Geotechnical Engineering Analysis Lot 3 BRM Associates #1, LLC Wilmington, New Hanover County, North Carolina ECS Project No 22 18078 Dear Mr Cockrum As requested, ECS met with Vincent Lewis of NCDENR to confirm the results of the seasonal high water level estimation On February 12, 2013, two hand auger borings were performed on the site The purpose of the hand auger borings was to stratify the subsurface sods and estimate the seasonal high water table We evaluated the subsurface soil conditions by drilling the hand auger bonngs to depths ranging from approximately 48 inches below the existing ground surface at the approximate locations indicated on the attached sketch At that depth, NCDENR confirmed our seasonal high water table estimation of 48 inches In the hand auger bonngs, redoximorphic deplebons and concentrations of iron, known as "drainage mottles", are used as soil indicators to estimate the seasonal high water table These soil indicator features can form in a matter of days in ideal conditions and remain unchanged for decades or more after the water table has changed We appreciate the opportunity to be of service to you during the design phase of this project and look forward to our continued involvement during the construction phase If you have any questions concerning the information and recommendations presented in this report, please contact us

development peak discharge to be less than the pre -development discharge for the 2-, 10- and 24- year storm events See Section 1 - Table 1 for the summary of the peak discharges for the site H THOMAS & HUTTON Z \24079\24079 0001\Documents\Reports\24079 0001 Stormwater Management Report doc Page 2 Taco Bell —South Monkey Junction Stormwater Management Report and Erosion Control Design Considerations BMP's will be used and maintained throughout the construction of the project to minimize sediment and erosion control Sediment control devices will consist of temporary silt fencing, inlet protection, grassing, and np rap stabilization at outlets and areas of concentrated flows All sediment and erosion control devices will be in -place prior to construction and/or constructed as necessary The project engineer and/or designated agents for the owner will monitor all sediment and erosion control devices during construction The sediment and erosion devices will be removed after permanent stabilization of the site has been accomplished The anticipated construction sequence is as follows t Install gravel construction entrance/exit, silt fence and tree protection 2 Clearing and grubbing 3 Install remaining drainage conveyances and erosion control 4 Site rough grading and infrastructure 5 Install curbs and stone base for paving 6 Budding Construction 7 Sidewalks and paving 8 Final grassing and stabilization 9 Restore drainage conveyances to design specifications, remove temporary erosion control measures once site is permanently stabilized H THOMAS & HUTTON Z \24079\24079 0001 \Documents\Reports\24079 0001 Stormwater Management Report doe Page 3 Taco Bell -

18078 1 0 EXECUTIVE SUMMARY This report contains the results of our subsurface exploration and geotechnical engineering analysis for the proposed site located at 5972 Carolina Beach Road in Wilmington, North Carolina The proposed site Is approximately 0 91 acres At the time of our field exploration, the site was open and relatively level with typical elevations ranging from 40 to 45 feet We understand that a one-story, approximately 2,900 square foot restaurant will be constructed on the proposed site Protect specific information including structural and grading information was not available at the time this report was prepared Approximately 2 to 6 inches of organic topsoil was reported by the drillers at the CPT sounding locations Beneath the surface to depths of about 7 feet, the test soundings typically encountered intermittent layers of loose to medium dense silty, slightly silty and clean sands (SM, SP-SM, SP) and firm to stiff sandy silts (ML) From 7 feet to depths of approximately 10 feet, the test soundings typically encountered intermittent layers of soft to firm sandy silts and clayey silts (ML, ML-CL) From 10 feet to depths of approximately 20 feet, the test soundings typically encountered intermittent layers of medium dense to very dense silty, slightly silty and clean sands (SM, SP-SM, SP) and firm sandy silts (ML) It is important to note that the near surface site soils consist of relatively loose sands These soils will likely require in -place densification to achieve a stable subgrade for support of the proposed construction In summary, the proposed buildings can be supported on conventional shallow foundations For foundations designed and constructed in accordance with the recommendations provided In this report, a net allowable soil bearing pressures of 3,000 pounds per square foot (psf) is recommended for use in proportioning shallow foundations bearing at least 12 inches below the prevailing grades Once structural loads and protect grading layouts are determined, we request that they be provided to us so that we may review our recommendations and make any necessary changes Specific information regarding the subsurface exploration procedures used, the site and subsurface conditions at the time of our exploration, and our conclusions and recommendations concerning the geotechnical design and construction aspects of the protect are discussed in detail in the subsequent sections of this report Please note this Executive Summary is an important part of this report and should be considered a "summary" only The

