The rules require demonstration of "effective infiltration of the discharge from the pond" in the vegetated filter area. Can you provide calculations for the vegetated filter that demonstrate this requirement has been met? You do NOT have to provide a 2' separation to the SHWT for a secondary BMP. I envision this as a calculation based on the fact that the 2" orifice delivers .08 cfs to the filter over the course of 111 hours (drawdown time) and there is 6,000 square feet of filter area available. I backtracked into the calculation to determine the minimum infiltration rate that would be needed to handle this flow and came up with 0.56 inches per hour. The level spreader and vegetated filter supplement is not yet set up to deal with these items as being a secondary BMP. Some of the information I need to approve this as a secondary BMP is not on the supplement and will need to be covered by the calculations. The soils are not the best for infiltration, but perhaps you could specify excavation of the unsuitable clayey soils in the proposed location of the filter, and backfill with a soil capable of providing an infiltration rate of at least 0.56 inches per hour or better.

The property is located approximately 900 feet east of the intersection of US Highway 70 and NC Highway 101. The site total acreage is 3.65 acres; of this area, the McDonald's restaurant development will be limited to a lease area of 1.44 acres. The proposed site construction will consist of a single -story 4,490 square Foot building with curb islands, associated parking, and above ground stormwater management. Note that the proposed stormwater BMP will be designed for full build out of the entire 3.65 acres. 1.2 EXISTING SITE CONDITIONS The existing site is a vacant open grassed lot. The lot is extremely flat and poorly drains to the perimeter sw'ales. 1.3 ADJACENT AREAS The site is bounded and accessible by US Highway 70 to the north and Carteret Drive to the west. Short Street and Jones Avenue are adjacent to the west and south, respectively. Two relatively small developments (residential and commercial) exist along Jones Avenue to the south of the property. 1.4 CRITICAL EROSION AREAS The most critical erosion area will be the surface of the working area during construction operations. If grass is not established on dormant denuded areas then there is a significant potential for the covered areas to be eroded and for sediment to be carried in the runoff. To m nimize the potential for erosion, covered areas that are temporarily inactive will be seeded within 14 working days after placement of the soil cover. 1.5 EROSION AND SEDIMENT CONTROL MEASURES All vegetative practices and erosion and sediment control features shall be designed, constructed and maintained in accordance with the North Carolina Erosion and Sediment Control Planning Standards and Specifications. The features are designed to control runoff resulting from the 10-year frequency storm. Plan -view drawings with details are provided. 1.5.1 STABILIZED CONSTRUCTION ENTRANCE/EXIT (REFERENCE NCESCPDM STD & SPEC 6.06) Stabilized construction entrances should be used at all points- where traffic will be leaving a construction site and moving directly onto a public road. Wash down facilities may be required as directed by your local approving agency. Construction entrances should be used 2 McDonald's — Beaufort, NC MCD-0817 6/22/2009 5 in conjunction with the stabilization of construction roads to reduce the amount of mud picked up by vehicles. 1.5.2 SILT FENCE (REFERENCE NCESCPDM STD & SPEC 6.62) Sediment fences will be provided downgradient of the proposed site grading at the locations shown on the drawings. The sediment fences will direct flow to either a sediment deposition area behind the fence or to a sediment trap. Silt fences are not to be used across channels or in areas of concentrated Flows. 1.5.3 BLOCK AND GRAVEL INLETPROTECTION (REFERENCE NCESCPDM STD & SPEC 6.52) Block and gravel inlet protection will be utilized on this site. The inlet protections are utilized to help prevent sediment from entering the storm drains before stabilizing the contributing watershed. This practice allows early use of the storm drain system. 1.6 VEGETATIVE STABILIZATION Vegetative cover shall be re-established within 15 working days or 30 calendar days after completion of the activity, whichever period is shorter. Refer to plans for temporary and permanent seeding schedule and specifications. 1.7 TEMPORARY STABILIZATION Disturbed areas will be vegetated in accordance with section 3.0 of the North Carolina Erosion and Sedimentation Control Design Manual and the seeding specifications. ,Temporary control features will remain in place and will be maintained until the up -gradient disturbed area has been stabilized with vegetative cover. 1.8 MAINTENANCE All erosion and sediment control measures will be checked for stability and operation following every runoff -producing rainfall but in no case less than once every week. Any needed repairs will be made immediately to maintain all measures as designed. Sediment fences shall be inspected at least once a week and after each rainfall event. Repairs shall be made immediately. Sediment deposits shall be removed as needed to provide adequate storage volume for the next rainfall event, and to reduce pressure on the fence. Fencing materials and sediment deposits shall be removed, and the area brought to grade following stabilization of upgradient disturbed areas. 1.9 CONSTRUCTION SEQUENCE 1. Schedule a pre -construction conference with the environmental engineer. Obtain a land -disturbing permit- 3 McDonald's — Beaufort, NC MCD-0817 6/22/2009 3 2. Install gravel construction entrance, silt fence, and other measures as shown on the approved plan. Clear only as necessary to install these devices. Seed temporary diversion ditches immediately after construction. See seeding schedule on approved plans. 