In the interest of promoting the general welfare and public safety of the city and recognizing the city should be aesthetically attractive as well as financially prosperous, the City of Norwalk desires to regulate signs in such a way as to establish a compatibility of sign usage with the land use patterns and standards for the zoning district, and to permit such signs which will not, by reason of their size, location, construction or manner of display cause an annoyance or disturbance to citizens, detract from the community’s aesthetic attractiveness, create a hazard, confuse or mislead traffic, obstruct vision necessary for traffic safety, or otherwise endanger the public morals, health or safety.
