Background This report contains the approach for a stormwater impact analysis conducted for the proposed PI 160 Birch Street Physical Fitness Center development. The project site is located at Marine Corps Base (MCB) Camp Lejeune in Onslow County, North Carolina. The proposed development is on approximately 25 acres and is bound by Birch Street to the south as shown in Figure I and Figure 2. The proposed project includes the development of a physical fitness center as shown in the attached plans, Appendix A. The proposed project has been design in accordance with LID implementation guidelines per current NAVFAC policy directive and USGBC LEED criteria. II. Existing Conditions The proposed project site is currently an undeveloped, wooded area with exception to an existing sidewalk, running parallel to Birch Street. A review of the topographic survey shows grades on the site ranging from approximately elevation 5 to elevation 20. The site generally has 0 to 6% slopes. According to Table 3-4 in the North Carolina Department of Environment and Natural Resources (NCDENR) Stormwater BMP Manual, the near surface soils in Onslow County are classified as Hydrologic Group B. A geotechnical investigation was completed in June 2010. An infiltration site visit was completed by Vincent Lewis of NCDENR in July 2010. The results of the geotechnical investigation and the infiltration site visit have been submitted with this package as Appendix B. III. Wetlands and Waters of the United States A wetland delineation of the proposed project area was completed by the United States Army Corps of Engineers on October 22, 2007. The Notification of Jurisdictional Determination is attached as Appendix C. No permanent impacts to wetlands are proposed for this project. Temporary impacts to wetlands associated with the installation of underground utilities, will be avoided through directional drilling. There are no Waters of the Unites States on the proposed project site. A 50ft setback from blue line streams to all built upon area was observed. In order to comply with USGBC LEED criteria, a 100ft buffer from field delineated wetlands to all impervious surfaces has been implemented in the site plan. IV. Proposed Development The proposed P1160 Camp Lejeune Physical Fitness Center includes the development of one fitness center building, two parking lots, a recreation trail, an artificial turf field, and associated access roads. The proposed project is on 25.03 acres. The post -development impervious area of the proposed development has been calculated to be approximately 7.54 acres or 30.10%. V. Stormwater Analysis Onslow County is a coastal county located within the White Oak River Basin. Thus, stormwater management measures have been designed in accordance with the Coastal Stormwater Rules Session Law 2008-211. The proposed project area drains to the Beaverdam Creek, Index Number: 19-20-1. According to North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Quality the proposed project drains to SB waters. The build upon area is greater than 24%; therefore, the project is considered High -Density. Camp Lejeune P1160 Birch Street Physical Fitness Center - August 2010 KHA Job ii 148136002 7 2010 c, Per the stormwater quality requirements, the first 1.5" of rain must be stored, controlled, and treated for 85% to 90% of the Total Suspended Solids (TSS). The temporary pool of wet detention ponds must drawdown between 48 and 120 hours. Per the stormwater quantity requirements, the storage volume must be discharged at a rate equal to or less than the pre -development discharge rate for the 1-year 24-hour storm. Additionally, discharge directed to flow through wetlands must do so at a non -erosive velocity. The calculations and supplemental forms submitted with this narrative demonstrate that the proposed project will meet all requirements of the Coastal Stormwater Rules Session Law 2008-21 1. The storm water management design proposes an integrated system of bioretention basins, pervious pavement, and two wet detention ponds to satisfy the LID implementation guidelines per current NAVFAC policy directive.Towever, because of specific soil and groundwater conditions encountered on the site the bioretention basins and pervious pavement will not be used toward credit to satisfy the State stormwater requirements. Therefore, the two wet ponds shown are designed to fully satisfy all State stormwater requirements and the permit request will be based exclusively on the two wet detention ponds VI. Design Procedure The limits of the study area were established by determining the areas contributing runoff to the site using available topographic information. The topographic map and wetland delineation illustrate that the entire site drains west, northwest to Beaverdam Creek, which outfalls into Wallace Creek Index Number: 19-20. Structural measures will be required for conveying and controlling increases in stormwater runoff directly related to the increase in impervious area due to the P 1160 Physical Fitness Center development. Although site specific soil and groundwater conditions do not allow for the accreditation of previous pavement, increases in impervious area have been minimized through use of pervious pavement in parking stalls and walkways. Additionally, clearing and grading are being held tight to the building and parking areas to preserve as much of the natural wooded area as practical. Runoff from rainfall events will be controlled by a series of drainage inlets and be conveyed using underground piping networks. Each of these networks will empty directly into one of two on -site wet detention ponds with forebays. The wet ponds located will outfall into unnamed ditches, which are tributaries to Beaverdam Creek, which outfalls into Wallace Creek Index Number: 19-20. The stormwater networks and basins will treat runoff from the entire built upon area, with exception to a small portion of the jogging trail located north of the physical fitness center building. The conservation of natural area to the top of the slope at the wetland buffer will serve as a densely vegetated and forest littered buffer strip for filtering and velocity dissipation of runoff from this portion of the trail to the wetlands. This northern loop of the jogging trail is noted as Drainage Area "T" in the permit application. The existing and proposed drainage systems have been evaluated for peak flow rates using ICPR software. ICPR utilizes SCS curve number methods of generating hydrographs. Rational Method (Q=CIA), Manning's Equation, and StormCAD software have been used in the design of the proposed stormwater system.

The construction at this site is planned to consist of building a 2-story Physical Fitness Center building of steel frame and load bearing CMU wall design supported on shallow foundations. At this time the conceptual site plans indicate that the building will have a footprint area of about 69,000 to 70,000 square feet. The construction at this site is also planned to consist of paved driveways and parking areas, underground utilities and other associated infrastructure components. Our field exploration program included five (5) 30-foot deep Standard Penetration Test (SPT) borings, drilled by G E T Solutions, Inc. within the footprint of the proposed structures. Additionally, four (4) 10-foot deep Standard Penetration Test (SPT) borings were drilled within the proposed pavement areas along with CBR testing.

The following evaluations and recommendations were developed based on our field exploration and laboratory -testing program: SEP 0 7 2010 GET Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G ■ Field testing program during construction to include, subgrade proofrolling, compaction testing, and foundation excavation observations for bearing capacity verification. All other applicable testing, inspections, and evaluations should be performed as indicated in the North Carolina State Building Code (2006 International Building Code with North Carolina Amendments). ■ An estimated cut depth of about 6 inches will be required to remove the topsoil and associated root mat from within the construction areas. • Some subgrade improvements should be anticipated within the construction areas (undercutting and backfilling with select fill) as a result of potentially soft/loose subgrade soils containing appreciable amounts of fines (silt and clay). • Expansion index testing completed on the shallow subsurface clays at the project site revealed a very low to low expansion portential. • Shallow foundations designed using a net allowable bearing capacity of 2,000 psf (24-inch embedment, 24-inch width). ■ Estimated post -construction total and differential settlements up to 1-inch and 1/2- inch, respectively. • The foundations should also be designed with the use of top and bottom reinforcing steel for added rigidity and to increase the foundation performance with respect to settlement. • Concrete Masonry Unit wall construction should be designed to contain construction joints at on -center distances not exceeding 25 feet. These joints will provide for more flexible wall members that are less likely to crack as a result of settlement. • It is noted that, in accordance with the NC Building Code; Chapter 16, this site is classified as a site Class D, based on which seismic designs should be incorporated. This recommendation is based on the data obtained from the completed SPT borings as well as our experience with shear wave velocity testing performed on projects within the vicinity of the site. • Pavement sections to be designed using a CBR value of about 7.2, typical Pavement sections are provided in the body of the report. This summary briefly discusses some of the major topics mentioned in the attached report. Accordingly, this report should be read in its entirety to thoroughly evaluate the contents.