3. Call for onsite inspection by conservation inspector and obtain certificate of compliance. 4. Begin clearing/grubbing and general excavation onsite. It is the responsibility of the contractor to phase/stage erosion control as necessary to allow for proper construction activity. Note: Contractor shall inspect and repair all erosion devices at least once a week and after every rainfall of V2 inches or greater. Grading activity shall be prohibited in the areas of the sediment control devices until the areas upstream of these devices have been stabilized and approved. 5. lkgin installing upstream storm drainage system. Install approved inlet protection. 'Terminate storm drainage system at erosion control devices until such devices have been approved for removal by the conservation inspector. Additional measures may be required by the inspector due to the rouging of the storm drainage and actual field conditions 6. Stabilize site as areas are brought up to finish grade with vegetation, paving, ditch linings, etc. Seed and mulch denuded areas within 15 days of completion of any phase of construction; all areas shall be stabilized within 21 days. 7. When construction is complete and all areas are stabilized completely, call for inspection by environmental inspector. 8. If site is approved, remove silt fencing, inlet protection, etc. Seed or pave any resulting bare areas. All remaining permanent erosion control devices, such as outlet protection, should now be installed or brought online. 9. When vegetation has become established, call for a final site inspection by the environmental engineer. Obtain a certificate of completion. J McDonald's — Beaufort, NC MCD-0817 6/22/2009 I SECTION 11 - STORMWATER MANAGEMENT 2.1 STORMWATER NARRATIVE Per regulations set forth in the North Carohna 13MP Manual for sites draining to SA waters, storage shall be infiltration systems designed to control runoff from all surfaces generated by the 1.5" rainfall or the difference between the pre- and post -development volume (1-year 24- hour storm), whichever is greater. In areas that infiltration is not suitable, discharge from a stormwater BMP shall be treated by a secondary BMP. Additionally, stormwater management facilities shall be designed to detain the 1-year 24-hour storm event to the pre - development rate. An evaluation of the infiltration rates and seasonal high water table was performed by F_CS Caiolinas, LLP. It was determined that infiltration was unfeasible due to the saturated conditions of the soils. Please refer to this report in Appendix B for additional information. Therefore, in order to satisfy the above stormwater requirements, a water quality pond is proposed that outlets to a level spreader and into a minimum 50 feet vegetated filter. The water quality pond is proposed to drain the difference between the pre- and post - development volumes over aperiod greater than 24 hours. This is achieved by it 3" orifice located on the proposed 5' x 5' riser structure. The level spreader and vegetated filter downstream has been sized for the necessary 13 feet/cfs. The proposed water quality pond provides detention for all storms up to the 100-year storm event. Therefore, no adverse impacts shall be expected upstream or downstream of the proposed development. The following report provides detailed stormwater management calculations for the site and final design calculations for the proposed stormwater wet detention basin. 2.2 CALCULATION METHODOLOGY • Rainfall data was taken from NOAA Atlas 14. This rainfall depth was then input into the meteorological model within PondPack for peak flow rate calculations. Pleasc reference the miscellaneous site data section within this report for additional information. • Soils data for the site was taken from the NRCS web soil survey website (http://websoilsurve),.nres.usda.gov/). Please reference the miscellaneous site data section within this report for additional information. • The on- and off -site topography used in the analysis is from it field survey by Commercial Site Design. • The pre -development time of concentration was assumed to be 30 minutes. No definitive flow patterns could be determined due to the relative flatness of the site. The post -development time of concentration were assumed to be 5 minutes. McDonald's — Beaufort, NC MCD-0817 6/22/2009 �. s PondPack Version 10.0 is used to generate pre- and post -development peak flow rates and model the proposed stormwater management facilities. Output from PondPack is included within this report. 0 McDonald's — Beaufort, NC MCD-0817 6/22/2009 APPENDIX A - SUMMARY OF RESULTS McDonald's — Beaufoil, NC MCD-08 ] 7 6/22/2009 I McDONALD'S - BEAUFORT, NC SUMMARY OF RESULTS J.

Field Testing On November 20, 2008, ECS oondncted an exploration of the subsurface soil and groundwater conditions at six requested locations shown on the attached Test Location Plan (Figure 1). The test areas were field located utilizing a location plan provided by Commercial Site Design. The purpose of this exploration was to obtain subsurface information of the in -place soils for the proposed infiltration area ECS colored the subsurface soil and groundwater conditions by advancing one hand auger boring into the existing ground surface at the six requested boring locations. ECS visually classified) the subsurface soils and obtained representative samples of each soil type encountered. ECS also recorded the groundwater level and the seasonal high water level (SHWL) observed at the lime of each hand anger baring. The attached infiltration Evaluation Form provides a summary of the subsurface conditions encountered at each hand auger boring location. The groundwater level and the SHWL were estimated at each boring location below the existing grade elevation. Below is a suromary of each baring location.

