The project site is located in New Hanover County along to the Cape Fear River in Wilmington, North Carolina north of the intersection of USS North Carolina Road and Battleship Road. The USS Battleship project is to construct a service park to provide parking and walking access to the USS battleship. This project includes a parking lot at the east section, a future parking lot at the west section, walkway access to the USS Battleship, and a pedestrian bridge above a proposed tidal creek between the parking lots. Currently, the project site is partially developed and covered with asphalt pavement, grass and trees. 2.0 SCOPE OF INVESTIGATION The Project Scope included the following tasks. • Coordinate subsurface utility locate by NC 811 and Battleship personnel at proposed testing locations. • Advance 19 Cone Penetration Test (CPT) soundings. • Advance four (4) Direct Push Technology (DPT) soil borings. • Collect two (2) bulk samples. • Survey CPT, DPT, and bulk sample locations. • Conduct laboratory testing. • Geotechnical engineering analysis, recommendations, and reporting 3.0 FIELD EXPLORATION Catlin Engineers and Scientists (CATLIN) conducted the field exploration for this project between December 11t" and the 291"2020. Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 1 February 2021 Coordinates of proposed testing locations were determined using a georeferenced site plan provided by Moffatt and Nichol. Coordinates were input into a mapping grade (less than three horizontal feet accuracy) global positioning system (GPS) which was utilized by CATLIN personnel to physically mark the proposed testing locations. NC ONECALL associates and Battleship personnel were contacted to "clear" the proposed testing sites with relevance to underground utilities. Subsequent to completion of the testing, the ground surface elevation and location of each boring was collected using a real time kinematic (RTK) GPS. All units are recorded to the nearest foot horizontally using the North Carolina State Plane (NCSP) North American Datum 1983 (NAD83) coordinate system and one tenth of a foot vertically on the North American Vertical Datum 1988 (NAVD88). Testing locations are presented on Figure 2. Testing location NCSP NAD83 coordinates and NGVD88 elevations are presented on sounding and boring logs included in Appendix A. 3.1 Cone Penetration Testing Sixteen CPT probes were advanced in general accordance with the American Society of Testing Materials (ASTM) Method D-5778 with a track -mounted CPT rig equipped with a Vertex electronic piezocone tip. The cone was pushed at a rate of 0.8 inches per second (in/sec). The piezocone had a base area of 1.6 square inches, a diameter of 1.4 inches, and a height of 1.2 inches corresponding to a 60' apex angle. The friction sleeve to which the cone was attached had a 1.4-inch diameter. Data collected from the CPT soundings includes cone tip resistance, sleeve friction resistance, and pore water pressure. Soundings were advanced to the proposed target depths or until equipment refusal occurred. Equipment refusal (CPT refusal) was encountered when the reaction force of the CPT (approximately nine (9) tons) was determined to be less than the force applied on the tooling string resulting in a physical "lift" of the CPT machinery. Data generated during the soundings was processed by CATLIN personnel using Coneplot CPT Processing software (Version 2.6.3) then post processed using gINT Geotechnical and Geoenviron mental software (Connect Edition Version 10.00.00.50) to facilitate generation of Sounding Reports and Subsurface Profiles. Testing locations are presented on Figure 2 and CPT Sounding Logs are presented in Appendix A. 3.2 Direct Push Technology Borings Four (4) DPTs were advanced by CATLIN personnel immediately (within three horizontal feet) adjacent to four (4) existing CPT locations. The DPT borings were advanced to facilitate soil sample collection for physical descriptions and laboratory analysis to corroborate CPT software soil behavior type (SBT) interpretation. Direct push borings were advanced with a Geoprobe sampling system mounted on CATLIN's CPT machine. Samples were collected in four -foot intervals by advancing the dual tube sampling tooling Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 2 February 2021 using a combination of a percussion hammer, machine reaction force, and hydraulics. Subsequent to each four -foot tooling advancement, the inner rods and sample collection tube (acetate liner) was removed, labeled, and stored for processing and logging at CATLIN's Wilmington office. DPT Boring Logs are presented in conjunction with the adjacent CPT soundings in Appendix A. 3.3 Bulk Sample Collection Two (2) bulk samples were collected within the limits of the proposed parking area. These soils were collected using a manual auger, sealed in labeled 5-gallon buckets, and transported to CATLIN's Soil Laboratory in Wilmington, North Carolina forfurther analysis. 