What operation involves uprooting and removing roots and stumps from the ground?

Grubbing operations specifically refer to the process of uprooting and removing roots and stumps from the ground. This is a crucial step in land clearing and preparation for construction or landscaping projects. During grubbing, not only are visible stumps and roots taken out, but the operation also often involves the process of removing other organic material to ensure the ground is adequately prepared for further development or landscaping.

In contrast, stripping operations typically deal with the removal of topsoil and vegetation rather than the deeper roots and stumps. Clearing operations usually encompass a broader activity focused on removing all types of vegetation, including trees and shrubs, but does not specifically highlight the removal of roots and stumps as its primary goal. Lastly, drainage operations pertain to managing water flow and improving land drainage, which is a different focus entirely from the physical removal of tree roots and stumps. Thus, grubbing operations are defined clearly by their specific goal of dealing with underground elements, making it the appropriate choice.
