Schelling concerning Section 16, "R-5.0", Zero Lot Line District Regulations, relative to Section 16.C, Conditional Uses, specifically to add an additional subsection. The proposed subsection, Section 16.C.6, would allow Single Family detached dwellings to have a minimum front yard of twenty (20) feet as a conditional use when said dwellings are period homes. The current minimum front yard setback in the "R-5.0" - Zero Lot Line District is twenty-five (25) feet. Furthermore, the conditional use would require all lots fronting on one side of a street between two (2) intersecting streets to maintain a twenty (20) foot front yard setback for the entire block. If the amendment is approved, it would allow a minimum front yard setback of twenty (20) feet in the "R-5.0" - Zero Lot Line District as a conditional use for period homes. R:WGENDA\2-17-981AM9706.D0C February 12, 1998 8:55AM An amendment to Section 48.D, specifically the addition of, "A site plan is not required for property zoned R-5.0 Zero Lot Line District" was facilitated by the request for amendments to Section 16.C. The requirement of a site plan for a conditional use under Section 16.C.6 would be difficult due to the nature of single-family development. The site plan requirement would require the developer to tie down specific structures to lots and would allow for no variation in dwelling unit design as the subdivision develops.

C. INITIATION: An application for a Conditional Use Permit may be filed by the owner of, or other person having a contractual or possessory interest in, the subject property.
