  • any change to a building or structure that would have the effect of altering the use or potential use of the building or structure,
  • increasing the size of a building or structure or increasing the number of dwelling units in the building or structure,
  • site grading
  • the temporary or permanent placing, dumping or removal of any material, originating on the site or elsewhere.
