(A) Public utilities. All public utilities and facilities such as gas, electrical, sewer and water supply systems to be located in the floodplain shall be flood-proofed according to the standards in the state’s Building Code or shall be elevated to an elevation above the regulatory flood protection elevation.
(B) Public transportation facilities. Railroad tracks, roads and bridges to be located within the floodplain shall meet the requirements listed in §§ 154.027 and 154.028 of this chapter. The owner or builder of these transportation facilities shall elevate them to at least the regulatory flood protection elevation where failure or interruption of these transportation facilities would result in danger to the public health or safety or where such facilities are essential to the orderly functioning of the area. The city may allow the construction of minor or auxiliary roads or railroads at a lower elevation where the failure or interruption of these secondary transportation services would not endanger the public health, safety or welfare.
(C) Standards for on-site sewage treatment and water supply systems. In instances where the city does not provide public utilities, the following standards shall apply.
(1) The owners and builders of on-site water supply systems must design and construct these systems to minimize or eliminate infiltration of flood waters into the systems.
(2) The owners and builders of new or replacement on-site sewage treatment systems must design and construct these systems to minimize or eliminate:
(a) Infiltration of flood waters into the utility systems; and
(b) The discharges from the utility systems into flood waters.
(3) On-site water supply and sewage treatment systems shall not be subject to impairment or contamination during times of flooding.
(4) The city considers any sewage treatment system designed and constructed according to the state’s current statewide standards for on-site sewage treatment systems to be in compliance with this section.
