Erosion and Sediment Control
Area requiring permanent stabilization | Time frame to apply erosion controls |
Any area that will lie dormant for one year or more | Within 7 days of the most recent disturbance |
Any area within 50 feet of a surface water of the state and at final grade | Within 2 days of reaching final grade |
Any other areas at final grade | Within 7 days of reaching final grade within that area |
Area requiring temporary stabilization | Time frame to apply erosion controls |
Any disturbed area within 50 feet of a surface water of the state and not at final grade | Within 2 days of the most recent disturbance if that area will remain idle for more than 14 days |
For all construction activities, any disturbed area, including soil stockpiles that will be dormant for more than 14 days but less than one year, and not within 50 feet of a surface water of the state | Within 7 days of the most recent disturbance within the area For residential subdivisions, disturbed areas must be stabilized at least 7 days prior to transfer of ownership or operational responsibility. |
Disturbed areas that will be idle over winter | Prior to November 1 or the onset of winter weather, whichever occurs first. |
Note: Where vegetative stabilization techniques may cause structural instability or are otherwise unobtainable, alternative stabilization techniques must be employed. | |
Maximum Drainage Area (acres) to 100 linear feet of silt fence | Range of slope for a drainage area (%) |
0.5 | <2% |
0.25 | > 2% < 20% |
0.125 | > 20% but < 50% |
Area requiring stabilization | Time frame to apply erosion controls |
Any disturbed area within 50 feet of a surface water of the state and not at final grade | Within 2 days of the most recent disturbance if that area will remain idle for more than 14 days |
For all construction activities, any disturbed area, including soil stockpiles, that will be dormant for more than 14 days but less than one year, and not within 50 feet of a stream. | Within 7 days of the most recent disturbance within the area |
Disturbed areas that will be idle over winter | Prior to November 1 |
Note: Where vegetative stabilization techniques may cause structural instability or are otherwise unobtainable, alternative stabilization techniques must be employed. These techniques may include mulching or erosion matting. | |
