Restorical Research
Preliminary Site-Specific Analysis

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 fund a cleanup — and recover costs already spent.

This property served as a maintenance facility operated by the Lake Washington School District. A February 1989 Ecology enforcement order confirmed petroleum and benzene contamination in groundwater and soil, with benzene detected at 300 ppb in a monitoring well; suspected PCBs, heavy metals, and solvents were also identified. Underground storage tanks retrofitted in 2007 indicate the original USTs were likely installed before 1982, based on a standard 25-year tank lifecycle. Cleanup is ongoing, with confirmed diesel-range petroleum hydrocarbons in groundwater. 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 original underground storage tanks at this maintenance facility were likely installed before 1982, placing them within the era when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion. By 1989, Ecology had already documented petroleum and benzene contamination in soil and groundwater traceable to those operations. The remediation costs incurred since — investigation, monitoring, and ongoing cleanup — represent expenditures that historical carriers who issued CGL policies during that pre-1986 operational window may be obligated both to recover and to fund going forward.

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.
