Lawsuit Blames Two Construction Firms for 2023 Park City Landslide

Nearly three years after a landslide rattled the hillside above the Marriott Mountainside hotel near Park City Mountain, an insurance company is pointing fingers at two construction firms it says caused the disaster.

Zurich American Insurance Company filed a lawsuit in late February 2026 alleging that Big-D Signature LLC and CRH Partners LLC performed work that directly triggered the slide, which occurred in late April 2023. The lawsuit seeks to hold both companies liable for damages stemming from the incident.

The landslide struck above the Marriott Mountainside, a resort property situated at the base of Park City Mountain, one of the region's busiest ski destinations. The timing, late in the 2023 spring season, raised immediate questions about whether ground disturbance from nearby construction had destabilized the slope.

Big-D Signature LLC is a construction firm, and CRH Partners LLC is named alongside it as a defendant. Zurich American, which would have paid out claims related to the landslide damage, filed the suit as a subrogation action, meaning the insurer is attempting to recover costs it already covered by pursuing the parties it holds responsible.

The lawsuit brings renewed attention to a 2023 incident that residents of the Canyons Village and surrounding neighborhoods may remember for the disruption it caused to one of Park City's most visible resort corridors. Whether the case proceeds to trial or settles out of court, the outcome could carry consequences for how construction activity near sensitive mountain terrain is supervised and insured across Summit County.
