Public Works cleanup site — Restorical Research
Seattle City DOT Maintenance Yard
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1906. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property has served as the Seattle Department of Transportation's Fremont Bridge maintenance shop yard since approximately 1906, making it one of the longest-running municipal operations in the region. Day-to-day activities at the facility have involved the handling, storage, and disposal of paints, solvents, and petroleum products across more than a century of continuous use. Contamination at the site includes lead-contaminated soil, petroleum hydrocarbons, tetrachloroethylene from solvent use, and creosote-contaminated wood. Remediation plans call for contaminated soil excavation, dewatering, and specialized handling and disposal of hazardous waste in connection with upcoming construction activities. 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 documented here — lead, petroleum hydrocarbons, chlorinated solvents, and creosote — is the direct result of routine maintenance operations that began more than eight decades before 1986, the year occurrence-based Commercial General Liability policies stopped reliably covering pollution claims. Carriers that issued CGL policies to the facility's operators during that pre-1986 window wrote those policies under forms with no effective pollution exclusion in Washington State. The soil excavation, dewatering, and hazardous-waste disposal costs now contemplated represent expenditures that those historical carriers may still be obligated to fund.

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.
