The Upper Falls Greenway plan got a unanimous "thumbs up" from the Board of Aldermen's Finance Committee this week.  The Finance Committee needed to approve a request from the mayor for the purchase of an environmental insurance to cover the proposed park.  There are still two remaining votes by the aldermen coming up - one from the Program & Services Committee followed by a vote by the full board.  Once that's done, the city will be able to sign a lease for the property with the MBTA.