OVERVIEW 2 1 Project Information Our understanding of the proposed construction is based upon our discussions with representatives of Environments Unlimited The proposed site is located at 5972 Carolina Beach Road in Wilmington, North Carolina The proposed site is approximately 0 91 acres At the time of our field exploration, the site was covered with open and relatively level with typical elevations ranging from 40 to 45 feet We understand that a one-story, approximately 2,900 square foot restaurant will be constructed on the proposed site Project specific Information Including structural and grading Information was not available at the time this report was prepared 2 2 Scope of Work The conclusions and recommendations contained in this report are based on the results of the following • two electronic cone penetration test (CPT) test sounding • one direct push sampling boring • two hand auger borings and Infiltration tests • engineering analyses of the field findings with respect to the provided project Information 2 3 Purposes of Exploration The purpose of this exploration program was to determine the soil and groundwater conditions at the site and to develop engineering recommendations to assist in the design and construction of the proposed project We accomplished these objectives as follows • performing a site reconnaissance to evaluate the existing site conditions • performing soundings and borings to explore the subsurface soil and groundwater conditions performing hand auger borings to estimate seasonal high groundwater level, • performing infiltration tests to determine the infiltration rate of the soils in the proposed stormwater BMP, • analyzing the field to develop appropriate geotechnical engineering design and construction

EXPLORATION PROCEDURES 3 1 Subsurface Exploration Procedures 3 1 1 Cone Penetration Testing Two electronic cone penetration test soundings were performed in the proposed building area during our field exploration The cone penetration test soundings were performed in general conformance with ASTM D 5778 by our subcontractor The soundings were advanced to depths of 20 feet The soundings were performed with a track mounted rig The approximate location of the CPT sounding is indicated on the Exploration Location Map in Appendix A of this report The cone used in the sounding has a tip area of 10 cmZ and a sleeve area of 150 cmZ The CPT soundings recorded tip resistance and sleeve friction measurements to assist in determining pertinent index and engineering properties of the site soils The ratio of the sleeve friction to tip resistance is then used to aid in assessing the soil types through which the tip is advanced The results of the CPT are presented in Appendix B In addition to the CPT soundings, one direct push boring was performed in the proposed BMP area The direct push obtains continuous soil samples by driving four foot long sample tubes by means of a percussion hammer The sample tubes are returned to the soils laboratory in Wilmington, North Carolina The samples are visually classified and used to help verify the soil descriptions in the nearby CPT sounding 3 1 2 Hand Auger Borings and Infiltration Tests On September 5, 2012, two hand auger borings were performed on the site The purpose of the hand auger borings was to stratify the subsurface soils and estimate the seasonal high water table We evaluated the subsurface soil and ground water conditions by drilling the hand auger borings to depths ranging from approximately 70 to 80 inches below the existing ground surface at the approximate locations indicated on the Exploration Location Diagram in Appendix A of this report We visually classified the subsurface soils on site The results are provided in Section 4 5 and in Appendix C In the hand auger borings, redoximorphic depletions and concentrations of iron, known as "drainage mottles", are used as soil indicators to estimate the seasonal high water table These soil indicator features can form in a matter of days in ideal conditions and remain unchanged for decades or more after the water table has changed Report of Subsurface Exploration and Geotechnical Engineering Evaluation Lot 3 BRM Associates #1 LLC Wilmington, New Hanover County, North Carolina ECS Protect No 22 18078 4 0 EXPLORATION RESULTS 4 1 Site Conditions The proposed site is approximately 0 91 acres At the time of our field exploration, the site was covered with open and relatively level with typical elevations ranging from 40 to 45 feet 4 2 Regional Geology The site is located in the Coastal Plain Physiographic Province of North Carolina The Coastal Plain is composed of seven terraces, each representing a former level of the Atlantic