Parametrix has a 10-year contract to provide architectural and engineering services to support the EPA’s mission to recover, remediate, and restore chemically contaminated Superfund and brownfields sites throughout the Pacific Northwest and across the United States. Projects have ranged from major mine investigations and remediation to industrial facility monitoring and remediation for sites with complex organics and metals contamination. Best practices have been applied to secure environmentally and economically sound solutions to legacy environmental damages.

The 2-acre sediment cap was conducted as a pilot study. Several years of monitoring data indicates that the sediment cap is performing as expected and aquatic species are flourishing. In addition, we designed and secured required regulatory approvals to stabilize more than 1 mile of shoreline, install 20 acres of nearshore sediment cap, and dredge the Tacoma Yacht Club basin; and remove three large piers that covered 1.6 acres of marine habitat.
