<br /> <br /> <br />Geotechnical Report <br />2018 PMP Streets <br />Arden Hills, Minnesota <br />WSB Project No. 010111-000 Page 1 <br />1. INTRODUCTION <br /> <br /> Project Location <br />The borings were located along the following roadways: <br />Wedgewood Circle <br />Parkshore Drive <br />Brueberry Lane <br />Indian Oaks Court <br />Indian Oaks Trail <br />West Floral Drive <br />Norma Circle <br />Gale Circle <br />James circle <br /> <br />The approximate soil boring locations can be found on the Soil Boring Exhibit in Appendix A. This site is <br />located in T30N, R23W, Section 21 and 22 of Ramsey County. <br /> <br /> Project Description <br />It is proposed to construct new underground utilities including new storm sewer, sanitary sewer, and <br />watermain. We understand the invert elevations for these utilities will be within 13 feet of grade. The <br />roadways will be reconstructed as a bituminous pavement section with concrete curb and gutter. <br /> <br />We understand the vertical and horizontal alignments of the roadway will remain relatively unchanged. <br /> <br />WSB has developed recommendations for this project in consideration of the proposed layout, loadings, <br />and configurations as understood at this time. WSB must be made aware of the revised or additional <br />information in order to evaluate the recommendations for continued applicability. <br /> <br /> Purpose and Project Scope of Services <br />Ms. Polka with the City of Arden Hills (City) authorized this work. In order to assist the design team in <br />preparing plans and specifications, we have developed recommendations for designing the pavement <br />section and for construction of underground utilities. As such, we have completed a subsurface <br />exploration program and prepared a geotechnical report for the referenced site. This stated purpose was <br />a significant factor in determining the scope and level of service provided. Should the purpose of the <br />report change the report immediately ceases to be valid and use of it without WSB’s prior review and <br />written authorization shall be at the user’s sole risk. <br /> <br />Our authorized scope of work has been limited to: <br /> <br />1. Mobilization / Demobilization of a Truck Mounted Drill Rig. <br />2. Clearing underground utilities utilizing the Gopher State One Call. <br />3. Drilling eighteen (18) standard penetration borings to 10 to 25 foot depths. <br />4. Sealing the borings per Minnesota Department of Health procedures. <br />5. Perform soil classification and analysis. <br />6. Review of readily available project information and geologic data. <br />7. Providing this geotechnical report containing: <br />a. Summary of our findings. <br />b. Discussion of subsurface soil and groundwater conditions and how they may affect the <br />proposed pavements. <br />c. Estimated R-value of the soils. <br />d. Recommended pavement section. <br />e. A discussion of soils for use as structural fill and site fill.