Ocean Soils in this area generally consist of sedimentary materials transported from other areas by the ocean or rivers These deposits vary in thickness from a thin veneer along the western edge of the region to more than 10,000 feet near the coast The sedimentary deposits of the Coastal Plain rest upon consolidated rocks similar to those underlying the Piedmont and Mountain Physiographic Provinces In general, shallow unconfined groundwater movement within the overlying soils is largely controlled by topographic gradients Recharge occurs primarily by infiltration along higher elevations and typically discharges into streams or other surface water bodies The elevation of the shallow water table is transient and can vary greatly with seasonal fluctuations in precipitation 4 3 Soil Conditions CPT Soundings Approximately 2 to 6 inches of organic topsoil was reported by the drillers at the CPT sounding locations Beneath the surface to depths of about 7 feet, the test soundings typically encountered intermittent layers of loose to medium dense silty, slightly silty and clean sands (SM, SP-SM, SP) and firm to stiff sandy silts (ML) The equivalent corrected standard penetration test resistances (N'-values) in these soils generally ranged from 5 to 26 blows per foot (bpf) From 7 feet to depths of approximately 9 feet, the test soundings typically encountered intermittent layers of soft to firm sandy silts and clayey silts (ML, ML-CL) The equivalent corrected standard penetration test resistances (N'-values) in these soils generally ranged from 4 to 10 bpf From 9 feet to depths of approximately 20 feet, the test soundings typically encountered intermittent layers of medium dense to very dense silty, slightly silty and clean sands (SM, SP- SM, SP) and stiff sandy silts (ML) The equivalent corrected standard penetration test resistances (N`-values) in these soils generally ranged from 9 to 53 bpf The descriptions provided in this section are a general summary of the subsurface conditions encountered within the CPT test soundings The CPT Sounding Records in Appendix B contain detailed information recorded at each of the sounding locations Direct Push Boring From the surface to 8 feet, the direct push boring typically encountered intermittent layers of light gray, tan, dark brown and brown, silty and clean sands (SM, SP) Report of Subsurface Exploration and Geotechnical Engineering Evaluation Lot 3 BRM Associates #1, LLC Wilmington, New Hanover County, North Carolina ECS Project No 22 18078 4 4 Groundwater Conditions Porewater pressure measurements were made at all sounding locations during exploration Furthermore, visual observations of the samples retrieved during drilling exploration were also used in evaluating the groundwater conditions The groundwater depths were observed to range from about 6 3 to 7 9 feet below the existing grade in the CPT soundings In the Direct push boring, the groundwater was observed to be at approximately 7 0 feet The highest groundwater observations are normally encountered in the late winter and early spring Variations in the location of the long-term water table may occur as a result of changes in precipitation, evaporation, surface water runoff, and other factors not immediately apparent at the time of this exploration If long term water levels are crucial to the development of this site, it would be prudent to verify water levels with the use of perforated pipes or piezometers 4 5 Seasonal High Water Table and Infiltration Test Results The results from

in this report are based upon our understanding of the proposed construction, the information provided to us during this study and our past experience with similar conditions Should any of the Information provided to us be changed prior to final design, ECS should be notified to review these recommendations and make appropriate revisions, if necessary 5 1 Subgrade Preparation The first step in preparing the site for the proposed construction should be to remove vegetation, rootmat, topsoil, deleterious materials, existing pavement, foundations, utilities, and any other soft or poor materials from the existing ground surface These operations should extend at least 10 feet, where possible, beyond the planned limits of the proposed buildings and pavements After proper clearing, stripping, grubbing, and prior to fill placement, foundation, slab, or pavement construction, the exposed subgrade soils should be carefully evaluated by an experienced geotechnical engineer to Identify any localized unsound or otherwise poor materials After evaluating the exposed soils, proofrolling using a smooth drum roller; having an axle weight of at least 10 tons, is suggested to be used at this time to aid In Identifying localized loose and yielding areas which should be removed The proofrolling will also help density the upper exposed subgrade soils During this process, it may be necessary to allow groundwater brought to the surface during densification to recede prior to continued densification or subsequent fill placement Any soft or substandard materials identified during proofrolling operations should be either repaired in -place