On Tuesday, Feb. 21, the Piedmont City Council (see 10 minute mark of video) voted unanimously to hire Antioch Assistant City Manager Rosanna Bayon Moore as their new city administrator. Item 3 of the regular meeting agenda it reads, “Consideration and Adoption of a Resolution Appointing Rosanna Bayon Moore as City Administrator and Approving the Employment Agreement Between the City of Piedmont and Rosanna Bayon Moore.” Please see Item 3 of the attached or here – City of piedmont (

She will be paid an annual salary of $275,000 plus any cost-of-living adjustments to lead the 11,270-person city.

After serving as city manager in Brawley, CA for nine years, Bayon Moore was hired by former Antioch City Manager Ron Bernal in September 2020 in what appeared to be part of his succession plan 15 months before his retirement. But instead of promoting her to the position of interim and then permanent city manager, the Antioch council voted 3-2 to hire retired San Francisco Police Lieutenant Con Johnson as interim city manager. They then made his position permanent last fall in a three-year contract.

Questions for Antioch City Manager Go Unanswered

The following questions were sent Friday evening Feb. 17 to Antioch City Manager Con Johnson and all five council members: Do any of you have a comment on the departure by Assistant City Manager Rosanna Bayon Moore to become the new Piedmont City Administrator as of their council vote Tuesday, Feb. 21? How long were you aware of her pursuits of the new position and possibility of losing her experience and expertise from the city staff? Is there a plan to hire her replacement? Will that include using an executive search firm for a possible nationwide search? Or do you have someone in mind from the current city staff? Has there been any thought to combining the positions of Assistant City Manager and Economic Development Director as the City previously had?”

Barbanica Calls it a Huge Loss for the City, Wants Nationwide Search for Replacement

“This is a huge loss for the city,” District 2 Councilman Mike Barbanica said when reached for comment. He was the only council member to comment on Bayon Moore’s departure. “It’s Piedmont’s gain but our loss. I’m very sad to see her go. I’ve worked with a lot of city managers and assistant city managers in Pittsburg and here, as well and I can tell you she was a fantastic assistant city manager.”

“One thing I respected about working with her, she’s not intimidated by positions on the council, or the mayor and she’s not afraid to tell any of us ‘no’. She’s willing to stand up for what she believes in and knows to be the best thing for the city.”

Asked how long he knew about this he responded, “About 10 minutes” having first been informed by the media.

Asked if he supported having a nationwide search using a professional recruiting firm for a new assistant city manager Barbanica said, “I absolutely do. I just want the best person for the job.”
