the public right-of-way which is not maintained for the purpose of communications by such signs by the general public.

Regardless of the zone in which any such sign or signs are placed, the total area of any such sign or signs shall not exceed 32 square feet where the frontage is equal to or less than 100 linear feet. Where the frontage is greater than 100 linear feet the total area of any such sign or signs may be increased by one-half of one square foot for each linear foot of frontage in excess of 100 feet.

No such sign or signs shall be affixed to any permanent building, structure or facility by use of glue, mastic, tape or tacks penetrating more than one-half inch in depth. This section shall not apply to signs affixed to portable or freestanding devices.

No such sign or signs shall be constructed, located or situated within the public right-of-way, nor so as to constitute a potential hazard to the public, nor so as to obstruct the sight distances of motorists or pedestrians, nor less than five feet from any property line.

Any person desiring to retrieve a sign removed by city officers or employees may do so upon the payment of an administrative fee as determined by the community development director, not to exceed the actual cost of removing the sign. In lieu of paying such administrative fee, such person may retrieve a sign upon signing a promise to appear upon a citation issued to him or her for violation of this chapter. If a person wishes to contest the fact that a sign was placed in violation of this chapter prior to paying the fine or signing the citation, he or she shall have the right to an administrative hearing before the community development director. If the director finds that the sign was lawfully posted, he shall return the sign without an administrative fee or the issuance of a citation.

Any such sign or signs removed by city officers or employees may be considered abandoned if it is not retrieved within 15 calendar days after the date of such removal, and may be disposed of by the city without liability therefor to any person.
