American Canyon City Manager Dana Shigley resigned Tuesday from her post at the behest of the City Council.

Public Works Director Jason Holley was expected to be named interim city manager while the council searches for a replacement for Shigley.

Shigley, 54, announced in September that she was retiring, but would stay on as city manager until council members chose her successor.

That plan changed following her Sept. 19 announcement.

“Subsequent to my announcement, the City Council decided that it would be in the City’s best interest to appoint an Interim City Manager while they recruit for a new City Manager,” Shigley wrote in an email Tuesday evening.

“Thus, today was my last day as City Manager in American Canyon.”

Shigley said she would “stay around until the end of the year in an advisory capacity as needed.”

The city manager, who has helmed city operations since 2012, was absent from the council’s Oct. 3 meeting, and from a special online town hall meeting held Tuesday to inform residents about the Napa County fires.

The council met in closed session Tuesday afternoon to discuss the appointment of an interim city manager. Holley was expected to fill this role, with an announcement coming sometime Wednesday.

Shigley wrote in her email that she was looking “forward to spending more time with my husband, cats, baking sheets, roses and sewing machine. And maybe a few more trips to Oregon,” where she often vacations.

She previously said that she and her husband had purchased a home in Santa Rosa and intend to move there after she leaves City Hall.

“It has been a great pleasure serving American Canyon, working through challenges and celebrating our successes,” she added. “At the end of the day, though, my only mission is to leave the community in a better place than when I found it. I hope I have accomplished that for you.”

Prior to taking over as city manager in January 2012, Shigley served in a variety of positions, ultimately city manager, with the city of Anderson, a Central Valley community with a population of about 10,000.

“Overall, I think my focus was on reconnecting with the community and tremendously improving our relationship with the community,” Shigley said Sept. 19. “We do a much better job of informing our community about what is happening and soliciting their feedback. We haven’t met all our community goals, but our residents know what is going on and can get involved.”