or removed and replaced with an approved backflll placed and compacted in accordance with recommendations of this report Site subgrade conditions will be significantly influenced by weather conditions Subgrades that are evaluated after periods of rainfall will not respond as well to proofrolling as subgrades that are evaluated after periods of more favorable weather We strongly recommend that rubber tire equipment not be used if subgrade conditions exhibit elevated moisture conditions The contractor should use tracked equipment to minimize the degradation of marginally steady subgrade The preparation of fill subgrades, as well as proposed building subgrades, should be observed on a full-time basis by ECS personnel These observations should be performed by an experienced geotechnical engineer or qualified person to ensure that substandard materials have been removed and that the prepared subgrade meets project requirements for support of the proposed construction and/or fills Report of Subsurface Exploration and Geotechnical Engineering Evaluation Lot 3 BRM Associates #1 LLC Wilmington New Hanover County North Carolina ECS Project No 22 18078 5 2 Enafneered Fill Placement Following the removal of deleterious surface and subsurface materials, and after achieving a stable subgrade, engineered fills can be placed and compacted to achieve the desired site grades Fill for support of the proposed construction and for backfill of utility Imes within expanded building and pavement limits should consist of an approved material, free of organic matter and debris and cobbles greater than 3 Inches, and have a Liquid Limit (LL) and Plasticity Index (PI) less than 35 and 9, respectively We also recommend that fills within structural areas have a standard Proctor (ASTM D 698) maximum dry density of at least 100 pounds per cubic foot (pcf) Materials that should not be used as engineered fill Include topsoil, organic materials (OH, OL), and high plasticity clays and silts (CH, MH) Such materials removed during grading operations should be either stockpiled for later use in landscape fills, or placed in approved on or off -site disposal areas Existing soils containing significant amounts of organic matter will not be adequate for re -use as engineered fill As such, the organic content of the near surface soils should be evaluated to determine if some of these soils will be adequate for re -use as engineered fill Natural fine- grained soils classified as clays or silts (CL, ML) with LL and PI greater than 35 and 9, respectively, should be evaluated by the geotechnlcal engineer at the time of construction to determine their suitability for use as engineered fill Prior to the commencement of fill operations and/or utilization of any off -site borrow materials, the contractor should provide representative samples of the proposed fill soils to the geotechnlcal engineer The geotechnlcal engineer can determine the material's suitability for use as an engineered fill and develop moisture -density relationships in accordance with the recommendations provided herein Samples should be provided to the geotechnlcal engineer at least 3 to 5 days prior to their use in the field to allow for the appropriate laboratory testing to be performed FIII materials placed within the building and pavement areas should be placed in lifts not exceeding 8 inches in loose lift thickness and moisture conditioned to within their working range of optimum moisture content The fills should then be compacted to a minimum of 98 percent of the soil s standard Proctor (ASTM D 698) maximum dry density The typical working range of optimum moisture for the natural Coastal Plain soils at the site is expected to be within approximately 3 percent of the optimum moisture content Care should also be taken to provide a smooth, gently sloping ground surface at the end of each day's earthwork activities to help reduce the potential for ponding and absorption of surface water Grade controls should also be maintained throughout the filling operations Filling operations should be observed on a full-time basis by qualified ECS personnel to determine that the required degrees of compaction are being achieved We recommend that a minimum of one compaction test per 2,000-square-foot area be performed for each lift of controlled fill The elevation and location of the tests should be clearly identified at the time of fill placement Areas which fail to achieve the required degree of compaction should be re -worked until the specified degree of compaction is achieved Failing test areas may require moisture adjustments or other remedial activities in order to achieve the required compaction Report of Subsurface Exploration and Geotechnical Engineering Evaluation Lot 3 BRIM Associates #1, LLC Wilmington, New Hanover County North Carolina ECS Protect No 22 18078 Fill materials should not be placed on frozen, frost -heaved, and/or soils which have been recently subjected to precipitation Wet or frozen soils should be removed prior to the continuation of site grading and fill placement Borrow fill materials, if required, should not contain excessively wet or frozen