A summary of our results and recommendations is <br /> presented below. More detailed information and recommendations follow in the report. <br /> Summary of Results <br /> Eight soil borings were completed for this evaluation. Three borings were completed within a proposed <br /> borrow source area and five borings were completed along the fairway for the 15th hole. <br /> The borrow source borings(ST-1, ST-2, and ST-3) encountered about 3 inches of grass and topsoil <br /> underlain by a variety of alluvial soils consisting of poorly graded sand with silt, silty sand, sandy silt, and <br /> clayey silt. <br /> The fairway borings (ST-4 through ST-8) encountered about 6 inches of grass and topsoil overlying varying <br /> depths of peat. Beneath the peat,the borings encountered native silty sand alluvium. The peat ranged <br /> from about 4 feet in boring ST-4 to about 24 feet in boring ST-6. <br /> Summary of Recommendations <br /> We understand the fairway for the 15th hole is difficult to play due to the soft,variable ground conditions <br /> and the Wayzata Country Club desires to provide a more stable fairway. Wayzata Country Club may <br /> borrow soils from the "hill" near the 15th hole and use them to improve the fairway. The soils—primarily <br /> silty sands-identified in the borrow source borings are judged to be suitable for use as general fill to raise <br /> site grades and provide a more stable fairway environment. However, those sands classified as either SP <br /> or SP-SM would provide more rapid drainage than the silty sand soils. <br /> • N <br /> Much of the fairway is underlain by peat,which was found to depths of 4 feet to 24 feet below existing <br /> grades. The peat is a highly organic material and highly compressible. It will settle (consolidate) when <br /> r new fill or additional fill is placed on it. Initial settlement of the peat will depend upon the depth of new <br /> fill placed. Also,the peat will continue to settle over time.
