Hi Everyone:
CENTRAL SUBWAY TUNNEL BORING MACHINES (TBMs) & NORTH BEACH
Feel free to write Supervisor David Chiu and his staffer Judson True.
David.Chiu@sfgov.org, Judson.True@sfgov.org
1. Thank them for agreeing to answer Paul Foley’s 1-28-13 questions BELOW.
At the 1-22-13 Community Meeting, the fire alarm ended questions & answers.
2. Ask for another Community Meeting to see TBMs final plans and to ask questions.
People seem to be learning details from the news, like Matier & Ross’ 1-30-13 article:

EXTRACT TBMs IN CHINATOWN OR BURY TBMs
It is illogical for the Central Subway to spend $80 million for a northern tunnel extension and Pagoda Theater costs to get $4 million in TBM salvage value. Instead, per the original plans in 2005+, the TBMs can be extracted or buried in Chinatown, saving $80 million, reducing construction liabilities and eliminating all disruptions to northern Chinatown and North Beach. Other subway projects bury TBMs.
BRISBANE: Subway project is burying two TBMs.

NEW YORK CITY’s new subway construction is leaving TBMs in the ground for cost-savings.
