   .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.  Required open parking spaces shall be permitted in a driveway having minimum dimensions of sixteen (16) feet wide and twenty (20) feet long, measured from the garage door to the nearest edge of the pedestrian walkway or property line, whichever is the lesser distance.
