When joints are necessary, securely fasten the filter cloth only at a support post with overlap to the next post. Hanover Design Services 1123 Floral Pkwy. Wilmington, NC 28403 4. Support standard strength filter fabric by wire mesh fastened securely to the upslope side of the posts using heavy duty wire staples at least 1 inch long, or tie wires. Extend the wire mesh support to the bottom of the trench. 5. When a wire mesh support fence is used, space posts a maximum of 8 fit apart. Support posts should be driven securely into the ground to a minimum of 18 inches. 6. Extra suenglh filter fabric with 6ft post spacing does not require wire mesh support fence. Staple or wire the filter fabric directly to posts. 7. Excavate a trench approximately 4 inches wide and 8 inches deep along the proposed line of posts and upslope from the barrier (figure 6.62a). 8. Backfill the trench with compacted soil or gravel placed over the filter fabric. 9. Do not attach filter fabric to existing trees. Maintenance Inspect sediment fences at least once a week and after each rainfall. Make any required repairs immediately. Should the fabric of a sediment fence collapse, tear, decompose or become ineffective, replace it promptly. Replace burlap every 60 days. Remove sediment deposits as necessary to provide adequate storage volume for the next rain and to reduce pressure on the fence. Take care to avoid undermining the fence during cleanout. 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.

Remove good topsoil from areas to be graded and filled, and preserve it for use in finishing the grading of all critical areas. 3. Scarify areas to be topsoiled to a minimum depth of 2 inches before placing topsoil (Practice 6.04, Topsoiling). 4. Clear and grub areas to be filled to remove trees, vegetation, roots, or other objectionable material that would affect the planned stability of the fill. 5. Ensure that fill material is free of brush, rubbish, rocks, logs, stumps, building debris, and other materials inappropriate for constructing stable fills. 6. Place all fill in layers not to exceed 9 inches in thickness, and compact the layers as required to reduce erosion, slippage, settlement, or other related problems. 7. Do not incorporate frozen material or soft, mucky, or highly compressible materials into fill slopes. 8. Do not place fill on a frozen foundation. due to possible subsidence and slippage. 9. Keep diversions and other water conveyance measures free of sediment during all phases of development. 10. Handle seeps or springs encountered during construction in accordance with approved methods (Practice 6.81, Subsurface Drain). 11. Permanently stabilize all graded areas immediately after final grading is completed on each area in the grading plan. Apply temporary stabilization measures on all graded areas when work is to be interrupted or delayed for 30 working days or longer. 12. Show topsoil stockpiles, borrow areas, and spoil areas on the plans, and make sure they are adequately protected from erosion. Include final stabilization of these areas in the plan. Maintenance Periodically check all graded areas and the supporting erosion and sedimentation control practices, especially after heavy rainfalls. Promptly remove all sediment from diversions and other water -disposal practices If washouts or breaks occur, repair them immediately. Prompt maintenance of small eroded areas before they become significant gullies is an essential part of an effective erosion and sedimentation control plan. .

Wilmington, NC 28403 Outlet Stabilization Structure Specifrcatiosr # 6.41 Construction Specifications 1 Ensure that the subgrade for the filter and riprap follows the required lines and grades shown in the plan. Compact any fill required in the subgrade to the density of the surrounding undisturbed material. Low areas in the subgrade on undisturbed soil may also be filled by increasing the nprap thickness. 2. The riprap and gravel filter must conform to the specified grading limits shown on the plans. 3. Filter cloth, when used, must meet design requirements and be properly protected from punching or tearing during installation. Repair any damage by removing the riprap and placing another piece of filter cloth over the damaged area. All connecting joints should overlap a minimum of 1 ft. If the damage is extensive, replace the entire filter cloth. 4. Riprap may be placed by equipment, but take care to avoid damaging the filter. 5. The minimum thickness of the riprap should be 1.5 times the maximum stone diameter. 6. Riprap may be field stone or rough quarry stone. It should be hard, angular, highly weather - resistant and well graded. 7. Construct the apron on zero grade with no overfall at the end. Make the top of the riprap at the downstream end level with the receiving are or slightly below it. S. Ensure that the apron is properly aligned with the receiving stream and preferably straight throughout its length. If a curve is needed to fit site conditions, place it in the upper section of the apron. 9. Immediately after construction, stabilize all disturbed areas with vegetation (Practice 6.10, Temporary Seeding, and 6.11, Permanent Seeding). Maintenance Inspect riprap outlet structures after heavy rains to see if any erosion around or below the riprap has taken place or if stones have been dislodged. Immediately make all needed repairs to prevent further damage. Hanove- �esic,n Services 1123 floral PI<wy.

