Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1900. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was acquired by the City of Seattle for the operation of a streetcar and later bus maintenance and fueling facility, with operations dating to the late 1890s and early 1900s. Gasoline contamination from the former bus barn triggered extensive cleanup under the Voluntary Cleanup Program, including excavation and disposal of over 418,700 cubic yards of contaminated soil, active in-situ air sparging and soil vapor extraction, and monitored natural attenuation with multi-year groundwater monitoring. Engineering controls — protective caps, chemical vapor barriers, and passive venting systems — remain in place, with ongoing maintenance and strict protocols governing any future ground disturbance. 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 gasoline contamination at this site originated from municipal fueling and maintenance operations that began nearly a century before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The scale of documented remediation — hundreds of thousands of cubic yards of soil removed, groundwater treatment systems deployed, and permanent engineering controls installed and maintained — represents substantial expenditures tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during that long operational window may be obligated both to recover past cleanup costs and to fund the ongoing monitoring and maintenance this site still requires.

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.
