4 GEOTECHNICAL ENGINEERING REPORT DOWNTOWN GREENVILLE FUTURE CONVEYANCE STUDY GREENVILLE, SOUTH CAROLINA Terracon Project No December 1, INTRODUCTION A geotechnical engineering report has been completed for the proposed Downtown Greenville Future Conveyance Study in. Eight (8) SPT borings and fifteen (15) rock probes were performed to depths of approximately 9 ½ to 90 feet below the existing ground surface along the proposed sewer line route. Logs of the borings, a vicinity map and boring location plans are included in Appendix A of this report. The purpose of these services is to provide information and geotechnical engineering recommendations relative to: subsurface soil conditions groundwater conditions earthwork depth to rock or Partially Weathered Bedrock 2.0 PROJECT INFORMATION 2.1 Site Location Site Location ITEM Location Existing improvements Current ground cover Existing topography DESCRIPTION The proposed sewer line will start south of E. Washington Street (Greenville Zoo parking) and will terminate near the intersection of Stone Plaza Drive and Chick Spring Road in. Existing ReWa sewer lines are installed in the vicinity of proposed line. Route has various structures and utilities. Grass, small brush and pavement etc. Based on the Greenville County GIS system contour maps, in general the site elevation at the proposed sewer is sloping down towards the east direction Responsive Resourceful Reliable 1

5 Geotechnical Data Report Downtown Greenville Future Conveyance Study December 1, 2015 Terracon Project No Project Description ITEM Proposed Study DESCRIPTION ReWa is evaluating the existing sewer lines through downtown. There are four (4) possible solutions and each needs geotechnical investigation. There are two storage options upstream of downtown, one microtunneling/ open cut route and one option of a tunnel 100 vertical feet below downtown. Should any of the above information or assumptions be inconsistent with the planned construction, please let us know so that we may make any necessary modifications to this proposal. 3.0 SUBSURFACE CONDITIONS 3.1 Geology The project site is located within the Piedmont Physiographic Province of South Carolina, an area underlain by ancient igneous and metamorphic rocks. The topography and relief of the Piedmont has developed from differential weathering of the igneous and metamorphic bedrock. The residual soils in this area are the product of in-place chemical weathering of rock. The typical residual soil profile consists of clayey soils near the surface where soil weathering is more advanced, underlain by sandy silts and silty sands that generally become harder with depth to the top of parent bedrock. The boundary between soil and rock is not sharply defined due to variations in weathering and the presence of soft rock. The transition zone is locally termed as partially weathered rock. Partially weathered rock is defined for engineering purposes as residual material that can be drilled with soil boring methods, but exhibits standard penetration test (SPT) N- values exceeding 100 blows per foot (bpf). The depth to partially weathered rock occurs at irregular depths due to variations in degree of weathering and variations in the material composition of the rock. Responsive Resourceful Reliable 2

The boreholes were backfilled at the termination of exploration, making subsequent water level readings unobtainable. Due to the low permeability of the soils encountered in the borings, a relatively long time may be necessary for a groundwater level to develop and stabilize in a borehole in these materials.