Authorization to proceed with the services was provided by Keith Tricome of Suffolk Construction Company, Inc. 1.2 Project Description The construction at this site is planned to consist of building a 2-story Physical Fitness Center building of steel frame and load bearing CMU wall design supported on shallow foundations. At this time the conceptual site plans indicate that the building will have a footprint area of about 69,000 to 70,000 square feet. The maximum wall and column foundation loads associated with the structure were not known at the time of this report. However, based on our experience with similar projects, the maximum wall loads associated with the building are not expected to exceed 6 kips per linear foot, and the column loads are not expected to exceed 150 kips. The structure's first floor will be supported on -grade with the distributed loads estimated at 150 pounds per square foot. The structure's first floor elevation is expected to be located at about 20.5 feet MSL. The existing site grade elevations within the proposed construction area of the site were generally noted to range from about 15 to 20 feet MSL. Accordingly, cut and fill operations necessary to establish the design grade elevations are not anticipated to exceed about 5 feet. The construction at this site is also planned to consist of paved driveways and parking areas, underground utilities and other associated infrastructure components. If any of the noted information is incorrect or has changed, please inform G E T Solutions, Inc. so that we may amend the recommendations presented in this report, if appropriate. 1.3 Purpose and Scope of Services The purpose of this study was to obtain information on the general subsurface conditions at the proposed project site. The subsurface conditions encountered were then evaluated with respect to the available project characteristics. In this regard, engineering assessments for the following items were formulated: 1. General assessment of the soils revealed by the borings performed at the proposed development.

In addition, an evaluation of the shrink/swell characteristics of the shallow Clay soils present at the site was conducted (expansion index testing) and their effect upon the development is provided. Soil subgrade preparation, including stripping, grading and compaction. Engineering criteria for placement and compaction of approved structural fill material. 4. Construction considerations for fill placement, subgrade preparation, and foundation excavations. 5. Feasibility of utilizing a shallow foundation system for support of the proposed structure. Design parameters required for the foundation system, including foundation sizes, allowable bearing pressures, foundation levels and expected total and differential settlements. 6. Typical pavement sections based on the field exploration activities (4 CBR tests and associated borings) and our experience with similar soil conditions. The scope of services did not include an environmental assessment for determining the presence or absence of wetlands or hazardous or toxic material in the soil, bedrock, surface water, groundwater or air, on or below or around this site. Prior to development of this site, an environmental assessment is advisable. 2.0 FIELD AND LABORATORY PROCEDURES 2.1 Field Exploration In order to explore the general subsurface soil types and to aid in developing associated foundation parameters, five (5) 30-foot deep SPT borings (designated as B-1 through B-5) were drilled within the proposed structure's footprint. In order to explore the general subsurface soil types and to aid in developing associated pavement design parameters, four (4) 10-foot deep Standard Penetration Test (SPT) borings (designated as P-1 through PA) were drilled within the proposed parking and driveway areas. To aid in developing associated storm water management parameters, two borings and two (2) saturated hydraulic conductivity tests (in -situ) were proposed to be completed within the proposed stormwater management pond. However, at the time of our subsurface exploration procedures, the proposed storm water management pond area had not been determined. Therefore, this testing was not performed. r � d 7 2010 Solutiodsl'1nc� '�,�?� Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G The SPT borings were performed with the use of rotary wash "mud" drilling procedures in general accordance with ASTM D 1586. The tests were performed continuously from the existing ground surface to a depth of 12-feet, and at 5-foot intervals thereafter. The soil samples were obtained with a standard 1.4" I.D., 2" O.D., 30" long split -spoon sampler. The sampler was driven with blows of a 140 lb. hammer falling 30 inches, using an automatic hammer. The number of blows required to drive the sampler each 6-inch increment of penetration was recorded and is shown on the boring logs. The sum of the second and third penetration increments is termed the SPT N-value (uncorrected for automatic hammer). A representative portion of each disturbed split -spoon sample was collected with each SPT, placed in a glass jar, sealed, labeled, and returned to our laboratory for review. Four (4). bulk soil samples, designated as CBR-1 through CBR-4, were collected from the proposed pavement areas at the location of borings P-1 through P-4, respectively. The bulk subgrade soil samples were collected from depths ranging from 0.25 to 1 foot below existing grades. The bulk soil samples were returned to our laboratory and subjected to CBR testing in accordance with ASTM standards. Two (2) thin -walled tube samples were obtained from the shallow CLAY stratum, by hydraulically pressing a 3-inch outside diameter Shelby tube into the soils. Specifically the tube samples were obtained at the location of borings B-1 and B-3 at a depth of 2 to 4 feet below the existing site grades. The tubes were sealed to prevent moisture loss and returned to the laboratory for extraction, classification and expansion index testing. The boring locations were established and staked in the field by a representative of G E T Solutions, Inc. with the use of a Global Positions System unit as well as the "State Plane" coordinates selected from the project site plan. The approximate boring locations are shown on the attached "Boring Location Plan" (Appendix 1), which was reproduced based on the site plan provided by Kimley-Horn and Associates, Inc. 2.2 Laboratory Testing Representative portions of all soil samples collected during drilling were sealed in glass jars, labeled and transferred to our laboratory for classification and analysis. The soil classification was performed by a Geotechnical Engineer in accordance with ASTM D2488. Four (4) representative soil samples were selected and subjected to laboratory testing, which included natural moisture, 4200 sieve wash and Atterberg Limit testing and analysis, in order to corroborate the visual classification. These test results are provided in Table I on the following page and are presented on the "Boring Log" sheets (Appendix II), included with this report. 3 SEP 0 7 2010 Solutlon5,71nc, , �; Report of Subsurface Investigation and Geotechnical Engineering Services P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G Table I - Laboratory Test Results June 16, 2010 " " "Natural' �� %'" Atterberg -' °�+•USCS ,', ' Bormg ,,, No ;Depth (Feet)If 'Moisturre = Passing . `L'-imits ..Classificatio ^�i •�; tt .t, f, , t % 4 #200 (LL/ L/PPI) n B-2 8-10 17.6 14.4 Non Plastic SM B-2 10-12 6.0 7.9 Non Plastic SP-SM B-3 13-15 21.9 14.7 Non Plastic SM B-4 10-12 21.8 17.84 Non Plastic SM In addition, selected soil samples from the collected Shelby tubes were subjected to expansion index, 4200 sieve wash and Atterberg Limit testing and analysis to evaluate the shrink/swell characteristics of the shallow on -site Clay soils.

