These regulations shall govern the development of all types of land uses, and it is the intent of these regulations to develop a sound, harmonious, and wholesome community by regulating the design and improvements of all new subdivisions and/or redevelopment projects. These rules and regulations shall be applicable to:
(a) The division of any parcel of land shown as a unit or as contiguous units on the last preceding tax roll, into two or more parcels, sites, or lots, any one of which is less than five (5) acres for the purpose, whether immediate or future, of transfer of ownership.
(b) The improvement of one or more parcels of land for residential, commercial or industrial structures or groups of structures involving the division or allocation of land for the opening, widening or extension of any street or streets; and
(c) The division or allocation of land as open spaces for common use by owners, occupants or leaseholders or as easements for the extension and maintenance of public sewer, water, storm drainage or other public facilities.
(d) The division of a tract of land into five (5) parcels or less fronting upon an existing public street, and where the transfer is to be accomplished by the recording of a deed rather than a plat, requires the approval of the Planning Commission before it can be recorded. Such approval may be accomplished in the manner provided in Section 1103.06 of these Regulations.
