Spending comparison pending

A spending-by-function comparison is not shown yet because the FY 2026-27 Recommended Budget extraction has not produced a matching all-funds requirements-by-major-function table.

The source does include account-class rows, but CivicCause will not relabel account classes as function priorities. That spending view needs a separate source/read-side decision.

Methodology and caveats

The comparison uses FY 2025-26 Adopted Budget as the baseline and FY 2026-27 May Recommended Budget as the current recommended/proposed layer.

FY 2026-27 Revised and source Change columns are not used as the adopted-vs-recommended comparison. They remain validation context only.

Limited to source-grounded County Summary / All Funds rows. FY 2026-27 Revised and source Change columns are retained only for validation.
Limited to source-grounded County Summary / All Funds source categories. No spending/function comparison is included.
