The surficial geology shows that the highlands in the eastern portion of Sherburne County were <br />not completely covered by ice from the Grantsburg sub -lobe. When the Grantsburg sub -lobe was <br />in retreat across the county, outwash was deposited from the melting glaciers. Sand and gravel is <br />located at the surface in some places. Topographic relief comes from the Superior lobe deposits <br />consisting of silty sand to cobble gravel with no shale deposited by meltwater under the ice. <br />There are no sinkholes, shallow limestone formation or karst conditions that exist within the <br />project site. <br />b. Soils and topography - Describe the soils on the site, giving NRCS (SCS) classifications and <br />descriptions, including limitations of soils. Describe topography, any special site conditions <br />relating to erosion potential, soil stability or other soils limitations, such as steep slopes, <br />highly permeable soils. Provide estimated volume and acreage of soil excavation and/or <br />grading. Discuss impacts from project activities (distinguish between construction and <br />operational activities) related to soils and topography. Identify measures during and after <br />project construction to address soil limitations including stabilization, soil corrections or <br />other measures. Erosion/sedimentation control related to storm water runoff should be <br />addressed in response to Item II.b.ii. <br />Soils present on the project site are described below. The Natural Resources Conservation <br />Service (MRCS) Web Soil Survey website was used to identify soils found on the property and to <br />describe the soils. See Figures 10, Appendix A for soil map and Figure 11, Appendix A for <br />topography map. <br />Zimmerman fine sand (15813) 1-6%, slope, can be found on rises. Rises are a land feature <br />consisting of back slopes, shoulders, and summits, and are considered somewhat excessively <br />drained. This excessive drainage causes the water table to be located more than 80 inches in <br />depth. The profile of Zimmerman fine sand goes from fine sand to loamy fine sand. Parent <br />material consists of sandy glacial fluvial deposits. This soil classification is not considered prime <br />farmland. <br />Isan Sandy loam (261), 0-1% slope, is found in depressions, on stream terraces, and outwash <br />plains. This soil is considered very poorly drained. The depth of the water table is at the surface <br />due to the low permeability of the soil. The soil profile consists of sandy loam, loamy sand, and <br />coarse sand. Parent material is outwash from glaciation. This soil is not considered prime <br />farmland. <br />Seelyeville muck (540), 0-1% slope, is found in depressions, on moraines, steam terraces, and <br />outwash plains. This soil is very poorly drained. The poor drainage causes the water table to be <br />at the surface. The soil profile is listed as muck. The parent material consists of organic matter <br />and it is not classified as prime farmland. <br />Markey muck (543), 0-1 % slope is occasionally ponded. Found mainly on depressions it is <br />considered very poorly drained. The depth to the water table is at the surface due to the low <br />permeability. The soil profile consists of muck and sand. The parent material is organic material <br />over outwash. It is not considered prime farmland. <br />Isanti loamy fine sand (1109), 0-2% slope is found on swales on outwash plains. The depth of the <br />water table is about 6 inches, and the soil is considered poorly drained. The soil profile ranges <br />Page 9 <br />
