Portland's chief administrative officer, Tom Rinehart, on Wednesday dissolved the Bureau of Internal Business Services, a little-known bureau responsible for overseeing the city's fleet of 3,150 vehicles, 3.5 million square feet of buildings, printing and mail delivery operations, and risk management.

As part of the restructuring, the bureau's longtime director, Bryant Enge, announced in an email to Portland elected officials and bureau executives that he is leaving city government. It's unclear if Enge will receive a severance package for his exit and, if so, how much it would be worth.

Enge's leaving makes him one of a growing handful of city bureau directors who have left their jobs since Mayor Ted Wheeler took office last January. Eight directors left last year -- three were pushed out -- leaving the city to pay more than $700,000 in severance.

In an email sent Wednesday to the city's elected officials, Rinehart said that in light of the Portland's record-high revenues, he has encouraged city bureau leaders to "prepare to do business very differently." Employees within the Bureau of Internal Business Services will be shuffled within other branches of city government, Rinehart said.

"The fact that we are now in our fifth straight year at a record level of revenue collection and yet are still facing budget cuts is a clear sign that, as a city, we need to re-think how we are organized, what services we will be able to continue, what processes we change, and what services we stop doing completely," wrote Rinehart, who previously worked as Wheeler's chief of staff.

Last year, the Bureau of Internal Business Services' had a budget of $103 million and employed 163 people.
