1193.03   MULTIFAMILY DISTRICTS.
   (a)   Minimum Distance Between Buildings. The minimum distance between any two multifamily dwellings or parts thereof in a development area will vary according to the length and height of buildings. Such minimum distance shall be determined by the following formula:
   Minimum distance (S) = LA + LB + HA + HB 
               f
the elements of such formula being defined as follows:
   "Minimum distance (S)" means the required minimum horizontal distance between any wall of building A and the nearest wall of building B or the vertical prolongation of either.
   "LA" means the total length of building A which, for the purposes of the formula, is defined as the length of the portion or portions of any wall or walls of building A from which lines drawn perpendicular to the face of such wall or walls will interest any wall of building B.
   "LB" means the total length of building B, which for the purposes of the formula, is defined as the length of the portion or portions of any wall or walls of building B from which lines drawn perpendicular to the face of such wall or walls will intersect any wall of building A.
   "HA" means the height of building A.
   "HB" means the height of building B.
   "f" means the division factor, which shall be:
         5 for multi-family - walk-up type
         3 for multi-family - elevator type.
   (b)   Minimum Distance Between Buildings and Side or Rear Lot Lines. A minimum distance between any multi-family dwelling or parts thereof in a development area and any side or rear line of the development area shall vary according to the length and height of the building. Such minimum distance shall be determined by the following formulas: Where land zoned as a Multifamily District abuts Single- Family or Two-Family Districts in AA, A, B, C or D areas:
         Minimum Distance = A + L + H
                   F
Where land zoned as a Multifamily District abuts all other zoned uses:
                  A + L + H
         Minimum Distance =       F   
                     2
the elements of such formula being defined as follows:
   A =    20 feet where the (L) is less than 50 feet and the (H) is less than 30 feet. In all other cases "A" shall be 50 feet.
   L =    length of the property line in feet measured between perpendicular lines to the property line where such perpendiculars touch the extreme ends of the building.
   H =    height of building in feet.
   F =    division factor from the schedules below.
Buildings whose length (L) is up to 100 feet and:
   the height (H) is up to 50 feet             F = 5
   the height (H) is 50.1 to 100 feet             F = 3
   the height (H) is 100.1 to 150 feet             F = 2
   the height (H) is 150.1 and up             F = 1.5.
Buildings whose length (L) is from 100.1 feet to 250 feet and:
   the height (H) is up to 50 feet             F = 3.5
   the height (H) is from 50.1 to 100 feet          F = 2.5
   the height (H) is from 100.1 and up             F = 1.5.
Buildings whose length (L) is 250 feet or more and:
   the height (H) is up to 50 feet             F =   2.5
   the height (H) is from 50.1 to 100 feet          F =    1.5
   the height (H) is from 100.1 feet and up          F=    1.
   When computing the setback formula for buildings of more than one wing, all wings that are within fifteen degrees of being perpendicular to the property line shall be considered as a separate building for measurement purposes.
   All attached wings that are not within fifteen degrees of the perpendicular to the property line shall be considered as one continuous building and the entire length between perpendicular lines to the property line shall be used for determining the length requirement of the formula.
   The required setback shall be measured from the wall plane or point that is the closest to the property line.
   Unless the foregoing formula provides for a greater minimum distance, if land zoned as a Multifamily District abuts a Single-Family or Two-Family District in an AA, A, B, C or D area, the minimum distance between any multi-family dwelling or part thereof located on such land zoned as a Multifamily District shall be no less than:
      (1)   Thirty-five feet from any side or rear line abutting any such Single-Family or Two-Family District if the height of such multifamily dwelling is up to thirty-five feet;
      (2)   Fifty feet from any side or rear line abutting any such Single-Family or Two- Family District if the height of such multifamily building is from thirty-five and one-tenth feet to fifty feet;
      (3)   125 feet from any side or rear line abutting any such Single-Family or Two- Family District if the height of such multifamily dwelling is from fifty and one-tenth feet to 100 feet.
   The rear and side yards shall be open and unobstructed from the ground to the sky and no structure, building or accessory use shall be permitted thereon.
(Ord. 449-69. Passed 10-19-70.)
   (c)   Distances from Main Buildings to Accessory Uses. The minimum distances from any multifamily building to parking areas, driveways, walks and recreation areas and to the development area boundaries, as set forth herein, are intended as desirable criteria and are to be applied in the site planning insofar as possible:

   The minimum distances set forth in the above schedule are intended to be applied to:
            (1)   The main wall, meaning any exterior wall containing the principal windows of a living, dining or sleeping room or rooms.
            (2)   The end wall, meaning any exterior wall, other than a main wall, containing minor windows of a dining or sleeping room, or principal or minor windows of a kitchen or bathroom, or a blank surface.
            (3)   Private streets at all locations except at the garage entrance or main entrance of the dwelling served.
            (4)   Walks used by the public at all locations except at the entrance to the dwelling served.
            (5)   Recreation areas, meaning areas used for active play.
