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:Hff les.nc.gov/ncdeg/Energy%20Mineral%20and%2OLand%2OResources/Stormwater/NPDES%20
General%20Permits/DEMLR-CSW-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.ne.gov/NCGO1" 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.
A "SELF -INSPECTION REPORT FOR LAND DISTURBING ACTIVITY AS REQUIRED BY
NCGS 113A-54.1 "IS AVAILABLE FOR USE. IT CAN BE COMPLETED BY HAND OR
COMPLETED AS AN EXCEL SPREADSHEET.
AN ALTERNATIVE IS TO MAKE NOTATIONS ON THE COPY OF THE APPROVED
EROSION AND

MAINTENANCE OF EROSION AND SEDIMENTATION CONTROL MEASURES FOR LOT CONSTRUCTION TOTAL DISTURBED ACREAGE: 1.47 ACRESLOT EROSION CONTROL PLAN
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 LOTS 14, 15 & 58-60
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. ELLIOT FARMS, PHASE 1 B
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. FOR
Silt Fence - Sediment fences should be inspected at least once a week and after each rainfall event. An repairs should be made immediately. Damaged or decomposed fabric should be replacedpromptly. An sediment deposits that build u against the fence should be removed and disposed of properly to insure
p y p y g p p y p p g p p p y CAVINESS & CATES BUILDING
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 DEVELOPMENT CO.
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.
CARVERS CREEK TOWNSHIP CUMBERLAND COUNTY
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. SCALE. =rE_ 100' (T K A N H I C S� C A I , [L; N OVEM B ER 2022
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 100 0 50 100 200 400
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. ( IN PENT )
