Only one obstacle left before Steve Wynn can finally build his Boston Harbor project.

On Monday, city officials issued a building permit to casino operator Wynn Resorts for its proposed $2 billion casino development in Everett, the Boston Herald has reported. Mayor Carlo DeMaria called the permit “a major milestone” for the casino company, and “another positive step forward for Everett and beyond.”

There wasn’t a doubt that the city, which had been eagerly waiting for the project to proceed “for years,” will greenlight the casino development. But the permit also signifies that Wynn is all set to build the “24-story curved-glass hotel and vast casino,” provided that it clears the final regulatory huddle—Somerville Mayor Joseph Curtatone.

Early this year, the casino operator was forced to put on hold work on the site, including the removal of contaminants such as lead and arsenic on the long-condemned 33-acre site, after Curtatone filed an appeal questioning the environmental permit that Wynn Everett received from the Department of Environmental Protection.