This site consists predominantly of a heavily wooded parcel. The proposed construction areas are bordered to the south by Birch Street followed by a heavily wooded area, and to the north, east and west by a wooded area. A small unnamed creek meanders along the northern and western boundary of the site. SEP 0 7 2010 GET Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G 3.2 Subsurface Soil Conditions The results of our soil test borings indicated the presence of approximately 1 to 4 inches of topsoil at the boring locations. Underlying the topsoil the remaining subsurface soils recovered at the boring locations were generally uniform and consistent to the explored depths and noted to be arranged in a three -layer configuration. The initial soil layer underlying the topsoil at the boring locations extended to a depth of approximately 2 feet below existing grades and was noted to be primarily granular in nature consisting of SAND (SM) with varying amounts of silt and/or clay. As an exception, a deposit of medium stiff Sandy SILT (ML) was encountered at boring P-4. The Standard Penetration Test (SPT) results, N-values, recorded within this initial granular soil layer ranged from 4 to 10 blows -per -foot (BPF) indicating a very loose to loose relative density. The second soil layer extended beneath the initial soil layer to approximate depths of 8 feet to 10 feet below existing site grades. The recovered soils were classified as Sandy CLAY (CL). As an exception, this layer was not encountered at boring P-4 location. The Standard Penetration Test (SPT) results, N-values, recorded within this soil layer ranged from 5 to 16 blows -per -foot (BPF) indicating a medium stiff to very stiff consistency. The final soil layer extended beneath the second soil layer to approximate depths of 10 to 30 feet below existing site grades (boring termination depths) where the recovered soils were classified as SAND (SM and SP-SM) with varying amounts of silt. As an exception, this layer was not encountered at boring P-1 and P-2 locations. The Standard Penetration Test (SPT) results, N-values, recorded within this soil layer ranged from 5 to 39 blows -per - foot (BPF) indicating a loose to dense relative density. The subsurface description is of a generalized nature provided to highlight the major soil strata encountered. The records of the subsurface exploration are included on the "Boring Log" sheets (Appendix II) and in the "Generalized Soil Profile" (Appendix III), which should be reviewed for specific information as to the individual borings. The stratifications shown on the records of the subsurface exploration represent the conditions only at the actual boring locations. Variations may occur and should be expected between boring locations. The stratifications represent the approximate boundary between subsurface materials and the transition may be gradual or occur between sample intervals. It is noted that the topsoil designation references the presence of surficial organic laden soil, and does not represent any particular quality specification. This material is to be tested for approval prior to use. 7,��PO 2010 Solution§; Inc , -..-i Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G 3.3 Shrink -Swell Characteristics: The Clayey soils recovered during our field exploration were evaluated for their potential to expand or contract with moisture changes (typically termed shrink -swell). Shallow foundations constructed on these clays at certain depths may be subjected to detrimental uplift forces caused by the swelling of these soils as a result of an increase in the moisture content. Conversely, as these clays lose moisture they may shrink resulting in excessive settlements. This situation can adversely affect the foundation. The most important fact to remember is that swelling and shrinking will only take place if moisture changes occur, which can be induced by change in weather conditions, leaky pipes, poor drainage and site layout (i.e. reduction of trees, elevation change etc.). The depth of the soil influenced by weather conditions is termed the "active depth", which will vary due to weather changes, locality and the presence or absence of ground water. Soils encountered below the active zone may posses the characteristics for potential shrink/swell, but since the water content of the soil is constant, volume changes will not take place. The local active depth associated with the change in weather conditions generally extends to about 4 to 10 feet below existing grades depending on the region, and site topography. Many researchers have developed relationships between the shrink/swell potential and various soil properties. Liquid Limit (LL) and Plasticity Index (PI) testing are commonly used as indicators of shrink/swell potential, ,with the higher Pi's resulting in higher shrink/swell potential. Several publications recognize soils with Pi's in excess of 25 as high potential shrink/swell soils, conversely soils with Pi's less than 15 are considered to be of low shrink/swell potential. Another indicator to consider when evaluating the shrink/swell potential is the fines (Silt/Clay) content. The greater the fines content the more susceptible the soil is to moisture changes. Alternatively, plastic soils containing greater than 25%to 30% Sand by weight are not as likely to experience significant volume changes even though the Plasticity Index (PI) may indicate otherwise. Furthermore, the local USDA Soil Surveys and the soil mineralogy are also used as an indicator of shrink/swell potential. In order to further qualify the expansion potential of these soils, the definition presented in ASTM D-4829-95 test method may be utilized, where the following criteria are provided: Expansion Index (EI) Potential Expansion 0-20 Very Low 21-50 Low 51-90 Medium 91-130 High >130 Very High 6 SEP 0 7 2010 I GET Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G 3.4 On -Site Soil Properties: Based on the visual and laboratory classification (Sand content of 62% to 68%, PI's 10 to 17, Expansion Index of 17), the soils encountered at the boring locations to depths of 2 to 4 feet below existing grades are considered to have low shrink/swell potential. Accordingly, foundation improvements will not be required to accommodate shrink/swell concerns. 3.5 Groundwater Information The groundwater level was recorded at the location of borings B-1 through B-5 and as observed through the wetness of the recovered soil samples during the drilling operations. The initial groundwater table encountered at these boring locations was measured to occur at depths ranging from 11.5 to 13 feet below current grades, which corresponds to an elevation ranging from about 5.5 feet to 6 feet (MSQ. The groundwater level was not encountered to the explored depths of 10 feet below the existing site grade elevations at borings P-1 through P-4. The boreholes were backfilled upon completion for safety considerations. As such, the reported groundwater levels may not be indicative of the static groundwater level. Groundwater conditions will vary with environmental variations and seasonal conditions, such as the frequency and magnitude of rainfall patterns, as well as man-made influences, such as existing swales, drainage ponds, underdrains and areas of covered soil (paved parking lots, sidewalks, etc.). Seasonal groundwater fluctuations of ± 2 feet are common in the project's area; however, greater fluctuations have been documented. We recommend that the contractor determine the actual groundwater levels at the time of the construction to determine groundwater impact on the construction procedures. 4.0 EVALUATIONS AND RECOMMENDATIONS Our recommendations are based on the previously discussed project information, our interpretation of the soil test borings and laboratory data, and our observations during our site reconnaissance. If the proposed construction should vary from what was described, we request the opportunity to review our recommendations and make any necessary changes. 4.1 Clearing and Grading The proposed construction area should be cleared by means of removing the topsoil, trees, and associated root mat. It is estimated that a cut of up to 6 inches in depth will be required to remove the topsoil. This cut is expected to extend deeper in isolated areas to remove deeper deposits of organic soils, or unsuitable soils, which become evident during the clearing. It is recommended that the clearing operations extend laterally at least 5 feet beyond the perimeter of the proposed construction areas. SEP 0 7 2010 Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G Following the initial clearing, the resulting exposed subgrade will generally be comprised of SAND (SM) and SILT (ML) containing an appreciable amount of fines (silt and clay). Accordingly, combinations of excess surface moisture from precipitation ponding on the site and the construction traffic, including heavy compaction equipment, may create pumping and general deterioration of the bearing capabilities of the surface soils. Therefore, undercutting to remove loose soils in isolated areas should be expected. The extent of the undercut will be determined in the field during construction based on the outcome of the field testing procedures (subgrade proofroll). In this regard, and in order to reduce undercutting, care should be exercised during the grading and construction operations at the site. Furthermore, inherently wet subgrade soils combined with potential poor site drainage make this site particularly susceptible to subgrade deterioration. Thus, grading should be performed during a dry season if at all possible. This should minimize these potential problems, although they may not be eliminated. The project's budget should include an allowance for subgrade improvements (undercut and backfill with structural fill or aggregate base in the building and pavement areas). 4.2 Subgrade Preparation Following the clearing operation, the exposed subgrade soils should be densified with a large static drum roller. After the subgrade soils have been densified, they should be evaluated by G E T Solutions, Inc. for stability. Accordingly, the subgrade soils should be proofrolled to check for pockets of loose material hidden beneath a crust of better soil. Several passes should be made by a large rubber -tired roller or loaded dump truck over the construction areas, with the successive passes aligned perpendicularly. The number of passes will be determined in the field by the Geotechnical Engineer depending on the soils conditions. Any pumping and unstable areas observed during proofrolling (beyond the initial cut) should be undercut and/or stabilized at the directions of the Geotechnical Engineer. Following the proofroll and approval by the engineer, it is recommended that the newly exposed subgrade soils be compacted to a dry density of at least 95 percent of the Modified Proctor maximum dry density (ASTM D1557), as tested to a depth of at least 12 inches. 