Millbrook Rd. Raleigh, NC 27609 (919)847-8300 www.d-e-inc.com 1 244 W Millbrook Road, Raleigh, NC 27609 Phone: 919-847-8300 P. O. Box 17705, Raleigh, NC 27619 FAX 919-847-2130 Abstract: The site is located on the south side of NC Hwy 24-87 approximately 1 mile south of the intersection of NC Hwy 24 and NC Hwy 87. The site is vacant. The development will consist of 3 separate lots with a total area of 6.48 acres. Lots 2 and 3 will be developed with this submittal. The entire area of lot 2 will be calculated at 80% impervious to allow for future expansion. One half (1.09 ac) of lot 1 will be captured in the BMP. We are using 80% maximum impervious for the portion of lot 1 that will drain to the BMP. The post development for lots 1 (portion), 2 and 3 combined is 67.1 % impervious. The site slopes from north to south. The existing property drains to two different areas. These areas are indicated as drainage area 1 and drainage area 2. Stormwater Management will be required for water quantity and water quality. Stormwater detention will be required to restrict the post - development stormwater discharge to the pre -development rate for the 1-year storm. The detention will be provided within the bioretention pond facility with a restrictor opening in the outlet structure. Note that a separate stormwater BMP will have to be provided for the future use of the post -development 2 area property. The stormwater discharge from the imperious surfaces are being captured and routed through the bioretention pond. There is a small portion of the landscaped area that will bypass the BMP. The bioretention pond will provide for the 85% TSS removal requirement.

There will be a total of 17 cleanouts for the 4" PVC underdrains. The 4" PVC underdrains will be connected to a 6" solid PVC trunk line that will be connected to the riser structure. The following calculation is per section 5.7 of the BMP manual. The follow rate through the soil media is 2" per hour and the safety factor is 10. Q=2"X10=20 D=16(Qxn S 0.5 D=16(20x0.011)=7.04 0.5 Per Table 5-1 of the BMP Manual a minimum of 5 — 4" pipes are required for the bioretention underdrain system. Bio-Retention Draw Down Time Calculations The depth of the water being treated in the bioretention pond is 9". The drainage rate for the soil media is 2" per hour. 9" / 2" = 4.5 hours Bio-Retention Pretreatment This bioretention pond will have 5 different points where the stormwater enters the pond. The stormwater enters the pond via storm pipes with flared end sections. The end of each flared end section will rip rapped with a calculated amount of stone based on the volume and velocity of the stormwater. Once the storm water velocity is dissipated on the rip rap it run onto the grassed portion of bioretention pond. Conclusions The site meets NC DENR Division of Water Quality requirements for peak discharge and 85% TSS reduction.

Page 2 INVESTIGATIVE PROCEDURES Field Investieation UPPATECH E N G I N E E R 5- I N C C�eatechnicat Cngineenng Ewi,,wentat Consulting Constmction Natenets Tesfng The subsurface investigation consisted of nine soil test borings in the proposed construction areas. The test borings were performed in the planned building and pavement areas to depths of 10 to 20 feet below the ground surface. The locations are approximately shown on the Test Boring Plan (Figure 1) included in the Appendix. The test borings were located in the field by our representative by measuring distances and angles from existing site reference points. Ground surface elevations were not known at the time of this report. In general, the locations of the test borings should be considered approximate. Standard penetration testing, as provided for in ASTM D-1586, was performed at selected intervals in the soil test borings. The standard penetration resistance, in conjunction with soil classifications, provides some indication of a soil's engineering characteristics. Detailed descriptions of the soils encountered in the test borings are provided in the Test Boring Records included in the Appendix. Ground water conditions, standard penetration resistances, and other pertinent information are also included. Laboratory Investieation The laboratory investigation consisted of a physical examination and classification of all samples obtained from the drilling operation. Classification of the soil samples was performed in general accordance with ASTM D-2488 (Visual -Manual Procedure for Description of Soils). Soil classifications include the use of the Unified Soil Classification System described in ASTM D-2487 (Classification of Soils for Engineering Purposes). Page 3 GENERAL SITE AND SUBSURFACE CONDITIONS Site Location and Description TRRROTECH ENGINEERS- INC Geatechnical Engineering ErrviranmentaL ConsuLticg CanstmcEan A�atenals 7es:my The subject site is an approximately 6.49 acre tract located southeast of the intersection of NC Highway 24/87 and Plantation Drive in Cameron„ North Carolina The subject parcel is currently undeveloped and partially wooded. Site topography generally slopes away from the center of the site with a slight gradual slope to the southeast. Maximum relief across the site is about 5 to 7 feet. ReEional Geoloev The site is located in the Coastal Plain Geologic Province, just east of the Piedmont Geologic Province. The soils in this area generally consist of marine sediments deposited during successive periods of Fluctuating shoreline. The formations tend to dip slightly seaward, and several are exposed at the surface in bands paralleling the coast. Many beds exist only as fragmented, erosional remnants with more continuous strata located above and below. The soils typically classify as sands, silts, and clays, with irregular deposits of shells. Some of the existing formations contain predominantly plastic clays interbedded