The WH Overlay District is an overlay district and shall be mapped in combination with one (1) of two (2) underlying districts (R-1-A and R-1-B) and not instead of the underlying districts.
All uses, buildings, and structures permitted in accordance with this chapter and the appropriate regulations of the underlying district with which the mapped WH Overlay District is combined, shall be permitted in the combined districts.
All restrictions and prohibitions provided for by either of the underlying districts combined in accordance with this chapter shall also apply, except as specifically modified by this chapter. Where there is a conflict between this chapter and the underlying zoning, the more restrictive provisions of this title shall govern.
