Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1980. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property was developed in 1980 as part of the Alderwood Shopping Center in Lynnwood, with H&H Dry Cleaners beginning operation shortly after — circa 1980–1981. Dry cleaning operations introduced tetrachloroethylene (PCE) and its degradation products — trichloroethylene (TCE), cis-1,2-dichloroethylene, and vinyl chloride — into the groundwater beneath the site. Remediation under the Voluntary Cleanup Program spanned two decades, from 2001 through 2021, and included operation of a dynamic vapor extraction system, installation of a permeable reactive barrier wall, and soil excavations. Ecology issued a No Further Action opinion in 2025, confirming that groundwater concentrations had been reduced below cleanup levels. 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.

H&H Dry Cleaners was operating at this site by 1980 or 1981 — several years before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. The chlorinated-solvent contamination documented here is characteristic of the slow, subsurface releases those policies were written to cover. Twenty years of remediation expenditures — vapor extraction, reactive barrier installation, and excavation campaigns — represent costs that historical carriers who insured the facility during its pre-1986 operational window may still be obligated to reimburse.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

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 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
