This construction stage differs between LID practice type. The finishing grades and surface layer installation page has guidance for vegetated LIDs and non-vegetated LIDs (i.e., permeable pavements). 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.
