<br>Many types of LID practices are designed to retain water within an internal water storage reservoir or layer (e.g. full and partial infiltration [[Bioretention|bioretention], [[Stormwater tree trench|stormwater tree trench]] and [permeable pavements|permeable pavement]] designs, infiltration trenches and chambers, and exfiltration trenches). To facilitate measurement of water level in the internal water storage reservoir or layer and periodically evaluate drainage performance over the operating life cycle of the facility, include a monitoring well located in the lowest elevation portion of the practice or system:

* Include monitoring wells in design drawings and details and install at an appropriate time during construction, or as part of repair work for facilities in need of rehabilitation.

* Ensure the perforated section of the well is located within the internal water storage reservoir or layer only, and that it extends to the bottom elevation of the practice at a minimum.
