RE: Limestone Block Retaining Wall Evaluation
3205 Graham Hill Road
Orono, Minnesota
Project No. 13-1067
Dear Mr. Danforth:
This letter is being sent per your request regarding the recently constructed limestone block retaining
walls at 3205 Graham Hill Road in Orono, Minnesota. This evaluation is based on observations I made
during a site visit on November 4, 2013, construction progress photos provided by you on October 29,
2013, and verbal statements made to me by you regarding construction means and methods.
The construction of the retaining walls, including the tiered walls, appears to be structurally stable and in
general conformance with boulder/stone retaining wall and construction industry standards. The walls
were constructed with boulders of sufficient size and setback. Other typical construction details such as
use of drainage elements and filter fabric also appeared to be followed correctly. As is normal for boulder
retaining walls of this type, some wall movement and soil settlement should be expected.
I recommend that gutters and downspouts be installed on the house in order to direct the roof runoff away
from the retaining walls. Surface water should also be directed away from the walls.
This evaluation was performed using the design guidelines presented in the third edition of the"Design
Manual for Segmental Retaining Walls" (DMSRW)published by NCMA in 2009. If soil conditions,
proposed layouts, or other design parameters vary from that assumed a revised analysis might be needed.
Please call me if you have any questions or need more information. Thank you.
Sincerely,
Paul Schimnowski, PE
