Main Street Norfolk, VA 23510 YEW VIOLA ENGINEERING, PC RE: Executive Summary of Geotechnical Exploration Rivanna Village - Phase 2 Richmond Road, Albemarle County, VA Project No: PTL-172379 Mr. Culpepper: Winchester Office 402 Bufflick Road Winchester, VA 22602 Phone: 540-313-4270 Fax:540-434-0447 We have completed the subsurface exploration for the referenced project. Enclosed are geotechnical information and recommendations which include discussion of the site soils, depth to bedrock, and groundwater conditions as they relate to the design of pavement sections, construction, and foundation recommendations. In brief, the site is considered suitable for the planned development. Further, the site is underlain by low - plasticity silty sands with varying sand and gravel content trending to weathered phyllite bedrock at depths of approximately 5 feet. We expect that all site development can be achieved with conventional excavating equipment although some ripping may be required during utility and foundation installation. Excavated soil should be limited to use in general embankment/structural fill (USCS Classification: GM/SM) and will require amending for low seepage applications. We anticipate that drainage structures, bridges, and roadways will be constructed on a combination of cut and fill. Shallow foundation system for the bridges should be designed utilizing an allowable bearing capacity of 5,000 psf when bearing on approved concrete pads as discussed. Site soils are very dry and will require substantial moisture conditioning to achieve optimal moisture content for structural fill. Refusal was encountered in three (3) borings before obtaining the prescribed termination depth at 91 drilling sites (862.5 lineal feet of SPT and 430 lineal feet of probes). As such, we conclude that major rock excavation will not be required to develop Phase 2 as planned; although, some hoe -ramming may be required in isolated areas of buried utilities at depth. Although site conditions are very favorable for this project, we cannot stress enough the importance of adequate project oversight. All fill operations and subgrade preparation should be observed on a full-time basis, in accordance with Chapter 17 of the VCC and VDOT requirements by an authorized representative of the Geotechnical Engineer to confirm that compaction requirements and recommendations are being met.

The Phase 2 site is located east of Charlottesville, Virginia on US Route 250 and abuts to the Phase 1 of Rivanna Village located off Glenmore Way. Access internally between the phases of development will be provided by extension of Streamer Drive and Village Park Avenue of Phase 1 onto Lazy Branch Lane of Phase 2. The principal access to Phase 2 is planned off Route 250. This phase of development includes single-family dwellings, single-family attached villas, and single-family attached townhouses. In addition, Phase 2 includes the construction of seven roads which will be inducted into the VDOT inventory upon acceptance of construction. Roadway construction will include installation of bridges, retaining walls and box culverts. A park is planned within the limits of Block J, which also contains a walking trail, dog park, stormwater management structures and water features. According to plans developed by Alan Franklin PE, LLC, Rivanna Village - Phase 2 will incorporate an area of 63 acres. PROJECT AND SITE INFORMATION The site is largely wooded with stands of juvenile trees and some clear areas abutting Phase 1 and a small field associated with abandoned residential structures. A review of areal and satellite photography of the past 25 years indicates that most of the property has remained wooded and relatively undisturbed. Site topography ranges from elevation 400.00 to 342.00 (mean 361.10) with decreasing elevations trending through the central portion of the 63-acre parcel. Given the topographical relief of the site, the number of intermittent streams and wetlands become a major factor in site design. Figure 1. Site elevation overview. Albemarle Country Engineering indicates that all materials and construction methods shall conform to current specifications and standards of VDOT. This would include evaluating foundation conditions for all culverts of 30 inches in diameter and greater, relative retaining walls and bridges. Further, all roadways GEOTECHNICAL • GEOPHYSICAL CONSTRUCTION • MATERIALS AAA Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 Page 2 VE FIOL.a ENGINEERING, PC design and construction shall conform to VDOT Pavement Design Guide for Subdivision and Secondary Roads (Revised 2014). Current pavement section, as detailed in preliminary, are based on an assumed CBR values resulting in pavement sections with 6 to 8 inches of VDOT 2 1 A base stone under 5 inches of asphalt pavement. The detail for the pavement section for lane widening of Route 250 will consist of 9 inches of VDOT 21A base stone under 6 inches of asphalt or match existing pavement section if greater. These pavement sections, as detailed on Sheet 6 of the construction plans developed by Alan Franklin PE, LLC, will be evaluated utilizing worse case laboratory CBR values from representative subgrade samples acquired at finish subgrade elevation in the roadways of Phase 1 and the design ADT values listed on Sheet 4 of the construction plans. Please refer to Roadway and Parking Pavement Recommendations section for results of this evaluation. SITE EXPLORATION The site exploration was complex due to the location of several