The map shall accurately delineate boundaries of the land to be utilized in carrying out the activity, the location and dimensions of any disturbance to the riparian buffers associated with the activity, and the full extent of the riparian buffers on the land/parcel impacted. Project Information continuation: Please state (typed or printed ink below) why this plan for the activity cannot be practically accomplished, reduced or reconfigured to better minimize disturbance to the riparian buffer, preserve aquatic life and habitat and protect water quality. * Note: Map A.2 impacts include both the sewer & greenway trail given that they are adjacent to each other. We have approximated the impacts for each use. ** Note: Grenway trail width is 10', but the impacts are variable given the grading necessary to install the trail approaches to pedestrian bridge due to the valley shape. The crossings are needed to extend the sewer and trail from upland to upland areas. The crossings were made as close to perpendicular as possible to minimize impacts. A erosion control plan will be approved for the project to include silt fencing and other devices to protect the avoided buffer areas, protect water quality, preserve aquatic life and habitat. A stormwater management plan will also be approved for the project to protect buffers and waters post -construction. Date ,4D/'2' /1-J �j�,o3� �. ►�a�>w.
