August 6, 2021 HGTS Project Number: 21-0561 <br />Ms. Tracey Rust <br />The Excelsior Group <br />1660 Highway 100 South, Suite 400 <br />St. Louis Park, MN 55416 <br />Re: Geotechnical Exploration Report, Proposed Trott Brook Property, Residential <br />Development, West of Nowthen Boulevard NW and North of Trott Brook, Ramsey, <br />Minnesota <br />Dear Ms. Rust: <br />We have completed the geotechnical exploration report for the proposed residential <br />development in Ramsey, Minnesota. A brief summary of our results and recommendations is <br />presented below. Specific details regarding our procedures, results and recommendations <br />follow in the attached geotechnical exploration report. <br />Twelve (12) soil borings were completed for this project that encountered about 1f oot of sandy <br />topsoil that was underlain by predominantly sand soils that extended to the termination <br />depths of the borings. Groundwater was encountered in the soil borings at depths ranging <br />from about 7 1/2 to 19 1/2 feet below the ground surface and to further evaluate groundwater <br />levels three piezometers were installed. Water level measurements are on -going and results <br />will be forwarded as they become available. <br />The vegetation and topsoil are not suitable for foundation support and will need to be <br />removed from within the proposed building and oversize areas and replaced with suitable <br />compacted engineered fill. In our opinion, the underlying native alluvial soils are generally <br />suitable for foundation support. However, the native sands had a loose relative density and <br />will need to be surface compacted to increase their density to provide adequate foundation <br />support. <br />With the building pad prepared as recommended it is our opinion that the foundation for the <br />proposed building can be designed for a net allowable soil bearing capacity up to 2,000 pounds <br />per square foot. <br />Thank you for the opportunity to assist you on this project.
