Summary

Video and animation are banned, each message must hold for at least 5 seconds, and automatic dimming has to keep the display within 0.3 footcandles of ambient light after dark.

(2) Electronic Message Centers. Electronic message centers are allowed subject to the following standards: The electronic message center shall be part of a permanent sign and shall not exceed 32 square feet on each face (maximum of two faces). Electronic message centers shall be included when calculating the allowable square feet that is permitted in a sign code zone district. (a) Electronic message centers are permitted to contain words and/or graphics only. Animation such as video is prohibited. (b) Any words or graphic scrolling or otherwise displayed on an electronic message board shall remain illuminated and visible for a minimum of 5 seconds. (c) The message shall not flash. Any message that remains visible for less than 5 seconds shall be considered to be flashing. ... (f) All permitted EMCs shall be equipped with a sensor or other device that automatically dim according to ambient light conditions. In no case shall the EMC exceed 0.3 footcandles over ambient lighting conditions.

Full Breakdown

Section 17-6-200(L)(2) governs digital signage under the label Electronic Message Centers (EMCs) and treats it as an add-on to a permanent sign rather than a sign type of its own: an EMC cannot exceed 32 square feet on each face, with a maximum of two faces, and its area counts toward whatever total square footage the property's sign-code zone district allows. Content is restricted to words or graphics; § 17-6-200(L)(2)(a) bans animation, including video. Each displayed message, including anything that scrolls, must stay lit and visible for at least 5 seconds under § 17-6-200(L)(2)(b), and § 17-6-200(L)(2)(c) treats anything shown for less than 5 seconds as prohibited flashing.

Brightness is measured, not eyeballed: § 17-6-200(L)(2)(d) requires an illuminance meter accurate to two decimal places, comparing the EMC powered off against the EMC showing a full white, or solid for single-color displays, image, at a measurement distance calculated from the sign's own square footage. Under § 17-6-200(L)(2)(e), that off-to-on difference cannot exceed 0.3 footcandles at night, and § 17-6-200(L)(2)(f) requires every EMC to carry an ambient-light sensor that automatically dims the display so it never exceeds 0.3 footcandles over ambient conditions; exceeding that ceiling is itself a violation under § 17-6-200(L)(2)(g). Safety features are mandatory too: an EMC must default to off or 'full black' on malfunction or a power surge, per § 17-6-200(L)(2)(h). EMCs near a state or federally regulated roadway can face additional state and federal restrictions layered on top of the Village standard.

Violations & Fines

Exceeding 32 square feet per EMC face, running video or animated content, or displaying a message for less than 5 seconds all violate § 17-6-200(L)(2) and can be cited by the Zoning Administrator. Illuminance readings that exceed 0.3 footcandles over ambient conditions, or a missing auto-dim sensor or malfunction failsafe, are separate violations that can force the sign offline until corrected.

Frequently Asked Questions

Can a business in Ashwaubenon install a digital sign?
Yes, as an Electronic Message Center attached to a permanent sign, capped at 32 square feet per face on up to two faces, under § 17-6-200(L)(2). It can't run video or animation and each message must display for at least 5 seconds.
How bright can a digital sign be at night?
The difference between the sign powered off and displaying a full white or solid image cannot exceed 0.3 footcandles, and every EMC needs an ambient-light sensor that automatically dims it to stay within that limit.
What happens if the sign malfunctions?
Section 17-6-200(L)(2)(h) requires the display to automatically turn off or show full black if it malfunctions or a power surge occurs, rather than freezing on a bright or garbled image.