4.3 Structural Fill and Placement Following the approval of the natural subgrade soils by the Geotechnical Engineer, the placement of the fill required to establish the design grades may begin. Any material to be used for structural fill should be evaluated and tested by G E T Solutions, Inc. prior to placement to determine if they are suitable for the intended use. Suitable structural fill material should consist of sand or gravel containing less than 20% by weight of fines (SP, SP-SM, SM, SW, SW-SM, GP, GP-SM, GW, GW-SM), having a liquid limit less than 20 and plastic limit less than 6, and should be free of rubble, organics, clay, debris and other unsuitable material. 8 SEP 0 7 2010 GET Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G The Silty SAND (SM) and SAND (SP-SM) subsurface soils encountered at the boring locations appear to meet the criteria recommended in this report for reuse as structural fill. Further classification testing (natural moisture content, gradation analysis, and Proctor testing) should be performed in the field during construction to evaluate the suitability of excavated soils for reuse as fill within building and pavement areas. The remaining on -site excavated soils (Topsoil, SILT and CLAY) are not anticipated to be suitable for re -use as structural fill but may be used as fill within green areas. All structural fill should be compacted to a dry density of at least 95 percent of the Modified Proctor maximum dry density (ASTM D1557). In general, the compaction should be accomplished by placing the fill in maximum 10-inch loose lifts and mechanically compacting each lift to at least the specified minimum dry density. A representative of G E T Solutions, Inc. should perform field density tests on each lift as necessary to assure that adequate compaction is achieved. Backfill material in utility trenches within the construction areas should consist of structural fill (as previously above), and should be compacted to at least 95 percent of ASTM D1557. This fill should be placed in 4 to 6 inch loose lifts when hand compaction equipment is used. Care should be used when operating the compactors near existing structures to avoid transmission of the vibrations that could cause settlement damage or disturb occupants. In this regard, it is recommended that the vibratory roller remain at least 25 feet away from existing structures; these areas should be compacted with small, hand -operated compaction equipment. 4.4 Shallow Foundation Design Recommendations Provided that the construction procedures are properly performed, the proposed structure can be supported by shallow spread footings bearing upon firm natural soil or well compacted structural fill material. The footings can be designed using a net allowable soil pressure of 2,000 pounds per square foot (psf). In using net pressures, the weight of the footings and backfill over the footings, including the weight of the floor slab, need not be considered. Hence, only loads applied at or above the finished floor need to be used for dimensioning the footings. In order to develop the recommended bearing capacity of 2,000 pounds per square foot (pso, the base of the footings should have an embedment of at least 24 inches beneath finished grades and wall footings should have a minimum width of 24 inches. In addition, isolated square column footings are recommended to be a minimum of 3 feet by 3 feet in area for bearing capacity consideration. The recommended 24-inch footing embedment is considered sufficient to provide adequate cover against frost penetration to the bearing soils. 9 i SEP 0 7 2010 i Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G 4.5 Settlements It is estimated that, with proper site preparation including the subsurface improvements noted above (where required), the maximum resulting post construction total settlement of the proposed building foundations should be up to 1 inch, as contributed by the foundation bearing soils. The maximum differential settlement magnitude is expected to be less than 1/2 -inch between adjacent footings (wall footings and column footings of widely varying loading conditions), as contributed by the foundation bearing soils. The settlements were estimated on the basis of the results of the SPT borings. Careful field control will contribute substantially towards minimizing the settlements. 4.6 Foundation Excavations In preparation for shallow foundation support, the footing excavations should extend into firm natural soil or well compacted structural fill. All foundation excavations should be observed by G E T Solutions, Inc. At that time, the Geotechnical Engineer should also explore the extent of excessively loose, soft, or otherwise unsuitable material within the exposed excavations. Also, at the time of footing observations, the Geotechnical Engineer may find it necessary to make hand auger borings or use a hand penetration device in the bases of the foundation excavations. If pockets of unsuitable soils requiring undercut are encountered in the footing excavations, the proposed footing elevation should be re-established by means of backfilling with "flowable fill", concrete, or a suitable structural fill material compacted to a dry density of at least 95 percent of the Modified Proctor maximum dry density (ASTM D 1557), as described in Section 4.3 of this report, prior to concrete placement. This construction procedure will provide for a net allowable bearing capacity of 2,000 psf. Immediately prior to reinforcing steel placement, it is suggested that the bearing surfaces of all footings be compacted using hand operated mechanical tampers, to a dry density of at least 95% of the Modified Proctor maximum dry density (ASTM D 1557) as tested to a depth of 12 inches, for bearing capacity considerations. In this manner, any localized areas, which have been loosened by excavation operations, should be adequately recompacted. The compaction testing in the base of the footings may be waived by the Geotechnical Engineer, where firm bearing soils are observed during the footing inspections. Soils exposed in the bases of all satisfactory foundation excavations should be protected against any detrimental change in condition such as from physical disturbance, rain or frost. Surface run-off water should be drained away from the excavations and not be allowed to pond. If possible, all footing concrete should be placed the same day the excavation is made. If this is not possible, the footing excavations should be adequately protected. 10 I SEP 0 � 2010 J Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G 4.7 CMU Wall Construction Joints and Foundation Reinforcement: In order to further reduce the effect of any potential settlements upon the partial height CMU and brick walls, it is recommended that construction joints be implemented at on - center distances not exceeding 25 feet. These joints will provide for more flexible wall members that are less likely to crack as a result of any settlement. In order to provide a more rigid foundation system, more tolerant to the anticipated differential settlements, the wall footings should be designed with top and bottom steel reinforcement and stirrups. This approach will permit the footings to more effectively bridge over soft areas, minimizing the potential for foundation cracking. Column footings should also have top and bottom steel reinforcement. 4.8 Floor Slabs The floor slab may be constructed as a slab -on -grade member provided the previously recommended earthwork activities and evaluations are carried out properly. It is recommended that the ground floor slab be directly supported by at least a 4-inch layer of relatively clean, compacted, poorly graded sand (SIP) or gravel (GP) with less than 5% passing the No. 200 Sieve (0.074 mm). The purpose of the 4-inch layer is to act as a capillary barrier and equalize moisture conditions beneath the slab. It is recommended that all ground floor slabs be "floating". That is, generally ground supported and not rigidly connected to walls or foundations. This is to minimize the possibility of cracking and displacement of the floor slabs because of differential movements between the slab and the foundation. It is also recommended that the floor slab bearing soils be covered by a vapor barrier or retarder in order to minimize the potential for floor dampness, which can affect the performance of glued tile and carpet. Generally, use a vapor retarder for minimal vapor resistance protection below the slab on grade. When floor finishes, site conditions or other considerations require greater vapor resistance protection; consideration should be given to using a vapor barrier. Selection of a vapor retarder or barrier should be made by the Architect based on project requirements. 4.9 Seismic Design Recommendations: It is noted that, in accordance with the NC Building Code; Chapter 16, this site may be classified as a site Class D, based on which seismic designs should be incorporated. This recommendation is based on the data obtained from the SPT borings as well as our experience with shear wave velocity testing performed on projects within the vicinity of the site. - -- ---- 1 11 �tP 0 7 2010 I GET Report of Subsurface Investigation and Geotechnical Engineering Services P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G 4.10 Pavement Design June16,2010 The California Bearing Ratio (CBR) test results indicated an average soaked CBR value of 10.8. The average soaked CBR value was multiplied by a factor of two-thirds to determine a pavement design CBR value. The two-thirds factor provides the necessary safety margins to compensate for some non -uniformity of the soil. Therefore, a CBR value of 7.2 should be used in designing the pavement sections. The typical pavement sections provided in the following table are based on the results of our laboratory CBR testing, field explorations, and experience with similar soils conditions. Furthermore, these typical sections do not represent a completed pavement design in accordance with the UFC or NCDOT requirements and are considered to be preliminary.

