context_page_description: Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage. The earthworks created for such a purpose are often called the sub-grade or finished contouring.
context_section_description: Regrading is the process of grading for raising and/or lowering the levels of land. Such a project can also be referred to as a regrade. 
  Regrading may be done on a small scale (as in preparation of a house site) or on quite a large scale (as in major reconfiguration of the terrain of a city, such as the Denny Regrade in Seattle). 
  Regrading is typically performed to make land more level (flatter), in which case it is sometimes called levelling.) Levelling can have the consequence of making other nearby slopes steeper, and potentially unstable or prone to erosion.
