Kathryn Garcia's first day on the job as interim head of NYCHA was a busy one. 

Garcia visited the Queensbridge Houses, the largest public housing development in the nation.

The public housing authority had said Garcia would spend the day with maintenance crews making repairs across the city as part of its "Saturday Blitz" efforts.

Garcia is temporarily leaving her role as sanitation commissioner while the de Blasio Administration finds someone to permanently head NYCHA.

Last month, the Trump administration and federal prosecutors signed a consent agreement to install a federal monitor at the housing authority.

Garcia's job for now is to make sure the city starts immediately complying with the new agreement.
