Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a property with a heating oil tank going back to 1915. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property at 1823 Eastlake Ave E has a documented commercial history dating from 1915, when the Eastlake Fuel Company began operations on site. A restaurant was constructed in 1933 and heated by an oil-burning furnace with underground storage tanks — two oil furnaces and tanks are listed in 1959 building permits — while a furniture repair facility with paint spraying also operated on the property from 1937 to 1951. The heating system was converted to natural gas in 1966, and a 300-gallon heating fuel oil UST was removed in April 2015. Investigation identified halogenated solvents, benzene, and petroleum-diesel contamination in groundwater; the site has achieved No Further Action status under the Voluntary 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.

Commercial operations at this property date from 1915, with oil-fueled heating systems installed by 1933 and maintained through 1966 — decades of operation squarely within the occurrence-based CGL era that ended in 1986. The contamination documented in groundwater here — halogenated solvents, benzene, and petroleum hydrocarbons — is consistent with the types of slow releases that pre-1986 policies were written to cover. Historical carriers who issued CGL policies during those decades of fuel storage and commercial operations may hold obligations to fund the investigation and remediation costs incurred at this site.

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)

  • Claims Management & Forensic Accounting

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.
