A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. It appears that the SA/DA ratio has not been updated to consider the new percent of impervious area found within the drainage area. Please modify the calculations and other supporting documents to reflect the correct SA/DA ratio. 2. The layer for the proposed contours/BMPs appears to be turned off on plan sheet CS-107. Please submit a plan sheet with this layer turned onto indicate the location of forebay #2. Please provide two sets plans with each sheet signed, sealed, and dated. The permit cannot be approved with only the title page of the plan set signed, sealed, and dated. 4. Due to the minor nature of these comments, the express Add Info fee has been waived for this request for additional information. 5. Please keep in mind that changing one number may change other numbers and require the calculations, supplements, and other supporting documentation to be updated. Verify all numbers are correct to ensure consistency in the application documents. Please note that this request for additional information is in response to a preliminary review. The requested information should be received in this Office prior to January 27, 2010, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee.

Please note that a second significant request for additional information may result in the return of the project. If the project is returned, you will need to reschedule the project through the Express coordinator for the next available review date, and resubmit all of the required items, including the application fee. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.

This letter will address each comment through additional information, figures and attachments. The responses below are numbered to correspond with the comments contained in the December 21, 2010 letter (see attached). 1. Please see the attached Typical Duplex Unit Planting Plans, which provides a key between duplex number (I through 6) and housing style (A through F). 2. Please see the attached plans, which have been modified to illustrate access to the pool. The impervious calculation has been updated to reflect this change. 3. Please see the attached plans and the supporting impervious calculations. Additional information has been provided for clarity. Please note that an allowance has been provided for future impervious area due to expansion of the Community Center and/or the parking area. 4. Please see attached stormwater plans. The offsite drainage area has been labeled on the stormwater drainage area plan sheet. 5. Please see attached stormwater plan sheet CG-500. 6. Please see attached grading plans. Additional grading information for the driveways to Lincoln Park School has been included and is illustrated on the plan sheets and is accounted for in the impervious area calculations. 7. The label for "Residential 5" has been removed from plan sheet CG-101. 8. For your information, gutters will be used on all of the houses to collect stormwater runoff. To ensure that all runoff from the rear of lots 18, 170, 161 and 156 is collected and conveyed to the BMP, we've revised the grading behind these units to ensure the runoff will sheet flow to a drainage Swale that is directed to the stormwater system. 9. Please see attached grading plans. Additional spot elevations and proposed contours ha been added to further demonstrate drainage patterns in common areas. ��J j�j� JAN 1 .1 ZO10 BY:____ 10.

Sullins Director Baker, Deputy Public Works Officer Subject: Request for Additional Information Stormwater Project No. SW8 090816 Lincoln Park Residential Development Onslow County Dear Mr. Baker: Dee Freeman Secretary The Wilmington Regional Office received an Express Stormwater Management Permit Application for Lincoln Park Residential Development on December 15, 2009. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. In the calculations, the proposed amount of impervious area for the housing is broken down by the house style. Please provide a key or some means of relating the house style to the housing information on the plans, which uses labels A to F. For instance, which house style relates to the duplex labeled with an A and D as located on lot 11? 2. Please demonstrate on the plans how the pool will be accessed by visitors. No sidewalks or other means of access have been indicated on the plans. 3. Plan sheet CS-107 indicates that the Community Center is 51,000 sf. Please clarify if this is the area dedicated to the community center or the amount of impervious used by to the community center. 4. Please identify the offsite drainage area(s) on the plans, preferably on the drainage area map. 5. Provide the information on the stormwater collection system, including pipe inverts, in the plans. 6. Please provide more grading details for the driveways to Lincoln Park School (state stormwater permit no. SW8 090918). If runoff from these areas will be directed to the stormwater collection. system for the Lincoln Park residential development, this additional area and impervious area will need to be considered within the offsite drainage area and offsite impervious area for this project. 7. The label for "Residential 5" is blocking some of the details on plan sheet CG-101. Please ensure labels are not blocking information on the plans. 8. Will gutters be used on the houses to collect runoff and direct it to the stormwater collection system? For instance the runoff from the back of the houses on lot 18 and half of lot 170 at the intersection of Road F and Road D do not appear to be collected. Other lots in question include: half of lot 161, lot 156, and 156. If so, show the roof drain collection lines on the plans. If the proposed or existing grade will be utilized to sheet flow the runoff to the collection system, please ensure enough detail is provided to demonstrate the drainage pattern. 9. Please provide proposed contours or additional spot elevations in the common areas, such as on plan sheets CG-104 to CG-106, to help demonstrate the drainage patterns.

The construction within the Phase I portion of the site is planned to consist of building 103 duplex structures, one (1) community center (approximately 10,000 square feet in plan area), associated paved roadways, storm water management (BMP) ponds, and other pertinent infrastructure components. Our field exploration program included thirty-three (33) 20- to 25-foot deep SPT borings, six (6) 15-foot deep SPT borings, as well as twelve (12) 10-foot deep hand auger borings drilled by G E T Solutions, Inc. within the footprints of the proposed structure, pavement areas, and storm water management pond (BMP) areas. A brief description of the natural subsurface soil conditions is tabulated below: AVERAGE RANGES OF DEPTH (Feet) STRATUM DESCRIPTION SPTI'I N- VALUES 0.0 to Topsoil 2 to 24 inches of Topsoil 0.2 — 2.0 0.2 — 2.0 to SAND (SP, SP-SM, SM, SC-SM, SC) with varying 10, 15, 20, or 25 amounts of silt and/or clay 2 to 36 0.25 CLAY (CL, CL-ML, CH) and/or SILT (ML); Borings to II B-6, B-7, B10, B-28, B-33, B-35 through B-37, B- 3 to 17 9 0 43, B-46, B-49, B-50, B-52, B-54, B-55, CBR-3, CBR-17 through CBR-20, and BMP-6 only. 9.0 — 10.0 to III SAND (SP-SM, SM) with trace amounts of 13.0 organics; Borings B-33 and B-35 only 2 to 3 8.0 — 11.5 PEAT (PT) with varying amounts of silt and/or clay to IV and/or Organic Fat CLAY (OH); Borings B-28, 2 to 4 9.5 — 15.0 B-32, B-35, and CBR-19 only Note (1) SPT = Standard Penetration Test, N-Values in Blows -per -foot The groundwater level was recorded at the boring locations and as observed through the wetness of the recovered soil samples during the drilling operations. The initial groundwater table was measured to occur at depths ranging from 7 to 16 feet below varying existing site grades at the boring locations, which corresponded to an elevation ranging from 6 to 16 feet MSL. Groundwater monitoring wells were installed at the location of borings BMP-4 through BMP-6 and BMP-8 and 48-hour groundwater readings were noted to indicate a static water level of 8 to 15 feet below exi rades, which corresponds to an elevation ranging from 7 to 9.5 feet MSL. RECF`1 DEC 1 5 2009 Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp LeJeune, North Carolina GET Project No: EC09-227G The following preliminary evaluations and recommendations were developed based on our field exploration and laboratory -testing program: • 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) and/or UFC (Unified Facilities Criteria). - - - - - — • An estimated cut depth of approximately 8 to 12 inches with isolated areas up to about 24 inches will be required to remove the topsoil and associated root mat. • The subgrade evaluation procedures should include a series of test pit excavations to further evaluate these soils and to substantiate their suitability to remain in -place. Some subgrade improvements should be anticipated within the construction areas (undercutting and backfilling with select fill) as a result of potentially unsuitable/unstable cohesive subgrade soils. • Building 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 for the buildings up to 1-inch and 1/2-inch, respectively. • The PEAT (PT) soils encountered at the location of boring B-32 are not considered to be suitable for shallow foundation support. Furthermore, these soils are anticipated to result in adverse long term settlements. Preliminary alternative foundation design recommendations for the structures within the vicinity of this boring are provided in Section 4.5.2. Additional borings should be performed within the vicinity of boring B-32 (Lot 27) in order to delineate the extent of the PEAT (PT) soils and more accurately determine alternative foundation design criteria. • Based on our experience with similar construction in the general area of the project site, the site is within a site class 'D' in accordance with Table 1615.1.1 of the 2006 International Building Code. 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. Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G 1.0 PROJECT INFORMATION 1.1 Project Authorization G E T Solutions, Inc. has completed our subsurface investigation and geotechnical engineering services for the proposed Family Housing project located along the south side of Brewster Boulevard within the MCB Camp Lejeune military installation in North Carolina. The Geotechnical Engineering Services were conducted in general accordance with G E T Solutions, Inc. revised Proposal No. PEC09-116G, dated February 5,-2009 and submitted on the date of February 6, 2009. Furthermore, these services were provided in conjunction with our previously completed feasibility study reported on the date of October 14, 2008 (GET Project No. EC08-321G). Authorization to proceed with the Geotechnical Engineering Services was received from Mr. Tom Sauro of Kimley-Horn and Associates, on the date of July 28, 2009 in the form of an email. 1.2 Project Description The construction within the Phase I portion of the site is planned to consist of building 103 duplex structures, one (1) community center (approximately 10,000 square feet in plan area), associated paved roadways, storm water management (BMP) ponds, and other pertinent infrastructure components. The proposed residential structures are anticipated to consist of single to two-story buildings constructed of wood frame design and supported by shallow foundations. The proposed loading conditions associated with the residential structures were not known at this time. However, the maximum wall loads are not anticipated to exceed about 3 klf. The first floors are anticipated to consist of either a slab - on -grade design or post -tensioned slab design with their distributed loads not expected to exceed 150 pounds per square foot. The proposed community center structure is anticipated to be of a single story building constructed of a combination of load bearing concrete masonry unit (CMU) walls, structural steel, and/or light gauge metal stud frame design. The proposed loading conditions associated with the structure were not known at this time. However, based on our experience with similar projects the maximum column and wall loads are not anticipated to exceed about 30 kips and 3 klf. The first floor is anticipated to be of slab -on -grade design with their distributed loads not expected to exceed 150 pounds per square foot. The structures' first floor elevations are expected to be located slightly above the existing site grades, which were generally noted to range from about 16 to 25 feet MSL. Accordingly, fill operations are expected to be minimal (up to 2 feet) in order to establish the design grade elevations. 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 aAropriate.

Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune. North Carolina GET Project No: EC09-227G 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. Any statements in this report or on the boring logs regarding odors, color, unusual or suspicious items or conditions are strictly for the information of the client. 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 design parameters within the proposed building areas, a total of thirty three (33) 20- to 25-foot deep Standard Penetration Test (SPT) borings (designated as B-23 through B-55) were drilled by G E T Solutions, Inc. within the limits of the proposed structures. Additionally, a total of ten (10) 25-foot deep SPT borings (designated as B-3 through B-12) were completed during our original feasibility study of the Family Housing project site and provided in our report dated October 14, 2008 (GET Project No. EC08-321G). In order to explore the general subsurface soil types and to aid in developing associated pavement design parameters within the proposed pavement areas, twelve (12) 10-foot deep hand auger borings (designated as CBR-10 through CBR-21) were drilled within the proposed roadway areas. Additionally, a total of three (3)10-foot deep borings (designated as CBR-1, CBR-3, CBR-4) were completed within the proposed pavement areas during our previously referenced feasibility study of the Family Housing project site. Dynamic Cone Penetrometer (DCP) testing and bulk soil sampling was performed at each of the pavement boring locations. The bulk subgrade soil samples were collected from depths ranging from 0.5 to 3.0 feet below existing grades. The bulk soil samples were returned to our laboratory and subjected to CBR testing in accordance with ASTM standards. Finally, in order to explore the general subsurface soil types and to aid in developing associated storm water design parameters, six (6) 15-foot deep SPT borings (designated as BMP-3 through BMP-8) were performed within the proposed storm water management pond areas. Additionally, a groundwater monitoring well was installed at each of the boring locations identified as BMP-4 through BMP-6 and BMP-8. The number of borings to be drilled for this project was specified by the developer and Kimley-Horn and Associates, Inc., and their locations were established and identified in the field by G E T Solutions, Inc. Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G The recently completed borings were performed in conjunction with and labeled consecutively with the previously completed borings for the project's feasibility study as well as the subsurface exploration procedures recently completed for the proposed Camp LeJeUne Elementary School project reported on the date of September 11, 2009 (GET Project No. EC09-228G). Accordingly, the borings performed during our initial feasibility study for the proposed housing project (B-3 through B-12, CBR-1, CBR-3, and CBR-4) are included herein. Whereas, the remaining borings identified as B-1, B-2, B-13 through B-22, CBR-2, CBR-5 through CBR-9, BMP-1, and BMP-2 are not provided as they were not performed within the limits of the proposed housing project. Standard Penetration Tests were performed in the field in general accordance with ASTM D 1586. The tests were performed continuously from the existing ground surface to depths 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. 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. 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. Following the exploration procedures, the borings were backfilled with a neat cement grout mix in accordance with NCDENR requirements, excluding the locations where groundwater monitoring wells were installed.

Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G The number of borings to be drilled for this project was specified by the developer and Kimley-Horn and Associates, Inc. Furthermore, the recently completed boring locations were previously established by G E T Solutions, Inc. during the proposal process in conjunction with the reduced scope of services stipulated by the developer at an approximate frequency of 1 boring for every fourth or fifth duplex structure. These previously established boring locations were identified in the field by G E T Solutions Inc. personnel with the use of a Global Positions System unit as well as the "State Plane" coordinates selected from the project site plan and converted to latitude and longitude coordinates. The approximate boring locations are shown on the "Boring Location Plan" — attached to this report (Appendix I, Figure 1). This plan was developed based on the site plan provided to G E T Solutions, Inc. 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. Twenty eight (28) representative soil samples were selected and subjected to laboratory testing, which included natural moisture, 4200 sieve wash, Atterberg Limits, and/or organic content testing and analysis, in order to corroborate the visual classification.

The site currently consists of an undeveloped wooded parcel with an existing dirt roadway bisecting the site and an open agricultural area located within the east portion of the site. Existing grade elevations throughout the proposed project site generally ranged from about 16 to 25 feel MSL, as indicated on the topographic site plan provided by Kimley-Horn and Associates, Inc. Furthermore, the site was visually estimated to be relatively level with less than 1 to 2 feet of change in elevation in 50!linear feet. RECEIV' DEC 1 5 2009 i i Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11. 2009 Family Housing MCB Camp Lejeune I Camp Lejeune, North Carolina GET Project No: EC09-227G The project site is bordered to the east by a wooded area followed by an existing recreational area associated with an existing school, to the north by Brewster Boulevard followed by a wooded parcel, and to the west and south by a wooded parcel. 3.2 Site Geology The project site lies within a major physiographic province called the Atlantic Coastal Plain. Numerous transgressions and regressions of the Atlantic Ocean have deposited marine, lagoonal, and fluvial (stream lain) sediments. The regional geology is very complex, and — generally consists of interbedded layers of varying mixtures of sands, silts and clays. Based on our review of existing geologic and soil boring data, the geologic stratigraphy encountered in our subsurface explorations generally consisted of marine deposited sands, silts and clays. 3.3 Subsurface Soil Conditions The results of our recently and previously completed soil test borings at this site indicated the presence of approximately 2 to 24 inches of topsoil material at the boring locations. Underlying the surficial organic materials (Topsoil) and extending to the boring termination depths of 10, 15, 20, and 25 feet below existing site grades, the natural subsurface soils were generally uniform throughout the site. These soils were noted to be primarily granular in nature and were classified as SAND (SP, SP-SM, SM, SC-SM, SC) with varying amounts of silt and clay. The Standard Penetration Test (SPT) results, N-values, recorded within these granular soils ranged from 2 to 36 blows -per -foot (BPF), indicating a very loose to dense relative density. The granular soils encountered at the location of borings B-33 and B-35, at a depth ranging from and 9 to 13 feet below existing grades were noted to contain trace amounts of organics. These organic granular soil deposits were noted to range in thickness from about 3 to 4 feet. Additionally, more significant deposits of organic soils were encountered at the location of borings B-28, B-32, B-35, and CBR-19 at varying depths ranging from 8 to 9.5 feet and 10 to 15 feet below existing grades. These organic soil deposits were noted to range in consistency from PEAT (PT) with varying amounts of silt, clay, and/or sand to Organic Fat CLAY (OH) with varying amounts of Peat, and ranged in thickness from 0.5 to 4 feet. Finally, deposits of CLAY (CL, CL-ML, CH) and/or SILT (ML) were encountered within the subsurface granular soils between varying depths ranging from 0.25 to 9 feet below the existing site grade elevations at the location of borings B-6, B-7, B-10, B-28, B-33, B-35 through B-37, B-43, B-46, B-49, B-50, B-52, B-54, B-55, CBR-3, CBR-17 through CBR-20, and BMP-6. DEC 1 5 2009 Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G The subsurface description is of a generalized nature provided to highlight the major soil strata encountered. The records of the subsurface exploration are included in Appendix II (Boring Log sheets) and in the Generalized Soil Profile presented in 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. 3.3 Groundwater Information The groundwater level was recorded at the location of borings B-3 through B-12, B-23 through B-55, CBR-3, CBR-15, and BMP-3 through BMP-8 as observed through the wetness of the recovered soil samples during the drilling operations. The initial groundwater table was measured to occur at depths ranging from 7 to 16 feet below current grades at the boring locations. Based on the site topography information provided by Kimley-Horn and Associates, Inc., the encountered groundwater level corresponds to an elevation generally ranging from 6 to 16 feet MSL. However, the groundwater levels encountered at the location of borings B-33 and B-41 (14 feet MSL and 16 feet MSL, respectively) may be perched water as a result of restrictive Clayey SAND (SC) layers. The groundwater level was not encountered at the location of borings CBR-1, CBR-4, CBR-10 through CBR-14 and CBR-16 through CBR-21 as the boring termination depth occurred at about 10 feet below the existing site grade elevations. The varying ground water depths and elevations appear to have been contributed by variations of the existing site grade elevations in combination with the natural site drainage features. The boreholes at the location of borings B-3 through B-12, B-23 through B-55, CBR-1, CBR-3, CBR-4, CBR-10 through CBR-21, BMP-3, and BMP-7 were backfilled upon completion for safety considerations. As such, the reported groundwater levels may not be indicative of the static groundwater level. However, groundwater monitoring wells were installed at the location of borings BMP-4 through BMP-6 and BMP-8. The static groundwater levels encountered following a period of 48-hours after the monitoring wells were installed were noted to occur at depths ranging from 8 to 15 feet below the existing site grade elevations. These groundwater depths were correlated to elevations ranging from about 7 to 9.5 feet MSL at the location of borings BMP-5, BMP-6, and BMP-8. Existing site grade elevations were not available within the vicinity of boring BMP-4. More specific information regarding the 48-hour groundwater readings and estimated seasonal high groundwater depths and elevations for each boring location within the proposed storm water management (BMP) pond areas are provided in the following table (Table III — Groundwater Summary). Additionally, Table III on the following page includes the average estimated seasonal high ground water elevations for each BMP pond location. 10 1 5 2009 lJ ZQ2 DEC 1 5 2009 BY.- Final Report of Subsurface Investigation and Geotechnical Engineering Services Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G Table III — Groundwater Summary September 11, 2009 48-hour Estimated Average Estimated Boring Initial 48-hour Groundwater Seasonal High Seasonal High No. Groundwater Groundwater Elevation Groundwater Groundwater Level (ft)' Level (ft)* (ft MSL) " Elevation Elevation (ft M S L ft MSL '" BMP-3 _ 12.0.__.

