§ 152.124 EROSION CONTROL.
   (A)   Slopes. The faces of cut and fill slopes shall be prepared and maintained to control against erosion. This control may consist of effective planting. The protection for the slopes shall be installed as soon as practicable and prior to calling for final approval. Where cut slopes are not subject to erosion due to the erosion-resistant character of the materials, such protection may be omitted.
   (B)   Other devices. Where necessary, check dams, cribbing, rip-rap or other devices or methods shall be employed to control erosion and provide safety. Erosion protection is recommended for all fill and cut slopes and is always required for all fill slopes steeper than 1 unit vertical to 3 units horizontal (33.3% slope).
