ENVIRONMENT JUNE, 1980 <br />6. <br />7. <br />8. <br />9. <br />So. <br />P^CTICAL ^THOD OF FLOOD PROTECTION AND STORM WATER RUNOFF FILTRATION. <br />The Harza Study, the 208 Water Quality Management Study, and Orono's <br />Surface Water Management Plan all recommend this approach to permanent <br />water qualxty management for Lake Minnetonka. In addition, the Orono <br />Plan goes on to identify individual wetlands and marshlands that <br />require protection as part of the City's storm water management program. <br />1- IS the policy of this plan to effectuate the policies and recommen­ <br />dations of the 1974 Orono Surface Water Management plan. <br />MARSHLAND, WETLANDS AND DRAINAGEWAYS SHALL <br />INCLUDE PROTECTION OF ADJOINING LANDS AND PREVENTION OF DRAINAGE <br />FILLING, DREDGING OR WETLAND'S VEGETATION REMOVAL. Ordinances will <br />establish setbacks for all land alteration or construction. Wherever <br />possible, the City will acquire open space and flowage easements for <br />conservation of these lands. <br />lake resources will ALLOW REASONABLE ACCESS, USE AND <br />ENJOYMENT WHILE PREVENTING OVERCROWDING AND EXCESSIVE ENCROACHMENT. <br />In conformance with Mn. DNR Shoreline Management regulations for <br />recreational development lakes, the City will prohibit overly dense <br />development within 1,000 feet of Lake Minnetonka. Lake use regulations <br />will be promoted to limit excessive boat density and overuse of sensitive <br />bays. Land use regulations will be developed to provide reasonable <br />control over building density, land alteration and lakeshore encroachment. <br />^E SHORELINES WILL BE PROTECTED FROM ALTERATION. Natural vegetation <br />in shoreland areas will be preserved insofar as practical and reasonable <br />in order to retard surface runoff and soil erosion, and to utilize <br />excess nutrients. Clearcutting will be prohibited. in areas of soil <br />or wave action erosion, natural stone rip rap shoreline protection will <br />be encouraged. <br />WILL BE DISCOURAGED BECAUSE OF ADVERSE SHORT-TERM <br />^D LONG-TERM EFFECTS ON WATER QUALITY. Dredging of lake beds releases <br />large amounts of otherwise trapped nutrients and silt which adversely <br />affects water quality for long periods of time. Dredging of new <br />channels or inlets will not be approved to provide riparian access <br />where none existed naturally. Dredging will be permitted in limited <br />circumstances only where absolutely necessary to maintain existing <br />natural riparian access permanently lost by something beyond the <br />control of the landowner. Periodic low water conditions or the owner's <br />desire for deeper draft watercraft are not sufficient reasons for <br />disrupting sensitive lake beds. <br />CMP 3-20
