Through lots. A through lot shall be considered as having two street frontages, both of which shall be subject to the front yard requirements of this chapter. Where a lot is bounded on three or more sides by roads, the side opposite the front yard shall be considered the rear yard, and the minimum rear yard setback shall be maintained. The remaining frontage(s) shall be considered the side yard(s), and the front yard setback(s) for the side street(s) shall be maintained, except that the Planning Board may permit parking in these side yard areas, except that in OL Zones this parking shall not be closer than 25 feet to the right-of-way line. Buffer zone requirements established in Chapter 57, Land Development, shall be followed where uses abut a single-family residential zone.
