Grays Creek Medical Building Table of Contents DESIGN NARRATIVE 1" Runoff Treatment Calculations Detention Pond Stage Storage Deed Book 08557 Page 0125 Geotechnical Engineering Report SCS Soils Information Stream Classification Grays Creek Medical Building DESIGN NARRATIVE Southeastern Regional Medical Center is proposing to construct a permanent medical facility to replace a temporary one on an adjacent lot leased from the Prewitt's. This facility will be constructed on two lots purchased from the Prewitt's adjacent to Pait's Place burgers on Chickenfoot Road in southern Cumberland County. An existing common drive off of Chickenfoot Road will serve both sites. Construction will involve the building, adjacent parking, a temporary sediment basin to be converted to a permanent stormwater basin, and water and sewer construction. Some drainage modifications and grading along the existing state road will direct offsite drainage away from the proposed construction. The adjacent Prewitt erosion control measures will have to be modified to be located only on the Prewitt property. A total of 2.95 acres of new disturbed area will be involved. A permanent storm drainage system will direct the runoff to the permanent stormwater basin when complete. Figure 1 - USGS The project site is currently cleared and grassed. The waters run into Grays Creek (Stream Index Number 18-31-(1)) which eventually runs to Rainey Pond. The highest area is near the state road and the property drains from front to back. An existing sanitary sewer easement runs along the rear of the site. Other than tying into an existing manhole, no land disturbing will occur in the easement area. A portion of Pait's Place burgers drains toward our site and the storm runoff will have to be picked up within our storm drainage system. The area surrounding the site is all Prewitt land and mostly commercial. Existing wetlands and an existing sanitary sewer easement run adjacent to the commercial on the northeastern side and separates the commercial from residential and woodland. The soils on the property consist of Wagram Loamy Sand (WaB). WaB is a part of hydrologic group A according to USDA Natural Resources Conservation Service. The surface runoff rating for these soils is medium to low.

The drainage basin the wet detention pond has been sized for the 2.35 acre area which includes the impervious areas from the proposed, future and some existing offsite areas. The total impervious area of this drainage basin is is 1.64 acres sf , 69.75% of the drainage area. The amount of impervious area and the use of the curb and gutter and storm pipe collection systems makes this a high density project, per 15A NCAC 2H.1005 (3a) of the Administrative Code. Because the project is high density, stormwater treatment will be provided in an on -site wet detention pond. Site runoff will be transported to the pond via overland flow, concrete curb and gutter and a network of stormdrain pipes that have been sized for a 10 year storm events. The pond has been sized to provide treatment for the first 1" of runoff and during the construction of the project the stormwater detention pond will be used as a sediment basin. Pond "A" NC DENR Retention Calculation and Requirements Objective: design a wet detention basin with the following characteristics., a permanent water pool depth between 3- and 8-feet, a surface area that meets TSS removal requirements (values set by NC DENR and included here), a forebay that is approximately 20% of the total pond volume, a temporary water pool sized to detain the initial 1 inch of rainfall runoff, an outlet device that drains the temporary water pool within 2-5 days, and a length -to -width ratio of approximately 3: 1.

PROJECT DESCRIPTION We understand that a single -story 11,000 square foot medical building is planned on a recently cleared parcel tin Chickenfoot Road near its intersection "ith Celebration Drive in Hope Mills. North Carolina. A preliminary site grading plan dated February 28, 2011 provided by Peterson Associates and based upon die existing grades, the building pad will receive as much as 2 to 3 feet of rill. The proposed building; final floor elevation is 162 feet. At the time of our drilling the site had been cleared of trees And had been rough graded,.but not to final grades. Associated parking and driveway areas, and a wet detention basin will also be constructed. We understand the new building will be steel -frame with a concrete slab -on -grade. Structural loads were provided by Fitzpatrick Engineering Group Y1.1-C, with column loads ranging from 6 to 84 kips. Additionally, an off -site borrow source located in a horse pasture, at the Prewitt propeny off of Celebration Drive has also been identified as a potential borrow area for this project. Z. EXPLORATION PROCEDURES S&ME, Inc. drilled five (5) soil test borings (designated B-1 through B-5) to obtain subsurface information within the proposed building footprint (and future footprint) and parking lot areas, t3oring 13-5 was offset about 20 feet nonheast of the planned location due to the nearby overhead powerlines. Boring locations were selected and located in the field by S&ME personnel by measuring distances from the existing site features. Since the borings were established without survey control, their locations should be considered approximate. The approximate baring locations are shown on the Boring Location Plan, Figure 1 in the Appendix of this report. The borings were drilled to depths ranging from 5 to 50 feet below existing grades. Borings were performed using 3 %-inch hollow stem augers and 2'/-inch tricone wash drilling procedures with a CME-550x drill rig mounted on an all -terrain vehicle. Samples of subsurface soils were obtained at 2.5-foot intervals above a depth of 10 feet and at 5- foot intervals below 10 feet using a split spoon sampler. Standard penetration testing (SPT) was performed in conjunction with split -spoon sampling in general accordance with AS'1'M D 1586. The CME-55OX drill rig used to drill the borings is equipped with a hydraulic automatic hammer for Standard Penetrations tests rather than the traditional rope; cathead and safety hammer. The N-values reported on the attached Boring Logs arc the