In redeveloping a site adjacent to the Seattle Center grounds as the location of their new headquarters campus, the Bill and Melinda Gates Foundation negotiated a property transfer that obligated the Seattle Center to address groundwater remediation of the former vehicle maintenance site. Helping the Seattle Center meet the groundwater remediation obligations, Aspect led the groundwater assessment and remediation efforts with an emphasis on integrating cleanup into the redevelopment plans, designing a full-scale air sparging (AS) and soil vapor extraction (SVE) remediation system for phased installation. The first phase of AS/SVE was successfully installed in the pre-construction footprint and operated while the campus design and permitting process was completed. The second phase of the remedial system was installed within the active excavation footprint. By integrating the remediation system into the campus design, the second phase of the remedial action was designed to continue once the structure was completed.
Seattle Art Museum (SAM) with the City of Seattle formed a public development authority to obtain remedial action grant funding for the cleanup and redevelopment of an 8-acre former fuel facility on the downtown Seattle waterfront for use as a park. As environmental lead, Aspect helped the development team incorporate the requirements of the Cleanup Action Plan (CAP) into the park design, integrating remedial elements into the infrastructure requirements. Many of the larger costs for park construction were covered as remediation expenses under remedial action match funding, providing substantial cost savings for the redevelopment project.
