Caltrans Removing Potentially Unsafe Trees From Roadside
Placeholder Image

Caltrans is identifying and marking dead and dying trees that could impact the safety of the traveling public along state highways. The effort is part of an on-going need to address over 102 million dead trees that have died due to drought and bark beetle infestation since 2010.

Caltrans is marking potentially hazardous trees along the roadway with orange paint and is seeking permission from private property owners to remove marked trees from their property. “Permission to Enter” forms will be mailed to affected property owners one to six months after trees are marked. Tree removal is provided at no cost because dead and dying trees near highways are potentially hazardous to the public.

“Safety is our number one priority, and we are working hard to remove any potential threats along our highways,” said Caltrans Director Malcolm Dougherty. “We’ve made significant progress already and will continue our efforts to ensure the roads stay safe and open for travel.”

In October 2015, Governor Brown recognized the magnitude of tree mortality and declared a State of Emergency. In the Governor’s Executive Order, he established the Tree Mortality Task Force where Caltrans has been working with partners like PG&E, county public works, CAL FIRE and the US Forest Service to coordinate tree removal. Collectively, the Tree Mortality Task Force members have removed or felled over 640,000 dead trees in high hazard areas. Caltrans has removed 107,000 hazardous trees near California highways and is expecting to remove 54,000 more by summer of 2018.

Counties most affected are: Amador, Calaveras, El Dorado, Fresno, Kern, Madera, Mariposa, Placer, Tulare, and Tuolumne. Trees in the Tahoe Basin have already been marked at locations along State Routes 28, 50, 89, and 267. Removal work will begin after the Labor Day Holiday.
