Our Current Project

It's 2014 and SDOT is carrying out a project at Boston that was proposed jointly by the QA Community Council and PPQA. The project originally called for replacing sidewalk uplifted by tree roots, enlarging the three tree pits, and repairing crumbling curbs.

When the sidewalk was removed, SDOT determined, through extensive effort involving several arborists, that the three ash trees would need to be removed to ensure public safety, longevity of trees at this location, and preservation of the new sidewalk.

Preparing for Tree Removal
David Allen of SDOT elaborated, “During a sidewalk repair project, SDOT removes the old sidewalk, examines the tree roots, and evaluates tree health and structure.  Root pruning is routinely performed as part of this process as a means to preserve both tree and sidewalk.  In some cases, the amount of root pruning necessary to construct a new sidewalk exceeds the threshold that could sustain a healthy tree."

“In this case, the westernmost tree and easternmost tree required extensive root pruning, which would have severely affected their health, jeopardized their structural stability and caused safety risks.  Therefore, SDOT determined the best plan is to replace them."

“The center tree (the smallest one) did not require such extensive root pruning, so it could have been preserved for the time being.   However, all three trees were Ash, which adapt poorly to --and often decline after -- root pruning.  Given that this smaller tree was impacted by root loss, the decision was made to replace all three trees to support the community’s desire for uniformity along the block, while adding diversity to the street tree population.    There is the potential future threat of Emerald Ash Borer finding its way to Seattle, and SDOT weighs that risk when considering opportunities to replace Ash trees in the street tree population.  The replacement Ginkgo trees are extremely insect and disease resistant and have demonstrated excellent health and vigor in other business districts where we have recently planted them.”

As a matter of fact, if you look directly east across QA Ave, the trees you see along the south side of Boston are Ginkgos. We’re disappointed that the lovely mature ash trees did not survive the necessary root pruning.  We look forward to the Ginkgos, with their beautiful fan-shaped leaves, eventually creating a cooling shady canopy.
