Restorical Research
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.

This site encompasses a tetrachloroethylene (PCE) and trichloroethene (TCE) groundwater plume originating from Campus Fine Dry Cleaning (4100 Roosevelt Way NE), an active dry cleaning business upslope from the affected area. Initial response work has included the excavation and off-site disposal of approximately 1,322 cubic yards of PCE- and petroleum-contaminated soil, installation of constructed drainage systems to manage groundwater, and vapor intrusion mitigation features with contingency provisions for active sub-slab depressurization. The plume extends northward and westward, with detections above MTCA Method A cleanup levels in groundwater adjacent to parking lot W41, and long-term groundwater and indoor air monitoring continues under institutional controls. 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 PCE and TCE contamination traced to Campus Fine Dry Cleaning reflects the type of slow, ongoing release associated with pre-1986 dry cleaning operations, when occurrence-based Commercial General Liability policies had no effective pollution exclusion. With the plume still migrating and full remediation yet to come, the costs ahead — groundwater treatment, extended monitoring, and potential active depressurization — are precisely the kind of expenditures that historical carriers whose policies covered those pre-1986 operations may be obligated to fund.

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.