materials at the time of placement Additionally, if grading operations occur during the winter months, frost -heaved soils should be removed prior to placement of engineered fill, granular sub -base materials, foundation or slab concrete, and asphalt pavement materials If problems are encountered during the site grading operations, or if the actual site conditions differ from those encountered during our subsurface exploration, the geotechnical engineer should be notified Immediately 5 3 Foundations Recommendations Provided the subgrade preparation and earthwork operations are completed in strict accordance with the recommendations of this report, the proposed support structures can be supported on conventional shallow foundations bearing on approved natural materials and/or properly compacted fill We recommended a net allowable design soil bearing pressure of 3,000 psf for proportioning continuous and Isolated column footings To reduce the possibility of foundation bearing failure and excessive settlement due to local shear or "punching" failures, we recommend that continuous footings have a minimum width of 18 Inches and that Isolated column footings have a minimum lateral dimension of 30 Inches Furthermore, footings should bear at a depth to provide adequate frost cover protection For this region, we recommend the bearing elevation be a minimum depth of 12 Inches below the finished exterior grade or in accordance with the local building code requirements Once structural loads and site grades are established, we request that they be provided to us to review our recommendations and make any necessary changes The net allowable soil bearing pressure refers to that pressure which may be transmitted to the foundation bearing soils in excess of the final minimum surrounding overburden pressure The final footing elevation should be evaluated by ECS personnel to verify that the bearing soils are capable of supporting the recommended net allowable bearing pressure and are adequate for foundation construction This analysis should Include visual observations, hand rod probing, and dynamic cone penetrometer (ASTM STP 399) testing, or other methods deemed appropriate by the geotechnical engineer at the time of construction, in each column footing excavation and at intervals not greater than 20 feet in continuous footing excavations The settlement of a structure is a function of the compressibility of the bearing materials, bearing pressure, actual structural loads, fill depths, and the bearing elevation of footings with respect to the final ground surface elevation Estimates of settlement for foundations bearing on engineered or non -engineered fills are strongly dependent on the quality of fill placed Factors which may affect the quality of fill include maximum loose lift thickness of the fills placed and the amount of compactive effort placed on each lift Provided that the recommendations outlined in this report are strictly adhered to, we expect that total settlements for the proposed construction are expected to be in the range of 1 inch or less, while the differential settlement will be approximately 1/2 of the anticipated total settlement This Analysis is based on our engineering experience and assumed structural loadings for this type of structure, and is intended to aid the structural engineer with his design Report of Subsurface Exploration and Geotechnical Engineering Evaluation Lot 3 BRM Associates k1 LLC Wilmington New Hanover County, North Carolina ECS Project No 22 18078 Exposure to the environment may weaken the soils at the foundation bearing elevation if the foundation excavations remain exposed during periods of Inclement weather Therefore, foundation concrete should be placed the same day that proper excavation is achieved and the design bearing pressure verified If the bearing soils area softened by surface water absorption or exposure to the environment, the softened soils must be removed from the foundation excavation bottom Immediately prior to placement of concrete If the excavation must remain open overnight, or if Inclement weather becomes Imminent while the bearing soils are exposed, we recommend that a 2 to 3 Inch thick "mud -mat' of "lean' concrete be placed over the exposed bearing soils before the placement of reinforcing steel 5 4 Floor Slab Design Provide a suitable subgrade will be prepared as recommended herein, ground level slabs can be designed as slabs -on -grade Our findings Indicate that a modulus of subgrade reaction (ks) of 150 pci is appropriate for design provided that upper 12 Inches of the slab subgrade soils have been uniformly compacted to at least 98 percent of their standard Proctor maximum dry density and are unyielding during proofrolling We recommend that slabs -on -grade be Isolated from the foundations so that potential differential settlement of the structure will not Induce shear stresses in the floor slab Also, to minimize the crack width of any shrinkage cracks that may develop near the surface of the slab, wire mesh reinforcement may be included in the slab design The mesh should be located in the top third of the slab to be