The Wilmington Regional Office received an Express Stormwater Management Permit Application for Jones Company Pont on June 16, 2009, and requested additional information on June 15, 2009. The requested information was submitted on July 9, 2009. 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 level spreader calculations, including how you determined that the 10 year storm peak flow rate is 8.86 efs. Response: Level Spreader calculations provided in Level Spreader Supplement. 8.86 CFS changed to 9.40 CFS due to minor changes, see pond pack calculation on page 45 of the storm water calculation booklet 2. Per the BMP Manual and published technical guidance, the average pond depth should be rounded to the nearest one-half foot. Since the calculated value is 3.38 feet, please enter the SA/DA tables with 3.5 feet. Response: Updated to 3.5', however, the required surface area slightly changed, see wet detention basin supplement and page 37 of the storm water calculation booklet for these changes. 3. The temporary pool elevation. (TPE) reported on the supplement and calculations is 8.56, but the reported temporary pool volume (TPV) appears to be based on the higher elevation of 8.7. The TPE to report on the supplement is that elevation at which the overflow is set, which, according to the pond details, is 8.7 and not 8.56, and the correct TPV to report is the volume provided at the set overflow elevation. Please correct and revise the TPE reported on the supplement and revise the pond cross-section detail to show a TPE of 8.7. Response: Updated TPE to 8.7 on wet detention basin supplement Ms. Linda Lewis Environmental Engineer III July 17, 2009 Page 2 RE AFIVFD .ill- 2 0 2009 BY:_---- 4. Please label Lot A and Lot B on sheet C-2. We need to be able to match them up to the deed restrictions. Response: Lots labeled. Please see plan sheet C-2. 5. The revised deed restriction document needs to be completed, signed, dated and notarized. Response: Deed restriction document will be completed and submitted under a separate package to arrive on 7120. 6. The 1 year 24 hour pre -development discharge rate appears to calculate the Rational C runoff coefficient using the SCS Discrete Curve number method. Please do not mix methods. A suitable range of Rational C runoff coefficient values for an undeveloped wooded site is 0.15 to 0.25. This change will reduce the pre -development discharge rate. Response: Updated C value to 0.25 per comment noted above which changed some numbers slightly. inn addition, the orifice was updated from 3" to 2" Please see wet detention basin supplement and page 36 in the stormwater calculation booklet for these changes. The total forebay volume provided is 23% of the total permanent pool volume, or 12,445 cubic feet. The allowable range is 18%-22%. Please reduce the forebay volume provided to no more than 11,880 cubic feet. Response: Updated the forebay areas to 22% maximum area. See the wet detention basin supplement and page 37 of the storm water calculation booklet for these changes. 8. Per Section 10.3.7 of the June 16, 2009 BMP Manual, a minimum of 50 plants per 200 square feet of shelf area is required. Please revise the required number of Pickeral Weed plants reported on the landscaping plan to reflect the minimum number of plants and the planting density of 50 plants per 200 square feet of shelf. Based on scaling the landscape plan, the shelf is 656' long, so the area is 6560 sf. With 50 plants for every 200 sf required, the minimum number of plants is 1640. Response: Updated to shown 1640 plants per comment. Please see Landscape Schedule on sheet L-1 a. 9. Sheets C-5a and L-1 a both have a note regarding the ten foot vegetated shelf area. This note indicates that the shelf is sloped at 5:1. This is incorrect. The slope of the shelf is a minimum of 10:1. Response: Slope shelf revised to 10:1. See sheets C-5a and C-10 for these changes. 10. With a 10 foot wide shelf at a 10:1 slope, and with half of the shelf above permanent pool and half of it below permanent pool, this correlates to an even shelf width of 5' above and 5' below the permanent pool elevation. However, the pond detail on the landscape plan shows the shelf below the 7.0 contour as being 3 foot wide, and the shelf above the 7.0 contour as being 7 foot wide. Please correct. Response: Updated See sheet L-la. 11. Please provide the dimensions for each contour line and the radius for each cu e-tha'makes up the permanent pool surface area. The dimensions can be placed on either' e.'1 scap Ms. Linda Lewis Environmental Engineer III July 17, 2009 Page 3 Ffill_ 2 0 20 99 BY: plan, on the stormwater plan or as an inset detail on the detail sheet. This will help the Division to verify that sufficient surface area is provided. Response: Provider. See line tables on sheet C-5a. 12. Due to the significant application deficiencies, please submit a reapplication fee of $500.00. Response: A check in the amount of $500 has been included with this resubmitta.

