§ 153.175  OVERLAY DISTRICTS (LC AND LR).
   (A)   Purpose.
      (1)   The original village section of the village is a unique area comprised of residences, neighborhood businesses serving the personal, family, and household needs of residents, offices, and public and semi-public land uses. These uses are contained in structures representing a variety of architectural styles which reflect the era in which most of the original village was constructed. Areas of the original village designated as historic districts are subject to special architectural controls under the Historic Preservation Board.
      (2)   The historical zoning structure within this area fails to adequately reflect the development character and pattern that has occurred over time. Conflicts occur between regulatory structures and historical development trends. The complexity of a mixed-use area cannot adequately be addressed through traditional zoning techniques. In addition, special development standards are necessary to protect the historic architectural character that has developed. To encourage and support this traditional mixed- use environment, the overlay districts are hereby adopted.
      (3)   The overlay districts are comprised of two subdistricts: the Limited Commercial Overlay District (LC) and the Limited Residential Overlay District (LR). Overlay districts are overlay zoning districts and the underlying district standards and requirements shall apply unless where superseded by the LC or LR regulations and requirements.
   (B)   Permitted uses. The following uses are subject to the site plan requirements of this section and architectural requirements under the Historic Preservation Board, as applicable, as well as the general provisions of this Zoning Code. Land and buildings in the Overlay Districts (LC and LR) shall be used only for the following purposes:
      (1)   Limited Commercial Overlay District (LC).

         (a)   Lot area: for residential uses, the minimum lot area shall be 6,000 square feet; for nonresidential uses, no minimum lot area is required; however, the lot area shall be adequate to provide the required yard space;

         (d)   Front yard setback: the minimum front yard setback shall be determined by averaging the existing building lines of the two parcels adjacent to the subject parcel.
