The Dunbridge series consists of moderately deep, well drained soils formed in sandy and loamy drift overlying limestone or dolostone bedrock. These soils are on reefs on lake plains.
Permeability is moderately rapid.
Slope ranges from 0 to 6 percent. 41 degrees 21 minutes 58 seconds N., and long. 83 degrees 18 minutes 58 seconds W., NAD 27. Solum thickness, depth to the base of the argillic horizon, and depth to the lithic contact ranges from 20 to 40 inches, but is typically 20 to 30 inches. The clay content of the particle-size control section averages between 18 to 27 percent.