As previously noted, the seasonal high ground water elevation information noted above is considered to be estimated and is based on the results of our visual soil classification program. Additionally, the static ground water levels encountered at the monitoring well locations as well as the seasonal high ground water levels are likely affected by variations in seasonal precipitation magnitudes, in -situ soil conditions throughout the BMP pond areas, in conjunction with the existing and finished elevations. Perched groundwater levels are anticipated to occur throughout the site as a result of potential restrictive SAND (SC, SC-SM), SILT (ML) and/or CLAY (CL, CL-ML, CH) encountered throughout the site at depths ranging from 0.2 feet to 9 feet below existing grades. 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. Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G 4.0 EVALUATION 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. The subsurface soils generally encountered throughout a majority of the project site are -suitable for the use of shallow foundation designs. However, subsurface organic laden granular soils (SAND, SP-SM, SM) and/or more significant deposits of organic soils (Fat Organic CLAY; OH and/or PEAT; PT) were encountered at the location of borings B-28, 13- 32, B-33, B-35, and CBR-19 at depths ranging from 8 to 15 feet below existing grades. The granular soils noted to contain trace amounts of organics and the relatively thin deposits of more significant organics are not anticipated to contribute significant foundation settlement magnitudes associated with the proposed structures. However, excessive shallow foundation settlements are anticipated to occur for the structures within the vicinity of boring B-32 associated with the PEAT (PT) soils encountered at a depth of 10 to 14.5 feet below existing grades. Additional subsurface explorations within the vicinity of boring B-32 is considered to be advisable in order to delineate the limits of the PEAT (PT) soils and identify those structures requiring alternative foundation systems. Preliminary alternative foundation design recommendations are presented in Section 4.5.2 of this report. 4.1 Clearing and Grading The proposed construction area should be cleared by means of removing the existing topsoil and associated root mat. It is estimated that a cut averaging about 8 inches in depth, with isolated areas exceeding 12 inches (such as B-4, B-9, B-41, CBR-15, CBR-19, and BMP-8), will be required to remove the topsoil and its associated root mat and expose the underlying CLAY (CL, CL-ML), SILT (ML), and/or SAND (SP, SP-SM, SM, SC-SM, SC). This cut is expected to extend deeper in isolated areas to remove deeper deposits of unsuitable material 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. t =BY: GET Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G Following the initial clearing, the resulting exposed subgradewill generally be comprised of CLAY (CL, CL-ML), SILT (ML), and/or SAND (SM, SC-SM, SC) containing an appreciable amount of fines. 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/soft 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, SM, SW, GP, GW), 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. 13 !ZffcE1v_K75 SET DEC 1 5 2009 BY: Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11. 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G Other soils types such as SAND (SC-SM, SC) and/or CLAY (CL) may be used as fill provided that they are properly placed and compacted as noted herein. These soil types are typically moisture sensitive and unstable conditions and/or the inability of the materials to be properly compacted may occur. Accordingly, should these soils be selected for use as fill it is considered necessary to allow them to be dried to a moisture content suitable for placement and compaction. 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 Suitability of On -site Soils The subsurface CLAY (OH, CL, CL-ML, and CH), SILT (ML), PEAT (PT), and/or SAND (SC and SC-SM) soils encountered at the boring locations do not appear to meet the criteria recommended in this report for reuse as structural fill, but may be used as fill within green areas. However, the SAND (SM, SP-SM, and SP) soils may be suitable 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 substantiate the suitability of excavated soils for reuse as fill within construction areas. 4.5 Foundation Discussion As previously indicated in Sections 3.3 and 4.0 of this report, the subsurface soils generally encountered throughout a majority of the project site are suitable for the use of shallow foundation designs. However, the subsurface soils encountered at the location of borings B-28, B-32, B-33, B-35, and CBR-19 were noted to contain organic deposits. Furthermore, these organic soil deposits were noted to range in consistency from SAND (SP-SM, SM) with trace organics, to more significant organic soils consisting of Organic Fat CLAY (OH) and/or PEAT (PT). 14 PIECE' Jvk T; GET DEC 1 5 2009 BY:� Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G Although the granular soils (SAND: SP-SM, SM) noted to contain trace amounts of organics as well as the relatively thin more substantial organic soil layers are not anticipated to contribute significant amounts of shallow foundation settlement, the PEAT (PT) deposit is anticipated to present more detrimental settlement magnitudes. The above mentioned organic laden granular soils and relatively thin deposits of more significant organics were generally encountered at the location of borings B-33, B-35, and CBR-19. The PEAT (PT) soils anticipated to result in adverse shallow foundation settlements were encountered at the location of boring B-32 (Lot 27). Considering the proposed construction scheme consisting of 1 to 2 story wood frame structures supported by shallow foundations, the organic laden soils are anticipated to be located generally below the foundation zone of influence. Accordingly, the granular soils noted to contain trace amounts of organics and the relatively thin deposits of more significant organics are anticipated to result in tolerable shallow foundation settlements (up to 1-inch). However, the PEAT (PT) soils are anticipated to result in global long term settlements estimated to exceed about 2 to 3 inches. Accordingly, as an alternative to the proposed shallow foundation designs, reinforced mat foundations, post tensioned reinforced slabs, and/or deep foundations can be used to minimize and/or prevent these settlement magnitudes. The use of mat foundations and/or post tensioned reinforced slabs will not eliminate the potential for these settlement magnitudes to occur, however they would be more uniform in nature and minimize differential settlements. The use of deep foundations with pile supported first floor slabs (structural slabs) would eliminate the potential for these adverse foundation settlements. However, global settlements of the adjacent site grade elevations are anticipated to occur differentially from the structure. Additional borings will need to be performed within the vicinity of boring B-32 (Lot 27) in order to delineate the extent of the PEAT (PT) soils. 4.5.1 Shallow Foundation Design Recommendations Provided that the recommended earthwork construction procedures are properly performed, the proposed structures (excluding those within the vicinity of boring B-32, Lot 27) can be supported by shallow spread footings, bearing over firm natural soil or well compacted structural fill material. The footings can be designed using a net allowable soil pressure of up to 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, 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. 1' ' CJI;FE.,ZD GET DEC 1 5 Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G 4.5.2 Preliminary Alternative Foundation Design Recommendations As indicated in Section 4.5 of this report, the subsurface organic soils encountered at the location of borings B-28, B-32, B-33, B-35, and CBR-19 are anticipated to result in adverse long term global settlement magnitudes exceeding that indicated in Section 4.5.1 of this report for shallow foundation design/construction. Accordingly, it may be advantageous to support the proposed structures within the vicinity of these borings by means of reinforced mat foundations, post tensioned reinforced slabs, and/or deep foundations. The use of mat foundations and/or post tensioned reinforced slabs will not eliminate the potential for these settlement magnitudes to occur, however they would be more uniform in nature and minimize differential settlements. The use of deep foundations with pile supported first floor slabs (structural slabs) would eliminate the potential for these adverse foundation settlements. However, global settlements of the adjacent site grade elevations are anticipated to occur differentially from the structure. In the event that deep foundations are selected it is recommended that both the structure and its first floor slabs be supported by the pile foundation system. Additionally, it is anticipated that a deep foundation design may consist of driven round timber piles and/or helical anchors installed to a depth of at least 25 to 30 feet below existing site grade elevations. In order to provide deep foundation design recommendations and to more accurately delineate the limits of the subsurface organic soils it would be necessary to perform additional Standard Penetration Test (SPT) borings within the vicinity of the above mentioned boring locations. 4.6 Shallow Foundation Settlements As previously indicated, the subsurface soils encountered within the vicinity of boring B-32 (Lot 27) were noted to contain a deposit of PEAT (PT). Furthermore, these soils will result in excessive long term foundation settlements without the use of a pile supported structure and first floor slab. Accordingly, it is considered advisable to complete additional subsurface explorations (SPT borings) within the vicinity of boring B-32 in order to more accurately delineate the limits of these unsuitable soils. Preliminary alternative foundation design recommendations are presented in Section 4.5.2 of this report. It is estimated that, with proper site preparation, the maximum resulting total settlement of the foundations associated with the remaining structures should be up to 1 inch. The maximum differential settlement magnitude is expected to be less than %-inch between adjacent footings (wall footings and column footings of widely varying loading conditions). The settlements were estimated on the basis of the results of the field penetration tests. Careful field control will contribute substantially towards minimizing the settlements. 16 DEC 1 5 2009 Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G 4.7 Shallow 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 perform 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", an open graded washed stone (such as No. 57 stone or equivalent), 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. This construction procedure will provide for a net allowable bearing capacity of 2,000 psf. A 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 re - compacted. 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. 4.8 Floor Slabs The floor slabs may be constructed as slab -on -grade members provided the previously recommended earthwork activities and evaluations are carried out property. 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 (SP) 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.

Alternatively, monolithic slab - on -grades with turn down foundations may be used. However, as previously indicated, slab -on -grade construction (monolithic and/or floating slabs) is anticipated to experience excessive settlements for the structures within the vicinity of borings B-28, B-32, B-33, B- 35, and CBR-19. Alternative recommendations for the first floor construction are provided in Section 4.5.2 of this report. 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 Pavement Design The California Bearing Ratio (CBR) test results indicated soaked CBR values ranging from 11.1 to 25.7, averaging 18.6. The in -situ field Dynamic Cone Penetrometer (DCP) test results indicated an in -place correlated CBR value ranging from about 5 to 9. The relatively low correlated CBR values obtained from the field DCP testing procedures is contributed to the very loose condition (not compacted) of the shallow subsurface soils. These associated CBR values will be greatly improved provided that the earthwork recommendations, including the subgrade preparation and fill placement/compaction procedures are successfully completed as recommended in Sections 4.2 and 4.3 of this report. A comprehensive summary of the CBR test data and the moisture density relationship curves (Proctors) are presented in Appendix IV. Additionally, the results of the field DCP testing procedures are presented in Appendix V. The average CBR value obtained from the laboratory CBR testing procedures 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 12.4 was used in designing the pavement sections. Furthermore, the Average Daily Traffic (ADT) loading criteria provided by Kimley-Horn and Associates, Inc. and the information listed on the following page were also used to complete the pavement design analysis, which was performed in accordance with AASHTO requirements.

Zt s Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G 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. 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 500x or equivalent). These alternatives are to be addressed by the Geotechnical Engineer during construction, if necessary, who will recommend the most economical approach at the time. 4.10 Seismic Evaluation It is noted that, in accordance with the INC 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 25-foot deep SPT borings as well as our experience with shear wave velocity testing performed on projects within the vicinity of this site. In order to substantiate the site classification provided above a 100-foot deep CPT boring and soil shear wave velocity testing with liquefaction potential analysis should be performed. G E T Solutions, Inc. would be pleased to provide these services should they be determined necessary. 4.11 Storm Water Design Parameters Six (6) infiltration tests were performed at the location of borings BMP-3 through BMP-8. The tests were performed at depths ranging from about 7 to 11 feet below current grades, respectively. The boreholes were prepared utilizing an auger to remove soil clippings from the base. Infiltration testing was then conducted within the vadose zone utilizing a Precision Permeameter and the following testing procedures. 20 DEC 1 5 2009 Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G A support stand was assembled and placed adjacent to each borehole. This stand holds a calibrated reservoir (200 ml or 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 4-meter (approximately 13-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_Ievel_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 tests), the hydraulic conductivity of the shallow soils is tabulated in the following table (Table V) and is presented on the "Hydraulic Conductivity Worksheet" reports (Appendix VII), included with this report.

Camp Lejeune, North Carolina GET Project No: EC09-227G 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. If water collects in foundation excavations, it will be necessary to remove the water form the excavation, remove the saturated soils, and re -test the adequacy of the bearing surface soils to support the design bearing pressure prior to concrete placement. Perched water table conditions within the select fill materials and/or shallow subsurface soils may be encountered throughout the project site during periods of heavy precipitation and/or during the "wet' season. This is expected to occur as a result of the surficial and/or shallow subsurface restrictive soil layers generally encountered throughout the project site at depths ranging from 0.3 feet to 9 feet. Accordingly, some undercut and backfill with suitable structural fill materials and/or de - watering of the structural fill materials and/or shallow subsurface soils may be required during the subgrade preparation and/or foundation construction procedures. Alternatively, an under drain system may be used in order to aid in alleviating the potential for saturated bearing soil conditions and/or to aid in minimizing foundation undercutting procedures. 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. 22 11"R�C�K-Tv�FmD GET DEC 1 5 2009 Final Report of Subsurface Investigation and Geotechnical Engineering Services September 11, 2009 Family Housing MCB Camp Lejeune Camp Lejeune, North Carolina _ GET Project No: EC09-227G The subsurface CLAY (OH, CL, CL-ML, and CH), SILT (ML), PEAT (PT), and/or SAND (SC and SC-SM) soils encountered at the boring locations do not appear to meet the criteria recommended in this report for reuse as structural fill, but may be used as fill within green areas. However, the SAND (SM, SP-SM, and SP) soils may be suitable 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 substantiate the suitability of excavated soils for reuse as fill within construction areas. - 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.

