2a(2). GRADE THE BANK AND USE GOOD UPLAND MANAGEMENT PRACTICES TO PREVENT FURTHER EROSION
It is assumed that a forested bank at this height is not providing a significant water quality benefit because the groundwater comes out of the bank below the root zone, and surface water, even if slowed by the trees, will still induce erosion as it comes over the bank. Removing some of the forest by grading back in order to attain a sustainable stable slope is the preferred action.
Very tall banks are difficult to stabilize because of their height and potential for catastrophic collapse. Extreme care should always be used when constructing houses at the top of a tall bank. Structures should be located as far back as the property will allow. Where structures already exist at the top of a tall bank, serious consideration should be given to moving the structure to a safer location on the property.
Go back to the decision tree and continue to Question 5. This will lead you to an additional recommendation for your shoreline. Use both recommendations on the shoreline for improved erosion protection. |

Reduce the steepness of a slope to allow for wave run-up and improve the growing conditions in an area with forested shoreline and high bank height.
Upland management involves capturing rainfall and runoff from impervious surfaces rather than allowing free flow into the waterway. Also, relocating or elevating buildings threatened by flooding or erosion is beneficial. |
