In the R-M Multiple-Family Residential Districts no building or land, except as otherwise provided in this chapter, shall be erected or used except for one or more of the following specified purposes and shall be permitted subject to the review and approval of the site plan by the Planning Commission. Such review of the site plan is required in order to minimize the possibility of adverse effects upon adjacent property; and furthermore to insure proper relationships between the development features as they relate to: traffic safety, service roads, driveways, parking areas; accessory buildings and uses; open space.
      (1)   All uses permitted and as regulated in the R-1A One-Family Residential Districts.
      (2)   Two-family dwellings.

         (a)   All such hospitals shall be developed only on sites consisting of at least five acres in area.
         (b)   The proposed site shall have at least one property line abutting a major thoroughfare and all ingress and egress for the site shall be directly from the major thoroughfare.
         (c)   The minimum distance of any main or accessory building from bounding lot lines or streets shall be at least 100 feet for front, rear, and side yards for all two story structures. For every story above two the minimum yard distance shall be increased by not less than ten feet.
         (d)   Ambulance and delivery areas shall be obscured from all residential view with a continuous and obscuring masonry wall six feet in height and the wall shall be further subject to the requirements of §§ 154.100 through 154.114, “General Requirements.”

         (b)   All dwellings shall consist of at least 350 square feet of floor area per unit (not including kitchen and sanitary facilities.)
         (c)   Total coverage of all buildings (including dwelling units and related service buildings) shall not exceed 25% of the total site exclusive of any dedicated public right-of-way.
      (6)   Convalescent homes, not to exceed a height of two stories, when the following conditions are met:
         (a)   The site shall be so developed as to create a land-to-building ratio on the lot or parcel whereby for each one bed in the convalescent home there shall be provided not less than 1,500 square feet of open space. The 1,500 square feet of land area per bed shall provide for landscape setting, off-street parking, service drives, loading space, yard requirements, and space required for accessory uses. The 1,500 square foot requirement is over and above the building coverage area.
         (b)   No building shall be closer than 40 feet from any property line.
