FEMA Surge Data For Upper Manhattan Marble Hill Area

  In the map below, I brought in FEMA Sea Surge data with my subway and railroad shape files.  Surprisingly, there is less area for concern than I thought would be the case.  Notice the loop shaped area of concern in orange-yellow right at the northern tip of Manhattan.  This was the original path of the Harlem River before it was diverted. This is just an experiment and please do not make any decisions based on this map.
Notice that only one surge height was generated by the map which is not the case in other locations around the city; particularly near the open ocean where many ranges are displayed.