actual field measured blow counts and are not corrected for the haminer onergy. Borehole B-5 was backfllled using auger cuttings after drilling completion and borcholes B-1 through B-4 were back611ed aller the 24-hour water level reading. Split -spoon samples obtained from standard penetration testing were transported to, our laboratory 3 Geotechnical Engineering Report Proposed Gray's Creek Medical Building Hope Mills, North Carolina S&ME Project No_ 1031-11-104 March 14, 2011 and visually classified in general accordance with Unified Soil Classification Sys tern (USCS) guidelines Generalized Subsurface Profile dra%Ning (Figure 2) and Boring Logs presenting specific subsurface information from the borings are included in the Appendix. Stratification lines shown on the Boring Logs and profile are intended to represent approximate depths of changes in soil types. Natural transitional changes in soil types are often gradual and vary in both the horizontal and vertical directions. Boring elevations indicated on the lofts were interpolated from the grading plans mentioned earlier. These elevations should be considered approximate since they were not sun eyed. An auger only boring (designated B-b) was also performed at the proposed off -site borrow source located in a horse pasture, at the Prewitt properly off Celebrtition Drive, to obtain a bulk soil sample. The borrow- location for the bulk soil sample was identified in the field by Mr. Ronald Williams of Moorman, Kizer, and Reitzel, Inc_ The bulls sample collected from auger cuttings was laboratory tested for natural moisture and standard Proctor compaction. 3. SUBSURFACE CONDITIONS Details of subsurface conditions encountered in borings are presented on the Boring Logs in the Appendix, and represent our interpretation of subsurface conditions encountered based upon the driller's field lobs and our visual examination of split -spoon samples. General subsurface conditions are discussed in the following paragraphs. 3.1 Natural Soils Tlic site has been cleared and grubbed of tree stumps at the: time of our exploration, therefore no topsoil was encountered within borings. Natural soils were encountered from the ground surface to boring termination depths. Li general, the natural soils consisted of inter -bedded layers of silly and clayey sands (classified as Slut, SP-SK SP, SC-STV1 and SC) and silty clays (classified as CH). Standard penetration test (SPT) N-values,ranged from I to 26 blows per root (bpt� in the sands and 2 to 23 bpf in the clay; indicating very loose to medium dense relative density for sands and very sots to very stiff' consistency for clay. Loose clayey sands (N-value of 4 to d bpf} were encountered from the existing ground surface to about 3 feet within borings, except boring 13.1. A very soft to stiff silt} clay layer (Nv value of 2 to 4 bpf) was encountered from about 13 to 22 feet below the existing ground surface within the borings. Based on the borings, this clay layer is about 5 feet or less. A very loose to loose sand layers (N-values of I to 5 bpf) was also encountered from about 12 to 25 feet above and below the clay layers in the borings. Natural soils were damp to wet. 3.2 Subsurface Water Watcr was observed in borings 13-1 through B-4 from 8.3 to 13.8 feet, at the time of drilling completion. A temporary piezometer (PVC pipe) was installed in boring B-2 in 4 Geotechnical Engineering Report SWE Project No. 1031-11-104 Proposed Gray's Creek Medical Building March 14, 2011 Hope Mills, North Carolina order to facilitate measurement of subsurFace water. The temporary piezometer was removed after the 24-hour water level reading and the boreholes backfilled using Auger cuttings. Long term monitoring of water levels requires installation of piezorneters which was beyond`the scope of our services. It is important to realize that groundwater levels will fluctuate with changes in rainfall, evaporation rates, near -by construction activity and may occur at higher elevations at other times of the year. in addition, `perched" water conditions can be present within sand layers overlying less permeable materials (such as clay), especially after rainfall. 3.3 Laboratory Test Results A standard Proctor moisture -density test (ASTN4 D698) was performed on a bulk sample obtained from boring B-6. '1'lic soil cuttings were blended from soil obtained between depths of 1 to 10 feet. The results of the tests indicate, a maximum dry density of 119.7 pounds per cubic foot (pef) with an optimum moisture content of 12 percent. The natural moisture content of the sample was 13.3 percent. 4. CONCLUSIONS LINO RECOMMENDATIONS 4.1 Limitation of Report This report has been prepared in accordance with generally accepted engineering practice for specific application to this project. j"y wetland, envirorunental, or contaminant assessment efforts are beyond the scope of this geotechnical exploration; and therefore, those issues are not addressed in this geotechnical exploration report. The recommendations contained in this report are based on the applicable standards of our profession at die time this report was prepared. No other warranty; express or implied; is made. Analysis and recommendations submitted in this report are based upon the data obtained from the geotcchnical exploration and'our understanding of the proposed construction. The nature and extent of variations between and outside of the boring locations may not become evident until construction. If variations appear evident, then it will be necessary to re-evaluate the recommendations of this report. In the event that the assumptions presented in this report regarding site grades, design, structural loads or location of the proposed structures are incorrect, the recommendations contained in this report should be reviewed and modified or verified in writing. We strongly recommend S&ME be provided the crppurtunity to review the final design plans and specifications in order that our earthwork- and foundation recommendations are properly interpreted and implemented. Tie recommendations in this report are contingent on SRME, inc.'s observation and monitoring of grading and foundation construction activities. 