The Village of Pelham Manor “expressed its disappointment” to Mount Vernon city officials over noise levels from a concert at Hutchinson Field on Sunday, calling the event “a major step backwards” in the village’s relationship with the city, according to a statement Monday on Pelham Manor’s Facebook page.

“The village is aware that yesterday’s event at Mount Vernon’s Hutchinson Field caused excessive noise that impacted the quality of life for our residents,” the statement said. “This was a major step backwards in our relationship with the city and the assurances they gave with regard to noise control.”

After weeks of debate and negotiation, Pelham Manor had days earlier expressed hope a resolution had been reached between the village and the city over the concerts. A statement published on the Pelham Manor Facebook page Saturday said Manor officials didn’t expect noise violations, though they did provide residents with police  phone numbers to contact.

Mount Vernon officials agreed in a meeting to take steps to reduce noise, including incorporating specific limits in event permits and orienting speakers away from the Manor, Pelham Manor said in a July 5 statement. An event held July 7 produced no major noise complaints.

The meeting was set up after a phone call between Pelham Manor Mayor Jennifer Monachino-Lapey and Mount Vernon Mayor Richard Thomas seemed to get things off to a rocky start.

Thomas said on the call that noise levels were “not too high two blocks away in Mount Vernon.”

“We’ve lowered (the sound levels),” Thomas said. “We’ve been compliant on our side.” Mount Vernon is “committed to mitigations for sound,” he said. He proposed consulting sound engineers to determine the cause of the sound being heard in Pelham Manor. Additionally, Thomas recommended soundproofing by constructing a “soundwall.”

Pelham Manor’s statement Monday said another meeting would be held between Pelham Manor officials and representatives from Mount Vernon.

At the same time as the debate takes place between the two localities, questions remain over the crisis within the Mount Vernon government. In the past week, Mount Vernon has faced debate over who is the rightful mayor, with the elected Thomas and former City Council President Andre Wallace both claiming the title. Thomas accepted a plea deal from prosecutors last week over campaign finance violations that ordered his resignation effective late September. But Wallace and the city council interpreted the Mount Vernon charter as saying that when convicted of any crime, an officeholder loses their right to hold the position. This led to Wallace’s appointment as mayor.
