This Chapter establishes sign regulations that are intended to:

A.

Support the use of signs to aid orientation, identify businesses and activities, express local history and character, or serve other information purposes; and

B.

Protect the ability of the public to identify uses and premises without confusion by encouraging signs to be designed with a scale, graphic character and type of lighting compatible with the appearance of the buildings or uses identified by signs, as well as other buildings and uses in the vicinity; and

C.

Support the use of signs that are maintained in a safe and attractive condition that do not:

1.

Create distractions that may jeopardize pedestrian or vehicular traffic safety; or

2.

Produce glare that adversely affects residential uses.

D.

Allow adequate avenues for both commercial and non-commercial messages, and protect the constitutionally guaranteed right of free speech; and

E.

Protect the character of the various communities within the County and safeguard the public health and safety.

[Amended 2020, Ord. 3420]

22.20.030 - General Principles.

A.

Applicability.

1.

Applicable codes. In addition to complying with the provisions of this Chapter, all signs must be constructed in accordance with the Uniform Building Code, the Uniform Sign Code, the Electrical Code, the California Manual on Uniform Traffic Control Devices, and all other applicable laws, rules, regulations, and policies.

2.

Applicable County regulations. In addition to complying with the provisions of this Chapter, all signs must comply with other regulations of this Title, including Planning Area Standards (Article 9), Community Planning Standards (Article 10), and the Highway Corridor Design Standards (Section 22.10.095).

B.

Regulatory interpretations. The County shall apply this Chapter in a content-neutral manner. This Chapter shall be interpreted in a manner consistent with the free speech protections guaranteed by the First Amendment to the United States Constitution and Article 1, Section 2 of the California Constitution. The noncommunication aspects of all signs shall comply with the regulations and standards set forth in this Title. "Noncommunicative aspects" includes regulations that do not relate to the content of the sign, including the time, place, manner, location, size, height, illumination, spacing, and orientation of signs.

C.

Message substitution. A non-commercial message of any type may be substituted, in whole or in part, for any duly permitted commercial message; and any non-commercial message may be substituted for any non-commercial message.

1.

No additional approval required. Such substitution of message may be made without any additional approval, permitting, registration, or notice to the County. This provision prevents any inadvertent favoring of commercial speech over non-commercial speech or favoring any non-commercial message over any other non-commercial message.

2.

Limitations. This provision does not allow the following:

a.

Create the right to increase the total amount of signage for a parcel, lot, or land use;

b.

Affect the requirement that a sign structure or mounting device be properly permitted; or

c.

Allow a change in the physical structure of a sign or its mounting device.

D.

Nothing in this Section shall be construed to prohibit a person from holding a sign while picketing or protesting on public property that has been determined to be a traditional or designated public forum, so long as the person holding the sign does not block ingress and egress from buildings, create a safety hazard by impeding travel, or violate any other reasonable time, place, and manner restrictions adopted by the County.

E.

Severability. If any section, sentence, clause, phrase, word, portion, or provision of this Chapter is held invalid, unconstitutional, or unenforceable by any court of competent jurisdiction, such holding shall not

affect, impair, or invalidate any other section, sentence, clause, phrase, word, portion, or provision of this Title which can be given effect without the invalid portion. In adopting this Title, the Board of Supervisors affirmatively declares that it would have approved and adopted the Title even without any portion which may be held invalid, unconstitutional, or unenforceable.
