Industrial & Manufacturing cleanup site — Restorical Research
Harbour Village Marina

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1965. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has a layered industrial history: a landfill operated on-site from 1965 to 1981, a navigation channel was constructed in 1981, and underground storage tanks — one holding used oil and bilge water for the marina, another containing diesel fuel associated with a former lumber yard — were installed by at least 1983. Cleanup under a 2001 Consent Decree has included the removal of two USTs and contaminated soil, past sediment dredging totaling nearly 69,000 cubic yards, ongoing groundwater monitoring, and planned dredging of an additional 31,700 cubic yards with sediment capping. 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 Harbour Village Marina traces to industrial operations spanning 1965 through at least 1983 — a landfill, a lumber yard's diesel tank, and a marina's used-oil storage — all of which predate the 1986 shift to claims-made pollution exclusions. Any CGL carrier on risk when those specific tanks were installed in 1983, or when the landfill was accepting waste through 1981, issued occurrence-based policies that responded to exactly this kind of gradual release. The remediation costs already incurred under the Consent Decree and the substantial dredging and capping work still ahead represent obligations those historical carriers may be required to fund.

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.
