NCC216788_Site Plan or Location Map_20211208

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/g2OMinerala/g20anda/g2OLanda/g2OResourees/Stormwater/NPDESa/g20
General%2OPermits/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.
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
SEDIMENTATION CONTROL PLAN THAT IS KEPT ON THE PROJECT SITE. RULE 15A
NCAC 04B. 0131 STATES THAT "...DOCUMENTATION SHALL BE ACCOMPLISHED BY
INITIALING AND DATING EACH MEASURE OR PRACTICE SHOWN ON A COPY OF THE
APPROVED EROSION AND SEDIMENTATION CONTROL PLAN OR BY COMPLETING,
DATING AND SIGNING AN INSPECTION REPORT THAT LISTS EACH MEASURE,
PRACTICE OR DEVICE SHOWN ON THE APPROVED EROSION AND SEDIMENTATION

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 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.

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 PHASE 3, PART 2
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. LOTS 230 & 231
The sod should be limed and fertilized as per soil type recommendations and type of grass recommendations when and if possible. FOR
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 H&H CONSTRUCTORS OF FAYETTEVILLE, LLC
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 McLAUCHLIN TWP. HOKE COUNTY
