Preliminary Site-Specific Analysis

This property has a documented history as a automobile dealership predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

Mallory Buick operated as a Buick dealership at this Westlake Avenue North property, with underground storage tanks and service infrastructure in place until the business went vacant in the early 1980s. The buildings were demolished in 1990, at which point six USTs, sumps, hydraulic cylinders, and associated trenches were removed and subsurface investigation began. Between 1990 and 1994, approximately 8,438 cubic yards of petroleum-contaminated soil were excavated and disposed of off-site; groundwater monitoring followed through 1995. Washington Ecology issued a No Further Action determination in 2012. 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 petroleum contamination at this former dealership originated from underground storage tanks installed and operated well before the business went vacant in the early 1980s — squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented remediation work — six UST removals, nearly 8,500 cubic yards of soil excavation, backfilling, and multi-year groundwater monitoring — represents a defined body of cleanup expenditure tied to those pre-1986 operations. Historical carriers who issued CGL policies during Mallory Buick's operating years may still be obligated to recover those costs.

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.
