Industrial & Manufacturing cleanup site — Restorical Research
Pier 63 Sediments
1915 Alaskan Way, Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1906. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Originally constructed in 1906 as Pier 10 (Virginia Street Dock), this Seattle waterfront property was built on creosote-treated timber piles and operated for decades as a newsprint storage facility before being incorporated into the combined Pier 62/63 structure in the 1980s. Sediment surveys conducted in 1982 and 1985 documented historical contamination in the vicinity, with no evidence of recent accidental release — only the legacy of long-standing industrial waterfront operations. Between late 2022 and early 2023, the City completed the removal and demolition of Pier 63, including its creosote-treated piles, with post-construction sediment sampling and erosion control measures implemented; preparatory sampling reports also indicate potential future excavation of contaminated soils. 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 contamination at this site — polycyclic aromatic hydrocarbons (PAHs) leaching from creosote-treated timber piles — originates from a pier structure in continuous waterfront use since 1906, placing its contaminating operations more than eight decades before the 1986 threshold at which occurrence-based CGL policies began to include effective pollution exclusions. Pre-1986 carriers who issued policies to operators of this industrial waterfront property had no such exclusion and remain potentially liable under Washington law. The documented remediation costs — pier demolition, creosote pile removal, sediment sampling, erosion control, and prospective soil excavation — represent expenditures those historical carriers may be obligated both to recover and to fund as cleanup work continues.

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.
