As Democratic voters moved to retake the House of Representatives and key gubernatorial seats, a series of local architecture-, urbanism-, and climate-related initiatives saw mixed results in western states.

Aside from being a referendum on the divisive governance style of President Donald Trump, the midterm election brought with it fierce debates over contentious issues like expanding rent control and funding supportive housing in California, taxing carbon emissions in Washington State, and boosting renewable energy generation in Arizona and Nevada.

Here’s a state-by-state breakdown of some of the major initiatives and their outcomes.

Arizona:

Proposition 127: An initiative to require electric utilities to use renewable energy for 50 percent of their power generation by 2035 failed in the state. The battle over Proposition 127 saw the highest amount of political spending in the state this year, with the state’s main electrical utility, Arizona Public Service, pouring over $30.3 million into a political action committee dedicated to fighting the measure.

California:

Proposition C: San Francisco’s supportive housing ordinance was overwhelmingly supported by the city’s voters. The initiative will raise $300 million per year for supportive housing and services from a modest tax levied on companies in the city that gross over $50 million annually in revenue. The measure is similar to the so-called “head tax” in Seattle that was passed and quickly repealed earlier this year.

Proposition 1: An initiative to approve $4 billion in “housing-related programs, loans, grants, and projects and housing loans for veterans” in the state gained wide approval.

Proposition 2: An initiative to dedicate $2 billion from the state’s 2004 “millionaire’s tax” toward providing “homelessness prevention housing for persons in need of mental health services“ was approved.

Proposition 4: An initiative authorizing $1.5 billion in bonds for the “construction, expansion, renovation, and equipping of children’s hospitals in California” was approved.

Proposition 6: Voters in the state defeated a Republican-led effort to repeal a recently-passed gas tax increase. The recent increase is helping to fund bridge and road repairs while also providing new—and much-needed—mass transit funding for the state’s growing public transportation systems.

Proposition 10: A state-wide effort to repeal the controversial Costa-Hawkins law that limits how municipalities can institute rent control was soundly defeated. Rather than instituting rent control statewide, the measure would have allowed municipalities the flexibility to set their own policies. Tenants’ rights and anti-displacement advocates saw the effort as providing a lifeline for their constituencies; ultimately, the $76 million raised by real estate and Wall Street interests against the measure was too much for grassroots voters to overcome.

Colorado:

Proposition 112: Voters in the Centennial State chose to reject a ballot initiative that would have increased oil and gas drilling setbacks from homes, businesses, and waterways. Resistance to the measure was no match for heavy spending by the Colorado Oil and Gas Association, the proposition’s main opponent. With controversial hydraulic fracturing rising to new highs in the state and an increasingly bleak outlook for climate change-related disasters around the world, Colorado’s pro-environment movement has been dealt a powerful rebuke.

Nevada:

State Question No. 6: Voters in Nevada approved a measure that would require state utilities to generate 50 percent of their electricity from renewable sources by 2030. In order for the measure to become law, however, it will need to survive a second vote in 2020.

Washington State:

Measure 1631: Washington state residents largely rejected a measure that would have imposed a first-in-the-nation tax on carbon emissions. The initiative performed well in liberal King County—home to Seattle—but lost pretty much everywhere else in the state.

Measure 940: Washington state residents approved a measure that would require law enforcement officials to receive “de-escalation” and mental health training as well as provide first aid under certain circumstances. The initiative would also require authorities to conduct an investigation after a deadly use of force by a member of law enforcement in order to verify that such force meets a “good faith” test.