October 28, 2009 RE: Final Report of Subsurface Investigation and Geotechnical Engineering Services Family Housing — MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G Addendum No.1 Dear Mr. Sauro: The following is an addendum to our original "Final Report of Subsurface Investigation and Geotechnical Engineering Services" (EC09-227G; dated September 11, 2009) as it applies specifically to the newly proposed storm water management pond Nos. 3 and 4 for the above referenced project. More specifically, following the completion of our subsurface exploration procedures and Geotechnical Engineering analysis, it was requested to perform additional explorations and Geotechnical Engineering services associated with the above mentioned newly proposed storm water management ponds. Field Exploration and Testing: In order to explore the general subsurface soil types and to aid in developing associated storm water design parameters, two (2) 12-foot deep hand auger borings (designated as BMP-9 and BMP-10) were performed within the proposed storm water management pond areas. The exploration depths were limited to that noted above due to cave-in occurring as a result of the encountered ground water levels and associated granular soil conditions. More specific information regarding boring locations and depths is provided in the following table (Table I — Boring Schedule). Table I — Boring Schedule Boring Boring GPS Coordinates Boring Depth Surface Boring Location Description Number (feet) Elevation Latitude Longitude ft MSL)` BMP-9 15 21.5 BMP Pond No. 4; Approximate Center 34' 42.600' 77' 22,151' BMP-10 15 19.0 BMP Pond No. 3, Approximate Center 340 42.489' 770 22.109' Additionally, saturated hydraulic conductivity (infiltration) testing was performed at each boring location in order to provide additional storm water design parameters. 50 1 F;as't Elizabeth Slice( • Elizabeih City.

The approximate boring locations are shown on the "Boring Location Plan" attached to this report (Appendix I, Figure 1). This plan was developed based on the site plan provided to G E T Solutions, Inc. by Kimley-Horn and Associates, Inc. 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 bya Geotechnical Engineer in accordance with ASTM D2488. A total of two (2) representative soil samples were selected and subjected to laboratory testing, which included natural moisture and -#200 sieve wash testing and analysis, in order to corroborate the visual classification. These test results are provided in the following table (Table II - Laboratory Test Results) and are presented on the "Boring Log" sheets, included with this report.

Underlying the surficial organic materials (Topsoil) and extending to the boring termination depths of 12 feet below existing site grades, the natural subsurface soils were generally uniform throughout the site. These soils were noted to be primarily granular in nature and were classified as SAND (SP, SP-SM, SM, SC-SM, SC) with varying amounts of silt and/or clay CEIVED DEC 1 5 2009 G Final Report of Subsurface Investigation and Geotechnical Engineering Services October28,2009 Family Housing — MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G Amendment No. 1 The subsurface description is of a generalized nature provided to highlight the major soil strata encountered. The records of the subsurface exploration are included in Boring Log sheets and in the Generalized Soil Profile, 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. Groundwater Information: The groundwater level was recorded at the location of borings BMP-9 and BMP-10 as observed through the wetness of the recovered soil samples during the drilling operations. The initial groundwater table was measured to occur at depths ranging from 10 to 11 feet below current grades at the boring locations. Based on the site topography information provided by Kimley-Horn and Associates, Inc., the encountered groundwater level corresponds to an elevation generally ranging from 9 to 10.5 feet MSL. The boreholes at the location of borings BMP-9 and BMP-10 were backfilled upon completion for safety considerations. As such, the reported groundwater levels may not be indicative of the static groundwater level. The "Soil Survey of Onslow County, North Carolina" provided by the U.S. Department of Agriculture indicates that soils located within this project site consist predominantly of the Onslow loamy fine sand, Baymeade fine sand, Rains fine sandy loam, and Kureb fine sand. More specifically, it was determined that the proposed storm water retention pond No. 3 (boring BMP-10) and No. 4 (boring BMP-9) are located within the areas identified in the "Soil Survey of Onslow County, North Carolina" to contain the Baymeade and Onslow series soils, respectively. These associations indicate moderately well drained to well drained soils with moderately high to high water transmittal capabilities. The soils recovered at the project site appear to be consistent with the information provided on the "Soil Survey of Onslow County, North Carolina". Table III on the following page of this report provides more detailed information regarding the soil series indicated in the "Soil Survey of Onslow County, North Carolina" within the vicinity of the completed borings BMP- 9 and BMP-10 as well as the associated soil characteristics. 1 5 2009 Final Report of Subsurface Investigation and Geotechnical Engineering Services October 28, 2009 Family Housing - MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G Amendment No. 1 Table III - Storm Water Pond Soils: U.S. Department of Agriculture Soil Survey Storm Water Drainage Water Pond No. Boring No. Soil Series** Class** Transmittal Capacity** 3 BMP-10 Baymeade fine Well Drained High Sand 4 3MP-9 Onslow Loamy Moderately Moderately fine Sand I Well Drained I Hi h to Hi h - The information provided above is based on our review of the "Soil Survey of Onslow County, North Carolina" provided by the U.S. Department of Agriculture. As previously noted, the soil sample colors were identified using the Munsell°Soil Color Charts to aid in identifying the estimated SHWT. It is noted that soil morphology is not a reliable indicator of the SHWT in drained soils, as indicated in the "Soil Morphology as an Indicator of Seasonal High Water Tables" (prepared by Peter C. Fletcher; U.S. Department of Agriculture Soil Conservation Service). Accordingly, the SHWT depths at the location of borings 3MP-9 and BMP-10 were estimated based on a combination of the Munsell° color classifications and our experience with similar soil and site conditions. The current groundwater levels encountered at the project site and the estimated SHWT depths are anticipated to be contributed to a combination of the varying existing site grade elevations as well as the existing drainage features. Table IV below includes the encountered ground water elevations and the individual estimated seasonal high ground water elevations for each BMP boring.

Final Report of Subsurface Investigation and Geotechnical Engineering Services October 28, 2009 Family Housing — MCB Camp Lejeune Camp Lejeune, North Carolina GET Project No: EC09-227G Amendment No. 1 Storm Water Desiqn Parameters: One (1) infiltration test was performed at each of the boring locations (BMP-9 and BMP-10). The tests were performed at depths ranging from about 9 to 10 feet below current grades, respectively. The boreholes were prepared utilizing an auger to remove soil clippings from the base. Infiltration testing was then conducted within the vadose zone utilizing a Precision Permeameter and the following testing procedures. A support stand was assembled and placed adjacent to each borehole. This stand holds a calibrated reservoir (200 ml or 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 4-meter (approximately 13-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 (Q), 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 tests), the hydraulic conductivity of the shallow soils is tabulated in the following table (Table V) and is presented on the "Hydraulic Conductivity Worksheet° reports (Appendix VII), included with this report.

Peak Flow Ca1CuJatlOnS Spine of the slate's stoI III 'ester programs require prop iding attenuation of p,�ak runoff; for example, that the post -development flow rate fat the one-\ ear, 2-1-hour storm min; not exceed tltc ptc-cevelopment floe rate (Neese an(I'fat-Pamlico NSIV Programs). In addition, it is also important to compute flow testes front the watershed tcheo designing BIMPs such as grassed swales, filter strips, and restored riparian buffers_ The primary method that is used to determine peak runoff rate for North Cajohna's stolillwater programs is the Rational Method. The Rational equation is given as: Q=C*I*A Where: Q = Estimated design discharge (cfs) C = Composite runoff coefficient (unitless) for the �%atershed I = Rainfall intensity (in/hr) for the designated design slot u in the geographic region of interest A = Watershed area (ac) The composite runoff coefficient reflects the surface characteristics of the contributing watershed. The range of runoff coefficient values varies from 0 - 1.0, with higher values corresponding to greater runoff rate potential. The runoff coefficient is determined by estimating the area of different land uses within each drainage area. Table 3-2 presents values of runoff coefficients forvarious pervious and impervious u s surfaces. The Division believes that the Rational Method is most applicable to drainage areas approximately 20 acres or less.

PRELIMINARY STORMWATER NARRATIVE LINCOLN PARK RESIDENTIAL DEVELOPMENT CAMP LEJEUNE ONSLOW COUNTY, NORTH CAROLINA PREPARED FOR: North Carolina Department of Environment and Natural Resources PREPARED BY: KIMLEY-HORN AND ASSOCIATES, INC. 501 INDEPENDENCE BOULEVARD SUITE 300 CHESAPEAKE, NC 23320 SEPTEMBER 2009 KHA # 116319001 �E C E I V ED �ppp�,Vuu{ SEP 1 12009 DWQ PROJ # OVERVIEW 1. Back round This report contains the approach and preliminary results of a stormwater impact analysis conducted for the proposed Lincoln Park Residential Development. The project site is located at Marine Corps Base (MCB) Camp Lejeune in Onslow County, North Carolina. The project site is on approximately 140 acres bounded by Brewster Boulevard to the North, east of Paradise Point Golf Course, and west of Stone Street as shown in Appendix A: Vicinity Map. The proposed project includes the development of an elementary school as shown in Appendix B: Residential Site Plan. LA ncoln Park School development is being proposed adjacent to the school development. The Lincoln School Development includes the development one Department of Defense Education ActivityEA) School. A separate permit application will be submitted for the school development. The layoute both the proposed school and residential development are shown in Appendix C: Phase I Site Plan.proposed school and residential developments are Phase 1 of six proposed phases of development at Camp Lejeune. The proposed master development is shown in Appendix D: Master Development. An Environmental Assessment (EA) of the master development was completed by the United States Marine Corps in accordance with the National Environmental Policy Act (NEPA). Pursuant to this report, A Finding Of No Significant Impact (FONSI) was issued in August 2008. 11. Existing Conditions The proposed project site is currently an undeveloped, wooded area. There is a narrow dirt road running from the northeast corner of the project site in the southwest direction. A review of the topographic survey shows grades on the site ranging from elevation 14 to elevation 30. A preliminary geotechnical investigation was completed in August 2008. An executive summary of the results is attached in Appendix E: Preliminary Geotechnical Investigation. III. Wetlands and Waters of the United States A wetland delineation of the proposed project area was confirmed by the United States Army Corps of Engineers on March 2009. The Notification of Jurisdictional Determination is attached in Appendix F. Less than 0.1 of an acre of wetlands will be impacted due to underground utilities associated with the proposed development. There are no Waters of the Unites States on the proposed project site. IV. Pr000sed Development The proposed project includes the development of 340 family housing units for enlisted military personnel, one community center, and connecting right-of-ways. The layout of the proposed project is shown in Appendix B: Residential Site Plan. Five interconnected wet detention basins will serve the residential development site to treat stormwater runoff. The proposed project is on approximately 140 acres, of which approximately 130 acres will be disturbed. The post -development impervious area of the proposed development was calculated to be approximately 32% or 45 acres. E C E I V ED SEP 1 1 2009 DWQ PROJ # V. Stormwater Analvsis Onslow County is a coastal county located within the White Oak River Basin. Thus, stormwatcr management measures shall be designed in accordance with the Coastal Stormwater Rules Session Law 2008-211. The proposed project area drains to the Morgan Bay, Index Number: 19-18. According to North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Quality the proposed project drains to SC waters. The build upon area is greater than 24%; therefore, the proposed project is considered High -Density. Per the stormwater quality requirements, the first 1.5" of rain must be stored, controlled, and treated for 85% 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 l-year 24-hour storm. Additionally, discharge directed to flow through wetlands must do so at a non - erosive velocity. VI. Desien Procedure The limits of the study area were established by determining the areas contributing runoff to the site using available topographic information. The topographic information further revealed three main stormwater egress points, each of which has a significant drainage area composed of lands that are both a part of and separate from the proposed project site. According to Table 34 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 runoff directly related to the increase in impervious area due to the Lincoln Park Residential Development. These measures will be designed to meet both the quantity and quality requirements for the State of North Carolina as described in Section V. 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 the on -site wet ponds. Five interconnected wet ponds have been designed to control and treat stormwater runoff from the residential development. The locations of the proposed ponds are illustrated on Appendix B: Residential Site Plan. The five interconnected wet ponds controlling and treating runoff from the residential development will have a single outfall into an unnamed ditch on the south west corner of the subject property. This unnamed ditch flows to an existing culvert under Eden Street and outfalls into Morgan Bay, an arm of the New River. The stormwater networks and wet ponds will treat runoff from the entire project area with exception to two areas. The first area is approximately 3 grassed acres on the north boundary, which will sheet flow to existing culverts on Brewster Boulevard. The second area includes the back yards of the homes on the eastern project boundary, which will sheet flow to an undeveloped wooded area to the east. �E C E 6 V ED �U;SO SEP 1 12009 DWO PROJ R The proposed ponds will have a combined footprint area of approximately 6.5 acres (normal water surface area). They are expected to have a minimum of 3:1 side slopes with a 10' wide aquatic bench with 10:1 side slopes. The proposed pond will have a forebay sized at 20% of the volume of the permanent pool. The bottom elevations are expected to be 5.0' below the normal water surface elevation for all the proposed ponds. The volume between the pond bottom and the normal pool is considered the water quality or permanent pool volume. The volume above the normal pool elevation is for water quantity (stormwater management). Based on the existing wetland areas and groundwater information, we expect the normal water surface elevations can be maintained by the groundwater. The existing and proposed drainage systems will be 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 will also be used in the design of the proposed stormwater system. A Manning's n value of 0.013 will be used for the storm sewer pipe. VII. Erosion Control Erosion and Sedimentation control measures shall be designed in accordance with 15A NCAC, Chapter 4 (NC Sedimentation Pollution Control Act of 1973). The project site will be surrounded by silt fence and all existing and proposed stormwater structures will be fitted with inlet protection devices to prevent sediment from exiting the project site. Tree protection will be utilized in all tree -save areas. The proposed ponds are anticipated to act as temporary sediment basins during construction. p�E C E B 11 ED SEP 1 12009 �:� a f - Golf E .AIMEWSTiil P a rq 10-1, 5 SOU EVAR sarwSTE Golf Course Off WHITE: ----")0 A K lank z . . . . . . . . . . 47 . . . . . ........

