*In [[swales]] convey flowing water a freeboard of 300 mm is generally accepted as a good starting point.
*In [[bioretention]] the freeboard is being defined as the depth between the invert of the [[overflow]] and the the [[inlet]] 150 mm would suffice, so long as the inlet will not become inundated during design storm conditions.
*In above grade [[stormwater planters]] above grade, the equivalent dimension would be the depth between the invert of the overflow and the lip of the planter (150 mm minimum)
*Where the stormwater planter is configured more like a lined/non-infiltrating bioretention system, the inlet will be the depth to which this is measured, as above (150 mm minimum).
