Delta Development of Downers Grove would like to build the 120-unit facility for seniors on a wooded lot on Lacey Road facing residential streets. The project has not yet gone to the village’s planning commission, where it would have to be approved before going up for a vote at the Downers Grove Village Council.

Much of the discussion from residents focused not on the proposed project, but on years of frustration with Donegal Excavating, a construction company that sits next door to the wooded lot.

The construction company operates on a residential zoned lot, and many neighbors say large diesel trucks and other construction equipment rumbles in and out of the property late at night, despite their complaints to the village.

Some neighbors said combining vehicles from Delta’s facility with Donegal’s trucks could make a bad situation worse.

“I’m for (the development) … but I don’t want to see more cars, more traffic, especially with Donegal,” said Lacey Road resident Nick Janowitz.

Delta’s attorney Michael Fiandaca said the facility could push Donegal to operate in a more neighborhood-friendly manner, because the facility’s state license comes with quality-of-life standards that could give it leverage to pressure the construction company.
