Public Works cleanup site — Restorical Research
West Seattle Golf Course 92 LUST
Seattle, King 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 recover the cleanup costs already paid.

This municipal property served as a maintenance facility for the West Seattle Golf Course, with underground storage tanks dispensing gasoline and diesel for operational vehicles and a separate heating oil UST for building heat. Two UST removal events were conducted under state oversight — gasoline and diesel tanks with associated product lines and dispensers were removed in 1999, and a heating oil tank was removed in 2005. The site received a No Further Action determination 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 underground storage tanks at this facility were installed and operated well before 1986, during the era when occurrence-based Commercial General Liability policies provided broad pollution coverage without an effective exclusion. Petroleum releases from those leaking USTs — documented across two separate removal events and triggering formal state cleanup oversight — represent the type of long-duration contamination event that pre-1986 CGL policies were designed to cover. Historical carriers who issued policies during the tanks' operational life may be obligated to recover the remediation costs incurred across both removal events and associated cleanup work.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

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 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
