SEED BED PREPARATION: LIMING- Apply lime according to soil test recommendations. If the pH (acidity) of the soil is not known, an application of ground agricultural limestone at the rate of 1-11 2 tons/acre on coarse-textured soils and 2-3 tons/acre on fine-textured soils is usually sufficient. Apply limestone uniformly and incorporate into the top 4-6 inches of soil. Soils with a pH of 6 or higher need not be limed. FERTILIZER- Base application rates on soil tests. When these are not possible, apply a 10-10-10 grade fertilizer at 700 - 1,000 lb/acre. Both fertilizer and lime should be incorporated into the top 4-6 inches of soil. If a hydraulic seeder is used, do not mix seed and fertilizer more than 30 minutes before application. SURFACE ROUGHENING- If recent tillage operations have resulted in a loose surface additional roughening may not be required, except to break up large clods. If rainfall causes the surface to become sealed or crusted, loosen it just prior to seeding by raking, harrowing, or other suitable methods for fine grading. The finished grade shall be a smooth even soil surface with a loosen uniformly fine texture. All ridges and depressions shall be removed and filled to provide the approved surface drainage. Planting is to be done immediately after finished grades are obtained and seedbed preparation is completed. Refertilize if growth is not fully adequate. Reseed, refertilize and mulch immediately following erosion or other damage. In the Piedmont and Mountains, a small-stemmed Sudangrass may be substituted at a rate of 50 lb/acre. DATE:PAGE: NORTH CAROLINA Department of Environmental Quality Effective Date: 9/1/2023 In accordance with the 2013 Design Manual UpdatesTEMPORARY SEEDING NOTES: 1.Permanent seeding, sodding or other means of stabilization are required when all construction work is completed according to the NPDES timeframes table. 2.A North Carolina Department of Agriculture soils test (or equal) is highly recommended to be obtained for all areas to be seeded, sprigged, sodded or planted. 3.Use a seeding mix that will produce fast0growing nurse crops and includes non-invasive species that will eventually provide a permanent groundcover. Soil blankets may be used in lieu of nurse crops. Mat, tack or crimp mulch, as needed to stabilize seeded areas until root establishment. Mulch must cover at leaser 80% of the soil surface. 4.Ground cover shall be maintained until permanent vegetation is established and stable against accelerated erosion. SEED BED PREPARATION: LIMING- Apply lime according to soil test recommendations. If the pH (acidity) of the soil is not known, an application of ground agricultural limestone at the rate of 1 to 1 12 tons/acre on coarse0textured soils and 2-3 tons/acre on fine-textured soils is usually sufficient. Apply limestone uniformly and incorporate into the top 4-6 inches of soil. Soils with a pH of 6 or higher need not be limed. FERTILIZER- Base application rates on soil tests. When these are not possible, apply a 10-10-10 grade fertilizer at 700-1,000 lb/acre. Both fertilizer and lime should be incorporated into the top 4-6 inches of soil.

NON-INVASIVE PERMANENT SEEDING RECOMMENDATIONS FOR LATE WINTER AND EARLY SPRING NON-INVASIVE PERMANENT SEEDING RECOMMENDATIONS FOR SUMMER NON-INVASIVE PERMANENT SEEDING RECOMMENDATIONS FOR FALL DATE:PAGE: NORTH CAROLINA Department of Environmental Quality Effective Date: 9/1/2023 In accordance with the 2013 Design Manual UpdatesPERMANENT SEEDING CONSIDERATIONS FOR CONSTRUCTION SCHEDULING CONSTRUCTION ACTIVITY SCHEDULE CONSIDERATION CONSTRUCTION ACCESS: Construction entrance, construction routes, equipment parking areas. First land-disturbing activity- Stabilize bare areas immediately with gravel and temporary vegetation as construction takes place. SEDIMENT TRAPS AND BARRIERS: Basin traps, sediment fences, and outlet protection. Install principal basins after construction site is accessed. Install additional traps and barriers as needed during grading. RUNOFF CONTROL: Diversions, perimeter dikes, water bars, and outlet protection. Install key practices after principal sediment traps and before land grading. Install additional runoff-control measures during grading. RUNOFF CONVEYANCE SYSTEM: Stabilize streambanks, storm drains, channels, inlet and outlet protection, and slope drains. Where necessary, stabilize streambanks as early as possible. Install principal runoff conveyance system with runoff-control measures. Install remainder of system after grading. LANDING CLEARING AND GRADING: Site preparation- cutting, filling and grading, sediment traps, barriers, diversions, drains, and surface roughening. Begin major clearing and grading AFTER principal sediment and key runoff-control measures are installed. Clear borrow and disposal areas only as needed. Install additional control measures as grading progresses. Mark trees and buffer areas for preservation. SURFACE STABILIZATION: Temporary and permanent seeding, mulching, sodding and riprap. Apply temporary or permanent stabilization measures immediately on all disturbed areas where work is delayed or complete. BUILDING CONSTRUCTION: Buildings, utilities, and paving.Install necessary additional erosion and sedimentation control practices as work takes place. LANDSCAPE AND FINAL STABILIZATION: Topsoiling, trees and shrubs, permanent seeding, mulching, sodding, and riprap. Last construction phase: Stabilize all open areas, including borrow and spoil areas. Remove and stabilize all temporary control areas. NOTE: The above are the main aspects of a typical construction sequence in general terms. A detailed Construction Sequence should be site specific based on your project and site needs. As a minimum, the construction sequence schedule should show the following: ·The erosion and sedimentation control practices to be installed, ·Principal development activities, ·What measures should be in place before other activities are begun, and ·Compatibility with the general construction schedule of the contract. Many timely construction techniques can reduce the erosion potential of a site, such as (1) shaping earthen fills daily to prevent overflows and (2) constructing temporary diversions ahead of anticipated storms. These types of activities cannot be put on the construction sequence schedule, but should be used whenever possible.

