(A) All new development must be:
(1) Designed (or modified) and adequately anchored to prevent floatation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy.
(2) Constructed with materials and equipment resistant to flood damage.
(3) Constructed by methods and practices that minimize flood damage.
(4) Constructed with electrical, heating, ventilation, ductwork, plumbing, and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
(5) Reasonably safe from flooding and consistent with the need to minimize flood damage within the flood-prone area.
(6) Assured to provide adequate drainage to reduce exposure to flood hazards.
(B) Floodplain developments must not adversely affect the hydraulic capacity of the channel and adjoining floodplain of any tributary watercourse or drainage system.
(C) Materials that, in time of flooding, are buoyant, flammable, explosive, or could be injurious to human, animal, or plant life shall be stored at or above the flood protection elevation, floodproofed, or protected by structural measures consistent with the standards set forth herein. Furthermore, storage of materials likely to cause pollution of the waters, as defined in M.S. § 115.01, if subject to flooding are prohibited unless adequate safeguards approved by the state water pollution control agency are provided.
