So, you found a ballot in your mailbox.

Don’t panic. We’re still a whole year away from the day we get to boot Trump out of the White House and elect at least one new commissioner to Portland’s city council. Those races have absolutely nothing to do with this year’s ballot, or the upcoming November 5 election.

And yet! Like any election in our imperfect democracy, the choices being made on November 5 are important. The measures Portlanders will vote on this year are remarkably uncontroversial (unless you’re the Oregonian editorial board), but they still threaten to impact your tax dollars, drinking water, schools, and favorite wild places. Here’s a rundown on what’s on your ballot:

Portland Public Schools Levy Renewal

In 2014, Portland voters passed a levy, charging homeowners $1.99 for every $1,000 of their home’s assessed value. That means if a home is worth $400,000—slightly lower than the current median home price for a Portland-area home, which in September was $410,000—owners pay $796 annually. These funds cover the salaries for the tireless teachers at Portland Public Schools (PPS). Since 2014, the levy has employed an annual average of 825 teachers. This ballot measure asks Portlanders to renew the PPS levy for another five years.

Metro Bonds

Behold, the only slightly contentious measure on the ballot: An ask to redirect property taxes to fund conservation work on public lands owned by Metro, the regional government agency for Multnomah, Clackamas, and Washington counties. The bond charges homeowners 19 cents per $1,000 of their home’s value (if a home is worth $400,000, that’s an annual cost of $76) to continue Metro’s work creating native fish habitat in local rivers, restoring wetlands, maintaining trails and parks, and continuing a program that helps communities restore wild spaces in their neighborhoods.

This bond won’t necessarily increase taxes, as it’s replacing a Metro bond that’s about to expire. Yet extending the duration of apparently any tax is something local libertarian organizations refuse to get behind: Both the Cascade Policy Institute and the Taxpayer Association of Oregon have come out in opposition to the bond, as has the Oregonian Editorial Board, which says the measure is too vague.

Bull Run Watershed Protection

The City of Portland is currently required by the state to protect the Bull Run Watershed—the city’s primary source of drinking water—from pollution caused by public use. That state mandate, however, is set to expire in 2027. This measure would enshrine Portland’s requirement to protect the Bull Run in the city charter, making it much harder to undo. The alternative is putting this off until 2028, when you’re showering in sewage water.

Emergency Mutual Aid Agreement

When that earthquake we’re all living in fear of actually hits, all of Portland’s drinking water could be contaminated with toxic sludge. Overnight, those smart jerks who stocked up on filtration systems and water jugs will become our Water Overlords, and we, the dehydrated masses, will have no choice but to initiate the Great Water War. Or we could pass a ballot measure that will ensure that, in times of crisis, Portland is able to receive emergency water from other cities. The choice is yours.