P 9 2009 BY: Please find our response to comments provided June 18, 2009, for the above referenced project. Ponds designed at 90% TSS do not require a vegetated filter. If the increased volume requirement is a problem, you may want to consider designing a vegetated filter as the secondary BMP instead of a whole pond. Please use the 10-year design storm to size the associated level spreader instead of the BMP drawdown rate. Response: The proposed stormwater design Has been revised to a single water quality pond (sized for the appropriate water quality volume discussed) with a level spreader/veg filter downstream sized for the 10 year design storm. See the provided plans and stormwater management calculations. The 2 ponds shown on the plans are the main pond and the required secondary 13MP for SA waters. The discharge from a properly designed secondary BMP is not considered a direct discharge to SA waters. Response: Noted. There are actually 2 separate projects, one being the high density subdivision with a wet pond to serve 2 separate parcels, one of which is McDonalds; and the other is the oflsite application for McDonalds itself. The two applications can be reviewed simultaneously, but a separate offsite application fee is required for McDonalds. At this time, the "Master" wet pond application has been accepted and will be reviewed in Express.'rhe offsite McDonald's project may be submitted into the regular program, depending on schedule. If you choose to Linda Lewis NC Division of Water Quality June 23, 2009 Page 2 utilize Express for the offsite review, please contact Janet Russell to schedule it. Off§ite projects are reviewed for a fee of $2000. Response: Noted McDonald's project will be submitted under the regular review cycle. 4. 1 checked the project location and verified that Turner Creek is SA from its source to Davis Bay. I was confusing Turner Creek with Taylor's Creek, which is SC. Response: Noted 5. Some of the built -upon area for the proposed McDonalds was not being collected. We discussed the need to collect the runoff from these areas and the use of a trench drain and provide revised plans. Response: This will be corrected to the maximum ertent practicable at the time of the McDonald's submittal. The Jones Pond will receive a new permit number but the McDonalds will be permitted under SW8 090526. Response: Noted As I indicated to you in the meeting, I have checked on the use of the SCS curve number method to determine the pre and post development volumes. Per the BM Manual, this method is acceptable only for sites that are submitted under the Low Impact Development rules, which is a totally different concept. The standard method of calculating runoff volume for mainline projects is found in Chapter 3 of the BMP Manual, Section 3.3.1, the Simple Method. Response: The water quality pond has been revised to account far the increased volume. 8. For calculating the 1 year 24 hour runoff volumes, the Rv value for the pre -developed site at zero percent impervious is .05 and the Rv value for the post -developed site will the 0.69 that you'calculated. The Rd value (runoff depth) for both pre and post is the 3.66" from the NOAA chart. Substituting all these variables into the volume equation, V = 3630 * Rd * Rv A(watershed area in acres), results in a difference of 31,550 cubic feet, which is well in excess of the 8,208 you calculated, and in excess of the 13,793 cubic feet that the pond is currently designed for. Response: The water quality pond has been revised to account for the increased volume. Linda Lewis NC Division of Water Quality June 23, 2009 Page 3 9. The application lists the receiving, stream as Town Creek, class SC, but the pond has been designed for SA. We discussed Turner Creek as being the receiving stream, not Town Creek. Response: Noted. This has been revised 10. One thing we did not discuss in the meeting is the orifice sizing. In addition to the 2-5 day drawdown requirement, the flow rate through the orifice is also subject to confirmation that it does not exceed the pre -development flow rate for the 1 year 24 hour storm. Response: Noted This calculation is provided. 11. The predevelopment flow rate is detemrined by the Rational Method equation, Q=CIA as found in Chapter 3 of the BMP manual. C is the predevelopment runoff coefficient (generally about 0.25 for vegetated sites with no BUA), I is the 1 year 24 hr precipitation intensity from the NOAA chart (generally the I yr 24 precipitation depth divided by 24), and A is the drainage area in acres. Response: Noted. This calculation is provided. I2. The average head on the orifice is the total head divided by 3. This provides for a decreasing flowrate as the head decreases. The size of this orifice will probably be increasing to deal with the additional storage needed. Response: Noted This has been revised Please call if you have any questions concerning these responses. Sincerely, COMMERCIAL SITE DESIGN, PLLC J me, D.

Field Testing On November 20, 2008, ECS conducted an exploration of the subsurface soil and groundwater conditions at six requested locations shown on the attached Test Location Plan (Figure 1). The test areas were field located utilizing a location plan provided by Commercial Site Design. The purpose of this exploration was to obtain subsurface information of the in -place soils for the proposed infiltration arc ECS explored the subsurface soil and groundwater conditions by advancing one hand auger boring into the existing ground surface at the six requested boring locations. ECS visually classified the subsurface soils and obtained representative samples of each soil type encountered. ECS also recorded the groundwater level and the seasonal high water level (SHWL) observed at the time of each hand auger boring. The attached Infiltration Evaluation Form provides a summary of the subsurface conditions encountered at each hand auger boring location. The groundwater level and the SHWL were estimated at each boring location below the existing grade elevation. Below is a summary of each boring location.

At the time of our field exploration, the site was open and covered in grass, with a drainage ditch running along the streets. The site was relatively level. We understand that a new McDonald's restaurant will be constructed at the site. Project site grading and structural information was riot available at the time this proposal was prepared, however, we anticipate that new site grades will be similar to existing grades. Approximately 6 inches of organic topsoil was reported:by the drillers at the boring locations. Beneath the surface to a depth of at least 90 feet, the test borings typically encountered layers of loose to very dense silty and clean sands (SM, SP), very soft to stiff sandy clays (CL), and very soft to firm sandy, lean, and fat silts (NM, NIM. In summary, the proposed construction 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 pressure of up to 1,500 pounds per square foot (psi) is recommended.for use in proportioning shallow foundations. However, undercutting should be anticipated in the footing areas due to the presence of soft clays and silts. We request the opportunity to review our foundation recommendations once structural loads are determined.'

