In those areas of Whitemarsh Township where an overlay district applies, should the use of an underlying district be utilized, underlying requirements shall apply. For overlay uses, the requirements of the overlay district shall apply, and in the event of a conflict, the overlay district requirements take precedence over those of the underlying zoning district(s). In the case of multiple overlay districts, unless otherwise stated, the most restrictive overlay district requirements apply. Unless otherwise stated in any section of this chapter, Steep Slope, Riparian and Floodplain overlay provisions shall take precedence over all underlying or overlying provisions.
