Subject: Request for Additional Information Stormwater Project No. SW8 010515 Waves Beachwear Pender County Dear Mr. Shitrit: The Wilmington Regional Office received previously requested information regarding the Stormwater Management Permit Application for Waves Beachwear on June 19, 2003. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Please provide the street address of the project in Section 5 of the application. 2. Please report the built -upon area in square feet on the application. This information was available in the calculations, so I have transferred it to the application for you. 3. The location of the outlet structure is not usually in the middle of the pond, where it will be difficult to access for routine maintenance. Please relocate it close to the slope, where it can be accessed more easily. You will be required to provide a safe bridged access to the outlet structure if you want to leave it in the middle of the pond. 4. Please add the pond seeding specifications to the plans. N. C.

Please provide finished grade elevations and spot elevations to demonstrate that all the runoff will be directed into the inlet swale along the southern property line, and will not simply flow onto the adjacent property, or into the road ditch. 6. Please provide dimensions for the front parking lot, sidewalk and rear gravel area. 7. Please be more specific in describing the trash rack, and specify a maximum spacing of 4" x 4" for trash rack openings. 8. Please check the orifice calculation. It appears that the consultant forgot to multiply by "rr" when calculating the orifice area in square feet. The 1.25" specified is too large. Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to close of business on June 25, 2003, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. . If you need additional time to submit the information, please mail or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the required information. The Division is allowed 90 days from .the receipt of a completed application to issue the permit. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143- 215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.

Sullins, Deputy Director Division of Water Quality June 20, 2003 Henry Shitrit, President H & D Properties, LLC 14418 Ocean Highway Pawley's Island, SC 29585 Subject: Request for Additional Information Stormwater Project No. SW8 010515 Waves Beachwear Pender County Dear Mr. Shitrit: The Wilmington Regional Office received previously requested information regarding the Stormwater Management Permit Application for Waves Beachwear on June 19, 2003. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Please provide the street address of the project in Section 5 of the application. 2. Please report the built -upon area in square feet on the application. This information was available in the calculations, so I have transferred it to the application for you. 3. The location of the outlet structure is not usually in the middle of the pond, where it will be difficult to access for routine maintenance. Please relocate it close to the slope, where it can be accessed more easily. You will be required to provide a safe bridged access to the outlet structure if you want to leave it in the middle of the pond. 4. Please add the pond seeding specifications to the plans. 5. Please provide finished grade elevations and spot elevations to demonstrate that all the runoff will be directed into the inlet swale along the southern property line, and will not simply flow onto the adjacent property, or into the road ditch. 6. Please provide dimensions for the front parking lot, sidewalk and rear gravel area. 7. Please be more specific in describing the trash rack, and specify a maximum spacing of 4" x 4" for trash rack openings. N. C.

Y � SEEDING SCHEDULE WAVES APPAREL SURF CITY PENDER COUNTY, NORTH CAROLINA June 18, 2003 1.0 PLANTING SPECIFICATIONS Seeding, mulching, and conditioning of the soils on the subject site is to be performed to North Carolina Department of Transportation requirements, Section 880, Standard Specifications for Roads & Structures, with the following provisions: 1.1 Seeding, mulching, and conditioning shall be done on all earth areas disturbed or filled by channel dredging, construction or as designated by the Engineer. 1.2 Seeding, mulching, and conditioning shall be accomplished as soon as possible after land disturbance to stabilize the soils and prevent erosion. The soils shall be stabilized permanently between the months of April and June. The time for establishment of a permanent ground cover is 15 days or 90 calendar days, which ever is shorter. Prior to permanent seeding, the soils shall be seeded, mulched, and conditioned for a temporary grass cover as herein specified, 1.3 In order to prevent excessive soil erosion and siltation, a grass cover shall be established as soon as possible following land disturbing and construction operations. The Contractor shall complete grading to the proper final grade and then perform seeding, mulching, and conditioning as the final grading progresses or within 30 calendar days thereof, unless there is a specific permissible length of delay due to circumstances beyond the control of the Contractor. 1.4 Superficial scratching of the slope surface will not be sufficient seedbed preparation. On 2:1 or 12:1 slopes, a seedbed preparation will be required approaching the degree of preparation required on flatter areas as far as depth is concerned although the same degree of smoothness of seedbed will not be required. 1.5 The kind of seed, the rate of application of seed, limestone, and fertilizer is as follows (Contractor will be responsible for performing tests of on -site soils): Temporary Seeding - Fall Seeding Mixture Species: Rye (grain) Rate (lb/acre): 120 Seeding Dates: August 15 - December 30 Soil Amendments: Follow recommendations of soil tests from the Agriculture Extension Service for fertilizer and time application rates. Mulch: Apply 4,000 lb/acre straw. Anchor straw by tacking with asphalt, netting, or a mulch anchoring tool. A disk with blades set nearly straight can be used as a mulch anchoring tool. Maintenance: Repair and re -fertilize damaged areas immediately. Top dress with 50 lb/acre of nitrogen in March. If it is necessary to extend temporary cover beyond June 15, over seed with 50 lb/acre Kobe. Temporary Seeding - Late Winter and Early Spun Seeding Mixture Species: Rye (grain) Rate (lb/acre): 120 Annual Iespedeza Rate (lb/acre): 50 (Kobe) Omit annual Iespedeza when duration of temporary cover is not to extend beyond June. Seeding Dates: December 1 - April 15 Soil Amendments: Follow recommendations of soil tests from the Agriculture Extension Service for fertilizer and lime application rates. Mulch: Apply 4,000 lb/acre straw. Anchor straw by tacking with asphalt, netting, or a mulch anchoring tool. A disk with blades set nearly straight can be used as a mulch anchoring tool. Maintenance: Re -fertilize if growth is not fully adequate. Re -seed, re -fertilize and mulch immediately following erosion or other damage. Temporary Seeding- Summer Seeding Mixture Species: German millet Rate (lb/acre): 40 Seeding Dates: April 15 - August 15 Soil Amendments: Follow recommendations of soil tests from the Agriculture Extension Service for fertilizer and lime application rates. Mulch: Apply 4,000 lb/acre straw. Anchor straw by tacking with asphalt, netting, or a mulch anchoring tool. A disk with blades set nearly straight can be used as a mulch anchoring tool. Maintenance: Re -fertilize if growth is not fully adequate. Re -seed, re -fertilize and mulch immediately following erosion or other damage. Permanent Seeding Seeding Mixture Species: Pensacola Bahiagrass Rate (lb/acre): 50 Sericea lespedeza 30 Centipedegrass 5 German millet 10 Seeding Dates: April 1 - July 15 Soil Amendments: Apply lime and fertilizer according to soil tests from the Agriculture Extension Service Mulch: Apply 4,000 lb/acre grain straw or equivalent cover of another suitable mulch. Anchor by tacking with asphalt, roving or netting or by crimping with a mulch anchoring tool. A disk with blades set nearly straight can be used as a mulch anchoring tool. Maintenance: Re -fertilize the following April with 50 lb/acre nitrogen. Repeat as growth requires. May be mowed only once a year. Where a neat appearance is desired, omit sericea and mow as often as needed. Limestone shall contain not less than 85 percent of calcium and magnesium carbonates and shall conform to the following minimum standards: one hundred percent (100%) must pass through U.S. Standard 10 mesh screen and forty percent (40%) must pass through U.S. Standard 100 mesh screen. 