Industrial & Manufacturing cleanup site — Restorical Research
Lakeridge Paving Auburn

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1975. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property hosted a succession of commercial and industrial operations dating to at least 1975, including Burlington Northern Santa Fe Railroad activities (1975–1980), Cascade Concrete (1980), and Speedy Mix Concrete (1984), following decades of rural residential and agricultural use from the late 1930s. A Remedial Investigation has confirmed that tetrachloroethylene (PCE) exceeds MTCA Method A cleanup levels in groundwater at the site, with a completed soil-to-groundwater contamination pathway. Cleanup is underway 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.

The industrial operations at this property began more than a decade before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The PCE contamination detected in groundwater here — a halogenated solvent commonly associated with industrial operations of that era — represents the type of gradual, subsurface release those policies were written to cover. Historical carriers who insured the operators during the pre-1986 window may be obligated to recover remediation costs already incurred and to fund the cleanup work that remains 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.
