San Antonio's City Manager announced that she will be retiring after 13 years of service.
Sculley's retirement will go into effect no later than June 30, 2019, according to a release from the city.
"I think by now, with a number of things in place and how the city is moving forward, it's a good time for me to move on," she said on Thursday.
Sculley served under four different mayors, supervising more than 12,000 employees and a $2.7 billion budget in the process. She often received the credit for improving city finances and helping to shepherd three massive bond packages.
But San Antonio Councilman Greg Brockhouse, who called for Sculley's resignation earlier this month, described her decision as fallout from Election Day 2018.
"There was too much power in the city manager's office and it needed to change," he said. "The public spoke loud and clear, and I think Sheryl Sculley heard it. I thank you (Sculley) for your time, period, but we need to look into the future about what's best for the community and show some leadership.
Earlier this month voters approved Proposition B, placed a term limit and salary cap on future city managers.
"It's not about replacing Sheryl Sculley," Brockhouse said. "What this is about is what we're going to do as leaders, as city council members, to run this city."
Sculley previously served as assistant city manager of the City of Phoenix for 16 years and city manager of Kalamazoo, Michigan for 15 years.