bridges, culverts and associated retaining walls relative to heavily wooded areas and wetland areas. As such, the site design dictates a total of three bridges and three culverts and approximately 1200 lineal feet of associated retaining walls to satisfy development requirements. Initial bridge and culvert locations were identified in the field by Blossom Consulting and Engineering Inc. In all, 18 test borings were drilled to ascertain subsurface conditions with continuous SPT testing (ASTM D1586) at all bridge and culvert sites. Furthermore, 18 test borings with continuous SPT were drilled at relative locations to ascertain subsurface conditions in areas that will support retaining walls (approximately 1200 lineal feet) associated with VDOT roadways. Standard penetration testing and sampling was continuous to a depth of 10 feet and at 5-foot intervals thereafter to refusal or termination depth per VDOT MOI Table 3-1 for bridge piers and abutments, and retaining walls supported on shallow foundations. In addition, auger probing was performed at 40 locations to ascertain the trend of hard bedrock depths relative to invert elevations of manholes and sewer piping. Relative manhole locations have been staked by Alan Franklin PE, LLC. Other locations of interest that required exploration included the wet pond expansion, with the possibility of using excavated material as embankment fill (test borings B-01, B-02, and B-03); the probable location of a wet swale depending on groundwater level (test boring B-05); and a potential borrow area on Cumbria Lane (test borings B-09a, b, and c). Please refer to the legend found in the lower right corner on the attached Test Boring Location Plan Sheets that relates the boring number of test borings, auger probes, and groups of test borings with the corresponding description of interest. Additional test borings to fulfill the minimum VDOT MOI requirements, other locations of interest, and auger probes to identify bedrock hardness trends along the alignment of sanitary sewers were GEOTECHNICAL • GEOPHYSICAL CONSTRUCTION • MATERIALS Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 Page 3 VE VIOLA ENGINEERING, PC located in the field by VEPC personnel with handheld global positioning equipment (GPS, SBAS, GLONASS) and are illustrated on the Test Boring Location Plan Sheets accordingly for reference. The soil test borings were performed in accordance with generally accepted geotechnical engineering practice using an ATV -mounted CME 55 rotary drill rig equipped with an automatic hammer. All test borings were advanced with 2.25 HSAs to predetermined depths with exception when attempting to core very dense weathered bedrock at bridge locations in test borings B-07c and B-08b. Rock coring was performed utilizing 3.25 HSAs. In brief, hollow -stem augers were advanced to sample intervals and representative soil samples were recovered with a standard split -spoon sampler (1%-inch ID x 2-inch OD) in accordance with ASTM D1586, the Standard Penetration Test. The standard dictates that a 140-pound weight freely drop from a height of 30 inches to drive the split -spoon sampler into the soil. The number of blows required to drive the split - spoon sampler through three consecutive 6-inch increments was recorded, and the blows of the last two increments are summed to obtain the Standard Penetration Resistance (N-value). Subsurface water level readings were taken in each of the borings during the drilling process and upon completion of drilling before backfilling with auger cuttings. The N-value provides a general indication of in -situ soil conditions and has been correlated with certain engineering properties of soils. An automatic hammer and safety hammer were utilized to perform the Standard Penetration Test (SPT) on this project. Research indicates that the Standard Penetration Resistance (N-value) determined by an automatic hammer is different than the N-value determined by the safety hammer method termed the N60 value or corrected value that negates the energy loss in the safety hammer method. The correction is made using the following equation: N60 = Nfield x CE The Nfiela value is recorded in the field and CE is the drill rod energy ratio for the hammer utilized in the field. The recommended correction factor (CE) of 1.5 is generally utilized to convert Naeld values to N60 values in accordance with typical published guidelines. The N-values reported on the Boring Logs and included in this report are the corrected values (N60). It is recommended that corrected N60 values be used for engineering analysis. GEOTECHNICAL • GEOPHYSICALAM CONSTRUCTION • MATERIALS <��t AA Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 Page 4 VE NIOL.A ENGINEERING, PC After refusal was encountered, rock coring was conducted at test boring B-07c and B-08b in accordance with ASTM D2113. An NQ sized wire -line coring system, utilizing water as a flushing agent, was used to obtain rock samples. The core barrel was advanced in 5-foot intervals, and samples were extracted and placed in a core box for transportation. Each core obtained was visually classified and assigned a rock quality designation (RQD) in accordance with ASTM D6032. The standard dictates that each core be visually examined to determine the length of intact rock with portions longer that four inches. Pieces of core that are moderately to intensely weathered, contain numerous pores, or are friable, or combination thereof, are not included in the RQD summation. The percentage of