<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />June 13, 2022 Project VEC 21-230 <br /> <br /> <br />Mr. Dave Durkin <br />Boulder Creations Unlimited <br />309 Newton Avenue SE <br />Watertown, MN 55388 <br /> <br />Dear Mr. Durkin: <br /> <br />Re: Wall Evaluation, 1354 Rest Point Circle in Mound, Minnesota <br /> <br />As you requested, Vickery Engineering & Consulting, LLC (VEC) has performed visual observations of <br />the existing timber walls at the referenced location. As requested, I’m writing this letter to discuss the <br />evaluation of the existing timber walls. <br /> <br />Background Information <br /> <br />VEC prepared final design and construction drawings for the new retaining walls on this project. The <br />plans prepared are titled “Proposed Timber Retaining Walls, 1354 Rest Point Circle, Mound, Minnesota", <br />and were dated 6/4/2022. The project number for the plans was VEC 21-230. <br /> <br />Site Observations <br /> <br />VEC performed observations of the existing retaining walls last fall. At that time, the walls were <br />observed to be leaning outwards, with many of the timbers showing indications of the decay of the wood. <br />Several of the walls showed indications that the face of the wall was pulling away from the deadmen that <br />are anchoring the wall face in place. <br /> <br />Discussion <br /> <br />The existing walls are essential in holding the slope in place during construction. In order to keep the <br />slope from falling into the lake, shoring will be required to keep the existing soils on the slope. There is <br />no way to get a pile driving rig into the back yard to provide sheet piling for shoring, so leaving the <br />existing walls in place and building in front of the walls is the only way to repair the walls on the slope. <br /> <br />Conclusions <br /> <br />Based on our on-site observations, it is our opinion that if the walls aren’t repaired in the near future, the <br />entire slope will likely end up in the lake, walls and all. The potential for failure increases every day that <br />passes, and failure could be imminent, especially if there are any large rain events in the new future.
