   (f)   Infiltration means the process of percolating storm water into the subsoil.
   (g)   Land disturbance activity means any activity that changes the volume or peak flow discharge rate of rainfall runoff from the land surface.  This may include the grading, digging, cutting, scraping, or excavating of soil, placement of fill materials, paving, construction, substantial removal of vegetation, or any activity which bares soil or rock or involves the diversion or piping of any natural or man-made watercourse.
