Any needed repairs will be made immediately to maintain all practices as designed. 2. Sediment will be removed from behind the silt fence when it becomes 0.5 feet deep. 3. Sediment will be removed from the sediment trap when the storage has been approximately 50% filled. Gravel will be cleaned and replaced when the sediment pool no longer drains properly. 4. All seeded areas will be fertilized, re -seeded as necessary, and mulched according to specifications in the vegetative plan to maintain a vigorous, dense vegetative cover. Vill. VICINITY PLAN See Erosion Control Plan IX. VEGETATION PLAN See Construction Drawings X. A. 6.02 Land Grading 1. Construct and maintain all erosion and sedimentation control practices and measures in accordance with the approved sedimentation control plan and construction schedule. 2. 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 by removing 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, 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. B. 6.06 Temporary Gravel Construction Entrance 1. Clear the entrance and exit area of all vegetation, roots, and other objectionable material and properly grade it. 2. Place the gravel to the specific grade and dimensions shown on the plans, and smooth it. 3. Provide drainage to carry water to a sediment trap or other suitable outlet. 4. Use geotextile fabrics because they improve stability of the foundation in locations subject to seepage or high water table. C. 6.14 Mulching Select a material based on site and practice requirements, availability of material, labor, and equipment. Table 6.14a lists commonly used mulches and some alternatives. Before mulching, complete the required grading, install sediment control practices, and prepare the seedbed. Apply seed before mulching except in the following cases: • Seed is applied as part of a hydroseeder slurry containing wood fiber mulch. • A hydroseeder slurry is applied over straw APPLICATION OF ORGANIC MULCH Organic mulches are effective where they can be lacked securely to the surface Material and specifications are given in Table 6.14a. Spread mulch uniformly by hand, or with a mulch blower. When spreading straw mulch by hand, divide the area to be mulched into sections of approximately 1,000 ft2, and place 70-90 lb of straw ( 1 1/2 to 2 bales) in each section to facilitate uniform distribution. After spreading mulch, no more than 25% of the ground surface should be visible. In hydroseeding operations a green dye, added to the slurry, assures a uniform application. ANCHORING ORGANIC MULCH Straw mulch must be anchored immediately after spreading. The following methods of anchoring mulch may be used: Mulch anchoring tool —A tractor -drawn implement designed to punch mulch into the soil, a mulch anchoring tool provides maximum erosion control with straw. A regular farm disk, weighted and set nearly straight, may substitute, but will not do a job comparable to the mulch anchoring tool. The disk should not be sharp enough to cut the straw. These methods are limited to slopes no steeper than 3:1, where equipment can operate safely. Operate machinery on the contour. Liquid mulch binders —Application of liquid mulch binders and tackffiers should be heaviest at the edges of areas and at crests of ridges and banks, to resist wind. Binder should be applied uniformly to the rest of the area. Binders may be applied after mulch is spread, or may be sprayed into the mulch as it is being blown onto the soil. Applying straw and binder together is the most effective method. Liquid binders include asphalt and an array of commercially available synthetic binders. Emulsified asphalt is the most commonly used mulch binder. Any type thin enough to be blown from spray equipment is satisfactory. Asphalt is classified according to the time it takes to cure. Rapid setting IRS or CRS designation) is formulated for curing in less than 24 hours, even during periods of high humidity; it is best used in spring and fall. Medium setting (MS or CMS) is formulated for curing within 24 to 48 hours, and slow setting (SS or CSS) is formulated for use during hot, dry weather, requiring 48 hours or more curing time. Apply asphalt at 0.10 gallons per square yard (10 gal/1,000 ft2). Heavier applications cause straw to "perch" over rills. In traffic areas, uncured asphalt can be picked up on shoes and cause damage to rugs, clothing etc. Use types RS or CRS to minimize such problems. Synthetic binders such as Petroset, Terrateck, and Aerospray may be used, as recommended by the manufacturer, to anchor mulch. These are expensive, and therefore usually used in small areas or in residential areas where asphalt may be a problem (Use of trade names does not constitute an endorsement). Mulch neftings—Lightweight plastic, cotton, jute, wire, or paper nets may be stapled over the mulch according to the manufacturer's recommendations (see "Nets and Mats" below). Peg and twine —Because it is labor-intensive, this method is feasible only in small areas where other methods cannot be used. Drive 8-10 inch wooden pegs to within 3 inches of the soil surface, every 4 feet in all directions. Stakes may be driven before or after straw is spread. Secure mulch by stretching twine between pegs in a criss-cross-within-a-square pattern. Turn twine two or more times around each peg. Twine may be tightened over the mulch by driving pegs further into the ground. Vegetation —Rye (grain) may be used to anchor mulch in fall plantings, and German millet in spring. Broadcast at 15 lb/acre before applying mulch. CHEMICAL MULCHES Chemical mulches may be effective for soil stabilization if used between May 1 and June 15, or Sept. 15 and Oct. 15, provided