[StBernard] Corp of Engineers

Two questions:
 
1.  Why is the standard levee height 17.5 feet?  I thought the storm surge
was 30 something  feet high.   If so, what good is a 17.5 foot levee going
to do?
 
2.  If  there is a MRGO flood gate put right near the "Green Bridge",
wouldn't St. Bernard flood every time that flood gate is closed?  Seems like
such a flood gate would protect New Orleans at the expense of St. Bernard
especially the areas below Paris Road.
 
Many thanks,
