Catastrophic Retaining Wall Failure Goes to Court in St.Paul MN

What happens here

Examine the structural components of the retaining wall, specifically looking for 'dead men' (horizontal timbers or anchoring ties) that extend back into the soil. Note if these 'dead men' extend underneath existing structures like a driveway or the garage. Understand that if these anchors extend under structures built *after* the wall, it implies the original wall was not designed to support the additional 'surcharge' or weight from those structures.

Goal: Determine if the retaining wall's original design was adequate for current loads and if additional loads were added later.