with strata of sands and poorly consolidated limestones. Others contain predominantly sands with localized deposits of highly plastic clays. Because the site is located close to the fall line between the Coastal Plain and the Piedmont, the Coastal Plain soils in this area are typically shallow: in the tens of feet. Beneath the Coastal Plain soils, Piedmont soils which are weathered from the underlying rock (residual soils) are typically encountered. The Piedmont soils typically consist of clays and silts in the upper 10 to 30 feet. The soils become coarser grained with depth, and begin to take on the characteristics of the underlying parent rock. When the residual materials have a standard penetration resistance of 100 blows per foot or greater, they are referred to as partially weathered rock. The transition from soil to partially weathered rock is usually a gradual one, and may occur at a wide range of depths. Lenses or layers of partially weathered rock are not unusual in the soil profile. Partially weathered rock represents the zone of transition between the soil and the underlying rocks from which the soils are derived. The thickness of the zone of partially weathered rock and the depth to the rock surface have both been found to vary considerably over relatively short distances. The depth to the rock surface in the area has generally been found to range from about 10 to 60 feet below the ground surface. General Subsurface Conditions A surficial layer of topsoil was encountered in test boring B-4 to an approximate depth of 1 inch. The thickness of topsoil can be quite variable and could be significantly different at other locations on the site. The reported topsoil thicknesses should not, therefore, be used for detailed quantity estimates. Beneath the topsoil in test boring B-4 and from the ground surface in the remaining borings, soils _ typical of the Coastal Plain were encountered. These soils typically consisted of sands, slightly clayey sands, slightly silty sands, and clayey sands. Standard penetration resistances in these soils generally ranged from 2 to 18 blows per foot.

It should be noted that ground water levels will fluctuate depending on seasonal variations of precipitation and other factors, and may occur at different elevations at some time in the future.

Page 5 PROPOSED CONSTRUCTION TFRPOTECH E N G I N E E 3 S- I N C C,eotechnlcal Cngineenng E.nw,n,,ntaL Consulting Conatmction Materiate Tniing Our understanding of the proposed construction is based on our e-mail correspondence with Mr. Bob Brantley. We understand that the planned construction will consist of two single story buildings with metal stud and wood frame construction and a concrete slab -on -grade floor system. The Bojangles' building will most likely have a brick veneer. In front of the convenience store will be an overhead canopy for the gas pump islands and a subsurface tank farm. A bio-retention pond is planned on the south side of the site. Asphalt and Portland cement concrete driveways and parking areas are planned around each of the buildings. Structural loading conditions are not currently known. However, based on our experience with similar construction we have estimated a maximum wall load of 3 kips per lineal foot. The canopy footings are expected to be designed with uplift loads governing their size. Site grading plans are expected to include cut and fill placement of approximately 3 to 5 feet. Pavements are expected to be bituminous concrete or Portland cement concrete. Based on the parking lot size and planned building use, we have estimated traffic volumes of 1000 cars per day, 5 tractor -trailer trucks per day including fuel delivery trucks, 10 delivery trucks per week, and one dumpster truck per week. If actual traffic volumes are greater than these assumed maximums, please contact us and we will review our recommendations for applicability to the actual traffic volumes. TRRP4TECH E N G I N E E R S- I N C CeotechrucaL Lngineering CMtrmmentaL Consultiny Page 6 Cons<ructian MatenaLs Testing EVALUATIONS AND RECOMMENDATIONS The following recommendations are based on the information available on the proposed structures, the data obtained from our soil test borings, and our experience with soils and subsurface conditions similar to those encountered at this site. Because the test borings represent a very small statistical sampling of subsurface conditions, it is possible that conditions may be encountered during construction that are substantially different from those indicated by the test borings. In these instances, adjustments to the design and construction may be necessary depending on actual conditions. General Site Development Considerations Based on the results of our test borings, very loose to loose sands were encountered in all of our test boring locations. Remedial measures during building and pavement construction should be expected. Based on the results of our analysis, the planned construction can be supported on shallow foundations designed using an allowable bearing pressure of 1,500 pounds per square foot. Based on our assumed loading conditions, the estimated post -construction foundation settlement related to the application of building loads is expected to be approximately 0.50 inch to 0.75 inch, if the recommended foundation bearing pressure is used. General Site Preparation All underbrush, topsoil, roots, and other deleterious materials should be removed from the proposed construction area. Special attention should be given to the removal of tree stumps within the proposed construction area. Site clearing, grubbing, and stripping should be performed only during dry weather conditions. Operation of heavy equipment on the site during wet conditions could result in excessive mixing of topsoil, and organic debris with clean underlying