Quatrevaux, whose current term ends on October 19, said he will "explore retirement for a third time."
“Since 2009 the OIG drove dramatic improvements at Louis Armstrong New Orleans International Airport and the New Orleans Police Department and exposed the dysfunction at the Sewerage and Water Board.
“My vision is a New Orleans in which all citizens trust the OIG to ensure the integrity of local government and to provide credible and reliable information about government performance. To that end, I had planned to assist in the transition to new leadership,” Quatrevaux said in a statement. "Unfortunately, unexpected health events require that I take extended medical leave."
During Quatrevaux's tenure as inspector general, he helped to root out more than $95 million in waste.
The New Orleans native took the job in 2009 and quickly began to focus on inefficiencies in local government.
The office's audits over this two terms helped to identify more than $25 million in contract waste at the airport. He uncovered millions in standby and overtime spending that could be cut from the sewerage and water board. He also helped to create reforms at the New Orleans Police Department by recommending more officers leave the desk and respond to calls on the streets.
Quatrevaux's reports also helped create meaningful reforms in the police department after identifying under reported sex crimes.
The office now will monitor the city's $22 million catch basin cleaning project.