Actual pavement section thickness should be provided by the design civil engineer based on traffic loads, volume, and the owners design life requirements. The above sections correspond to thickness representative of typical local construction practices and as such periodic maintenance should be anticipated. All pavement material and construction procedures should conform to United Facilities Command (UFC) and/or North Carolina Department of Transportation (NCDOT) requirements. Following pavement rough grading operations, the exposed subgrade should be observed under proofrolling. This proofrolling should be accomplished with a fully loaded dump truck or 7 to 10 ton drum roller to check for pockets of soft material hidden beneath a thin crust of better soil. Any unsuitable materials thus exposed should be removed and replaced with a well -compacted material. The inspection of these phases should be performed by the Geotechnical Engineer or his representative. The subgrade soils are likely to be unstable at the time of construction and some ground improvements are likely. As such, the project's budget should include a contingency to accommodate the potential ground improvements. 12 SEP 0 7 2010 Solutioics Inc.

These alternates are to be addressed by the Geotechnical Engineer during construction, if necessary, who will recommend the most economical approach at the time. 4.11 Soil Permeability At the time of our subsurface exploration procedures, the proposed storm water management pond area had not been determined. Therefore, this testing was not performed. Soil permeability testing can be performed once the stormwater pond areas have been determined. The results of this testing can be provided as an addendum to this report. 5.0 CONSTRUCTION CONSIDERATIONS 5.1 Drainage and Groundwater Concerns It is expected that dewatering may be required for excavations that extend near or below the existing groundwater table. Dewatering above the groundwater level could probably be accomplished by pumping from sumps. Dewatering at depths below the groundwater level may require well pointing. It would be advantageous to construct all fills early in the construction. If this is not accomplished, disturbance of the existing site drainage could result in collection of surface water in some areas, thus rendering these areas wet and very loose. Temporary drainage ditches should be employed by the contractor to accentuate drainage during construction. If water collects in foundation excavations, it will be necessary to remove water from the excavations, remove saturated soils, and re -test the adequacy of the bearing surface soils to support the design bearing pressure prior to concrete placement. 5.2 Site Utility Installation The base of the utility trenches should be observed by a qualified inspector prior to the pipe and structure placements to verify the suitability of the bearing soils. If unstable bearing soils are encountered during installation some form of stabilization may be required to provide suitable bedding. This stabilization is typically accomplished by providing additional bedding materials (NCDOT No. 57 stone). In addition, depending on the depth of the utility trench excavation, some means of dewatering may be required to facilitate the utility installation and associated backfilling. All utility excavations should be backfilled with structural fill, as described in Section 4.3 of this report. _--� CEP 0 7 2010 I 13 GET Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P•1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G 5.3 Excavations In Federal Register, Volume 54, No. 209 (October, 1989), the United States Department of Labor, Occupational Safety and Health Administration (OSHA) amended its "Construction Standards for Excavations, 29 CFR, part 1926, Subpart P". This document was issued to better insure the safety of workmen entering trenches or excavations. It is mandated by this federal regulation that all excavations, whether they be utility trenches, basement excavation or footing excavations, be constructed in accordance with the new (OSHA) guidelines. It is our understanding that these regulations are being strictly enforced and if they are not closely followed, the owner and the contractor could be liable for substantial penalties. The contractor is solely responsible for designing and constructing stable, temporary excavations and should shore, slope, or bench the sides of the excavations as required to maintain stability of both the excavation sides and bottom. The contractor's responsible person, as defined in 29 CFR Part 1926, should evaluate the soil exposed in the excavations as part of the contractor's safety procedures. In no case should slope height, slope inclination, or excavation depth, including utility trench excavation depth, exceed those specified in local, state, and federal safety regulations. We are providing this information solely as a service to our client. G E T Solutions, Inc. is not assuming responsibility for construction site safety or the contractor's activities; such responsibility is not being implied and should not be inferred. 6.0 REPORT LIMITATIONS The recommendations submitted are based on the available soil information obtained by G E T Solutions, Inc. and the information supplied by the client and their consultants for the proposed project. If there are any revisions to the plans for this project or if deviations from the subsurface conditions noted in this report are encountered during construction, G E T Solutions, Inc. should be notified immediately to determine if changes in the foundation recommendations are required. If G E T Solutions, Inc. is not retained to perform these functions, G E T Solutions, Inc. can not be responsible for the impact of those conditions on the geotechnical recommendations for the project. The Geotechnical Engineer warrants that the findings, recommendations, specifications or professional advice contained herein have been made in accordance with generally accepted professional geotechnical engineering practices in the local area. No other warranties are implied or expressed.

Following the substantial completion of our original subsurface exploration procedures and Geotechnical Engineering analysis, the proposed infiltration basin locations were provided to G E T Solutions, Inc. Accordingly, the purpose of this addendum is to provide permeability (infiltration) values based on the results of Saturated Hydraulic Conductivity Testing as well as our experience with similar soil conditions. Storm Water Infiltration Areas To aid in developing associated storm water management parameters, ten (10) hand auger borings (designated as S-1 through S-6 and S-9 through S-12) and ten (10) saturated hydraulic conductivity tests (in -situ) were completed within the proposed stormwater management areas located throughout the project site. The tests were performed at depths ranging from about 2 to 9 feet below current grades. The boreholes were prepared utilizing an auger to remove soil clippings from the base. The results of the borings are presented in Appendices II and III of this report, which corroborate the stratigraphy depicted by the original study. We have also provided the logs and profile from the June 16, 2010 report. The approximate boring locations are shown on the attached "Boring Location Plan" (Appendix 1), which was reproduced based on the site plan provided by Kimley-Horn and Associates, Inc. Infiltration testing was then conducted within the vadose zone utilizing a Precision Permeameter and the following testing procedures. 415-A Weslmn Boulevard • Jacksonville, NC 25546 • Phonc (910) 478-9915 • Fax: (910) 478 -9917 info @ygelsoltil ionsinacom Report of Subsurface Investigation and Geotechnical Engineering Services June 29, 2010 P-1160 Physical Fitness Center MCB Camp LeJeune, North Carolina GET Project No: JX10-103G Addendum No.1 A support stand was assembled and placed adjacent to each borehole. This stand holds a calibrated reservoir (2000 ml) and a cable used to raise and lower the water control unit (WCU). The WCU establishes a constant water head within the borehole during testing by use of a precision valve and float assembly. The WCU was attached to the flow reservoir with a 2-meter (6.6 foot) braided PVC hose and then lowered by cable into the borehole to the test depth elevation. As required by the Glover solution, the WCU was suspended above the bottom of the borehole at an elevation of approximately 5 times the borehole diameter. The shut-off valve was then opened allowing water to pass through the WCU to fill the borehole to the constant water level elevation. The absorption rate slowed as the soil voids became filled and an equilibrium developed as a wetting bulb developed around the borehole. Water was continuously added until the flow rate stabilized. The reservoir was then re -filled in order to begin testing. During testing, as the water drained into the borehole and surrounding soils, the water level within the calibrated reservoir was recorded as well as the elapsed time during each interval. The test was continued until relatively consistent flow rates were documented. During testing the quick release connections and shutoff valve were monitored to ensure that no leakage occurred. The flow rate (0), height of the constant water level (H), and borehole diameter (D) were used to calculate Ks utilizing the Glover Solution. Based on the field testing and corroborated with laboratory testing results (published values compared to classification results), the hydraulic conductivity of the shallow soils was calculated to be as follows: Table II - Saturated Hydraulic Conductivity Test Results T,estNo .

