Manhattan Borough President Gale Brewer has a solution to Mayor Bill de Blasio’s claim there aren’t enough cops to turn streets into socially-distanced play zones during the COVID-19 pandemic: Don’t use cops.

Brewer told The Post a group of Manhattan Business Improvement Districts is proposing turning Broadway into a miles-long pedestrian plaza that would be patrolled and maintained by employees of the local business improvement districts.

“They don’t need police officers, they want to do it themselves,” she said. “They already have their security people out. They already have their sanitation out. All they need is the barricades.”

Brewer said the move would be a boon for local businesses on Broadway, which expect to rely heavily on outdoor space as the city gets back on its feet from the coronavirus pandemic.

“There is the general feeling that people aren’t going to want to be in a crowded restaurant,” she said.

News of Brewer’s push, first reported by Streetsblog, came as Oakland, California Mayor Libby Schaaf announced plans to close 74 miles of streets to car traffic “so that bicyclists and pedestrians can spread out and take in fresh air safely.”

Schaaf’s announcement on Friday added Oakland to the growing list of cities that have converted at least four miles of streets to pedestrian-only — including Boston, Philadelphia, Minneapolis and Denver.

De Blasio nixed New York City own’s pandemic street closures after less than two weeks, citing a shortage of cops to enforce social distancing.

The mayor reiterated that justification on Friday.

“We’re going to keep looking at it,” he said. “If you close off a block, people have an impulse to come out and gather.”

“I think that makes a lot more sense when we have more of our enforcement personnel back than we would right now.”
