This property has a documented history as a public works and maintenance facility going back to 1925. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property served as a maintenance facility for the King County Department of Transportation, Roads Services Division from the mid-1920s through the mid-1960s, with operations that included vehicle fueling and maintenance, machine shop fabrication, and materials storage. Cleanup under the Voluntary Cleanup Program included the excavation and off-site disposal of more than 10,000 cubic yards of contaminated material — tar, underground storage tanks, and associated debris — followed by a two-year monitored natural attenuation program for groundwater conducted from 2007 to 2008. The site has since received a No Further Action determination. 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 contamination here — petroleum from decades of vehicle fueling and maintenance, and tar applied as a construction sealant — originated from county operations that ran from the 1920s through the 1960s, well before 1986 when occurrence-based Commercial General Liability policies began carrying effective pollution exclusions. Carriers who issued CGL coverage to King County during that operational window wrote policies that could not have excluded these releases, and those policies remain potentially enforceable today. The remediation costs documented at this site — removal of over 10,000 cubic yards of impacted material and multi-year groundwater monitoring — represent the kind of expenditure that historical carriers may be obligated to recover.
Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.
Recovering Costs from an Older Cleanup
If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.
