The Harza Study, the 208 Hater Quality Management Study, and Orono's surface water Management Plan all recommend this approach to permanent quality management for Lake Minnetonka. In addition, the Orono Ian goes on to identify individual wetlands and marshlands that squire protection as part of the City's storm water management prograr.. It is the policy of this plan to effectuate the policies and recommen dations of the 1974 Orono Surface Water Management Plan. PROTECTION OF THE CITY'S MARSHLAND, WETLANDS AND DRAINAGEWAYS SHALL INCLUDE PROTECTION OF ADJOINING LANDS AND PREVENTION OF DRAIN.AGE, FILLING, DREDGING OR WETLAND'S VEGETATION REMOVAL. Ordinances will establish setbacks for all land alteration or construction.

Natural vegetation^ in shoreland areas will be preserved insofar as practical and reasonab-e in order to retard surface runoff and soil erosion, and to utilize excess nutrients. Clearcutting will be prohibited. In areas-of soil^^ • or wave action erosion,' natural stone rip rap shoreline protection wil- be encouraged. . LAKE BED ALTERATIONS WILL BE DISCOURAGED BECAUSE OF ADVERSE SKORT-TER.H AND LONG-TERM EFFECTS ON WATER QUALITY. Dredging of lake beds releases large amounts of otherwise trapped nutrients and silt which adversely affects water quality for long periods of tine. Dredging of new chaxvnels or inlets will not be approved to provide riparian access where none existed naturally. Dredging will be permitted in limited circumstances only where absolutely necessary to maintain existing natural riparian access permanently lost by something beyond the ^ control of the landowner. Periodic low water conditions or the owner s desire for deeper draft watercraft are not sufficient reasons for disrupting sensitive lake beds. CMP 3-20
