* Freeboards should be adequate to prevent over-topping during storm events and allow overflow of less frequent storm events through controlled and protected emergency overflow points. Berm freeboards should also consider berm soil consolidation and subsidence, and also that the wetland can gradually fill with vegetation and with sediments which increase flow resistance and decrease freeboard during wetland life.

* Controlled overflow points that are riprapped dips in the surface or concrete weirs should be incorporated into the top of the berm of each wetland cell so that if the wetland is overtopped the flow exiting the wetland does not cut channels into the top of the berm that could compromise the integrity of the berm.
