Preliminary Site-Specific Analysis

This property has a documented history as a landfill predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Factoria Pit Sunset Park site in Bellevue is a former landfill that had been abandoned prior to a King County Health Department survey conducted from October through December 1984. That 1985 survey, undertaken to identify public health problems at abandoned landfill sites in King County, found potential environmental hazards and recommended additional sampling along with measures to control leachate migration and methane generation. No completed cleanup or remediation activities are documented, and the site remains in the Awaiting Cleanup phase. 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.

This landfill was in active operation before its abandonment prior to 1985, placing its operational history entirely within the era when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The hazards the 1984 survey identified — leachate migration and methane generation — are the kind of slow, ongoing environmental releases those pre-1986 policies were written to address. As the site moves toward active remediation, historical CGL carriers whose policies were in force during the landfill's operational years may be obligated to fund the cleanup costs ahead.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

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 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
