In order to better accommodate within a subdivision of ten or more residential lots
certain natural features such as, but not limited to, sinkholes, streams and topographic
changes, the provisions of this section may be utilized to adjust the minimum required
lot area between lots. In the R/R-A and RS/RS-A districts, up to ten percent of the
platted lots within each phase of a subdivision may contain as little as ninety percent
of the minimum required lot area of the zoning district, as established by Table 17.12.020A,
provided that the average size of all lots within the same recorded phase of the subdivision
is equal to or greater than the standard minimum lot size for the district.