the summation of these intact portions of rock core compared to the overall core length is deemed the RQD number. Rock coring locations and depths were determined in the field to further characterized subgrade conditions. LOCAL GEOLOGY AND SUBSURFACE CONDITIONS According to the Digital Representation of the 1993 Geological Map of Virginia (2003), the planned development is underlain primarily by the Candler Formation. The unit consists of phyllite (Metaclastic) and schist (Metamorphic). Metaclastic formations form through sedimentation action and tend to be less durable than metamorphic rock which has undergone transformation by heat, pressure, or other natural processes. Further, phyllite is a fine-grain rock formed by the reconstitution of fine-grained, parent sedimentary rocks, such as mudstones or shales. Phyllite tends to split into sheets or slabs due to the parallel alignment of platy minerals as seen in Phase 1 construction. As reported, schist is medium grade metamorphic rock, formed by the metamorphosis of mudstone/shale or some types of igneous rock. The resulting foliation is coarser and more distinct due to the higher degree of crystallization of mica minerals. (i.e., biotite, chlorite and muscovite). As a result, schist is much harder than phyllite and requires more energy to excavate. The rock in the Candler Formation is typically referred to as shale because of its platy structure. Further, the strike of the weathered rock tends to the northeast and dips near vertically to the southeast. Results of rock coring in test borings B-07c and B-08b indicated very dense weathered phyllite with typical poor rock quality designation (RQD = 0). Note that auger refusal was not encountered in the weathered phyllite in test borings for bridges before achieving predetermined termination depth. According to the USDA Soil Survey of Albemarle County, the overburden consists of channery silt loam of the Mateo Channery and Nason silt loams (5113, 51C, & 62B). Reportedly, the major constituent of this unit is clayey and silty gravel with varying amounts of sand and fines with low shrink/swell capacity. Soil samples recovered in test borings indicate medium dense to very dense soil conditions (14 to > 60 blows GEOTECHNICAL • GEOPHYSICAL CONSTRUCTION • MATERIALS AA Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 Page 5 VE VIOLA ENCINEERIN(, PC per 12 inches) with an average N60 of 17 for intervals with less than 50 blows per foot (70 bpf globally). Site soils consist predominately of brown -red to tan -orange silty sand with varying fractions of sand and gravel trending to relic phyllite rock structures at depths of 5 feet or less. Liquid limit testing conducted from a bulk sample obtained from Boring B-09a, B-09b and B-09c indicates a low plasticity material with a liquid limit of 33 and plasticity index of 7 with a maximum dry density of 112.3 pcf at 15.5% optimum moisture, which is classified as silty gravel (USCS designation: GM). The corrected maximum dry density/optimum moisture due to 36% oversized fraction is 127.5 pcf at 10.5%. Moisture contents ranged from 1 to 34% with an average of 15% with the major portion of samples tested ranging from 5 to 10% with lower moisture content in samples obtained at depth. Therefore, excavated material at depth will require moisture conditioning in the field to achieve density requirements as specified to construct structural fill. The material at depth in the proposed borrow site investigated by test borings B-09a, B-09b, and B-09c is acceptable for use as mass structural fill with some limitations to tall slopes, however, will not be suitable for use as embankment material for ponds without amending to prevent excessive seepage. The subsurface conditions relative to the proposed expansion to the existing wet pond were evaluated with test borings TB-01, TB-02 and TB-03 at locations illustrated on the Test Boring Location Sheets. Test borings were extended to termination depths of 20 feet. The overburden soil ranges in depth from 3 to 5 feet and is underlain by dense weathered phyllite (N values > 50 bpi), which appears typical across the site. Based on our observations, we expect that the existing pond can be expanded as proposed without blasting. However, the excavated material is limited as embankment material (USCS Classification: GM/SM) without amending to restrict seepage. Sample refusal (>50 blows per increment) was encountered due to the presence of weathered relic rock structure with steep bedding planes typically at depths greater than 5 feet. Further, a large percentage of test borings and auger probes were terminated at predetermined depths without encountering refusal. Note that auger refusal was encountered in test boring B-05 at 12 feet. Auger refusal was encountered in auger probes conducted along the planned sanitary sewer lines at AP-13 and AP-16 at depths of 7 and 5 feet, respectively. Refusal in the auger probes occurred at or near the relative design invert elevation of the sewer system. Test boring B-05 was drilled in an area that is planned to be developed into a wet drainage swale. Given that refusal was encountered in three (3) borings before obtaining the prescribed termination depth at 91 drilling sites (862.5 lineal feet of SPT and 430 lineal feet of probes), we conclude that major rock excavation will not be required to develop Phase 2 as planned; although, some hoe -ramming may be GEOTECHNICAL • GEOPHYSICAL CONSTRUCTION • MATERIALS AA Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 