A legal lot, which has been subject to a boundary line adjustment or created through a legally recognized land segregation process and is of sufficient land area to be subdivided at the density applicable to the lot, may be further segregated. However, such further segregation of the lot shall not be permitted if the total number of lots contained within the external boundaries of the lots subject to the original boundary line adjustment or the total number of lots contained within the external boundary of the parcel subject to the original land segregation exceed the density allowed under current zoning. (Ord. 13-19 § 5; Ord. 53-02 § 2 (19A.08.180))