soils. The majority of our test borings encountered very loose to loose sands near the ground surface. After removal of the topsoil, we (recommend that these soils be compacted to a minimum of 95% of their standard Proctor maximum dry density utilizing large vibratory compaction equipment. Adequate density tests should be performed to verify that the recommended level of compaction is achieved. Some moisture conditioning of the near surface soils will likely be required to facilitate compaction. The intent of the compaction operations recommended for the surficial soils is two -fold. One is to provide a stable base for operation of construction equipment and construction of the planned buildings. The second is to reduce the potential for settlement of the foundations and Floor slabs. While the compaction of the near surface soils from the ground surface will reduce the long-term settlement potential, our test borings revealed that the depth of the loose sands is at least 20 feet below the existing ground surface. The recommended compaction operations at the ground surface will not densify the soils to this depth. After the near surface sands have been adequately compacted, we recommend that proofrolling operations be performed.. We recommend that areas to receive structural fill be proofrolled prior to placement of structural fill. Areas of proposed excavation should be proofrolled after rough finished subgrade is achieved. Proofrolling should be performed using a loaded dump truck weighing at least 15 tons. Proofrolling should be accomplished by performing at least 3 passes in each of two perpendicular directions within entire construction areas, and 10 feet beyond. Any unsuitable materials Page 7 TRRpaTECH E N G I N E E R S- I N C C,eatechnicaL Engineering LnvironmentaL Consulting Construction MatenaLs Tesfing that may be present, and any low consistency soils that are encountered which cannot be adequately densified in place, should be removed and replaced with well compacted fill material placed in accordance with the Structural Fill section of this report. Proofrolling should be observed by our representative to determine if remedial measures are necessary. Proofrolling should facilitate the identification of soft surficial soils, but should not be expected to reveal soft conditions more than 2 feet below the ground surface at the time of proofrolling. Footing examinations will be required to evaluate the presence of deeper soft soils, which could adversely affect foundation support. Footing examinations will be discussed later in this report. We understand that a bio-retention pond will be constructed at the south side of the site. The encountered soils at the site have a high rate of infiltration and a high permeability. If the pond is planned to hold water, it would be necessary to line the pond with a low permeability material. Based on our experience on similar sites, there may also be buried foundations, bum pits or trash pits. On sites located near developed areas this is not an unusual occurrence. All too frequently such buried material occurs in isolated areas which are not detected by the soil test borings. Any buried waste construction debris or trash which is found during the construction operation should be thoroughly excavated, and the waste material should be removed from the site prior to placement of fill soils or building construction. Earth Slopes Temporary construction slopes should be designed in strict compliance with the most recent OSHA regulations. The test borings indicate that most soils at the site are either Type B or Type C as defined _ in the OSHA regulations. This dictates that temporary construction slopes be no steeper than 1.5 horizontal to 1 vertical (Type C soils) for excavation depths of up to 20 feet. Flatter slopes may be needed depending upon conditions at the time of construction. The use of well points and the sandy nature of the soils at the site will affect the stability of deeper excavations. A "competent person", as defined by OSHA regulations, should be present on site during excavation. Depending upon conditions encountered, some excavations may require shoring. Temporary construction slopes should be closely observed for signs of mass movement: tension cracks near the crest, bulging at the toe of the slope, etc. If potential stability problems are observed, the geotechnical engineer should be immediately contacted. The responsibility for excavation safety and stability of construction slopes should lie solely with the contractor. We recommend that permanent cut or fill slopes be no steeper than 3.0 (H) to 1.0 (V) to maintain long term stability. Slopes constructed steeper than 3.0 (H) to 1.0 (V) could be highly susceptible to erosion, will be difficult to maintain, and could experience large scale slope failure in some instances. Flatter slopes may be necessary, depending upon the type of erosion control selected. We recommend that buildings be located at least 15 feet from the crest of adjacent slopes. Pavement areas should be located at least 5 feet away from the crest of adjacent slopes. Page 8 Groundwater Control UPPATECH E N G I N E E R 5- I N C <,eote6,w.L C.ngmering' [mironmenbL Con utting Canst,u,twn Mi teri.b Tasting _ Based on the conditions encountered in our borings, the depth to groundwater generally exceeds our boring depths. Therefore, we do not anticipate that excavation at the site will encounter groundwater. If ground water is encountered, the most suitable method of controlling this water will likely be pumping directly from the excavation. Pumping from excavations should be done with care to prevent loss of soil fines, boils, or instability of slopes. If pumping proves to be ineffective, then the use of well points or other methods may be required. We must emphasize that the need