A grading permit is required for any grading activities that include:
- Any excavation or fill;
- Dredging activities involving wetlands or riparian areas;
- Earthwork, paving, surfacing or other construction that alters an existing drainage pattern of surface water leaving the site, including any change in the direction, velocity or volume of flow;
- Any other grading activity that causes quantities of dirt, soil, rock, debris, or other material substantially in excess of natural levels to be washed, eroded, or otherwise moved from the site, except in compliance with a grading permit.
