(2) The City may permit non-residential basements below the regulatory flood protection elevation provided the basement is structurally dry flood proofed according to the standards listed in Section 1301.05, subdivision 4 c (below) of this Chapter. C. All areas of non-residential structures (including basements) that would be below the regulatory flood protection elevation shall be flood proofed to meet the structurally dry flood proofing classifications in the Minnesota State Building Code. Structurally dry flood proofing must meet the FP-1 or FP-2 flood proofing classification in the Minnesota State Building Code. This flood proofing shall require making the structure watertight with the walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effects of buoyancy. The City does not allow structures in the flood fringe that the owners have flood proofed to the FP-3 or FP-4 classification in the Minnesota State Building Code. The City does not allow residential structures in the flood fringe that the owners have dry -flood proofed to the FP-1 or FP-2 flood proofing classification in the Minnesota State Building Code. d. When at any one time a property owner or contractor wants to locate more than one thousand (1,000) cubic yards of fill or other similar material on a parcel for activities such as on -site storage, landscaping, sand and gravel operations, landfills, roads, dredge spoil disposal or construction of flood control works, the owner or contractor shall submit an erosion/sedimentation control plan to the City for approval. The plan must clearly specify methods that an owner or contractor shall use to stabilize the fill on site for a flood event at a minimum of the 100-year or regional flood event. A registered professional engineer must prepare the plan. The plan may incorporate alternative procedures for removal of the material from the flood plain if adequate flood warning time exists. e. Storage of Materials and Equipment: (1) The City prohibits the storage or processing of materials that are, in time of flooding, flammable, explosive, or potentially injurious to human, animal, or plant life. (2) The City may allow the storage of other materials or equipment if they would be readily removable from the area within the time available after a flood warning is given and according to a plan that the City has approved.
