CL This report presents the methods, data and results of a subsoil investigation performed for the New Water Plant Intake Line to be constructed through Indian Rock Park in Salina, Saline County, Kansas. The work was authorized by Mr. Don Hoff on January 25, 1988. The scope of the subsoil investigation included test borings, geophysical surveys and a report of recommendations concerning the design and excavation for the proposed New Water Plant Intake Line. The purpose of this study was to evaluate the extent, composition and engineering properties of the site soils. Data from this study was used to estimate whether or not there would be significant difficulties with excavation the proposed intake pumping station or the water line for the proposed New Water Plant Intake Line. This investigation was made by Geotechnical Services, Inc. with the report written by a professional geotechnical engineer registered in the State of Kansas. 11lw:1%.L9(:T91*(a1l It is proposed to construct a new intake line for the Salina water plant. This will involve putting a new intake and pump station in the Smoky Hill River bank near the upstream end of the diversion channel. 'A new intake line would then run from this station to the water plant. This new line would run through Indian Rock Park which sits on bedrock. For hydraulic reasons, it is planned to have this line run as deep as 18 feet (5.5 meters, m) below the surface. G E O T E C H N I C A L S E R V I C E S I N C The field investigative and exploratory program for this site was conducted on February 3 and 4, 1988. The exploratory program consisted of 5 test borings located as shown on the Boring Location Plan (Appendix A). Test borings were roughly located in plan visually with reference to an airphoto of the site (ro scale) furnished by Wilson & Company Engineers & Architects. The location and elevation of 3 of the test borings was subsequently surveyed in by Wilson & Company. Test borings were advanced to depths of 10 to 50 feet (3.0 to 15.2 m) below existing grade with a truck mounted Mobile B-50 motorized drill rig. Borings were advanced and cleaned out using 4.0 inch (102 millimeters, mm) diameter continuous flight augers. Since borings remained open during drilling operations, casing or other stabilization measures were not required. No samples were taken. The drilling data was supplemented by means of 4 seismic surveys conducted along the route of the intake line. This data provided information on the depth to bedrock and provides an excellent estimate of whether or not the rock can be ripped based on the velocity of sound waves in the rock. SITE CDNDITIDNS At the entrance to the diversion channel, the bottom of the Smoky Hill River is at approximate elevation 1,208. The top of the bank of the diversion channel at this point is at approximate elevation 1247. Along the proposed route of the intake line, the elevation rises to a peak elevation of about 1264. The intake line levels off at an elevation of about 1246, so the line is about 18 feet below the surface at this point. Farther to the west, the elevation along the route of the intake line drops until it is below elevation 1230 when it reaches Indiana Avenue. This subsoil investigation indicated that the subsoils consist of residual soils overlying the Wellington Formation. The residual soils are described as dark brown to light reddish brown, dry to moist, soft to medium stiff, sandy clay to clay. In the test borings, the residual soils extended to depths of 9 to 12 feet (2.7 to 3.7 m). In two of the test borings, the residual soils extended to below the depth drilled. The Wellington Formation was described as a light brown to grayish brown to dark gray, dry to moist, firm to stiff, shale. A few hard limestone seams were encountered, but the thickest of these was only 3 inches (8 centimeters, cm) thick. A generalized profile showing the approximate surface of the Wellington Formation relative to the surface is shown on the Pipeline Profile (Appendix B). The surface elevations of this profile are based on a preliminary profile provided by Wilson & Company as further defined by a subsequent survey. A more detailed description of the soils encountered is shown on the Boring Logs 2 G E O T C(Appendix C). The surface of the shale may vary from that shown as the test H holes and seismic surveys were not run directly over the pipeline route. H I Additionally, the surface boundary between boreholes is not exactly known C between boreholes. Finally, the transition between the residual soils and the A shale bedrock is a gradual transition. L S GROUND WATER E R Water level readings were made in the drill holes at times and under the V conditions stated on the Boring Logs (Appendix C). It appears that the ground I water level is at this time below the depths explored. However, it must be C noted that fluctuations in the level of the ground water may occur due to E S variations in rainfall, temperature, and other factors at the time measurements are made. I H CONCLUSIONS AND RECOMMENDATIONS C The results of the seismic surveys indicate a two -layer case with soil and residual shale occurring over a predominantly shale bedrock with some thin limestone seams. Velocities in the surface layer ranged from 727 to 1311 feet per second (222 to 400 meters per second, m/s). These velocities are consistent with anticipated overburden velocities and are very rippable. Fortunately frost was not a significant factor in most of the surveys. The frost layer was not thick enough to cause data collection interference. The second layer encountered (shale as determined by the test borings) had velocities ranging from 6,100 to 8,571 feet per second (1959 to 2612 m/s). These values are consistent with clayey shales. There should be no problem ripping this material. The seismic data indicates that some of the bedrock under survey S-4, near the west end of the area investigated, may not be rippable. Fortunately, this material is well below the depth to which the excavation will be dug in this area. The profile of the pipeline (Appendix B) shows the boundary between soil and bedrock over the area studied along the proposed intake line route. Combining the borehole data and the seismic data, we have 11 depth to bedrock data points. It appears that the excavation will extend into the bedrock at three places. These are at the pump station, at the top of the hill, and at the site of test boring DH -5. In the event that any changes in the nature, design, or location of the project are planned, the conclusions and recommendations contained in this report shall not be considered valid unless the changes are reviewed and the conclusions of this report modified or verified in writing by Geotechnical Services, Inc. It is recommended that Geotechnical Services, Inc. be provided the opportunity for a general review of the final design and specifications in order that earthwork and foundation recommendations may be properly interpreted and implemented in the design and specifications. 3
