of a limited number of livestock and similar endeavors. Lots must be large enough to offer a
country lifestyle without imposing upon neighboring properties. The minimum lot size and
building locations in this zone must be such that water and sewer facilities and other utilities can
be easily provided on an individual basis on each lot, without adversely affecting surrounding
properties.