The initial groundwater table encountered at these boring locations was measured to occur at depths ranging from 11.5 to 13 feet below current grades, which corresponds to an elevation ranging from about 5.5 feet to 6 feet mean sea level (MSL). The groundwater level was not encountered to the explored depths ranging from 4 to 10 feet below the existing site grade elevations at borings P-1 through P-4, S-1 through S-6 and S-9 through S-12. It is anticipated that a perched water condition may exist above a restrictive horizon (CLAY, CL) encountered at the boring locations with the exception of boring P-4 where this strata was not encountered. Color changes in this stratum from a mottled orangish brown -gray to a mottled gray-orangish brown Sandy CLAY (CL) were observed from depths ranging from approximately 3.5 to 4 feet below existing site grades: This gray color change is likely a result of the perched condition which may have affected this stratum during heavy precipitation events. Therefore, based on our drilling and soil classification program, the estimated seasonal high water table (SHWT) was determined to be below this restrictive CLAY (CL) layer and within the tan and brown SAND stratum which was encountered from about 8 to 10 feet below existing grades or about 7 to 11 feet MSL across the site. Groundwater conditions will vary with environmental variations and seasonal conditions, such as the frequency and magnitude of rainfall patterns, as well as man-made influences, such as existing swales, drainage ponds, underdrains and areas of covered soil (paved parking lots, sidewalks, etc.). Seasonal groundwater fluctuations of±2 feet are common in the project's area; however, greater fluctuations have been documented. We recommend that the contractor determine the actual groundwater levels at the time of the construction to determine groundwater impact on the construction procedures.

I have attached a sketch showing the proposed development conditions for your use and consideration of the request below. As we discussed, the SWM design proposes a system of integrated bioretention basins and wet pond BMP's to satisfy SWM requirements. However, because of specific soil and groundwater conditions encountered on the site in the area of the proposed bioretention basins they will not be used towards credit to satisfy the SWM requirements with the State, but will satisfy the LID implementation guidelines per current NAVFAC policy directive, and at the same time, will serve to augment the treatment of runoff from a major portion of the impervious areas on the site. The wet ponds shown are sized to fully satisfy the SWM requirements in compliance with the State's design guidelines, and are what the permit request will be based on. As you can see from the sketch, every attempt is being made to assimilate the ponds and the adjacent jogging trail into the natural contours of the site to provide an additional amenity to the users of the facility and a more pleasing appearance to the pond! s in light of their function. Clearing and grading are being held tight to the building and parking areas to preserve as much of the natural wooded area as practical. The portion of the 5ft wide jogging trail on this project is part of a system of trails that are connected throughout this area of Camp Lejeune for recreation by the civilian population of base residents, employees and military dependents, and are at times used to supplement physical training routines for U.S. Marines stationed at the base. The new Regimental Battalion complex to the north of this site is master planned to someday connect to this site's trail in the future, but this connection will not be a part of this permit. The heavy use of the trail(s) require a durable material for its construction, i.e. asphalt, rubberized track paving, or similar material for sustainability and ease of maintenance. z R . Additionally, to comply with USGBC LEED criteria a 100ft buffer from field delineated wetlands is being implemented on this site. (The buffer is the dark dashed line on the upland side of the wetlands indicated on the attached sketch). For the most part, the trail is located out of this buffer with the exception of the portion in the "peninsula" area in the NW. LEED allows the trail to be constructed of an impervious material if it stays out of the buffer, but must be constructed of mulch if located within the buffer. In either case, NCDENR says that this trail must be assumed as "built upon" impervious area and addressed with SWM measures. Further, if the trail area cannot be counted as impervious area managed by the wet ponds - even though portions of it will be graded to direct runoff by sheetflow directly into the ponds - this would then require separate and numerous individual treatment practices along the trail to satisfy all requirements. We are asking NCDENR to please consider that this trail is not located in an ultra -urban location where its additional impervious area would be a considerable detriment to a mostly impervious environment and require strict compliance with SWM policy and consider the pedestrian only use of this trail (no vehicles/pollutants), the very intense implementation of the proposed integrated SWM practices which are designed to treat all on -site impervious area, the conservation of natural area to the top of the slope at the 100ft buffer which would serve as a densely vegetated and forest littered buffer strip for filtering and velocity dissipation of runoff from the trail to the wetlands and reconsider the requirement for SWM treatment of this trail. We look forward to discussing this with you in further detail. Please feel free to contact this office when you have had a chance to review. Thank you, David K.

The project site is located at Marine Corps Base (MCB) Camp Lejeune in Onslow County, North Carolina. The proposed development is on approximately 25 acres and is bound by Birch Street to the south as shown in Figure I and Figure 2. The proposed project includes the development of a physical fitness center as shown in the attached plans, Appendix A. The proposed project has been design in accordance with LID implementation guidelines per current NAVFAC policy directive and USGBC LEED criteria. IL Existing Conditions The proposed project site is currently an undeveloped, wooded area with exception to an existing sidewalk, running parallel to Birch Street. A review of the topographic survey shows grades on the site ranging from approximately elevation 5 to elevation 20. The site generally has 0 to 6% slopes. According to Table 3-4 in the North Carolina Department of Environment and Natural Resources (NCDENR) Stormwater BMP Manual, the near surface soils in Onslow County are classified as Hydrologic Group B. A geotcchnical investigation was completed in June 2010. An infiltration site visit was completed by Vincent Lewis of NCDENR in July 2010. The results of the geotcchnical investigation and the infiltration site visit have been submitted with this package as Appendix B. IIL Wetlands and Waters of the United States A wetland delineation of the proposed project area was completed by the United States Army Corps of Engineers on October 22, 2007. The Notification of Jurisdictional Determination is attached as Appendix C. No permanent impacts to wetlands are proposed for this project. Temporary impacts to wetlands associated with the installation of underground utilities, will be avoided through directional drilling. There are no Waters of the Unites States on the proposed project site. In order to comply with USGBC LEER criteria, a 100ft buffer from field delineated wetlands to all impervious surfaces has been implemented in the site plan. IV. Proposed Development The proposed P 1160 Camp Lejeune Physical Fitness Center includes the development of one fitness center building, two parking lots, a recreation trail, a turf field, and associated access roads. The proposed project is on 25.03 acres. The post -development impervious area of the proposed development has been calculated to be approximately 7.54 acres or 30.10%. V. Stormwater Analysis Onslow County is a coastal county located within the White Oak River Basin. Thus, stormwater management measures have been designed in accordance with the Coastal Stormwater Rules Session Law 2008-21 I. The proposed project area drains to the Beaverdam Creek, Index Number: 19-20-I. According to North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Camp Lcieune P1160 Birch Street Physical Fitness Center August 2010 KHA Job # 148136002 http://maps.onslowcountync.gov/gomaps/map/map.cfm?CFID=128703&CFTOKEN=4581... 8/ 11 /2010 Quality the proposed project drains to SB waters. The build upon area is greater than 24%; therefore, the project is considered High -Density. Per the stormwater quality requirements, the first 1.5" of rain must be stored, controlled, and treated for 85% to 90% of the Total Suspended Solids (TSS). If wet ponds are used as a Best Management Practice (BMP) the temporary pool must drawdown between 48 and 120 hours. Per the stormwater quantity requirements, the storage volume must be discharged at a rate equal to or less than the pre -development discharge rate for the I -year 24-hour storm. Additionally, discharge directed to flow through wetlands must do so at a non -erosive velocity. The calculations and supplemental forms submitted with this narrative demonstrate that the proposed project'will meet all requirements of the Coastal Stormwater Rules Session Law 2008-211 The storm water management design proposes an integrated system of bioretcntion basins, pervious pavement, and two wet detention ponds to satisfy the LID implementation guidelines per current NAVFAC policy directive. However, because of specific soil and groundwater conditions encountered on the site the -.-bioretention.basins.and.pervious-pavement,.will.not.be.used-toward credit to satisfy the State stormwater requirements. Therefore, the two wet ponds shown are designed to filly satisfy all State stormwater requirements and the permit request will be based exclusively on the two wet detention ponds. VL Design Procedure The limits of the study area were established by determining the areas contributing runoff to the site using available topographic information. The topographic map and wetland delineation illustrate that the entire site drains west and north towards Beaverdam Creek, which outfalls into Wallace Creek Index Number: 19-20. Structural measures will be required for conveying and controlling increases in stormwater runoff directly related to the increase in impervious area due to the P 1160 Physical Fitness Center development. Increases in impervious area have been minimized through use of pervious pavement utilized in parking stalls and walkways. Additionally, clearing and grading are being held tight to the building and parking areas to preserve as much of the natural wooded area as practical. Runoff from rainfall events will be controlled by a series of drainage inlets and be conveyed using underground piping networks. Each of these networks will empty directly into one of two on -site wet detention ponds with forebay. The wet ponds located will outfall into unnamed ditches, which are tributaries to Beaverdam Creek, which outfalls into Wallace Creek Index Number: 19-20. The stormwater networks and basins will treat runoff' from the entire build upon area, with exception to a small portion of the jogging trail located north of the physical fitness center building. The conservation of natural area to the top of the slope at the I00ft buffer will serve as a densely vegetated and forest littered buffer strip for filtering and velocity dissipation of runoff from this portion of the trail to the wetlands. The existing and proposed drainage systems have been evaluated for peak now rates using ICPR software. ICPR utilizes SCS curve number methods of generating hydrographs. Rational Method (Q=CIA), Manning's Equation, and StormCAD software have been used in the design of the proposed stormwater system.

