The Google-based map form the Bergen County Record documents damage to homes throughout the Garden State:

The most severe damage was sustained along the central New Jersey coastline, and in the North Jersey towns of Moonachie and Little Ferry, where massive flooding inundated thousands of homes.

Inland towns were hit by severe winds, knocking out power lines and downing many trees, some landing directly onto adjacent homes.
