Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1939. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The former West Seattle Landfill operated at this property from 1939 to 1966, accumulating refuse deposits approximately 30 to 35 feet thick across what is now the SW Harbor Project site. Steel mill operations subsequently used the property for miscellaneous waste storage and disposal into the 1970s, followed by a scrap-metal processing facility operating from 1977 onward. Remediation has included excavation and consolidation of contaminated soil, slag, and landfill materials, installation of interim and final low-permeability cover systems, and implementation of landfill gas collection and treatment infrastructure. The site has reached cleanup completion and is currently in active long-term monitoring and operational maintenance. 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 contamination here originates from landfill operations that began in 1939 and concluded in 1966 — a quarter century before occurrence-based Commercial General Liability policies stopped reliably covering pollution claims in Washington. The documented remediation costs at this property — soil and slag excavation, engineered landfill covers, landfill gas collection and treatment systems, and continuing operational monitoring — represent expenditures tied entirely to releases generated within the pre-1986 policy window. Historical carriers who issued CGL policies to the landfill operators or the industrial users that followed may retain obligations to recover those 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.
