This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property, identified as the Snohomish-Woodinville Road Right-of-Way, was managed by Snohomish County Public Works and became the subject of a Voluntary Cleanup Program investigation due to lead, diesel-range petroleum hydrocarbons, and oil-range petroleum hydrocarbons detected in soil and groundwater. Cleanup activities included remedial excavation of contaminated material, carried out over several years of assessment and remedial action. Those efforts culminated in a No Further Action determination under the Voluntary Cleanup Program. 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 lead contamination documented at this right-of-way is consistent with municipal operations conducted during the era of leaded gasoline, which was largely phased out before 1986 — the same period when occurrence-based Commercial General Liability policies were issued without effective pollution exclusions. Public works operations at this location during that pre-1986 window may have been covered by such policies, and historical carriers whose policies were in force when the contamination originated could bear responsibility for the excavation and remediation costs already incurred to reach the No Further Action determination.
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.
