To promote the public health, safety and general welfare through reasonable, consistent, and non-discriminatory regulations for the installation and maintenance of signs. This part is intended to preserve free speech, expression, and content neutrality while balancing the need to regulate the secondary effects of signs, particularly those that may adversely impact scenic views; safety for motorists, bicyclists, and pedestrians; and the interests of the public. These regulations are intended to ensure that signs are not overwhelming; are not a distraction or impediment due to brightness, movement, size, or height; and do not create a hazard.
