(a) Subdivision means all divisions of a tract or parcel of land divided into two or more lots, building sites, or other divisions for the purpose, whether immediate or future, of sale, legacy, or building development, and includes all division of land involving the opening or construction of a new street or change in existing streets, provided, however, that the following shall not be included:
(1) The division of land into parcels greater than five acres where no street right-of-way dedication in involved.
(2) The public acquisition of strips of land for the widening or opening of streets.
(3) A plat amendment of land in cases where plats with final approval had been granted and the lot sizes are increased. In such cases the subdivider shall file with the Engineer an amended plat.
(b) Subdivisions will be divided into two categories: Major Subdivisions and Minor Subdivisions.
(1) Major Subdivision: Any subdivision not classified as a minor subdivision, and requiring new streets or the extension of any off-tract improvements.
(2) Minor Subdivision: Any subdivision of land involving the creation of fewer than five platted lots. Properties that are classified as minor subdivisions shall not be permitted to further subdivide.
(c) Resubdivision. Whenever a developer desires to resubdivide property lot lines on an already approved final subdivision plat, the developer shall first obtain approval for the resubdivision by the same procedures prescribed for the subdivision of land. Resubdivision is a type of subdivision involving any of the following:
(1) Any change in any street layout or any other public improvement;
(2) Any change in any lot line, whether combining lot lines or creating new lots, except where the lot sizes are increased (see plat amendment below);
(3) Any change in the amount of land reserved for public use or the common use of lot owners;
(4) Any change in any easements shown on the approved plat.
