In all cases where the Wetland Conservation District is super-imposed over another zoning district in the Town of Amherst, that district whose regulations are the more restrictive shall apply.

In the event an area is incorrectly designated as being poorly drained or very poorly drained soils on the Town of Amherst Wetland Conservation District map and evidence to that effect is satisfactorily presented to the Building Inspector or Zoning Administrator, the restriction contained in this section shall not apply.

Conversely, in the event that an area not so designated has poorly drained or very poorly drained soils within the meaning of the aforementioned definition, then the restriction contained in this section shall apply.
