   .030   Minimum Lot Width for Cul-de-Sac and Knuckle Lots. The minimum lot width for cul-de-sac and knuckle lots shall be thirty (30) feet, measured at the building setback.
   .040   Minimum Lot Frontage Width of Flag Lots. The minimum lot frontage width at rights-of-way shall be twenty (20) feet.

   .070   "Front-On" Garages. The minimum setback to any “front-on” garage shall be not less than twenty (20) feet, with a roll-up garage door. However, at least fifty percent (50%) of setbacks to “front-on” garages located on the same block shall be twenty-five (25) feet or more.
   .080   Minimum Dimensions of Parking Spaces.

Except as otherwise provided herein, a solid, decorative-type, masonry wall, landscaped earthen berm, or any combination thereof, totaling not less than six (6) feet in height, shall be provided along, and immediately adjacent to, the site boundary line of any single-family development abutting any arterial highway, any commercial or multiple-family zone boundary, or any alley abutting any such boundary. The height of any such wall and/or berm shall be as measured from the highest finished grade level of the building pad of the dwelling units located nearest any such abutting boundary.
   However, in conditions where a grade separation between any arterial highway and property line occurs at a minimum of six (6) feet, and a minimum setback of twelve (12) feet exists between the single-family development and conditions as stated above, an open, decorative-type wall is permitted, in order to allow and preserve view opportunities.