1.6 Equipment to be used for the application, covering, and compaction of limestone, fertilizer, and seed shall be approved for that use. Application of seed and fertilizer in water suspension or by air blast methods will not be permitted on slopes flatter than 2:1. Should a hydraulic seeder be used for application of seed and fertilizer, the seed shall not remain in water containing fertilizer for more than 30 minutes prior to application. 1.7 Mulching - Mulch shall be spread uniformly over the area by hand or by means of appropriate mechanical spreaders or blowers to obtain an application satisfactory to the Engineer. It is the intent of this specification that satisfactory applications shall allow some sunlight to penetrate and air to circulate, but also partially shade the ground, reduce erosion, and conserve soil moisture. Care shall be exercised to prevent displacement of soil or seed or other damage to the seeded area during mulching. 1.8 The Contractor shall be required to take sufficient precautions to prevent mulch entering catch basins or pipe lines through displacement by wind, water or other causes. The Contractor shall apply a sufficient amount of asphalt to insure that the mulch is properly held in place. z 1.9 In the application of fertilizer in seeding operations, or in the application of asphalt materials during mulching operations, adequate precautions shall be taken to prevent damage to concrete or metal structures. Such structures shall be adequately covered or application methods changed so as to avoid damage. Where any damage occurs as a result of the Contractor's failure to take adequate precautions, the Contractor will be required to repair such damage including any cleaning that may be necessary before final acceptance of the work. 1.14 Once an area has been seeded and mulched, the Contractor is required to take adequate precautions to insure that all future construction operations do not damage these areas. No payment will be made for repairs of any kind that are due to negligence of the Contractor. 1.11 Fertilizer shall be the standard commercial product of analysis. All fertilizer shall be delivered in bags bearing the manufacturer's name, the chemical analysis of the project, and its weight. If not used immediately after delivery, fertilizer shall be stored in a manner that will not allow it to harden or destroy its effectiveness. 1.12 Seed shall be certified seed or equivalent based on North Carolina Seed Improvement Association requirements for certification. If the seed is not grown in the state where it is to be used, it shall meet the certification requirements of the Seed Improvement Association for the state in which it is grown. All seed shall be furnished in sealed standard containers. Seed which has become wet, moldy, or otherwise damage prior to seeding, will not be acceptable. 1.13 Mulch shall be any of the materials noted below: A) Grain straw or dry hay: Mulch materials which contain an excessive quantity of mature seed of noxious weed or other species which would hinder the establishment of desirable vegetation will not be acceptable. Any mulch material which is in an advanced stage of decomposition as to smother or retard growth of grass will not be acceptable. B) Asphaltic adhesive: Asphaltic material to anchor straw mulch shall be thin enough to be blown from spray equipment. It shall be SS-1 emulsion or RS liquid asphalt I or 2. 1.14 Seed: Furnish duplicate signed copies of a statement from vendor certifying that each container of seed is fully labeled in accordance with the Seed Improvement Association requirements for certification. This certification shall appear on, or with, all copies of invoices for the seed. Each lot of seed will be subject to sampling and testing at the discretion of the Engineer. Sampling and testing will be in accordance with the latest regulation under the Federal Seed Act. 1.15 Fertilizer and Lime: Furnish duplicate copies of invoices for all fertilizer and lime used on the project. Invoices for fertilizer shall show the analysis and the quantity furnished. Invoices for lime shall show the percentage of magnesium oxide and quantity furnished. Upon completion of the project, a final check of the total quantities of fertilizer and lime used will be made against the total area seeded and if the rates of application have not been met, additional quantities of these materials shall be applied to make up the application specified. 1.16 Prior to or during grading and tillage operations, the ground surface shall be cleared of stumps, stones, roots, cable, wire, grade stakes, and other materials that might hinder proper grading, tillage, seeding, or subsequent maintenance operations. 1.17 Grades on the area to be treated shall be maintained in a true and even condition. Maintenance shall include any necessary repairs to previously graded areas. 1.18 All graded areas shall be thoroughly tilled to a depth of at least four inches by plowing, disking, harrowing, or other approved methods until the condition of the soil is acceptable. On sites where soil conditions are such that high clay content and excessive compaction cause difficulty in getting clods and lumps effectively pulverized, the Contractor shall use rotary tillage machinery, until the mixing of the soil is acceptable and no clods or clumps remain larger than 1-1/2 inches in diameter. A firm and compact seedbed is required, and after being graded, the seedbed shall be lightly compacted with a land roller such as a cultipacker, before and after seeding. All tillage operations shall be as near on the contour as is practical, but in not instance up and down the slope. 1.19 Limestone may be applied to the area prior to the preparation of the seedbed, but in all cases, it shall be applied before seeding and thoroughly incorporated into the entire depth of the prepared seedbed. The incorporation of the lime may form a part of the tillage operation specified above. 1.20 The fertilizer shall be incorporated into the upper three or four inches of the prepared seedbed. This can be done just prior to the last tillage operation or just prior to seeding, but in no case, will it be applied more than three days before seeding or before the lime is applied. Distribution by means of an approved seed drill equipped to sow seed and distribute fertilizer at the same time will be acceptable. When hydroseeding equipment is used for planting operations, fertilizer shall be applied simultaneously with seed using the above rate of application. 1.21 When conditions are such, by reason of draught, high winds, excessive moisture, or other environmental factors are such that satisfactory results are not likely to be obtained, the work shall be stopped and resumed only when conditions are favorable. If inspection during seeding operations, or after there is a show of green, indicates that strips wider than the space between rows planted have been left, or other areas skipped, additional seed shall be sown on these areas. 1.22 Straw or hay mulch shall be anchored in place by uniformly spraying the straw with the herein before specified asphalt material at the rate of 0.10 gallon per square yard. 1.23 The area shall be protected against foot and vehicular traffic by erecting adequate barricades immediately after seeding is completed, and by placing warning signs of an approved type. 1.24 The Contractor shall be responsible for the proper care of the seeded area during the period when vegetation is being established. In the vent of an erosive rain before an adequate stand of vegetation is established, damaged areas shall be repaired, limed, fertilized, seeded, and mulched wholly at the Contractor's expense. 1.25 The Contractor will restore all areas upon completion of project including the removal of sedimentation and erosion control devices and restoration of the wet detention basin. Restoration of the basin will include restoring the basins to the design depth and re -seeding and mulching where the basins are disturbed. � 7 R STORM WATER MANAGEMENT NARRATIVE FOR WAVES APPAREL NC HIGHWAY 50/210 TOWN OF SURF CITY PENDER COUNTY, NORTH CAROLINA RECEIVED J U N 19 2003 DWQ Pxoi # : c Sa /o 515 PREPARED FOR: II&D PROPERTIES, LLC 14418 OCEAN HIGHWAY PAWLEYS ISLAND, SOUTH CAROLINA 29585 PREPARED BY: KEITH P.

