If you want to see what NYC might experience in this situation, check out what happened to Mobile, AL during Hurricane Ivan.

Storm surge of 10-15 ft occurred along the coasts from Destin in the Florida panhandle westward to Mobile Bay/Baldwin County, Alabama. Storm surge values of 6-9 ft were observed from Destin eastward to St. Marks in the Florida Big Bend region.

Good thing for NYC is that this is a weaker hurricane, but the potential for a larger storm surge is still there, especially if it occurs during high tide. The reason I draw a parallel between NYC and Mobile is because Irene is likely to make landfall east of the city, like Ivan did. Also, Mobile Bay created a funnel, causing storm surge to be exaggerated and concentrated. Something similar to that could occur with y'all.
Also, our tunnels were flooded. The pumps weren't nearly enough to keep them dry.
Downtown was under about 5 or 6 feet of water. The city sits maybe 8 to 10 feet above sea level. Like Mobile, not all of NYC will be flooded, as there are many parts of the city that are high enough to escape the surge.
Good news is that the city of Mobile recovered quickly. Construction on the RSA Battlehouse Tower was halted for an amount of time, but resumed relatively soon.
