THORNTON, Colo. — If you look behind Thornton’s Windemere neighborhood you can see forever. It’s the city of Thornton’s job to keep it looking that way.

“I was sitting down watching television and all the sudden I heard this bang,” said Deno Kalomos. He knows when the city mows and he knew this time that wasn’t the sound he heard.

“I was like what the heck was that? I went outside and I saw this hole up there,” said Kalomas.

It was from a rock that the mower’s blade shot 15 feet in the air breaking the family’s window.

“(The city) was just mowing way too close.”

Kalomas said the mower acknowledged he caused the damage and asked Deno to file a claim.

After nearly eight months, the city laid down the law.

“The third time I got a hold of somebody she told me to deal with it. It was the law,” said Deno’s wife Leslie.

The city’s insurance company also denied the claim citing governmental immunity. It’s a law aimed to benefit taxpayers by keeping the city from having to pay huge settlements unless the city is negligent.

The city of Thornton’s public information officer Todd Barnes issued a statement saying, “We will not be providing any official statements for this story.”

“It’s horrible,” Leslie Kalomas said. “We are both disabled and can’t afford to replace the window. We expected more.”
