Manufacturer ASML came before Wilton's Planning and Zoning Commission May 23 to apply for a permit to build a three-story parking garage at the site of its 77 Danbury Road plant.

The garage would be located at the northwest corner of 77 Danbury Road, which is removed from Route 7 but adjacent to Metro-North's railroad tracks.

Casey Healy of Gregory and Adams and attorney for the applicant explained that because construction of the garage would involve reconfiguration of a portion of the existing surface parking lot, the 488-space structure would mean a net increase of 306 parking spaces.

Engineers with HLW International developed the project plan and attended the meeting, and they said the project would involve new sidewalks and crosswalks, drainage enhancements, the addition of rain gardens, and a comprehensive landscape design.

The proposed site is not visible from Route 7 because of a rock outcropping, but it would be visible from the Metro-North train tracks, and the design team proposed an internally illuminated ASML logo sign on the top floor of the structure so that Metro-North commuters could see it.

Town Planner Bob Nerney explained that Wilton's zoning regulations forbid internally illuminated signage.

One member of the public spoke at the public hearing out of concern for his Chessor Lane property, which is west of 77 Danbury Road and close to where the new garage would be built.

"[ASML's] HVAC units used to run fairly quietly throughout the day," he said. "Over the last couple of years, there's been a noticeable increase in noise level with the HVAC units."

He was also concerned about lighting.

"There's an inevitable increase in light that's going to be an intrusion into the neighbors on Chessor Lane and over on Mcfadden Drive, and maybe other areas as well," he said.

The Planning and Zoning Commission continued ASML's public hearing to June 13, so that the applicants could have time to respond to staff comments and commissioners' questions.
