The walls were constructed to replace tleteriorated walls on the property. After phone discussions with the retaining wall contractor, we believe the walls were constructed using typical timber wall construction practices. The walls are approximately four feet tall and are supported with timber"deadmen"at reasonably spaced intervals. Also, the contractor states that drainage was provided behind the wall. We believe this is an adequate installation. Since no design drawings or calculations were submitted prior to wall construction,we did not conduct an engineering review. Bonestroo does not assume any liability for these walls. If you have any questions, please call me at(651) 604-4835.
