    3.    Where a property owner dedicates land for public use or right-of-way for roadways where no direct lot access is provided, the total number of lots that can be created on a property through subdivision is calculated by the total parcel size prior to platting divided by the average minimum lot size. The resulting lots, and residential lots created through an administrative land division in subsection 07-18-01(1) of this chapter, may reduce the average minimum lot size by no more than 15 percent.
    4.    The average minimum lot size shall be calculated for the residential lots within each phase of a subdivision.
