D. Stormwater Management.All development within the Shoreland Overlay District shall be consistent <br /> with the Stormwater Management Plan for the City of Wayzata, May 1988 as may be amended and <br /> the following general and specific standards. <br /> 1. General Standards. <br /> a) When possible, existing natural drainageways, wetlands, and vegetated soil surfaces shall <br /> be used to convey, store, filter, and retain stormwater runoff before discharge to public <br /> waters. <br /> b) Development shall be planned and conducted in a manner that will minimize the extent of <br /> disturbed areas, runoff velocities, erosion potential, and reduce and delay runoff volumes. <br /> Disturbed areas shall be stabilized and protected as soon as possible and facilities or <br /> methods used to retain sediment on the site. <br /> c) When development density, topographic features, and soil and vegetation conditions are <br /> not sufficient to adequately handle stormwater runoff using natural features and vegetation, <br /> various types of constructed facilities such as diversions, settling basins, skimming <br /> devices, dikes, waterways, and ponds may be used. Preference must be given to designs <br /> using surface drainage, vegetation, and infiltration rather than buried pipes and manmade <br /> materials and facilities. <br /> E. Specific Standards. <br /> 1. When constructed facilities are used for stormwater management, documentation shall be <br /> provided by a qualified individual that they are designed and installed consistent with the field <br /> guidelines of the Minnehaha Creek Watershed District. <br /> 2. Newly constructed stormwater outfalls to public waters shall provide for filtering or settling of <br /> suspended solids and skimming of surface debris before discharge. <br />
