Tree Mortality Update

Drought and bark beetle infestation has killed thousands of Twain Harte's majestic pine trees over the last two years. As we mourn the change of our beautiful landscape, we also become aware of the potential dangers that tree mortality brings to our community. Many dead trees have already been removed, but the number of dead trees seems to outpace removal. It seems like a problem too large to tackle, but our residents and local agencies are banding together to help keep our community safe.

What is our District Doing?

The District received California Disaster Assistance Act (CDAA) funding to pay for 75% of the costs to remove dead and dying trees that threaten at-risk water and sewer infrastructure.  We are pleased to report that we removed 433 trees in the District, protecting our facilities and the community.

We are currently undertaking our second project to remove approximately 35 additional  dead and dying trees that threaten our facilities.  That project should be completed by the end of December 2018.

What are Other Agencies Doing?

Pacific Gas & Electric (PG&E)

PG&E has removed more than 80,000 trees in Tuolumne County and continues to mark and remove trees that threaten powerlines at a fast rate.  PG&E has also implemented a debris management program to help remove eligible logs after falling. It is important to note that log removal may occur up to four months after trees are felled. Contact PG&E at 1-800-743-5000 if you believe you have dead tress that threaten powerlines.

Tuolumne County

Tuolumne County is undertaking CDAA funded projects all over the County to remove dead and dying trees that threaten County roads and other County facilities, including removal projects along Twain Harte Drive and North Tuolumne Road.  They have sent right-of-entry forms out to many residents in Twain Harte and will soon begin a project that will remove approximately 380 trees along County roadways throughout town.

TUD is undertaking CDAA funded projects to remove dead and dying trees that threaten their high risk water and sewer facilities. They have already completed tree removal projects near high risk tanks and along the ditches in Twain Harte and are working toward removing around 1,700 trees along the Eureka Ditch.  


Caltrans recently completed a hazard tree removal project that removed approximately 9,000 trees along the Highway 108 corridor.  They plan to undertake a second hazard tree removal project along Highway 108 in early 2018.
