The intent of the following design criteria is to promote efficient communication through high-quality signing which is clear, legible, attractive, and easy to read while maintaining and enhancing the character of a charming, vital, rural community. Applicants are encouraged to design signs that are compatible with the building's architectural concept with respect to materials, color, lettering, and placement. Unless exempted by EMC §
19.10.050, signs shall not be permitted or installed until the appropriate decision maker has issued a finding of conformance with the criteria of this chapter, including:
A. Quantity. The number and types of sign permitted by zone are regulated by EMC §
19.10.170 through §
19.10.200;
B. Materials.
1. Temporary Signs. The construction of temporary signs is limited to the materials described in the definition of "temporary sign," (EMC §
19.10.030, Definitions). In addition, the temporary sign must also conform to the requirements of this chapter, including but not limited to EMC §
19.10.210 (Temporary signs).
2. Permanent Signs. The exterior face(s) of permanent signs must be manufactured of durable materials that withstand the effects of water and wind including the use of wood, metal, stone, brick, glass, heavy gauge plastics, canvas and/or vinyl. The use of paper, including vinyl coated, is prohibited. The following additional requirements apply to any permanent signs larger than 30 square feet, except for window signs located inside glass:
a. Canvas or vinyl signs must be made of minimum 20-ounce materials with polymeric plasticizers for durability.
b. Sign faces made of canvas, fabric, vinyl or similar pliable materials that are attached to permanent sign structures must be mounted behind a perimeter frame or trim cap so that the edges of the sign face are not exposed, except that flags made of 100 percent spun polyester are exempt from this requirement.
C. Lighting. Lighting shall be subtle and consistent with design and shall not obstruct vision or cause glare on surrounding uses.
1. If external or flood lighting is used, it shall be arranged so that the light source is steady, stationary, shielded from view and directed solely onto the sign without causing glare.
2. Internally Illuminated Signs.
a. Internally illuminated signs shall be constructed with an opaque sign face background with translucent text, symbols and/or logo shields. If the sign owner desires to have the entire sign face visible at night, an external light source may be used to illuminate the sign, subject to the illumination standards in this chapter.
b. In no case may an internally illuminated sign or an electronic changeable copy sign exceed a light output of 50 nits in a residential zone or 100 nits in a nonresidential zone during nighttime hours.
c. Neon sign lighting is allowed in non-residential zones only and shall not exceed 100 nits per sign face. Neon signs with solid backgrounds are not allowed in windows in order to ensure maximum light and visibility through windows.
D. Electronic Changeable Copy Signs. An electronic changeable copy sign is not a separately allowed sign type. The purpose of this section is to regulate the manner in which electronic changeable copy sign technology can be applied to sign types that are otherwise allowed in this chapter. It is not intended to allow more signs or larger signs than otherwise permitted in this chapter. No permit shall issue for an electronic changeable copy sign which does not comply with the following standards:
1. Maximum size: 35 square feet.
2. Density.
a. A maximum of one electronic changeable copy sign per 200 feet of street frontage in all nonresidential zones (HCB and P), not to exceed one sign per parcel;
b. One electronic changeable copy sign per 150 feet of street frontage in the R-2 zone abutting State Route 169, not to exceed one sign per parcel. This is intended for limited commercial operations within residential zones, excluding home occupations and single-family uses;
c. Electronic changeable copy signs must comply with the requirements in EMC §
19.10.090; however, review and approval shall be made by the community development director;
d. Shall meet the standards in EMC § 19.10.090(E)(2); and
e. Electronic changeable copy signs are permitted only in HCB, P and R-2 zones as noted above.
3. Maximum Luminance.
b. Nighttime (one-half hour before sunset to one-half hour after sunrise):
i. All nonresidential zones: 100 nits, except within 500 feet of a residential zone: 50 nits
c. Signs shall include auto-dimming features with light-sensory capabilities to dim the sign to allowable luminance levels during nighttime hours.
4. Motion Limits. No motion except for a fade in of the next message with the fade transition being no more nor less than one second. Fade transition is required rather than instantaneous message changes to avoid sudden or startling flashes of light.
5. Minimum hold between messages: four seconds, plus one second transition fade.
6. Programming. To ensure that ECCS are programmed and continue to operate according to local standards, ECCS shall be designed for local on-site control and programming. The applicant shall provide a written certificate from the sign manufacturer that the nighttime light intensity has been factory preset not to exceed allowable levels under this section, and that this setting is protected from end-user modification by password-protected software or other method that ensures compliance.
