15.28.010 - Purpose

The purpose of this chapter is to establish procedures for regulating signs, including the type, size, location, and construction standards of signs by zone district. The objectives of this chapter include the following:

A. To reinforce that signs should serve primarily to identify the general nature of an establishment or to direct attention to a project, activity, place, person, organization, or enterprise. The use of subordinate information in commercial signage such as telephone numbers, lists of products, pictures of products, etc., is discouraged.

B. As identification devices, signs must not subject the public to excessive competition for their visual attention. As appropriate identification devices, signs should harmonize with the building, the neighborhood, Historic Area, and other signs in the area.

C. The City intends to encourage the installation of signs that improve the appearance of the property and the neighborhood and enhance the economic effectiveness of signs.

D. The provisions in this chapter provide standards to safeguard life, health, property, and public welfare in keeping with the character of the City by regulating the size, height, structural design, quality of materials, construction location, electrification, illumination, and maintenance of all types of signs and sign structures.

E. The requirements and provisions set forth in this chapter shall apply to all signs erected, altered, relocated, repaired, or maintained within the City. No sign shall be erected, repaired, maintained, or relocated except as provided in this chapter.

15.28.110 - Master Sign Programs

The purpose of Master Sign Programs is to harmonize the appearance of signs, in a manner allowing creativity in design and commercial identification, while avoiding extremes of size, color and shape. A Master Sign Program is also used to distribute allowable sign area for multi-tenant buildings and complexes. Master Sign Programs existing at the time of the adoption of this chapter may continue in effect, until modified.

A. Applicability. A Master Sign Program is required in new non-residential developments of six (6) or more separate tenant spaces that will share either the same parcel or structure and use common access or parking facilities.

B. Allowable Modifications. A Master Sign Program may provide for exceptions from the standards of this chapter, subject to Sonora Municipal Code Chapter 17.62.

C. Review Authority. All Master Sign Programs are reviewed with a use permit and subject to approval by the Planning Commission, as per the City of Sonora Municipal Code Section 17.62.

D. Required Findings. In order to approve a Master Sign Program, the following findings must be met, in addition to other applicable regulations in this section:

  1. The proposed signs are compatible in architectural style and character with any building to which the signs are to be attached, any surrounding structures and any adjoining signage on the site;

  2. Future tenants will be provided with adequate opportunities to construct, erect, or maintain a sign for identification; and

  3. Directional signage and building addressing is adequate for pedestrian and vehicular circulation and emergency vehicle access.

E. Revisions to Master Sign Programs. The Community Development Director may approve minor revisions to an approved Master Sign Program with a sign permit.

15.28.120 - Design Guidelines and Requirements

All signage in commercial and industrial zones should incorporate attractive design elements consistent with the following, as applicable. For illustrations of selected design guidelines, see Figure 6.

A. Size. Notwithstanding applicable sign standards elsewhere in this chapter, sign size shall be proportionate to the size and scale of the site and/or building upon which the sign is proposed. Sign dimensions as specified in this chapter are maximum allowable dimensions; it may be necessary that signs be smaller than the maximum allowed, in order to be proportionate in size and scale to achieve the design objectives of this section.

B. Color. Colors should be used in coordinated groupings and should be compatible with those colors used in the building or project design. For cabinet- style signs, a dark sign background is preferred with light colored copy (characters/graphics).

C. Lighting Intensity. The light emitted or reflected by a sign, or emitted by a light source, shall be of reasonable intensity and compatible with the architecture of the building and the immediate vicinity. Artificial light sources shall be shielded to prevent light spillage, glare or annoyance to persons on or inside adjoining properties or to public or private rights-of-way.

D. Sign Bases and Frames. Freestanding signs shall be either housed in a frame, or set onto a base, presenting a solid, attractive, and well-proportioned appearance. The size and shape of the frame or base shall be proportionate to the size and mass of the sign and be low profile in design. Guy wires, angle irons, braces and other support or construction elements shall be screened or hidden from view.

E. Sign Copy. Sign copy should be simple and concise without excessive description of services or products. On freestanding signs, sign copy should be designed to contribute to the design of the structure on which it is displayed. In all cases, freestanding sign design and sign copy shall be coordinated to provide an attractively designed freestanding element which identifies the development or project.

F. Maintenance. All signs and their supporting components must be kept in good repair and always maintained in good structural condition. It is unlawful to permit vegetation, rubbish, or flammable material to accumulate within ten feet (10') of any sign.

G. Design Quality. All signs should be professionally designed and manufactured. Signs that utilize hand-made lettering or elements must meet professional standards.

b. The sign face of freestanding and monument signs.

  1. Any awning, structure or facade left exposed after sign, sign face, or sign structure removal shall be repaired to a customary finished appearance.

B. Vacant Buildings and Sites. When a site contains no buildings or contains no occupied buildings, it is the responsibility of the property owner to ensure the following:

  1. No sign or structure that is not exempt by Section 15.28.040 of this chapter shall be constructed, erected, or displayed on a vacant site or on a site with no occupied buildings.
