This property has a documented history as a dry cleaning facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
Gateway Plaza at 18336 Midvale Ave N in Shoreline historically housed both a gasoline service station and a dry cleaning operation. A Phase II environmental assessment identified tetrachloroethylene (PCE) contamination in soil directly beneath the former dry cleaning machine location, along with petroleum and solvent impacts to soil and groundwater. Independent remedial actions under the Voluntary Cleanup Program — including over-excavation and offsite disposal of PCE-impaired soil — successfully addressed the contamination, and the Department of Ecology issued 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 PCE release at Gateway Plaza traces directly to dry cleaning machinery that operated at this property before 1986, during the era when occurrence-based CGL policies routinely covered exactly this kind of slow solvent migration without a pollution exclusion. The documented remediation costs here — environmental assessment, soil excavation, offsite disposal, and regulatory oversight through the Voluntary Cleanup Program — are the type of cleanup expenditures that historical carriers who insured the dry cleaning and gas station operations may still be obligated to reimburse.
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.
