Onondaga County economic development chief Bob Petrovich announces retirement

Onondaga County is losing one of its main economic development hands just as the Micron project, sewer expansion and housing planning are converging around the county’s northern growth corridor. County Executive J. Ryan McMahon announced June 12 that Bob Petrovich will retire, with no retirement date included in the release.

Petrovich has been listed by the county as deputy county executive for economic development and planning, a role that put him at the center of the county’s biggest development decisions. He was a key figure in the Micron process, helping guide the project through final environmental review and incentive approvals that county officials said cleared the way for groundbreaking.

Micron announced its $100 billion semiconductor campus in Central New York in October 2022 and broke ground Jan. 16, 2026, on a site in the Town of Clay that county officials say will reshape the regional economy. The county has said the deal includes the transfer of 913 acres of land and roughly $2 billion in tax breaks, underscoring both the scale of the project and the financial commitments tied to it.

Petrovich’s retirement comes as Onondaga County is still building the infrastructure needed to support Micron and the population growth expected to follow. In December 2025, county lawmakers approved a record $549 million expansion of the Oak Orchard Wastewater Treatment Plant, which is expected to increase capacity from 10 million gallons a day to 15 million gallons a day. In May 2026, New York said it would contribute $115 million toward sewer plant expansion tied to Micron and growth in Syracuse’s northern suburbs.

The leadership change also lands during a broader shift in county development politics. In May 2026, Democrats in the Onondaga County Legislature moved to add new members to the Onondaga County Industrial Development Agency, the county’s key economic development arm. That effort signaled fresh scrutiny over the agency that has helped steer major projects like Micron and other large-scale investments.

For county leaders, Petrovich’s departure raises a practical question more than a symbolic one: how to keep major projects moving without slowing approvals, housing coordination or infrastructure work already underway. With Micron breaking ground and the county still racing to expand sewer capacity, the next economic development lead will inherit a region in the middle of a long and costly buildout.
