*In [[swales]] conveying flowing water a freeboard of 300 mm is generally accepted as a good starting point.  

*In [[swales]] conveying flowing water a freeboard of 300 mm is generally accepted as a good starting point.  

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

*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 depth between the invert of the overflow and the lip of the planter (150 mm minimum)
