A. Slopes. Slopes shall be prepared and maintained to control erosion. Slope protection shall be installed immediately upon achieving final grade or as soon as weather permits and prior to approval by the engineer. Where cut slopes are not subject to erosion, due to the nature of the materials, such protection may be omitted.

B. Other Devices. Where necessary, best management practices such as check dams, silt fences, cribbing, riprap, natural buffer areas or other devices or methods as described in the Stormwater Manual for Western Washington as adopted by the city shall be employed to control erosion. Where natural buffer areas are required, no building, clearing, filling, grading, or ditching is permitted within that area except for minor watercourse maintenance when applicable. The natural buffer area as delineated or described shall be preserved and maintained in its natural undisturbed state for erosion and drainage control.

C. Phasing. Clearing of the site shall be phased to minimize erosion on the site. (Ord. 1113-15 § 4; Ord. 810 § 1, 1996).
