How to use this

Utility pages stay canonical

Northern California benefits from a metro support layer because the utility surface ranges from city-run approved lists to large district programs, Aqua Backflow reporting, Tokay test entry, and reminder-driven municipal programs like Santa Rosa. This page groups those local routes while still forcing users back down into the exact authority page.

Use this metro page to compare nearby utility workflows and public provider options, then drop into the exact utility page before acting on a compliance step.