5 Geotechnical Engineering Report S&ME Project No. 1031-11-104 Proposed Gray's Creek Medical Building March 14, 2011 Hope Mills; North Carolina 4.2 General Assessment Ise general., the subsurface conditions at this site appear suitable for support of the proposed single -story structure on shallow foundations provided the site is prepared in accordance with the site grading recommendations presented below. The primary geotechnical concern at this site is the very loose to loose near -surface sands found at most boring locations which will need to be repaired prior to till placement in the building; and pavement areas. Repair of these loose surface soils will most likely involve in -place densifcation or undercut and replacement. Because of these loose near Surface soils, all footing excavations will need to be evaluated for adequate bearing support by the,geotechnical engineer prior to placement of reinforcing steel and concrete. Layers of coEnpressible clay are present at depths of between about 13 and 22 feet below existing grade at this site. The soil clays are deep enough that they will not be significantly influenced by the anticipated structural loads of the building (i.e., maximum column loads of 84 kips). However, the placement of widespread loads at the surface such as from the planned fill wrill induce deeper soil stresses and cause the clay laver to slowly consolidate. If fill placements exceed 5 feet under proposed and future building areas plus 10 feet beyond, then waiting periods will be required. To reduce total post - construction settlements and pre -load or pre -settle the soil clay laver due to the weight of the planned till, we recommended that the new fill (placed above existing site grades) be placed at (cast 30 days in advance of settlement -sensitive building construction. Our general rocorntnendations regarding site preparation, subgrade repair, field evaluations, and foundation support are presented in the following sections of this report. 4.3 Site Preparation At the time,of our exploration, the site had been cleared and grubbed. The exposed subgrades in till areas as well as finished subgrades in cut areas should be thoroughly rolled with a large vibratory roller operating at walking speed in order to help densify the near surface sandy soils. At least four complete passes should be made over all subgrade areas with two passes perpendicular to the earlier two. During the in -place soil densification the geotechnical engineer should observe the subgrade reaction to the vibratory equipment and determine if further rolling or other repair measures are warranted. It should be expected that nzirilmal subgrade unprovemcnt with the vibratory roller will occur in areas where the sands contain appreciable silt and clay. In these areas, other possible repair measures could include. undercutting to stable soils and backfilling with well -compacted, low -plasticity materials, discing of in -situ soils to dry to proper moisture content and then re -compacting, placement of eeotextile stabilization fabric on unsuitable materials and placement of crushed stone, or some combination of these. The most practical repair measure will be influenced by the degree of instability which exists and weather conditions. As such, actual repair measures should be detennined by the Oeotechnical Engineer in the field at time of construction. 6 Geotechnical Engineering Report S&ME Project No. 1031-11-104 Proposed Gray's Creek Medical Building March 14, 2011 Hope Mills, North Carolina Site grading will be difficult during periods of extended rainral l that generally occur during the typically wetter winter months. When wet, soils tend to rut and pump under rubber-tircd traffic and provide poor subgrade support for foundations, floor slabs, and pavements. To reduce potential earthwork problems, site preparation and grading should be scheduled during the drier months of May through November, if possible. If grading operations are conducted during wet winter months, delays and additional undercutting costs should be expected, Even during drier periods of the year. Nye recommend that the exposed subgrades be sloped and "sealed" at the end of each day to promote runoff' and reduce infiltration from ruinfull. 4.3.1 Structural Fill Structural fill placed within building and pavement areas should be low plasticity (plasticity index less than 20) and free of debris and organics. Structural fill should have a rnininium dry density of 100 pounds per cubic foot based on the laboratory standard Proctor (AS-I'M D 698) test. We recommend the fill have Unified soil classifications of SP, SW, SM or SC. All structural fill should he placed in 8 to I 0-inch loose lifts and compacted to at least. 95 percent of the standard Proctor maximum dry density (ASTM D 698) except within the final one foot of finished subgrade where this requirement should be increased to at least 98 percent. Soil moisture should he maintained within two (2) percent of the optimum moisture content during compaction. Site preparation including till placement and cornpaCdon should be observed by the project Geotech.nical Engineer or a qualified soils technician. A sufficient number of density tests should be conducted on each sail lift to evaluate whether adequate compaction has been achieved prior to additional fill placement or foundation construction. In areas where 5 feet or more of new till will be placed beneath proposed building and future building footprints plus ten feet beyond, we recommend that several settlement hubs be installed at the top of the compacted dill to monitor settlements. The elevation readings on the hubs should show that rill settlement has stabilized prior to concrete placements. We estimate that about 50 days be accounted for waiting periods prior to building construction. 