Housing prices are soaring in Seattle thanks to the tech industry, but the boom comes with a consequence: A surge in homelessness marked by 400 unauthorized tent camps in parks, under bridges, on freeway medians and along busy sidewalks. The liberal city is trying to figure out what to do.

“I’ve got economically zero unemployment in my city, and I’ve got thousands of homeless people that actually are working and just can’t afford housing,” said Seattle City Councilman Mike O’Brien. “There’s nowhere for these folks to move to.”

That struggle is not Seattle’s alone. A homeless crisis is rocking the entire West Coast, pushing abject poverty into the open like never before.

Public health is at risk, several cities have declared states of emergency, and cities and counties are spending millions — in some cases billions — in a search for solutions.

San Diego now scrubs its sidewalks with bleach to counter a deadly hepatitis A outbreak. In Anaheim, 400 people sleep along a bike path in the shadow of Angel Stadium. Organizers in Portland lit incense at an outdoor food festival to cover up the stench of urine in a parking lot where vendors set up shop.

Homelessness is not new on the West Coast. But interviews with local officials and those who serve the homeless in California, Oregon and Washington — coupled with an Associated Press review of preliminary homeless data — confirm it’s getting worse.

People who were once able to get by, even if they suffered a setback, are now pushed to the streets because housing has become so expensive. All it takes is a prolonged illness, a lost job, a broken limb, a family crisis. What was once a blip in fortunes now seems a life sentence.

Among the findings:

—Official counts taken earlier this year in California, Oregon and Washington show 168,000 homeless people in the three states, according to an AP tally of every jurisdiction in those states that reports homeless numbers to the U.S. Department of Housing and Urban Development. That is 19,000 more than were counted in 2015, although the numbers may not be directly comparable because of factors ranging from the weather to new counting methods.

—Rising rents are the main culprit. The median one-bedroom apartment in the San Francisco Bay Area is more expensive than it is in the New York City metro area, for instance.

—Since 2015, at least 10 cities or municipal regions in California, Oregon and Washington have declared emergencies due to the rise of homelessness, a designation usually reserved for natural disasters.

The West Coast’s newly homeless are people who were able to survive on the margins — until those margins moved.

Nationally, homelessness has been trending down, partly because governments and nonprofit groups have gotten better at moving people into housing. That’s true in many West Coast cities, too, but the flow the other direction is even faster.

“So everybody who was just hanging on because they had cheap rent, they’re losing that … and they wind up outside,” said Margaret King, director of housing programs for the nonprofit DESC in Seattle. “It’s just exploded.”

All along the West Coast, local governments are scrambling for answers — and taxpayers are footing the bill.

Voters have approved more than $8 billion in spending since 2015 on affordable housing and other anti-homelessness programs, mostly as tax increases. Los Angeles voters, for example, approved $1.2 billion to build 10,000 units of affordable housing to address a homeless population that’s reached 34,000 people within city limits.

Jeremy Lemoine, an outreach case manager with REACH in Seattle, called the situation a refugee crisis.

“I don’t mean to sound hopeless,” he said. “I generate hope for a living for people — that there is a future for them — but we need to address it now.”
