A. 
Upon approval in accordance with site plan review procedures set forth in Article XI, a lot having:

Less than the minimum lot size requirements set forth in Section 400.220(1); but
2. 
At least six thousand (6,000) square feet in area, sixty (60) feet in width and one hundred (100) feet in depth may be used for a detached single-family dwelling, provided the lot contains a lot width and an area equal to or greater than the average lot width and average area of all lots located within two hundred (200) feet of the lot.
B. 
For purposes of determining average lot width and average area, only those lots which are within the "SR" District and which are included within the same subdivision as the lot shall be considered. As used in this Section, a "subdivision" shall mean a tract composed of a minimum of six (6) lots depicted on a duly recorded plat. Where a lot is not located within a subdivision, all lots within the "SR" District and which are within two hundred (200) feet of the lot shall be considered. The average area shall be determined in accordance with the calculation process set forth in Section 400.240(C).
C. 
Calculation process for determining average allowable lot size for "SR" Zoning District:
Step 1:
1.
Identify and calculate the area of each applicable lot within two hundred (200) feet of the parcel in question which contains more than six thousand (6,000) square feet, but less than fifteen thousand (15,000) square feet.
2.
Total the area of all existing residential lots from Step 1-1.
3.
Total the number of existing residential lots from Step 1-1.
Step 2:
1.
Calculate the total area of all applicable lots within two hundred (200) feet of the parcel in question which are under six thousand (6,000) square feet.
2.
Divide the total area in Step 2-1 by six thousand (6,000) square feet (number of hypothetical six thousand (6,000) square foot lots in this area).
Step 3:
1.
Total the number of applicable lots over fifteen thousand (15,000) square feet within two hundred (200) feet of the parcel in question.
2.
Multiply number of lots in Step 3-1 by fifteen thousand (15,000) square feet = allowable area for total calculations purposes.
Step 4:
Add steps 1-2, 2-1 and 3-2 = total area (for calculations purposes).
Step 5:
Add steps 1-3, 2-2 and 3-1 = total lots (for calculation purposes).
Step 6:
Step 4/Step 5 = minimum lot size allowable for parcel in question.
D. 
The provisions of Subsections (A) through (C) notwithstanding, the variable and minimum lot dimensions resulting from or found in this Section shall not be applied to restrict:
1. 
Alterations, additions or reconstruction of existing dwellings on any lot having an area greater than five thousand (5,000) square feet and less than fifteen thousand (15,000) square feet.
