==Finishing grades and surface layer installation==

This construction stage differs between LID practice types. 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 has guidance for 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. For vegetated LIDs, see the finishing grades and surface layer installation: vegetated LIDs page for stage
