Dominant Soils are Urban Land and Oshtemo Sandy Loam.

Urban land (Ub, purple at mouth of watershed) are those areas that are so obscured by urban work and structures that identification of the soil is not possible. Urban land-Kalamazoo Complex, 0 to 6 percent slopes (UkB, pink along eastern side of watershed) are composed of a level and undulating, well drained soil on uplands. Urban land makes up 60 to 70 percent of the map unit and Kalamazoo soil comprise 30 to 40 percent. The urban land and Kalamazoo soils are so mixed that it is not practical to separate them. The Kalamazoo soil is suited to building site development and sanitary facilities. The Oshtemo Sandy Loam (OsB, light blue near the southern end of the watershed) is hilly, well drained soil on sandy uplands and ridges. The use of this soil for hay and pasture is effective in controlling erosion. Slope and erosion are the major problems. The Oshtemo Sandy Loam is poorly suited to building site development. Care must be taken in establishing septic tank filter fields to prevent hillside seepage.

The above explanation was paraphrased from the Soil Survey for Kalamazoo County, USDA SCS, 1979.
