As construction progresses and the topography is altered, appropriate controls must be constructed or existing controls altered to address the changing drainage patterns. (h) Stabilization of Denuded Areas: Disturbed areas must be stabilized as specified in the tables below, or according to the Ohio EPA NPDES Storm Water Permit Rules, whichever is most restrictive: Any areas that will lie dormant for one (1) year or more Any areas within fifty (50) feet of a stream and at final grade Any other areas at final grade Table 3: Temporary Stabilization Within seven (7) days of the most recent disturbance Within two (2) days of reaching final grade Within seven (7) days of reaching final grade within that area Any disturbed areas within fifty (50) feet of a stream and not at final grade Disturbed areas that will be dormant for more than 21 days but less than one (1) year and not within fifty (50) feet of a stream Disturbed areas that will be idle over winter Within two (2) days of the most recent disturbance if the area will remain idle for twenty-one (21) days or more Within seven (7) days of the most recent disturbance within the area. Prior to the onset of winter weather Where vegetative stabilization techniques may cause structural instability or are otherwise unobtainable, alternative stabilization techniques must be employed. In any case, Temporary or Permanent Stabilization will be properly installed, pursuant to the most recent edition of the Ohio Rainwater and Land Development manual, before the second building permit is issued. (i) Sediment Settling Ponds: Storm water runoff that exceeds the design capacity of sediment barriers and concentrated storm water flows shall pass through a sediment settling facility. 20
