The parents of the youngest first responder killed on 9/11 were to get a special tribute this year — a motorcycle parade past their Queens home in honor of their son, Richard Pearlman.

But Betty Braton, the head of the local community board, put up a roadblock on a route change for Sunday’s annual “Run for Richie,” upsetting his family, parade organizers and leading to a petition calling for her ouster.

The annual motorcade began in 2016 to benefit the Forest Hills Volunteer Ambulance Corps and to pay tribute to Pearlman and others killed in the terrorist attack. Some 2,000 motorcyclists have participated along with emergency response vehicles on a route that usually goes from Aqueduct Racetrack into Manhattan.

Now, on the 20th anniversary of the attacks, organizers wanted to detour the motorcade past Pearlman’s Howard Beach home, where his parents still live.

Pearlman, 18, had just graduated from high school and was working for a lawyer who had sent him on an errand to 1 Police Plaza in Lower Manhattan on the morning of Sept. 11, 2001. While there, he heard an “all hands needed” announcement over the public address system about a plane hitting the World Trade Center.

Pearlman, who volunteered with the Forest Hills ambulance corps and was a first aid instructor, went to Ground Zero with NYPD Officer Moira Smith, who would become the only female NYPD cop to be killed that day.

A photograph published in Newsweek captured Pearlman wheeling a bloodied victim as medics attended to her before the towers collapsed.

Pearlman’s body was recovered six months after the attack.

Pearlman’s sister, Lisa Pearlman-Mason, 41, said she and her husband would participate in the annual parade on a motorcycle. Her parents, Dorie and Barry Pearlman, are usually at the racetrack starting point, but not this year because of COVID.

“I would love for my parents to see everybody come by. It’s 20 years,” she said. “My brother’s now dead longer than he was alive. It’s like a nightmare that we live everyday.”

An organizer, Paul “PJ” Marcel, said the NYPD told him before Labor Day weekend that the route change was authorized and was just awaiting one last approval.

But Marcel said after the holiday he found out that Braton had raised objections, saying the parade would disrupt church and synagogue services. This despite local houses of worship being on board with the event and even offering prayers, Marcel said.

“She is the head complainer of the neighborhood,” said Marcel, who started the petition drive to give Braton, who has headed Community Board 10 for 29 years, the boot. “She needs to go.”

The petition had garnered more than 600 signatures.

Marcel called Braton’s interference “blatant disrespect for a fallen hero from Howard Beach.”

Rev. Francis Colamaria, pastor of local St. Helen’s R.C. Church, said a priest was set to bless the parade.

“It’s a good cause,” he told The Post.

Braton told The Post that while community boards have no official role in the parade permit process, she was merely passing along local concerns about the motorcycles overwhelming residential streets. She said she also told the NYPD that there was a church and synagogue along the route.

“I understand that I’m the Wicked Witch of the West this week,” she said. “My job is to deal with community issues. Concerns were raised. I expressed the concerns, which were valid.”

Braton said if the parade organizers had approached her sooner then perhaps a compromise could have been reached, but it was too late to come to any agreement this week.

“We have a lot going on this week that I have to pay attention to as well,” she said. “This is not the only thing I’m paying attention to. There was a storm.”

The NYPD said that because of “the size and magnitude of this parade, which includes thousands of vehicles, rerouting the parade down a residential street would pose traffic and safety hazards to the residents.”