The project site is a total of 3.143 acres. The property is located on the west -side of NC Highway 50/210, approximately 1000 linear feet south of the intersection of N.C. Highway 50 and 210, Town of Surf City, Pender County. The storm water controls for the project include vegetated buffers, vegetated swales and wet detention basin. There is no off -site storm water contributing to this site. The project wet detention basin will discharge to a ditch located in a dedicated street right of way. The project is located in a watershed that drains to Beckys Creek, classified as SA waters. The site is more than '/z- mile from SA waters. The project provides easements for the storm water conveyances. H&D Properties, LLC, 14418 Ocean Highway, Pawleys Island, South Carolina, is responsible for the construction, operation and maintenance of the storm water system. This property has been cleared and has been developed. A storm water detention basin previously constructed on the site will be filled in and graded to drain to the detention basin proposed in this application. The existing impervious surface area is .839 acres. No additional impervious surfaces are proposed. The percentage of impervious surface area for the site is approximately 26.7%, requiring the site to be developed as a high -density site in accordance with NC Storm Water Regulations. According to the Soil Survey of Pender County, the site soils consist of the Onslow series described as moderately well drained. The seasonal high water table is estimated to be located at 4 to 5-feet below the ground surface. The project water and sewer utilities are connected to local public utility systems. Storm Water Management: During construction, silt fences are to be constructed on site to manage runoff. The proposed wet detention basin will be constructed to the rear of the property outside an existing pond. The detention basin discharge point is located 50 feet from the existing pond high water mark. The wet detention basin has been designed to capture the first one - inch of storm water runoff from each rainfall event. The wet detention basin calculations are enclosed. The wet detention basin has one curb inlet located on the east -side of the basin. The runoff from the site flows to swales located near the property lines that drain to the curb inlet. The storm water will flow into the basin forebay, design volume approximately 20% of the total basin design volume. From the forebay, the storm'water will flow over a r spillway along the width of the basin into the main basin pool. The basin has a permanent storage depth of 5-feet. The top of the permanent pool is provided with a planting shelf with a slope of 6:1. The 1-inch of rainfall is contained in l .l -foot above the permanent pool. A basin freeboard of 1.4-foot and an emergency spillway are to be provided. The basin side slope will be 3:1 above the permanent pool. The basin storage volume above permanent pool will be discharged through a 1-114-inch diameter orifice located in the basin outlet structure. The 1-1/4-inch diameter outlet will discharge the 1-inch of rainfall over a four -day period. The outlet structure is equipped with a 6-inch drain located at the bottom of the structure for draining the basin. From the outlet structure, the basin can be pumped out for any required cleaning or maintenance. 1). Keith P.

This survey is to be compared to the plan prepared for the original land disturbance permit. To our knowledge, the site was not developed prior to the construction of the Waves Beach Wear store. 2. Upon comparing the as -built drawing to the construction plans, the Engineer will contact Ms. Noelle Lutheran to discuss the findings and to obtain any input she may have in regard to the site. 3. Within two weeks of this correspondence, a letter will be prepared and sent to your attention with the Engineer's recommendation for the owner to either revise the existing storm water management plan in accordance with the State's request for additional information dated July 17, 2001 or prepare a new storm water management application. This correspondence will also outline the time required to construct the recommended improvements. 4. A revised plan and revised application, if needed, will be provided to the State within four weeks of the State's acceptance of the Engineer's recommendation. 5. It is the intent of the owner to be in full compliance with the storm water permit and the approved erosion control plan. .._ if �' •eff ' � �' ! S. I _,. Swi .' • r .T. , f, r f:!'. 'f t, r.

A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Please either delineate all wetlands on site, disturbed or undisturbed, or note on the plans that none exist. 2. The corporation provided on the application is not listed with the NC Secretary of State. Please provide a copy of the incorporation papers and a list of the officers. I am unable to issue a permit to a corporation that is not registered in North Carolina. The mailing address for the applicant is PO Box 3228 , Myrtle Beach SC on the plans, but the application has a Pawley's Island address. Please provide the mailing address of the corporation as registered with the Secretary of State. 4. Please provide a 3:1 L:W flow path ratio in the pond. The supplement item ( f ) is initialed, indicating that this item has been provided, however, the pond dimensions provide for only a 2 ratio. Please label the radii of the permanent pool contour. 6. Please dimension the sidewalk area around the building, the width of the driveway that leads to the rear of the building, and the rear parking / loading area. 7. Please provide a larger orifice. The calculations indicate that the diameter should be between 0.57" and 0.94", but a 0.5" has been chosen. The sediment cleanout benchmark on the supplement is intended to be reported as a depth, not an elevation.

Division of Water Quality 127 Cardinal Drive Extension Wilmington. N.C. 28405 Re: Waves Beachwear Stormwater Permit No. 010515 Pender County Dear Mr. Shiver, RECEIVED APR 0 1 2002 BY: We are in receipt of your Notice of Violation dated March 13, 2002 regarding the referenced project. That letter indicates that your stag' "observed the unpermitted construction of building, parking lot and wet detention pond". Please accept this letter as our explanation for the alleged violation. I will provide a brief summary of events in hopes of clarifying our efforts to achieve compliance: Early in 2001, my site design consultant, John L. Pierce & Associates, prepared and submitted Site Plan for the project to the Town of Surf City. The project, as designed, disturbed less than one acre, therefore, was not subject to NCDENR Land Quality or Stormwater Review. The project as designed, however; was subject to Town of Surf City Stormwater Requirements. A pond, in accordance with those local requirements was incorporated into the design. On March 12, 2001 NCDENR Land Quality staff conducted a site inspection. Based upon the inspection report, it appeared that the site was in compliance at that time. The Sedimentation Inspection Report filed by NCDENR staff indicates that clearing was limited to 0.82 acres. It would appear, therefore, that NCDENR approval of stormwater facilities would not be necessary as of that particular date. At some time after March 12, 2001 (no written documentation was provided), NCDENR staff indicated to my site contractor that submission to NCDENR Land Quality would be required. On May 10, 2001, my site design consultant submitted a Sedimentation and Erosion Control Plan and associated application package to NCDENR. r Also on May 10, 2001, my site design consultant submitted a Stormwater Permit Application, including $420.00 fee, to your office. On May 23, 2001 NCDENR issued Letter of Approval of the Sedimentation and Erosion Control Plan. i In response to review comments from your office, on June 5, 2001, my site design consultant submitted a revised application package. This submittal included all required modifications to the existing pond to comply with NCDENR requirements. %- Due to cost and space requirements, my site contractor decided in mid October 2001 to eliminate the pond and design and infiltration system conforming: to NCDENR requirements. My site desigmn consultant was authorized to complete the infiltration system design in November 2001. On March 4, 2002 my site design consultant submitted a revised Stormwater Plan and application package. As your office had not vet issued a Stormwater Permit for the project, I did not think that another S420 application fee would be required. On March 13, 2002, my application package was returned as "Incomplete" as it did not included the required S420.00 fee. I am hopeful that you will agree that enforcement action is not warranted in this case as NCDENR review and approval of the project was not required when construction was initiated. In addition, please consider that I have done everything within my power to obtain the necessary approvals and permits once your staff came to the conclusion that Eros ionlSedimentation and Stormwater permitting would be required. There has been no attempt to contest or circumvent your requirements. Quite to the contrary, I have attempted at all times to cooperate and achieve compliance as quickly as possible. To achieve compliance with NCDENR stormwater requirements. I propose the following Plan of Action: Plan of Action Action 1. Resubmit stormwater permit application to your office 2. Obtain NCDENR approval of application (3 month review) 3. initiate Construction of permitted facilities 4. Complete Construction of permitted facilities 5. Submit Engineer's Certification Date June 1, 2002. September 1, 2002 October 1, 2002 November 1, 2002 December 1, 2002 I very much appreciate your understanding and cooperation in this matter.

