   (B)   Outside of the city and within one and one-half miles of the city limits, the following shall be required:
      (1)   In subdivisions provided with both an approved community water supply system and an approved community sanitary sewer and sewage treatment system at the time of final plat approval, lot width and area for the district in which the subdivision is located shall be not less than as provided in the Mattoon Zoning Ordinance.
      (2)   In subdivisions not served by an approved community sanitary sewer and sewage treatment system at the time of final plat approval, and whether or not the lot is served by an approved community water supply system, lot width and area shall be a minimum of:
         (a)   Eighty feet wide at the setback line and not less than 20,000 square feet in area for single- and two- family residences;

         (d)   Or, of sufficient size and capabilities to meet the recommendations of the Illinois Department of Health and the Coles County Health Department to be able to adequately accommodate both a primary and secondary treatment site and a potable water supply. However, in no case shall a lot governed by division (A) have setback and width requirements less than those standards therein contained for single- and two-family residences.
   (C)   All corner lots shall contain the width necessary to conform to the required setbacks along both roads or streets.
   (D)   All lots shall abut on a publicly dedicated and accepted all-weather road or street meeting the minimum for the classification and requirements herein contained.

In that event a planting strip for a screen at least 20 feet in width shall be provided along the back of the lot.
      (2)   In all other cases where double frontage lots are permitted, vehicular access shall be permitted to only one thoroughfare, and that thoroughfare being of the lower classification. Restrictions as to access shall be indicated upon the face of the plat.
   (H)   The total land area within the boundary of a plat shall be an official part of the plat and accounted for as either lots, tracts, easements, dedicated or reserved public areas, dedicated rights-of-way, or common area.
