The low densities and large open space figures are a result of current zoning controls which are for the most more restrictive than the DNR model shoreland regulations and act to preserve the shoreland areas of Wayzata. The significant disparity between lot coverage in residential and commercial areas provides the City an opportunity to utilize residential surplus for further development/redevelopment. Development which proposes to exceed the lot requirements of the Shoreland Overlay District shall be s^^ect to a conditional use pemit and Shoreland Impact Plan, which will emphasize storm water management and quality of runoff. The DNR requirement for impervious surface coverage (25 percent) will be too restrictive to allow for development and redevelopment within some areas of the Shoreland Overlay District. Average .ot coverage for commercial uses indicates that on average, most lots site parfeing is fundamental in this highly developed area. developments are proposed to be allowed to exceed 25 storm 75 percent if structures and practices ?^® ?00 water runoff from directly entering tne lake. percent will be allov'ed with the su-^ittal ^d PP , that Shoreland Impact Plan/:onditional use permit. exceed the Shoreland Ordinance requirements and meet the objectives of the City's Storm Water Manag provide the added physical protection fcr preserving water quality. .fl
