After filling more than 8,800 truckloads and 4,300 railcars over seven months, Wynn Boston Harbor announced last week that the last pile of excavated contaminated soil was removed from its construction site in Everett.
The ‘bottoming out’ of this $2.4 billion project marks the completion of one of the largest and most complex urban construction excavations in recent New England history, said Wynn Boston Harbor in its latest project update.
More than 630,000 tons of contaminated soil were safely and successfully transported to licensed landfills across the country to accommodate the below-grade levels of Wynn Boston Harbor and to make the 33-acre site suitable for a waterfront park and public use.
The entire site remediation cost $30 million and is funded 100% by Wynn Boston Harbor with no tax dollars or public funding used for the cleanup.
With the contaminated soil removed, the next phase of site remediation will be the dredging of soil around the shoreline and the creation of a living shoreline.
Native plants will be placed in the living shoreline to help with the natural cleanup of the Mystic River and to help hasten the return of native fish and birds to the area, said Wynn Boston Harbor.
