Industrial & Manufacturing cleanup site — Restorical Research
Sound Transit Tacoma Trestle Project
Tacoma, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1873. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Railroad operations and wood products manufacturing were established at this Tacoma property as early as 1873, with documented site development continuing through the 1900s, 1908, and into the 1940s and 1970s. Contamination — petroleum hydrocarbons, metals, and polycyclic aromatic hydrocarbons (PAHs) — is attributed to decades of creosote use and railroad maintenance and repair activities across that industrial history. Remediation in 2016 included excavation around six characterization potholes, removal of contaminated soil in a 10-foot radius around an observation well, disposal of additional contaminated materials, and cyclical groundwater pumping, conducted as part of a broader multi-year construction and remediation effort. 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.

Creosote-derived PAH contamination is the textbook example of slow, continuous release: compounds deposited through routine railroad maintenance over decades migrate gradually into soil and groundwater rather than arriving as a discrete spill. That migration pattern — documented here from operations beginning in 1873 — is exactly how occurrence-based CGL policies issued to this site's operators before 1986 were triggered, with each policy period potentially capturing a separate covered occurrence. Historical carriers whose policies were in force during the site's long span of railroad and industrial activity remain the most direct avenue for recovering the documented remediation expenditures incurred during the mid-2010s 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.