Ensure that road construction follows the natural contours of the tcrrain if it is possible. 3. Locate parking areas on naturally flat areas if they are available. Keep grades sufficient for drainage but generally not more than 2 to 3%. 4. Provide surface drainage, and divert excess runoff to stable areas by using water bars or turnouts (References: Runoff Control Measures). 5. Keep cuts and fills at 2:1 or flatter for safety and stability and to facilitate establishment of vegetation and maintenance. 6. Spread a 6-inch course of "ABC" crushed stone evenly over the full width of the road and smooth to avoid depressions. 7. Where seepage areas or seasonally wet areas must be crossed, install subsurface drains or geotextile fabric cloth before placing the crushed stone (Practice 6.81, Subsurface Drain). 8. Vegetate all roadside ditches, cuts, fills and other disturbed areas or otherwise appropriately stabilize as soon as grading is complete (References: Surface Stabilization). 9. Provide appropriate sediment control measures to prevent off -site sedimentation. Maintenance Inspect construction roads and parking areas periodically for condition of surface. Topdress with new gravel as needed. Check road ditches and other seeded areas for erosion and sedimentation after runoff -producing rains. Maintain all vegetation in a healthy, vigorous condition. Sediment - producing areas should be treated immediately. Hanover Design Services 1123 floral Pkwy. Wilmington, NC 28403 Wilmington, NO 28403 Temporary Seeding Specification # 610 Specifications Complete grading before preparing seedbeds and install all necessary erosion control practices, such as dikes, water ways and basins. Minimize steep slopes because they make seedbed preparation difficult and increase the erosion hazard. If soils become compacted during grading, loosen them to a depth of 6-8 inches using a ripper, harrow, or chisel plow. Seedbed Preparation Good seedbed preparation is essential to successful plant establishment. A good seedbed is well -pulverized, loose and uniform. Where hydroseeding methods are used, the surface may be lift with a more irregular surface of large clods and stones. 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 %: tonstacre on coarse -textured soils and 2-3 tons/acres 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 cuses the surface to become sealed or crusted, loosen it just prior to seeding by disking, raking, harrowing, or other suitable methods, Groove or furrow slopes steeper than 3:1 on the contour before seeding (Practice 6:03, Surface Roughening). Plant Selection Select an appropriate species or species mixture from Table 6 10a, for seeding in late winter and early spring, Table 6.10b for summer, and Table 6.10c for fall.. heir , 6100'?S i V_c r Ir,.:l rimy Wilmington, NC 28403 Seeding Evenly apply seed using a cyclone seeder (broadcast), drill, cultipacker seeder, or hydroseeder. Use seeding rates given in Table 6.10a-6.10c. Broadcast seeding and hyroseeding are appropriate for steep slopes wher equipment cannot be driven. Hand broadcasting is not recommended because of the difficulty in achieving a uniform distribution. Small grains should be planted no more than 1 inch deep, and grasses and legumes no more than inch. Broadcast seed must be covered by raking or chain dragging, and then lightly firmed with a roller or cultipacker. Hydroseeded mixtures should include a wood fiber (cellulose) mulch. Mulching The use of an appropriate mulch will help ensure establishment under normal conditions and is essential to seeding success under harsh site condition (Practice 6 14, Mulching). Harsh site conditions include: -seeding in fall ,for winter cover (wood fiber mulches are not considered adequate for this use), -slopes steeper than 3:1, -excessively hot.or dry weather, -adverse soils(shallow, rocky, or high in clay or sand), and -areas receiving concentrated flow. If the area to be mulched is subject to concentrated waterflow, as in channels, anchor mulch with netting (Practice 6.14, Mulching).

