Following a landslide that seriously damaged the Jordan Brewery, the city is taking a closer look at conditions on the rain-soaked river bluff behind the historic building as well as other areas in town.
An engineering firm with expertise in soil mechanics, including evaluating the stability of natural slopes, recently examined three locations — immediately behind the brewery, behind a home about 1,000 feet north of the brewery and another area on the north bank of Sand Creek near one of the city's water towers.
The City Council agreed to pay Braun Intertec up $3,000 for a report on the conditions of each site and recommendations on what kind of work might need to be done.
In a memo to the council, Assistant City Engineer Mike Waltman said city staff had recommended the broader look at the hillside because "the slide may be larger in magnitude than is easily visible."
Braun Intertec's report was sent to the city last week and identified the slide behind the brewery as the one of greatest concern.
City Engineer Tim Loose hadn't yet seen the report but said stabilizing the area around the brewery "is not an easy fix."
The report didn't have a detailed plan for fixing the brewery site. But it said that at a minimum it would involve removing unstable soil and building a retaining wall. It said the work will be challenging for reasons that include getting into the area with construction equipment and the need to anchor the wall with pilings driven with a large crane from the front of the brewery building.
The report didn't provide a cost estimate for the project. However, the owners of the brewery recently were told by a different team of engineers that it would cost $7.5 million to stabilize what's left of the hill in back of their building. None of that would be covered by insurance; landslides typically are not covered by property insurance policies in Minnesota.
