With the inputs finished into HEC-RAS, the minimum height of 12′ above high tide was kept.  The mean sea level is 0′, plus the high tide at 7′.  This puts the low chord of the bridge at 19′.  Even though the current model shows a pile design, the pile design is not complete.  Once a pile design is selected it can be inputted into HEC-RAS and the scour can be ran on the model.