ECSProjectNo.:22.14455-A RECETV JEER 1 2.0 PROJECT OVERVIEW JUNI 1 5 2009 2.1 Proiect Information BZ': Our understanding of the proposed development is based upon our discussions with representatives of McDonald's USA, LLC and the site map provided to ECS by McDonald's USA, LLC. The site is located at the comer of Live Oak Street and Carteret Drive in Beaufort, North Carolina. At the time of our field exploration, the site was open and covered in grass, with a drainage ditch running along the streets. The site was relatively level. We understand that a new McDonald's restaurant will be constructed at the site. Project site grading and structural information was not available at the time this proposal was prepared, however, for a typical McDonald's, column and wall loads do not exceed 80 kips per column and 4 kips per linear foot, respectively. 2.2 Scope of Work The conclusions and recommendations contained in this report are based on the results of: • thirteen soil test borings, • visual examination of the samples obtained during our field exploration, • grain size analyses of two samples obtained during our field exploration, • California Bearing Ratio of one sample obtained during our field exploration, • engineering analyses of the field and laboratory findings with respect to the provided project information 23 Purvoses of Eaoloration 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 by: • performing a site reconnaissance to evaluate the existing site conditions, • drilling test borings to explore the subsurface soil and groundwater conditions, • performing grain size analyses on select samples obtained during our field exploration, • performing a California Bearing Ratio analysis on a sample obtained during our field exploration, • analyzing the field data to develop appropriate geotechnical engineering design and construction recommendations.

Hollow -stem auger and mud-mtary drilling was utilized to advance the borings. Representative soil samples were obtained by means of the split -barrel sampling procedure in general conformance with ASTM D-1586. In this procedure, a 2-inch O.D., split - barrel sampler is driven into the soil a distance,of 18 inches by a 140-pound hammer falling 30 inches. The number of blows required to drive the sampler through a 12-inch interval is termed the Standard Penetration Test (SPT) value and is indicated for each sample on the boring logs in Appendix B. The SPT value can be used as a qualitative indication of the in -place relative density of cohesionless soils. In a less reliable way, it also indicates the consistency of cohesive soils. This indication is qualitative, since many factors can affect the standard penetration resistance value (i.e.,differences between drill crews, drill rigs, drilling procedures, and hammer -rod -sampler assemblies) and prevent a direct correlation between SPT resistance value, or N-Value, and the consistency or relative density of the tested soil. Split -spoon samples were obtained at approximately 2.5-foot intervals within the upper 10 feet and at approximately. 5-foot intervals thereafter. The approximate locations of the soil test borings are indicated on the Boring Location Plan in Appendix A of this report. The drilling crew maintained a field log of the soils encountered in the borings. After recovery, each sample was removed from the sampler and visually classified. Representative portions of each soil sample were then sealed in air -tight containers and brought to our laboratory in Wilmington, North Carolina for visual examination and formal classification by a geotechnical engineer in general accordance with the Unified Soil Classification System guidelines. The soil samples collected for this investigation will be retained at our laboratory for a period of sixty (60) days, after which they will be discarded unless other instructions are received as to their disposition 3.2 Laboratory Teslint Proeram Representative soil samples obtained, during our field exploration were selected and tested in our laboratory to check field classifications and to determine pertinent engineering properties. The laboratory testing program included: • visual classifications of soil according to ASTM D 2487; index property testing included natural moisture content determinations (ASTM D 2216), grain size analyses (ASTM D 1140), and California Bearing Ratio. Data obtained from the laboratory tests are included on the Laboratory Testing Summary and in Appendix C of this report. The soil samples collected for this investigation will be retained at our laboratory for a period of sixty (60) days, after which they will be discarded unless other instructions are received as to their disposition. Report of Subsurface Exploration and Geotechnical Engineering Analysis _ Manatee Street McDonald's Restaurant (#032-1426) Beaufort, North Carolina ECS Project No.: 22.14455-A JUN 1 5 2009 4.0 EXPLORATION RESULTS 4.1 Site Conditions The site is located at the comer of Live Oak Street and Carteret Drive in Beaufort, -North Carolina. At the time of our field exploration, the site was open and covered in grass, with a drainage ditch running along the streets. The site was relatively level. 4.2 Reeional Geoloev 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 Soil Test Borings: Approximately 6 inches of organic topsoil were reported by the drillers at the boring locations. Beneath the surface to a depth of at least 90 feet, the test borings typically encountered layers of loose to very dense silty and clean sands (SM, SP), very soft to stiff sandy clays (CL), and very soft to firm sandy, lean, and fat silts (ML, W, . Standard penetration test resistances (N-values) in these soils generally ranged from Weight of Hammer (WOH) to 50 blows per two inches. The descriptions provided in this section are a general summary of the subsurface conditions encountered within the test borings. The Test Boring Records in Appendix B contain detailed information recorded at each of the boring locations and represent the geotechnical engineer's interpretation of the data based on visual examination of the soil samples obtained during the field exploration. The stratification lines on the Test Boring Records represent approximate boundaries between material types and the actual transition between strata is expected to be gradual. 