effective We also recommend that slabs -on -grade be underlain by a minimum of 6 Inches of open graded aggregate to help prevent the capillary rise of subsurface moisture from adversely affecting the slab If open graded aggregate is not available, clean sand with less than 3 percent fines can be used provided the placement and compaction of the sand complies with the above recommendations If floor covering such as the or carpet will be utilized for Interior finishes, a polyethylene vapor barrier may be used beneath the floor slab for moisture control considerations 5 5 Lateral Earth Pressures Any below -grade or retaining walls utilized for this project should be designed to withstand the lateral earth pressures and hydrostatic pressure exerted upon them In the design of below - grade retaining walls to restrain compacted sandy engineered fill or sandy in -situ natural soils, the following soil parameters can be utilized • Internal friction angle of 330 • Saturated unit weight of 115 pcf • At -Rest State, earth pressure coefficient (Ko) of 0 45 for the sands • Active State, earth pressure coefficient (Ka) of 0 29 for the sands • Passive State, earth pressure coefficient (Kp) of 3 39 for the sands • Friction factor, f = 0 35 Report of Subsurface Exploration and Geotechnical Engineering Evaluation Lot 3 BRM Associates #1 LLC Wilmington, New Hanover County, North Carolina ECS Protect No 22 18078 For wall conditions where wall movement cannot be tolerated or where the wall Is restrained at the top, the "At Rest' earth pressure should be used For wall conditions where outward wall movement in the range of 1/2 to 1 percent of the wall height can be tolerated, the "Active" earth pressure should be used In evaluating the resistance of soil to lateral loads Imposed by structures, the "Passive" earth pressure should be used Please note that the full development of passive pressure requires deflections toward the soil mass on the order of 1 to 4 percent of the wall height Furthermore, the passive contribution within the zone of frost penetration (12 Inches) should be neglected The type of retaining wall used should be carefully selected considering adjacent areas and construction Irrespective of the retaining wall system chosen, we recommend that the design of the new retaining walls consider their global stability We recommend that the global factor of safety should be at least 1 5 Other factors of safety shall be as follows Factor of Safety against Sliding > 1 5 Factor of Safety against Overturning > 2 0 Factor of Safety against Bearing Capacity Failure > 2 0 5 6 Excavation Considerations All areas of excavation should meet the requirements of the most current Occupational Safety and Health Administration (OSHA) 29 CFR Part 1926, "Occupational Safety and Health Standards -Excavations" The type of excavation support system should be carefully considered based upon the construction and design requirements for the project The design of excavation support systems is beyond the scope of this exploration Excavation safety should be the sole responsibility of the contractor and their subcontractors 5 7 Pavement Design Considerations For the design and construction of exterior pavements, the subgrades should be prepared in strict accordance with the recommendations in the "Subgrade Preparation" and "Engineered Fill Placement" sections of this report An important consideration with the design and construction of pavements is surface and subsurface drainage Where standing water develops, either on the pavement surface or within the base course layer, softening of the subgrade and other problems related to the deterioration of the pavement can be expected Furthermore, good drainage should minimize the possibility of the subgrade materials becoming saturated during the normal service period of the pavement ECS recommends a light duty flexible pavement section of 2 inches of surface SF9 5 mix overlying at least 6 inches of compacted ABC stone In the parking and drive aisle areas For a heavy duty flexible pavement section, ECS recommends 3 inches of surface S179 5 mix overlying at least 6 inches of compacted graded aggregate base in the parking and roadway areas For a light to medium duty rigid pavement section, we recommend 6 inches of 650 psi flexible strength concrete overlying at least 6 inches of compacted ABC stone in the roadway areas 10 Report of Subsurface Exploration and Geotechnical Engineering Evaluation Lot 3 BRIM Associates Nt LLC Wilmington, New Hanover County, North Carolina ECS Protect No 22 18078 Regardless of the section and type of construction utilized, saturation of the subgrade materials and asphalt pavement areas results in a softening of the subgrade material and shortened life span for the pavement Therefore, we recommend that both the surface and subsurface materials for the pavement be properly graded to enhance surface and subgrade drainage By quickly removing surface and subsurface water, softening of the subgrade can be reduced and the performance of the parking area can be Improved Site preparation for the parking areas should be similar to that for the building area including