Excavation will begin in about six weeks on the 43,000-square-foot mixed-use project at 8300 Wisconsin Ave. in Bethesda.
The site, near Battery Lane, was once home to a Clarion Hotel, but in 2006 Houston developer Patrinely Group unveiled plans for a three-building luxury condominium complex to be called Trillium. Funding fell through and the site was then sold to StonebridgeCarras in March 2011 for $29 million.
The blasting that will begin in July is part of the construction of an underground garage that will be beneath the mixed-use building. The first level will be a 50,000-square-foot-Harris Teeter grocery store, according to a statement from StonebridgeCarras. Above that will be 359 apartments.
StonebridgeCarras of Bethesda is the same company developing the former parking lot on Bethesda Avenue known as Lot 31. Blasting at that site led some people nearby to think the noise and shaking buildings were due to meteors, car crashes or earthquakes.
The blasting will go on for about four or five months, depending on what workers find, said David Cerniglia, project manager. It will be on and off through those months, and should be finished by the end of the year.
Nearby residents are updated biweekly via email, Cerniglia said.
