A. Scope. This chapter establishes regulations for all permanent and temporary signs in the county that are visible from a public right-of-way. This chapter does not apply to signs erected by the county or other government agencies or signs mandated by state or federal law.
B. Purpose. Signs perform an important function in identifying, promoting, and directing members of the public to businesses, events, messages, services, and other matters of public interest. It is the purpose of this chapter to protect the public health, safety, and welfare and to promote a quality visual environment by establishing reasonable standards for the size, placement, height, and other characteristics of signs placed within the county. The regulations established in this sign code are intended to protect and promote free speech, while encouraging and maintaining a consistent community and business climate. The regulations for signs have the objective to protect public safety and welfare by ensuring that signs are designed, constructed, installed, and maintained according to uniform, nondiscriminatory, and content-neutral standards that promote a high quality, comprehensive system of standards and requirements.

(Ord. O-02-25 § 1 (Exh. A))