September 19, 2001 Project Descrintion The project consist of construction of a retrial building and associates sitework on a 3.12 acre tract located on N.C. Highway 50 in Surf City, NC. The project will be constructed on a 1.5 acre portion of the tract. Construction will include one retail building (beachwear & accessories), asphalt parking lot, water and sewer utilities and concrete sidewalks. This site is located 0. 59 miles from the closest surface waters, Becky's Creek 2. Desi ig t Requirements Project will be designed in accordance with NC Administrative Code Section 15A NCAC 2H.1000 — Stormwater Management. This site is in the category of "development activities within coasial counties except those areas draining to Outstanding Resource Waters or within one-half mile of and draining to SA water". Due to density, the project is considered "high density development ". In accordance with regulations, an infiltration system designed to accommodate V of rainfall will be required. Furthermore, runoff in excess of the design volume must flow overland through a vegetative filter. In accordance with "high density" requirements, runoff from all impervious surfaces, including existing, must be treated. 3. Impervious Drainage Areas Existing and proposed impervious areas are as follows: lmt)ervious Area (Existin Buildings 12,078 SF Parking (incl dumpster) 22,825 SF Sidewalks 1,928 SF Subtotal 36,831 SF Impervious Area (Future) Parking 6,294 SF Total Impervious Area — 43,125 SF 4. Required System Dimensions The existing soils are clean, well graded, coarse to medium sands which typically exhibit permeability coefficients in the range of 10" t0 10-z. Assume conservatively that existing soils have a minimum hydraulic conductivity of 0.52 in/hr (minimum acceptable for infiltration). Existing soils, however, appear to be much more conductive as evidenced by the fact that existing pond levels recede to approximately elevation 24.0 within 24 hours of any significant rainfall event. a. Design Storage Volume Storage Volume = Design Depth x Impervious Area _ (I" / 12) x 43,125 = 3,594 CF b. Base Area Requirement infiltrations systems must be designed to draw down the design storage volume within five days. Tentatively size system footprint for a maximum 3 day drawdown period: Drawdown Period = (Storage Volume x 12) / (Area x Hyd. Conductivity) where: Drawdown Period = 3 days or 72 hours Storage Volume = 3,594 (from above) Hyd. Conductivity = 0.52 (assumed above) Base Area = (3,594 CF x 12)/(72 hr x 0.52 in/hr) = 1,152 SF c. Number of Infiltration Units Prefabrication "infiltrator Units" are proposed. Each unit provides a footprint area of 17.70 SF. Base number of units required is computed as follows: Number = 1,152 SF / 17.7 SF/unit 65 units Use 64 units ( 8 rows by 8 columns) d. Actual Area Provided Areas = 64 units x 17.7 SF/unit 1,132.8 SF e. Actual Drawdown Provided Drawdown Period,,,,,,i = (Storage Volume x 12) / (Area x Hyd. Conductivity) (3,594 CF x 12) / (1,132.8 SF x 0.52 in/hr) = 73.2 hours (3.05 days — O.K., , 5days) f. Actual Volume Provided Each unit provides a storage volume of 122 gals (16.3 CF) Volume.,,., = Infiltrator Volume + collector pipes volume(surcharged portions only), = (64 units x 16.3) + (22 CF + 144 CF + 15 CF) =1,224 CF g. Additional Volume Required Volume,"t,.„i = Storage Volume - Volume,, = 3,594 CF - 1,224 CF = 2,370 CF Provide depressed storage basin with minimum 2,370 CF capacity. ........... _.: w . _ _ _ .........-. NARRATIVE FOR SEDDvIENTATION AND EROSION CONTROL WAVES BEACHWEAR - SURF CITY, NC H&D PROPERTIES INC. TOPSAIL TWP., PENDER, NORTH CAROLINA MAY, 2001. The Waves Beachwear site contains 3.12 acres and is located on N.C. Highway 50 approximately 0.30 miles South of the intersection of N.C. Highway 50 and N.C. I-Eahway 210. The site is bound to the West by an existing pond, to the South & North by commercial property and to the East by N.C. Highway 50. The site will have limited grading and will be restricted to only site construction as shown on the attached plans. The land disturbing activities shall take place as shown on the plans. During all phase of the construction the sediment must be contained on the site. The soil exposed area shall be seeded according to the plans and Seeding Specifications. The construction will begin around May, 2001 _ The grading and seeding should be completed within approximately 90 days from the date the land disturbing activities begins. In order to prevent excessive soil erosion and siltation a vegetative ground cover should be established as soon as possible. The Contractor small complete the grading to the proper cross section as soon as possible and perform seeding work within two (2) worldng days after any phase of the construction is complete. Mulching will be required on all seeded areas. SITE PREPARATION Grading or clearing of the areas should be done in such a way to leave the soil in the best possible condition for seeding. This includes leaving as much topsoil as possible or replacing where needed to modify the condition. 2. Where feasible, grade and shape slopes to a 3:1 ratio slope or flatter to permit the use of conventional equipment for seedbed preparation, seeding, mulch application and anchoring and maintenance operations. Grading and shaping is desirable, but not necessary when seeding is done by other than conventional means, such as with hydraulic equipment or by hand. 4. No seedbed preparation is necessary on most soil and site conditions where seeding is done immediately after excavation or spoil spreading is completed. Where this type of seeding is done, the excavation work should be completed during the optimum seeding date for the desired plant or rnb=re of plants. 5. Where adverse soil conditions require modifications, apply at least 3 to 4 inches of topsoil or similar soil material. The use of topsoil should be considered where the soil texture at the site is sandy clay, silty clay, or clay. Ripping prior to the addition of new material is usually needed. 6. Remove all woody material, loose rock, and other obstructions that may interfere with planned seeding and maintenance operations. LIME AND FERTILIZER Where soils are reasonably uniform, lime and fertilize according to soil test- In the absence of a soil test, apply 2 tons finely ground dolomitic limestone per acre (92 pounds per 1,000 square feet) and 500 to 800 pounds of 20% superphosphate or equivalent per acre (12 to 18 pounds per 1,000 square feet). Additional amounts and analysis of fertilizers to use at seeding are: Grasses alone - 800 to 1,000 pounds per acre of I0-10-10, or equivalent (18-23 pounds per 1,000 square feet). 2. Grasses and legurnes or legumes alone - 800 to 1,000 pounds per acre of 5-10-10 or equivalent (18 - 23 pounds per 1,000 square feet). Normally an additional application of 30-50 pounds of nitrogen per acre is needed within three (3 ) to twelve (12) months to establish grass plantings. Application should be timed to growing cycle of the species being established. SEEDBED PREPARATION Work lime ad fertilizer into the soil where conventional equipment can be used. Use disk or similar equipment to prepare to depth of 3 - 4 inches. Use ripper if necessary. 2- Lime and fertiiizer may be applied with seed mixture when a hydroseeder is used and where mulch will be applied. Seedbed preparation may not be necessary where hydro -seeding equipment is used. 3. Slopes that are too steep for conventional equipment (2:1 or steeper) should be with hydra -seeding equipment. MG Where hydro -seeding equipment is not available for use on steep slopes, scarify the soil surface with a chain harrow, pick chain, grader blades with chisels, hand tools, or other equipment that will pit the soil or make trenches approximately 1-2 inches deep, 6-12 inches apart across the slope in which the seed can lodge and germinate_ SEED SPECIFICATIONS 1. Seed specifications on contracts: a. Specifications shall state the minimum seed purity percentage and minimum germination percentage that is acceptable for species being used. b. Seed containing prohibited or restricted noxious weeds may not be accepted. C. All seed shall be labeled to show that it meets the requirements of North Carolina Seed Law. d. All seed used shall have been tested within six (6) months immediately preceding the date of seeding. e. The inoculate for treating legume seed shall be prepared specifically for the species. Inoculates shall not be used later than the date indicated on the container. Twice the supplier's recommended rate of inoculate will be used on dry seedings; four times the recommended rate if hydro -seeded. 