r CMP Part 3A. Environmental Protection Plan 5. Natural drainageways will be favored over artiflcial storm sewers. Storm sewers speed runoff and provide no natural filtration or nutrient assimilation. Storm sewers will only be utilized in local flood prone areas or where there is soil erosion insolvable by natural means. Whenever possible, storm sewer outlets will be directed into marshland or natural drainageways and not directly into the lake. Storm sewer systems will not be considered for new developments or where satisfactory natural drainage systems already e,xist. 6. The wetlands and marshlands of the city will be protected and preserved as wildlife habitats, as unique open spaces, and as the only economically practical method of flood protection and storm water runoff filtration. The Harza Study, the 208 Water quality Management Study, and Orono's Surface Water Management Plan all recommend this approach to permanent water quality management for Lake Minnetonka. In addition, the Orono Plan goes on to identify individual wetlands and marshlands that require protection as part of the City's storm water management program. It is the policy of this plan to effectuate the policies and recommendations of the 1974 Orono Surface Water Management Plan. % 7. Protection of the city’s marshland, wetlands and drainageways shall include protection of adjoining lands and prevention of drainage, filling dredging or wetland's vegetation removal. Ordinances will establish setbacks for all land alteration or construction. Wherever possible, the City will acquire open space and flow age easements for conservation of these lands 8. Protection of lake resources will allow reasonal.^ css, use and enjoyment while preventing overcrowding and excessive encroachment. In conformance with Mn. DNR Shoreland Management regulations for Recreational Development lakes, the City will prohibit overly dense development within 1,000 feet of Lake Mirmetonka. Lake use regulations will be promo.to limit excessive boat density and overuse of sensitive bays. Land use regulations will be developed to provide reasonable control over building density, land alteration and lakeshore encroachment. 9. Lake shorelines will be protected from alteration. Natural vegetation in shoreland areas will be preserved insofar as practical and reasonable in order to retard smface runoff and soil erosion, and to utilize excess nutrients. Clearcutting will be prohibited. In areas of soil or wave action erosion, natxiral stone rip rap shoreline protection will be encouraged.
