Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1949. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property at 8914 14th Ave S in Seattle has been in continuous commercial and residential use since at least 1949, when the current building was constructed per King County tax records. A 1950 Sanborn Map depicts a plumbing supplier and storage facility alongside a sign painting and woodworking operation on the property, and city directories confirm South End Plumbing Co at this address by 1951. A Phase II environmental investigation in July 2021 confirmed groundwater concentrations of total petroleum hydrocarbons, arsenic, lead, dissolved chromium, and hexavalent chromium exceeding MTCA Method A cleanup levels. The site is currently awaiting cleanup under the Standard Cleanup program. 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.

Commercial and industrial operations at this property — plumbing supply, sign painting, woodworking — were established by the early 1950s, more than three decades before occurrence-based CGL policies ceased reliably covering pollution claims. The groundwater contamination confirmed here, including arsenic, lead, hexavalent chromium, and petroleum hydrocarbons, is consistent with the types of slow, cumulative releases that pre-1986 policies were written to address. The investigation and remediation costs this property now faces could plausibly be funded by historical carriers whose policies were in effect during those decades of pre-1986 commercial operations.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
