Lake Minnetonka shoreline. For situations where an existing house is removed and replaced, the new house is normally required to be in conformance to the zoning regulations for structural coverage and impervious surface limitations. This can result in a reduction of impervious surface on the property or impervious surfaces being moved further from the lakeshore. In addition to replacement homes on the lakeshore, there were many more lakeshore remodeling projects. For house remodeling projects the City's policy is to move toward closer adherence to the zoning regulations which may result in less impervious surface and impervious surface being moved further from the lakeshore. Erosion and drainage problems are also corrected during housing redevelopment projects. In summary Orono's stringent zoning requirements continue to be an effective Best Management Practice for storm water runoff management. The City continued street sweeping,recycling,spring cleanup,and yard waste collection programs to reduce illicit discharges to the storm water system. Two existing neighborhoods were provided sanitary sewer service to eliminate non conforming septic systems.