4.4 Groundwater Conditions Groundwater observations were made after the completion of the drilling operations all boring locations. Furthermore, visual observations of the samples retrieved during drilling exploration were also used in evaluating the groundwater conditions. Standing groundwater was observed at 2 feet 7 inches below the existing ground surface after completion of the borings. Report of Subsurface Exploration and Geotechniral Engineering Analysis RJECEl. `%EL Manatee Str xt McDonald's Restaurant (N032-1426) J U N 1 5 2009 Beaufort, North Carolina ECS Project No.: 22.14455-A BY: The highest groundwater observations are normally encountered in the late winter and early spring, and our current groundwater observations are expected to be near or representative of the seasonal maximum water table. Variations in the location of the long-term water'table may occur as a result of changes in precipitation, evaporation, surface water runo$ 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 Laboratory Test Results Index and engineering properties tests were performed on select samples of the sample soils encountered within the test borings. In summary, the tested samples had in -situ moisture contents of 24.6 and 41.5 percent. The grain size analyses of the tested samples indicated that the tested materials had 34.6 and 26.8 percent fines passing the number 200 sieve. The California Bearing Ratio of the soil tested was determined to be 22.2 percent. Specific laboratory test results are provided in Appendix C of this report. Report of Subsurface Exploration and Geotechnical Engineering Analysis ---- Manatee Street McDonald's Restaurant (#032-1426) s Tv Bemefoet, North Carolina ECS ProjectNo.;22.14455-A JUN 1 5 2009 5.0 ANALYSIS AND RECOMMENDATIONS BY: The recommendations provided 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 Subzrade Preuaration The fast step in preparing the site for the proposed construction should be to remove all vegetation, rootmat, topsoil, deleterious materials, and any other soft or unsuitable materials from the existing ground surface. These operations should extend at least 5 feet, where possible, beyond the planned limits of the proposed building. After proper clearing, stripping, grubbing, and prior to fill placement, foundation, slab, or roadway construction, the exposed subgrade soils should be carefully evaluated by an experienced geotechnical engineer to identify any localized unstable or otherwise unsuitable materials. After evaluating the exposed soils, loose and yielding areas should be identified by proofrolling the exposed subgrades, if site and subsurface conditions allow, with an approved piece of equipment, such as a loaded dump truck, having a single -axle weight of at least 10 tons. Any soft or unsuitable materials identified during proofiolling operations should be either repaired in -place or removed and replaced with an approved backfill placed and compacted in accordance with recommendations of this report. Undercutting should be anticipated in approximately half the parking and roadway areas to a depth of 2 to 3 feet due to the presence of soft clays and silts. Site subgrade conditions will be significantly influenced by weather conditions. Subgrades that are evaluated after periods of rainfall will not respond as well to proofiolling as subgrades that are evaluated after periods of more favorable weather. We strongly recommend that rubber tire equipment not be used. The contractor should use tracked equipment to minimize the degradation of marginally stable subgrade. The preparation of fill subgrades, as well as proposed building subgrades, should be observed on a full- time basis by a representative of ECS. These observations should be performed by an experienced geotechnical engineer, or his representative, to ensure that all unsuitable materials have been removed and that the prepared subgrade is suitable for support of the proposed construction and/or fills. 5.2 En2ineered Fill Placement Following the removal of all vegetation, rootmat, topsoil, and deleterious materials, and after achieving a stable subgrade, engineered fills can be placed and compacted to achieve the desired site grades. All fill for support of the proposed construction and for backfill of utility lines 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 40 and 20, respectively. We also recommend that all fills within structural areas have a standard Proctor (ASTM D 698) maximum dry density of at least 110 pounds per cubic foot (pef). 6 Report of Subsurface Exploration and Geotechnical Engineering Analysis u�i�✓r' ` Manatee Street McDonald's Restaurant (H032-1426) i 5 2009 Beaufort, North Carolina J U N ECS Project No.: 22.14455-A BY: _--_- Unsuitable fill materials include topsoil, organic materials (OH, OL), and high plasticity clays and silts (CH, MH). All 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. An examination of the soils recovered during our current exploration, and our previous experience in the area, indicates that the majority of the on -site soils will generally be suitable for re -use as engineered fill. However, it is expected that moisture conditioning of the fill soils will be required during placement to facilitate proper compaction. In some areas, substantial drying may be needed and it may not be feasible to attempt to re -use such materials 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 geotechnical engineer. The geotechnical 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 geotechnical engineer at least 3 to 5 days prior to their use in the field to allow for the appropriate laboratory testing to be performed Fill 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. ABC stone should be compacted to 100 percent of the stone's modified Proctor (ASTM D 1557) maxin nm 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. All filling operations should be observed on a fall -time basis by a qualified representative of ECS 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 suitable remedial activities in order to achieve the required compaction. Fill materials should not be placed on frozen, frost -heaved, and/or soils which have been recently subjected to precipitation. All 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, all 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. Report of Subsurface Exploration and Geotechnical Fagineering Analysis RE CEIV JE` Manatee Street McDonald's Restaurant (#032-1426) Beaufort, North Carolina J U N 1 5 2009 ECS Project No.: 22.14455-A 53 Foundation Recommendations Provided the subgrade preparation and earthwork operations are completed in strict accordance with the recommendations of this report, the proposed construction 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 up to 1,500 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, all 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. We request the opportunity to review our foundation recommendations and make, any necessary changes once structural loads and site design grades are determined. 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 suitable for foundation construction. These evaluations should include visual observations, band 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 footing subgrade should be checked following footing excavations to determine if undercutting is required. Undercutting to a depth of 2 feet below the bottom of footing elevation is expected in half the footings. 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 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 '/z of the anticipated total settlement. This evaluation 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.