Wilmington, NC 28403 Permanent Seeding Specifications # 6.11 Specifications Seedbed Requirements Establishment of vegetation should not be attempted on sites that are unsuitable due to inappropriate soil texture (Table 6.1la), poor drainage, concentrated overland flow, or steepness of slope until measures have been taken to correct these problems. To maintain a good stand of vegetation, the soil must meet certain minimum requirements as a growth medium. The existing soil should have these criteria: - Enough fine-grained (silt and clay) material to maintain adequate moisture and nutrient supply (available water capacity of at least .05 inches water to I inch of soil). - Sufficient pore space to permit root penetration. - Sufficient depth of soil to provide an adequate root zone. The depth to rock or impermeable layers such as hardpans should be 12 inches or more, except on slopes steeper than 2:1 where the addition of soil is not feasible. - A favorable pH range for plant growth, usually 6.0-6.5. - Freedom from large roots, branches, stones, large clods of earth, or trash of any kind. Clods and stones may be left on slopes steeper than 3:1 if they are to be hydroseeded. If any of the above criteria are not met-i.e., if the existing soil is too coarse, dense, shallow or acidic to foster vegetation=special amendments are required. The soil conditioners described below may be beneficial or, preferably, topsoil may be applied in accordance with Practice 6.04, Topsoiling. Soil Conditioners In order to improve the structure or drainage characteristics of a soil, the following material may be added. These amendments should only be necessary where soils have limitations that make them poor for plant growth or for fine turf establishment (see Chapter 3, Vegetative Considerations). Peat -Appropriate types are sphagnum moss peat, hypnum moss peat, reedsedge peat, or peat humus, all from fresh -water sources. Peat should be shredded and conditioned in storage piles for at least 6 months after excavation. Sand -clean and free of toxic materials Vermiculite -horticultural grade and free of toxic substances. Rotted manure -stable or cattle manure not containing undue amounts of straw or other bedding materials. Thoroughly rotted sawdust- free of stones and debris. Add 6 lb. Of nitrogen to each cubic yard Sludge -Treated sewage and industrial sludges are available in various forms: these should be used only in accordance with local, State and Federal regulations. Hanover Design Services 1 123 Floral Pkwy. Wilmington, NC 20403 Species Selection Use the key to Permanent Seeding Mixtures (Table 6.1lb) to select the most appropriate seeding mixture based on the general site and maintenance factors. A listing of species, including scientific names and characteristics, is given in Appendix 8.02. Seedbed Preparation Install necessary mechanical erosion and sedimentation control practice.; before seeding, and complete grading according to the approved plan. Lime and fertilizer needs should be determined by soil tests. Soil testing is performed free of charge by the North Carolina Department of Agriculture soil testing laboratory. Directions, sample cartons, and information sheets are available through county. Agricultural extension offices or from NCDA . Because the NCDA soil testing lab requires 1-6 weeks for sample turn- around, sampling must be planned well in advance of final grading. Testing is also done by commercial laboratories. When soil test are not available, follow rates suggested on the individual specification sheet for the seeding mix chosen (Tables 6.11c through 6.11v). Applications rates usually fall into the following ranges: - Ground agricultural limestone Light -textured, sandy soils; 1-1 %z tons/acre Heavy textured, clayey soils 2-3 tons/acre - Fertilizer: Grasses 800-1200 lb/acre of 10-10-10 (or the equivalent) Grass -legume mixtures: 800-12001b/acre of5-10-10 (or the equivalent) Apple lime and fertilizer evenly and incorporate into the top 4-6 inches of soil by disking or other suitable means. Operate machinery on the contour. When using a hydroseeder, apply lime and fertilizer to a rough, loose surface. Roughen surfaces according to Practice 6.03, Surface Roughening. Complete seedbed preparation by breaking up large clods and raking into a smooth, uniform surface (slope less than 3:1) Fill in or level depressions than can collect water.

Wilmingioi i, NC 28403 Sediment Basin Specifications # 6 61 Construction Specifications Site preparations —Clear, grub and strip topsoil from areas under the embankment to remove trees, vegetation, roots and other objectionable material. Delay clearing the pool area until the dam is complete and then remove brushy trees and uthei objectionable materials to facilitate sediment cleanout. Stockpile all topsoil or soil containing organic matter for use on the outer shell of the embankment to facilitate vegetative establishment. Place temporary sediment control measures below the basin as needed. 