1203.03 LOTS.
   (a)   Frontage. Except as provided below, all lots must have frontage on a public street other than a controlled or limited access street. The end width of an existing street shall not be used as frontage as stated in Section 1203.02(b). A parcel of land which was sold on land contract without street frontage prior to 1970 may now be subdivided without street frontage, provided the parcel has access to a public street over a perpetual access easement.
 
   (b)   Minimum Lot Size. Minimum lot sizes in zoned areas, where public and/or community sewer and water is to be utilized shall be as specified in the appropriate zoning code. Lot sizes in zoned areas where sewer, either public and/or community, is not available, shall be as specified below. Minimum lot sizes in areas that are not zoned shall be as specified in Table 1 found in this section. In certain areas where the Planning Board and the City Commission, when involved, deem it necessary, the minimum requirement set forth in Table 1, Column A, found in this section for single-family dwellings may be varied in recognition of an established need for low-cost housing, provided the minimum requirements of the Zoning Code applying to a given tract of land shall be adhered to.
 
   (c)   Maximum Lot Size. No lot shall have a depth which is more than four (4) times its width. In case of a lot not having a uniform width, "width" as used in the preceding sentence shall mean the average of the greatest and least width of such lot. This provision shall not apply to a lot which has an area of more than five (5) acres, has a minimum lot width of 150 feet, and meets all the other requirements of the zoning ordinance and the subdivision regulations.
 
   (d)   Utility Transition Area. If the subdivider chooses to provide water and sewer services in the manner set forth in Section 1211.01 (i), minimum lot size and width shall be as noted in Section 1203.03, Table 1, Column A. If the subdivider chooses to provide temporary water supply and sewage disposal on each individual lot, such lots may be platted in such a manner that in the future each lot may be split into two or more parts, each of which contains the necessary area and frontage as specified in Section 1203.03, Table 1, Column A. The original lot shall have a minimum frontage and lot area as specified in Section 1203.03, Table 1, Column B. The procedure for platting lots in the aforementioned manner is set forth in Chapter 1207.
 
   (e)   Corner Lots. In areas where sewer and water are available the minimum width as measured across the least width of the lot at the building line shall be 85 feet.
 
   (f)   Double Frontage. Double frontage lots other than corner lots shall be prohibited except when the size of the tract, topography, or other circumstances are such that development of the tract without double frontage lots would be impracticable as determined by the Planning Board or when the Planning Board requires them in order for lots adjoining a major traffic artery to have frontage on a minor street in the proposed subdivision. In either of such cases, the right-of-way boundary of the minor street shall constitute the front of any such lots. There shall be no right-of-vehicular access across the rear property line. Such prohibition of vehicular access shall be expressed on the plat, and a release and relinquishment of said right-of-access to the political subdivision having control of such major traffic artery shall be incorporated in the dedication section of the record plan. The minimum depth for a double frontage lot shall be 150 feet.
 
   (g)   Lot Lines. Side lot lines shall be approximately at right angles to the street, or radial to curved streets. Curved side or rear lot lines shall not be permitted.
 
   (h)   Shape. All lots when possible, shall be rectangular in shape. Triangular-shaped lots shall be discouraged.
 
   (i)   Setbacks. Minimum building setback requirements shall be as required in the appropriate zoning code. In unzoned areas, minimum setback requirements shall be as specified below. All required minimum building setback lines for front yards shall be measured from the nearer edge of the existing or proposed, if applicable, right-of-way.
      (1)   Residential Lots. The minimum building setback line shall be 30 feet. The minimum building setback on the side street of a corner lot shall be 25 feet.
      (2)   Business or Industrial Lots. The minimum front setback line on a business or industrial lot shall be 25 feet. The minimum building setback on the side street of a corner lot shall be 20 feet.
      (3)   Exceptions. When the minimum required setback line is greater than that established by existing buildings on contiguous lots on the same street, corner lots excepted, there may be a gradual transition at the rate of two-and- one-half feet or more per lot from the existing to the new. However, on residential lots the minimum setback shall not be less than 15 feet.
