Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1958. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup.

This property has operated as a public road maintenance facility since the late 1950s — originally as the Brugger's Bog King County Maintenance Facility and subsequently as a City of Shoreline road maintenance yard — with infrastructure including a fleet vehicle fueling area, a vactor waste decant facility, and a construction materials and equipment storage yard. Site investigation has identified petroleum- and VOC-impacted soils exceeding MTCA cleanup levels along with groundwater impacts; drill cuttings generated during investigation have been containerized pending disposal. Planned remediation includes excavation and off-site disposal of contaminated soils, groundwater dewatering and disposition, and potential long-term monitoring, but no active cleanup work has yet commenced. 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.

Fleet fueling and road maintenance operations at this site began in the late 1950s and continued for decades before 1986, when occurrence-based Commercial General Liability policies still lacked effective pollution exclusions in Washington. The petroleum and VOC contamination documented in soil and groundwater here is consistent with the slow, ongoing releases that those policies were written to cover. The excavation, soil disposal, groundwater dewatering, and long-term monitoring now planned for this site represent substantial future expenditure, and historical carriers whose policies were in force during the pre-1986 operational window may be obligated to fund the upcoming remediation costs.

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.