4.4 Foundation Recommendations 4.4.1 Shallow Foundations Following site preparation, undercutting operations, fill placement, and any subgrade repair work as recommended in this report; the building may be supported on shallow spread footings designed for a maximum allowable soil bearing pressure of 2,000 pounds per square. fooi (psf). Continuous wall footings should be a minimum of 18 inches N%ide and isolated column footings should be at least 24 inches wide to help prevent localircd 7 Geotechnical Engineering Report UME Project No. 1031-11-104 Proposed Gray's Creek Medical Building March 14, 2011 Hope Mills, Nonh Carolina or "punching" shear failure which can occur with very narrow footings. Foundations should be embedded at least 18 inches below finishers exterior grades to provide adequate embedment against t rost penetration. After the excavation process, the exposed foundation bearing soils should be compacted using suitable equipment to density surface soils disturbed during the excavation process. If rainwater collects in foundation excavations, it should be removed promptly to help prevent softening of foundation supporting soils. To further reduce the potential for deterioration of bearing soils, we recommend that foundation excavation and placement of concrete be conducted on the same day if practical. 4.4.2 Foundation Evaluation The Geoteclutical Engineer or his representative should evaluate the foundation bearing conditions prior to placement of reinforcing steel and concrete. This evaluation sllauld include performing shallow hand auger borings with dynamic cone penetrometer (DCP) testing to evaluate the suitability of underlying soils for foundation support. Foundation excavation or exposure to the envirorunent will cause the bearing surface soils 10 loosen or soften. Softenediloosened soils at the foundation surface bearing should be removed or densified in -place with suitable compaction equipment. Any excessively loose;soil soils or other unsuitable materials should -be repaired prior to concrete placement. Repairs are typically performed by undercutting unsuitable soils and baekftlling with washed NCDo,r No. 57 stone, or lowering the foundation bearing level to more competent bearing soils. 4.4.3 Slabs -on -Grade The floor slab design should include isolation of the slab from column and wall footings to allow for relative displacement. The slab-ua-grade should be constructed above newly -placed, well compacted stnictural till. We recommend that a minimum of 4 incites of compacted crushed aggregate base course i'CABC) underlain by a suitable plastic vapor barrier be considerc-d for placement beneath the floor slab to provide more uniform slab support and to reduce damage to wbgrade soils by construction traffic. Exposure to the enviranmenr and construction activities will cause subgrade soils to become unstable. Therefore, we. recommend that subgrade soils in slab areas be evaluated just prior to crushed stone placement. If deterioration of the soils has occurred, undercutting and soil replacement may be necessary. !assuming a 4-inch CABC stone layer is placed, the slab - on -grade may be designed using a subgrade modulus of 120 pci. 4.4.4 Anticipated Settlements The results of the building settlement analysis, which was based on an allowable soil bearing pressure of 2,000 pounds per square Coot and column lop ds of 84 kips or less indicate total foundation settlements will be on the order of 1 inch or less provided that our recommendations in this report are followed. This magnitude of settlement is based on the near surface loose sandy soils being repaired during site,grading, any isolated footings having loose soils at the bearing elevation are repaired and compacted fill depths are no greater than 5 feet. We expect differential settlements Geotechnical Engineering Report SBME Project No. 1031-11-104 Proposed Gray's Creek Medical Building March 14, 2011 Hope Mills, North Carolina will be 112 inch or less following implementation of the recommended site preparation. These settlement magnitudes are expected to be tolerable; however, this should be confirnied by the structural engineer. 4.5 Seismic ConsiderafGons 4.5.1 Site Class Site class was detennined based on the soil conditions encountered by the borings and in accordance with the 2009 North Carolina State Building Code. Based on the soil strength information (Standard Penetration Test (SPT) "N-value") obtained during our subsurface exploration and our experiences in this arcs, a 'Site Class U' is recommended fur design. 4.5.2 Potentiai Liquefaction The liquefaction' susceptibility of the on -site soils was evaluated using the 2009 North Carolina State Building Code design earthquake. Liquefaction is the loss of a soil's slicar strength due to the increase in pore -water pressure resulting from seismic vibrations. Soils most susceptible to liquefaction generally consist of saturated, loose, "clean" (i.e., plasticity indices less than 5), fine (IWo size ranging from 0.07 to 0.25 mm) sands. The results of the liquefaction analysis indicate that the sands at this site have a relatively low potential for liquefaction due to the design earthquake. 4.6 Lateral Earth Pressures Below grade structures must be capable of resisting lateral earth pressures that will be imposed on them. Lateral earth pressures to be resisted will be partially dependent upon the method of construction. Assuming that the walls are relatively rigid and structurally braced against rotation, they shall be designed for a condition approaching, the "at -rest" lateral pressure. However, in the event that the wails are free to deflect during backfilling, as for any exterior walls chat are not restrained or rigidly braced, the "active" pressure conditions will be applicable for design. The following earth pressure parameters are recommended for design based on the on -site soils. These parameters assume a level backfill, a frictionless wall, and no hydrostatic pressure. The recommended lateral earth pressure coefficients and equivalent fluid pressures do not consider the development of hydrostatic pressure behind the earth retaining; wall structures. As such, positive wall drainage must be provided for all earth retaining; structures. These drainage systerns can be constructed of open -graded washed stone isolated from the soil backfill with a non -woven geosynthctic filter fabric and drained by perforated pipe, or several wall drainage products which are made specifically for this Liquefaction is the loss ora wil'sshrar strength due to the in.,rmw in pmc water precsurti: ru:w!tiog from seismic vibrations. ` Thr 2006 IDC design earthquakm has a 98%probability of non-meedance in 50 years.

