As requested,I'm writing this letter to discuss the <br /> evaluation of the existing timber walls. <br /> Background Information <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 /> Site Observations <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 /> Discussion <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 /> Conclusions <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. <br /> • <br /> Engineering.5olutions Foran(Instable World <br />