Page 6 VE VIOLA ENGINEERING, PC required in isolated areas of buried utilities at depth. For detail information, please refer to the Test Boring Location Plan Sheets. GROUNDWATER Visual observation of soil samples can also be used to evaluate seasonal groundwater conditions. Soils that are periodically saturated will appear with gray muted colors (gleyed) or mottling due to changes in the oxidation state of iron, manganese and other trace minerals. In this geologic terrain a shallow water table usually develops near the surface of dense weathered bedrock. Groundwater tends to flow laterally along the soil/rock interface, generally mimicking topography. Further, groundwater in this topography is generally related to rainfall and thus intermittent in occurrence. Observations of groundwater were made after pulling the drill string at refusal or termination depth. Groundwater was encountered in several locations (test borings B-05 @ 12'; B-06a @ 20.5, B-06b @ 10.5'; B-06d @ 18'. B-06e @ 11'; B-06g @ 14'; and B-08a @ 11'). Test borings identified as B-06x were performed at the bridge location on Lazy Branch Lane at Mossy Rock Road. Although the groundwater was observed at depth, water intrusion during excavating for foundation construction may be problematic, especially during the wet seasons. Given the time of the year the test borings were performed; we do not expect that groundwater will be a substantial issue during construction in drier seasons. However, the surface soils will become inundated easily with frequent precipitation events that may cause delays in construction performed during the wet months of the year. CONSTRUCTION AND FOUNDATION RECOMMENDATIONS The following recommendations are based on visual and laboratory analysis of soil recovered from test borings typically drilled to termination or refusal depth. The subsequent sections are provided to aid the design engineers and site contractors in developing the site for its intended use. SUBGRADE PREPARATION AND EARTHWORK OPERATIONS Subgrade preparation should consist of stripping all vegetation, root mat, topsoil, asphalt, waste, and any other soft or unsuitable material from building areas. Roadway embankments may be stripped according to the latest revisions of the VDOT Road and Bridge Specifications. The site is covered with a nominal 8- inch topsoil layer. We recommend that earthwork clearing be extended a minimum of 10 feet beyond the building and pavement limits and an additional foot for each foot of fill required. Site excavation can be GEOTECHNICAL • GEOPHYSICAL CONSTRUCTION • MATERIALS AA Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 Page 7 VE VIOLA ENCINEERINC, PC performed with conventional earthmoving equipment. It is our opinion that blasting will not be required to effectively and efficiently excavate utility trenches if design finish subgrade is near or above existing grades. However, some hoe ramming will be required between auger boring locations and other sewer line alignments not investigated. All excavations shall be benched according to OSHA regulations to permit safe entry. Trench shoring for utility installation shall be designed by the Site Contractor's engineer utilizing OSHA Class C soil requirements for short term durations. After stripping to the desired grade, and prior to fill placement outside the limits of the building or structural pad, the stripped surface should be observed by an experienced geotechnical engineer or his authorized representative. Proof -rolling using a loaded dump truck with an axle weight of at least 10 tons may be used to identify localized soft or unsuitable material. Any soft or unsuitable materials encountered during proof -rolling should be removed and replaced with an approved backfill compacted to the criteria provided below. The subgrade should be moisture conditioned to within f3% of optimum moisture content and compacted to 95% maximum dry density (ASTM D698) prior to placing fill. Compacting the subgrade will reduce settlement within the building and parking areas. The finished subgrade elevation shall be compacted with a smooth drum roller prior to placing the stone work - surface. Any soil placed as engineered fill should be an approved material, free of organic matter or debris with a maximum limiting liquid limit of 50 and a maximum nominal particle size of 6 inches. This recommendation may be waived by the GER depending on location of engineered fill within the development. Unacceptable engineered fill materials include topsoil, organic materials (OH, OL), construction debris and large rock. All such materials removed during grading operations should be either stockpiled for later use in landscaped areas or placed in approved disposal areas either on or off site. Onsite materials are suitable for fill material excluding topsoil. All frozen soil should be removed prior to continuation of fill operations. Borrow fill shall not contain frozen materials at the time of placement. All frost -heaved soil should be removed prior to placement of fill, stone, concrete or asphalt. Site soils are moisture sensitive and may become unstable when exposed to prolong wetting as is typical during winter and spring months. As such, crushed aggregate or concrete with a nominal particle size of 4 to 6 inches may be mixed with site soils to produce a weather resilient soil matrix which can be utilized to prevent construction delay. Site soils are very dry and will require considerable moisture conditioning to achieve GEOTECHNICAL • GEOPHYSICAL CONSTRUCTION • MATERIALS AA Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 Page 8 VE FIOL A ENCINEERINC:, PC compaction requirements. The site contractor shall have means of providing water at all times during structural fill placement. Fill should be placed in lifts not exceeding 8 inches in loose thickness and moisture conditioned to within f3% of the optimum moisture content. We recommend that each lift be compacted to a minimum of 95% of the maximum dry density obtained in accordance with ASTM D-698 (or VTM-1), Standard Proctor Method. Test results included with this report should be considered a general guideline; additional testing of material shortly before fill operations commence should be performed to verify maximum dry density and optimum moisture content of actual fill material. All areas receiving fill should be graded to facilitate positive drainage and prevent ponding of water. The upper six inches of pavement subgrade shall be compacted to 100% of the maximum dry density in accordance with latest VDOT Specifications and Testing Procedures. There may be areas of the site that will receive large volumes of construction traffic over a short duration, and the exposed weathered bedrock subgrade may be pulverized and become unstable. We recommend that all affected areas be modified by undercutting to stable conditions, reinforced with approved 200-pound reinforcement geotextile and a 12-inch lift of compacted dirty tailings or rock dirt combination (RDC) with a nominal maximum particle size of four (4) inches prior to placing addition fill material. Note that undercutting depths shall not exceed 18 inches and all areas requiring such modifications should be reviewed and approved by the GER (or his representative). Where portable compaction equipment is used, such as utility trenches, the loose lift thickness should not exceed 6 inches to achieve the required degree of compaction without delay. The site contractor should be mindful of the moisture sensitivity and surface shearing characteristics of the site soils and expect that earthwork and open at -grade subgrade preparation could be more problematic than typical. Where construction traffic or weather has disturbed the subgrade, the upper 8 inches of soils intended for structural support should be scarified and re -compacted. Box culverts, drainage structures, and pipes shall be installed according to section 302 of the current Road and Bridge Specifications. All trench work shall be performed in accordance with current OSHA Safety Regulations. Storm water management shall be installed in accordance with VDOT standard drawing PB-1 which is included in the appendix. Bedding material for culvert foundations, shall be VDOT 2 1 A conforming to the requirements of Section 205 of the 2016 VDOT Road and Bridge Specifications. Class I backfill material shall be aggregate base material size VDOT 2 1 A or flowable fill. Regular backfill material outside the neat lines of the Class I areas shown on the Standard GEOTECHNICAL • GEOPHYSICAL CONSTRUCTION • MATERIALS AA Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 Page 9 VE VIOLA ENGINEERING, PC: PB-1 drawings shall be regular excavation. Rock more than 2 inches in its greatest dimension shall not be placed within 12 inches of pipe. Although site conditions are very favorable for this project, we cannot stress enough the importance of adequate project oversight. All fill operations and subgrade preparation should be observed on a full-time basis, in accordance with Chapter 17 of the Virginia Construction Code and/or VDOT requirements, by an authorized representative of the Geotechnical Engineer to determine that compaction requirements are being met. A statement of compliance shall be prepared by a professional engineer, licensed in the state of Virginia, indicating that all fill placed meets the requirements of applicable standards, the Virginia Construction Code, and this geotechnical report. We highly recommend that Viola Engineering, PC be contracted to provide construction monitoring services for site grading to adequately enforce and/or confirm geotechnical requirements are achieved. The limits of proposed building and pavement areas should be field staked prior to fill placement. Grade control should be maintained throughout earthwork operations. Compaction testing shall not be limited; however, adequate testing shall be performed during construction to ensure density requirements are achieved within tolerable moisture content. Compaction tests shall be conducted utilizing a properly calibrated nuclear density gauge or sand cone apparatus. The elevation and location of tests should be clearly recorded. It is emphasized that continuous monitoring and documentation of engineered fill is necessary to determine if compaction was achieved according to the project specifications. Field density testing is employed to verify compaction numerically relative to the maximum dry density and optimum moisture as determined by specified ASTM/VTM procedures. STORMWATER MANAGEMENT FACILITIES Special considerations should be made for the construction of stormwater management (SWM) ponds for this project. We recommend that the pipe culverts under or through the dams should be concrete pipe with rubber gaskets. Installation of a concrete cradle in accordance with standard drawing SWM-DR of the 2008 VDOT Road & Bridge Standards is a preferred anti -seep method. The concrete cradle should extend from the riser or inlet end of the pipe