Environmental hazards must be eliminated as required by the planning commission as follows:
A. No cut or fill slopes shall be constructed in a location or in such a manner that produces a slope face exceeding the critical angle of repose unless, in the opinion of the planning commission, adequate measures will be taken to prevent the soil from moving under force of gravity until such slope is stabilized. All cut and fill slopes shall be covered with topsoil and reseeded to the same extent as the prior existing natural conditions unless, in the opinion of the planning commission, alternative or additional treatment of the slope is necessary to avoid the creation of a significant soil erosion, flood or other environmental hazard.
B. Location of streets and buildings on unstable soil shall be avoided.
C. Surface water produced from the subdivision development shall be properly disposed within the subdivision or shall be drained into natural channels in a manner that will reduce the exposure to flood hazard and will prevent the soil within and outside of the subdivision from eroding, and will not produce an undue flood hazard to adjacent properties.
D. The subdivision layout shall make adequate provision for natural drainage channels and floodways.
E. All water, sewer and other utility systems and facilities located in flood hazard areas shall be designed to minimize infiltration of floodwater into the system, or discharge of the system into the floodwaters.
F. Other environmental hazards must also be eliminated or adequately handled as directed by the planning commission. (Ord. 4-11-79A, 4-24-1979)
