Big Tree Fall Hard in Ashton Heights

(Updated at 5:15 p.m.) A downed tree in the Ashton Heights neighborhood is leading to a call to the county ombudsman’s office.

The big tree, said to be more than a century old, fell last night near the intersection of N. Lincoln Street and 5th Street N., knocking out power to the area.

The neighborhood listserv is now abuzz with talk of what might have caused the old tree to fall during calm weather. Paving work on the street, residents are speculating, may have had something to do with it.

“A massive road repaving project brought in heavily vibrating equipment — many thought unnecessarily vibrating — which, according to our neighborhood listserv buzz, may have contributed to the tree’s fall, given very wet soil conditions,” a resident told us. “I lack professional credentials to shed light on that one way or another.”

Whether rooted in fact or not, residents are not content to leave the issue alone. They’re barking up the tree of the county ombudsman, according to a listserv email.

“Scott Sklar is contacting the county ombudsman about this problem today and complaining on behalf of Ashton Heights,” the email says. “The tree was 125 years old. Very sad.”

Sklar, president of the Ashton Heights Civic Association, said residents felt as if there was an “earthquake” when the heavy equipment was in use. One resident even reported that her morning cup of coffee rolled off the kitchen counter and broke as a result of the pervasive vibrations.

There’s “no question” about what caused the tree to fall, he said.

“The County contractors are using percussion rollers to compress the road under-bed — which uses intense weight and sound rather than the usual heavy roller compression approach,” he told ARLnow.com. ” There is no question in my mind, that this new approach is what caused this old tree to fall after the heavy rain we just had.”

“Use of percussion rollers should not be used in areas where there are large trees and old homes (pre-2000),” Sklar said. “Manufacturer’s warnings on percussion rollers explicitly state they should not be used near large trees or old buildings

Meghan McMahon, spokeswoman for the Arlington Dept. of Environmental Services, said in a statement that the county is “reviewing the matter.”

DES crews have been performing roadbed reclamation and paving on Lincoln Street over the past week. The roadbed reclamation process, which was completed on June 30, is more disruptive than normal paving or patching. This process uses a machine that churns and mixes the base of the road at a deeper level so more vibrations and disturbance may occur. This process is specifically used for underbuilt, lower volume roads like Lincoln Street. Our paving contractors use vibratory rollers and other heavy machinery during the roadbed reclamation process. These rollers are also used on every street during maintenance and repaving. Rollers are commonly used to gain better compaction in asphalt construction. Yesterday’s work on Lincoln Street was repaving.

We have used these processes for several years in this neighborhood and several others like it that have older trees and houses. This is the first we have heard of such impacts from this type of work. We are reviewing the matter to determine what caused the tree to fall.

As seen in the photos above, some paving equipment was underneath the tree when it fell.

“Two County vehicles were enclosed by the tree canopy when it fell, but neither were impacted or damaged,” said McMahon. “The storm drain was damaged, but we have already put in a work order to fix this. It will be prioritized based on other work we have and safety.”
