MassDOT Green Line Extension March status report

17 March, 2013 (22:24) | Documents, News | By: Editor

MassDOT has posted the March status report on the Green Line Extension project. Below are highlights of new information since the February report:

Design Progress
The designs of Ball Square and Gilman Square Stations have proceeded, taking into consideration the design study at Ball Square, the City of Somerville’s “Somervision” process, and the ideas accepted from the Value Engineering study. Overall, the size of the stations has been reduced by about 10 percent.

In order to reach resolution of egress issues, the MBTA submitted a variance request to gain acceptance of the Advanced Conceptual Design of the emergency egress from the end of four station platforms (College Avenue, Ball Square, Lowell Street and Union Square). In early March, these variance requests were all granted, allowing for design to proceed on the emergency egress elements off the end of these station platforms.

The project team has continued to meet and coordinate design issues with representatives from the three communities including: (1) A meeting with the City of Somerville and Friends of the Community Path on the path connections in the Red Bridge area and met with the City of Cambridge on interim parking near Lechmere Station; (2) A meeting with the City of Medford on the revised Ball Square plans; (3) Meetings with the City of Somerville and the City of Medford on the Phase 1 Construction Plan, a local abutters meeting for the work around the Harvard Street bridge location as well as one with the general public in regard to the Phase 1 work.

As a follow-up to the January 2013 Coordination meeting with the Mass Historic Commission on the details of the viaduct demolition, a Historical American Engineering Report (HAER) is being prepared for submittal in March 2013.

Real Estate
The GLX Relocation Plan has been submitted to the FTA for comment. Additional schedules to implement the real estate acquisition process in a prioritized manor are being developed in conjunction with the MBTA’s Real Estate department and then will be incorporated into the overall program schedule.

The real estate process to permit Phase 1 construction work to proceed is now complete, with compensation made to all property owners affected by the Phase 1 construction, and the necessary temporary construction access licenses have been executed.

Appraisals are ongoing on the properties needed to be acquired for the Vehicle Maintenance facility, which will be an L-shaped facility near the Boston Engine Terminal in Somerville to be built in Phase 3.  As the maintenance facility and full storage yard are not needed to support initial passenger service to Washington Street and Union Square (Phases 2/2A), this phase has been scheduled to be complete some six months ahead of the date for revenue service to College Avenue (Phase 4, completion date July 2019). It is anticipated that the relocation activities of the current occupants of the maintenance facility site will be completed by the end of 2015 such that site cleanup and demolition can start shortly thereafter.
