South Burlington City Council Chair Pam Mackenzie resigned today.

“It is my understanding that Pam has a very attractive professional opportunity out of state that she has accepted,” Kevin Dorn, the South Burlington city manager, announced in a news release. “On behalf of all of our city staff I want to wish Pam the very best of luck in her future endeavors and thank her for her leadership and service to the community."

In a letter of resignation addressed to Dorn, Mackenzie wrote, "Unfortunately, I can no longer devote the time required to do my job as Chair, and member of the South Burlington City Council."

She thanked Dorn for his leadership and noted that her resignation was effective today.

It was just last March that Mackenzie was reelected to the council, beating challengers for a three-year term to keep control of the body in the hands of a more conservative faction. She has been a contentious figure at times in a city where politics have been polarized, with suburban-style conservatives clashing with residents who hold more liberal views.

Seven Days recently reported that the state attorney general's office is still investigating an allegation that Mackenzie violated the law through a political action committee she formed to influence local elections.

Mackenzie could not be reached for comment.

The council can appoint Mackenzie's replacement, who would serve until March, when voters will elect a candidate to finish out her term. The council plans to meet soon on the matter.
