Yuma Propositions 436 & 437
A plain-English evidence guide to City of Yuma Propositions 436 and 437 on the November 3, 2026 ballot. Proposition 436 concerns a permanent adjustment to the City's expenditure base. Proposition 437 concerns how nomination-petition signature requirements for City elected office are calculated.
Detailed overview
These are two separate decisions: Proposition 436 concerns spending authority; Proposition 437 concerns candidate nomination signatures. Appearing together on the ballot does not combine their legal effects.
Proposition 436 proposes a permanent $30 million adjustment to the historical expenditure base used to calculate the City's annual spending limit. It is not a $30 million cash receipt or a fixed $30 million annual allowance. The City says the measure itself creates no new tax or fee or additional revenue, and that the revised base would apply beginning in Fiscal Year 2028 if voters approve it. That does not promise a particular service outcome or bind future separate fiscal decisions. City explanation; O2026-015 staff report.
Proposition 437 would use valid ballots cast in the preceding primary municipal election instead of the preceding general municipal election to calculate nomination-petition signatures. The proposed amendment keeps the 3%–5% range. Future numerical requirements depend on the relevant ballot count; the measure does not guarantee a particular reduction. Proposed amendment, page 1, Section 2.
Start with the combined explainer, then read the expenditure-base explanation and the candidate-signature explanation. The City lists both measures for the scheduled November 3, 2026 General/Special Election. This guide explains the mechanisms and evidence limits without recommending a vote.

- VerifiedIf approved, Proposition 436 would permanently add $30 million to Yuma’s expenditure base used to calculate the AEL.
The proposal changes the calculation base, not the amount of cash held by the City.
- VerifiedIf approved, the revised Proposition 436 base would begin affecting Yuma’s expenditure limitation in Fiscal Year 2028.
The election date and implementation fiscal year are different milestones.
- VerifiedProposition 437 would change the signature-calculation denominator from the preceding general municipal election to the preceding primary municipal election.
The election supplying the valid-ballot count changes.
- VerifiedProposition 437 would leave the 3%–5% nomination-signature range unchanged.
Both percentage endpoints remain; the election basis changes.
- VerifiedThe City states that Proposition 436 itself creates no new tax or fee, increases no existing tax rate, and authorizes no additional revenue.
This describes the measure itself, not every future City fiscal decision.
- VerifiedThe City’s documented 2026 candidate requirement was a minimum of 998 and maximum of 1,664 valid nomination signatures.
These are the 2026 requirements, not a projection under Proposition 437.
