Purpose. It is the purpose of these zones to recognize and preserve commercial areas which are specifically intended to provide convenient service to surrounding neighborhoods. Because of the necessary interface with residential zones, it is important that negative impacts be minimized. The intent is that nodes of commercial uses be created and continued sprawl along collector and arterial roadways be prevented. It is important that zone requirements and design standards not be sacrificed to allow overdevelopment or improper utilization of properties, as this would negatively impact upon the character of the commercial area and the stability of adjoining neighborhoods. Strict adherence to design standards is deemed important.
