B. Basements, as defined by Section 902.02(8)(a) of this <br />Ordinance, shall be subject to the following: <br /> <br /> i. Residential basement construction shall not <br />be allowed below the Regulatory Flood Protection <br />Elevation. <br /> <br /> ii. Nonresidential basements may be allowed <br />below the Regulatory Flood Protection Elevation <br />provided the basement is structurally dry flood <br />proofed in accordance with Section 902.08(4) (c). <br /> <br />C. Ail areas of nonresidential structures including <br />basements to be placed below the Regulatory Flood <br />Protection Elevation shall be flood proofed in accordance <br />with the structurally dry flood proofing classifications in <br />the State Building Code. Structurally dry flood proofing <br />must meet the FP-1 or FP-2 flood proofing classification in <br />the State Building Code and this shall require making the <br />structure watertight with the walls substantially <br />impermeable to the passage of water and with structural <br />components having the capability of resisting hydrostatic <br />and hydrodynamic loads and the effects of buoyancy. <br />Structures flood proofed to the FP-3 or FP-4 classification <br />shall not be permitted. <br /> <br />D. When at any one time more than one thousand (1,000) <br />cubic yards of fill or other similar material is located on <br />a parcel for such activities as on-site storage, <br />landscaping, sand and gravel operations, landfills, roads, <br />dredge spoil disposal or construction of flood control <br />works, an erosion/sedimentation control plan must be <br />submitted unless the community is enforcing a state <br />approved shoreland management ordinance. In the absence of <br />a state approved shoreland ordinance, the plan must clearly <br />specify methods to be used to stabilize the fill on site <br />for a flood event at a minimum of the 100-year or regional <br />flood event. The plan must be prepared and certified by a <br />registered professional engineer or other qualified <br />individual acceptable to the City Council. The plan may <br />incorporate alternative procedures for removal of the <br />material from the floodplain if adequate flood warning time <br />exists. <br /> <br />E. Storage of Materials and Equipment. <br /> <br /> i. The storage or processing of materials that <br />are, in time of flooding, flammable, explosive, or <br />potentially injurious to human, animal, or plant life <br />is prohibited. <br /> <br />9.165 <br /> <br /> <br />
