Preliminary Site-Specific Analysis

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

This West Seattle property served as Yard 2 of Lockheed Shipbuilding Company before the Port of Seattle acquired it in 1992. Contamination documented at the site — PCBs, heavy metals, and polycyclic aromatic hydrocarbons (PAHs) — is consistent with decades of heavy industrial shipyard operations. Remediation under a 2013 Record of Decision and a 2015 Unilateral Administrative Order has included sediment dredging, placement of cover material, riprap, and a sheetpile wall for containment. Lockheed Martin is responsible for remediation costs and for indemnifying the Port, with operation, maintenance, and monitoring continuing under environmental covenants. 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.

Lockheed Shipbuilding operated Yard 2 until at least sometime before the Port's 1992 acquisition, placing its active industrial period squarely within the window when occurrence-based CGL policies carried no effective pollution exclusion in Washington. The PCBs, heavy metals, and PAHs now embedded in the sediments are the direct legacy of those shipyard operations, not a recent incident. Environmental covenants and monitoring obligations imposed by the 2013 ROD and 2015 Unilateral Administrative Order mean remediation expenditures are ongoing with no near-term end date, and historical carriers whose policies covered Lockheed Shipbuilding's operations at Yard 2 during that pre-1986 period may still be obligated to fund those continuing 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.