Notes: 1.Construct the sediment barrier of standard strength or extra strength synthetic filter fabrics. 2.Ensure that the height of the sediment fence does not exceed 24 inches above the ground. (Higher fences may impound volumes of water sufficient to cause failure of the structure) 3.Construct the filter fabric from a continuous roll cut to the length of the barrier to avoid joints. When joints are necessary, securely fasten the filter cloth only at a support post with 4 feet minimum overlap to the next post. 4.Support standard strength filter fabric by wire mesh fastened securely to the upslope side of the posts. Extend the wire mesh support to the bottom of the trench. Fasten the wire reinforcement, then fabric on the upslope side of the fence post. Wire or plastic zip ties should have a minimum 50 pound tensile strength. 5.When a wire mesh support fence is used, space posts a maximum of 8 feet apart. Supports should be driven securely into the ground a minimum of 24 inches. Wire mesh should be a minimum 14-gauge with 6 inch mesh spacing. 6.Extra strength filter fabric with 6 foot post spacing does not require a wire mesh support fence. Securely fasten the filter fabric directly to posts. Wire or plastic zip ties should have a minimum of 50 pound tensile strength. 7.Excavate the trench approximately 4 inches wide and 8 inches deep along the proposed line of the posts and upslope from the barrier. 8.Place 12 inches of fabric along the bottom and side of the trench. 9.Backfill the trench with soil placed over the filter fabric and compact. Thorough compaction of the backfill is critical to silt fence performance. 10.Do not attach filter fabric to existing trees. 11.Do not place across ditches, streams, or any other areas of concentrated flow. Maintenance: 1.Inspect all measures at least weekly and after each rainfall of 1.0 inch or greater. Make any required repairs immediately. 2.Should the fabric of a sediment fence collapse, tear, decompose, or become ineffective, replace it promptly. 3.Remove sediment deposits as necessary to provide adequate storage volume for the next rain and reduce pressure on the fence. Take care to avoid undermining the fence during cleanouts. 4.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.

The foundation should be excavated at least 2 inches below the crest of the storm drain. Place the bottom row of blocks against the edge of the storm drain for lateral support and to avoid washouts when overflow occurs. If needed, give lateral support to subsequent rows by placing 2 inch x 4 inch wood studs through block openings. 2.Carefully fit hardware cloth or comparable wire mesh with 1/2-inch openings over all block openings to hold gravel in place. 3.Use clean gravel 1/2 to 3/4 inch in diameter, placed 2 inches below the top of the block on a 2:1 slope or flatter and smooth it to an even grade. NCDOT #57 washed stone is recommended. SEDIMENT MAINTENANCE: 1.Inspect all measures at least weekly and after every rainfall of 1.0 inch or greater; repair immediately. 2.Remove sediment as necessary to provide adequate storage volume for subsequent rains. 3.When the contributing drainage area has been adequately stabilized, remove all materials and any unstable soil, and either salvage or dispose of it properly. Bring the disturbed area to proper grade, then smooth and compact before stabilizing.
