Measure U — a new $300M city bond

Levied on $31B of assessed value. The city advertises $22 per $100k average / $35 peak — on a base it projects will roughly double. On today's base the same bond is $50 average / $67 peak. Costs below are annual dollars per parcel — toggle the rate. Which rate is right? →

$22, $35, $50, $67 — which is it?

All four are the same $300M bond with the same debt service. They differ only in which year and which tax base you divide by. A rate per $100k is a quotient, not a price: the dollars to be raised are fixed; the rate moves with the base.

	City's projected base grows ~2.2× from future sales + new construction	Today's base $31B, the parcels that exist now
average year	$22 (the City's advertised figure)	$50
peak years (all three tranches outstanding)	$35 (the City's disclosed peak, from FY2040)	$67

The City's numbers are lower only because they assume owners who do not yet exist — future buyers reassessed to purchase price, and new construction — will carry roughly half of it. If the base grows as projected, a long-held owner's rate drifts down each year and newcomers make up the difference. If it does not, the rate is the right-hand column.
