Some of it is typical, some is not, certain areas will set up as 'erosion zones' in the late 70's areas east of the C-Town Breachway suffered severe erosion (as did most beaches with the bliz of 78)
Currently, a large erosion zone exists in the vacinity of SK Town beach and Carpanters Beach; take a look and you'll see what I mean
East of the Charlestown breach faired well, in part due to the large volume of sand added to the system during the winter/spring dredge-dumping
This was an odd storm; not overly powerful, but the slow to no movement of it coupled with many high tides with a storm surge (20-40cm, not huge by any means but it has an impact) made it pretty erosional in most places, along with the huge long period swells.
Generally the 5 factors that influence coastal erosion are:
Storm intensity
Duration
Tidal Cycle
time between storms
path or storm track
(Hayes and Boothroyd, 1969)
This guy had two of these for SE New England, Duration and tidal cycle (spring tides) and if it had sat west of us, we would have had SE winds and even bigger, shorter period swells...
I sense it's gonna be a long winter for coastal home owners, just a gut feeling...
