Public Works cleanup site — Restorical Research
I-5 NB at E Portland Ave
Tacoma, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

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

This WSDOT-owned property along the northbound I-5 corridor at East Portland Avenue in Tacoma yielded lead, chromium, and benzene contamination when excavation work began during an I-5 construction project in 2019. The contamination was pre-existing in the soil rather than a product of the construction itself. Remediation has involved excavating the impacted soil and transporting it off-site to LRI for disposal, with PBS Environmental conducting the cleanup effort 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.

Lead, chromium, and benzene are legacy contaminants whose presence in soil beneath a major transportation corridor strongly implies accumulation well before 1986 — the period when leaded gasoline was still in active use and occurrence-based Commercial General Liability policies had no effective pollution exclusion. Carriers who issued CGL policies to operators or contractors active at or adjacent to this corridor during that pre-1986 window may be obligated to fund the excavation and disposal costs now being incurred to address contamination that originated on their watch.

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.
