Dynamic Display
Why are we Changing the Code?
•The City’s current ordinance was developed at a time
when Dynamic Display signs were not envisioned.
•On February 20, 2007, the City Council directed City
Staff to study the effectiveness of the City’s current
sign ordinance and determine what amendments to
the City Code are necessary to effectively regulate
Dynamic Display signs.
Current Regulations
1.Signs which change in color or intensity of
light, flashes, scrolls, or animation are
prohibited.
2.Motion signs are prohibited, including any
sign that revolves, rotates, or has any moving
parts or message.
3.The sign light source is required to be
diffused or directed to eliminate glare and
prevent interference with traffic regulations.
Current Regulations
4.The Code prohibits many of the advanced
features of LED signs capable of displaying
video, animation, and scrolling messages.
5.The Code does not provide the City the
ability to regulate features of LED signs.
6.The Code regulations with respect to
illumination are also insufficient to
effectively regulate LED illumination.
Staff Recommendations
1.Create a Definition of “Dynamic Displays”
2.Create a Time Limit for “Dynamic Displays”
3.Define Brightness Levels
4.Establish Sign Maintenance Regulations
5.Regulate Locations
What is Dynamic Display?
1. Definition
“Dynamic Display”
–A sign or characteristics of a sign that
appear to have movement or that appear to change, caused by
any method other than physically removing and replacing the
sign or its components, whether the apparent movement or
change is in the display, the sign structure itself, or any other
component of the sign. This includes a display that
incorporates a technology or method allowing the sign face to
change the image without having to physically or
mechanically replace the sign face or its components. This also
includes any rotating, revolving, moving, flashing, blinking, or
animated display and any display that incorporates rotating
panels, LED lights manipulated through digital input, "digital
ink" or any other method or technology that allows the sign
face to present a series of images or displays.

3. Brightness Levels
3. Brightness Levels
1.Establish a measurable brightness level.
2.Require signs to be equipped with a mechanism to control
brightness.
3.Establish the city’s authority to disable or turnoff a sign that
malfunctions in a manner that creates excessive glare or
brightness.
4.Establish a requirement for a written certification from the
sign manufacture that the sign has been preset to limit the
maximum light intensity.
5.Require sign owners to provide an accurate field method of
insuring that maximum light levels are not exceeded.
Question?
Should brightness levels be defined by measurable
standards or general terms?
Minnetonka
Measured by general terms
Bloomington
“Measurable Standard”
500 Nits at Night--5000 Nits at Day
Staff Recommendation
•Establish a measurable standard (
500 Nits at Night--5000 Nits at Day)
•Illumination controlled by a mechanism to adjust intensity and brilliance.
4. Sign Maintenance
•Dynamic Displays must be designed and
equipped to freeze the sign face in one
position if a malfunction occurs.
•Dynamic Displays must be equipped with a
means to immediately discontinue the
display.
•The sign owner must immediately turn off
the display when out of compliance.
