Heat waves are becoming more frequent and intense across the U.S. Two of the country's hottest cities, Phoenix and Dallas, are seeking solutions to protect...
“It makes sense that Phoenix would be on the forefront of really trying to deploy these strategies in a citywide effort,” Dahl said.which outlines eight primary areas where the city can prepare for and address the impacts of climate change. Those include strengthening the city’s transportation infrastructure, enhancing green spaces and making buildings more energy-efficient.
Unsheltered people are about 200 times more likely to die from heat-related causes compared to sheltered people, Hondula said. The team has interacted with about 3,300 people since it started in May. Rojas said out of the thousands of individuals the team talked with this summer, he knows of less than 10 that definitely found stable housing in either rehab or a shelter. Some of the people they meet are distrustful of the city’s logo and resources, and Hondula said they have legitimate reasons to be. With only a single three- to four-person team going into the community four times a week, it’s impossible to reach every community in need.
“We have air conditioning at home, and we go into our air-conditioned car,” she said. “But there are a lot of people who are unsheltered and unhoused, who live in mobile homes, elderly people who maybe don’t have the funds to run their air conditioning all the time … There are a lot of vulnerable people, and I think that a lot can be done to prevent heat-related illnesses and death.”
The product, called CoolSeal, coats the top of asphalt surfaces. It’s not paint – it’s a safe, nontoxic seal coat. CoolSeal makes asphalt more reflective. That way, it absorbs less direct sunlight during the day, and at night, there’s less solar energy released back into the air to heat up neighborhoods.
However, Middel said she is hopeful CoolSeal will prevent pavement from degrading as quickly, adding to its value. Nicewander said the department hopes to get a cool pavement pilot project started within the next year and a half, potentially in a neighborhood that lacks trees and shade to maximize the benefit. She would like the city to integrate cool pavement treatment into its existing pavement preservation program — applying it to neighborhood roads that need repaving anyway, but aren’t in total disrepair.
Martens said one of the biggest hurdles to urban tree-planting is cities weren’t constructed with trees in mind. Phoenix, she said, is focusing on “low-hanging fruit”: areas where there aren’t major power lines or size constraints limiting where they can plant.“Soon, we’re going to have to have conversations about reducing streets and expanding areas throughout sidewalks, things like that,” she said.