that they are used on slopes no steeper than 4:1, and that proper seedbed preparation has been accomplished, including surface roughening where required. Chemical mulches may be used to bind other mulches, or with wood fiber in a hydroseeded slurry at any time. Follow the manufacturer's recommendations for application. .Y[7X:CH�SY93i19G[e' Fiberglass roving ('roving") is wound into a cylindrical package so that It can be continuously withdrawn from the center using a compressed air ejector. Roving expands into a mat of glass fibers as it contacts the soil surface. It is often used over a straw mulch, but must still be lacked with asphalt. Spread roving uniformly over the area at a rate of 0.25 to 0.35 Ib/yd2. Anchor with asphalt immediately after application, at a rate of 0.25 to 0.35 gal/yd2. As a channel lining, and at other sites of concentrated flow, the roving mat must be further anchored to prevent undermining. It may be secured with stakes placed at intervals no greater than 10 feet along the drainageway, and randomly throughout its width, but not more than 10 feet apart. As an option to staking, the roving can be buried to a depth of 5 inches at the upgrade end and at intervals of 50 feet along the length of the channel. NETS AND MATS Nets alone generally provide little moisture conservation benefits and only limited erosion protection. Therefore, they are usually used in conjunction with an organic mulch such as straw. Except when wood fiber slurry is used, netting should always be installed over the mulch. Wood fiber may be sprayed on top of an installed net. Mats, including "excelsior" (wood fiber) blankets, are considered protective mulches and may be used alone, on erodible soils, and during all times of the year. Place the matting in firm contact with the soil, and staple securely. INSTALLATION OF NETTING AND MATTING Products designed to control erosion should be installed in accordance with manufacturer's instructions. Any mat or blanket -type product used as a . protective mulch should provide cover of at least 30% of the surface where it is applied. Installation is illustrated in Figure 6.14a. 1. Apply lime, fertilizer, and seed before laying the net or mat. 2. Start laying the net from the top of the channel or slope, and unroll it down the grade. Allow netting to lay loosely on the soil or mulch cover but without wrinkles —do not stretch. 3. To secure the net, bury the upslope end in a slot or trench no less than 6 inches deep, cover with soil, and tamp firmly as shown in Figure 6.14a. Staple the net every 12 inches across the top end and every 3 ft around the edges and bottom. Where 2 strips of net are laid side by side, the adjacent edges should be overlapped 3 inches and stapled together. Each strip of netting should also be stapled down the center, every 3 ft. Do not stretch the net when applying staples. 4. To join two strips, cut a trench to anchor the end of the new net. Overlap the end of the previous roll 18 inches, as shown in Figure 6.14a, and staple every 12 inches just below the anchor slot. D. 6.51 Fabric Drop Inlet Protection (Temporary) 1. Uniformly grade a shallow depression approaching the inlet 2. Drive 5-foot steel posts 2 feet into the ground surrounding the inlet. Space posts evenly around the perimeter of the inlet, a maximum of 4 feet apart. 3. Surround the posts with wire mesh hardware cloth. Secure the wire mesh to the steel posts at the top, middle, and bottom. Placing a 2-foot flap of the wire mesh under the gravel for anchoring is recommended. 4. Place clean gravel (NC DOT #5 or #57 stone) on a 2:1 slope with a height of 16 inches around the wire, and smooth to an even grade. 5. Once the contributing drainage area has been stabilized, remove accumulated sediment, and establish final grading elevations. 6. Compact the area properly and stabilized it with groundcover E. 6.60 Temporary Sediment Trap 1. Clear, grub, and strip the area under the embankment of all vegetation and root mat. Remove all surface soil containing high amounts of organic matter, and stockpile or dispose of it properly. Haul all objectionable material to the designated disposal area. 2. Ensure that fill material for the embankment is free of roots, woody vegetation, organic matter, and other objectionable material. Place the fill in lifts not to exceed 9 inches, and machine compact it. Over fill the embankment 6 inches to allow for settlement. 3. Construct the outlet section in the embankment. Protect the connection between the riprap and the soil from piping by using filter fabric or a keyway cutoff trench between the riprap structure and soil. • Place the filter fabric between the riprap and the soil. Extend the fabric across the spillway foundation and sides to the top of the dam; or • Excavate a keyway trench along the center line of the spillway foundation extending up the sides to the height of the dam. The trench should be at least 2 feet deep and 2 feet wide with 1:1 side slopes. 4. Clear the pond area below the elevation of the crest of the spillway to facilitate sediment cleanout. 5. All cut and fill slopes should be 2:1 or flatter 6. Ensure that the stone (drainage) section of the embankment has a minimum bottom width of 3 feet and maximum side slopes of 1:1 that extend to the bottom of the spillway section. 7. Construct the minimum finished stone spillway bottom width, as shown on the plans, with 2:1 side slopes extending to the top of the over filled embankment. Keep the thickness of the sides of the spillway outlet structure at a minimum of 21 inches. The weir must be level and constructed to grade to assure design capacity. 