• • • Flood Plain Management (d) Fill for construction. Fill shall be adequately compacted and the slopes shall be protected by the use of rip rap, vegetative cover or other acceptable method. The Federal Emergency Management Agency (FEMA) has established criteria for removing the special flood hazard area designation for certain structures properly elevated on fill above the 100 year flood elevation. FDMA's requirements incorporate specific fill compaction and side slope protection standards for multistructure or multi -lot developments. These standards must be investigated prior to the initiation of site preparation if a change of special flood hazard area designation will be requested. (6) Storage of materials and equipment. (a) The storage or processing of materials that are, in time of flooding, flammable, explosive, or potentially injurious to human, animal or plant life is prohibited. (b) Storage of other materials or equipment may be allowed if readily removable from the area within the time available after a flood warning and in accordance with a plan approved by the City Council. (7) Public utilities. All public utilities and facilities such as gas, electrical, sewer and water supply systems to be located in the flood plain shall be flood proofed in accordance with the State Building Code or elevated to above the regulatory flood protection elevation. (8) Public transportation facilities. (a) Railroad tracks, roads and bridges to be located within the Flood Plain Overlay District shall comply with division (1) above. (b) Elevation to the regulatory flood protection elevation shall be provided where failure or interruption of public transportation facilities would result in danger to the public health or safety or where the facilities are essential to the orderly functioning of the area. (c) Minor or auxiliary roads or railroads may be constructed at a lower elevation where failure or interruption of transportation services would not endanger the public health or safety. (9) On -site sewage treatment and water supply systems. Where public utilities are not provided: (a) On -site water supply systems must be designed to minimize or eliminate infiltration of flood waters into the systems; (b) New or replacement on -site sewage treatment systems must be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters and they shall not be subject to impairment or contamination during times of flooding; and
