Industrial & Manufacturing cleanup site — Restorical Research
Washington Cedar Supply
Kent, King County

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1929. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property in Kent served as an industrial storage and salvage operation, with a railroad spur line operating from at least 1929 through approximately 1990. Environmental investigations in 1988 and 1990 documented large-scale vehicle and debris storage along with twenty-two 55-gallon drums containing unknown substances. Cleanup activities across multiple parcels within the site have included drum and impacted-soil removal, groundwater remediation, and multi-year cleanup processes — some parcels have achieved No Further Action status while others remain in earlier stages of investigation or cleanup. 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.

Industrial storage and rail-served operations at this property began nearly six decades before 1986, placing the origin of potential contamination squarely within the era when occurrence-based Commercial General Liability policies provided broad pollution coverage without an effective exclusion. The presence of uncharacterized drums, documented soil impacts, and groundwater contamination across multiple parcels points to long-duration releases tied to decades of pre-1986 industrial use. Historical carriers whose policies were in effect during that operational window may be obligated to fund the investigation and remediation costs the property still faces.

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.
