Dry Cleaner cleanup site — Restorical Research
Rose Hill Plaza
Kirkland, King County
Restorical Research
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.

A dry cleaning operation at Rose Hill Plaza in Kirkland released tetrachloroethylene (PCE) into the surrounding soil and groundwater — contamination that included liquid dry cleaning waste stored in plastic bottles outside the business's back door and was detected during an environmental audit in the late 1980s. Cleanup commenced in September 1990 with the excavation and removal of 10 cubic yards of contaminated soil, followed immediately by continuous groundwater remediation through pumping and carbon adsorption treatment beginning in December 1990. Annual progress reports and monitoring were conducted through at least October 1998. 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 contamination at this site originated from chronic dry cleaning operations — investigators documented past releases at multiple locations on the property, reflecting an accumulation of historical practices rather than a single isolated spill. That pattern of release is consistent with activity spanning years before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The documented remediation record — soil excavation, years of active groundwater pumping and treatment, and long-term monitoring — traces directly to those pre-1986 operations, and the historical carriers whose policies covered the dry cleaning business during that window may remain obligated to fund the costs of cleanup.

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.
