Lafayette and Moraga welcomed new leaders this week while saying goodbye to some longtime public servants.

In Lafayette, officials thanked departing council members Carol Federighi and Carl Anduri before new council members Traci Reilly and Mark Mitchell were sworn in Monday. Reilly and Mitchell will serve four-year terms. Re-elected councilman Mike Anderson was also sworn in.

Federighi announced in July her decision not to seek re-election. She joined the council in 1999 following nearly two decades of public service in Lafayette and finished her third term as mayor this month. Colleagues praised her expertise and thanked her for her leadership before Federighi took a look at her year of service, which included the passage of guidelines for downtown growth, the establishment of a massage business ordinance and regulations for wireless facilities.

"Lafayette is a wonderful community in which to live and work. We are, I believe, the envy of many others." Federighi said. Anduri also decided in July against a re-election bid, citing increased demands from his day job as a factor in ending his decade-long run on the council. He gave an emotional speech thanking everyone from his wife to volunteers, praised the level of civil discourse between residents and their elected representatives and said Lafayette was a leader in its focus on sustainability, seniors and creating a vibrant downtown core.

"The city has a golden opportunity to explore innovative solutions and be a model for others," he said.

After their swearing in, Reilly and Mitchell joined the council in electing Anderson as mayor and Don Tatzin vice mayor. Each will serve one-year terms in those capacities.

In Moraga, town leaders said goodbye to councilwoman Karen Mendonca, who lost her seat in November, and to councilman Howard Harpham, who did not seek re-election. The council reorganization followed a public comment by Lafayette resident Joan Bruzzone, who thanked outgoing council members Harpham and Mendonca for their service, before expressing her regret for the way Mendonca was treated during the campaign season when signs were posted urging voters to "dump" and "defeat" the councilwoman.

"I'm sorry you were subjected to what I consider very poor form," Bruzzone said.

Outgoing mayor Mike Metcalf lauded the town's passage of the Measure K sales tax to repair damaged roads and storm drains, and was followed by Mendonca, who listed the town's accomplishments over the past four years before giving her take on the campaign.

"In the town of Moraga it was unprecedented to witness a campaign like the one that just concluded and I hope that this election will not serve to discourage good citizens from running for local office in the future," Mendonca said.

Harpham gave a farewell speech before Metcalf was sworn in alongside new councilmen Phillip Arth and Roger Wykle. The council then elected Dave Trotter mayor and Ken Chew as vice mayor. Last year, town leaders generated a buzz when they broke with a history of how they elect their vice mayor by choosing Harpham. According to unofficial rules that designate who serves based on the amount of votes garnered in the previous election, Trotter could have been vice mayor.

Trotter and Chew will serve one-year terms.

On Dec. 4, members of the Orinda City Council selected Amy Worth their new mayor and Sue Severson as vice mayor.
