How Seattle and King County are preparing for extreme heat this summer  科技资讯

By interviewing people who are unhoused, elderly or primary caregivers of small children, Seattle learned people didn’t feel comfortable taking advantage of public spaces. They expressed a desire for strategies to stay cool wherever they’re already spending time — in their own home or an encampment. 

Cooling centers will still be a big part of the response, given low access to air conditioning — only 44% of homes have it. But, Schmit says, “I think it's much more about helping people become cooler in their regular lives and a cooling center is not part of your regular life.” 

If cooling centers are available, people want them tailored to their needs and shared with people in similar situations. Parents, for instance, desire children’s play areas. Many people prefer outdoor offerings like sprinklers at Seattle Parks and Recreation sites, so the city is trying to make that part of its response, as well as other forms of entertainment, like movie nights. 

Many community centers that could be cooling centers lack cooling. 

“It’s not just a matter of adding an air conditioner when you have entire walls of south-facing windows,” Schmit says. Four of 26 community centers in Seattle have air conditioning, and in two of those facilities, just one room is equipped with it. Structural changes need to happen before many of the other community centers can even have air conditioning installed. Many community centers that do have cooling, like libraries, weren’t designed for the purpose of being emergency refuges.

Addressing the gaps

Gaps in information and services are big obstacles to improving the city and county’s response to extreme heat. 

For instance, there is no list of cooling centers that are guaranteed to be available during an emergency. Few cooling centers are available at night, when unhoused community members still need a safe space. Emergency alerts aren’t available in all the languages spoken in the county. And staffing for cooling centers is unstable. 

Government agencies are working on solutions for all of these issues, hoping for long-term climate-resilient strategies to cool the city before it gets too hot. The work won’t serve us in an imminent crisis, but will help down the line, not just with heat, but also to make the area more resilient to fire, smoke and other disasters.

“The goal is to strengthen short-term actions needed to cope with heat during a heat wave, while also looking at ways to adapt our built environments to be able to better handle heat,” said Lara Whitely Binder, King County’s climate preparedness program manager, during a recent press conference. The plan is expected to loop in the county’s tree-planting efforts, as well as increasing access to public green space, evaluating planning policies and codes, creating affordable opportunities to help people cool their homes and expanding access to money to help people make their homes more energy efficient. 

The county applied to and was selected for a Building Resilient Infrastructure Communities Grant from the Federal Emergency Management Agency to support the plan, but has not yet received the $120,737 attached to it. 

Sarah Brandt of 3 Million Trees, the county’s plan to boost and protect shade-providing tree canopy, says that project is already making progress. It had planted nearly 123,000 trees as of April 2022 since beginning planting in 2021, with a goal of planting 500,000 by the end of 2025. The project also has protected forests and natural areas equivalent to nearly 418,000 trees. The program doesn’t yet have a public-facing map of where it has planted trees. 

As part of Seattle’s efforts to electrify its buildings by 2035, the city is focusing on adding heat pumps to buildings that can provide cooling to communities during heat events. Kristin Brown with the city’s Office of Sustainability Environment says two community-serving facilities were recently equipped with heat pumps, and six libraries and community centers are set to be upgraded this year. 

King County Councilmember Girmay Zahilay recently put forward a motion asking for a clear operations plan showing how and where the county will activate cooling centers. It asked for associated costs, with a focus on vulnerable groups. 

Emergency operations staff are answering these questions, as well as expanding the network of cooling center providers — with a focus on unhoused residents and people in unincorporated areas. King County’s Office of Emergency Management recently developed an internal extreme heat playbook, outlining the roles and activities taken on by each partner agency, including guidance around opening and operating cooling centers. 

Zahilay hopes the plan he’s advocating for would add clarity to the issue. “What I'm looking for is something that looks like a map that shows a regional network of indoor spaces that can become activated immediately and stay open through the whole time we're having extreme weather,” he says. 

New this year, the King County Regional Homelessness Authority has taken charge of emergency response for unhoused neighbors. The agency’s Anne Martens says the authority is finalizing a severe weather response plan. “We're waiting on some final approvals. I would call this one of our major progress points on improving the crisis response system,” she says. 

The heat dome that wasn’t

The June 2022 temperature spikes luckily weren’t the testing ground they could have been for some of these new response policies. With shorter and less intense bouts of heat and lower overnight temperatures, the period of high heat at the end of June 2022 was far less damaging than the June 2021 heat dome. Public Health reported no heat-related deaths in the period between June 25 and 28, 2022, when temperatures reached 91 degrees Fahrenheit. There were also 49 emergency department visits for heat-related illness over the course of the month, compared with 624 visits in June 2021 over the same period. 

The King County Office of Emergency Management didn’t activate its emergency operations center this June but did review plans and processes for extreme heat. It  also discussed future plans with Public Health and the National Weather Service and reminded city and county agencies to stay vigilant to heat. Coincidentally, Seattle likely would have been in a good position to respond, as its emergency operations center was activated for the Pride parade, Hutton says. 

“We are likely to see additional, possibly more severe heat waves this summer, which will test the draft plans and new response strategies more fully than this past heat event,”  Hutton says.
