No land shall be used or structure erected where the land is held by the Planning and Zoning Commission to be unsuitable for such use or structure by reason of flooding, concentrated runoff, inadequate drainage, adverse soil or rock formation, extreme topography, low percolation rate or bearing strength, erosion susceptibility, or any other features likely to be harmful to the health, safety and general welfare of the community. The Planning and Zoning Commission, in applying the provisions of this section, shall state in writing the particular facts upon which its conclusions are based. The applicant shall have the right to present evidence contesting such determination to the Council if (s)he so desires, whereupon the Council may affirm, modify or withdraw the determination of the unsuitability.
