CONSTRUCTION SCHEDULE
1. Obtain all necessary permits and plan approvals. Erosion and Sediment Control (E&SC) permit and a Certificate of Coverage (COC) must be obtained before any land disturbing activities
occur. A copy of the E&SC permit, the COC and a hard copy of the plan must be kept on site, preferably in a permits box, and accessible during inspection.
2. Install gravel construction entrances first, then silt fences, reinforced silt fence outlets and wattles.
3. Finish clearing and grubbing any necessary areas on the lots as they are started.
4. Begin lot grading and excavation activities
5. Begin or continue with house construction activities.
6. Finish all rough grading and house construction.
7. Install driveways, walks and patios.
8. Begin fine grading of lot areas
9. Final grassing, mulching and stabilizing of lot. In most cases this will involve the installation of sod on the lot. The silt fence will remain in place until the lot is sodded or grassing is
stabilized and takes hold.
10. The contractor shall conduct self -inspections of the erosion and sedimentation control measures and complete the following combined self -inspection form found on the DEMLR website
https:Hfiles.ne. gov/nedeg/Energya/o2oMinerala/o20anda/o2OLanda/o2OResourees/Stormwater/NPDESa/o2OGeneral%2OPermits/DEMLR-C SW-Monitoring-Forms-Rev-August-8-2019.pdf.
Twelve months of complete inspection forms shall be kept on site and available for inspection at all times. It is recommended a copy be kept in a permits box. (GS 113A-54.1 (e), 15A
NCAC 04B.0131, NCGO1 Part III Sections A and B)
11. Self -inspections for erosion and sedimentation control measures are to be performed at least once every seven calendar days and within 24 hours of every rain event of greater than 1 inch.
Any needed repairs shall be made immediately to maintain measures as designed. All ESC measures shall be maintained as specified in the construction details on this plan. A rain gauge
shall be installed at the project site for monitoring.
12. Inspection and final acceptance letters. When the project is complete, the permittees shall contact DEMLR to close out the E&SC Plan. After DEMLR informs the permittee of the project
close out, via inspection report, the permittee shall visit "deq.nc.gov/NCG01" to submit an electronic Notice of termination (e-NOT). A $100 annual general permit fee will be charged until
the e-NOT has been filled out.
VICINITY MAP (N.T.S.)
MAINTENANCE OF EROSION AND SEDIMENTATION CONTROL MEASURES FOR LOT CONSTRUCTION
Gravel Construction Entrance - The gravel pad should remain in a condition to prevent mud or sediment from leaving the construction site. This may require periodic
topdressing with 2-inch stone. After each rainfall, inspect any structure used to trap sediment and clean it out as necessary. Immediately remove all objectionable
materials spilled, washed, or tracked onto public roadways.
Silt Fence - Sediment fences should be inspected at least once a week and after each rainfall event. Any repairs should be made immediately. Damaged or decomposed
fabric should be replaced promptly. Any sediment deposits that build up against the fence should be removed and disposed of properly to insure that the removed
sediment does not wash back against the fence. Adequate storage volume should be provided for behind the fence at tall times. Take care to not undermine the
fence during cleanout operations.
Sodding - The sod should be properly maintained to insure that the grass take holds in the areas being secured. The sod should be watered as necessary to maintain
adequate moisture in the root zone and prevent dormancy of the sod. The sod should not be mowed to close, since this could inhibit adequate growth and
stabilization of the root bed. The sod should be limed and fertilized as per soil type recommendations and type of grass recommendations when and if possible.
Grassing and Mulching - The area to receive grassing and mulching should be properly fertilized and limed as necessary as an initial step in soil preparation. Once the
grassing has been placed, the area should be maintained as needed to insure that all areas are germinating properly. Any bare areas should be repaired, and
reseeded as soon as possible. If the time of year does not permit the establishment of a permanent grass, then a temporary grassing should be used until the
growing season permits the use of a permanent grass.
Wattles - Wattles shall be inspected after significant rainfall events. Rills or gullies upslope of the wattle and any undercutting is to be repaired. Sediment deposits that
impair the filtration capability of the wattle shall be removed when the sediment reaches one-third of the wattles functional freeboard height. Removed sediment shall
be deposited within the project in such a way that the sediment is not subject to erosion by wind or water.
Reinforced Silt Fence Outlet - Remove sediment deposits as necessary to provide adequate storage volume for the next rain to reduce pressure on the fence/outlet. Take
care to avoid undermining the fence during cleanout. Remove and replace stone as necessary as it becomes clogged with sediment. Remove all fencing materials
and unstable sediment deposits and bring the area to grade and stabilize it after the contributing drainage area has been property stabilized.
General - All measures will be inspected and corrections made after runoff producing rainfalls, or at least once per week minimum. The builder will insure that the
construction activities on any particular lot do not adversely affect any of the installed erosion control measures. If lot construction dictates, measures will be
relocated on the lot to insure that the potential for sedimentation runoff is eliminated as much as possible. Silt fences and gravel construction entrances will be
maintained as suggested in the erosion control manual. Sodding, seeding and mulching will be maintained to insure proper ground stabilizing cover.

Notes:
1. If needed, Tree Protection fencing should be installed along the buffer zone, wetland boundary and/or around
protected trees, providing a radius of at least 1.25 feet for each inch of trunk diameter.
2. Install Silt Fence on the low elevation sides of each lot. Install Silt Fence outlets shown on schematic/diagram and
field adjusted, if necessary, for placement at low points. If lots are contiguous and have different land owners or
builders, each lot should have individual Sift Fences.
3. Install required Silt Fence within 10 feet of property line to ensure there is no conflict with septic system. It is the
responsibility of the builder to ensure the installation of sediment control measures does not impact the septic
system and repair area(s).
4. At least one Construction Entrance/Exit is to be installed per lot.
5. Waste bins and other areas dedicated for managing building material waste shall be at least 50 feet away from
storm drain inlets or drainage ditches unless it can be shown that no other alternative exists. If this separation
cannot be achieved, these areas must be contained behind Sift Fence.
6. Inlets downstream of disturbances should be protected, streets should be swept when sediment from the
construction activity is present.
7. Details for Sift Fence, Silt Fence Outlets, Construction Entrances and other measures are provided on additional
sheets. Erosion and sediment control details are not drawn to scale.
