==Finishing grades and surface layer installation==
This construction stage differs between LID practice type. The [[finishing grades and surface layer installation: vegetated LIDs]] page has guidance for vegetated LIDs, and the '''finishing grades and surface layer installation: permeable pavements''' page has guidance for and non-vegetated LIDs. In many cases the surface of infiltration systems will be traditional asphalt, concrete, or pavers; STEP does not provide guidance on installing non-permeable surfaces.
