In cases where the Zoning Board of Appeals considers the information
submitted by the applicant to be insufficient in order to make the
requested determination, the Board will require the applicant to select
a professional engineer(s), hydrologist(s), or soil scientist(s) from
a list provided by the Board, at the applicant's expense, to determine
more accurately the boundaries of the district with respect to an
individual parcel(s) of land.
