This property has a documented history as a landfill going back to 1926. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The Montlake Landfill began operating on University of Washington property in 1926 under an arrangement with the City of Seattle, functioning as both a general landfill and fire dump for approximately forty years while receiving 40 to 60 percent of Seattle's municipal and industrial garbage. Stabilization measures during the landfill's active period included dike construction from 1959 to 1969 to prevent pollutant percolation into Lake Washington, installation and operation of a methane gas collection and combustion system in the 1960s, and formal closure activities — rubble and soil fill spreading, final grading, and seeding — completed between 1969 and 1971. Contamination at the site was identified in 1999 and is attributed to those historical landfill operations; the site is enrolled in the Standard Cleanup program and awaiting active remediation. 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.
Four decades of municipal and industrial waste disposal at this property — from 1926 through the mid-1960s — produced the contamination now pending remediation, with releases tied entirely to operations that predated 1986 by decades. Occurrence-based Commercial General Liability policies issued to the operators and responsible parties during those landfilling years carried no effective pollution exclusion under Washington law. Historical carriers whose policies were in force during the site's active disposal period may still be obligated to fund the investigation and cleanup costs the property owner now faces.
