City to test vertical drain option on Carden Street tree pits

Guelph, ON, October 28, 2015 – On Monday, November 2, City staff will carry out trials in three tree pits along Carden Street.

A preliminary investigation into the decline of the 11 red maple trees—removed in June—found that the tree roots were exposed to too much water because of improper drainage.

As a potential solution, City employees are cleaning out the tree pits, installing a vertical drain, and pouring water into the pit to see how it drains.

“If successful, vertical drains will be installed in the remaining eight tree pits and new trees will be planted. If the testing is not successful, other options will be explored,” says Timea Filer, urban forestry field technologist with the City.

The work, scheduled for 7 a.m. to minimize impacts on the downtown, is expected to take approximately five hours to complete.

“We hope to complete the work as quickly as possible, with the least disruption to downtown merchants, patrons, and parking,” adds Filer.
