(1) Based upon mapping by the U.S. Department of Agriculture, the following soil types, or their successor types, shall be considered to be alluvial soils that are subject to the flooding:
(a) Atkins silt loam;
(b) Atkins silt loam, local alluvium;
(c) Huntington silt loam;
(d) Melvin silt loam;
(e) Philo silt loam; and
(f) River wash
(2) The Zoning Officer shall require that a detailed on-site survey be made (by a qualified engineer, soil scientist or qualified sanitarian approved by the Board of Supervisors in accordance with accepted on-site survey techniques) to determine the exact extent and nature of areas susceptible to potential problems of flooding, wetness or pollution before issuing a zoning permit for any proposed use within an alluvial soils area if it is along a waterway segment that was not studied as part of the federal floodplain mapping.
(B) Use regulations. Within any alluvial soils that is determined to be within the 100-year floodplain, the regulations of the 100-year floodplain as provided in the township floodplain ordinance shall apply. See Ord. 43C or its successor ordinance, as codified in Chapter 151 of this code of ordinances.
