- I would like to know why porter had to be set so deep...
-
- Because of loading and clearance considerations of the tracks and also
- because it is descending to go under built up areas to get to Davis.
- There were some serious considerations in the Porter-Davis segment
- about not disturbing any of the existing buildings, their foundations,
- or other things. John Hancock Insurance had just lost a BIG lawsuit
- by the church next door to their new building, on the grounds that the
- construction had depeleted the water table and that had caused
- settling which required extremely expensive restoration to a
- historical structure. The T didn't want to end up with the same kinds
- of problems... I think this is also the reason why they're at
- different levels at Porter. The two tunnels follow slightly different
- routes under the parking lot and shopping area and one needed more
- clearance than the other.
