B. Large entertainment venues with two thousand (2,000) to ten thousand (10,000) fixed permanent seats are allowed the following signage:
1. Digital Displays.

b. One digital display is allowed for the primary user. No digital signs are allowed for the secondary user.
c. The maximum display area is one hundred fifty (150) square feet.
d. General advertising for hire is allowed.
e. Digital displays must meet the following criteria:
i. A digital display may show only a series of still images, each displayed for at least eight seconds. The still images may not be animated (i.e., move or present the appearance of motion) and may not use flashing, scintillating, blinking, or traveling lights or any other means not providing constant illumination.
ii. Digital displays must use either an instant transition between still images or a fading transition with a transition time between still images of not less than one second and not more than two seconds. A digital display must not go blank during a transition.
iii. The maximum pixel pitch of a digital display is sixteen (16) millimeters.
iv. Digital displays must be equipped with a sensor or other device that automatically adjusts the brightness of the display according to changes in ambient lighting to comply with a brightness limitation of 0.3 foot-candles above ambient lighting. Digital displays must transition smoothly at a consistent rate from the allowed daytime brightness to the allowed nighttime brightness levels, beginning at forty-five (45) minutes before sunset and ending forty-five (45) minutes after sunset. An automatic photometric sensor must be provided for automatic dimming.
v. Upon the request of the chief building official or designee, the display owner, at the owner's expense, shall have a city-approved testing agency measure the brightness of a digital display as follows:
Step One. Measure the display's brightness at night and during the day by focusing on the direct center of the display from a point that is six feet above grade and twenty (20) feet away from the plane of the display (determined by a line that is within six degrees of a line perpendicular to the plane of the display). If brightness so measured exceeds four hundred fifty (450) candelas per square meter during the night or seven thousand five hundred (7,500) candelas per square meter during the day, then the display's illumination must be adjusted so that it does not exceed four hundred fifty (450) or seven thousand five hundred (7,500) candelas, as applicable.
Step Two. Determine the "measurement distance" using the following formula (the "display area" in the radicand is the area of the display in square feet):
Step Three. Use the following formulas to calculate the display's maximum allowed brightness at night and during the day:
Nighttime Maximum Brightness
Bn = 180,000 ÷ D2
Bn = 180,000 ÷ D2
Bn = the maximum brightness allowed at night
D = the measurement distance calculated in Step Two
Daytime Maximum Brightness
Bd = 3,000,000 ÷ D2
Bd = 3,000,000 ÷ D2
Bd = the maximum brightness allowed during the day
D = the measurement distance calculated in Step Two
Step Four. Measure the display's brightness at night and during the day by focusing on the direct center of the display from a point that is six feet above grade and D feet away (i.e., the measurement distance calculated in Step Two) from the plane of the display as determined by a line that is within six degrees of a line perpendicular to the plane of the display. If a brightness so measured exceeds the applicable maximum brightness calculated in Step Three, then the display's illumination must be adjusted so that it does not exceed that maximum brightness.
f. The hours of operation for digital displays are from dawn to 10:00 p.m. on Sunday, Monday, Tuesday, Wednesday, and Thursday and from dawn to midnight on Friday and Saturday.
g. Based on new or updated information or studies, the city council may amend the standards and other provisions in this section to mitigate effects on the visual environment or on residential properties or other sensitive receptors; to reduce driver distractions or other hazards to traffic; or to otherwise protect and promote the public health, safety, and welfare. The city council may apply the amended standards to existing signs and digital displays.
h. Digital displays are subject to approval by the director. As part of this process, the director shall consult with the chief building official on the design and operational elements of any digital display. When deciding whether to approve the drawings, the director: (i) shall consider all of the factors relating to the proposed digital display and, based on the evidence submitted, make the findings set forth in subsections (E)(1) through (E)(8) of Section 15.148.1110 that apply to the digital display; and (ii) shall not consider the content or graphic design of messages other than to determine legality under federal or state law.

v. The maximum brightness of any digital display is four hundred fifty (450) candelas per square meter during the night and seven thousand five hundred (7,500) candelas per square meter during the day. The brightness of a digital display must be measured as follows, at the display owner's expense, by a testing agency approved by the chief building official or designee:
Step One. Measure the display's brightness at night and during the day by focusing on the direct center of the display from a point that is six feet above grade and twenty (20) feet away from the plane of the display (determined by a line that is within six degrees of a line perpendicular to the plane of the display).
Step Two. Use the following formula to determine the "measurement distance" (the "display area" in the radicand is the area of the display in square feet):
Step Three. Use the following formulas to calculate the display's equivalent maximum brightness during the day and at night:
Equivalent Maximum Nighttime Brightness
Bn = 180,000 ÷ D2
Bn = 180,000 ÷ D2
Bn = the equivalent maximum nighttime brightness
D = the measurement distance calculated in Step Two
Equivalent Maximum Daytime Brightness
Bd = 3,000,000 ÷ D2
Bd = 3,000,000 ÷ D2
Bd = the equivalent maximum daytime brightness
D = the measurement distance calculated in Step Two
Step Four. Measure the display's brightness at night and during the day by focusing on the direct center of the display from a point that is six feet above grade and D feet away (i.e., the measurement distance calculated in Step Two) from the plane of the display as determined by a line that is within six degrees of a line perpendicular to the plane of the display. If a brightness so measured exceeds the relevant equivalent maximum brightness calculated in Step Three, then the display's illumination must be adjusted so that it does not exceed that equivalent maximum brightness.
