What does the term "grade, natural" refer to?

The term "grade, natural" specifically refers to the original land slope or contour before any modifications have been made, such as excavation or filling. This concept is crucial in site analysis and planning because it provides a baseline understanding of the terrain's natural condition. It helps landscape architects and planners assess how the land will interact with water drainage, vegetation, and the overall ecosystem.

Understanding the natural grade informs decisions about adjustments that may be necessary for construction or landscaping projects, making it an essential aspect of both design and environmental impact assessments. Accurate knowledge of the natural grade can influence design solutions to maintain or enhance the landscape's integrity and functionality.
