A geotechnical exploration was conducted for the Proposed Dollar General located at US Highway 75 and West Pleasant Avenue in Warren, Minnesota. The investigation involved the advancement of nine soil test borings to depths ranging from approximately 11 to 21 feet below existing site grades. The subsurface profile revealed the presence of uncontrolled fill and organic topsoil extending to depths of 1 to 3 feet, underlain by lean and fat clays, which exhibited varying consistencies from very soft to stiff. Groundwater was not observed during drilling, but it is estimated to be between 10 and 12 feet below the surface, with potential for seepage in open excavations. The fat clays encountered are prone to volumetric changes with moisture fluctuations, necessitating careful management during construction to avoid disturbance.

For the foundation design, shallow spread footings are recommended, with a net allowable bearing pressure of 1,500 psf for columns and 1,200 psf for walls, requiring a minimum embedment of 60 inches for frost protection. It is crucial to excavate and replace the existing fill and topsoil with controlled engineered fill to ensure adequate support. Construction considerations include maintaining moisture content in the subgrade, avoiding disturbance from construction traffic, and implementing proper drainage to prevent water accumulation. Overall, the site is deemed suitable for the proposed development, provided that the outlined recommendations are followed, and Terracon is retained for monitoring during construction activities.
