Public Works cleanup site — Restorical Research
Bellevue Park Maintenance
Bellevue, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1960. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has served as the City of Bellevue's parks department maintenance yard since the early 1960s, with site buildings constructed in that era and a 10,000-gallon underground gasoline storage tank supporting fleet fueling operations. The UST required a fiberglass lining in 1983 due to groundwater ingress, leaked in 1988, and was removed in 1989 along with 425 cubic yards of contaminated soil. Subsequent cleanup under the Standard Cleanup program has included a soil vapor extraction system operated from 1990 to 1999, recovery of free-floating gasoline product through 2003, and ongoing annual groundwater and vapor monitoring continuing since 1989. 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.

Petroleum contamination at this facility originated from a gasoline UST that was installed and operated decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank removal, large-scale soil excavation, nine years of vapor extraction, product recovery, and more than three decades of monitoring — were incurred to address a release tied directly to those pre-1986 fueling operations. Because cleanup remains ongoing, historical carriers who issued CGL policies during the facility's early operational window may be obligated both to recover past costs and to fund the remediation work still ahead.

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.