The soil backfill placed hehind retaining walls shall be compacted to 95 percent of the soil's standard Proctor maximum dry density. We caution that operating compaction equipment directly behind the retaining structures can create lateral earth pressures far in excess of those recommended for design resulting in structural distress. Therefore, bracing of the walls may be needed during backtilling operations. 4.7 Penrnanent Cut and Fill Slopes Permanent cut and fill slopes should have side slopes of at least 2(H):l(V) or flatter for long term stability and erosion control for embankment heights of 10 feet or less. lfslope heights will be greater than 10 feet their stability should be evaluated by a geotechnical engineer to determine the appropriate slope configuration. If mowing of slopes is to be conducted. slopes of 3(H ):l(V j or flatter will be required. If seepage is obscured along permanent out slopes, flattening of the slope angle, installation of a toe or blanket drain or other measures may be required to improve long-term stabilit),. Based on our expericnce, compaction equipment often has difficulty compacting soils along the faces of fill slopes. As such, we recommend that fill slopes be. slightly overbuilt and then cut back to the design geometry, leaving the slope face compacted to the required degree. Rainwater should be diverted away from the top edges of slopes. Slope surfaces should be vegetated as soon as practical aver grading. 4.8 Pavement Considerations S&Mr %as not provided traffic frequency or vehicle weight information and thus a detailed pavement thickness design was not conducted. However, based upon the in Geotechnical Engineering Report UME Project No. 1031-11-104 Proposed Gray's Creek Medical Building March 14, 2011 Mope Mills, North Carolina number of parking spaces and typical car traffic for parking areas, we generally recommend a minimum pavement section consisting of 2 inches of asphalt underlain by 6 inches of aggregate base course (ABC) stone. In the main access drives and truck (dumpster) routes, we generally recommend a minimum of 3 to 4 inches of asphalt underlain by 8 inches of aggregate base course. These thicknesses arc based on our experience, and assume that the subgrade soils are well compacted and consist of soils comparable to those we laboratory tested. Design pavement sections should be determined after detailed traffic information is provided and laboratory soaked Californiit Bearing Ratio (CBR) testing; is performed of off site borrow soils samples to verify pavement subgrade design parameters. Prior to till placement or pavement construction, the entire pavement subgrade area should be thoroughly rolled (several passes made) with a large vibratory roller to help densi fy the very loose to loose near surface sandy soils. After the vibratory rolling the subgrade should be evaluated by the project Geotechnical Engineer by observing the proofrolling of exposed soils using a loaded tandem -axle dump truck. Any areas which are observed to be unstable will require repair prior to fill placement or pavement construction. As recommended earlier it should be expected that the loose more clayey and silty sands will need to be undercut and replaced. Specific recommendations regarding subgrade repair are best given in the field by the Geotechnical Engineer at the time of evaluation. Adequate drainage of the pavement subgrade will be critical to pavement performance, as accumulation of water in the subgrade soils and pavement base course will significantly decrease the useful life of the pavement. Finished grades of the pavement should be higher than the surrounding grades, and if necessary, swales or underdrains may be constructed along the sides of the roadway to divert runoff away from the pavement. All materials and workmanship should meet the requirements of NCDOT "S'rondard Specijicalronts for Roads and Slrucrtrres ". 4.9 Construction Considerations If during site grading subsurface conditions are encountered which are different from our test boring findings, SAME will need to further evaluate such conditions. This evaluation should occur in the field as our geotechnical engineer or his representative is monitoring situ grading operations.. 4.9.1 Off Site Borrow The soils obtained and laboratory tested froth the proposed off -site borrow source located in the horse pasture, at the Prc%vitt property, should be suitable for reuse as structural fill provided their moisture content is properly controlled during placement and compaction. Based upon the natural moisture content, these soils were wet of optimum moisture, therefore, prior to structural till placement, moislum conditioning (drying) will likely be required to achieve adequate compaction. Also, to account for possible wet weather, additional drying time should be expected to achieve adequate compaction. Drying can 11 Geotechnical Engineering Report SUIE Project No. 1031-11-104 Proposed Gray's Creek Medical Building March 14, 2011 Hope Mills, North Carolina normally be accomplished by aerating the soils during, favorable weather conditions (i.e., Sun and wind). 4.9.2 Excavations Difficult to excavate materials were not encountered within the depths of the borings. Soils encountered within the upper ten 1'eet generally consisted of very loose to medium dense sands. Our experience indicates that on -site soils can be excavated using. conventional grading equipment. All excavations should be sloped or shored in accordance with local, state; and federal regulations, including OSHA (29 CFR Part 1926) excavation trench safety standards. The contractor is solely responsible for site safety. This information is provided only as a service, and under no circumstances. should S&ME be assumed to be responsible for construction site safety. 4.10 Materials Testing During Construction Field evaluations and tesring will be very important during construction at this site so that the upper loose soil conditions are properly repaired to provide adequate support for the building slab and footings and pavements. A soils technician working; under the direction of the project Geotechnical Engineer should be present during subgrade preparation, fill placement and foundation installation. During the fill placement activities, a soils technician is recommended to perform field density tests to confirm compaction of fill soils is achieved. We recommend that foundation bearing surfaces be evaluated by the project Geotechnical Engineer or senior engineering; technician under his direction prior to concrete placement to confirm foundation bearing conditions assumed in design are available. 12 tS&ME Important information About Your Geotechnical Engineering Report Variations in subsurface conditions can be a principal cause of construction delays, cost overruns and claims. Ttk-1`ollowii�g information is provided to Assist you in understanding and managing the risk of these variations. Geotechnical Findings Are Professional Opinions Geotechnical engineers cannot specify material properties as other design engineers do. Geotechnical material properties have a tar broader range on a given site than any manufactured construction material, and some geotechnical material properties may change overtime because of exposure to air and water, or human activity. Site exploration identifies subsurface conditions at the time of exploration and only at the points where subsurface tests are performed or samples obtained. Geotechnical engineers review field and laboratory data and then apply their judgment to render professional opinions about site subsurface conditions. Their recommendations rely upon these professional opinions. Variations In the vertical and lateral extent of subsurface materials may be encountered during construction that significantly impact construction schedules, methods and material vclumes. While higher levels of subsurface exploration can mitigate the risk of encountering unanticipated subsurface conditions, no level of subsurface exploration can eliminate this risk. Scope of Geotechnical