stripping, proofrolling, and the placement of compacted structural fill Please note that large, front -loading trash dumpsters frequently impose concentrated front - wheel loads on pavements during loading This type of loading typically results in rutting of bituminous pavements and ultimately pavement failures and costly repairs Consequently, we recommend the use of an 8 Inch thick, mesh reinforced concrete slab that extends the entire length of the truck Concrete pavements should be properly jointed and reinforced as needed to help reduce the potential for cracking and to permit proper load transfer 5 8 Site Drainage Positive drainage should be provided around the perimeter of the structure to help minimize the potential for moisture infiltration into the foundation and slab subgrade soils We recommend that landscaped areas adjacent to these structures be sloped away from the construction and maintain a fall of at least 6 inches for the first 10 feet outward from the structures Roof water should be discharged directly into below -grade stormwater piping or be directed a sufficient distance away from the building with downspouts The parking lots, sidewalks, and any other paved areas should also be sloped to divert surface water away from the proposed building The proper diversion of surface water during site grading and construction will help reduce the potential for delays associated with periods of inclement weather The proper diversion of surface water Is especially critical since portions of the site soils are expected to be moisture sensitive Based upon our past experience, the use of "crowning" large areas of exposed soils should be useful to help divert surface water from the prepared subgrades 5 9 Construction Considerations It is imperative to maintain good site drainage during earthwork operations to help maintain the integrity of the surface soils The surface of the site should be kept properly graded to enhance drainage of surface water away from the proposed construction areas during the earthwork phase of this project We recommend that surface drainage be diverted away from the proposed building and pavements areas without significantly interrupting its flow Other practices would involve sealing the exposed soils daily with a smooth -drum roller at the end of the day's work to reduce the potential for infiltration of surface water into the exposed soils 11 Report of Subsurface Exploration and Geotechnical Engineering Evaluation Lot 3 BRM Associates #1 LLC Wilmington, New Hanover County North Carolina ECS Protect No 22 18078 The key to minimizing disturbance problems with the soils Is to have a proper earthwork operations plan Specifically, it should be the earthwork contractor's responsibility to maintain the site soils within a workable moisture content range to obtain the required In -place density and maintain a durable subgrade Scarifying and drying operations should be Included In the contractor's price and not be considered an extra to the contract In addition, construction equipment cannot be permitted to travel across the site, especially once the desired final grades have been established Construction equipment should be limited to designated lanes and areas, especially during wet periods to minimize disturbance of the site subgrades It will likely be necessary to utilize tracked equipment during grading operations particularly If the subgrade soils exhibit elevated moisture conditions 12 Report of Subsurface Exploration and Geotechnical Engineering Evaluation Lot 3 BRIM Associates #1 LLC Wilmington New Hanover County North

I SP, IA 1111r U,r cC Sr r I,LLL Lk1,T,„� i'P The storm water management system for the Monkey Junction Taco Bell is based stormwater retention (up to and including the 10-year storm event) and stormmwater retention for larger storm events (i e 25-year, 50-year and 100-year storm events) The stormwater retention/detention will be accomplished utilizing the StormTech underground stormwater management system The proposed stormwater management system includes 212 StormTech SC-310 chambers embedded in 6-inch of stone bedding (including bottom top sides and between chambers) The NCDENR Stormwater BMP Manual (16 3 9 4) states If the applicant can demonstrate that the 10 year, 24 hour storm event can be infiltrated without discharging the system using an infiltration rote of one-half of the infiltration rote reported in the sods report no bypass no vegetated filter strip and no additional storage volume is required The proposed system for the site was analyzed using an infiltration rate of 10 in/hr The soils investigation reported a minimum infiltration rate of 214 in/hr at the depth approximately equal to the proposed bottom of the underground detention Additionally the stormwater management system for the site was designed to meet the New Hanover County stormwater management peak discharge requirements These require the post -development peak discharge to be less than the pre -development discharge for the 2- 10- and 24-year storm events The table below summarized the peak discharges for the site Peak Runoff /Discharge(cfs) 2-yr I 10-yr I
