Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1888. Historical insurance policies issued during those prior operations and through 1986 could help fund the multi-phase investigation and remediation work ahead under Wisconsin DNR oversight.

This property along the west bank of the Sheboygan River has been in continuous commercial and industrial use since the late 1880s, with documented operations including woodworking manufacturing, engine and autobody repair, cold storage, and railroad warehouse facilities served by multiple rail spurs that operated on and adjacent to the site for over 80 years. A 2024 site investigation confirmed widespread historical fill containing RCRA metals and polycyclic aromatic hydrocarbons (PAHs) at depths up to eight feet, and groundwater sampling across multiple monitoring wells revealed exceedances of Wisconsin NR 140 enforcement standards for lead, arsenic, and several PAH compounds including benzo(a)pyrene. Remedial action has been approved under the Wisconsin DNR Environmental Remediation Program, including soil excavation, capping beneath road and sidewalk construction in the public right-of-way, and a deed restriction on a former railroad parcel. 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 Wisconsin — 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.

Industrial and commercial operations at this property — including woodworking manufacturing, engine and autobody repair, cold storage, and railroad warehouse activity — began in the late 1880s and continued through decades of use well before 1986, a period during which contamination from those operations was being deposited into soil and groundwater across the site. The approved remedial action plan — encompassing soil excavation, capping beneath public right-of-way construction, deed restrictions, ongoing groundwater monitoring for NR 140 exceedances, and additional investigation and remediation work required under Wisconsin DNR Environmental Remediation Program oversight — represents substantial future costs 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.
