Car Dealerships cleanup site — Restorical Research
South Waterfront - Block 44
Multnomah County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as an automobile dealership predating 1986. Historical insurance policies issued during operations at this property and through 1986 could help fund the ongoing and future cleanup under Oregon DEQ oversight.

This property in Portland's South Waterfront district operated as the Balsiger Motor Co automotive dealership and was excised from the larger Prometheus contamination site (ECSI 4007) in July 2017. Petroleum contamination has been confirmed in groundwater and soil gas, with vapor intrusion identified as a concern beneath structures on the site. Oregon DEQ assigned the site for active oversight, and as of 2024, a vapor intrusion mitigation system was being installed in conjunction with new building construction — work that continues into 2025 with no No Further Action determination issued. That history could support an insurance coverage claim against the carriers who issued policies more than 40 years ago — coverage that could help fund the cleanup ahead.

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 Oregon — and those policies may provide coverage that remains enforceable today. 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 petroleum contamination at this former automotive dealership in Portland's South Waterfront district originates from commercial operations that predate 1986. With no No Further Action determination issued, the ongoing vapor intrusion mitigation, groundwater monitoring, and continued investigation under Oregon DEQ's active oversight represent substantial cleanup costs going forward that historical pre-1986 carriers may be obligated to fund.

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 viable insurance coverage exists to fund the cleanup, 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.
