p^yTRQNMENT JU>IE, 1980 6. THE WETLANDS AND MARSHLANDS 0? THE CITY WILL BE PROTECTED AND PRESERVE! AS WILDLIFE HABITATS, AS UNIQUE OPEN SPACES, AND AS THE ONLY ECONOMICAI PRACTICAL METHOD OF FLOOD PROTECTION AND STORM WATER RUNOFF FILTRATION. The Harza Study, the 208 Water Quality Manageaent Study, and Orono’s Surface Water Hanagenent Plan all recoaaend this approach to peraanent water quality aanageaent for Lake Minnetonka. In addition, the Orono plan goes on to identify individual wetlands and carshlands that require protection as part of the City's storn water aanageaent progra: It is the policy of this plan to effectuate the policies and recoaaen- dations of the 1974 Orono Surface Water Manageaent Plan. 7. PROTECTION OF THE CITY'S MARSHLAND, WETL-ANDS AND DP^AINAGEW.AYS SH.ALL INCLUDE PROTECTION OF ADJOINING LANDS AND PREVENTION OF DRAINAGE, FILLING, DREDGING OR WETIAND'S VEGETATION REMOVAL. Ordinances will establish setbacks for all land alteration or c'onstruction. Wherever possible, the City will acquire open space and flowage easeaents for conservation of these lands. 8. PROTECTION OF LAKE PEISOURCES WILL ALLOW REASON.ABLE ACCESS, USE AND ENJOYMENT WHILE PREVENTING OVERCROVrDING AND EXCESSIVE ENCROACHMENT. In conforaance with Mn. DNR Shoreline Hanagenent regulations for recreational developaent lakes, the City will prohibit overly dense developaent within 1,000 feet of Lake Minnetonka. Lake use regulation will be proaoted to liait excessive boat density and overuse of sens bays. Land use regulations will be developed to provide reasonable control over building density, land alteration and lakcshore encroachn 9. LAKE SHORELINES WILL BE PROTECTED FROM ALTER.ATION. Natural vegetatior in shoreland areas will be preserved insofar as practical and reasona in order to retard surface runoff and soil erosion, and to utilize excess nutrients. Clearcutting will be prohibited. In areas-of soi .• or wave action erosion, natural stone rip rap shoreline protection w be encouraged. 10. LAKE BED ALTERATIONS WILL BE DISCOUR.AGED BECAUSE OF ADVERSE SHORT-TER-’ AND LONG-TERM EFFECTS ON WATER QUALITY. Dredging of lake beds releas* large aaounts of otherwise trapped nutrients and silt which adverse y affects water quality for long periods of tine. Dredging of new channels or inlets will not be app.roved to provide riparian access where none existed naturally. Dredging will be permitted in lini^-e circunstances only where absolutely necessary to naintain existing natural riparian access pernanently lost by soaething beyond the control of the landowner. Periodic low water conditions or the owne- desire for deeper draft watercraft are not sufficient reasons fo- disrupting sensitive lake beds. CMP 3-20
