PRACTICAL DIFFICULTIES <br /> For bank retention <br /> 1905 Concordia Street <br /> Orono, MN <br /> This repair project is difficult and complicated for several reason. <br /> 1. The bank of the lake has failed before and it is possible to uncover issues as you <br /> attempt to install the new shoreline bank. <br /> 2. With no other access the project has to be built from a barge on the lake. That means <br /> that all products and waste items must be loaded to a barge and then loaded on a truck <br /> to be taken for disposal. <br /> 3. Working on the bank from the bottom up requires digging into the bank to install the <br /> retention timbers for one level at a time without causing more erosion in the process. <br /> That means there is a lot of action at every level and as you move up the bank it get <br /> much more difficult to get supplies in and out while working on the bank. <br /> 4. This work requires experienced and skilled workers to function as a team from start to <br /> finish. <br /> 5. When the sub structure is complete the crew must hold the topsoil in place while they <br /> do the landscape planting of good bank retention plants. It is extremely difficult to <br /> move up and down the bank without causing erosion of the bank. Sometimes the crew <br /> must work down the bank while being tied to a rope and other times in requires to work <br /> from a bucket on a backhoe to finish the planting and erosion control materials on the <br /> bank.. <br /> 6. The Concept Landscape company has been doing this type bank restoration for some 30 <br /> year without a failure in the structure. It is very difficult and time consuming, but it is a <br /> real solution to some serious bank failures on lakeside slopes. <br /> Dale Gustafson <br /> Greendale Design <br />
