  1. Chapter 19 Urban Soils Soil Science and Management, 4E

  2. Objectives • List characteristics of many urban soils • Describe ways of dealing with urban soils • Describe modified and structural soils • Describe erosion control on urban sites • Discuss zero-runoff concepts Soil Science and Management, 4E

  3. Terms to Know • Bioswales • Bioremediation • Brown fields • Debris basins • Hydroseeding • Retention ponds • Recharge basins • Rip-rap • Silt fences Soil Science and Management, 4E

  4. Characteristics of Urban Soils • Soil variability and classification • Buried debris • Compaction • Soil contamination • Deicing salts • Heavy-metal contamination • Brown fields Soil Science and Management, 4E

  5. Urban Erosion • Controlling erosion • Keeping disturbed areas small • Protect disturbed areas • Keep runoff velocities low • Divert runoff away from disturbed areas • Retain sediment on-site • Establishing vegetation • Calculating soil loss Soil Science and Management, 4E

  6. Summary • Urban soils exhibit: • Great variation • Poor soil • Buried debris • Compaction • Contamination • Difficult to classify • Modified and structured soils can improve growth of trees and plants • Keep disturbed areas small • Establish vegetative cover • Divert runoff Soil Science and Management, 4E