Services P rofessional geotechnical engineering judgment is required to develop a geotechnical exploration scope to obtain information necessary to support design and construction: A number of unique project factors are considered in developing the scope of geotechnical services, such as the exploration objective; the iocation, type, size and weight of the proposed structure; proposed site grades and improvements; the construction schedule and sequence; and the site geology. Geotechnical engineers apply their experience with construction methods, subsurface conditions and exploration methods to develop the exploration scope. The scope of each exploration is unique based on available project and site information. incomplete project information or constraints on the scope of exploration increases the risk of variations in subsurface conditions not being identified and addressed in the geotechnical report. Services Are Performed for Specific Projects Because the scope of each geotechnical exploration Is unique, each geotechnical report Is unique. Subsurface conditions are explored and recommendations are made for a specific project. Subsurface information and recommendations may not be adequate for other uses. Changes in a proposed structure location, foundation loads, grades, schedule. etc. may require additional geotechnical exploration, analyses, and consultation. The geotechnical engineer should be consulted to determine if additional services are required in response to changes in proposed construction, location, loads, grades, schedule. etc. Geo-Environmental Issues The equipment, techniques, and personnel used to perform a geo-environmental study differ significantly from those used for a geotechnical exploration, Indlcations of environmental contamination may be encountered incidental to performance of a geotechnical exploration but go unrecognized. Determination of the presence, type or extant of environmental contamination Is beyond the scope of a geotechnical exploration. Geotechnical Recommendations Are Not Final Recommendations are developed based an the geotechnical engineer's understanding of the proposed construction and professional opinion of site subsurface conditions. Observations and tests must be performed during construction to confirm subsurface conditions exposed by construction excavations are consistent with those assumed in development of recommendations. It is advisable to retain the geotechnical engineer that performed the exploration and developed the geotechnical recommendations to conduct tests and observations • during construction. This may reduce the risk that variations in subsurface conditions will not be addressed as recommended in the geotechnical reoort.

Box 53774 Fayetteville, NC 28305 Attention: Mr. Ron Williams, P.E. Reference: Soil Evaluation & Seasonal High Water Table (SHWT) Estimation Gray's Creek Medical Center 1-10pe Mills, Cumberland County, North Carolina SRME Project No. 1054-12-087 Dear Mr. Williams: S&ME, [tic. (S&MH) has conducted a soil evaluation including Seasonal High Water "fable (SI-IW-1) estimation in general accordance with S&ME Proposal No. 11044-12V dated February 24, 2012. Our evaluation was conducted to review the site and soil conditions for the conversion ofan existing temporary storimvater 13MP to a permanent wet detention basin. A soil scientist evaluated the soil conditions adjacent to the existing stormwatcr 13M1'. PROJECT BACKGROUND The Gray's Creek Medical Center is located at 1249 Chickenfoot Road, in Hope Mills, NC. The site location and proposed wet detention basin location is shown on the attached USGS "topographic Map (Figure 1), USDA-NRCS Cumberland County Soil Survey map (Figure 2). and Color Aerial Map (Figure 3). As it result of the construction and impervious surfaces, the use of a wet detention basin is currently being considered in Girder to comply with State storn-twater manaLelllent 1t(IllilClllellis. Use ofstorrllwater 13MP's are sub ect to the sultability of soils on -site and regulatory Approval. Regulatory guidance on recluiremeints filr permitting of stormwatcr RMP's are provided in the North Carolina Division of Water Quality — Stormwater Best Management Practices Manual (NCDI?NR-SW-I3MP), dated July 2007 (Revised September, 2009). FINDINGS The Soil CValliatiOn was periornled with hand auger borings at filar different locations adjacent to (lie existing temporary stormwatcr 13MP as shown on the attached Fit ure 4. Our evaluation consisted of identifying and recording the soil morphological conditions at those locations in order to develop soil profile descriptions, which are also shown on the attachcd Figure 4. SWE, INC. / 3201 Spring Forest Road 1 Raleigh, NC 27616 1 p 919.872.2660 1919.876.3956 / www.smeinc.com Soil Evaluation for Stormwater Wet Detention Basin S&ME Job No. 1054-12-087 Gray's Creek Medical Center, Hope Mills, North Carolina March 9, 2012 SHWT Estimation & OWT Measurement Under current NCDWQ regulations, the depth ofvarious stormwater BMP devices from the SI-IWT is an important design consideration. Current regulations for wet detention basins require that the permanent pool elevation shall be no more than six inches above or below the SHWT in order to maintain a permanent pool of water and to avoid doing a hydrogeologic analysis. Therefore, S&ME evaluated the SHWT by advancing hand auger borings and evaluating; the soil for evidence of SI-IWT influence. This evaluation involved looking at the actual moisture content in the soil and observing, the matrix and mottle colors. Depending; oil the soil texture, the soil color will indicate processes that are driven by SHWT fluctuations, such as iron reduction and oxidation and organic matter staining. Please note that these SI-IWT evaluations by soil indicators are based on secondary evidence and not on direct groundwater level measurements. In addition, S&ME recorded the observed water table (OWT) level where possible. '['he OWT was measured as the static water level in each of the temporary hand auger boring locations. See Table l and the soil profile descriptions on Figure =4 for tile estimated seasonal high water table depths based on soil saturation and measured OWT depths. It should be noted that the static water level/OWT measured in the auger holes is a measurement of the water table at that moment and does not represent in average water level or the highest point at which tile water table may rise to. Furthermore, it is expected that groundwater elevations in the study area will likely be influenced by factors such as precipitation, and proximity to surface water discharge/recharge features. Please note that Boring l was performed on top of the existing, fill material, not native soil, that was used to construct the berm ofthe existing temporary stormwater BMP and therelorc, we NVe1'e unable to estimale the SHWTat this location, however an observed water table (OWT) reading was provided for this location. In addition, Borings 1-3 all had soil characteristics that indicated a Si-IWT less than 12 inches from the natural ground surfitce and Boring d had ground water at the surface. Table I below shows the sviW I and UW r depths fronh existing grOLlnd level 601- the fOUr boring locations. Table 1: SHWT and OWT Information Boring Location SHWi_ inches below Existin� GroundLevel :.,(inches below Existing Ground Level) B-1 NIA 60 B-2 <12 12 B-3 <12 NIA B-4 0 0 Soil Evaluation for Stormwater Wet Detention Basin S&ME Job No. 1054-12-087 Gray's Creek Medical Center, Hope Mills, North Carolina March 9, 2012 CONCLUSION Based on our observations regarding; the SHWT' and OWT at the four boring locations, the permanent pool elevation of the wet detention basin should be +/- 6 inches from the existing ground level elevation located adjacent to the existing temporary stormwater BMP. LIMITATIONS • Data only from hand auger borings, where performed, and conditions may vary in other areas of the basin. • A significant amount ofcutting and tilling; across the site has resulted in the alteration of the soil conditions.

