woody vegetation, restoration of native vegetation buffers, and combined rip rap and vegetation treatments. Public access for shoreline fishing will be included so these areas will be visible and accessible to the public. Active shoreline erosion and disturbance from boat launching could be eliminated from the Causeway. Enhanced sediment traps could be installed to pre-treat storm water runoff before it is discharged to Lake Minnetonka. The project also meets the objectives of the Minnehaha Creek Watershed Distnct Water Resources Management Plan and is consistent with goals, actions and policies published in the plan, beginning on page 89: Goal To nduca the severity and fnquency of flooding and high water, and Improve the chemical and physical quality of surface water. The project is consistent with Actions 1 .2, and 3 if on-site infiltration basins are installed, it is also consistent with new proposed rules that establish vegetated buffers on Lake Shore. Elimination of trailer-launch boat activity at Minnehaha Creek Headwaters is expected to reduce the frequency and severity of weed buildup at the Outlet Control Structure, thereby increasing the ability of the Minnehaha Creek Watershed District to minimize high water conditions on Lake Minnetonka. Goal 2 - Control temporary sources of sediment resuldng from land development acOvIdea and to Identify, minimize, and correct the effects of sedimentation from erosion-prone and sediment source areas. The project will correct ongoing shoreline erosion on the Gray’s Bay/Wayzata Bay Causeway and will eliminate erosion and sedimentation caused by makeshift boat launching there. Goal 3 -Preserve existing water storage capacity below 100-year flood elevations on all water bodies In the watershed to minimize the frequency and severity of high water. The project is not expected to result in the loss of flood storage capacity on Lake Minnetonka. In addition, elimination of trailer-launch boat activity at Minnehaha Creek Headwaters is expected to reduce the frequency and severity of weed buildup at the Outlet Control Structure, thereby increasing the ability of the Minnehaha Creek Watershed District to minimize high water conditions on Lake Minnetonka. Goal 4 - Preserve the natural appearance and funcdon of shoreline areas and minimize degradation of surface water quality that can result from dredging operations.
