WTC: What Footprint At What Price?
"At the center of the dispute is the definition of 'footprint,' the term used to describe the two unmarked rectangles where the twin towers stood. Pataki has pledged not to allow development on the footprints, but current plans call for reconstruction of a New Jersey PATH train and other infrastructure six to seven stories below ground down to the so-called bedrock level. Family members have said both footprints, reaching down to the bedrock, should be protected because many bodies were found in rubble deep beneath the surface of the World Trade Center. Plans to build below ground in that area were disclosed only recently."
