Assembly Square developers outline potential traffic impact by Dan Murphy
Representatives for the Assembly Square development in Somerville appeared before the Charlestown Neighborhood Council last week to outline the project?s expected traffic impact, as well as several proposals to help remedy the situation.
?There is no getting around that this project will create a lot of traffic, and the way the roadways are today can?t handle the traffic,? said Patrick Dunford, a project manager for Watertown-based Vanasse Hangen Brustlin Inc. ?But we hope to keep the traffic on major roadways, so there is no spillover into the surrounding neighborhoods.?
Federal Realty Investment Trust of Rockville, Md., plans to convert a 50.2-acre site in Assembly Square into a mixed-use area that would include approximately 2,100 residential units, 1.7 million square feet of office space and more than 800,000 square feet of new retail space. Retail space would include a cinema, a 200-room hotel and a 340,000 square-foot IKEA home furnishings store. The project?s multiple phases are expected to take approximately 10 years to complete and cost more than $1.3 billion, according to project consultant Tom McShane.
To help reduce traffic, Dunford said the developer plans to reconfigure seven roadways and add new signals at these locations, including two additional signals on Lombardi Street.
Dunford also said that the signals would be linked together to help facilitate the traffic flow. ?Each signal essentially knows what the other is doing,? he said.
The developer had also struck a deal with the Massachusetts Highway Department, whereby existing signs would be modified to help direct commuters to Assembly Square.
?We?re still trying to get additional signage for IKEA,? Dunford said.
Another proposal to alleviate traffic in the area is the creation of a one-mile expansive roadway in the middle of the site to help absorb vehicles, Dunford said.
In addition, Dunford said he expects the traffic impact on Sullivan Square would be minimal, since most vehicles traveling southbound to the site would take exit 28 off of I-93. A thorough review of the arrival patterns indicated that 25 or fewer vehicles would travel to and from IKEA through Sullivan Square, compared with the 3,600 and 5,200 vehicles that already travel through Sullivan Square during those times, he said.
McShane said IKEA would provide free shuttle service to Assembly Square from the Sullivan Square or Wellington MBTA station until the new MBTA station at Assembly Square opens in 2013. The service would run on weekends and some weekdays, depending on demand, he said.
Meanwhile, Dunford said he expects the traffic study would be finalized later this month and, at that time, the developer would share its findings with the city to assist in the city and state?s Rutherford Avenue Corridor Study.