The geotechnical engineering services were conducted in general accordance with the scope presented in G E T Proposal No. PVB08-463G, dated August 12, 2008. Authorization to proceed with the services was obtained from Mr. Joseph V. Modica, P.E. of Kimley-Horn and Associates, Inc. 1.2 Project Description The construction within the Phase I portion of the site is planned to consist of building 190 duplex structures, one (1) 500-student elementary school (approximately 100,000 square feet in plan area), one (1) community center (approximately 10,000 square feet in plan area), associated paved roadways and other infrastructure components. The proposed residential structures are anticipated to consist of single to two-story buildings constructed of wood frame design and supported by shallow foundations. The proposed loading conditions associated with the residential structures were not known at this time. However, the maximum wall loads are not anticipated to exceed about 3 klf. The first floors are anticipated to consist of either a slab -on -grade design or post tension slab design with their distributed loads not expected to exceed 150 pounds per square foot. The proposed school and community center structures are anticipated to consist of single story buildings constructed of a combination of load bearing concrete masonry unit (CMU) walls, structural steel, and/or light gauge metal stud frame design. The proposed loading conditions associated with these structures were not known at this time. However, the maximum column and wall loads are not anticipated to exceed about 100 kips and 6 klf. The first floor is anticipated to consist of slab -on -grade design with their distributed loads not expected to exceed 150 pounds per square foot. The structures' first floor elevations are expected to be located slightly above the existing site grades, thus fills are expected to be minimal (up to 2 feet). Additionally, associated paved roadways and other pertinent infrastructure will be implemented at this property. 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.

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: General assessment of the soils revealed by the borings performed at the proposed development. 2. General location and description of potentially deleterious material encountered in the borings that may interfere with construction progress or structure performance, including existing fills or surficial/subsurface organics. 3. 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. Evaluation of the on -site soils for re -use as structural fill. 6. Feasibility of utilizing a shallow foundation system for support of the proposed structures. Preliminary design parameters required for the foundation system, including foundation sizes, allowable bearing pressures, foundation levels, and expected total and differential settlements. Pavement design based on the field exploration activities (4 CBR tests with 10-foot deep hand auger borings), our experience with similar soil conditions, as well as the anticipated Average Daily Traffic (ADT) loads provided by Kimley-Horn and Associates, Inc. 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. Nil Solutions, Inc.It Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G 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 design parameters, twelve (12) 25-foot deep Standard Penetration Test (SPT) borings (designated as B-1 through B-12) and four (4) 10-foot deep hand auger borings (designated as CBR-1 through CBR-4) were drilled within the proposed construction areas. Specifically, borings B-1 and B-2 were performed within the proposed school footprint and borings B-3 through B-12 and CBR-1 through CBR-4 were performed within the proposed residential construction area. The SPT borings were performed utilizing mud -rotary drilling techniques with a truck - mounted drill rig. Standard Penetration Tests (SPT) were performed in the field in general accordance with ASTM D 1586. The tests were performed continuously from the existing ground surface to a depth of 10 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. 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. 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. Following the completion of each boring, the bore holes were backfilled with grout as required by NCDENR regulations. Additionally, a total of four (4) bulk soil samples were collected from the approximate pavement subgrade elevation in the vicinity of borings CBR-1 through CBR-4. The bulk subgrade samples were collected from beneath the existing surficial organic soils at depths ranging from 0.5 to 2 feet below existing grades. The bulk soil samples were returned to our laboratory and subjected to CBR testing in accordance with ASTM standards. The boring locations were located and staked in the field by a representative of G E T Solutions, Inc. The approximate boring locations are shown on the attached 'Boring Location Plan", (Appendix 1). 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 staff Geotechnical Engineer -In -Training in accordance with ASTM D2488. A total of eight (8) representative split spoon soil samples were selected and subjected to natural moisture and 4200 sieve wash testing and analysis in order to corroborate the visual classification of the granular soils. These test results are tabulated on the following page and are also presented on the 'Boring Log" sheets (Appendix 11). Solu[bns, Inc.

A summary of the CBR test data and the moisture density relationship curves (Proctors) are presented in Appendix IV. 3.0 SITE AND SUBSURFACE CONDITIONS 3.1 Site Location and Description The project site is located along the south side of Brewster Boulevard just west of the intersection with Stone Street in the Camp LeJeune military installation in North Carolina. Specifically, the project site is bordered to the east by a wooded area followed by an existing recreational area associated with an existing school, to the north by Brewster Boulevard followed by a wooded parcel, and to the west and south by a wooded parcel. The proposed project site currently consists of a wooded parcel with an existing dirt roadway bisecting the site and an open agricultural area located within the east portion of the site. 3.2 Site Geology The project site lies within a major physiographic province called the Atlantic Coastal Plain. Numerous transgressions and regressions of the Atlantic Ocean have deposited marine, lagoonal, and fluvial (stream lain) sediments. The regional geology is very complex, and generally consists of interbedded layers of varying mixtures of sands, silts, clays and marine shell deposits. Based on our review of existing geologic and soil boring data, the geologic stratigraphy encountered in our subsurface explorations which generally consisted of marine deposited sands, silt and clays of the Belgrade Formation. Solutions, Inc. Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321G 3.3 Subsurface Soil Conditions The results of our soil test borings indicated the presence of topsoil material at each boring location ranging in thickness from 2 to 24 inches. Underlying the surficial organic materials (Topsoil) and extending to the boring termination depths of 10 and 25 feet below existing site grades, the natural subsurface soils were generally uniform throughout the site. These soils were noted to be primarily granular in nature and classified to consist of SAND (SP, SP-SM, SM, SC-SM, SC) with varying amounts of silt and clay. The Standard Penetration Test (SPT) results, N-values, recorded within these granular soils ranged from 2 to 36 blows -per -foot (BPF), indicating a very loose to dense relative density. Deposits of CLAY (CL, CH) were encountered within the subsurface granular soils between varying depths ranging from 0.25 to 6 feet and 18 to 25 feet below the existing site grade elevations at the location of borings B-1, B-2, B-6, B-7, B-10, and CBR-3. The subsurface description is of a generalized nature provided to highlight the major soil strata encountered. The records of the subsurface exploration are included in Appendix II (Boring Log sheets) and in the Generalized Soil Profile presented in 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. 3.4 Groundwater Information The groundwater level was recorded at the boring locations and as observed through the relative wetness of the recovered soil samples during the drilling operations. The initial groundwater table, where encountered, was determined to occur at depths ranging from 7 to 11.5 feet below current grades at the boring locations identified as B-1 through B-12 at the time of our site reconnaissance. The groundwater level was not encountered at the hand auger boring locations identified as CBR-1 through CBR-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. Perched groundwater levels are anticipated to occur throughout the site as a result of potential restrictive soil layers noted to consist of SAND (SC, SC-SM) and/or CLAY (CL, CH) encountered at a majority of the boring locations at depths ranging from 0.2 feet to 6 feet. WN Solutions, Inc. Report of Preliminary Subsurface Investigation 8 Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G 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, side walks, etc.). In the project's area, seasonal groundwater fluctuations of± 2 feet are common; 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, if necessary. 4.0 EVALUATION 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 areas should be cleared by means of removing all trees, surface vegetation, root mat, and topsoil or any otherwise unsuitable materials. It is estimated that a cut of about 6 to 8 inches in depth, with isolated areas of about 24 inches (such as B-4 and B-9) will be required to remove the topsoil materials. This cut is expected to extend deeper in isolated areas to remove deeper deposits of 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. The soils noted directly below the surficial organic materials (Topsoil) within the vicinity of borings CBR-2, CBR-3, B-4, B-7, B-9, and B-10 were noted to contain appreciable amounts of fines (SAND; SC, SC-SM and/or CLAY; CL, CH). The current (natural) moisture contents of the surface soils at the explored locations were estimated to be near or above their optimum moisture. 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 very soft soils may be required. The extent of the undercut will be determined in the field during construction, based on the outcome of the field testing procedures (subgrade proofroll). 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. Solutions, Inc. Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G Due to the potential for perched water and the presence of moisture sensitive soils near the surface, control of surface water is very important to the successful completion of the proposed construction. The contractor should plan his grading activities to control surface water and minimize erosion of exposed cut or fill material. This may include constructing temporary berms, ditches, flumes and/or slope drains to intercept runoff and discharge it in a controlled fashion, while complying with state and local regulations. 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 or his representative 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 or his representative. Subsequently and prior to the placement of any select fill materials, compaction tests should be performed on the existing subgrade soils within the proposed building and/or pavement footprints in order to verify that they have been compacted to at least 95% of the Modified Proctor (ASTM D1557). It is possible that some subgrade improvements will be required to provide suitable soils for foundation, slab, and/or pavement support. Preliminarily, unstable pavement and/or slab -on -grade subgrade soils are anticipated to be corrected by means of undercutting the subgrade soils, where necessary, to a depth of about 12 to 18 inches and backfill the resulting excavations with suitable select fill materials. Similarly, in the event that unstable foundation bearing soils are encountered it is anticipated that an undercut depth of about 1 to 2 feet and subsequent backfill with suitable select fill materials will result in suitable bearing conditions. Recommendations concerning the subgrade improvements (as necessary) should be more accurately determined in the field following the testing procedures as conditions are anticipated to vary. The project's budget should include an allowance for subgrade improvements (undercut and backfill with structural fill). 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 25% by weight of fines (SP, SM, SW, GP, GW), 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. Solutions, Inc. Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321G Other soils types such as SAND (SC-SM, SC) and/or CLAY (CL) may be used as fill provided that they are properly placed and compacted as noted herein. These soil types are typically moisture sensitive and unstable conditions and/or the inability of the materials to be properly compacted may occur. Accordingly, should these soils be selected for use as fill it is considered necessary to allow them to be dried to a moisture content suitable for placement and compaction. 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 should be placed in 4 to 8 inch loose lifts when compacted with the use of hand operated equipment and should be compacted to at least 95 percent of ASTM D1557. 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 Suitability of On -site Soils The subsurface CLAY (CL and CH) and/or SAND (SC and SC-SM) soils encountered at the boring locations do not appear to meet the criteria recommended in this report for reuse as structural fill, but may be used as fill within green areas. However, the SAND (SM, SP-SM, and SP) soils may be suitable 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 substantiate the suitability of excavated soils for reuse as fill within construction areas. 4.5 Preliminary Foundation Design Recommendations Provided that the construction procedures are properly performed, the proposed structures can be supported by shallow spread footings bearing upon firm natural soil, 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. Solutions, Inc.- Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G In order to develop the recommended bearing capacity of 2,000 pounds per square foot (psf), the base of the footings should have an embedment of at least 18 inches beneath finished grades and wall footings should have a minimum width of 20 inches for the proposed residential structures and 24 inches for the proposed elementary school and community center. 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 18-inch footing embedment is considered sufficient to provide adequate cover against frost penetration to the bearing soils. Alternatively, post -tensioned slab construction may be utilized to support the proposed residential structures. The post -tension slab foundations should be sized by the structural engineer. A subgrade modulus of 125 psi/in for compacted structural fill can be used in the design of the post -tensioned slab foundations. 4.6 Settlements It is estimated that, with proper site preparation, the maximum resulting total settlement of the proposed building foundations should be up to 1 inch. 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). The settlements were estimated on the basis of the results of the field penetration tests. Careful field control will contribute substantially towards minimizing the settlements. 4.7 Foundation Excavations In preparation for shallow foundation support, the footing excavations should extend into firm natural soil or well compacted structural fill. The foundation bearing capacities should be verified in the field during construction by means of performing an inspection of all footings. At that time, the Geotechnical Engineer or his representative will explore the extent of excessively loose, soft, or otherwise unsuitable material within the exposed excavations. Also, at the time of the footing observations, the Geotechnical Engineer or his representative should determine and perform the necessary testing and evaluations to further evaluate the foundation bearing soils. 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" 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. Solutions, Inc. Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G Immediately prior to reinforcing steel placement, it is suggested that the bearing surfaces of all footing and floor slab areas 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 foundation may be waived by the Geotechnical Engineer, where firm bearing soils are observed during the foundation 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. 4.8 Slab -on -Grade. Design The floor slabs may be constructed as slab -on -grade members provided the previously recommended earthwork activities and evaluations are carried out properly. It is recommended that all ground floor slabs be directly supported by at least a 4-inch layer of relatively clean, compacted, poorly graded sand (SP) 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 noted that all ground floor slabs may consist of "floating" slabs that are ground supported and not rigidly connected to walls or foundations. Alternatively, monolithic slab - on -grades with turn down foundations may be used. The slab -on -grade subgrade should be established by means of placing the recommended structural fill and compacting to at least 95% of the Modified Proctor maximum dry density (ASTM D 1557). This construction procedure will provide a subgrade modulus of at least 125 psi/in. 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. 10 Solutlons, Inc.:. Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G 4.9 Pavement Design The California Bearing Ratio (CBR) test results indicated soaked CBR values ranging from 14.1 to 17.9, averaging 15.7. 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 10.5 was used in designing the pavement sections. Furthermore, the Average Daily Traffic (ADT) loading criteria provided by Kimley-Horn and Associates, Inc. and the information listed below were also used to complete the pavement design analysis, which was performed in accordance with AASHTO requirements. Should any of the information below be incorrect G E T Solutions, Inc. should be notified to perform a subsequent analysis prior to paving operations.

Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321G The results of the pavement design analysis are included in Appendix V (Pavement Design Analysis). All pavement material and construction procedures should conform to Unified Facilities Criteria (UFC) and 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. 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 500x or equivalent). These alternatives are to be addressed by the Geotechnical Engineer during construction, if necessary, who will recommend the most economical approach at the time. 4.10 Seismic Evaluation It is noted that, in accordance with the INC 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 25-foot deep SPT borings as well as our experience with SPT borings and CPT soundings with shear wave velocity testing performed within the vicinity of this project site. In order to substantiate the site classification provided above a 100-foot deep CPT boring and soil shear wave velocity testing with liquefaction potential analysis should be performed. G E T Solutions, Inc. would be pleased to provide these services should they be determined necessary. 4.11 Soil Permeability At this time saturated hydraulic conductivity testing was not included in our scope of services. However, in order to assist with the storm water design, estimated permeability values of the subsurface soil conditions encountered at the completed boring locations are provided in Table III. Should a more accurate groundwater level be required, G E T Solutions, Inc. can install a series of ground water monitoring wells when we re -visit the project site to perform field saturated hydraulic conductivity testing. 12 Solutions, Inc. Report of Preliminary Subsurface Investigation 8 Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G Table III - Estimated Permeability Values Soil Classification Percent Silt and/or Clay Estimated Permeability Rate SP, SP-SM 0% to 15% 1.0E-03 cm/sec SM, SM-SC 15% to 30% 1.0E-05 cm/sec SC 30% to 50% 1.0E-06 cm/sec CL 50% to 70% with Liquid Limit less than 50 1.0E-07 cm/sec CL, CH 70% to 100% 1.0E-07 cm/sec 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. If water collects in foundation excavations, it will be necessary to remove the water form the excavation, remove the saturated soils, and re -test the adequacy of the bearing surface soils to support the design bearing pressure prior to concrete placement. Perched water table conditions within the select fill materials and/or shallow subsurface soils may be encountered throughout the project site during periods of heavy precipitation and/or during the "wet' season. This is expected to occur as a result of the surficial restrictive soil layers (CLAY: CL, SAND: SC, SC-SM) that were encountered at the location of borings B-1 through B-4, B-6, B-7, B-9, B-10, B-12, and CBR-1 through CBR-4 at depths ranging from 0.2 feet to 6 feet. Accordingly, some undercut and backfill with suitable structural fill materials and/or de -watering of the structural fill materials and/or shallow subsurface soils may be required during the subgrade preparation and/or foundation construction procedures. Alternatively, an under drain system may be used in order to aid in alleviating the potential for saturated bearing soil conditions and/or to aid in minimizing foundation undercutting procedures. 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. Again, we recommend that the contractor determine the actual groundwater levels at the time of construction to determine groundwater impact on this project. 13 Solutions, Inc. Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321G 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 a suitable bedding. This stabilization is typically accomplished by providing additional bedding materials (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. 5.3 Additional Geotechnical Investigation A comprehensive geotechnical investigation is recommended once the final layout (structure footprints and design grades), structural characteristics, and the structural loads are determined. The subsurface data documented during this feasibility study can be incorporated within the final geotechnical investigation. Specifically, it is recommended to perform additional SPT borings and/or DMT Soundings within the limits of the proposed commercial building areas along with a comprehensive laboratory testing program. Furthermore, it is recommended to perform CBR tests within the pavement areas to provide pavement design parameters. The frequency of tests should be developed based on the final design scheme. 5.4 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.

I've tried to gather answers to the questions that were brought up in the meeting. The BMP website is: htto://h2o.enr.state.nc.us/su/bmp forms htm This website has the application (SWU-101), application instruction sheet, supplement forms, and 0&M agreements. Please also ensure you are looking at the latest BMP chapters and using the most recent forms. Some of your questions (how deep can ponds be and SHWT in relation to ponds) can be answered by the updated BMP chapter as well as in the policy and technical guidance documents that were posted prior to the chapter being updated: http://h2o.enr.state.nc.us/su/state sw notices htm (this link is also available at the top of the BMP website) 2. Deep wet detention pond SW guidance: http://h2o.enr.state.nc.us/su/documents/Deepponds Original pdf Basically ponds can be a maximum of 20 ft deep, however it unclear if this 20 ft includes the sediment storage depth or not. If you think the final pond design will be deeper than 20 ft (including sediment storage), I will have to look into this a bit further. For Erosion & Sediment Control, Rhonda doesn't have an issue with a deep pond. She was thinking of another requirement when she mentioned the 15 ft. 3. Ponds and SHWT elevation guidance: http://h2o.enr.state.nc.us/su/documents/PondSHWT Original 1df This guidance discusses the criteria that must be evaluated in order for the permanent pool to be set more than 6" below the water table. Section 10.3.2 of the wet detention pond chapter in the BMP manual also mimics the guidance document. 4. Section 10.3.3 of the wet detention pond chapter in the BMP manual briefly goes into using multiple forebays. However, this section mostly covers how to size these multiple forebays such as providing a drainage area map for each forebay and calculations of the design volume in each forebay and the percent of the overall design volume in each forebay will be needed. With wet detention pond systems that propose to use multiple forebays separate from the main pond there are often 2 scenarios: a. the water level in the forebays are at the same elevation as the main pond b. the water level in the forebays are higher than in the main pond In scenario a, the forebays can be considered part of the main pond. Also remember to include the forebays in the average depth calcs. In scenario b, the forebay is excluded from the main pond. This means that the provided surface area, average depth, the temporary storage volume, and other pond design criteria must only be considered and contained in the main pond. In both of these scenarios, the supplement will need to be modified or another page should be added to describe the forebays in a similar manner as on the supplement. Also keep in mind that the pipes connecting these forebays to the main pond should be set above the sediment storage to prevent these from getting clogged up over time. When you are ready to schedule a submittal meeting, please contact Janet. It's best to contact her approx 2 weeks before the desired submittal date. Let me know if you have additional questions!

I talkith Linda regarding our question on the permanent pool being set above the SHWT. It's ok if the permanent pool elevation (PPE) is above the SHWT elevation. It's just that the PPE shouldn't be set significantly above the SHWT. For example, the SHWT shouldn't be below the bottom of the pond. Some of the concerns are: How will water stay in pond? Why not consider infiltration at this point? Hopefully this makes sense. Let me know if you have additional questions.