for ground water control and the most appropriate method will be based on the conditions encountered during construction. The contractor should use the most effective dewatering method based on the conditions at that time. Foundation Design _ After site preparation and site grading are complete, it is our opinion that the proposed structures may be supported on conventional shallow foundations. We recommend that footings for the building be designed for an allowable bearing pressure of 1,500 pounds per square foot (psf). In addition, we recommend a minimum width of 18 inches for continuous wall footings and 24 inches for isolated column footings to prevent localized shear failure. Footings should bear at a minimum depth of 18 inches below the prevailing exterior ground surface elevation to avoid potential problems due to frost heave. The footings for the fuel canopies will likely bear at an elevation of 5 to 8 feet below the ground surface to resist uplift loads. Based on the results of our test borings in the area of the planned fuel canopies, the foundation bearing materials at these depths are expected to consist of sands and slightly clayey sands generally capable of supporting a design bearing pressure of 1,500 pounds per square foot. Although our test borings did not encounter any ground water, if ground water is encountered during footing excavations, the footing size may be required to be increased due to additional uplift forces caused by ground water. Detailed footing examinations should be performed in each footing excavation prior to placement of reinforcing steel. These examinations should be performed by our representative to confirm that the design allowable soil bearing pressure is available. The footing examinations should be performed using a combination of visual observation, hand rod probing, and dynamic cone penetrometer testing. Dynamic cone penetrometer testing, as described in ASTM STP-399, should be performed in each column footing location and at no greater than 20 foot intervals in continuous wall footings. If the soil is found to have an unsatisfactory bearing capacity, our inspector will review the problem with our project Geotechnical Engineer. Recommendations will be developed to be immediately implemented in order to minimize construction delays. Very loose to loose sands were encountered near the ground surface in the majority of our test borings. Depending on the final design bearing elevations of the foundations, remedial measures may be required to achieve the design foundation bearing pressure. The most feasible remedial measure in most cases is stone replacement, where any encountered soft, wet soils are removed from the footing excavations and replaced with washed 457 stone. The washed #57 stone should be placed in maximum lifts of 12 to 18 inches, and each lift should be consolidated with a vibratory plate tamp or similar seq apeu8gns aql leg!

If soft areas are encountered, recommendations for remedial measures should be provided by our project geotechnical engineer. Pavement Desien Recommendations Based on the above described site preparation recommendations, we anticipate that the pavement area subgrade soils will generally consist of sands and slightly clayey sands. These materials may reasonably have a California Bearing Ratio (CBR) ranging from approximately 10 to 20, if compacted to at least 100% of the standard Proctor maximum dry density. For purposes of pavement design, we have used a California Bearing Ratio of 10 for the pavement subgrade soils and the loading condition described previously in this report. Based on the AASHTO design method, a 20 year design life, and our past experience, we suggest the following design pavement section: Parking Areas: 2 inches Bituminous Concrete Surface Course 6 inches Aggregate Base Course Driveways: 3 inches Bituminous Concrete Surface Course 8 inches Aggregate Base Course Preparing, grading, shaping, and compaction of subgrade soils should be performed in accordance with Division 5, section 501 of the NCDOT Standard Specifications for Roads and Structures (2006). Preparing, grading, shaping, and compaction of aggregate base course (ABC) stone should be _ performed in accordance with Division 5, section 520 of the NCDOT Standard Specifications for Roads and Structures (2006). Placement and compaction of the bituminous concrete surface course (Type SF9.5A) should be performed in accordance with Division 6, section 600 of the NCDOT Standard Specifications for Roads and Structures (2006). Proper subgrade compaction, adherence to the NCDOT specifications, and compliance with project plans and specifications are critical to the performance of the constructed pavement. The recommended pavement section is designed to support the traffic volumes expected after completion of the planned construction. If construction traffic is allowed to use the recommended pavement section, some damage requiring repair should be expected. Based on our past experience, we recommend that a Portland cement concrete pavement be used in dumpster areas, in areas where fuel delivery tracks will operate, and in other areas where heavy trucks are turning while traveling at slow speeds. We suggest the use of a 6 inch thick section ofNCDOT type AA Portland cement concrete having a 28 day design compressive strength of 4,500 psi above a 6 inch thick section of compacted ABC stone. The concrete pavement may be designed as a "plain concrete pavement" with no reinforcing steel, or reinforcing steel may be used at joints. Construction joints and _ other design details should be in accordance with guidelines provided by the Portland Cement Association and the American Concrete Institute. The rigid pavement system should be constructed in accordance with section 700 of the NCDOT Standard Specifications.