to the outlet of the pipe. We recommend that precast concrete structures be installed according to latest revisions of the VDOT Road and Bridge Specifications. The excavated material is limited as embankment material (USCS Classification: GM/SM) without amending to restrict seepage. GEOTECHNICAL • GEOPHYSICAL CONSTRUCTION • MATERIALS AA Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 Page 10 VE VIOLA ENCINEERINC, PC Stormwater pond embankments and liners shall be designed and constructed according Virginia Department of Environmental Quality 2013 Virginia Stormwater Management Handbook. FOUNDATIONS We expect that bridge foundations will bear on undisturbed weathered bedrock of uniform support characteristics. Based on planned site grading, retaining walls will bear predominantly in residual site soils of reduced support strength. As such, retaining wall foundation systems shall be designed with an allowable bearing capacity of 2500 psf in accordance with VDOT specifications and shall bear a minimum of 24 inches below finish subgrade. Final structural plans and loading conditions have not been furnished to our office, at the time of this writing. We request an opportunity to review final structuralplans to verify our design requirements are met All foundation excavations for structures, pipe, and box culverts shall be excavated in accordance with the latest revisions of section 401 of 2016 VDOT Road and Bridge Specifications. Based on soil strength characteristics, we recommend that bridge foundations be designed with an allowable bearing pressure of 5,000 psf. Foundation design utilizing shallow continuous footings are recommended for the proposed bridges and is the most economical design alternative. Bridge abutment and wing wall foundations shall bear a minimum of 30 inches below existing grade to provide adequate frost protection. Foundation bearing elevation shall be undercut 30 inches or to a depth to expose competent weathered bedrock with SPT values greater than 40 blows per foot, whichever is greater. Foundation excavations shall be backfilled with VDOT A3 concrete to design bearing elevations. This will protect the bearing elevation from the loss of shear strength due to wetting and promote ease of construction. Ephemeral stream water may infiltrate excavations depending on the time of construction. As such, provisions shall be made to ensure the excavation is maintained in a dry state until concrete backfill is placed. Scour analysis shall be conducted by the design engineer of record, if required, to ensure Virginia DOT and AASHTO LRFD design requirements are met. Foundation bearing depths may need to be increased and/or stream armoring may need to be conducted to satisfy these requirements. Continuous foundations shall be designed with a minimum width of 2 feet to prevent localized shear failure. Incorporating these foundation parameters for this project and good construction practices, settlement will be less than 1 inch with differential settlement no greater than 0.5 inches based on abutment wall loads not exceeding an assumed GEOTECHNICAL • GEOPHYSICAL CONSTRUCTION • MATERIALS AA Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 Page 11 IV) loading of 15,000 plf. We request the opportunity to review and confirm our settlement analysis and recommendations after structural details are finalized. Box culverts shall be installed according to section 302 of the current Road and Bridge Specifications. The Contractor shall explore the foundation below the bottom of the excavation to determine the type and condition of the foundation. Foundation exploration shall extend to a depth equal to 1/2 inch per foot of fill height or 8 inches, whichever is greater. The Contractor shall report the findings of the foundation exploration to the Engineer for acceptance prior to placing pipe. Foundation bearing conditions shall consist of undisturbed stiff soil conditions or approved fill. Streams shall be diverted to prevent water from entering the work area. The exposed box culvert bearing surfaces shall be compacted with a large vibratory smooth drum roller to provide a uniform bearing surface. The subgrade shall be compacted to 95% MDD (VTM-1) as tested accordance with VTM-10. Where the Engineer determines unsuitable foundation material is encountered at the established grade, the Contractor shall remove and replace such material. Backfill for areas where unsuitable material has been removed shall be placed and compacted in accordance with Section 303.04(g) of the specifications. Good site management practices shall be employed to prevent water from entering foundation trenches at all times. Furthermore, foundation trenches shall not be opened unless concrete can be placed immediately thereafter to prevent the possibility of precipitation from entering and softening the exposed bearing elevation. Upon completion of the foundation and stem wall construction, we recommend that all foundation trenches be backfilled with clean compacted soil in accordance with Code requirements and good site management practices. The finished subgrade should be graded to promote positive drainage accordingly. SEISMIC CLASS We have estimated the soil profile type for seismic design based on the strata types encountered. It is our opinion that the site is classified as Site Class C based on the site class determination in the Seventh Edition (2014) AASHTO LRFD Bridge Design Specifications section 3.10.3.1 and according to the generalized soil profile on the site.