3.4 Groundwater Measurement and Borehole Abandonment Groundwater levels across the project site were estimated from pore pressure readings obtained during the advancement of the CPT soundings and measured, where possible, in the open boreholes subsequent to advancement of the CPT. Estimated and measured depth to water ranged from 1.3 to 4.3 feet BLS which roughly corresponds to the observed levels of the Cape Fear River during the investigation. It is likely that these water levels will be tidally influenced and fluctuate relative to the water level of Cape Fear River. Observed groundwater depths are presented on the CPT Sounding Logs in Appendix A and the subsurface profiles on Figures 3 through 5. 4.0 LABORATORY TESTING Ten soil samples were collected from the DPT borings and submitted to CATLIN's Geotechnical Laboratory in Wilmington, North Carolina for one or more of the following analysis: Test Description Test Method Engineering Soil Classification ASTM D 2487 Sieve Analysis ASTM D 6913 Atterberg Limits (Multi Point) ASTM D 4318 Soil Moisture Content ASTM D 2216 Organic Content ASTM D 2974 Two (2) bulk samples were collected from the subject site and submitted to CATLIN's Geotechnical Laboratory for the following analysis: Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 3 February 2021 Test Description Test Method California Bearing Ratio (1 Point) ASTM D 1883 The results of the geotechnical laboratory analyses were utilized to refine the visual classifications of the site soils, correlate the CPT interpreted soil type with site soils, and provide geotechnical characteristics of the soils. Results of the laboratory testing performed during this investigation are included in Appendix B. 5.0 REGIONAL, LOCAL, AND SITE GEOLOGY According to the Geologic Map of North Carolina (1985), the project site lies within the Coastal Plain Physiographic Province of North Carolina. According to Horton and Zullo in The Geology of the Carolinas (1991), the Coastal Plain is comprised of a seaward thickening wedge of post -Triassic, primarily unconsolidated, siliciclastic sediments and carbonate rocks that extend from the Fall Line to the continental shelf break. Coastal Plain sediments were deposited in a number of different environments including but not limited to, off -shore marine, near -shore marine, lagoonal, and deltaic. The eustatic rise and fall of sea level has resulted in numerous sedimentary packages of transgressive and regressive sequences deposited throughout the Coastal Plain. According to the USGS Online Spatial Data website, the primary geologic formations found in New Hanover County, North Carolina include: • Undifferentiated Coastal Plain deposits (Quaternary) - Comprised primarily of alluvial, eolian, fluvial, and lacustrine deposited marine sediments consisting of gravel, sand, silt, and clay. • Castle Hayne Formation (Tertiary) - limestone with solution cavities common. New Hanover Member exhibits phosphate -pebble conglomerate with micritic thin layers. • Peedee Formation (Cretaceous) - primarily unconsolidated greenish gray to olive black, clayey sand and clay which may be locally fossiliferous and calcareous Land surface at the site is covered with asphalt pavement and grass with elevations at the testing locations ranging from 1.7 to 4.4 feet. Data generated during this investigation identified three (3) primary strata extending to an elevation of approximately minus 20 feet. Material encountered from land surface to an average elevation of zero was identified as "recent" fill likely emplaced shortly prior to the construction of the battleship facility. The recent fill was described as light brown to gray consisting of fine to coarse sand and silty sand. A substantial amount of CPT SBT interpretation through this stratum was reported Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 4 February 2021 as "Out of Range" which along with increased tip pressure readings indicates that this material is likely to consist of dense coarse sand and gravel. Sand, gravelly sand, and silty to clayey sand interbedded with moderately to highly organic silt and clay rich layers extends from beneath the recent fill to elevations ranging from roughly -4 to -10 feet. The origin of this material is unclear as it appears to be a mixture of "historical fill" that may have been emplaced during the early periods of the development of Wilmington and the associated riverfront industries and alluvial overwash which has likely occurred during the many flooding events that have occurred through the site's history. CPT and DPT refusal was encountered at elevations ranging from approximately -3 to -8 feet in soundings and borings advanced adjacent to the river indicating that large fill debris may exist in the subsurface in this vicinity. Highly organic (organic content values ranging from 28.5% to 49.1 %) alluvial silt and clay with wood fragments was encountered beneath the historical fill to an average elevation of minus 20 feet. This organic material appeared to be very soft with little to no tip or sleeve resistance indicated in the CPT data. Sands and sand mixtures with thin layers of clays and organics (as indicated by the CPT SBT) extend from below the highly organic silts and clays to elevations ranging from -31.6 feet and -34.2 feet where CPT refusal was encountered in soundings CPT-09 and CPT-08, respectively. Based on relatively rapid increase in tip resistance noted in the CPT soundings, the refusal is likely due to the presence of limestone. Subsurface profiles are presented on Figures 3 through 5. CPT and DPT logs are included in Appendix A. 6.0 SUMMARY RECOMMENDATIONS The conclusions and preliminary recommendations presented in this report are based on the project description and soil data obtained from our field and laboratory testing, CPT sounding data, assumed continuity of the soils between borings, and generally accepted geotechnical engineering practices. The borings/soundings performed at this site represent subsurface conditions at the location of the borings/soundings only; therefore, undisclosed subsurface conditions requiring special preparation may be revealed during construction, especially for those proposed structures located significant distances from our soil borings. Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 5 February 2021 6.1 Pavement Design 6.1.1 California Bearing Ratio Testing The California Bearing Ratio (CBR) test is a penetration test used to evaluate the subgrade strength of roads and pavements. A total of two (2) composite soil samples were obtained from approximately 0 feet to 4 feet BLS at four (4) boring locations within the proposed parking lot and driveway areas. These soil samples were brought to the CATLIN Soil Laboratory for testing in accordance with the 1-point CBR test procedures outlined in ASTM D 1883. In the 1-point CBR test, the soil samples will be compacted using 56 blow counts per layer. The CBR test results are shown in the Table 1 below and included in Appendix B. The results of these tests are used with the curves to determine the thickness of pavement and its component layers. Typically, CBR of soils decreases as moisture content increases above the optimum moisture content. Soil types have different effects on CBR as well, often related to their particle size; sandy soils generally have high CBR, while saturated fine-grained soils (clays and silts) have low CBR. Table 1— CBR Test Results BORING POINT ID Blows Per Layer Corrected CBR @ 0.1" (%) Corrected CBR @ 0.2" (%) CBR 01 — CBR-01-01 56 9.2 11.2 CBR-01-02 56 9.2 11.2 CBR-01-03 56 11.9 14.8 CBR-01-04 56 7.8 10.6 CBR 02 CBR-02-01 56 7.8 8.9 CBR-02-02 56 12.5 16.2 CBR-02-03 56 9.9 9.5 Refer to the laboratory results in Appendix B for more detail on the results of the CBR testing. 6.1.2 Pavement Thickness Recommendations Based on the subsurface information and anticipated vehicle loads at the site, we recommend the following minimum thickness for the parking lots: Heavv Dutv Bituminous Concrete Pavement Section (Driveways) • 1.5 inches NCDOT HMA Surface Course Type S9.5C • 2.5 inches NCDOT Intermediate Course Type 19.00 • 8 inches NCDOT Aggregate Base Course • Stabilization Geotextile (AASHTO M288 Class 1 Woven, elongation <50%, Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 6 February 2021 seams overlap 24" min.) Light Duty Bituminous Concrete Pavement Section (Parking Stalls) • 3 inches NCDOT HMA Surface Course Type S9.5C • 8 inches NCDOT Aggregate Base Course • Stabilization Geotextile (AASHTO M288 Class 1 Woven, elongation <50%, seams overlap 24" min.) Concrete Walkway Pavement Section • 4 inches Portland Cement Concrete • 4 inches NCDOT Aggregate Base Course 6.2 Pedestrian Bridge End Bents Foundation Recommendations — Driven Pile 6.2.1 Driven Pile Capacities Based on the current site conditions and anticipated structural loading, CATLIN recommends that the proposed end bents of the pedestrian bridge be supported on either HP 12x53 Piles or 10-inch to 12-inch diameter timber piles. The pile vertical and lateral capacities and estimated settlement under loadings equal to the allowable compressive capacities are shown in Table 2 below: Table 2 — Driven Pile Capacities Pile Penetration Depth, BLS (Tip Elevation) (ft) Allowable Compressive Capacity (kips) Allowable Uplift Capacity (kips) Settlement (in.)

The capacity values provided by the US Army Corps of Engineers Method were selected as the design ultimate capacities. A factor of safety (FS) of 2.0 was used for the allowable compressive capacity determination and a factor of Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 7 February 2021 safety of 3.0 was used for the allowable uplift capacity determination. Lateral capacities for the piles were calculated utilizing LPILE analysis. The allowable lateral capacities were determined under the criteria that the allowable horizontal fixed head deflection is'/4 inch. The axial thrust utilized in the lateral analysis is equal to the allowable axial compressive load corresponding to the pile length used (see previous table for values). Larger axial thrust values may reduce lateral capacities. 6.2.2 Driven Pile Spacing The individual pile capacities within a pile group will be reduced if the piles are installed too close to each other since the stress that transmitted from pile to the soil will overlap. In order to prevent a reduction in axial capacity due to "group effect", piles should be installed with a minimum center -to -center spacing of 3 times of pile side dimensions. 