The purpose of this chapter is to protect the health, safety and welfare of the citizens of this city by regulating the time, place and manner of conduct of special events and by establishing permit requirements for conducting special events as such are herein defined. The City Council finds that special events often exceed the city's capacity to provide usual city services. These city services include, but are not limited to sanitary, fire, police and utility services. The City Council also finds these regulations necessary to ensure that such events are conducted with sufficient consideration given to public safety issues, including, among other things, the impact of these events on parking and vehicular traffic within the city.
