During mining and reclamation operations, grading and revegetation shall minimize erosion and convey storm water runoff from reclaimed mining areas to natural outlets or interior basins. The condition of the land shall allow sufficient drainage to prevent water pockets or undue erosion. Natural and stormwater drainage shall be designed so as to prevent flooding on surrounding properties and County rights-of-way. Appropriate erosion control measures shall be incorporated into all surface water drainage systems. Grading plans shall be reviewed by the County to evaluate compliance with drainage plan objectives prior to project approval. (§ 2, Ord. 1276, eff. December 6, 2001)