2. Cut-off trench —Excavate a cut-off trench along the centerline of the earth fill embankment. Cut the trench to stable soil material, but in no case make it less than 2 ft. deep. The cut-off trench must extend into both abutments to at least the elevation of the riser crest. Make the minimum bottom width wide enough to permit operation of excavation and compaction equipment but in no case less than 2 ft. Make side slopes of the trench no steeper than 1:1. Compaction requirements are the same as those for the embankment. Keep the trench dry during backfilling and compaction operations. Embankment —Take fill material from the approved areas shown on the plans. It should be clean mineral soil, free of roots, woody vegetation, rocks and other objectionable material. Scarify areas on which fill is be placed before placing fill. The fill material must contain sufficient moisture so it can be formed by hand into a ball without crumbling. If water can be squeezed out of the ball, it is too wet for proper compaction. Place fill material in 6 to 8-inch continuous layers over the entire length of the fill area and then compact it. Compaction may be obtained by routing the construction hauling equipment over the fill so that the entire surface of each layer is traversed by at least one wheel or tread track of the heavy equipment, or a compactor may be used. Construct the embankment to an elevation 10% higher than the design height to allow for settling. 4. Conduit spillways —Securely attach the riser to the barrel or barrel stub to make a watertight structural connection. Secure all connections between barrel sections by approved watertight assemblies. Place the barrel and riser on a firm, smooth foundation of impervious soil. Do not use pervious material such as sand, gravel, or crushed stone as backfill around the pipe or anti -seep collars. Place the fill material around the pipe spillway in 4-inch layers and compact it under and around the pipe to at least the same density as the adjacent embankment. Care must be taken no to raise the pipe from firm contact with its foundation when compacting under the pipe haunches. Place a minimum depth of 2ft. of hand -compacted backfill over the pipe spillway before crossing it with construction equipment. Anchor the riser in place by concrete or other satisfactory means to prevent flotation. In no case should the pipe conduit be installed by cutting a trench through the dam after the embankment is complete. Emergency spillway —Install the emergency spillway in undisturbed soil. The achievement of planned elevations, grade, design width, and entrance and exit channel slopes are critical to the successful operation of emergency spillway. Hanover Design Services 1123 Pl,jral Pkvvy. Wilmingtr.•n. NC 28-403 6. Inlets —Discharge water into the basin in a manner to prevent erosion. Use diversions with outlet protection to divert sediment -laden water to the upper end of the pool area to improve basin trap efficiency (References: Runoff Control Measures and Outlet Protection). 7. Erosion control —Construct the structure so that the disturbed area is minimized. Divert surface water away from bare areas. Complete the embankment before the area is cleared. Stabilize the emergency spillway embankment and all other disturbed areas above the crest of the principal spillway immediately after construction (References: Surface Stabilization). 8. Safety —Sediment basins may attract children and can be dangerous. Avoid steep side slopes, and fence and mark basins with warning signs if trespassing is likely. Follow all state and local requirements. Maintenance Check sediment basins afier periods of significant runoff. Remove sediment and restore the basin to its original dimensions when sediment accumulates to one-half the design depth. Check the embankment, spillways, and outlet for erosion damage, and inspect the embankment for piping and settlement. Make all necessary repairs immediately. Remove all trash and other debris from the riser and pool area. Hanover Design Services 1123 Floi al Pkwy. Wilmington, NC 28403 Pender Progress Impervious Totals HANOVER DESIGN SERVICES, P.A.

Observations: One soil boring and an existing receiving non -jurisdictional ditch were observed as follows (location map attached): The seasonal high water table is normally evident by observation of redoximorphic features suggesting past conditions of saturation and reduction, indicated by colors of chroma 2 or less (Munsell) at greater than 2% of soil volume in mottles or a distinct horizon subdivision. There was evidence of redoximorphic features at about 6"-7" (0.6') in the bore with a distinct gray chroma (the first 1" at the test site was vegetable matter, not soil). This observation was in line with the expected depth to seasonal high water in the published soil profile of 0'-1'. Elevation read at the boring for Pond 1 was 52.02 MSL, resulting in a SHWT elevation of 51.4 MSL (52.0 — 0.6 = 51.4). Additionally, an existing non -jurisdictional receiving ditch was observed in the vicinity of the Pond 1 outfall and the boring, which indicated standing water at elevation 51.38 MSL and no distinct horizon of chroma change above that elevation. Summary: Observed indications of SHWT depth were in line with predicted values. Pond No.1 SHWT = 51.4 MSL. 0� .... Ilk SS13 9 SEAL 20007 12207-SHWT doc ,"�S� ,N�.°`- David S.

