Industrial & Manufacturing cleanup site — Restorical Research
Marysville Waterfront Park
Marysville, Snohomish County

Preliminary Site-Specific Analysis

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

This property has a documented industrial history stretching back to the late 19th century, when several lumber and shake companies operated mills on the site — predating Marysville's own incorporation in 1891. A railroad spur serving those operations was abandoned before 1984, and remnants of an old gasoline station were identified on Parcel D. Remediation work conducted between at least 1996 and 2005 included test pit excavation, backhoe exploration for underground storage tanks, soil removal, sediment removal, and the design of engineered caps for paved and landscape areas; cleanup is ongoing under the Voluntary Cleanup Program. 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 lumber and shake companies that operated on this property used pentachlorophenol as a wood preservative — the industrial practice that produced the contamination now requiring expensive remediation. Those timber operators would have carried occurrence-based Commercial General Liability policies during the decades they were active, and the carriers who issued those policies are potentially responsible for the documented remediation costs: soil excavation, sediment removal, and engineered caps. Because the contamination originated from industrial practices that began well before 1986 and continued through multiple operator tenancies, the pool of potentially liable historical insurers here is unusually broad.

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.
