This property has a documented history as a industrial and manufacturing facility going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The Interlake Sporting Association (ISA) was established in 1950 as an outdoor shooting range on a hill overlooking the Sammamish River Valley in Redmond, and there is no known source of lead in the surrounding area other than the shooting range. Decades of ammunition use have produced lead-contaminated surface runoff draining into Gun Club Creek, with initial investigations and a site hazard assessment now completed. The site is currently designated as Awaiting Cleanup under Ecology's Standard Cleanup program, with no active remediation 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.
Lead deposition at this property began with shooting range operations in 1950 — more than three decades before 1986, when occurrence-based Commercial General Liability policies still covered gradual environmental releases without an effective pollution exclusion. The slow, cumulative accumulation of lead from ammunition over those decades is precisely the type of long-running release those pre-1986 policies were designed to address. As the site moves toward active remediation, the costs of cleaning up lead-impacted soils and waterways could plausibly be funded by historical carriers who issued CGL policies during ISA's pre-1986 operational window.
