==Sub-surface components==

Most LID practices use a combination of sub-surface features such as gravel storage reservoirs, liners, underdrains, monitoring wells, and other components to meet their design objectives. The construction process for sub-surface components works from the ground up. While some LID practices include all the sub-surface components listed below, most designs will not include one or more of these layers or components. [[Permeable pavements]] can have different construction requirements at this stage, mostly regarding compaction of sub-surface layers. '''Installing [[infiltration chambers]] also requires guidance specific to that LID type.'''
