Richard Miranda, who rose through the ranks in the Tucson Police Department to become the city's top administrator, will retire at the end of the July.

Miranda, who grew up in Tucson, was hired as city manager about three years ago after previously serving as assistant city manager as well as Tucson's police chief.

He said in a memo to the Tucson City Council and upper city management sent this morning that he was ready to retire after four decades of public service in the Old Pueblo.

"My reason for making this decision is that after nearly 40 years of service with the City of Tucson, I feel that it is time to make this move for my family and me," Miranda said.

Mayor Jonathan Rothschild said in a statement this morning he was lucky to have had Miranda as a city manager for three years.

"I count myself fortunate to have had Mr. Miranda serving as City Manager these past three years. He has been a steady, stabilizing presence, well-respected by City staff and the community, whose integrity and devotion to Tucson are both exceptional," Rothschild said.

The city is likely to begin the process for a national search for a new city manager after Memorial Day weekend, Rothschild said.

Miranda, who grew up on Tucson's south side and attended Sunnyside schools, joined the Tucson Police Department in 1975.

He was named police chief in 1998. He retired from that position and was appointed as assistant city manager in 2008.

Miranda was confirmed as city manager in May 2012, but had held the post as interim since September 2011.