2. Where hydraulic seeding equipment is used, seed, fertilizer, and wood -fiber mulch materials are mixed into a slurry with water_ Care should be used to spread the mixture evenly and soon after the mixture is made. Keep the mixture well agitated when seeding. ;. Where conventional equipment is used, seed shall be applied uniformly with cultipacker-seeders, drills, rotary seeders, or other mechanical seeders. Any equipment that will apply seed uniformly is acceptable. Seedings may be done by hand on areas where it is not practical and feasible to use equipment. When seeding by hand, sow one-half in one direction and the other half at right angles to the first. Cover seed to a depth of approximately 1/2 to 1 inch, depending on the size of the seed. When cultipacker-seeder is not used, firm seedbed and cover seed with cultipacker or similar equipment, before or after mulching depending upon type mulch used and method of anchoring mulch that is used. 4_ On dikes, ditchbanks, etc_, seeding may be made by broadcasting the seed on spoil areas and side slopes immediately following excavation or spoil spreading. ESTABLISHN= WITH VEGETAUVE MATERIAL l . Areas that will be subject to traffic and routine mowing in residential, commercial, or industrial developments may be established by using grass stolons (sprigs or runners). Precaution should be used to make certain only fresh, moist planting material is used. A Planting Methods for Bermudagrass (1) Prepare a smooth seedbed, shred stolons, broadcast and disk into the top 1 - 2 inches of soil, and firm the soil. Plantings may be made with a transplanter or hand planting tools. (2) Open shallow furrow 24 - 30 inches apart, drop clumps of stolons in furrow and cover I - 2 inches deep, and smooth and firm the soil. (3) Fill burlap bags with Bermuda.gras roots and soil. Place bags 10 - 15 feet apart in small gullies or scouring ditches. (4) Spread 3 - 4 inches of soil filled with Bermudagrass roots and firm the soil. 2. Crownvetch, kudzu, maidencane, and similar plants may be planted in furrows; excavated holes; or with spade, dibble or similar hand tools. When planting in excavated holes, dig holes large enough to allow roots to spread out to full length. When planting in "pot" holes or furrows, place about a level tablespoon of fertilizer per plant in the bottom of the hole or furrow and cover with fresh soil before planting. Set plants slightly deeper than they grew in the nursery and firm the soil. If vegetative materials are not dormant, water during planting operations.. MULCHLNG Mulch is essential on steep, erosive sites where plant establishment may be expected to be different. On some moderately fertile to fertile sites planted at optimum time for the species, mulch may be omitted. It is the responsibility of the conservationist to determine i- the need for mulching based on the hazards involved; consider materials available; and determine specifications for the job. 1. Mulchine, Materials: A Dry, unchopped„ unweathered small grain straw or hay free of seeds of competing plants - Spread at the rate of 1 - 2 tons per acre depending upon the site and season. Evenly spread mulch over the area by hand or mechanical equipment. Apply mulch uniformly so that about 25% of the around surface is visible. B. Sericea lespedeza seed bearing stems at a rate of three tons per acre - This mulch may be applied green or dry but must contain mature seed. Liming, fertilizing, and land preparation should 'precede apphcation.of the sericea mulch. C. Broomsedge hay mulch - Spread where it is desirable to establish this native plant. D. Shredded or hammermilled hardwood bark - Spread at a rate of 35 cubic yards per acre. On slopes of 2:1 or steeper, increase rate to 40 cubic yards per acre. Do not apply asphalt material to tack the hardwood bark E_ Local materials such as burlap and pine boughs - Cover entire area; secure in place if flowing water is involved. Do not us green pine branches were pine trees are to be planted because of possible insect or disease injury to plantings. F. Barnyard manure and bedding - Apply uniformly so that about 25% of the ground surface is visible. G. Jute matting is a coarse, open -mesh material woven of heavy jute twine. It may be used in place of mulch or sod and has the strength to withstand waterflow. It is an accepted practice to sow half the seed before placing the matting. Sow the remaining half after the matting is laid. See the manufacturer's specifications for installing. H. ' Wood fiber (excelsior) is available as mulch material to be blown on after seeding or as a mating to be stapled on steep slopes, waterways, etc. Seed the manufacturer's specifications for installing. I. Wood cellulose fiber mulch is mixed with seed, fertilizer, and water. The resulting slurry is sprayed on with hydraulic seeding equipment. Use at the rate of 500 pounds per acre where straw or hay is to be applied. Use at the rate of I,000 to 1,500 pounds per acre without other mulching materials. Applied in a slurry, wood cellulose fiber mulch is self -anchoring. I Other commercial products, such as fiberglass and various kinds of nettings, are available. Manufart+ur-er's dire=sors should be followed for applying and securing in place. 2. Mulch Anchoring Methods Anchor mulch immediately after placement to minimise loss by wind and water. Consider size of area, type of site, and cost and select one of the following: A_ Mulch anchoring tool with a series of flat notched disks that punch and anchor mulch material into the soil. A regular farm disk weighted and set nearly straight may substitute but will not do a job comparable to the mulch anchoring tool. This disk should not be sharp enough to cut up the mulch. The soil should be moist, free of stones or roots and loose enough to permit penetration to a depth of 3 inches. Operate as near as practical to the contour. B. Mulch neetings - Staple light weight paper, jute, cotton, plastic, or wire' nettings to the soil surface according to manufacturer's specifications. These nettings are usually in rolls 3 to 4 feet wide and up to 300 feet long. C. Peg and twine - Drive 8 to 10 inch wooden pegs to within 2 to 3 inches of the soil surface every 4 feet in all directions. Stakes may be driven before or after applying mulch. Secure mulch to soil surface by stretching twine. between pegs in a criss-cross within a square pattern. Secure twine around each peg with two or more round turns. Poles and stakes may also be used to. secure brush in place. D. Silt - With a square pointed spade, cut mulch into the surface soil in contour rows IS inches apart. E. Asphalt mulch tie -down - Asphalt sprayed uniformly on the mulch as it is ejected from the blower is more effective than applied as separate operation. Apply so area has uniform appearance. Rates of application will vary with conditions. The higher the grade number assigned each type of asphalt the higher the percentage of asphalt residue. Asphalt should not be used in freezing weather. (1) Emulsified Asphalt - Apply uniformly 0.04 to 0.08 gallons per square yard or 200 to 400 gallons per acre of rapid setting .... ------------- (RS-1, CRS-1, RS-2, or CRS-2), medium setting (MS-1, MS-2, or CMS-2); slow setting (SS-1 or CSS-1). Rapid setting (RS or CRS) is formulated for curing in less than 24 hours even during periods of high humidity. Best for spring and fall. Medium setting (MS or CMS) is formulated for curing within 24 to 48 hours - Slow setting (SS or CSS) is formulated for use during hot, dry weather with 48 hours or more curing time. Note - In areas of playing children or pedestrian traffic, asphalt application could cause problems of"tr-acldng in" on rugs; damage shoes, clothing, etc. Use types RS or CRS -to minimize problem. F. Mulch can be anchored with rye for fall plantings or millet for summer plantings. Use 114 to 1/2 bushel or rye or 15 pounds of millet per acre broadcast ahead of mulch application - Maintenance is the most important controllable factor in retaining an e$Fective vegetative cover. Control of Competition Competitive weed growth during the period of establishment should be controlled by mowing and/or with herbicides. When chemicals are used, . follow current North Carolina Agricultural Experiment Station's chemical weed control recommendations and adhere strictly to instructions on label- Z- Irriszation If soil moisture is deficient, supply new planting with adequate water (3-4" penetration) for plant growth at 10-day intervals, if needed, until they are established. This -is most important on late season plantings, in abnormally dry or hot seasons. SEEDING VARIETY During the month of June, July and August a temporary vegetative seeding application will be used due to the season of the year. The seeding recommendation for this time of year is Sudangrass applied at the rate of 35-45 pounds, 1,000 pounds of 10-10-10 fertilizer, and 2,000 pounds of lime per acre. During the months of September, October, and November if there is any remaining areas that have not been stabilized the seeding application of tail fescue' will be applied at the rate of 40-60 pounds, 1,000 pounds of 10-10-10 fertilizer, and 2,000 pounds of lime per acre. The tall fescue shall also be applied to the areas that were seeded in the months of June, July and August.

