Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1889. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property at 3307 Fremont Ave N operated as a lumber mill and door company from 1889 through 1957, then as an industrial and commercial park until its redevelopment in the late 1990s, with a former railroad right-of-way traversing the site and contributing to its contamination profile throughout that span. The site was listed for cleanup in 1990; remediation centered on the excavation and removal of approximately 8,650 cubic yards of TPH- and PAH-contaminated soil from the railroad right-of-way beginning in August 1998, along with demolition of two buildings and their foundations as part of site redevelopment. A No Further Action determination was issued in 1999 following completion of the cleanup work. 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.

Industrial activity at this site stretches back to 1889 — nearly a century before 1986 — encompassing a lumber mill, a door company, rail operations, and an industrial park, all of which are directly associated with the petroleum hydrocarbon and PAH contamination documented in the soil. Occurrence-based Commercial General Liability policies issued to operators of this property during those decades carried no effective pollution exclusion under Washington law and remain legally enforceable today. The remediation costs here — over 8,600 cubic yards of excavated contaminated soil, structural demolitions, and a decade of regulatory process — were incurred to address releases tied to those long-standing pre-1986 operations, and historical carriers whose policies were active during that window may be obligated to fund a portion of those expenditures.

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.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
