Kotzuba
was one of the central figures in the debate over the city's move
toward all-permit parking, which was announced in May but delayed as
the city fine-tuned regulations in response to criticism from residents.

In
an e-mail to city employees, Mayor Joe Curtatone credited Kotzuba's
leadership "at a time of rapid change and extraordinary challenges."

"Jim's
dedication and expertise will be missed, but I hope you will join me in
congratulating him on this wonderful new opportunity," Curtatone said.
"[T]he fact that our managers are sought out by other employers is a
reminder that Somerville enjoys a strong and growing reputation as a
leader in municipal governance and best practices."

In an e-mail, Kotzuba said, "It was not an easy decision but I think it is a great opportunity for me and my family."

Kotzuba
has served as acting director of Traffic and Parking since 2005. Prior
to taking the position, he worked in client relations for Mellon
Financial Corporation in Everett.
