The purpose of the minor subdivision is to provide an expeditious means of subdivision approval for the annexation of land between existing lots and the adjustment or relocation of one existing boundary line between two adjacent lots or the shifting of boundary lines to increase the area of an existing lot; provided, however, that the lot line change results in the same number of or fewer lots than existed prior to the lot line change; and, provided that all provisions of this chapter and the Zoning Ordinance (Chapter 160) are met. Minor plans may be submitted and processed only for lot line adjustments, simple conveyances, minor subdivisions and minor land developments as characterized in this article, in accordance with the standards and requirements in this section.
