[[File:construction process.jpg|400px|thumb|right|The five-step construction process for sub-surface and ground-level LIDs.]]
The [[construction]] guidance in this section applies to all sub-surface and ground-level LID practices with a vegetated surface layer. By definition this includes [[bioswale|bioswales]], [[rain garden|rain gardens]], [[bioretention|bioretention gardens]], and [[enhanced swale|enhanced swales]]. Depending on the design, the surface layer of [[exfiltration trenches]] and infiltration [[infiltration chambers|chambers]], [[infiltration trench|trenches]], and [[soakaways]] may also be vegetated.
