Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This Kirkland property operated historically as a commercial and light industrial facility — previously identified as the Kirkland Commerce Center — before its current redevelopment as Google Building E. Contamination consisting of petroleum hydrocarbons, PAHs, and halogenated solvents including PCE and TCE was discovered in August 2020 during that redevelopment. Cleanup activities have included the excavation and off-site disposal of contaminated soil, with remediation proceeding as an independent action under the Standard Cleanup program. 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 hydrocarbons, PAHs, and chlorinated solvents of the type found here are the product of sustained commercial and industrial operations — not sudden releases — and the ERTS documentation characterizes the 2020 discovery as the identification of pre-existing contamination rather than a new incident. Investigation and soil excavation costs already incurred represent expenditures potentially recoverable from historical carriers whose occurrence-based CGL policies were in force when the contamination originated. With active remediation still underway, those same policies may also be obligated to fund the cleanup work yet to come.

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.
