Proposition 435: What Yuma County’s $6.2 Million Spending Proposal Actually Does

Yuma County voters will decide Nov. 3 whether to permanently add $6.2 million to the historic base used to calculate the County’s Annual Expenditure Limitation (AEL). The County describes that as about a 65% increase to its base, beginning in fiscal year 2027-28. The proposal changes a formula’s starting point. It does not appropriate $6.2 million or automatically add that amount to the County’s annual spending.

The Board of Supervisors approved Resolution 2026-22 as presented on May 18, referring the measure to voters. On Oct. 5, the Board received an informational presentation; the agenda said no action was required. Yuma County’s election information lists Proposition 435 as a County measure, distinct from City of Yuma Propositions 436 and 437.

What the expenditure base does

Arizona’s Constitution ties each county’s annual spending limit to actual payments of local revenues in fiscal year 1979-80. The historical amount is the base, not the County’s current budget or the sum it can spend today. The Arizona Economic Estimates Commission adjusts the base for voter-approved permanent changes, population growth and inflation to calculate each year’s limit. The Arizona Auditor General’s county guidance describes that formula and how exclusions apply.

The AEL applies to covered spending from local revenues, not every dollar in a government’s total budget. The Auditor General says federal grants and certain state revenues are excluded from the constitutional definition of local revenue. Yuma County also lists debt service, grant-funded projects, some capital improvements and investment earnings as exempt.

For fiscal year 2026, the County lists a $552 million all-funds budget and a $121 million AEL. The $431 million difference between those totals does not establish an overrun: the AEL does not count all funds and all spending. The two figures describe different scopes, so the gap should not be read as $431 million the County can freely redirect or as the size of Proposition 435.

Why the County wants the change

The County says the formula has not kept pace with its operating conditions. It reports that state-collected sales tax shared with the County grew by an average 6.4% per year over the past decade, while the AEL rose by an average 2.6% per year. The County also cites the effect of 2020 Census population adjustments, as well as modern service, labor, infrastructure and regulatory costs that the formula does not directly measure. These are the County’s stated rationale and figures.County’s explanation of the AEL

The County says it has used efficiencies and operating adjustments to work within the current limit and argues more capacity is needed to maintain services and investment. An Oct. 5 presentation to the Board described Proposition 435 as a $6.2 million, roughly 65% increase to the historical base. That percentage is not a proposed 65% increase to the current annual limit, the total County budget or every department’s funding.

What a Yes or No vote would mean

A Yes vote would authorize the permanent $6.2 million base adjustment. The Commission would use the revised base in calculating future County expenditure limits, starting in fiscal year 2027-28. Because the adjustment is permanent, it would carry into later calculations. A higher legal limit would create room to spend more covered local revenue if available; it would not require the Board to spend up to the limit.

Any spending would still need available revenue and approval through the County’s annual budget process. The Board would have to decide whether and how much to appropriate, and for which purposes. The proposition itself does not direct money to roads, law enforcement or another service.

A No vote would leave the existing base in place, with the regular population and inflation adjustments continuing. The County says this could make service needs harder to meet and may limit its ability to spend some revenue it is allowed to collect. That is the County’s forecast. The County has not identified a list of specific service cuts that would follow a No vote.

Taxes, services and the City’s separate measure

Proposition 435 does not increase property or sales taxes, create fees or generate revenue, the County says. It concerns spending authority under the AEL. The County says roads, criminal justice, law enforcement, emergency response, public works, health services, facilities management and general government include costs that count toward the limit. Those broad categories identify services exposed to the cap; they do not establish which programs would gain or lose money under either outcome.

Yuma voters will also see City Proposition 436, which proposes a separate $30 million permanent adjustment to the City of Yuma’s base. It applies only to the City, while Proposition 435 applies to the County. Neither creates revenue, and neither determines the other’s spending limit. Yuma Informed’s Proposition 436 explainer covers the City measure.

What the public records do not show

The County’s published explanation gives the requested base change and its existing fiscal-year 2026 budget and limit figures, but I did not find a year-by-year estimate of how much Proposition 435 would raise future annual limits, an estimate of added spending, or a service-by-service spending plan. The measure would increase the legal ceiling, not the actual amount appropriated.

There is a supported case for approval in the County’s argument that the current formula constrains its ability to match spending authority to local revenue and current service demands. The case for rejecting it is to retain the existing spending restraint rather than permanently raise the base. The County invited arguments for and against by July 10, but the records reviewed for this article did not include a completed County voter pamphlet or an independently prepared fiscal analysis. The County’s predictions about future service pressure should therefore be weighed as its claims, not as a documented schedule of cuts or guaranteed new spending.
