A. The city will not recommend for approval any plat of a subdivision which does not make adequate provision for storm or floodwater runoff channels or basins. The stormwater drainage system shall be separate and independent of any sanitary sewer system. Storm drainage shall be accommodated in the streets, gutters or retention basins unless otherwise indicated by the city engineer. Subsurface drainage systems shall be discouraged, but where storm sewers are required, the cost shall be borne by the developer for storm sewers to a size of twenty-four inches; if over twenty-four inches in size and determined to be for benefit outside of the subdivision, the costs may be shared, as determined by the city council, but only for that portion determined to be of benefit outside the subdivision.
B. All provisions for drainage control shall comply with the regulations of the city storm drainage master plan and drainage policy, adopted as ordinance, as it from time to time may be amended.
C. The city council may, when it deems necessary for the health, safety, or welfare of the present and future population of the area and necessary to the conservation of water, drainage, and sanitary facilities, prohibit the subdivision of any portion of the property which lies within any one-hundred-year floodplain as determined by the Federal Emergency Management Agency (FEMA). Any development that may be permitted in the floodplain areas shall comply with the floodplain regulations for the city.
D. Floodway areas shall be preserved from any and all destruction or damage resulting from clearing, grading, or dumping of earth, waste material, or stumps, except at the discretion of the city council.