There is too much collection, BMPs, and concentration of BUA for it to be low density. Since the site will be considered high density, the trail will also have to be collected and treated. I understand that it will be nearly impossible given the location and nature of the trail to collect and treat the runoff. Unfortunately, I haven't been able to come up with many options to get around treating this runoff given the current design of the fitness center other than to use a raised open slatted decking as the walkway instead of the mulch. Raised, open slatted decking is not considered to be an impervious surface by DWQ.

Subject: RE: Camp Lejeune Physical Fitness Center: Scoping Meeting Hi Christine, Since we will be considering the mulch trail as part of our BUA, what stormwater requirements for this area will we need to meet? Due to the placement of the trail and our intent to minimize and avoid disturbance and clearing, collecting runoff from the trail does not seem likely. I have in my meeting notes that this area might be looked at as low density. If so, under the low density requirements we would not need to collect or treat the runoff from the trail. Can you confirm this and help explain anything I am missing? What type of supporting calculations/narrative would you be expecting for a trail such as this? Thank you, in advance, for any information you can provide. Talk to you soon Christine! Rachel A. Oberle, EIT Kimley-Horn and Associates, Inc. (p) 757-548-7324 From: Nelson, Christine [mailto:christine.nelson@ncdenr.gov] Sent: Wednesday, July 14, 2010 3:25 PM To: Oberle (Watts), Rachel Cc: Sauro, Tom; Towler CIV David W; Russell, Janet Subject: RE: Camp Lejeune Physical Fitness Center: Scoping Meeting Rachel, Thanks for the information and details. From the details of the grasspave2 system, it seems very similar to the plastic turf reinforcing grids shown in Figure 18-1 of the BMP manual. So the areas proposed as grasspave2 will be considered as BUA unless the design and site meets the pervious pavement criteria. As for the mulch trail - since the trail is being compacted to 95%, it too will need to be considered as BUA. When evaluating the site to see if you get credit for the permeable pavement, please ensure that all the design criteria area met. I noticed that one requirement is that the top 3-ft of soil must not have a texture finer than Loamy very fine sand. With the clay layer starting around 2 ft below grade, that may be difficult. I'm sure you've read through the chapter, but the other design specs are in Section 18.3.3 of the BMP manual. As for the bio-retention cells, we'll see what Vincent says about the SHWT, but I noticed Major design element #6 says that bioretention should not be used when the confining layer is less than 2 feet below the bottom of the BMP. With such a deep confining layer potentially starting at around 2 feet below grade, it may be hard to meet this requirement. I also noticed that your soil mixture doesn't specify a low P-index (#16 of the design elements). If the in -situ soil allows it, you may want to consider providing an IWS layer as shown on pages 12-8 and 12-9. You will also want to be careful with the capped cleanouts and set them high enough that the maintenance crew and equipment won't damage them. I think this answers all the questions raised during our meeting last week. Let me know if I missed one or if you clarification is needed.

The project site is located at Marine Corps Base (MCB) Camp Lejeune in Onslow County, North Carolina. The project site is on approximately 25 acres. The proposed development is bound by Birch Street to the south as shown in Figure I and Figure 2. The proposed project includes the development of a physical fitness center as shown in the attached plans, Appendix A. II. Existing Conditions The proposed project site is currently an undeveloped, wooded area. There is an existing sidewalk, running parallel to Birch Street through the project site. A review of the topographic survey shows grades on the site ranging from approximately elevation 5 to elevation 20. A geotechnical investigation was completed in June 2010. The results of the geotechnical investigation have been submitted with this package as Appendix B. III. Wetlands and Waters of the United States A wetland delineation of the proposed project area was completed by the United States Army Corps of Engineers on October 22, 2007. The Notification of Jurisdictional Determination is attached as Appendix C. No permanent impacts to wetlands are proposed for this project. Temporary impacts to wetlands associated with the installation of underground utilities, will be minimized and/or avoided through directional drilling. There are no Waters of the Unites States on the proposed project site. IV. Proposed Development The proposed project includes the development of one Department of Det'ense Physical Fitness Center. The P 1160 Camp Lejeune Physical Fitness Center includes the construction of one fitness center building, two associated parking lots, a recreation trail, and a turf field. The proposed project is on 25.03 acres. The post -development impervious area of the proposed development has been calculated to be approximately 4.99 acres or 19.95%. The following Best Management Practices will be included in the proposed development to act as stormwater controls: pervious pavements, four bioretention cells, and one wet detention pond with sediment forebay. V. Stormwater Analysis Onslow County is a coastal county located within the White Oak River Basin. Thus, stormwater management measures have been designed in accordance with the Coastal Stormwater Rules Session Law 2008-211. The proposed project area drains to the Beaverdam Creek, Index Number: 19-20-1. According to North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Quality the proposed project drains to SB waters. The build upon area is less than 24%, but stormwater structural controls are proposed; therefore, the project is considered High -Density. P1160 Camp Lejeune Physical Fitness Center June 2010 KHA Job # 148136002 Per the stormwater quality requirements, the first 1.5" of rain must be stored, controlled, and treated for 85% to 90% of the Total Suspended Solids (TSS). If wet ponds are used as a Best Management Practice (BMP) the temporary pool must drawdown between 48 and 120 hours. Per the stormwater quantity requirements, the storage volume must be discharged at a rate equal to or less than the pre -development discharge rate for the I -year 24-hour storm. Additionally, discharge directed to flow through wetlands must do so at a non -erosive velocity. The calculations and supplemental forms submitted with this narrative demonstrate that the proposed project will meet all requirements of the Coastal Stormwater Rules Session Law 2008-21 1. V I. Design Procedure The limits of the study area were established by determining the areas contributing runoff to the site using available topographic information. The topographic map and wetland delineation illustrate that the entire site drains west or northwest towards Beaverdam Creek. According to fable 3-4 in the North Carolina Department of Environment and Natural Resources (NCDENR) Stormwater BMP Manual, the near surface soils in Onslow County are classified as Hydrologic Group B. Structural measures will be required for conveying and controlling increases in stormwater runofidirectly related to the increase in impervious area due to the P 1160 Physical Fitness Center development. Increases in impervious area have been minimized through use of four types of pervious pavement, utilized in parking areas, drive isles, and walkways. Additionally, these pervious pavements provide storage and treatment for a certain portion of runoff from rainfall events. Runofl' that is not stored in the previous pavements will be directed to either a bioretention cell or the wet detention basin. Four bioretention cells are proposed along the perimeter of the fitness center building. Because storage potential is limited in these bioretention cells, each one will have an overflow weir that will direct flow to the forebay of the wet detention basin. The forebay of the wet detention basin will receive water from the following sources: drainage inlets in the parking areas and drive isles, bioretention overflow weirs, and sheet flow. The forebay is connected to the wet pond through two large diameter pipes in order that the two basins act as a single wet detention pond. The wet pond will outfall into an unnamed ditch on the southwest side of the subject property. The unnamed ditch is a tributary to Beaverdam Creek, which outfalls into Wallace Creek. The existing and proposed drainage systems have been evaluated for peak flow rates using [CPR software. ICPR utilizes SCS curve number methods of generating hydrographs. Rational Method (Q=CIA), Manning's Equation, and StormCAD software have been used in the design of the proposed stormwater system.

