1284.05 SINGLE FAMILY CLUSTER UNITS.
   Within a single family cluster development approved by the Planning Commission, single family cluster dwellings, if any, shall comply with all requirements of the R-L district, except as specifically provided below.
   (a)   General. The design criteria set forth in this section are intended to provide considerable latitude and freedom to encourage variety in the arrangement of the bulk and shape of buildings, open space and landscape features. The single family cluster dwellings may be arranged in various groups, courts, sequences or clusters with open spaces organized and related to the dwellings so as to provide privacy and to form a unified composition of buildings and space. Design criteria for single family cluster units are further established below and in Section 1284.06.
   (b)   Unit Types. Single family cluster dwellings may be unit types variously known as zero lot line, patio, atrium, townhouse, duplex, or triplex, or may even be a specially designed free-standing unit. Within the design criteria established in this chapter, single family cluster dwellings may include any type of dwelling ownership or physical arrangement.
   (c)   Number of Units. Not more than 35 per cent of the total dwelling units within any single family cluster development shall be allocated to single family cluster units. The balance shall be allocated to conventional single family detached dwellings. Not more than 3 single family cluster units may be physically attached via common or adjoining walls.
   (d)   Required Yards. Single family cluster dwellings shall maintain the following yards:
      (1)   Front yard
         A.   Private street or drive: 20 feet from garage door to sidewalk or drive, whichever is closer.
         B.   Cul de sac or loop street: 20 feet from garage door to right of way line.
         C.   Other public street: same front yard as conventional single family.
         D.   Front yards and facades shall be designed to create an interesting and varied streetscape.
(Ord. 53-97. Passed 6-11-97.)
         E.   Minimum building front yard setback: 15 feet to right-of-way line or street pavement edge, whichever is greater.
            (Ord. 131-06. Passed 2-26-07.)
        (2)   Rear yard: 15 feet from any open space area and 50 feet from any conventional single family property line, inside or outside the single family cluster development. Where the single family cluster dwelling is adjacent to common open space with a minimum dimension of 50 feet, an open porch may extend to within 5 feet of the open space area.
         (Ord. 53-97. Passed 6-11-97.)
      (3)   Side yard: a minimum of 5 feet, with a minimum of 10 feet between adjacent buildings. On cul-de-sac lots, there will be a minimum of 3 feet and 7 feet, as per Exhibit A, on file with the Planning Commission.
         (Ord. 127-06. Passed 2-12-07.)
      (4)   The Planning Commission may modify the above required yards to provide greater or lesser distances in order to achieve the objectives stated in Section 1284.01.
   (e)   Parking. Within groups of single family cluster units, additional guest parking shall be provided at a ratio of one space for each 5 such units. Additional guest off-street parking areas may be required by the Commission if it determines that such additional parking is necessary to adequately serve the needs of the cluster area.
   (f)   Floor Area. Single family cluster dwellings shall comply with the same minimum floor area requirements as the R-L District in Section 1252.05(g).
   (g)   Lot Coverage. Single family cluster dwellings and lots shall be exempt from the lot coverage limitation in Section 1280.06(d).