6.2.3 Construction/Installation Considerations It is recommended that two overlength test piles (at least 5 feet longer than anticipated production piles), or indicator piles, be driven to establish pile driving criteria, production pile lengths, and the need to auger pilot holes prior to driving for production piles. Test piles may be used as production piles if the required pile capacity is reached. Production piles should not be ordered until the length estimates have been determined and verified; however, the overlength test piles can be driven in the locations for production piles. Pile driving criteria and actual pile penetration depths shall be established during driving through dynamic testing with a Pile Driving Analyzer (PDA) and by applying the North Carolina State Building Code. All pile driving operations and static and dynamic testing should be observed by a soil technician working under the direction of a registered professional engineer. Static testing of the pile should be in accordance with ASTM D1143. The engineer should develop driving criteria for the project using both a wave equation analysis (once the contractor has designated the pile hammer to be utilized for driving) and results from dynamic monitoring of test piles with signal matching analyses (CAPWAP). The potential exists that the recommended pile penetration depths may not meet the respective minimum criterion in some areas, due to the generation of excessive pore pressures within the clay and/or silt strata during driving, causing a temporary loss of shear strength. Once these large pore pressures have dissipated (assumed to take 3 to 7 days), the soil should regain strength and the piles should gain bearing capacity, a phenomenon known as pile "set-up". Dynamic testing with a PDA should be performed during restrike of the test piles after a sufficient waiting period for pile "set-up" to occur. It is recommended that pile restrikes be performed 3 days after initial driving. Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 8 February 2021 6.3 Earthwork Operations 6.3.1 Site Drainage Due to the occurrence of shallow standing water in soils in some areas on site and their sensitivity to moisture arising from their fine texture, earthwork operations will be hampered by a tendency for exposed surfaces to degrade under traffic. Much of this degradation and the consequent need for subgrade repair or replacement can be obviated by the implementation of a system of overall site subgrade drainage. Standing water levels recorded in boreholes located near existing site drainage features suggest that ditching may be effective in depressing the level of shallow groundwater. Temporary site drainage ditches should follow the approximate routing of the designed stormwater drains and roadway swales. They should be deep enough to drain the in -place soils to a depth of at least two and one-half feet below the deepest cuts occurring in the grading scheme. It is possible that some additional and/or alternative temporary dewatering measures, such as well points or sumps, will need to be implemented for the foundation construction since some excavations may have to be maintained below the water table. 6.3.2 Site Preparation and Grading Site preparation should be initiated by clearing and grubbing the root systems of any trees occurring within the limits of construction and stripping surficial organic laden soil and surface vegetation. Surface stripping of up to approximately 6 inches over the undeveloped portion. Site preparation in areas of existing pavement to be demolished should consist of removal of pavement and aggregate base course (depending on plans for new parking/drive areas). To the extent possible, pneumatic -tired vehicles should be kept off areas exposed after stripping or exposed in cut. Where fill is placed, it should be end - dumped and spread with a bulldozer. Areas should be shaped to drain at the end of each workday or when rain is anticipated, as the on -site clays will readily degrade when saturated. Prior to backfilling, the exposed subgrade in these areas should be proof rolled with a heavy smooth -drum roller or a loaded tandem -axle dump truck to identify regions of yielding soil. Where such regions occur, the soils should be undercut to firm material and backfilled with controlled structural fill. Proof rolling should be observed by a qualified geotechnical engineer or his designated representative so that appropriate judgments as to the depth and extent of subgrade repair can be made. In areas that require undercut of Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 9 February 2021 soft, loose, saturated, yielding, and/or otherwise unsuitable soils, the horizontal dimensions of any removal and replacement measures should typically extend beyond the edge of the foundation (on all sides) a minimum of one half the depth of the excavation below the bottom of foundation. 