4. The study had its beginnings in the mid to late 1990s but it became a formal federal action in December 2002 when the NYSTA and MTA/Metro North, working with the FHWA and FTA,  filed a notice of intent in the federal register.

Since that time a considerable amount of work has been accomplished; in 2003-2004 considerable effort was dedicated to the initial scoping.  Two levels of screening were accomplished, starting with 150 ideas, leading to 6 alternatives.

In 2004 -2005 efforts were focused on the alternatives analysis report which documented the basis for the decisions leading to the six alternatives.
That study was published in January 2006.

Since, then, in 2006-2007, the team has been doing the engineering and environmental research necessary to advance the DEIS.

All of the work done since December 2002 remains a critical component of this study.  All of that work is incorporated into the record moving forward. (4 of 33)