Repair eroded areas immediately, re -seed as necessary to maintain adeQuate vegetative cover, mow vege acve cove: to maintain a maximum height or six inches, and remove trash and blockages as needed to maintain sysie:n perfor nark.-.. 3. - Remove accumulated sediment annually or when depth is reduced to 757o of trie original design depth. Restore depth to ocginai design depth widiout over-excavat ng. Over -excavating may cause trip required water table separation to be reduced and may compromise the ability or the systern to pe.iorm as designed. I"ne water Ievel in any monitor-ing wells will be recorded after a 1 inch rainfall event and at least once a month. Chronic high ware.- table elevarions (wirhin 1 foot of the bottom of the system for a period of three months) shall be reported to DWQ immediately. 3. if DWQ determines that the system is failing, the system will immediately be repaired or replaced to original design specifications. If the system cannot be repaired to perform its design function, outer stormwater control devices as allowed by NCAC 3H .1000 must be designed, approved and constructed. o. Remove accumulated sediment from the infiltration systern annually or when depth in the unit is reduced to 75% of the original design depth. The system shall be restored to the original design depth without aver-excavating.Over-excavating Oveexcavating may cause the required water table separation to be reduced and may compromise the ability of the system to perform as designed. Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will adversely imuacr water Quality (i.e. stockpiling near a sto=water tieatment device or stream, etc.). A benchmark small be established in the infiltration system. The benchmark will document the original design depth so that accurate sediment accumulation readings can be taken. The measuring device used to determine :he depth at the benchmark shall be such that it will rive an accurate depth reading and not readily penetrate into accumulated sediments. v When the depth at the benchmark reads the accumulated sediment shall be removed u otn the system. .

September 19, 2001 Project Description The project consist of construction of a retrial building and associates sitework on a 3.12 acre tract located on N.C. Highway 50 in Surf City, NC. The project will be constructed on a 1.5 acre portion of the tract. Construction will include one retail building (beachwear & accessories), asphalt parking lot, water and sewer utilities and concrete sidewalks. This site is located 0.59 miles from the closest surface waters, BecAy's Creek. 2. Desk Requirement* Project will be designed in accordance with NC Administrative Code Section 15A NCAC 214.1400 — Stormwater Management. This site is in the category of "development activities within coastal counties except those areas draining to Outstanding Resource Waters or within one-half mile of and draining to SA water". Due to density, the project is considered "high density development". In accordance with regulations, an infiltration system designed to accommodate 1" of rainfall will be required. Furthermore, runoff in excess of the design volume must flow overland through a vegetative filter. In accordance with "high density" requirements, runoff from all impervious surfaces, including existing, must be treated. 3. Impervious Drainage Areas Existing and proposed impervious areas are as follows: impervious Area (Existin Buildings 12,078 SF Parking (incl dumpster) 22,825 SF Sidewalks 1,928 SF Subtotal 36,831 SF Impervious Area (Future) Parking 6,294 SF Total Impervious Area — 43,125 SF 4. Required System Dimensions The existing soils are clean, well graded, coarse to medium sands which typically exhibit permeability coefficients in the range of 191 t0 10-2. Assume conservatively that existing soils have a minimum hydraulic conductivity of 0.52 inthr (minimum acceptable for infiltration). Existing soils, however, appear to be much more conductive as evidenced by the fact that existing pond levels recede to approximately elevation 24.0 within 24 hours of any significant rainfall event. a. Design Storage Volume Storage Volume = Design Depth x Impervious Area JI '7 Ll %I L (1" / 12) x 43,125 = 3,594 CF b. Base Area Requirement Infiltrations systems must be designed to draw down the design storage volume within five days. Tentatively size system footprint for a maximum 3 day drawdown period: Drawdown Period = (Storage Volume x 12) / (Area x Hyd. Conductivity) where: Drawdown Period = 3 days or 72 hours Storage Volume = 3,594 (from above) Hyd. Conductivity = 0.52 (assumed above) Base Area = (3,594 CF x 12)/(72 hr x 0.52 in/hr) = 1,152 SF c. Number of Infiltration Units Prefabrication "Infiltrator Units" are proposed. Each unit provides a footprint area of 17.70 SF. Base number of units required is computed as follows: Number = 1,152 SF / 17.7 SF/unit 65 units Use 64 units ( 8 rows by 8 columns) d. Actual Area Provided Area,mw = 64 units x 17.7 SF/unit = 1,132.8 SF e. Actual Drawdown Provided Drawdown Period,d,„i = (Storage Volume x 12) / (Area x Hyd. Conductivity) _ (3,594 CF x 12) / (1,132.8 SF x 0.52 in/hr) = 73.2 hours (3.05 days — O.K., , 5days) f. Actual Volume Provided Each unit provides a storage volume of 122 gals (16.3 CF) Volume.M., = Infiltrator Volume + collector pipes volume(surcharged portions only) (64 units x 16.3) + (22 CF + 144 CF + 15 CF) =I,224 CF g.