8. Material used in the stone section should be a well -graded mixture of stone with a d50 size of 9 inches (class 8 erosion control stone is recommended) and a maximum stone size of 14 inches. The stone may be machine placed and the smaller stones worked into the voids of the larger stones. The stone should be hard, angular, and highly weather -resistant. 9. Discharge inlet water into the basin in a manner to prevent erosion. Use temporary slope drains or 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), 10. Ensure that the stone spillway outlet section extends downstream past the toe of the embankment until stable conditions are reached and outlet velocity is acceptable for the receiving stream. Keep the edges of the stone outlet section flush with the surrounding ground, and shape the center to confine the outflow stream (References: Outlet Protection), 11. Direct emergency bypass to natural, stable areas. Locate bypass outlets so that flow will not damage the embankment. 12. Stabilize the embankment and all disturbed areas above the sediment pool and downstream from the trap immediately after construction (References: Surface Stabilization). 13. Show the distance from the top of the spillway to the sediment cleanout level (1/2 the design depth) on the plans and mark it in the field. 14. Install porous baffles as specified in Practice 6.65, Porous Baffles. F. 6.62 Temporary Sediment Fence MATERIALS 1. Use a synthetic filter fabric of at least 95% by weight of polyolefins or polyester, which is certified by the manufacturer or supplier as conforming to the requirements in ASTM D 6461, which is shown in part in Table 6.62b. Synthetic filter fabric should contain ultraviolet ray inhibitors and stabilizers to provide a minimum of 6 months of expected usable construction life at a temperature range of 0 to 1200 F. 2. Ensure that posts for sediment fences are 1.33 lb/linear ft steel with a minimum length of 5 feet. Make sure that steel posts have projections to facilitate fastening the fabric. 3. For reinforcement of standard strength filter fabric, use wire fence with a minimum 14 gauge and a maximum mesh spacing of 6 inches.

JANOWSKI ENGINEERING, PA GENERAL PROJECT INFORMATION This project includes the construction of a new building addition, parking lots, storm drainage and a storm water wet detention pond. Approximately 24,448 SF of new buildings will be constructed. The parking lot ✓ and access improvements will account—fo>r 56,343 SF of new pavement and walks. The property is ✓ bounded on the north by Evans -Bass Road (SR 1216), on the south and west by undeveloped property, and on the east by Rocky Hock Church Road. The site has slopes averaging 0 to 1.5%. Overall, elevations vary from a high point of 23 feet above sea level to a low point of 15.0 feet above sea level. The soil types on the site are Conetoe Loamy Sands and Lynchburg soils. This project drains to Rocky Hock Creek in the Chowan River Basin. STORMWATER INFORMATION _ -17g'�t_ o �rG` Pre -development, this project site consists of 5.77 acres of property and 1.19 acres of offsite property totaling 6.96 acres and includes the wet detention site. The existing slopes are averaging from 0% to 1.5% and 88,445 sf of existing -impervious -building, -pavement -and walks. Existing surface drainage is currently draini g ards the west property line where an existing ditch exists. The proposed development will add 80,791 sf of new and 43,561 sf future impervious -area. — Post -development, runoff from 6.96 acres will be collected in a proposed storm drainage system consisting reinforced concrete pipe before it is discharged into the proposed wet detention pond. From the detention pond, the outflow will be discharged into an existing ditch that drains westward and then southward towards Rocky Hock Creek. The total impervious area that will be draining into the new wet detention facility will be 192,797 sf and will include the existing impervious area and the future. 1/ ✓ The purpose of the wet detention pond is to remove 90% total suspended solids in the system, and for the attenuation of the peak stormwater flow of the 1-year, 24-hour storm (80%-2yr). Using the Surface Area to Drainage Area Table for 90% TSS in the Coastal Region, the required surface area for this pond for the inclusion of future development is 11,975 sf. The proposed pond contains 19,414 sf of surface area. The breakdown of the impervious areas for this project site area is as follows: PROJECT SITE AREA BREAKDOWN Total Project Area Post -Development New Building Area Future Building Existing Building Area New Employee Parking New Future Parking Existing Parking Existing walks New walks Total Impervious Area Post -Development Percent Impervious 6.96 ac 24,448 sf 20,000 sf 20,880 sf 52,143 sf 23,561 sf 43,311 sf 4,254 sf 4200 sf 192,797 sf or 4.426 ac 63.59 % for the BMP .

Dear Mr. Janowski, As requested, a seasonal high water table determination was conducted on June 15, 2013 for Rocky Hock Baptist Church in Chowan County, NC. The method of soil evaluation utilized one hand auger boring to a depth of 25 inches. The boring location was based on a plan provided by you. An enclosed map identifies the approximate location of the boring conducted. The findings of this investigation suggest a seasonal high water table is approximately 12 inches from the surface. The method of determination was based on the presence of soil morphological features containing 2% chroma 2 color or less mottles within the subsoil. The soil profile description contained: 1. Ap - 0-8inches; black (10YR 2/1) sandy loam; granular structure; friable. Big — 8-25 inches; dark grayish brown (10YRY4/2) sandy clay loam; weak fine subangular blocky structure; friable.
