Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance 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 served as the City of Lynnwood's Sewer Lift Station 10, a municipal utility operation in Snohomish County. An underground storage tank excavation was performed at the site, but soil contamination from the former UST area remains unresolved. The site is classified as a historical cleanup site under Ecology's Standard Cleanup program, with further investigation and cleanup action still required and potential remedial action grants of $200,000 to $300,000 identified for the work ahead. 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 at this site stems from underground storage tanks that were part of a municipal infrastructure operation old enough to be classified as historical, with the USTs and associated releases predating 1986. A government agency that owned and operated utility infrastructure during that era would have carried general liability coverage — and the occurrence-based CGL policies in force during the UST operating years at Sewer Lift Station 10 may still respond to the soil contamination that persists here. With investigation and cleanup costs still accruing, historical carriers could be obligated to fund both past remediation expenditures and the remaining work.

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.
