When making its decision to approve or deny a conditional use permit, the planning commission shall consider the impacts upon surrounding uses, schools, including, but not limited to, other similar uses, schools, churches and residential uses, as well as the extent of available on-site parking and other site characteristics.

In its review of a conditional use permit request, the planning commission may consider and specify conditions to deter outdoor congregation by patrons, to limit the hours and method of operation in order to achieve land use compatibility and to discourage illegal or undesirable activities. The city's regulation of hours shall not conflict with regulation by the Alcoholic Beverage Control Board.

Any late-night business within three hundred feet of a residential zone, residential use, church or school in existence and lawfully operating before December 30, 1984, is a legal nonconforming use. The planning commission may at any time require that a particular legal nonconforming late-night business obtain a conditional use permit if it determines that such business is being operated in such a manner that it creates a nuisance to surrounding uses. The planning commission may also require a conditional use permit for any late-night business located further than three hundred feet from the business's exterior property line from the closest residential school or church property line, if it determines that such business is being operated in such a manner that it creates a nuisance to surrounding uses.

Possession of and compliance with a conditional use permit for any late-night business issued by the city before December 30, 1984, shall constitute compliance with this section.
