The open space dodge: would it be built just over the rail yards?

The section on Open Space in the new Atlantic Yards.com web site promises:
As part of the development, FCRC will transform portions of the exposed rail yards into publicly accessible open space that everyone can enjoy. (Emphasis added)

While portions of the rail yards would indeed become "publicly accessible open space," the phrasing suggests that the open space would be built only above the unsightly rail yards. Rather, if you compare the sketch from FCR's web site (above) with the schematic of the project footprint, it's clear that open space would be built over the currently functioning Pacific Street, as well as the area between Pacific and Dean streets currently occupied by buildings. And, given the controversy over the taking of Pacific Street to create a superblock, it's another deception that shouldn't be ignored.
