Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Bellevue Plaza site at 117 106th Avenue NE contains chlorinated solvent contamination traced to a former dry cleaning operation, Kwik Cleaners, as well as petroleum contamination from a former gas station and historical heating oil tanks on the property. A multi-year Remedial Investigation, Feasibility Study, and Cleanup Action Plan conducted between 2016 and 2020 involved extensive soil borings, monitoring well installations, and borehole abandonments. An Independent Cleanup Action was completed during that period, including excavation of contaminated soils, yet chlorinated solvent contamination above cleanup levels remains near the former dry cleaner's footprint. The site remains in Washington's Standard Cleanup program as the remediation process continues. 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 PCE and TCE plume at this property — along with petroleum releases from the former gas station and heating oil tanks — originated from operations that predate 1986; sampling conducted as far back as 1992 confirmed the contamination was already present, placing the original releases years or decades earlier. Occurrence-based Commercial General Liability policies issued to the dry cleaning and gas station operators during that pre-1986 window covered exactly this category of slow, ongoing environmental release, without the pollution exclusions that became standard after 1986. With further remediation costs ahead — additional soil and groundwater treatment, long-term monitoring, and potential follow-on cleanup actions — the historical carriers who insured Kwik Cleaners and the former service station during their operating years remain plausible sources of cost recovery.

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.
