Construction sequence will be as follows:
1. Obtain all necessary permits and approvals and hold pre -construction conference.
2. Install Gravel Construction Entrance as shown on plans and details.
3. Install Sediment Fence on all downstream slopes as shown on plans and details.
4. Install Silt Fence Outlets as shown on plans as shown on plans and details .
5. Install Skimmer Basins as shown on plans as shown on plans and details.
6. Install Diversion Berms and Swales as shown on plans and details.
7. Establish ground cover on all remaining disturbed areas. Follow fertilizing, seeding,
and mulching listed in details.
8. Once the construction has been completed and the area stabilized and released by
NCDEQ, the temporary erosion control measures shall be removed
