Industrial & Manufacturing cleanup site — Restorical Research
Lynnwood Plating
19420 21st Ave W, Lynnwood, Snohomish County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1967. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Lynnwood Plating operated a chrome, nickel, and brass plating facility at this Lynnwood address from at least July 1967 through 1999, using chromium, nickel, brass, and sulfuric acid to refinish steel and aluminum automobile bumpers and parts. Remediation evidence includes a pond filled with soil, contaminated soil covered with fill, and contaminated sludge covered with gravel. The site was enrolled in the Voluntary Cleanup Program from 1999 to 2007 and re-entered the program in 2025, reflecting a multi-decade remediation effort that remains ongoing. 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.

A site inspection conducted in October 1986 documented active plating operations here — placing Lynnwood Plating squarely within the window when occurrence-based CGL policies were still the industry standard and carried no effective pollution exclusion for heavy-metal releases. The chromium, nickel, and acid contamination now embedded in the soil and sludge at this property is the direct residue of more than two decades of those pre-1986 operations, and the remediation costs — pond filling, soil cover, sludge stabilization, and ongoing VCP oversight — represent expenditures the historical carriers 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.
