Number of lots, dwellings or other principal nonagricultural buildings permitted. For each parent tract there shall be permitted the subdivision of one lot (which shall specifically include, but not be limited to, a subdivision to create a farm or farms and a subdivision to change lot lines or a "lot add-on" subdivision which removed land from the parent tract to add the land to another lot) or the erection of one single-family dwelling or other principal nonagricultural building on the parent tract, but not both, with the portion of the existing or newly created lot used for residential or other nonagricultural purposes limited to the maximum lot size set forth in § 301.3A above, for each 25 acres held on March 14, 1978, or if the parent tract was not classified as Rural District or Rural Agricultural District on March 14, 1978, on the date when such land was first included in the Rural District or Rural Agricultural District after March 14, 1978. A tabular example of this limitation on the creation of lots or the erection of dwellings is as follows:
| Parent Tract Size (acres) | Number of Lots Permitted to Be Subdivided or Dwellings or Principal Nonagricultural Buildings Permitted to Be Erected |
|---|
| At least 2 but less than 50 | 1 |
| At least 50 but less than 75 | 2 |
| At least 75 but less than 100 | 3 |
| At least 100 but less than 125 | 4 |
| At least 125 but less than 150 | 5 |
| At least 150 but less than 175 | 6 |
| At least 175 but less than 200 | 7 |
| At least 200 but less than 225 | 8 |
| At least 225 but less than 250 | 9 |
| At least 250 but less than 275 | 10 |
1. The table set forth above shall be followed to determine the number of lots which may be created or the number of dwellings or other principal nonagricultural buildings which may be erected. Whenever possible, each lot shall be created to contain and each dwelling or other nonagricultural building shall be erected on soils with the agricultural land capability classification of IV, V, VI, VII, or VIII as defined by the USDA. If subdivision of a lot with such soils or the location of a dwelling or other principal nonagricultural building upon such soils is not possible, the lot or dwelling or other principal nonagricultural building shall be so located as to be directly adjacent to an existing public road.
2. The number of lots which may be created or single-family dwellings or other principal nonagricultural buildings which may be erected on the parent tract shall be fixed according to the size of the parent tract. This number shall not be increased by the subdivision of such parent tract. Any subsequent owner of a parent tract or land remaining in the parent tract after subdivision shall be bound by the actions of his predecessor.
3. Any land development, the purpose of which is to permit the erection of a permanent single-family dwelling on a parent tract which has been previously improved with a dwelling which also will remain upon the parent tract or to permit the erection of a structure for an additional principal use on the parent tract shall be considered a subdivision for the purposes of this section. It is the purpose and intent of this section to limit the development of agricultural tracts for nonagricultural purposes regardless of whether such development is accomplished by subdivision or land development as those terms are defined in the MPC.
4. No subdivision shall be permitted which shall increase the lot size of a lot of record used or to be used for residential purposes in excess of the maximum lot size as set forth herein. Any lot which is less than 10 acres in size shall be presumed to be used for residential purposes.
5. If a parent tract is to be subdivided to create a new lot for a farm, the remainder of the parent tract and the new lot to be created for the new farm each must contain a minimum of 25 acres.
