*In [[bioretention]] the freeboard is the difference between the invert elevation of the [[overflow]] structure and the [[inlet]]. 150 mm will suffice, so long as the inlet will not become inundated during design storm conditions.

*In above grade [[stormwater planters]], the equivalent dimension would be the difference between the invert elevation of the [[overflow]] structure and the lip of the planter (150 mm minimum)
