10/4 Update: Message from our Landscape Supervisor regarding tree removal:

As you may already know, we will be removing the tree in the courtyard beginning Wednesday to allow for a drainage project that will prevent water from dripping into the basement of Klamath and onto the atomic resolution microscope in the Nazin Lab.

Through our diagnosis of the causes and treatment of this leak, we have concluded that the roots of the wisteria pose too much of an ongoing structural risk to the waterproofing of the basement, and we plan to remove the remaining wisteria.

We are unhappy to be removing the gorgeous catalpa tree which is so uniquely shaped and adds so much to the feel of the courtyard, and removing the wisteria will further reduce foliage and its softening effects.  Unfortunately, we have not been able to find an alternative solution that protects the microscope and its valuable research.

After the drainage project is complete, the lawn will be restored, and we will evaluate opportunities for a new tree to be planted in the courtyard.

Following the removal of the tree this week, work will begin on the installation of underground drainage and vine removal.  We do not yet have a firm timeline of the latter events, but we are moving forward so as to lessen the chance that winter rains will continue to cause problems in the basement.

If you have any questions about removal of the tree and vine, or about potential impacts to owl roosting opportunities, I will be happy to answer. The catalpa tree being removed was posted for three weeks, two weeks being our typical minimum posting time.  Please let me know if you would like to discuss overall concerns about university tree management practices.

For questions about the structural aspects of addressing the basement leak, I will refer to Bruce Budzik (copied here), Zone B Maintenance Manager.

Thank you,

Phil Carroll, Landscape Supervisor



Campus Community,

On October 4, 2017,  from 6:00 am – 12:00 (noon) there will be landscape activities in between Willamette, Klamath, Streisinger, and Huesitis.  The primary effects of this work will be intermittent noise from power equipment and traffic from hauling away debris.  Please expect intermittent access closures and some noise during the duration of this work.  Crews will have areas well marked for the safety of the campus community.

For questions or concerns, please contact CPFM Facilities Services Becket DeChant 541-346-8936
