Car Dealerships cleanup site — Restorical Research
North Precinct
12800 Aurora Ave N, Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a automobile dealership predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

The property at 12800 Aurora Ave N has operated as an automotive dealership and repair facility, with prior ownership by Warren Westlund Buick GMC Inc. and Carland Auto Sales. Site investigation and characterization have identified diesel, gasoline TPH, petroleum oils, and 1,2-dichloropropane — a compound associated with paint strippers — in the subsurface, attributed to long-term auto repair activities and a former waste oil underground storage tank on the property. A program of quarterly groundwater monitoring has been recommended as part of potential multi-year site management; active remediation has not yet commenced beyond the investigation phase. 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 contamination documented here — petroleum hydrocarbons and a chlorinated paint-stripping compound from vehicle service and bodywork operations — reflects the kind of gradual, cumulative release that pre-1986 occurrence-based Commercial General Liability policies were written to address. The site's documented contamination is attributed to long-term auto repair activities rather than any discrete recent incident, which raises the plausibility that releases began during an era when such policies had no effective pollution exclusion. Carriers who issued CGL policies to the dealership's prior operators during that window may bear obligations both for investigation costs already incurred and for the multi-year groundwater management program now anticipated.

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.