A nonwoven geotextile shall be placed between the interface of all open graded stone and fine-grained soils (to include shale/phyllite fills) to prevent the migration of fines. Heavy compaction equipment (large wedge foot rollers) should not be used within a 2:1 distance from the toe of the wall to prevent damage to the wall system. The coefficient of friction between concrete and soil was obtained from the 2014 AASHTO LRFD Bridge Specification Table 3.11.5.3-1. GEOTECHNICAL • GEOPHYSICAL CONSTRUCTION • MATERIALS AA Geotechnical Investigation — Rivanna Village - Phase 2 Albemarle County, Virginia July 25, 2018 VE Page 13 VIOLA ENCANEERiNc, Pc ROADWAYS AND PARKING PAVEMENT RECOMMENDATIONS Pavement sections have been provided as illustrated on sheet 6 of the approved site plans (issued 4/29/18). CBR testing conducted during phase-1 construction on similar subgrade materials yielded a minimum and maximum value of 6.7 and 37.2 (median 11.7). A pavement design analysis was conducted by our office in accordance with the 2014 Pavement Design Guide for Subdivision and Secondary Roads in Virginia (VDOT). Two representative pavement sections were selected which represent the worst -case traffic loading for new subdivision streets. Turning lane pavement design for Richmond Road is outside the scope of this report. A minimum laboratory CBR of 8 is required to satisfy thickness index requirements as computed by the conventional pavement design method (See appendix for design details). As such, the provided pavement sections meet typical guidelines to support the reported traffic counts. The pavement designs are predicated on site grading to promote positive drainage away from road beds to prevent saturation of the supporting soils. CBR testing shall be conducted, prior to the placement of basestone, to ensure design requirements are met. Soil sample frequency and CBR testing for new subdivision streets shall be conducted according to the 2014 Pavement Design Guide for Subdivision and Secondary Roads in Virginia which states: 1.) For streets less than 200 feet in length, one soil sample for conducting AASHTO (AASHTO M 145) and Unified (ASTM D 2488) soil classifications and CBR test is required. 2.) For streets 200 to 500 feet in length, at least two soil samples for conducting AASHTO and Unified soil classifications and CBR tests is required, which includes one at each intersection with an existing state road. 3.) For longer streets, one soil sample shall be taken at each intersection with an existing state road plus one test sample every 500 feet in length, or portion thereof, is required for conducting AASHTO and Unified soil classifications and CBR tests.

The designer should take into consideration ACI requirements/recommendations for slab temperature steel and joint spacing. The finished subgrade of all prepared roadways and parking areas shall be compacted to a minimum of 100% of the maximum dry density as determined by ASTM D698 or VTM 1 within f3% of the optimum moisture and approved by the Geotechnical Engineer of Record prior to placing subbase. Work in this project shall conform to the latest edition of the Virginia DOT Road and Bridge Specifications. We recommend that refuse dumpsters be situated on a concrete pad adequately designed to withstand loads associated with tipping. A minimum pad design should include a 6-inch concrete pad with a 6 x 6-inch 10/10 WWF placed at mid -depth, in addition to turned down edges.
