Welcome to New York, Greg Russ!

One New York City councilwoman is greeting the Housing Authority’s new chairman with a broadside demanding improved oversight over still-ongoing Superstorm Sandy Reconstruction work at Lower East Side developments, following a crane collapse and other fiascos.

The letter from Lower East Side rep Carlina Rivera to Russ, who starts on Monday, comes a week after the partial crane collapse at the Jacob Riis Houses, which forced the evacuation of two of the complex’s apartment towers.

It was the latest in a string of Sandy-related NYCHA snafus in her district, the fed-up Manhattan Democrat told The Post. Construction crews also busted a gas line at the Baruch Houses.

NYCHA’s own website shows residents there have been without since April and that it won’t be fixed until October.

“We need an audit of the FEMA [Federal Emergency Management Agency-funded] work that’s going on,” Rivera said. “We have no confidence that it is going to spent responsibly or even with public well-being in mind.”

“It’s a construction zone, it’s standing water, it’s uncovered debris everywhere,” she added. “I just find it completely unacceptable.”

New York City scored more than $14 billion from the Feds to help rebuild sections of the city — like the Lower East Side — ravaged by Superstorm Sandy in 2012 and toughen protections against future storms fueled by climate change.

NYCHA set aside $344 million of the money for the Riis Houses and Baruch Houses, which sit just a few hundred feet from the East River and were badly flooded by the mammoth storm. The construction work is expected to be wrapped up in early 2022.

Rivera’s blistering Friday letter is just one of many headaches Russ — who most recently headed Minneapolis’ public housing agency — will have to deal with when he starts his new job Monday.

He’s come under intense scrutiny for his $403,000 paycheck , his plan to fly back to Minnesota to see his family on many weekends and his refusal to visit NYCHA in July because the city couldn’t pick up the tab.

“We ask you, Mr. Russ, as the new leader of a housing system with a population the same size as the entire city of Minneapolis: how can you already decide that being out-of-state in Minnesota every weekend is workable for your new position when you have not yet set a foot on a single development in our city,” she wrote, blistering his “weekday warrior” status. “And don’t worry, my District is just 45 minutes from JFK, so it shouldn’t interfere with your busy flight schedule.”

In a statement, NYCHA promised that resident safety is “paramount” but did not commit to any additional review of the projects.

“Our residents’ safety is paramount, and NYCHA remains committed to being both transparent and accountable as we work to make sure public housing is more resilient to future storms,” said authority spokesman Chester Soria.
