Tom Miller's last day at the Portland Bureau of Transportation will be Feb. 4 Tom Miller's last day at the Portland Bureau of Transportation will be Feb. 4

Tom Miller, Portland's transportation director, submitted his letter of resignation to Mayor Charlie Hales on Wednesday.

"Per your request, please accept my resignation from the Portland Bureau of Transportation," Miller wrote in a three-sentence letter. "You have made clear that your request for my resignation is in no way related to my performance, rather your desire to take the bureau in another direction. My final day will be February 4, 2013."

Miller rose to Transportation Bureau director in 2011 after serving as former Mayor Sam Adams' long-time chief of staff. Adams declined to complete a national search for the job, which comes with a $150,000 salary. Miller previously made about $100,000 as chief of staff.

Hales, who frequently criticized the Transportation Bureau's management on the campaign trail, was

as mayor Wednesday morning. All of the city's bureaus must submit their budget requests to Hales on Feb. 4 -- hence Miller's end date.

Also Wednesday, a spokeswoman for the city's Department of Human Resources said there was no severance package available for Miller.
