I-90 Interchange Project

I-90 IRT Rendering of Hybrid Variant look West from the Paul Dudley White Path

CRWA has been actively involved with the shaping of the Allston I-90 Interchange Improvement project as part of the MEPA appointed Task Force. We recently submitted our comments on the Independent Review Team's (IRT) report on their analysis of the three options for the "throat" area. These comments were preceded by a presentation made by Pallavi Mande, our Blue Cities Director, outlining CRWA's priorities for the project and our preferred option for the "throat". The above graphic is the IRT's rendering of the "hybrid variant" looking west from the Paul Dudley White path along the river.


Oil spill in the Charles River 

20181206_oil spill photo-1 

An oil spill was reported in the Charles River on Wednesday, December 5th behind the Shaw’s grocery store located at 130 River Street in Waltham. The Waltham Fire Department responded to the call and contained the discharge from a drain outfall. Massachusetts Department of Environmental Protection (MassDEP) sent a contractor to clean up the drain. MassDEP and Mass State Police investigated the source of the oil spill and discovered that the oil came from the private property Pro-Tech gas station. Pro-Tech was responsible for previous oil releases in 2004 and 2017. The U.S. Environmental Protection Agency was notified of the spill.

We are grateful to the Waltham Fire Department and MassDEP who acted quickly to contain and clean the spill. Without this rapid response, the spill could have spread far downstream, harming fish in the river and plants along the banks. Incidents like this are stark reminders of the work we still have to do to ensure the Charles River is protected.
