BROOKLYN - Mayor Michael Bloomberg has announced an aggressive plan to expedite a hefty backlog of NYCHA repairs.

City officials say they want to eliminate more than 400,000 open work orders in public housing buildings across the city by the end of this year. The plan includes new operational processes and hiring some new staff.

The housing authority said another goal is to reduce the average wait time for repair work to one week for minor problems and two weeks for repairs that require a tradesman.
