St. Helena City Council

Scott Diaz

Accountability you can check.

Since joining the Council, Scott has pressed for numbers residents can verify, rather than voting with the room. He works through the city's own audited data, source by source, so that decisions in St. Helena start from figures anyone can check.

Where Scott stands Get in touch

“Impressed us the most with his nuanced understanding of city finances and his objective, fact-based approach.”

Four things this campaign is about

Water Quality and Infrastructure Accountability

Manganese in our water, with residents paying for filters and bottled water. A Grand Jury report on water leadership. Residents deserve better than that, and it's Scott's top priority right now.

Fiscal Sustainability and Budget Oversight

Eleven years of audited General Fund data, traced back to the source instead of taken on summary.

Measure S: Where Scott Stands

Two separate questions: does the city need the revenue, and can we trust it to be spent well? Here's his answer to both.

City Government Efficiency

Part of the City Council that turned a $100,000 outside study into a department-level Interim Strategic Plan.

May 2026: Appointed to the St. Helena City Council.
August 2026: Part of the City Council that turned a $100,000 outside efficiency study into a department-level Interim Strategic Plan, accepted by the Council.
2026: Flagged accuracy and citation problems in the city's draft response to the Napa County Grand Jury report on water system leadership. The Council directed staff to make the corrections.
Before voting to place Measure S on the ballot: Reconciled competing claims about the General Fund using the city's audited financial data.

If something here doesn't add up, say so

This is a town of about 5,200 people. Questions about the budget, the water system, or anything else on the Council's agenda are welcome, and if you'd like to help with the campaign, there's a box for that on the contact form.
