Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

The Lakeview & Four Seasons Dry Cleaners continues to operate at its Mercer Island shopping center location, where both current and historical dry cleaning operations have released tetrachloroethylene (PCE) into the surrounding environment. Site investigations beginning in 2006–2007 — initially prompted by complaints of chemical odors — identified PCE and its degradation products (TCE, DCE, and vinyl chloride) in soil and groundwater; cleanup has included excavation and off-site disposal of 15 tons of PCE-contaminated soils. Remediation and waste management activities are projected to extend through at least 2025, spanning nearly two decades of documented cleanup effort. 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 15 tons of PCE-contaminated soil excavated here, the multi-year investigation running from 2006 through a planned 2025 waste disposal, and the ongoing remediation of a business still in operation all point to a contamination history rooted in the original dry cleaning machine and the solvent disposal practices of an earlier era. Occurrence-based CGL policies in force during the pre-1986 phase of those operations carried no effective pollution exclusion under Washington law and remain enforceable today. Historical carriers who covered this location during that window may be obligated to fund a portion of the documented and future cleanup costs.

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.