The geotechnical engineering services were conducted in general accordance with the scope presented in G E T Proposal No. PVB08-463G, dated August 12, 2008. Authorization to proceed with the services was obtained from Mr. Joseph V. Modica, P.E. of Kimley-Horn and Associates, Inc. 1.2 Project Description The construction within the Phase I portion of the site is planned to consist of building 190 duplex structures, one (1) 500-student elementary school (approximately 100,000 square feet in plan area), one (1) community center (approximately 10,000 square feet in plan area), associated paved roadways and other infrastructure components. The proposed residential structures are anticipated to consist of single to two-story buildings constructed of wood frame design and supported by shallow foundations. The proposed loading conditions associated with the residential structures were not known at this time. However, the maximum wall loads are not anticipated to exceed about 3 klf. The first floors are anticipated to consist of either a slab -on -grade design or post tension slab design with their distributed loads not expected to exceed 150 pounds per square foot. The proposed school and community center structures are anticipated to consist of single story buildings constructed of a combination of load bearing concrete masonry unit (CMU) walls, structural steel, and/or light gauge metal stud frame design. The proposed loading conditions associated with these structures were not known at this time. However, the maximum column and wall loads are not anticipated to exceed about 100 kips and 6 klf. The first floor is anticipated to consist of slab -on -grade design with their distributed loads not expected to exceed 150 pounds per square foot. The structures' first floor elevations are expected to be located slightly above the existing site grades, thus fills are expected to be minimal (up to 2 feet). Additionally, associated paved roadways and other pertinent infrastructure will be implemented at this property. 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. ® E C E U V E� AUG 2 12009 DWQ PROJ if --- Solutions, Inc. iw Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G 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: General assessment of the soils revealed by the borings performed at the proposed development. 2. General location and description of potentially deleterious material encountered in the borings that may interfere with construction progress or structure performance, including existing fills or surficial/subsurface organics. 3. 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. Evaluation of the on -site soils for re -use as structural fill. 6. Feasibility of utilizing a shallow foundation system for support of the proposed structures. Preliminary design parameters required for the foundation system, including foundation sizes, allowable bearing pressures, foundation levels, and expected total and differential settlements. 7. Pavement design based on the field exploration activities (4 CBR tests with 10-foot deep hand auger borings), ourexperience with similar soil conditions, as well as the anticipated Average Daily Traffic (ADT) loads provided by Kimley-Horn and Associates, Inc. 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. .Solutions, Inc*1P Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G 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 design parameters, twelve (12) 25-foot deep Standard Penetration Test (SPT) borings (designated as B-1 through B-12) and four (4) 10-foot deep hand auger borings (designated as CBR-1 through CBR-4) were drilled within the proposed construction areas. Specifically, borings B-1 and B-2 were performed within the proposed school footprint and borings B-3 through B-12 and CBR-1 through CBR-4 were performed within the proposed residential construction area. The SPT borings were performed utilizing mud -rotary drilling techniques with a truck - mounted drill rig. Standard Penetration Tests (SPT) were performed in the field in general accordance with ASTM D 1586. The tests were performed continuously from the existing ground surface to a depth of 10 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 Ib. hammer falling 30 inches. The numberof 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. 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. Following the completion of each boring, the bore holes were backfilled with grout as required by NCDENR regulations. Additionally, a total of four (4) bulk soil samples were collected from the approximate pavement subgrade elevation in the vicinity of borings CBR-1 through CBR-4. The bulk subgrade samples were collected from beneath the existing surficial organic soils at depths ranging from 0.5 to 2 feet below existing grades. The bulk soil samples were returned to our laboratory and subjected to CBR testing in accordance with ASTM standards. The boring locations were located and staked in the field by a representative of G E T Solutions, Inc. The approximate boring locations are shown on the attached "Boring Location Plan", (Appendix 1). 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 staff Geotechnical Engineer -In -Training in accordance with ASTM D2488. A total of eight (8) representative split spoon soil samples were selected and subjected to natural moisture and 4200 sieve wash testing and analysis in order to corroborate the visual classification of the granular soils. These test results are tabulated on the following page and are also presented on the "Boring Log" sheets (Appendix II).

A summary of the CBR test data and the moisture density relationship curves (Proctors) are presented in Appendix IV. 3.0 SITE AND SUBSURFACE CONDITIONS 3.1 Site Location and Description The project site is located along the south side of Brewster Boulevard just west of the intersection with Stone Street in the Camp LeJeune military installation in North Carolina. Specifically, the project site is bordered to the east by a wooded area followed by an existing recreational area associated with an existing school, to the north by Brewster Boulevard followed by a wooded parcel, and to the west and south by a wooded parcel. The proposed project site currently consists of a wooded parcel with an existing dirt roadway bisecting the site and an open agricultural area located "ithin the east portion of the site. 3.2 Site Geology The project site lies within a major physiographic province called the Atlantic Coastal Plain. Numerous transgressions and regressions of the Atlantic Ocean have deposited marine, lagoonal, and fluvial (stream lain) sediments. The regional geology is very complex, and generally consists of interbedded layers of varying mixtures of sands, silts, clays and marine shell deposits. Based on our review of existing geologic and soil boring data, the geologic stratigraphy encountered in our subsurface explorations which generally consisted of marine deposited sands, silt and clays of the Belgrade Formation. 4 "Solutlons, nc,, Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G 3.3 Subsurface Soil Conditions The results of our soil test borings indicated the presence of topsoil material at each boring location ranging in thickness from 2 to 24 inches. Underlying the surficial organic materials (Topsoil) and extending to the boring termination depths of 10 and 25 feet below existing site grades, the natural subsurface soils were generally uniform throughout the site. These soils were noted to be primarily granular in nature and classified to consist of SAND (SP, SP-SM, SM, SC-SM, SC) with varying amounts of silt and clay. The Standard Penetration Test (SPT) results, N-values, recorded within these granular soils ranged from 2 to 36 blows -per -foot (BPF), indicating a very loose to dense relative density. Deposits of CLAY (CL, CH) were encountered within the subsurface granular soils between varying depths ranging from 0.25 to 6 feet and 18 to 25 feet below the existing site grade elevations at the location of borings B-1, B-2, B-6, B-7, B-10, and CBR-3. The subsurface description is of a generalized nature provided to highlight the major soil strata encountered. The records of the subsurface exploration are included in Appendix II (Boring Log sheets) and in the Generalized Soil Profile presented in 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. 3.4 Groundwater Information The groundwater level was recorded at the boring locations and as observed through the relative wetness of the recovered soil samples during the drilling operations. The initial groundwater table, where encountered, was determined to occur at depths ranging from 7 to 11.5 feet below current grades at the boring locations identified as B-1 through B-12 at the time of our site reconnaissance. The groundwater level was not encountered at the hand auger boring locations identified as CBR-1 through CBR-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. Perched groundwater levels are anticipated to occur throughout the site as a result of potential restrictive soil layers noted to consist of SAND (SC, SC-SM) and/or CLAY (CL, CH) encountered at a majority of the boring locations at depths ranging from 0.2 feet to 6 feet. D E C E O V E D AUG 2 12009 Dwa PROJ # Solutions, Inc. Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G 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, side walks, etc.). In the project's area, seasonal groundwater fluctuations of± 2 feet are common; 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, if necessary. 4.0 EVALUATION 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 areas should be cleared by means of removing all trees, surface vegetation, root mat, and topsoil or any otherwise unsuitable materials. It is estimated that a cut of about 6 to 8 inches in depth, with isolated areas of about 24 inches (such as B-4 and B-9) will be required to remove the topsoil materials. This cut is expected to extend deeper in isolated areas to remove deeper deposits of 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. The soils noted directly below the surficial organic materials (Topsoil) within the vicinity of borings CBR-2, CBR-3, B-4, B-7, B-9, and B-10 were noted to contain appreciable amounts of fines (SAND; SC, SC-SM and/or CLAY; CL, CH). The current (natural) moisture contents of the surface soils at the explored locations were estimated to be near or above their optimum moisture. 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 very soft soils may be required. The extent of the undercut will be determined in the field during construction, based on the outcome of the field testing procedures (subgrade proofroll). 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. SoludonsJncf.,,,i,,,VM Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G Due to the potential for perched water and the presence of moisture sensitive soils near the surface, control of surface water is very important to the successful completion of the proposed construction. The contractor should plan his grading activities to control surface water and minimize erosion of exposed cut or fill material. This may include constructing temporary berms, ditches, flumes and/or slope drains to intercept runoff and discharge it in a controlled fashion, while complying with state and local regulations. 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 or his representative 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 or his representative. Subsequently and prior to the placement of any select fill materials, compaction tests should be performed on the existing subgrade soils within the proposed building and/or pavement footprints in order to verify that they have been compacted to at least 95% of the Modified Proctor (ASTM D1557). It is possible that some subgrade improvements will be required to provide suitable soils for foundation, slab, and/or pavement support. Preliminarily, unstable pavement and/or slab -on -grade subgrade soils are anticipated to be corrected by means of undercutting the subgrade soils, where necessary, to a depth of about 12 to 18 inches and backfill the resulting excavations with suitable select fill materials. Similarly, in the event that unstable foundation bearing soils are encountered it is anticipated that an undercut depth of about 1 to 2 feet and subsequent backfill with suitable select fill materials will result in suitable bearing conditions. Recommendations concerning the subgrade improvements (as necessary) should be more accurately determined in the field following the testing procedures as conditions are anticipated to vary. The project's budget should include an allowance for subgrade improvements (undercut and backfill with structural fill). 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 25% by weight of fines (SP, SM, SW, GP, GW), 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. �ECEIV ED AU0 2 1 2009 Solutions, Inc. _� DWO PROJ F -- Report of Preliminary Subsurface Investigation 8 Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G Other soils types such as SAND (SC-SM, SC) and/or CLAY (CL) may be used as fill provided that they are properly placed and compacted as noted herein. These soil types are typically moisture sensitive and unstable conditions and/or the inability of the materials to be properly compacted may occur. Accordingly, should these soils be selected for use as fill it is considered necessary to allow them to be dried to a moisture content suitable for placement and compaction. 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 should be placed in 4 to 8 inch loose lifts when compacted with the use of hand operated equipment and should be compacted to at least 95 percent of ASTM D1557. 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 Suitability of On -site Soils The subsurface CLAY (CL and CH) and/or SAND (SC and SC-SM) soils encountered at the boring locations do not appear to meet the criteria recommended in this report for reuse as structural fill, but may be used as fill within green areas. However, the SAND (SM, SP-SM, and SP) soils may be suitable 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 substantiate the suitability of excavated soils for reuse as fill within construction areas. 4.5 Preliminary Foundation Design Recommendations Provided that the construction procedures are properly performed, the proposed structures can be supported by shallow spread footings bearing upon firm natural soil, 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. (Solutions; ;Inc ,; 'Mi Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G In order to develop the recommended bearing capacity of 2,000 pounds per square foot (psf), the base of the footings should have an embedment of at least 18 inches beneath finished grades and wall footings should have a minimum width of 20 inches for the proposed residential structures and 24 inches for the proposed elementary school and community center. 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 18-inch footing embedment is considered sufficient to provide adequate cover against frost penetration to the bearing soils. Alternatively, post -tensioned slab construction may be utilized to support the proposed residential structures. The post -tension slab foundations should be sized by the structural engineer. A subgrade modulus of 125 psi/in for compacted structural fill can be used in the design of the post -tensioned slab foundations. 4.6 Settlements It is estimated that, with proper site preparation, the maximum resulting total settlement of the proposed building foundations should be up to 1 inch. 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). The settlements were estimated on the basis of the results of the field penetration tests. Careful field control will contribute substantially towards minimizing the settlements. 4.7 Foundation Excavations In preparation for shallow foundation support, the footing excavations should extend into firm natural soil or well compacted structural fill. The foundation bearing capacities should be verified in the field during construction by means of performing an inspection of all footings. At that time, the Geotechnical Engineer or his representative will explore the extent of excessively loose, soft, or otherwise unsuitable material within the exposed excavations. Also, at the time of the footing observations, the Geotechnical Engineer or his representative should determine and perform the necessary testing and evaluations to further evaluate the foundation bearing soils. 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" 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. Solution Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321G Immediately prior to reinforcing steel placement, it is suggested that the bearing surfaces of all footing and floor slab areas 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 foundation may be waived by the Geotechnical Engineer, where firm bearing soils are observed during the foundation 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. 4.8 Slab -on -Grade Design The floor slabs may be constructed as slab -on -grade members provided the previously recommended earthwork activities and evaluations are carried out properly. It is recommended that all ground floor slabs be directly supported by at least a 4-inch layer of relatively clean, compacted, poorly graded sand (SP) 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 noted that all ground floor slabs may consist of "floating" slabs that are ground supported and not rigidly connected to walls or foundations. Alternatively, monolithic slab - on -grades with turn down foundations may be used. The slab -on -grade subgrade should be established by means of placing the recommended structural fill and compacting to at least 95% of the Modified Proctor maximum dry density (ASTM D 1557). This construction procedure will provide a subgrade modulus of at least 125 psi/in. 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 orother 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. n Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G 4.9 Pavement Design The California Bearing Ratio (CBR) test results indicated soaked CBR values ranging from 14.1 to 17.9, averaging 15.7. 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 10.5 was used in designing the pavement sections. Furthermore, the Average Daily Traffic (ADT) loading criteria provided by Kimley-Horn and Associates, Inc. and the information listed below were also used to complete the pavement design analysis, which was performed in accordance with AASHTO requirements. Should any of the information below be incorrect G E T Solutions, Inc. should be notified to perform a subsequent analysis prior to paving operations.

Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G The results of the pavement design analysis are included in Appendix V (Pavement Design Analysis). All pavement material and construction procedures should conform to Unified Facilities Criteria (UFC) and 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. 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 500x or equivalent). These alternatives are to be addressed by the Geotechnical Engineer during construction, if necessary, who will recommend the most economical approach at the time. 4.10 Seismic Evaluation It is noted that, in accordance with the INC 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 25-foot deep SPT borings as well as our experience with SPT borings and CPT soundings with shear wave velocity testing performed within the vicinity of this project site. In order to substantiate the site classification provided above a 100-foot deep CPT boring and soil shear wave velocity testing with liquefaction potential analysis should be performed. G E T Solutions, Inc. would be pleased to provide these services should they be determined necessary. 4.11 Soil Permeability At this time saturated hydraulic conductivity testing was not included in our scope of services. However, in order to assist with the storm water design, estimated permeability values of the subsurface soil conditions encountered at the completed boring locations are provided in Table III. Should a more accurate groundwater level be required, G E T Solutions, Inc. can install a series of ground water monitoring wells when we re -visit the project site to perform field saturated hydraulic conductivity testing. 12 Solutions, Inc ,_i Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321G Table III - Estimated Permeability Values Soil Classification Percent Silt and/or Clay Estimated Permeability Rate SP, SP-SM 0% to 15% 1.0E-03 cm/sec SM, SM-SC 15% to 30% 1.0E-05 cm/sec SC 30% to 50% 1.0E-06 cm/sec CL 50% to 70% with Liquid Limit less than 50 1.0E-07 cm/sec CL, CH 70% to 100% 1.0E-07 cm/sec 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. If water collects in foundation excavations, it will be necessary to remove the water form the excavation, remove the saturated soils, and re -test the adequacy of the bearing surface soils to support the design bearing pressure prior to concrete placement. Perched water table conditions within the select fill materials and/or shallow subsurface soils may be encountered throughout the project site during periods of heavy precipitation and/or during the "wet' season. This is expected to occur as a result of the surficial restrictive soil layers (CLAY: CL, SAND: SC, SC-SM) that were encountered at the location of borings B-1 through B-4, B-6, B-7, B-9, B-10, B-12, and CBR-1 through CBR-4 at depths ranging from 0.2 feet to 6 feet. Accordingly, some undercut and backfill with suitable structural fill materials and/or de -watering of the structural fill materials and/or shallow subsurface soils may be required during the subgrade preparation and/or foundation construction procedures. Alternatively, an under drain system may be used in order to aid in alleviating the potential for saturated bearing soil conditions and/or to aid in minimizing foundation undercutting procedures. 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. Again, we recommend that the contractor determine the actual groundwater levels at the time of construction to determine groundwater impact on this project. 13 Solu[lons, Inc. Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G 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 a suitable bedding. This stabilization is typically accomplished by providing additional bedding materials (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. 5.3 Additional Geotechnical Investigation A comprehensive geotechnical investigation is recommended once the final layout (structure footprints and design grades), structural characteristics, and the structural loads are determined. The subsurface data documented during this feasibility study can be incorporated within the final geotechnical investigation. Specifically, it is recommended to perform additional SPT borings and/or DMT Soundings within the limits of the proposed commercial building areas along with a comprehensive laboratory testing program. Furthermore, it is recommended to perform CBR tests within the pavement areas to provide pavement design parameters. The frequency of tests should be developed based on the final design scheme. 5.4 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. 14 WN Solutions, Inc. :'i Report of Preliminary Subsurface Investigation & Geotechnical Engineering Services October 14, 2008 Camp LeJeune Family Housing — Feasibility Study Camp LeJeune, North Carolina G E T Project No: EC08-321 G We are providing this information solely as a service to our client.

Appendix C OVERVIEW Backeround This report contains the approach and preliminary results of a stormwater impact analysis conducted for the proposed Camp Lejeune Phase I Development. The project site is located at Marine Corps Base (MCB) Camp Lejeune in Onslow County, North Carolina. The project site is on approximately 170 acres bounded by Brewster Boulevard to the North, cast of Paradise Point Golf Course, and west of Stone Street as shown in Appendix A: Vicinity Map. The proposed project is Phase I of six proposed phases of development at Camp Lcjcunc. An Environmental Assessment (EA) of the master development was completed by the United States Marine Corps in accordance with the National Environmental Policy Act (NEPA). Pursuant to this report, A Finding Of' No Significant Impact (FONSI) was issued in August 2008. Existine Conditions The proposed project site is currently an undeveloped, wooded area. There is a narrow dirt road running from the northeast corner of the project site in the southwest direction. A review of the topographic survey shows grades on the site ranging from elevation 14 to elevation 30. A preliminary geotechnical investigation was completed in August 2008. An executive summary of the results is attached in Appendix D: Preliminary Geotechnical Investigation. Ill. Wetlands and Waters of the United States A wetland delineation of the proposed project area was confirmed by the United States Army Corps of Engineers on March 2009. The Notification of Jurisdictional Determination is attached in Appendix E. Less than 0.1 of an acre of wetlands will be impacted due to underground utilities associated with the proposed development. There arc no Waters of the Unites States on the proposed project site. IV. Proposed Development The proposed project includes the development of 340 family housing units for enlisted military personnel, one community center, one Department of Defense Education Activity (DoDEA) School, and connecting right-of-ways. The layout of the proposed project is shown in Appendix B: Proposed Site Plan. Five interconnected wet detention basins will serve the residential development site to treat stormwater runoff and one wet detention basins will serve the school development site to treat stormwater runoff. The proposed project is on approximately 170 acres, of which approximately 128 acres will be disturbed. The post -development impervious area of the proposed development was calculated to be approximately 34% or 57 acres. The proposed development is Phase I of a master development including six phases. It is anticipated that future phases of development will require additional stormwater infrastructure. The layout of the proposed master development is shown in Appendix C: Proposed master Development. ®ECE111E� AUG 21 2009 DWQ V. Stormwater Analvsis Onslow County is a coastal county located within the White Oak River Basin. Thus, stormwater management measures shall be designed in accordance with the Coastal Stormwater Rules Session Law 2008-2 1I. The proposed project area drains to the Morgan Bay, Index Number: 19-18. According to North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Quality the proposed project drains to SC waters. The build upon area is greater than 24%; therefore, the proposed project is considered High -Density. Per the stornnvater quality requirements, the first 1.5" of rain must be stored, controlled, and treated for 85% of the Total Suspended Solids (TSS). If wet ponds are used as a Best Management Practice (BMP) the temporary pool most 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. 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 information further revealed three main stormwatcr egress points, each of which has a significant drainage area composed of lands that are both a part of and separate from the proposed project site. 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. Structural measures will be required for conveying and controlling increases in stormwater runoff directly related to the increase in impervious area due to the Camp Lejeune development. These measures will be designed to meet both the quantity and quality requirements for the State of North Carolina as described in Section V. 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 the on -site wet ponds. Five interconnected wet ponds have been designed to control and treat stormwater runoff front the residential development and one wet pond BMP has been designed to control and treat stormwater runoff from the school development. The locations of the proposed ponds are illustrated on Appendix C: Proposed Site Plan. The five interconnected wet ponds controlling and treating runoff from the residential development will outfall into an unnamed ditch on the south west corner of the subject property. This unnamed ditch flows to an existing culvert under Eden Street and outfalls into Morgan Bay, an arm of the New River. The wet pond controlling and treating runoff from the school development will outfall into an unnamed ditch on the west side of the subject property. This unnamed ditch flows to an existing culvert under a dirt road and outfalls into Morgan Bay, an arm of the New River. The stormwater networks and wet ponds will treat runoff from the entire project area with exception to approximately 3 grassed acres on the north boundary, which will sheet Flow to existing culverts on Brewster Boulevard. The proposed ponds will have a combined footprint area of approximately 8 acres (normal water surface area). They are expected to have a minimum of 3:1 side slopes with a 10' wide aquatic bench with 10:1 side slopes. The bottom elevations are expected to be 5.0' below the normal water surface elevation for all the proposed ponds. The volume between the pond bottom and the normal pool is considered the water quality or permanent pool volume. The volume above the normal pool elevation is for water quantity (stormwater management). Based on the existing wetland areas and groundwater information, we expect the normal water surface elevations can be maintained by the groundwater. The existing and proposed drainage systems will be 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 will also be used in the design of the proposed stormwater system. A Manning's n value ol'0.013 will be used for the storm sewer pipe. VII. Erosion Control Erosion and Sedimentation control measures shall be designed in accordance with 15A NCAC, Chapter 4 (NC Sedimentation Pollution Control Act of 1973). The project site will be surrounded by silt fence and all existing and proposed stormwater structures will be fitted with inlet protection devices to prevent sediment from exiting the project site. The proposed ponds are anticipated to act as temporary sediment basins during construction.
