Install gravel construction entrances, 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.Inspection and final acceptance letters. 11.Erosion and Sediment Control (E&SC) permit and a Certificate of Coverage must be obtained before any land disturbing activities occur. A copy of the E&SC permit, the COC and a hard co of copy the plan must be kept on site, preferably in a permits box, and accessible during inspection. 12. When the project is complete, the permittees shall contact DEMLR to close out the E&SC Plan. 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 "...

CONSTRUCTION 1. Use a hand tool such as a mattock or pick to score the ground. Using a shovel, dig the trench to the needed depth. Soil from excavatingthe trenches can be laced on the uphill, or flow side of the trench to be used during installation. P P 9 For soft, loamy soils dig a 3-5 inch trench. For hard, rocky soils dig a 2-3 inch trench. 2. La the first straw wattle snu in the trench. No daylight should be seen under the wattle. Pack soil from trenching Y 99 Y9 against the wattle on the uphill side. When installing running lengths of straw wattles, butt the second wattle tightly against the first. DO NOT overlap the ends. Stake the straw wattles at each end and four foot on center. 3. Stakes should be driven through the middle of the wattle, leaving 2-3 inches of the stake protruding above the wattle. A heavy sediment load will tend to pick the wattle up and could pull it off the stakes if they are driven down too low. It may be necessary to make a hole in the wattle with the pick end of our mattock in order to et the stake through the Y Y p Y 9 9 straw. When straw wattles are used for flat ground applications, drive the stakes straight down; when installing wattles on slopes, drive the stakes perpendicular to the slope. 4. Drive the first end of the stake of the second wattle at an angle toward the first wattle in order to help abut them tightly together.
