§ 160.591  GENERAL REGULATIONS.
   Off-premises signs are allowed with RE2, RE3, RE4, RE5, WM1, WM2, and WM3 forms subject to the following regulations.
   (a)   (1)   Off-premises signs will be allowed a maximum size of 288 square feet except as permitted in § 160.592.
      (2)   Exception: In addition to the allowable signage, temporary extensions are allowed; however, they shall not exceed 5% of the overall sign area.
   (b)    No more than one sign face per direction of facing; no more than two parallel sign faces on any one sign structure.
   (c)    Signs will be allowed a maximum height of 40 feet and a minimum height of 12 feet.
   (d)   (1)   There will be a minimum setback of 10 feet from any part of the sign.
   (e)    No part of the off-premises sign face or structure will be allowed to exist in or overlap into the required side or rear yard setbacks. The signs shall not be located in or overlap into any required buffer yard.
   (f)    Similar to basics of measuring of this code, all distances will be measured from the closest point of any part of the sign. The sign shall not be within a 600-foot radius of any other off-premises sign intended to be read from the same right-of-way; the sign shall not be within a 600-foot radius of any other off-premises sign intended to be read from a different right-of-way; the sign shall be no closer than 600 feet from any existing off-premises sign on an interstate highway. 
   (g)    Off-premises signs shall be maintained in a safe and legible condition at all times, including the replacement of defective or damaged parts, painting, repainting, cleaning, and other services required for maintenance of the signs. Unsafe signs shall be removed immediately or brought into compliance upon written notice.
   (h)    Abandoned signs shall be removed or brought into compliance within 90 days of written notice from the director of planning and building services.
   (i)    The light from any illuminated sign shall be so shielded, shaded, or directed so that the light intensity shall not adversely affect surrounding or facing premises or safe vision of operators of vehicles on public or private roads.
   (j)    Blinking or flashing lights are prohibited. Electronic message signs are permitted. The message shall be static; animation is prohibited. 
   (k)    The Interstate 229 corridor includes a variety of residential, commercial, and industrial land uses. In addition, several parks included in the Big Sioux River greenway are adjacent to Interstate 229. The rolling topography provides a unique visual image and character to the city. Therefore, this standard is intended to protect the aesthetic qualities of the Interstate 229 corridor. The total number of off-premises sign structures erected to be read primarily from the Interstate 229 right-of-way shall not exceed 21.
