Preliminary Site-Specific Analysis

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

Five Corners Cleaners operated as a dry cleaning tenant at 15605 1st Avenue South in Burien, with tetrachloroethylene (PCE) contamination traced directly to that tenant space — including a former sump and concrete drain line — where groundwater concentrations reached 13,000 ppb, the highest recorded on the property. Cleanup activities documented from 1991 to 2014 under the Voluntary Cleanup Program included sump excavation, former UST-associated excavation, and vadose-zone soil remediation at the 2 Roy Street parcel. Active solvent source removal has been achieved on the 15623 and 15607 First Avenue South parcels, though the project spanned more than two decades. 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 at this property was released through infrastructure — a sump and concrete drain line installed inside the dry cleaning tenant space — that was in place and operating well before 1986, meaning the subsurface occurrence that triggered environmental liability almost certainly predates the pollution-exclusion era. The more than two decades of documented VCP work across multiple parcels — sump excavation, soil remediation, UST-associated removal — represent costs tied directly to that dry cleaning tenancy and the slow solvent migration it generated. Historical carriers whose occurrence-based CGL policies were in force while Five Corners Cleaners was operating may be obligated to fund recovery of those expenditures.

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.
