Lilydale Landslide Caused by Natural Soil Erosion: Report

Two independent investigations showed no wrongdoing by city employees in their management of the Lilydale bluff that collapsed in May, killing two Peter Hobart students.

Despite knowing about the natural soil erosion at Lilydale Regional Park, St. Paul public officials could not have predicted the May landslide that took the lives of two Peter Hobart students, according to the findings of two independent reports, which were released Thursday morning.

"There was no evidence of actual knowledge of unstable bluffs that posed risks to the safety of visitors to the park and its Fossil Ground," the executive summary reads. "To the extent that the city possessed general knowledge of soil erosion within the park, it was insufficient to enable the city to predict and prevent the deadly slope failure at the East Clay Pit."

The investigators blamed the landslide on natural erosion "aggravated by groundwater migration during a very rainy spring and trampling of foot traffic along unmarked trails."

Fossil hunting permits will stay suspended as the city works on a visitor safety plan, but St. Paul Mayor Chris Coleman told Kare 11 that part of the park's attraction lies in its unpaved, off-the-beaten-track nature.

"Lilydale Park is a wonderful, wonderful part of the city," he said. "It is an untamed and wild area: that is part of its mystique, part of its wonder."

The two investigations were conducted by a legal, fact-finding team that reviewed documents and interviewed staffers and by an engineering team that looked at how the area's geology interacted with man-made devices such as storm sewers.
