Public Works cleanup site — Restorical Research
Kent Commons Playfield Ditch

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.

The Kent Commons Playfield Ditch is a storm drainage channel that receives runoff from upstream industrial properties in Kent. Elevated concentrations of petroleum hydrocarbons (NWTPH), arsenic, and mercury were detected in ditch soil samples in 1992 following citizen concerns, and the City of Kent Public Works reported the findings to Ecology by letter dated August 27, 1992. Follow-up sampling conducted in 2001 found contaminant concentrations below MTCA Method A cleanup levels, resulting in a no-further-action determination; no remediation or cleanup was performed. The site is not currently subject to periodic testing. 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.

This ditch functioned as the downstream receiving point for runoff from upstream industrial businesses whose operations almost certainly predate 1986 — and those upstream operators, not the City of Kent, are the parties whose historical CGL carriers may bear exposure for the government sampling this discharge triggered. The nine-year span from the 1992 citizen-prompted discovery to the 2001 follow-up sampling that finally produced the NFA reflects how long the liability question for those upstream operators remained unresolved under regulatory scrutiny. Pre-1986 occurrence-based policies issued to those industrial businesses carried no effective pollution exclusion and are the relevant instruments for any cost-recovery inquiry tied to this ditch.

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.

What We Look For

  • Historical insurance policies (pre-1986)

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.
