Landfill cleanup site — Restorical Research
Redondo Heights Park & Ride Lot

Preliminary Site-Specific Analysis

This property has a documented history as a landfill predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property functioned as an informal dump site prior to its development as the Redondo Heights Park & Ride Lot, with petroleum-impacted soil commingled with abundant wood and metal debris encountered in the southeast corner of the stormwater vault area. A separate area of contamination was identified beneath a former building where steam cleaning activities had taken place. Remediation consisted of excavating and disposing of approximately 4,800 cubic yards (6,797 tons) of petroleum-impacted soil offsite, followed by full-site asphalt capping to prevent exposure to any remaining impacted material. Ecology has issued a No Further Action determination for the site. 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 petroleum contamination here originated from a historical dump and former steam cleaning operations that predated the 2003–2004 Park & Ride construction — and almost certainly predated 1986, when occurrence-based Commercial General Liability policies were still written without an effective pollution exclusion. Nearly 4,800 cubic yards of contaminated soil required excavation and offsite disposal, and the entire property required capping: documented remediation expenditures tied directly to those pre-1986 historical uses. Historical carriers who issued CGL policies to the operators of this property during its dump and steam cleaning era may retain obligations to contribute to those cleanup costs.

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.