TOPSAIL TWP., PENDER, NORTH CAROLINA MAY, 2001 The Waves Beachwear site contains 3.12 acres and is located on N.C. Highway 50 approximately 0.30 miles South of the intersection of N.C. Highway 50 and N.C. Highway 210. The site is bound to the West by an existing pond, to the South & North by commercial property and to the East by N.C. Highway 50. The site will have limited grading and will, be restricted to only site construction as shown on the attached plans. The land disturbing activities shall take place as shown on the plans. During all phase of the construction the sediment must be contained on the site. The soil exposed area shall be seeded according to the plans and Seeding Specifications. The construction will begin around May, 2001. The grading and seeding should be completed within approximately 90 days from the date the land disturbing activities begins. In order to prevent excessive soil erosion and siltation a vegetative ground cover should be established as soon as possible. The Contractor shall complete the grading to the proper cross section as soon as possible and perform seeding work within two (2) working days after any phase of the construction is complete. Mulching will be required on all seeded areas. SITE PREPARATION Grading or clearing of the areas should be done in such a way to leave the soil in the best possible condition for seeding. This includes leaving as much topsoil as possible or replacing where needed to modify the condition. 2. Where feasible, grade and shape slopes to a 3:1 ratio slope or flatter to permit the use of conventional equipment for seedbed preparation, seeding, mulch application, and anchoring and maintenance operations. 3. Grading and shaping is desirable, but not necessary when seeding is done by other than conventional means, such as with hydraulic equipment or by Band. 4. No seedbed preparation is necessary on most soil and site conditions where seeding is done immediately after excavation or spoil spreading is completed. Where this type of seeding is done, the excavation work should be completed during the optimum seeding date for the desired plant or mixture of plants. 5. Where adverse soil conditions require modifications, apply at least 3 to 4 inches of topsoil or similar soil material. The use of topsoil should be considered where the soil texture at the site is sandy clay, silty clay, or clay. Ripping prior to the addition of new material is usually needed. 6. Remove all woody material, loose rock, and other obstructions that may interfere with planned seeding and maintenance operations. LIlviE AND FERTILIZER Where soils are reasonably uniform, lime and fertilize according to soil test. In the absence of a soil test, apply 2 tons finely ground dolomitic limestone per acre (92 pounds per 1,000 square feet) and 500 to 800 pounds of 20% superphosphate or equivalent per acre (12 to 18 pounds per 1,000 square feet). Additional. amounts and analysis of fertilizers to use at seeding are: 1. Grasses alone - 800 to 1,000 pounds per acre of 10-10-10, or equivalent (18-23 pounds per 1,000 square feet). 2. Grasses and legumes or legumes alone - 800 to 1,000 pounds per acre of 5-10-10 or equivalent (18 - 23 pounds per 1,000 square feet). 3. Normally an additional application of 30-50 pounds of nitrogen per acre is needed within three (3) to twelve (12) months to establish grass plantings. Application should be timed to growing cycle of the species being established. SEEDBED PREPARATION Work lime ad fertilizer into the soil where conventional equipment can be used. Use disk or similar equipment to prepare to depth of 3 - 4 inches. Use ripper if necessary. 2. Lime and fertilizer may be applied with seed mixture when a hydroseeder is used and where mulch will be applied. Seedbed preparation may not be necessary where hydro -seeding equipment is used. Slopes that are too steep for conventional equipment (2:1 or steeper) should be with hydro -seeding equipment. Where hydro -seeding equipment is not available for use on steep slopes, scarify the soil surface with a chain harrow, pick chair grader blades with chisels, hand tools, or other equipment that will pit the soil or make trenches approximately 1-2 inches deep, 6-12 inches apart across the slope in which the seed can lodge and germinate. SEED SPECIFICATIONS Seed specifications on contracts: a. Specifications shall state the minimum seed purity percentage and minimum germination percentage that is acceptable for species being used. b. Seed containing prohibited or restricted noxious weeds may not be accepted. c. All seed shall be labeled to show that it meets the requirements of North Carolina Seed Law. d. All seed used shall have been tested within six (6) months immediately preceding the date of seeding. e. The inoculate for treating legume seed shall be prepared specifically for the species. Inoculates shall not be used later than the date indicated on the container. Twice the supplier's recommended rate of inoculate will be used on dry seedings; four times the recommended rate if hydro -seeded. ?. Where hydraulic seeding equipment is used, seed, fertilizer, and wood -fiber mulch materials are mixed into a slurry with water. Care should be used to spread the mixture evenly and soon after the mixture is made. Keep the mixture well agitated when seeding. Where conventional equipment is used, seed shall be applied uniformly with cultipacker-seeders, drills, rotary seeders, or other mechanical seeders. Any equipment that will apply seed uniformly is acceptable. Seedings may be done by hand on areas where it is not practical and feasible to use equipment. When seeding by hand, sow one-half in one direction and the other half at right angles to the first. Cover seed to a depth of approximately 1/2 to 1 inch, depending on the size of the seed. When cultipacker-seeder is not used, firm seedbed and cover seed with cultipacker or similar equipment, before or after mulching depending upon type mulch used and method of anchoring mulch that is used. 4. On dikes, ditchbanks, etc., seeding may be made by broadcasting the seed on spoil areas and side slopes immediately following excavation or spoil spreading. ESTABLISHMENT WITH VEGETATIVE MATERIAL Areas that will be subject to traffic and routine mowing in residential, commercial, or industrial developments may be established by using grass stolons (sprigs or runners)_ Precaution should be used to make certain only fresh, moist planting material is used. A. Planting Methods for Bermudagrass (1) Prepare a smooth seedbed, shred stolons, broadcast and disk into the top 1 - 2 inches of soil, and firm the soil. Plantings may be made with a transplanter or hand planting tools. (2) Open shallow furrow 24 - 30 inches apart, drop clumps of stolons in fiuTow and cover 1 - 2 inches deep, and smooth and firm the soil. (3) Fill burlap bags with Bermudagras roots and soil. Place bags 10 - 15 feet apart in small gullies or scouring ditches. (4) Spread 3 - 4 inches of soil filled with Bermudagrass roots and firm the soil. 2. Crownvetch, kudzu, maidencane, and similar plants may be planted in furrows; excavated holes; or with spade, dibble or similar hand tools. When planting in excavated holes, dig holes large enough to allow roots to spread out to full length_ When planting in "pot" holes or furrows, place about a level tablespoon of fertilizer per plant in the bottom of the hole or furrow and cover with fresh soil before placating. Set plants slightly deeper than they grew in the nursery and firm the soil. If vegetative materials are not dormant, water during planting operations. I UT UfWOa!fU0I Mulch is essential on steep, erosive sites where plant establishment may be expected to be different. On some moderately fertile to fertile sites planted at optimum time for the species, mulch may be omitted, it is the responsibility of the conservationist to determine ----------- _ ._.._ . - -- - -- . the need for mulching based on the hazards involved; consider materials available; and determine specifications for the jab. 1. Mulching Materials: A. Dry, unchopped„ unweathered small grain straw or hay free of seeds of competing plants - Spread at the rate of 1 - 2 tons per acre depending upon .the site and season. Evenly spread mulch over the area by hand or mechanical equipment. Apply mulch uniformly so that about 25% of the ground surface is visible. B. Sericea lespedeza seed bearing stems at a rate of three tons per acre - This mulch may be applied green or dry but must contain mature seed. Liming, fertilizing, and land preparation should precede apphcation.of the sericea mulch. C. Broomsedge hay mulch - Spread where it is desirable to establish this native plant. D. Shredded or hammernulled hardwood bark - Spread at a rate of 35 cubic yards per acre. On slopes of 2:1 or steeper, increase rate to 40 cubic yards per acre. Do not apply asphalt material to tack the hardwood bark. E. Local materials such as burlap and pine boughs - Cover entire area; secure in place if flowing water is involved. Do not us green pine branches were pine trees are to be planted because of possible insect or disease injury to plantings. F. Barnyard manure and bedding - Apply uniformly so that about 25% of the ground surface is visible. G. Jute matting is a coarse, open -mesh material woven of heavy jute twine. It may be used in place of mulch or sod and has the strength to withstand waterflow. It is an accepted practice to sow half the seed before placing the matting. Sow the remaining half after the matting is laid. See the manufacturer's specifications for installing. H. ' Wood fiber (excelsior) is available as mulch material to be blown on after seeding or as a mating to be stapled on steep slopes, waterways, etc. Seed the manufacturer's specifications for installing. X. Wood cellulose fiber mulch is mixed with seed, fertilizer, and water. The resulting slurry is sprayed on with hydraulic seeding equipment.

