“(T)he applicant is proposing a minor building addition of 1,300 square feet to the basement level because the specialized proton equipment required a slightly larger support space,” said Allie Smith, an associate planner with the city’s professional planning and zoning department.

Smith is referring to what would be the second proton therapy cancer treatment center between New York City and Boston, after the Connecticut Proton center in Wallingford, which is scheduled to open later this year.

Proton therapy is considered advanced radiation treatment because it uses the positively charged particles to “target cancer with exceptional precision,” reducing damage to nearby healthy tissue.

The expanded building plans for Danbury Proton are the latest development in a prolonged effort to serve western Connecticut and nearby New York residents with the novel cancer treatment.

The project, which was set to break ground on a 3-acre site overlooking Danbury Municipal Airport this spring, is “very busy marketing and selling the bonds,” a spokesman said.

“We’re ready to break ground as soon as we close on the bonds,” said Drew Crandall on Friday. “We are in conversation with investors every day and we are making good progress.”

In March, Danbury’s City Council agreed to use its bonding power to help Danbury Proton get low-cost financing under a “conduit issuer” agreement. Around the same time, the city’s Planning Commission extended approvals for the project, which were scheduled to expire in July.

All that means that Danbury Proton expects to open its 17,000-square-foot facility at 85 Wooster Heights Road in late 2027 or early 2028.

“The day is coming when we will be treating patients with revolutionary proton therapy cancer treatment,” Crandall said in a newsletter to supporters last week. “Countless patients and their families will benefit from proton therapy.”

Several businesses and residents are displaced after a well-known donut shop in Clinton caught fire Saturday morning according to fire department officials.

Clinton Volunteer Fire Department officials say officers received reports of a fire at Beach Donut where they found heavy smoke and a fire extending to the attic.

They say people were evacuated while firefighters work to bring the fire under control.

One person was transported by Clinton EMS for evaluation.

The displaced residents are being treated by the American Red Cross and the fire is still under investigation by the Clinton Fire Marshal’s Office with assistance from the Connecticut State Police Fire and Explosives Investigation Unit.

The fire department received mutual aid from several fire stations and EMS from neighboring towns.

According to the Beach Donut Facebook, the business will be temporarily closed until notice.