Our findings indicate that a modulus of subgrade reaction (k,) of 100 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. We recommend that all 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 rninimithe 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 all slabs -on -grade be underlain by a minimum of 4 inches of open graded aggregate or sand with less than 3% fines to help prevent the capillary rise of subsurface moisture from adversely affecting the slab. If floor covering such as tile 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 Seismic Site Class Determination and Liquefaction Potential The 2006 Edition of the International Building Code (IBC) requires that a seismic Site Class be assigned for new structures. The seismic Site Class for.the site was determined by calculating a weighted average of the N-Values of the overburden to the depth of rock/refusal. The method for determining the weighted average value is presented in Section 1615.1.5 of the IBC 2003. The weighted average value for the site is 6.8 blows per foot. Based on the results of the soil test borings and our evaluation of the site, the site has a seismic classification `B". Based on the USGS Seismic Hazard Curves and Uniform Hazard Response Spectra 2003 NEBRP Seismic Design Provisions and the IBC 2006, for a seismic site class "B" at latitude 34.725 degrees and longitude-76.644 degrees, the Sns value is 0.245g and the SDI value is 0.142g. The seismic design category depends on the design use of the building and should be determined by the structural engineer. The potential for liquefaction at the site is considered low based upon the soil borings and procedures developed by Seed and Idriss. Based on our soil boring results and our evaluation using a site specific peak ground acceleration of 0.098g and an earthquake event with a magnitude of 7.0, the liquefaction induced settlement at the subject site is anticipated to be less than 1 inch. 5.6 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.

We were provided with details regarding traffic conditions at the site by McDonald's USA, LLC. We understand that parking areas will receive primarily automobile traffic on the order of 2,500 passenger cars per day, but the entrances and service drives will be subjected to some trafficking by heavy trucks, assumed at 4 delivery/dumpster trucks per day. We have calculated approximate equivalent axle loadings of 10,000 and 100,000 for light -duty and medium -duty pavements,' respectively. McDonald's USA, LLC has also provided us with a minimum pavement section of 3 inches of hot mix asphalt over 6 inches of compacted aggregate base. Materla!

The asphalt concrete surface course materials, asphalt concrete binder course materials, and underlying aggregate,base come materials should conform to the North Carolina Department of Transportation Standard Specifications. Careful selection of the asphalt binder and surface course mixes should be made based upon the anticipated traffic conditions for the facilities. 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. Similarly, drive-thm lanes also have an elevated risk of pre -mature distress. Therefore, we suggest that the pavements in trash pickup and drive-thru areas utilize the aforementioned Portland Cement Concrete (PCC) pavement section. It may be prudent from an economical standpoint to use rigid pavement sections in all areas planned for heavy truck traffic. Such a PCC section would typically consist of 6 inches of 4,000 psi concrete over not less than 6 inches of compacted aggregate base course. Appropriate steel reinforcing and jointing should also be incorporated into the design of all PCC pavements. 10 Report of Subsurface Exploration and Geotechnical Engineering Analysis , Manatee Street McDonald's Restaurant(#032-1426) RFiC 1`V Beaufort, North Carolina ECSProjectNo.:22.14455-A JUN 1 5 2009 5.7 Site Drainn Positive drainage should be provided around the perimeter of the structure to minimise 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 fast 10 feet outward from the structures. 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. 5.8 Construction Considerations 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 are softened by surface water absorption or exposure to the environment, the softened soils must he 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 1 to 3 inch thick "mud -mat" of "lean" concrete be placed over the exposed bearing soils before the placement of reinforcing steel. 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,pmject. 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. The key to minimizing disturbance problems with the soils is to have proper control of the earthwork operations. Specifically, it should be the earthwork contractor's responsibility to maintain the site soils within a workable moisture content range to obtain the required m-place density and maintain a stable 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 randomly run 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. 11 �.

