Stress-Testing the Sales Tax Case: What If the City's Assumptions Are Wrong?

The $14 million annual revenue projection anchoring Santee's sales tax argument rests on an assumption of stable consumer spending at current levels — but Santee does not operate as an isolated economic island. Raising the local rate by a full percentage point, to 8.75 percent, would place Santee meaningfully above the rate in neighboring El Cajon and other East County cities. Large discretionary purchases — vehicles, major appliances, significant retail transactions — are sensitive to tax rate differentials, and buyers have an incentive to complete those transactions across a short drive. If current spending levels shift in response to the rate increase, the $14 million projection becomes optimistic.

The spending-side risk is arguably more fundamental. The city's accountability argument relies on political commitment rather than legal obligation: advisory committees and annual expenditure reports are procedural mechanisms, not binding constraints. Santee will hold council elections in 2026, 2028, 2030, and beyond. A future council facing a pension obligation shortfall, a significant legal judgment, or an emergency expenditure retains full legal authority to direct general tax revenue toward those needs rather than toward the infrastructure backlog the current council is promising to address. Ten years is a long time to hold a political promise.

The backlog arithmetic compounds the concern. At $14 million annually over ten years, the measure would generate $140 million in new revenue — less than half the $322 million backlog, assuming the backlog does not grow. Infrastructure backlogs historically do grow: deferred maintenance compounds, and systems continue to age. The tax could produce substantial revenue and still leave Santee in a structurally similar fiscal position when it sunsets in 2036.

City leaders offer a cogent counter: doing nothing guarantees the backlog grows, and a general tax is the only instrument available that can clear a simple majority at the ballot box. A legally binding special tax requires two-thirds of voters — a significantly higher threshold. The honest choice, they argue, is between an imperfect general tax and continued deferral. Voters watching for early warning signs after a potential November passage should monitor whether independent infrastructure audits are commissioned and made public, and whether annual expenditure reports show sales tax revenue flowing to the specific backlog items named in the original pitch — or migrating toward general fund needs instead. Intellectual honesty, as the case was framed, runs in both directions: if the backlog measurably shrinks and accountability mechanisms hold, critics of the measure would owe that outcome an honest accounting too.
