After 15 years, the largest privately conducted and privately funded cleanup on the Willamette River is complete.
First to be cleaned up were human health hotspots and ecological hotspots from the area above the river. This summer complications to the remediation effort arose, involving permitting and working within “fish windows” to protect habitats. In some areas contaminants were excavated and the bank was graded to a gentler slope. In areas where contaminants were not removed, the ground was capped with sand and heavy rock was added to protect the sand cap from erosion. A different kind of cap made of fabric that filters contaminants was placed in other areas.
Landscaping and some remediation will continue through next year, after which Zidell will be responsible for maintaining involvement in development over the next five years, to ensure that remaining contaminants are not disturbed. In total, the project includes:
Some 15,000 newly planted shrubs and 212 new trees.
