Landfill cleanup site — Restorical Research
Holly Street Landfill
Bellingham, Whatcom County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1937. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Holly Street Landfill operated as a municipal waste disposal site on private tidelands beginning in 1937, with initial filling activities dating to as early as the late 1800s and around 1905. Waste deposited at the site included glass, concrete, household debris, metal scrap, coal slag, ashes, and woody debris — material consistent with sanitary landfill practices of that era, with operations continuing through 1953. Remedial action initiated in 2003 has included shoreline excavation of solid waste, installation of engineered passive gas venting and mitigation systems, placement of two-foot soil caps, and institutional controls, with performance monitoring ongoing. 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.

The contamination at this Bellingham shoreline site — landfill gas migration and leachate from decades of municipal solid waste disposal — originated from operations that ceased in 1953, more than thirty years before the 1986 shift away from occurrence-based Commercial General Liability policies. Slow, ongoing migration of soil gas and leachate from buried waste is precisely the type of gradual, continuous release that pre-1986 CGL policies were written to cover. Carriers who issued occurrence-based policies to the operators or landowners during the 1937–1953 operational window may still be obligated to fund the remediation expenditures — excavation, capping, gas venting infrastructure, and long-term monitoring — that continue to accumulate at this site.

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.
