This property has a documented history as a public works and maintenance facility going back to 1944. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The City of Seattle Parks Department operated a vehicle maintenance and fueling complex at this Roy Street property, with engineering drawings documenting fuel system installations dating to 1944. The fueling system included underground storage tanks for both unleaded gasoline and diesel, positioned adjacent to the service shop building. Cleanup activities have included interim excavation and removal of the USTs and contaminated soil, removal and disposal of stored fuel and tank contents, and multi-year groundwater monitoring. Multiple remediation alternatives — air sparging, bioventing, microbiological injection, and thermal desorption — have been evaluated as options for addressing residual soil and groundwater contamination. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
Why Historical Insurance Policies May Be Accessible
Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.
The fueling infrastructure at this municipal maintenance yard traces to at least 1944, placing more than four decades of petroleum operations squarely within the era when occurrence-based CGL policies written for the City's operational exposures carried no effective pollution exclusion. The interim UST removals, soil excavation, and years of groundwater monitoring already recorded represent a documented cost trail tied directly to those pre-1986 operations at this facility. Because remediation alternatives are still under evaluation and groundwater monitoring remains active, historical carriers who insured the City of Seattle's parks operations during that pre-1986 window may be obligated not only to recover the costs already incurred but also to fund the ongoing and future cleanup work still ahead.