Tlus report does not reflect specific variations that may occur between test locations. The borings were located where site conditions permitted and where it is believed representative conditions occur, but the full nature and extent of variations between borings and of subsurface conditions not encountered by any boring may not become evident until the course of construction. If variations become evident at any time before or during the course of construction, it will be necessary to make a re-evaluation of the conclusions and recommendations of this report and further exploration, observation, and/or testing may be required. This report has been prepared in accordance with generally accepted soil and foundation engineering practices and makes no other warranties, either expressed or implied, as to the professional' advice under the terms of our agreement and included in this report. The recommendations contained herein are made with the understanding that the contract documents between the owner and foundation or earthwork contractor or between the owner and the general contractor and the caisson, foundation, excavating and earthwork subcontractors, if any, shall require that the contractor certify that all work in connection with foundations, piles, caissons, compacted fills and other elements of the foundation or other support components are in place at the locations, with proper dimensions and plumb, as shown on the plans and specifications for the project. Further, it is understood the contract documents will specify that the contractor will, upon becoming, aware of apparent or latent subsurface conditions differing from those disclosed by the original soil investigation work, promptly notify the owner, both verbally to permit immediate verification of the change, and in writing, as to the nature and extent of the differing conditions and that no claim by the contractor for any conditions differing from those anticipated in the plans and specifications and disclosed by the soil studies will be allowed under the contract unless the contractor has so notified the owner both verbally and in writing, as required above, of such changed conditions. The owner will, in turn, promptly notify this firm of the existence of such unanticipated conditions and will authorize such further investigation as may be required to properly evaluate these conditions. Further, it is understood that any, specific recommendations made in this report as to on -site construction review by this firm will be authorized and funds and facilities for such review will be provided at the times recommended if we are to be held responsible for the design recommendations. F ECFTV.EDUN 15 7.f1U9_�_ APPENDIX E PROCEDURES REGARDING FIELD LOGS, LABORATORY DATA SHEETS AND SAMPLES 1 Procedures Reeardine ;Field Logs. Laboratory Data Sheets and Samples In the process of obtaining and testing samples and preparing this report, procedures are followed that represent reasonable and accepted practice in the field of soil and foundation engineering. Specifically, field logs are prepared dining performance of the drilling and sampling operations which are intended to portray essentially field occurrences, sampling locations, and other information. Samples obtained in the field are frequently subjected to additional testing and reclassification in the laboratory by more experienced soil engineers, and differences between the field logs and the final logs exist The engineer preparing the report reviews the field and laboratory logs, classifications and test data, and his judgment in interpreting this data, may make further changes. Samples are taken in the field, some of which are later subjected to laboratory tests, are retained in our laboratory for sixty(60) days and are then discarded unless special disposition is requested by our client. Samples retained over a long period of time, even if sealed in jars, are subject to moisture loss which changes the apparent strength of cohesive soil generally increasing the strength from what was originally encountered in the field. Since they are then no longer representative of the moisture conditions initially encountered, an inspection of these samples should recognize this factor. It is common practice in the soil and foundation engineering profession that field logs and laboratory data sheets not be included in engineering reports because they do. not represent the engineer's final opinions as to appropriate descriptions for conditions encountered in the exploration and testing work. On the other hand, we are aware that perhaps certain contractors submitting bids or proposals on work may have an interest in studying these documents before submitting a bid or proposal. For this reason, the field logs will be retained in our office for inspection by all contractors submitting a bid or proposal. We would welcome the opportunity to explain any changes that have been and typically are made in the preparation of our final reports, to the contractor or subcontractors, before the firm submits the bid or proposal, and to describe how the information was obtained to the extent the contractor or subcontractor wishes. Results of the laboratory tests are generally shown on the boring logs or described in the extent of the report, as appropriate. The descriptive terms and symbols used on the logs are described on the attached sheet, entitled General Notes.

" Sent: Monday, June 15, 2009 12:33 PM JUN ] 5 2009 To: Jon Aldridge; Leo Van Buuren (leo.vanbuuren@us.mcd.com) Cc: Russell, Janet; Baker, Chris Subject: McDonalds & Jones Pond BY: _ Jon & Leo: Thanks for your patience this morning. Hope your trip back to Raleigh was safe and uneventful. A summary of our meeting with regard to stormwater management: The 2 ponds shown on the plans are the main pond and the required secondary BMP for SA waters. The discharge from a properly designed secondary BMP is not considered a direct discharge to SA waters. There are actually 2 separate projects, one being the high density subdivision with a wet pond to serve 2 separate parcels, one of which is McDonalds; and the other is the offsite application for McDonalds itself. The two applications can be reviewed simultaneously, but a separate offsite application fee is required for McDonalds. At this time, the "Master' wet pond application has been accepted and will be reviewed in Express. The offsite McDonald's project may be submitted into the regular program, depending on schedule. If you choose to utilize Express for the offsite review, please contact Janet Russell to schedule it. Offsite projects are reviewed for a fee of $2000. 1 checked the project location and verified that Turner Creek is SA from its source to Davis Bay. I was confusing Turner Creek with Taylor's Creek, which is SC. Some of the built -upon area for the proposed McDonalds was not being collected. We discussed the need to collect the runoff from these areas and the use of a trench drain and provide revised plans. The Jones Pond will receive a new permit number but the McDonalds will be permitted under SW8 090526. As I indicated to you in the meeting, I have checked on the use of the SCS curve number method to determine the pre and post development volumes. Per the BMP Manual, this method is acceptable only for sites that are submitted under the Low Impact Development rules, which is a totally different concept. The standard method of calculating runoff volume for mainline projects is found in Chapter 3 of the BMP Manual, Section 3.3.1, the Simple Method. For calculating the 1 year 24 hour runoff volumes, the Rv value for the pre -developed site at zero percent impervious is .05 and the Rv value for the post -developed site will the 0.69 that you calculated. The Rd value (runoff depth) for both pre and post is the 3.66" from the NOAA chart. Substituting all these variables into the volume equation, V = 3630 * Rd * Rv * A(wate:rshed area in acres), results in a difference of 31,550 cubic feet, which is well in excess of the 8,208 you calculated, and in excess of the 13,783 cubic feet that the pond is currently designed for. One thing we did not discuss in the meeting is the orifice sizing. In addition to the 2-5 day drawdown requirement, the flow rate through the orifice is also subject to confirmation that it does not exceed the pre - development flow rate for the 1 year 24 hour :storm.
