Heidelberg Materials is starting a cleanup project to address damage caused by decades of quarry operations near Cupertino. The project is mandated by a 2011 lawsuit settlement and aims to restore 3.5 miles of Permanente Creek by 2030, removing toxic sediment and restoring the local environment. Activities include planting native plants, creating trout pools, and stabilizing eroded slopes. Initial cost estimates were around $10 million in 2013, but actual expenses are expected to be significantly higher. Community members express relief that the restoration is finally occurring.
The restoration will remove tons of sediment that include selenium, nickel and other toxic metals that washed out of the quarry over the years.
Under the settlement, the company is required to restore 3.5 miles of the creek by 2030.
Workers also will plant native vegetation, build pools for trout, and stabilize slopes.
It's definitely taken a long time. But it's going to bring the creek back to a habitat that can support fish like steelhead and trout.
