Martini <br /> Cc: Adam Edwards;Jeremy Barnhart <br /> Subject: Rf: Plan Review#16-3826 for 895 Tonkawa Road <br /> Melanie, <br /> 1 have completed review of the submitted information. Following are my comments for your cnnsideratian: <br /> 1. The drainage patterns are bei�g slightly revised with proposed grad(ng. Under existfng conditions,runoff from <br /> the west side of Lot 1 generally drains northwest onto the adjacent property before flowing west to Lake <br /> Minnetonka,anci the east side drains toward Tonkawa Road before draining north along the road. Runaff from <br /> the west side of Lot 2 drains towards Lake Minnetonka and the east side drains tvward Tonkawa Road,as <br /> well. Undef proposed conditions,runoff frorrz Lot 1 is di�ected to a pipe in the northwest corner of the Lot that <br /> drains to Lake Minnetonka,and the amount of runoff directed north ta the adjacent Lot is minimized. Also,a <br /> swale is proposed on the west side�f lot 2 uphill from the biuff to d(rect water north towards Lot i and an <br /> existing swale that drains down the blufF just south of the�roposed wood stalrway on Lot 1. With proposed <br /> improvements, runoff directed toward the adjacent property north of Lot 1 and over the bluff on Lot 2 should <br /> be greatly reduced. Howe�er,consideration should be given to providing permanent stabilization of the swale <br /> south of the proposed wood stairvvay to llmit potential for erosion due to increased runoff directed here <br /> (especially once a home is constructed on lot 2). <br /> 2. Slltfence should be added along the northeast end of the sauth property line of Lot 2 to limlt potential for <br /> sediment leaving the site. <br /> If you have any questions or comments, please contact me to discuss. <br /> Thanks, <br /> Robert E.Bean,!r,P.E. <br /> LEED Green Assoc. <br /> Bo�ton& Menk, Inc. <br /> P:(952)448-8838, ext 2892 <br /> F:(952j 448-8805 <br /> email: bobbe�bolton-menk.com <br />
