This property has a documented history as a farm and agricultural operation predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
Longacres Park was historically developed as a horse racing facility, with barns and stables occupying the site prior to Boeing's acquisition of the property in 1990. Underground storage tanks associated with the former racetrack operations were previously reported to Ecology as sources of contamination, characterized in the investigation record as historical releases. Environmental investigation and monitoring were conducted in 2020 and 2021; proposed cleanup measures include land-use restrictions, prohibition of groundwater use, installation of vapor barriers, and a soil management plan, with active remediation not yet commenced. 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 UST releases at this property originated from racetrack operations that predate 1986, the threshold year after which pollution exclusions became standard in Commercial General Liability policies. Washington occurrence-based CGL policies in effect during those pre-1986 racetrack operations carried no effective pollution exclusion and remain enforceable against the carriers that issued them. The full scope of anticipated expenditures here — institutional controls, engineering controls, long-term monitoring, and eventual site remediation — represents costs that historical insurers whose policies covered the Longacres facility before 1986 may be obligated to fund.
