Landfill cleanup site — Restorical Research
Lake Goodwin Landfill
Stanwood, Snohomish County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a landfill predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Lake Goodwin Landfill accepted municipal garbage, demolition debris, and industrial waste within a former Snohomish County gravel pit until debris filling was terminated in September 1982 and a final soil cover was placed during 1983. The closed landfill's cover remains subject to ongoing maintenance, and in October 1990 five groundwater monitoring wells were installed to support a quarterly program tracking leachate indicators and statistical groundwater trends. The site is classified as Awaiting Cleanup under Washington's Standard 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.

Waste disposal at this landfill continued into 1982, and documents note operations extending back through the early 1970s — placing the contamination source entirely within the era when occurrence-based CGL policies carried no effective pollution exclusion. Leachate from decades of mixed municipal and industrial waste disposal is precisely the slow, diffuse release that pre-1986 carriers assumed liability for when they wrote those policies. With active cleanup still ahead, historical insurers who covered the landfill's operators during its working years may be obligated to fund the investigation and remediation costs now facing this site.

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.
