Stockpiling topsoil can damage the structure of the soil. This affects infiltration rate, microbiology and chemistry. The effects can be mitigated by [[Amended topsoil| amendment]] and care in its reuse. Soil compaction by heavy construction machinery is common on many development sites. This significantly reduces the infiltration capacity of the soils and must be minimized.<ref>http://trieca.com/wp-content/uploads/2016/07/Soil-Mgmt-Guideline-Mar-28-2012.pdf</ref>

In some instances, the bulk density of construction compacted soils is similar to values for impermeable surfaces.
