§ 19.66  BILLBOARDS.
   (a)   Purpose, intent and findings.
      Billboards are prohibited in all districts and any billboards legally in existence on August 6, 2009, shall have the status of a nonconforming use under M.S. § 462.357, subd. 1e, as it may be amended from time to time. With respect to these nonconforming billboards, the standards of this Article VI and state law apply. The City Council finds it necessary for the promotion and preservation of the public health, safety, welfare and aesthetics of the community that the construction, location, size, conspicuity, brightness, legibility, operational characteristics and maintenance of billboards be controlled. Billboards have a direct and substantial impact on traffic safety, pedestrian safety, community aesthetics and property values. The City Council recognizes that a great percentage of billboards that are blighted, unattractive or provide an unsafe distraction to motorists can be corrected by sensible quality control through adequate maintenance, inspection and operational guidelines. With respect to electronic billboards, the City Council finds that they are highly visible from long distances and at very wide viewing angles both day and night and are designed to catch the eye of persons in their vicinity and hold it for extended periods of time. If left uncontrolled, electronic billboards constitute a serious traffic safety threat. Studies conducted by the Federal Highway Administration (FHWA), Research Review of Potential Safety Effects of Electronic Billboards on Driver Attention and Distraction, September 11, 2001 and The Role of Driver Inattention in Crashes: New Statistics from 1995; the University of North Carolina Highway Safety Research Center, Distractions in Everyday Driving, May 2003 and The Role of Driver Distraction in Traffic Crashes, May 2001; the Wisconsin Department of Transportation, Synthesis Report of Electronic Billboards and Highway Safety, June 10, 2003; the Municipal Research and Services Center of Washington, Sign Control Provisions, Jan. 2006; and the Veridan Group, Video Signs in Seattle, Gerald Wachtel, May 2001, reveal that electronic signs, including billboards, are highly distracting to drivers and that driver distraction continues to be a significant underlying cause of traffic accidents.
      The City Council intends by this section of the city code to establish a legal framework for billboard regulation in the city. The regulations promulgated in this Article VI are intended to facilitate an easy and agreeable communication between people while protecting and promoting the public health, safety, welfare and aesthetics of the community. It is not the purpose or intent of this section of the city code to prefer or favor commercial messages or speech over noncommercial messages or speech or to discriminate between types of noncommercial speech or the viewpoints represented therein. The owner of any billboard which is otherwise allowed by this section of city code may substitute noncommercial copy or message in lieu of any other commercial or noncommercial sign copy or message without any additional approval or permitting subject to the operational standards set forth herein. The purpose of this provision is to prevent any inadvertent favoring of commercial speech or message over noncommercial speech or message. This provision prevails over any more specific provision to the contrary. The purposes of the regulations promulgated in this section include:
      (1)   To eliminate potential hazards to motorists and pedestrians using public streets, sidewalks and rights-of-way;
      (2)   To safeguard and enhance property values;
      (3)   To control nuisances;
      (4)   To protect government investments in public buildings, streets, sidewalks, traffic control and utility devices, parks and open spaces;
      (5)   To preserve and improve the appearance of the city through adherence to aesthetic principles, in order to create a community that is attractive to residents and to nonresidents who come to live, visit, work or trade;
      (6)   To eliminate excessive and confusing sign displays;
      (7)   To implement the city’s Comprehensive Plan;
      (8)   To encourage signs which by their design are integrated with and harmonious to the surrounding environment and the buildings and sites they occupy;
      (9)   To promote the public health, safety and general welfare; and
      (10)   To provide for fair and consistent enforcement of the regulations set forth herein.

         (C)   Brightness. The sign must not exceed a maximum illumination of 5,000 nits (candelas per square meter) during daylight hours and a maximum illumination of 500 nits (candelas per square meter) between dusk to dawn as measured from the sign’s face at maximum brightness.
         (D)   Dimmer control. Electronic graphic display signs must have an automatic dimmer control to produce a distinct illumination change from a higher illumination level to a lower level for the time period between one-half hour before sunset and one-half hour after sunrise.