6.3.3 Placement and Compaction of Fill As indicated above, structural fill should be end -dumped and spread with tracked equipment to avoid pneumatic -tire traffic on the sensitive on -site soils. In areas of deep cut or undercut, it may not be possible to effectively compact structural fill in lifts of ordinary thickness without degrading the underlying native soils. Accordingly, in these areas, placement of an initial "bridge" lift ranging from 12 to 18 inches in loose thickness will likely be necessary to provide a firm base for further placement and compaction of fill soils. This bridge lift should be compacted on its surface in accordance with the project specifications governing degree of compaction but should not be expected to meet those compaction requirements at a depth greater than four inches. Except as indicated above, structural fill should be placed in lifts not exceeding 8 inches in loose thickness and compacted to a minimum of 98 percent of their maximum dry density as determined by the Standard Proctor Method (ASTM D698) except where more stringent UFC or NCDOT compaction requirements govern. For this project, we recommend that structural fill consist of a relatively clean sand falling within USCS Soil Group "SP", "SP- SM", or "SP-SC". Soils falling within this classification when placed and compacted as outlined above are referred to herein as "controlled structural fill". 6.3.4 Utility Trench Backfill Trench backfill for underground utilities and piping should consist of crushed rock for pipe bedding material followed by quarry screenings or coarse sand in the remaining pipezone backfill (Type A). As a second option (Type B), crushed rock may be placed as bedding and extend to springline of pipe, followed by quarry screenings or coarse sand in the remaining pipezone backfill. For pipes and utilities within wet soils or below the water table, backfill should consist of a minimum of 6 inches of crushed rock below and to the sides of pipe, extending a minimum of 12 inches above the top of pipe, and encased in geotextile fabric (Type C). All trench backfill should be placed and compacted as recommended in Section 3.6.3 above. Native soils may be used to backfill the remainder of the trench, unless utility or pipe is to traverse beneath or within the influence zone of any foundations, in which case controlled structural fill shall be placed and compacted as stated below. Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 10 February 2021 For utility structures bearing in very soft clay or other unsuitable materials, the material should be undercut to a suitable depth as determined by the geotechnical engineer (anticipate 12 to 18 inches below pipe bearing elevation) and replaced with controlled structural fill or crushed/washed stone. Where crushed/washed stone is used and conventional compaction testing is not practical, material should be mechanically compacted until no further yielding is observed. If sand bedding material is to be used above crushed/washed stone, the stone layer should be wrapped in a non -woven geotextile separation fabric. All controlled structural fill should be placed and compacted to 95% of the ASTM D-1557 maximum dry density. 6.3.5 Suitability of On -Site Soils for Re -Use The native, near surface granular soils, such as the sand (SP), clayey sand (SC) or silty sand (SM) in the upper stratum, are considered suitable for re -use as foundation subgrade material, provided they are moisture conditioned to placed/compacted in accordance with the recommendations provided herein. The native, near surface fine-grained soils, such as fat clay (CH), sandy clays (CL) or sandy silts (ML) in the upper stratum, are generally not suitable for re -use as foundation subgrade material due to their poor strength characteristics and sensitivity to moisture. It is recommended that they be used within landscaped or other non-structural areas. In addition, any high plasticity clays/silts (CH, MH) or organic materials such as peat (PT, OL, OH), with liquid limits greater than 50 and plasticity indices greater than 20, should not be re -used as backfill placed directly below or against foundations or retaining walls. 6.3.6 Stability of Excavations Temporary slopes in shallow, open excavations above the water table may be adequately maintained at inclinations of no steeper than 1(H):1(V), although they should be evaluated by a geotechnical engineer during construction due to the relatively unconsolidated nature of Coastal Plain soils. The crests of all slopes should also be maintained at least 5 feet from any building or other structure limits. Temporary shoring or bracing of excavation sidewalls should be maintained for excavations that will extend below the water table, such as in the case of removing obstructions deeper than four feet BLS. Dewatering devices and/or site drainage techniques capable of maintaining a stable and surface -dry trench bottom should be provided. Battleship NC - Living with Water - Geotech CATLIN Engineers and Scientists CATLIN Project No. 220161 11 February 2021 7.0 LIMITATIONS This report and the subsurface investigation on which it is based in made for the purpose of study, planning, and design, and not for construction or pay purposes. General soil and strata descriptions and the indicated boundaries are based on a geologic interpretation of the available subsurface data and may not necessarily reflect the actual subsurface conditions between the test borings or between the sample intervals. The laboratory data and data collected in -situ is only as reliable as is inherent to the standard test method. Water levels and/or soil moisture conditions are reported as they were observed at the time of the investigation. These conditions can vary considerably from season to season and during times of extreme weather events. 8.0 REFERENCES Horton, J.
