Supervisors press administration on taxes, monthly delay costs and project scope

Supervisors at the joint finance‑SEED hearing repeatedly pressed the administration for detailed fiscal backup on the IJCC project, raising concerns about affordability and property tax impacts. One supervisor described the decision as "onerous" and flagged county five‑year plan deficits; another urged delay until state budget certainty before committing hundreds of millions in bonding authority.

Aaron Hertzberg and Jeremy Lucas outlined the county’s financing approach—phased guaranteed maximum price (GMP) packages, use of some cash to blunt property tax effects and an illustrative timeline for borrowing that would bring the bulk of the tax impact between 2030 and 2047. Supervisors asked for itemized support for administration claims, including the cited estimate that each month of delay would cost the county an additional $3–4 million. Hertzberg said the figure reflects modeling with construction partners but that a detailed line‑item breakdown was not presented in the hearing. The committee rejected a motion to lay the item over to December (2–5) and proceeded to votes on scope amendments and the final committee recommendation.
