Design Considerations
Bridge Hydraulics and Scour
No foundations in the inlet
Located within Hurricane Zone
Storm surge still estimated 5 feet +/- over F.G.
Coastal Storm Surge Modeling (SWAN)
Coastal Wave Action Modeling (ADCIRC)
100-YR and 500-YR Return Intervals Considered
30 ft and 35 ft scour depths estimated in RFP• Attempted to minimize risk to Proposers
