Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a farm and agricultural operation going back to 1972. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property operated as the Julius Rosso Wholesale Nursery Co., a wholesale nursery with on-site gas and diesel underground storage tanks for fueling agricultural equipment. Three USTs and associated product lines were removed in 1997 and 1998, with approximately 3.5 tons of petroleum-contaminated soil excavated and disposed off-site and an additional 10 cubic yards landfarmed on-site. Confirmed groundwater contamination with halogenated pesticides — likely associated with long-term nursery operations rather than the UST releases — remains documented at the site, which is currently awaiting cleanup 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 nursery were likely installed around 1972–1973 based on standard tank lifecycle analysis, placing the onset of petroleum operations well before 1986. Occurrence-based CGL policies issued during that pre-1986 operational window carried no effective pollution exclusion in Washington and remain enforceable today. With the site still awaiting cleanup for halogenated pesticide contamination in groundwater — on top of the petroleum remediation already completed — the property faces additional investigation and remediation costs that historical carriers may be obligated 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.