Routine adjustment of moisture content will be necessary to allow compaction in accordance with project specifications. Structural Fill In order to achieve high density structural fill, the following recommendations are offered: (1) Materials selected for use as structural fill should be free of vegetable matter, waste construction debris, and other deleterious materials. The material should not contain rocks having a diameter over 3 inches. It is our opinion that the following soils represented by their USCS group symbols will typically be suitable for use as structural fill: (SP), (SW), (SP-SC), (SP-SM), (ML), (CL), (SM), and (SC). The following soil types are considered unsuitable: (MH), (CH), (OL), (OH), and (Pt). (2) Laboratory Proctor compaction tests and classification tests should be performed on representative samples obtained from the proposed borrow material to provide data necessary to determine acceptability and for quality control. The moisture content of suitable borrow soils should generally not be more than 3 percentage points above or more than 3 percentage points below optimum at the time of compaction. Tighter moisture limits may be necessary with certain soils. (3) Suitable fill material should be placed in thin lifts (lift thickness depends on type of compaction equipment, but in general, lifts of 8 inches loose measurement are recommended). The soil should be compacted by mechanical means such as sheepsfoot rollers or vibratory drum. Proofrolling with rubber tired, heavily loaded vehicles may be desirable at approximately every third lift to bind the lifts together and to seal the surface of the compacted area thus reducing potential for absorption of surface water following a rain. This sealing operation is particularly important at the end of the work day and at the end of the week. (4) We recommend that structural fill be compacted to a minimum of 95% of the standard Proctor maximum dry density (ASTM Specification D-698). Additionally, the in -place maximum dry density of structural fill should be no less than 90 pcf. The upper 12 inches of floor slab subgrades should be compacted to at least 98% of the standard Proctor maximum dry density (ASTM D-698). Fill placement in pavement areas should be performed in accordance with the NCDOT Standard Specifications. (5) . An experienced soil engineering technician should take adequate density tests throughout the fill placement operation to verify that the specified compaction is achieved. It is particularly important that this be accomplished during the initial stages of the compaction operation to enable adjustments to the compaction operation, if necessary.

Pro f e s s i o n o/ E n g i n e e r i n g C o n s u/ t O n t s October 12, 2010 NC Dept of Environment & Natural Resources Division of Water Quality 512 N Salisbury Street Raleigh, NC RE: Narrative describing the stormwater treatment and management for the project Bojangles I Convenience Store — NC 24.87 Cameron, NC - Harnett County To Whom It May Concern: This is a 6.48 acre commercial project on the west side of NC 24-87 just north of the intersection of Plantation Drive (SR 2411). The project consists of three (3) separate lots that front on NC 24-87. A 17,000 SF bioretention pond is being utilized the treat the stormwater runoff from the 3 lots. The bioretention pond is providing for the 85% removal of the Total Suspended Solids. Each individual lot has an allocated amount of impervious area. Lot 1 is a split drainage site. It drains to two different drainage basins. 50% of the property area of lot 1 will drain to the bioretention pond, a maximum 80% impervious has been assumed for the portion of lot 1 that drains to the bioretention pond. All of lots 2 and 3 drain to the bioretention pond. Drainage easements are provided across the each property for the collection and routing of the stormwater to the bioretention pond. A storm drainage yard inlet within the bioretention structure will serve as the storm drainage outlet structure. There will be a stormwater management agreement in place for the ongoing maintenance of the bioretention pond. The bioretention pond will also provide detention for the peak post development discharge for the 1-year storm. A 19" wide x 2 5/8" height restrictor opening will be provided on all four (4) sides of the storm drainage yard inlet to restrict the stormwater discharge to the post development rate.