8 Geotechnical Data Report Downtown Greenville Future Conveyance Study December 1, 2015 Terracon Project No piezometers or observation wells sealed from the influence of surface water are often required to define groundwater levels in materials of this type. Groundwater level fluctuations occur due to seasonal variations in the amount of rainfall, runoff and other factors not evident at the time the borings were performed. In addition, perched water could develop in sand seams and layers overlying lower permeability clay soils following periods of heavy or prolonged precipitation. Therefore, groundwater levels during construction or at other times in the life of the structure may be higher or lower than the levels indicated on the boring logs. The possibility of groundwater level fluctuations should be considered when developing the design and construction plans for the project. 4.0 GENERAL COMMENTS Terracon should be retained to provide testing and observation during excavation and other construction phases of the project. The analysis and recommendations presented in this report are based upon the data obtained from the borings performed at the indicated location and from other information discussed in this report. This report does not reflect variations that may occur across the site, or due to the modifying effects of weather. The nature and extent of such variations may not become evident until during or after construction. If variations appear, we should be immediately notified so that further evaluation and supplemental recommendations can be provided. The scope of services for this project does not include either specifically or by implication any environmental or biological (e.g., mold, fungi, bacteria) assessment of the site or identification or prevention of pollutants, hazardous materials or conditions. If the owner is concerned about the potential for such contamination or pollution, other studies should be undertaken. This report has been prepared for the exclusive use of our client for specific application to the project discussed and has been prepared in accordance with generally accepted geotechnical engineering practices. No warranties, either express or implied, are intended or made. Site safety, excavation support, and dewatering requirements are the responsibility of others. In the event that changes in the nature, design, or location of the project as outlined in this report are planned, the conclusions and recommendations contained in this report shall not be considered valid unless Terracon reviews the changes and either verifies or modifies the conclusions of this report in writing.

19 Geotechnical Data Report Downtown Greenville Future Conveyance Study December 1, 2015 Terracon Project No Field Exploration Description The boring locations were laid out on the site by Terracon personnel and were measured from available site features. The soil test borings were surveyed and accurate location and elevation survey was performed. The borings were drilled using a track-mounted and a truck-mounted rotary drill rig using continuous flight hollow-stem augers to advance the boreholes. Samples of the soil encountered in the borings were obtained using the split-barrel sampling procedures. In the split-barrel sampling procedure, the number of blows required to advance a standard 2-inch O.D. split-barrel sampler the last 12 inches of the typical total 18-inch penetration by means of a 140-pound conventional safety hammer with a free fall of 30 inches, is the standard penetration resistance value (SPT-N). This value is used to estimate the in-situ relative density of cohesionless soils and consistency of cohesive soils. An automatic SPT hammer was used to advance the split-barrel sampler in the borings performed on this site. A greater efficiency is typically achieved with the automatic hammer compared to the conventional safety hammer operated with a cathead and rope. Published correlations between the SPT values and soil properties are based on the lower efficiency cathead and rope method. This higher efficiency affects the standard penetration resistance blow count (N) value by increasing the penetration per hammer blow over what would be obtained using the cathead and rope method. The effect of the automatic hammer's efficiency has been considered in the interpretation and analysis of the subsurface information for this report. The samples were tagged for identification, sealed to reduce moisture loss, and taken to our laboratory for further visual examination and classification. Information provided on the boring logs attached to this report includes soil descriptions, consistency evaluations, boring depths, sampling intervals, and groundwater conditions. The borings were backfilled with auger cuttings prior to the drill crew leaving the site. A field log of each boring was prepared by the drill crew. These logs included visual classifications of the materials encountered during drilling as well as the driller s interpretation of the subsurface conditions between samples. Final boring logs included with this report represent the engineer's interpretation of the field logs and include modifications based on laboratory observation and tests of the sample. Exhibit A-10

20 Laboratory Testing Description Samples retrieved during the field exploration were taken to the laboratory for further observation by the project geotechnical engineer and were classified in accordance with the Unified Soil Classification System (USCS) described in Appendix C. At that time, the field descriptions were confirmed or modified as necessary and an applicable laboratory testing program was formulated to determine engineering properties of the subsurface materials. Laboratory tests were conducted on selected soil samples and the test results are presented in this appendix. The laboratory test results were used for the geotechnical engineering analyses, and the development of foundation and earthwork recommendations. Laboratory tests were performed in general accordance with the applicable ASTM, local or other accepted standards. Selected soil samples obtained from the site were tested for the following engineering properties: Particle-Size Analysis of Soils ASTM D422 Liquid Limit, Plastic Limit, and Plasticity Index of Soils ASTM D4318 Laboratory Determination of Water (Moisture) Content of Soil ASTM D2216 Unconfined Compression of Bedrock ASTM D7012
