This property has a documented history as a dry cleaning facility going back to 1960. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
This property at 4701 Brooklyn Ave NE in Seattle operated as the Carson Cleaners dry cleaning facility from the 1960s through approximately 2014, with tetrachloroethene (PCE) and its breakdown products released to soil, groundwater, and soil vapor during that period. A remedial investigation has been underway since at least 2016, including multi-year groundwater monitoring and sampling through perimeter monitoring wells that have since been abandoned. No active cleanup work has commenced, and the site remains in the awaiting-cleanup 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.
Dry cleaning operations at this property began in the 1960s — more than two decades before 1986, when occurrence-based Commercial General Liability policies still lacked effective pollution exclusions. The PCE contamination detected in soil, groundwater, and soil vapor here is precisely the type of slow, ongoing release those pre-1986 policies were written to cover. The investigation costs already incurred, and the remediation expenditures ahead, could plausibly be funded by historical carriers whose policies were in force during the decades when Carson Cleaners was actively operating.
