The overhyped blizzard was a forecasting bust — but a boon for Sanitation Department snowplow drivers, who were still raking in the overtime Wednesday, scraping the black asphalt hours after the white stuff had been cleared from city streets.

“The city kept plowing our street in 30-minute intervals all day and well after midnight, long after the streets were snowless and plowed bare,” said Lara Vitiello, who lives on East 86th Street between East End and York avenues.

“Sometimes three trucks in a row were bumping along — with sparks flying from the plows.

“I saw them plowing nothing. I was watching and there was absolutely no snow. They just kept on plowing,” Vitiello told The Post.

Vitiello, 44, said she and her neighbors believe the only reason the drivers stayed on a job that had already been completed — was to fatten their wallets with as much OT as possible.

“We all assume this was an overtime scam that was happening everywhere [in the city]. The guys had to actually plow to get the overtime, even though there was no snow, because that’s what the OT was authorized for. It was getting me incensed last night. This is insanity. Obviously they were running up the bill,” the stay-at-home mom fumed.

Across town, other New Yorkers echoed her complaints.

“I have seen the plows pass by, put the plow down, and there is no snow,” griped Jean Luc, 60, walking on West 79th at West End Avenue

“They are overdoing it with the plowing. Where is the snow? I saw three plows going down Amsterdam Avenue and they weren’t pushing any snow. I thought it was ridiculous,” added the super of a building at West 80th and West End Avenue.

“There is no snow but they’re plowing anyway. I could hear them grinding on the blacktop. I think they are just trying to bank OT.”

Department spokeswoman Kathy Dawkins did not answer questions about why drivers continued to plow cleared streets, but she said in an e-mail to The Post:

“Today [Wednesday] we are continuing to salt and plow where necessary. The department is also opening up corner caps, intersections, removing snow from fire hydrants and bus stops. Salting and plowing where necessary [continues]. ”

And, adding a malodorous insult to injury, garbage and recycling pickups were pushed back until 7 p.m. Wednesday night — because trucks and personnel were being used for the plowing — allowing tons of trash to pile up across the city since Monday.

“They have to take it out! It’s no good over here! My customers can’t come in. Some customers come in a car and they can’t stop here to get their clothes,” snapped Ely Baeza, manager of Broadway Cleaners at 344 Broadway, where a mountain of snow-topped garbage covers the sidewalk.

Dawkins said 2,400 workers per shift had been working 12-hour shifts round-the-clock since early Monday.
