Today, the Port of Portland moves forward with the second phase of work on the PDX Tree Obstruction Removal Project in the economy parking lot at Portland International Airport. The project began last fall with the removal of approximately 400 cottonwood trees that were beginning to encroach on federally-regulated airspace surrounding PDX’s north runway.
The site will ultimately be replanted with lower-growing native trees and shrubs. The project is being executed in several phases to minimize site disturbance during wet weather months and to maximize the survivability of the new plants. The second phase, starting this week, will consist of removing stumps that were left on-site following the tree removal activity last September. Travelers and motorists should expect to see equipment removing the stumps for up to a month.
Many of the stumps will be recovered and repurposed for habitat restoration projects. Some stumps are being given to the City of Portland and the Fairview Lake Property Owners Association. Others will be used by the Port on its own mitigation sites including projects at Troutdale Reynolds Industrial Park and Buffalo Slough. The stumps are used to create habitat enhancements such as basking areas for turtle species and to simulate naturally-occurring large, woody debris features in waterways.
When the site is replanted next fall, the trees will be replaced with more than 23,000 native shrub and small tree species such as vine maple, Oregon grape, red-flowering currant and native roses and willow. They will be planted around existing, lower-growing species of trees and shrubs that were left untouched. The images below show an artist’s rendering of what the site will likely look like once the replanting has occurred.
