Purpose. It is the purpose of these zones to recognize and preserve the character of older, mixed-use areas within the City. These areas generally provide a transitional buffer between established neighborhoods and commercial/industrial uses. It is important that zone requirements and design standards not be sacrificed to allow overdevelopment of properties, as this would negatively impact upon the residential properties within these zones and adjoining residential zones. It is the intent that a single-family dwelling be the preferred use of property, as none of the other permitted uses are to be considered unless all other requirements of this chapter can be met. For example, there is not an automatic or implied right to develop a business use. A business use should only be considered if all the requirements of this chapter, including design standards, can be met. It is the intent that these zones continue to be mixed use, recognizing that all properties are not suitable for conversion.
