RE: Supplemental Report - Timber Retaining Wall Upper Tier
Project Location: 2815 Casco Point Road, Orono, Minnesota
Project No. 22-6589
Dear Mr. Prust:
This letter is being sent in response to the email we received from Melanie Curtis from the City of Orono.
Based on her review of my previous letter to you dated November 18, 2022, she is requesting additional
information.
It is my professional opinion that the work I recommended should qualify in regards to City Code Section
78-1726 (6): Emergency repair exception.
The slopes at the top of the timber retaining walls constructed to-date are much steeper than originally
designed. The construction of the final, planned retaining wall at the top of the tiered retaining wall system
is required to stabilize these slopes. Failure to stabilize and reduce the steepness of these slopes with the
construction of the planned wall will likely result in a slope failure, significant erosion, and damage to the
retaining walls already constructed.
Refer to my original design dated August 24, 2022, and my previous letter dated November 18, 2022, for
further information.
Please call me if you have any questions or need more information. Thank you.
Sincerely,
Paul Schimnowski, P.E.
