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/Energy%2oMineral%20and%2OLand%2OResourees/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 0413.0131, NCGOI 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/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. I.

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 Silt 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 Silt Fence. 6. Inlets downstream of disturbances should be protected; streets should be swept when sediment from the construction activity is present. 7. Details for Silt Fence, Silt Fence Outlets, Construction Entrances and other measures are provided on additional sheets. Erosion and sediment control details are not drawn to scale.

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. Diversion Berms - Diversion berms shall be inspected weekly or after each runoff producing rainfall to insure that they are operating as designed and that there / have been no breaches in the berm. Berms shall not exceed 18" in height, and shall be placed in locations that will not interfere with home construction activities. / Once the house construction is completed and the lot is ready to receive sod, then the berm shall be removed and the material incorporated into the graded lot area and covered immediately with sod. All proper care shall be taken to insure that the berms are installed according to the applicable detail with the berm material compacted sufficiently to insure that the berm remains in place during the course of the construction activities. ' 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 1 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. 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 Sitt 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 properly stabilized.
