CMP Part 3A. Enviroomeatal Prnt*«?ri«ii pjao 5. 6. 7. 8. 9. Natural drainageways will be favored over artUicial storm sewers. Stoim seweirs speed ninoff and provide no natural filtration or nutrient assimilation. Storm sewers will only be utilized in lofal 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 exist. 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 runoffflltration. The Harza Study, the 208 Water quality Management Study, and Orono's Surface Water Management Plan al 1 recommend this approach to permanent water quality management for L^e Mirmetonka. In addition, the Orono Plan goes on to identify individi^ 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. 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 flowage easements for conservation of these lands. Protection of lake resources will allow reasonable access, 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 ofLake Mirmetonka. Lake use regulations will be promoted 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 Lake shorelines will be protected from alteration. Natural vegetation in shoreland areas will be preserved insofar as pr-xtical and reasonable 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 prot will be encouraged. CKy of Orooo COaoiaalty Maasgenicat Plaa fiiC*3A42