Typically, the surface layer is dark grayish brown loamy sand 4 inches thick. The subsurface layer is yellowish brown loamy sand 5 inches thick. The subsoil is 51 inches thick. The upper part is yellowish red sandy clay loam, the middle part is red sandy clay loam, and the lower part is yellowish red sandy clay loam, The underlying material to a depth of 73 inches is reddish yellow sandy loam. Permeability is moderately slow in the upper part of the subsoil and slow in the lower part. Reaction ranges from extremely acid through strongly acid in all horizons, except where the surface has been limed. The hazard of erosion is severe where the soil is exposed. Included with this soil in mapping are areas of a soil that is eroded and has a surface layer of gravelly loamy sand. Also included are more clayey Gilead soils and sandier Blaney and Candor soils. These included soils make up less than 20 percent of most mapped areas. Most areas of this soil are in woodland. A small acreage is in pasture or in cultivated crops. Vaucluse soil is poorly suited to growing cultivated crops. The main limitation is susceptibility to erosion. If this soil is used for row crops, such practices as minimum tillage, contour farming, striperopping, grassed waterways, crop residue management, and including grasses and legumes in the cropping system help to reduce runoff and to control erosion. This soil is suited to grasses and legumes for hay and pasture. Using this soil for pasture is a good way of controlling erosion. This soil is suited to loblolly pine. The dominant trees are loblolly pine, longleaf pine, white oak, and red oak. The main understory includes dogwood, sourwood, holly, and threeawn. This soil is suited to most urban and recreational uses. Slope is a limitation to building site development. Erosion from areas where the soil has been disturbed can be a problem. To help prevent this, vegetative cover must be established as soon after soil disturbance as possible. This soil has severe limitations for onsite sewage disposal. The restricting factors are slow permeability of the brittle layer in the subsoil and steepness of slope, This soil is in capability subclass IVe and woodland suitability group 3o. VgE—Vaucluse-Gilead loamy sands, 15 to 25 percent slopes. This map unit consists of areas of Vaucluse soil and Gilead soil on long, narrow side slopes of uplands. This unit is most extensive in the northern and western parts of Cumberland and Hoke Counties. Individual areas of this unit are long and narrow in shape and range from 5 acres to more than 40 acres in size. These two soils are so intricately mixed and so similar in use and management that they were not separated in mapping. This unit consists of about 40 Soil Survey percent Vaucluse soil, 35 percent Gilead soil, and 25 percent soils of minor extent. Typically. Vaucluse soil has a surface layer of dark grayish brown loamy sand 4 inches thick. The subsurface layer is yellowish brown loamy sand 5 inches thick. The subsoil is 51 inches thick. It is yellowish red sandy clay loam in the upper part, red sandy clay loam in the middle part, and yellowish red sandy clay loam in the lower part. The underlying material to a depth of 73 inches is reddish yellow sandy loam. Typically, Gilead soil has a surface layer of dark gray loamy sand 4 inches thick. The subsurface layer is light yellowlsh brown loamy sand 9 inches thick. The subsoil to a depth of 70 inches is brownish yellow sandy clay In the upper part; mottled strong brown, brownish yellow, and light gray sandy clay in the middle part; and reddish yellow sandy loam in the lower part. Permeability of Vaucluse and Gilead soils is moderately slow to slow. Available water capacity is low to medium. Reaction ranges from extremely acid through strongly acid in all horizons, except where the surface has been limed. The hazard of erosion is severe where the soil is exposed. A perched water table is above the brittle layers in the subsoil for brief periods during wet seasons. Included with these soils in mapping are small areas of sandier Blaney and Candor soils and small areas similar to Vaucluse and Gilead soils, except for the gravelly surface layer. Also included are small seep areas where water draining from the uplands comes to the surface. This unit has numerous areas where the soil mass has slipped downslope. This has exposed short, vertical walls consisting of massive, gray clay. These vertical faces typically are less than 15 feet high. Nearly all areas of this unit are in native woodland, mostly loblolly pine, oaks, and hickories. These soils are suited to hardwood and pine. The dominant trees are loblolly pine, longleaf pine, while oak, and southern red oak. The main understory includes dogwood, sourwood, holly, and threeawn. These soils are poorly suited to farming and to urban and recreational uses. Slope and slow permeability are the main limitations. These soils are in capability subclass Vie and woodland suitability group 3o. WaB--Wagram loamy sand, 0 to 6 percent slopes. This well drained soil is on broad, smooth flats and side slopes of uplands. It is throughout the survey area. Individual areas of this unit are irregular in shape and range from 5 to 300 acres in size. Typically, the surface layer is grayish brown loamy sand 8 inches thick. The subsurface layer is pale brown loamy sand 17 inches thick. The subsoil to a depth of 72 inches is yellowish brown sandy clay loam. Permeability is moderately rapid, and available water capacity is low to medium. Reaction is very strongly acid Cumberland and Hoke Counties, North Carolina or strongly acid