This comment system is so crappy you can't cut and paste a reasonable sized document, so here goes in multiple posts the actual ballot measure as voted on.  Nowhere will you find an elephant reserve listed. There is no breach of contracts

QUESTION: Shall Zoo protect animal health and safety; conserve, recycle water; issue $125 million in general obligation bonds; require independent audits?

If the bonds are approved, they will be payable from taxes on property or property ownership that are not subject to the limits of Sections 11 and 11b, Article XI of the Oregon Constitution.

SUMMARY: Measure will:
Provide more humane care for animals: update four outdated and undersized enclosures with larger, more natural and safer spaces

Protect animal health and safety: modernize Zoo's substandard 45 year old animal clinic determined deficient by the American Zoo Association.
