What is that Straight Green Line in Brooklyn?

  I brought up my NYC Polar Cap Melt Scenario shapefile and applied it for Southern Brooklyn.  A very long straight line caught my eye.  The straight line represents an area that is in danger of flooding by 2020 if the polar ice caps should melt.  What do you think that it is? Hint:  _ "as in "Nancy".  This result is the same as an earlier posting using "GRASS 6.4.1" program using the hydrology option for raster files  (Hydrologic Modeling, Carve Stream Channels.) to produce a stream map.
The map below includes a building footprint shapefile and concentrates on the Marlboro Houses area.