throughout the soil, except where the surface has been limed. Included with this soil in mapping are small areas of sandier Autryville and Candor soils and Fuquay soils, which contain more than 5 percent plinthite in the subsoil. Also included are small areas of less sandy Norfolk and Faceviile soils and Goldsboro soils, which are wetter and less sandy. Typically, only two or three of these included soils are in any one mapped area, and they make up less than 20 percent of most delineations. Most areas of this soil are in cultivated crops. The rest are in pasture or woodland. Wagram soil is suited to cultivated crops, such as corn, soybeans, tobacco, and truck crops or to grasses and legumes for hay and pasture. If this soil is used for cultivated crops, minimum tillage, crop residue management, winter cover crops, and windbreaks can be used to control wind erosion, to reduce leaching of plant nutrients, and to conserve moisture. This soil is suited to loblolly pine, longleaf pine, white oak, southern red oak, and hickory. The main understory includes dogwood, sassafras, and waxmyrtle. This soil is well suited to most urban uses. Because of droughtiness, landscape management commonly includes frequent applications of fertilizer and irrigation water during long, dry periods. This soil is suited to most recreational uses. The thick, sandy surface layer can limit some types of recreational uses. This soil is in capability subclass lls and woodland suitability group 3s. WgB—Wagram-Urban land complex, 0 to 8 percent slopes. This map unit consists of areas of Wagram soil and areas of Urban land that are too small and too intermingled to be mapped separately. About 40 to 50 percent of the unit is Wagram soil and about 30 to 40 percent is Urban land. This map unit is most extensive in and around the city of Fayetteville. Mapped areas are 10 acres to more than 250 acres in size and are irregular in shape. Typically, Wagram soil has a surface layer of grayish brown loamy sand 8 inches thick. The subsurface layer is pale brown loamy sand 17 inches thick. The subsoil to a depth of 72 inches is yellowish brown sandy clay loam. Permeability is moderately rapid, and available water capacity is low to medium. Reaction is very strongly acid or strongly acid throughout the soil, except where the surface has been limed. Urban land consists of areas where the original soil has been covered by concrete, asphalt, buildings, or other impervious surfaces. Slope is modified to fit the site and commonly ranges from 0 to 4 percent. Included in this unit are small areas of Autryville and Candor soils, which are sandier than Wagram soil, and small areas of Norfolk and Faceville soils, which are less sandy than Wagram soil. Also included are small areas of Fuquay soils, which contain more than 5 percent EVA plinthite in the subsoil. Some delineations contain small areas of the wetter, less sandy Goldsboro soils, which usually are in small depressions. These included soils make up 10 to 20 percent of most mapped areas. Undeveloped areas of this soil are being converted to urban uses very rapidly. This map unit is well suited to most urban and recreational uses. Because of droughtiness, landscape management commonly includes frequent applications of fertilizer and irrigation water during long, dry periods. The thick, sandy surface layer can limit some types of recreational uses. This unit has not been assigned to a capability subclass or a woodland suitability group. WmB—Wickham fine sandy loam, t to 6 percent slopes. This well drained soil is on slightly convex ridges of stream terraces along the Cape Fear River, Lower Little River, and Rockfish Creek. This soil is in Cumberland County. Individual areas of this unit are generally long and narrow in shape and parallel to the stream channel. Mapped areas range from 5 to 50 acres in size. Typically, the surface layer is dark brown fine sandy loam 7 inches thick. The subsoil is 39 inches thick. It is red sandy clay loam in the upper part and yellowish red sandy loam in the lower part. The underlying material to a depth of 80 inches is yellowish red loamy sand in the upper part and strong brown sand in the lower part. Permeability is moderate, and available water capacity is medium. Reaction ranges from very strongly acid through medium acid in all horizons, except where the surface has been limed. The hazard of erosion is moderate. Wickham soil is subject to rare flooding. Included with this soil in mapping are small areas of sandier Tarboro soils; wetter Altavista soils; and wetter, more clayey Dogue, Roanoke, and Wahee soils. Tarboro soils are on higher ridges, Altavista and Dogue soils are in slight depressions, and Roanoke and Wahee soils are along drainageways. These included soils make up less than 20 percent of most mapped areas. Most areas of this soil are in cultivated crops or pasture, and the rest are mostly in woodland. A few small areas are urban. Wickham soil is well suited to growing cultivated crops, such as corn, soybeans, tobacco, and small grains, or to grasses and legumes for hay and pasture. Susceptibility to erosion is the main limitation. Minimum tillage, winter cover crops, striperopping, field borders, farming on the contour, and crop residue management help to reduce surface runoff and maintain tilth. The use of this soil for pasture maintains constant cover and is a good way to reduce erosion. This soil is well suited to hardwoods and pines. The dominant trees are loblolly pine, red maple, hickory, yellow -poplar, black tupelo, American elm, American beech, southern red oak, water oak, and white oak.
