Sec. 656.399.20. - Bulk Standards.

The following Table 2.0, Bulk Standards, summarizes setbacks and height standards for the Riverside Avondale Overlay. In recognition of the historic pattern of residential structures within the Riverside/Avondale overlay, the current existing residential setbacks of structures are hereby deemed the minimum required setback under this overlay and shall not be considered non conforming setbacks. In addition, new construction standards may follow the existing built environment of that particular area when the built environment is considered a contributing structure as defined in Chapter 307 of this Code.

Except for increases for the side yard for the provision of access to the rear yard for parking, the setback may not deviate more than five feet on any side, front or rear. (3) The setback may be less than ten feet in the event the setback does not exceed the average historic setback on the block. An administrative deviation will be required if the setback is less than ten feet and deviates from the average historic setback on the block. The historic setback shall be determined by the established development pattern as determined as follows: (a) By the average setback of contributing structures on adjacent properties. If there is no contributing structure on the adjacent property, the closest property with an accessory structure with a similar use shall be used for determining the setback; (b) In the event the difference between the setbacks of contributing structures on adjacent properties, or the closest property with an accessory structure with a similar use, is ten feet or more, the historic setback shall be determined by the average setbacks of contributing structures on the same side of the block; (c) In the event there are less than four contributing structures on the side of the block, the historic setback shall be determined using the block on the opposite side of the street.
