Submit a Land Disturbing Permit Application at least 30 days prior to any land disturbing activity occurring. 2. Buffer zones and limits of disturbance must be flagged out in the field. Tree protection fencing should be installed at this step to protect sensitive areas. 3. Organize onsite pre -construction meeting with Drew Blake (919-548-6715), or Justin Hasenfus (919-545- 8344) to review site plan prior to land disturbing activities. Land -Disturbing Permit and Approved Plans will be provided at this meeting. 4. Install all initial temporary erosion control measures according to the approved plans and information discussed during the pre -construction meeting. Minimal clearing may occur in the immediate area of all measures to provide for installation. 5. Contact Chatham County Watershed Protection Department staff to schedule an inspection of all installed measures. 6. Permitted land disturbing activities may begin upon approval of the installed measures. 7. Complete self -inspections weekly and within 24 hours of a 1" or greater rainfall event. Email all inspection reports to Chatham County Watershed Protection Department staff within 24 hours of inspection. 8. Maintain all erosion and sediment control measures in good working order. Silt fence, inlet protection and other similar measures must be cleaned out before they are half full. Clogged silt fence outlets must be refreshed/replaced. Silt fence cannot have holes or tears. 9. Ground cover shall be provided as follows: a. Stabilize basins, diversion ditches, and perimeter slopes with ground cover immediately after installation. b. For all other areas with moderate and/or steep slopes, or areas of concentrated flow, stabilize area with seed and matting if the slope has not been disturbed for a period of seven (7) days. c. Provide ground cover sufficient to restrain erosion on any portion of the site upon which further land -disturbing activity is not being undertaken within fifteen (15) calendar days of temporarily or permanently suspending land disturbing activity. d. Establish permanent ground cover sufficient to restrain erosion immediately following completion of construction or development and/or prior to final inspection. 10. Re -install adequate erosion and sediment control measures and/or increase maintenance frequency where approved measures fail to prevent accelerated erosion, off -site sedimentation, or repetitive non- compliance issues. 11. Measures must be installed at the back of curb to restrict all vehicle access to the construction entrance. All measures must be installed according to the approved plan unless approved in the field by Chatham County Watershed Protection Department staff (approved Field Revision). 12. Modifications to the approved and permitted plans shall be approved, by Chatham County Watershed Protection Department staff only, prior to removal or installation. Contact Chatham County Watershed Protection Department staff to request an inspection and obtain a sign -off on the plans or an approved Field Revision. 13. Once grading and construction activities are complete, permanently stabilize the s ite. 14. If any sediment basins or other measures need converted to permanent stormwater control measures, call Chatham County Watershed Protection Department staff for approval before doing so. Adequate stabilization upslope is needed before any conversions can occur. 15. Once adequate permanent stabilization has filled in with 90 % cover, call Chatham County Watershed Protection Department staff to schedule an inspection. If the permanent stabilization is adequate, Chatham County will instruct that all temporary erosion control measures be removed. 16. A final inspection will be performed confirming all temporary erosion control measures have been removed. 17. Once the final inspection is complete the permit will be closed and no additional ground disturbing activities can occur.