The construction at this site is planned to consist of building a 2-story Physical Fitness Center building of steel frame and load bearing CMU wall design supported on shallow foundations. At this time the conceptual site plans indicate that the building will have a footprint area of about 69,000 to 70,000 square feet. The construction at this site is also planned to consist of paved driveways and parking areas, underground utilities and other associated infrastructure components. Our field exploration program included five (5) 30-foot deep Standard Penetration Test (SPT) borings, drilled by G E T Solutions, Inc. within the footprint of the proposed structures. Additionally, four (4) 10-foot deep Standard Penetration Test (SPT) borings were drilled within the proposed pavement areas along with CBR testing. A brief description of the natural subsurface soil conditions is tabulated below: RANGES OF AVERAGE STRATUM DESCRIPTION SPT() N- DEPTH (Feet) VALUES Borings: B-1 through B-5,.and P-1 through P-4 0 to 1 to 4 inches of TOPSOIL 0.08 — 0.33 0.08 — 0.33 SAND SAND (SM) with varying amounts of silt and clay; 4 to 10 to I SILT (ML) encountered at Boring P-4 only SILT 2 5 2.0 CLAY (CL) with varying amounts of sand and silt. to O10 II The soils within this stratum extended to the boring 5 to 16 8 termination depth at Borings P-1 and P-2. This soil stratum was not encountered at Boring P-4. 8-10 SAND (SP-SM, SM) with varying amounts of silt to III and clay. The soils within this stratum extended to 5 to 39 10 to 30 the boring termination depth at Borings B-1, through B-5, P-3 and P-4 Note (1) SPT = Standard Penetration Test, N-Values in Blows -per -foot At the time of our field drilling activities, the groundwater level was recorded at the boring locations at depths ranging from 11.5 to 13 feet below existing site grade elevations. These groundwater levels correspond to elevations ranging from about 5.5 to 6 feet (MSL). The following evaluations and recommendations were developed based on our field exploration and laboratory -testing program: GET JUN 2 2 2010 '�Y: Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G • Field testing program during construction to include, subgrade proofrolling, compaction testing, and foundation excavation observations for bearing capacity verification. All other applicable testing, inspections, and evaluations should be performed as indicated in the North Carolina State Building Code (2006 International Building Code with North Carolina Amendments). An estimated cut depth of about 6 inches will be required to remove the topsoil and associated root mat from within the construction areas. • Some subgrade improvements should be anticipated within the construction areas (undercutting and backfilling with select fill) as a result of potentially soft/loose subgrade soils containing appreciable amounts of fines (silt and clay). • Expansion index testing completed on the shallow subsurface clays at the project site revealed a very low to low expansion portential. • Shallow foundations designed using a net allowable bearing capacity of 2,000 psf (24-inch embedment, 24-inch width). • Estimated post -construction total and differential settlements up to 1-inch and inch, respectively. • The foundations should also be designed with the use of top and bottom reinforcing steel for added rigidity and to increase the foundation performance with respect to settlement. • Concrete Masonry Unit wall construction should be designed to contain construction joints at on -center distances not exceeding 25 feet. These joints will provide for more flexible wall members that are less likely to crack as a result of settlement. • It is noted that, in accordance with the NC Building Code; Chapter 16, this site is classified as a site Class D, based on which seismic designs should be incorporated. This recommendation is based on the data obtained from the completed SPT borings as well as our experience with shear wave velocity testing performed on projects within the vicinity of the site. • Pavement sections to be designed using a CBR value of about 7.2, typical pavement sections are provided in the body of the report. This summary briefly discusses some of the major topics mentioned in the attached report. Accordingly, this report should be read in its entirety to thoroughly evaluate the contents. ii JUN 2 2 2010 GET Report of Subsurface Investigation and Geotechnical Engineering Services June 16, 2010 P-1160 Physical Fitness Center MCB, Camp LeJeune, North Carolina GET Project No: JX10-103G Where excessively unstable subgrade soils are observed during proofrolling and/or fill placement, it is expected that these weak areas can be stabilized by means of thickening the base course layer by 2 to 4 inches and/or lining the subgrade with geotextile fabric (Mirafi HP270 or equivalent). These alternates are to be addressed by the Geotechnical Engineer during construction, if necessary, who will recommend the most economical approach at the time. 4.11 Soil Permeability At the time of our subsurface exploration procedures, the proposed storm water management pond area had not been determined. Therefore, this testing was not performed. Soil permeability testing can be performed once the stormwater pond areas have been determined. The results of this testing can be provided as an addendum to this report. 5.0 CONSTRUCTION CONSIDERATIONS /J 5.1 Drainage and Groundwater Concerns _/a�Q �/ It is expected that dewatering may be required for excavations that extend near or below the existing groundwater table. Dewatering above the groundwater level could probably be accomplished by pumping from sumps. Dewatering at depths below the groundwater level may require well pointing. It would be advantageous to construct all fills early in the construction. If this is not accomplished, disturbance of the existing site drainage could result in collection of surface water in some areas, thus rendering these areas wet and very loose. Temporary drainage ditches should be employed by the contractor to accentuate drainage during construction. If water collects in foundation excavations —it will-t a necessary-to-remove_water_from the excavations, remove saturated soils, and re -test the adequacy of the bearing surface soils to support the design bearing pressure prior to concrete placement. , 5.2 Site Utility Installation The base of the utility trenches should be observed by a qualified inspector prior to the pipe and structure placements to verify the suitability of the bearing soils. If unstable bearing soils are encountered during installation some form of stabilization may be required to provide suitable bedding. This stabilization is typically accomplished by providing additional bedding materials (NCDOT No. 57 stone). In addition, depending on the depth of the utility trench excavation, some means of dewatering may be required to facilitate the utility installation and associated backfilling. All utility excavations should be backfilled with structural fill, as described in Section 4.3 of this report. - _ f� 13 JUN 2 2 2010 GEC' Russell, Janet From: Rachel.Oberle@kimley-horn.com Sent: Tuesday, June 22, 2010 8:44 AM To: Russell, Janet Cc: david.towler@usmc.mil; Tom.Sauro@kimley-horn.com; RDeReuil@suffolkconstruction.com Subject: Request for Express Stormwater Permit Review: Camp Lejeune P 1160 Physical Fitness Center Attachments: Express Request_Stormwater Permit -Camp Lejeune P1160 Physical Fitness Center.pdf Hi Janet, Please find attached the Request for Express Stormwaler Permit Review for Camp Lejeune P1160 Physical Fitness Center.

At the end are some diagrams of the solar panels that apply to this decision. Are they the same kind that you are proposing? You will likely need to at least do a plan revision to that permit to demonstrate the change in material. (plan revisions are free in the regular program and $500 in Express) The two projects I permitted with these, actually required modifications because of slight increases in the parking area to allow for the large supports.
