Topsoil

In Plain English

The rich, dark top layer of soil that is stripped and saved during construction, then spread back to support grass and plantings.

Definition

The uppermost layer of native soil, typically 4 to 12 inches deep, that contains the highest concentration of organic matter and biological activity, making it the most fertile layer for plant growth. Topsoil is typically stripped and stockpiled during site clearing and earthwork, then respread over disturbed areas for final landscaping. Topsoil placement depth and quality affect revegetation success.

Example

Six inches of imported topsoil was specified for all disturbed areas to ensure adequate depth for the specified seed mix establishment.
