The Riverbrook Regional YMCA has won approval from the Planning and Zoning Commission for permits to expand the building and parking, the first major upgrade in its 45-year history.

The approval was given in a unanimous vote of the commission Dec. 11 at the Wilton Library’s Brubeck Room.

The project drew no opposition at a brief public hearing. Resident and newspaper columnist Stephen Hudspeth spoke in favor of it.

“We all know how the YMCA does things to make Wilton a wonderful place to be,” Hudspeth said, urging approval.

The YMCA is now 66,310 square feet, and it wants to add 11,955 square feet, for a total of 78,265 square feet, according to the application on file at the town hall annex.

The facility at 404 Danbury Road also wants to expand its parking of 199 spaces by 18.

A spacious wellness center overlooking the grand lobby equipped with strength and cardio-training equipment to empower people to promote healthier decisions is planned.

Modernized locker rooms with large family changing areas and accessible space for seniors and people with special needs is part of the plan.

A bright, two-story atrium-style lobby will serve as a community hub where people may connect and engage with one another.

Four dedicated group exercise studios will deliver a variety of classes for all ages and abilities that support physical and spiritual strength.
