LEVELOGGERS

• We continue to upload dataloggers at the following locations on a weekly basis:
  • 1 on and around Saint Charles St. and 2 on Cazenove Street
  • 5 on Beacon St., in the Berkeley to Clarendon St. block
• 12 dataloggers have also been installed in the Back Bay, South End, and the Fenway
• The MBTA has agreed to send me down on their tracks with a couple of their flagmen for me to access the OW’s adjacent to the alignment. I’m in contact with Terrence McCarthy of the MBTA and hope to gain access soon.

CONTOURS

• We continue to generate contours for all areas of our well network. Elliott and I have reviewed them with our technical committee.
• We will continue to receive the contours from BWSC and will be sending them our contours for comparison.

ISD RESEARCH

• We continue to look for building permits and any underpinned buildings.
• I have completed all of Back Bay, Lower Beacon Hill, Chinatown/Leather District, and Bulfinch Triangle. I continue working on the Fenway.
