A <br /> Mel& <br /> 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.
