Green Line Extension Pre-Construction Survey

Purpose of Work: Capture conditions of homes and businesses along the alignment to ensure no adverse structural impacts are caused by construction.

Approach: Document conditions in the ROW first, beginning April 16. In late April/early May begin notifying homeowners and requesting access to their properties (inside & out) to perform visual, video, and photographic survey of structures. Notification process will be ongoing throughout 2018. Like the tree clearing work, the survey will start on the east side of alignment and will progress from north to south.

We will be completing surveys from north to south, a more detailed schedule of when we will be in your neighborhood is provided below LINK TO SCHEDULE,

Duration: Surveys will take approximately one hour to complete per property. Work will continue throughout 2018. CLICK HERE TO LET US KNOW WHEN YOU CAN HAVE A SURVEY DONE

Impacts: Some time involved on the part of homeowners to allow for property access and coordination, etc.

Benefits: Homeowners will receive a report of the survey results. This operation will help to ensure that any potential impacts to properties from construction are captured.

Areas impacted in next two weeks: Homeowners on the east side of the MBTA right of way will start to receive certified letters from PEER Consultants.
