SOUTH NASHVILLE, Tenn. (WTVF) — During these extreme heatwaves, not all neighborhoods will experience the heat the same way.
Dense city centers are almost always hotter than grassy, tree-covered suburban areas. In Nashville, Madison, North Nashville, and South Nashville will have hotter surface temperatures along with downtown, according to the Cumberland River Compact.
I met Jason Sprouls who is part of the Cumberland River Compact's urban forestry team. We met at a green space at 1800 Nolensville Pike.
"Here in our downtown corridor versus some of the peripheral parts of Davidson County it can be six to eight degrees hotter — depending on the part — just because of the [lack of] trees," said Jason Sprouls.
We met up with Sprouls after I searched for what changes could be made to cool off our communities.
The park at the corner of Nolensville Pike and Moore Avenue was an abandoned parking lot until 2021. Then, 18,000 sq. ft. of asphalt was dug up by volunteers, and it was covered with native plants.
Sprouls explains what happens when the sun hits an impervious surface of that size.
"If it hits a green surface it's going to get absorbed into the chlorophyll of the plant versus if it hits a black surface it's going to re-radiate and create heat," Sprouls said.
On an August day in 2022, a group collected thousands of temperature points in Nashville. You can see on the map below which areas were hottest by day's end. The deeper the red the hotter the area had gotten.

Right now, the Compact is looking for any unused surface lot in the county they could depave like the Nolensville Pike lot.
"Trees can reduce surface asphalt temps by 30 degrees Fahrenheit, and vehicular cabin temps by up to 50 degrees," he said.
People who want to suggest a lot can reach out directly to the Cumberland River Compact. If you do not own a lot that could be repurposed, individual trees are available for free through Root Nashville which is the citywide campaign, led by the Compact and Metro Nashville to plant 500,000 trees in the county by 2050

It’s a sad reality that area animal shelters and non-profit rescue organizations face constant overcrowding -- with so many dogs, cats and other animals waiting for a forever home. Jason Lamb reports here that Metro leaders are working with those groups – including Critter Cavalry – to find solutions. I’ve fostered a dog from Critter Cavalry, so I understand the need is great. And I found my pup Domino through another local group, Proverbs Animal Rescue. Ultimately, it starts with all of us. Getting more dogs and cats spayed or neutered can help control the pet population – and ease the burden.
