4.2.3. RMD—RESIDENTIAL MEDIUM DENSITY.
   A.   Intent. The Residential Medium Density (RMD) district is intended to implement the suburban land use character area as defined in the Forward Monroe plan. RMD allows for a neighborhood development pattern and is intended to allow for a mix of housing types, including single family detached, townhouses/attached single family, and may permit compatible uses as permitted in Section 7: Permissible Uses and Standards.
   B.   Standards. The standards that apply to RMD districts, which are intended to promote a neighborhood development pattern, including a mixture of single family detached and attached homes, are defined in Table 4.2.3. below.
   C.   Density. Maximum permitted density is three (3) dwelling units per acre, by-right. A maximum four (4) dwelling units per acre may be approved if an applicant qualifies for Cluster Development.
   D.   Cluster Development. Cluster development within the RMD district is permitted if an applicant consents in writing to the single-family design guidelines as defined in Section 8.7.2., Single Family Design Guidelines. Cluster development shall be a minimum five (5) acres in size. Cluster development allows an applicant to qualify for reduced minimum lot sizes per Table 4.2.3.1. and an increase in permitted density to a maximum of four (4) dwelling units per acre. In accordance with Section 3.4.15., Major Subdivision Preliminary Plat, cluster developments shall meet all requirements for a subdivision site plan and all other applicable City ordinances and this UDO. A cluster development shall be reviewed as a Conditional Rezoning as outlined in Section 4.6., “Conditional Zoning” following the Zoning Map Amendment process outlined in Section 3.4.6., "Zoning Map Amendment (Rezoning)."
      1.   Open Space. Cluster developments shall designate at least 30% of the site for contiguous open space as defined in Section 8.8.E. The locations of the open space shall be reviewed at the time of rezoning and be dependent upon the internal layout of the project and the adjacent uses. Where properties do not require rezoning, open space shall be reviewed as part of the subdivision preliminary plat. Internally located open space may be needed to compliment a conservation subdivision form, while perimeter open space may be needed to provide a transition or separation from an adjacent lower density residential or agricultural use. Open space areas may be used for the buffering required in Section 4.2.3.D.4 of this UDO.
      2.   Connectivity. Neighborhoods are to be interconnected and connect to adjacent neighborhood. Flexibility for connections shall be provided to preserve on-site environmental resources and preservation areas. Internal connections shall occur through streets and multimodal connections.
      3.   Mixture of Housing (Lot) Types. Each cluster development shall contain at least three (3) different housing types from Table 4.2.3.1. No less than 20% and no more than 60% should be provided of one housing type or lot size out of the housing types to be provided:
