Unstable trees removed at Point Defiance Park

Sep 30, 2009

A number of trees below the main picnic area in Point Defiance Park suffered extensive root system damage as a result of landslides and continuing soil erosion caused by last winter's storms. The unstable trees were individually evaluated and those in poor health were marked by the park district's urban forester for removal by a contracted tree care company.

"Their compromised root systems make these trees susceptible to fall once the rainy season starts, creating a potential hazard to park users and causing further damage to the slope", said Kathy Sutalo, Metro Parks Tacoma's urban forester.

A small number of trees were removed above the Washington State Ferry landing. The majority of the approximately 120, averaged between 3-8 inches thick and were located above the promenade, north of the Point Defiance Marina. Some of the wood was intentionally left on site to help block pedestrians from accessing unsafe areas.

Following the tree removal, work will be done to help stabilize the slope above the ferry landing and at the washout near the Rhododendron Garden on Five Mile Drive. A contractor will re-grade the failed areas of the slope, and large rocks and armoring materials will be placed to help shore-up some areas of the soil.

While full closures of Five Mile Drive are not expected, visitors may experience delays during October as crews stage and reposition equipment needed to complete the restoration work at the washout area.
