Underground LID features can be built early in the construction process, provided they are protected by a barrier such as a plug. Graphic shows an exfiltration system with a temporary plug keeping construction runoff out of the exfiltration area.

Screenshot 2025-11-12 115000.png|Keep LID installations offline via flow diversion until construction is complete, the drainage area is stabilized, and vehicle mud tracking is stopped. Image shows a [[bioretention]] feature during construction (left) and post-construction (right). The LID feature is protected using geotextile fabric, a sacrificial layer of stabilized sand/growing media with vegetation, and a filter sock. Once surrounding construction is complete, the layer of growing media is removed and the BMP starts receiving flow.

Graphic shows a bioretention feature during construction (left) and post-construction (right). At least 75 cm of native soil is retained between the base of the detention basin and the base of the LID feature, so that sediment accumulation in the detention basin can be removed. Once it is excavated and filled, ESC measures should be put in place to protect it until all drainage area construction and stabilization are complete.
