This property has a documented history as a automobile dealership going back to 1920. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property at 1525 11th Ave in Seattle operated as an automobile sales and repair facility in a building constructed in the 1920s, with an underground storage tank used for heating oil from the 1950s until 1985 and hydraulic lifts used for auto maintenance. Cleanup under the Voluntary Cleanup Program has included multiple phases of soil excavation removing at least 312 and 111 tons of impacted material respectively, UST closure in place with cleaning and concrete filling, and ongoing semi-annual and annual groundwater monitoring. Future work includes further groundwater delineation, potential cleanup plans, and replacement of monitoring wells, with excavation-related shoring estimated at $80,000–$100,000 and soil removal running $4,000–$5,000 per cubic yard. 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.
Petroleum contamination at this property — from a heating-oil UST operated from the 1950s through 1985 and from hydraulic lift equipment used in auto maintenance — originated entirely from operations predating 1986, when occurrence-based Commercial General Liability policies still lacked effective pollution exclusions in Washington. The documented cleanup costs already incurred — multiple excavations, UST closure, and years of groundwater monitoring — combined with projected future expenditures for delineation, additional cleanup, and well replacement represent a substantial and ongoing liability trail. Historical carriers who issued CGL policies during the decades of pre-1986 automobile service operations at this site may be obligated both to recover costs already spent and to fund the cleanup work that remains.