TYPE LOCATION: Edgecombe County, North Carolina; 1.5 miles west of Pinetops on SR 1124 and 800 feet north of road. RANGE IN CHARACTERISTICS: Solum thickness is more than 60 inches. The soil is strongly acid through extremely acid, except where the surface and upper subsoil have been limed. The A or Ap horizon has hue of 10YR or 2.5Y, value of 2 to 5, and chroma of 1 or 2. Texture is very fine sandy loam, loam, or silt loam. The Eg horizon has hue of 10YR or 2.5Y, value of 5 to 7, and chroma of 1 or 2. Texture is very fine sandy loam, loam, or silt loam. The BEg horizon has hue of 1 OYR or 2.5Y, value of 5 to 7, and chroma of 1 or 2. Most pedons have masses of iron accumulation in shades of brown, yellow, or red. Texture is loam or silt loam. The Btg horizon has hue of 10YR or 2.5Y, value of 5 to 7, and chroma of 1 or 2. There are few to many masses of iron accumulation in shades of red, yellow, or brown. Texture is loam, clay loam, or silty clay loam. The upper 20 inches of this horizon contains more than 30 percent silt, and the sand fraction is dominantly very fine. The BCg or CBg horizon, where present, has hue of 10YR to 5Y, value of 5 to 7, and chroma of 1 or 2. Masses of iron accumulation in shades of yellow, red, or brown are few to many. Texture is loam, clay loam, or silty clay loam. The Cg horizon, where present, has hue of 10YR or 2.5Y, value of 5 to 7, and chroma of 1 or 2. Masses of iron accumulation in shades of red, yellow, or brown are few to many. Texture is variable, consisting of stratified layers of sandy, loamy, or clayey material of varying thickness. COMPETING SERIES: The Trebloc series is in the same family and the Bethera, Coxville, Leaf, Liddell, Myatt, Pasquotank, Rains, and Woodington series are in closely -related families. Trebloc soils are on terraces, and in depressions and drainageways on uplands, typically have higher silt content in the upper 20 inches of the argillic horizon, and have lower average yields. (See 'Remarks"). Bethera, Coxville and Leaf soils have more than 35 percent clay in the control section. Liddell, Pasquotank, and Woodington soils have less than 18 percent clay in the control section. Myatt soils have more than 15 percent fine or coarser sand in the upper 20 inches of the argillic horizon and also have sandy 2C horizons at depths of less than 60 inches. Rains soils have less than 30 percent silt, and fine or coarser sand dominates the sand fraction of the upper 20 inches of the argillic horizon. GEOGRAPHIC SETTING: Grantham soils are nearly level and are on uplands in the Middle and Hanover Design Services 1123 Floral Pkvvy.

The soils formed in loamy and silty Coastal Plain sediments. The climate is warm and humid. Mean annual air temperature near the type location is 61 degrees F., and mean annual precipitation is about 47 inches. GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the competing Liddell and Rains series, these include the Aycock, Exum, Foreston, Goldsboro, Nahunta, and Stallings series. Aycock soils are well drained and Exum, Foreston, and Goldsboro soils are moderately well drained. Stallings and Nahunta soils are somewhat poorly drained. In addition, Goldsboro, Foreston, and Stallings soils have less than 30 percent silt in the argillic horizon. All the associated soils except Rains are in higher positions or are nearer to drainageways. DRAINAGE AND PERMEABILITY: Poorly drained; slow to very slow runoff; moderately slow permeability. USE AND VEGETATION: About two-thirds of the acreage is forested. Common trees include loblolly pine, pond pine, sweetgum, water oak, red maple, yellow poplar, blackgum, and willow oak. Understory plants include greenbrier, giant cane, sweetbay, switchcane, blueberry, fetterbush lyonia, summersweet clethra, redbay, inkberry, southern bayberry, and American holly. About one-third of the acreage has been cleared, drained, and is used primarily for growing corn, soybeans, small grains, and pasture. DISTRIBUTION AND EXTENT: North Carolina and possibly South Carolina and Virginia. The series is of moderate extent. MLRA OFFICE RESPONSIBLE: Raleigh, North Carolina SERIES ESTABLISHED: Edgecombe County, North Carolina; 1976. REMARKS: The soils now placed in the Grantham series were formerly included with the Myatt and Trebloc series. The differences between Grantham and Trebloc soils need further study. Trebloc soils are presumed to have mineralogical or chemical differences based on landform and higher silt content. Diagnostic horizons and soil characteristics recognized in this pedon are: Ochric epipedon - the zone from the surface to a depth of 11 inches (the A and Eg horizons) Albic horizon - the zone from a depth of 6 to 11 inches (the Eg horizon) Argillic horizon - the zone from a depth of 13 to 77 inches (the Big I, Btg2, and Btg3 horizons) Aguic conditions - redoxymorphic features throughout the soil MLRA(S): 133A, 153A SIR: NCO100 TABULAR SERIES DATA: SOI-5 Soil Name Slope Airtemp FrFr/Seas Precip Elevation NCO100 GRANTHAM 0- 2 58- 63 185-240 45- 55 40- 170 SOI-5 F1oodL F1oodH Watertable Kind Months Bedrock Hardness NC0100 NONE 0-1.0 APPARENT DEC -MAY 60-60 SOI-5 Depth Texture 3-Inch No-10 Clay% -CEC- NC0100 0-11 VFSL L SIL 0- 0 100-100 6-18 3- 8 NC0100 11-77 L CL SICL 0- 0 100-100 18-35 4- 8 NCO100 77-99 VAR - - - - SOI-5 Depth -pH- O.M.
