West Roxbury - On Monday, Sal Zirilli was sitting on his deck when the whistle went off signaling that the West Roxbury Crushed Stone Company was going to blast; 30 seconds later, a 5-inch cube of granite shot through the woods and landed on his lawn.

That wasn't even the first time in the last week that a projectile landed on the Zirillis' Centre Lane property. Zirilli said that when he came back from vacation last week, he found a 10-inch piece of granite had knocked down a flat stonewall he had made.

Zirilli estimated that the rocks needed to travel more than two football fields to reach his property. The rocks actually had to jump out of the rather deep quarry hole, go past the spot where trees were supposed to be shielding homes, and then travel two football field-lengths through the woods.

Calls to the West Roxbury Crushed Stone Company were not returned as of the Transcript's deadline.

The Boston Fire Department came and took photos of the pieces of granite imbedded into Zirilli's lawn.

Janet and Sal Zirilli built their home 38 years ago to withstand the continual blasting of the quarry. Sal said he used wire lath instead of sheet rock, and they still have cracks in their plaster and walls.

The couple and their neighbors are used to the blasting, but they said the blasting has gotten louder and stronger in recent times.

"I was sitting on my deck. They did their whistle and did their blasting, and 20 or 30 seconds later I heard something coming through the woods,"said Sal.

Their neighbors on both sides came out immediately after the blast because all three homes shook.

Sal said he took the piece of granite to the quarry and spoke with an apologetic manager, but he doesn't expect anything to change. Sal said the quarry employee wondered whether the charge was put in wrong.

The Zirillis said they've called everyone and anyone through the years: the mayor's office; the police; the fire department; the governor's office; and so on. But they always get the same answer: the quarry is within its limits.

"You can see how severe it is when you have chunks of granite flying over the berm into someone's backyard," said Stella Kasparian, who lives on Centre Terrace. "They say they're within their limits of the blasting, but it's too high for the area because it shakes us. This is the biggest equity we have-our homes."

"We're used to the quarry," said Sal. "The dust is worse than it's ever been. It's just escalating with blasts. We can't have stones flying into our yard. I play in the backyard with my grandchildren. Imagine if they were out there. I can't have that."
