Wynn Resorts has announced it has completed the removal of nearly 1 million tons of contaminated sediment from the former chemical plant site on which it's building a $2.5 billion Boston-area casino now to be called Encore Boston Harbor.
The cost was about $68 million, or more than double the $30 million previously estimated by the Las Vegas-based international gaming and hospitality company.
In addition to the clean up at the 33-acre site in Everett, the company also cleaned up the Mystic River over 18 months. Wynn attributed the higher costs to "increased quality measures" and other design changes.
The new casino/resort name change to Encore Boston Harbor was made following allegations of sexual misconduct against company founder Steve Wynn. Wynn, 76, has strongly denied the allegations.
The company says an additional $14 million will be spent to execute an adjacent 6-acre harborwalk and park. A June 2019 opening is currently anticipated.