Applied in a slurry, wood cellulose fiber mulch is self -anchoring. Other commercial products, such as fiberglass and various kinds of nettirgs, are available. Manufacturer's directions should be followed for applying and securing in place. 2. Mulch Anchoring Methods Anchor mulch immediately after placement to rninimize loss by wind and water. Consider size of area, type of site, and cost and select one of the following.- A- Mulch anchoring tool with a series of flat notched disks that punch and anchor mulch material into the soil. A regular farm disk weighted and set nearly straight may substitute but will not do a job comparable to the mulch anchoring tool. This disk should not be sharp enough to cut up the mulch. The soil should be moist, free of stones or roots and loose enough to pernut penetration to a depth of 3 inches. Operate as near as practical to the contour. B. Mulch neetings - Staple light weight paper, jute, cotton, plastic, or wire nertings to the soil surface according to manufacturer's specifications. These nettings are usually in rolls 3 to 4 feet wide and up to 300 feet long. C. Peg and twine - Drive 8 to 10 inch wooden pegs to within 2 to 3 inches of the soil surface every 4 feet in all directions. Stakes may be driven before or after applying mulch. Secure mulch to soil surface by stretching twine between pegs in a criss-cross within a square pattern. Secure twine around each peg with two or more round turns. Poles and stakes may also be used to secure brush in place. D. Silt - With a square pointed spade, cut mulch into the surface soil in contour rows 18 inches apart. E. Asphalt mulch tie -down - Asphalt sprayed uniformly on the mulch as it is ejected from the blower is more effective than applied as separate operation. Apply so area has uniform appearance. Rates of application will vary with conditions. The higher the grade number assigned each type of asphalt the higher the percentage of asphalt residue. Asphalt should not be used in freezing weather. (1) Emulsified Asphalt - Apply uniformly 0.04 to 0.08 gallons per square yard or 200 to 400 gallons per acre of rapid setting (RS-1, CRS-I, RS-2, or CRS-2), medium setting (MS -I, MS-2, or CMS-2); slow setting (SS-1 or CSS-1). Rapid setting (RS or CRS) is formulated for curing in less than 24 hours even during periods of high humidity. Best for spring and fall. Medium setting (MS or CMS) is formulated for curing within 24 to 48 hours. Slow setting (SS or CSS) is formulated for use during hot, dry weather with 48 hours or more curing time_ Note - In areas of playing children or pedestrian traffic, asphalt application could cause problems of'Vacldng in" on rugs; damage shoes, clothing, etc. Use types RS or CRS-tominimize problem. F. Mulch can be anchored with rye for fall plantings or millet for summer plantings. Use 1/4 to 1/2 bushel or rye or IS pounds of millet per acre broadcast ahead of mulch application. MAINTENANCE Maintenance is the most important controllable factor in retaining an effective vegetative cover. Control of Competition Competitive weed growth during the period of establishment should be controlled by mowing and/or with herbicides. When chemicals are used, follow current North Carolina Agricultural Experiment Station's chemical weed control recommendations and adhere strictly to instructions on label. 2. Irrigation If soil moisture is deficient, supply new planting with adequate water (3)-4" penetration) for plant growth at 10-day intervals, if needed, until they are established. This -is most important on late season plantings, in abnormally dry or hot seasons. ....... ....... ..._ . ........ __--_-. 4 SEEDING VARIETY During the month of June, July and August a temporary vegetative seeding application will be used due to the season of the year. The seeding recommendation for this time of year is Sudangrass applied at the rate of 35-45 pounds, 1,000 pounds of 10-10-10 fertilizer, and 2,000 pounds of lime per acre. During the months of September, October, and November if there is any remaining areas that have not been stabilized the seeding application of tall fescue' will be applied at the rate of 40-60 pounds, 1,000 pounds of 10-10-10 fertilizer, and 2,000 pounds of lime per acre. The tall fescue shall also be applied to the areas that were seeded in the months of June, July and August.

(1) Emulsified Asphalt - Apply uniformly 0..04 to 0.08 gallons per square yard or 200 to 400 gallons per acre of rapid setting 's:,T.}:r �,M� v-vr..+�....+�...'���.++.-.... �v •..... _..r_ .. _. ... ... ...• ............. ... ...... �_— .. (RS-1, CRS-1, RS-2, or CRS-2), medium setting (MS-1, MS-2, or CMS-2); slow setting (SS-1 or CSS-1). Rapid setting (RS or CRS) is formulated for curing in less than 24 hours even during periods of high humidity. Best for spring and fall. Medium setting (MS or CMS) is formulated for curing within 24 to 48 hours. Slow setting (SS or CSS) is formulated for use during hot, dry weather with 48 hours or more curing time. Note - In areas of playing children or pedestrian traffic, asphalt application could cause problems of "tracking in" on rugs; damage shoes, clothing, etc. Use types RS or CRS to minimize problem. F. Mulch can be anchored with rye for fall plantings or millet for summer plantings. Use 1/4 to I/2 bushel or rye or 15 pounds of millet per acre broadcast ahead of mulch application. MAINTENANCE Maintenance is the most important controllable factor in retaining an effective vegetative cover. Control of Competition Competitive weed growth during the period of establishment should be controlled by mowing.and/or with herbicides. When chemicals are used, follow current North Carolina Agricultural Experiment Station's chemical weed control recommendations and adhere strictly to instructions on label. 2. Irrigation If soil moisture is deficient, supply new planting with adequate water (34" penetration) for plant growth at 10-day intervals, if needed, until they are established_ This is most important on late season plantings, in abnormally dry or hot seasons. SEEDING VARIETY During the month of June, July and August a temporary vegetative seeding application will be used due to the season of the year. The seeding recommendation for this time of year is Sudangrass applied at the rate of 35-45 pounds, 1,000 pounds of 10-10-10 fertilizer, and 2,000 pounds of lime per acre. During the months of September, October, and November if there is any remaining areas that have not been stabilized the seeding application of tall fescue' will be applied at the rate of 40-60 pounds, 1,000 pounds of 10-10-10 fertilizer, and 2,000 pounds of lime per acre. The tall fescue shall also be applied to the areas that were seeded in the months of June, July and August.
