This property has a documented history as a gasoline service station going back to 1960. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Northshore School District operated a bus fueling station and transportation facility on this Bothell parcel from at least the 1960s, with underground storage tanks serving diesel and gasoline operations over several decades. Three USTs were removed in the 1960s during redevelopment of the site as the district's bus barn, a fourth was removed during a parking lot expansion in the 1980s, and three large tanks — two 10,000-gallon diesel and one 8,000-gallon gasoline — were removed in 2010. Groundwater investigations confirmed petroleum hydrocarbon contamination and polycyclic aromatic hydrocarbons exceeding MTCA cleanup levels. The site entered the Voluntary Cleanup Program and has since received a No Further Action determination from Ecology. 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.
Underground fuel storage operations at this site date to at least the 1960s — more than two decades before 1986, when occurrence-based Commercial General Liability policies ceased to be the industry standard. The petroleum and PAH contamination documented in groundwater here traces to tanks installed and operated during that pre-1986 window, when CGL policies carried no effective pollution exclusion. The remediation costs incurred across multiple UST removal campaigns and groundwater investigation represent expenditures that historical carriers who insured the district's fueling operations may still be obligated to cover.
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.
