Marin County shifts purchasing authority to Finance, raises delegation thresholds to speed contracts

Marin County on Tuesday voted to move the county—uying function to the Department of Finance and raise the dollar thresholds used to approve contracts and purchases, a change officials said is intended to speed routine procurements while strengthening oversight of higher‑risk deals.

The board appointed Finance Director Mina Martinovich as the county—uying agent effective July 1 and approved a delegation framework that raises department head authority for routine purchases from current lower levels to $50,000, places procurement authority from $50,000 to $200,000 with assistant county executives and the purchasing agent, and reserves approvals above $200,000 for the Board of Supervisors. Dan Ilerman, assistant director of finance, described the package as a phased modernization meant to align procurement approval with fiscal stewardship.

"We're not reducing oversight," Ilerman said. "We're building structure: routine, lower‑risk items can move faster at the department level, and higher‑risk procurements receive more rigorous executive review and continued board oversight." He said competition requirements, documentation, internal controls and quarterly delegated reporting will remain in place.

Procurement Manager Adrian Sahadio walked supervisors through the implementation plan and procurement methods mapped to the new thresholds. Departments will use an intake form and an executive memo to justify midrange purchases ($50K–$200K); assistant county executives can "port" items to the board when issues rise to policy significance. A technology solution for contract tracking and dashboards is planned after policy and workflow updates are in place.

Board members asked how the public and the board would see delegated approvals going forward and how the county will favor local and small businesses. Ilerman and County Executive Derek Johnson said quarterly reports on delegated contracts will continue; Ilerman said the procurement team is revising public web pages and a "hub" of guidance to increase visibility and vendor outreach. Staff also said they were developing a draft sustainable‑procurement policy to integrate into the revised manual.

Supporters said the change reflects benchmarking with peer counties and the growing complexity of modern procurement. Supervisor Rodoni said he supported the approach but urged clear public reporting and a way to flag vendors whose practices do not align with county values. "There will be things we might want to flag for the assistant county executive," Ilerman replied.

The board approved the resolution unanimously. Staff said it will deliver department training in June and begin the phased rollout on July 1, with detailed procurement manual updates and potential technology procurement in 2027.
