Normally this <br />level of useage would require access on a publicly maintained <br />street, not via a private outlot. <br />Lake Use <br />The Ringer property includes about 700 ft of shoreline on Dickey <br />Lake, which is about 1/6 of the total shoreline. Seven residences <br />plus 2 other vacant tracts also abut the shore. <br />Zoning District lake frontage requirements are 200 ft/residence. <br />The existing residences average 250-300 ft of shoreline each, <br />although 2 parcels have only 50 ft each. <br />The Ringer property if residentially developed would therefore <br />likely have at most 3 riparian lots, each of which would be al­ <br />lowed 1 dock and up to 4 boats (LMCD Lake Minnetonka spec's). <br />Parkview lake use should this be limited to not more than the <br />same level of useage, which could be up to 12 boats. <br />Dickey's Lake is entirely private. There is no existing public <br />access even though it is classified as public waters. As part <br />of the subdivision, we should carefully consider platting of a <br />fire lane or other limited access trail. . ! <br />vf <br />-....S'C!. -S. » <br />aSamm^ai
