As more and <br /> more natural shoreline is replaced with constructed shoreline, little habitat remains for a balanced eco <br /> system. The shoreline is a transitional zone between a lake and upland area and this area is an integral part <br /> of a lake's ecosystem in that it sustains both fish and wildlife. A natural shoreline consists of plants and <br /> irregular surfaces that provide habitat,refuge, and food for insects,birds,amphibians, fish, and other <br /> wildlife. Plants also provide filtration of runoff and make your yard less attractive to geese. A constructed, <br /> or hard armored shoreline degrades the quality of the ecosystem. We encourage you to incorporate the <br /> following features into your project that will provide protection from erosion as well as create habitat: <br /> • Turf grass lacks the deep root structure necessary to hold the soil in place. This is evidenced at your <br /> property by the erosion that is occurring where the lawn and riprap meet. Plant deep-rooted native <br /> vegetation within and above the ripra�this will soften the effects of rock armor alone and will <br /> provide a buffer to hold soil in place and stop erosion. <br /> • Riprap that is placed loosely will provide more surface area for increased dissipation of wave <br /> energy than would a smooth, even surface. Loosely placed riprap is flexible so that its effectiveness <br /> is not impaired by slight movement from settlement or impacts from freezing and thawing cycles, <br /> ice or wave action. The existing riprap at your site is loosely placed and we reconunend maintaining <br /> this characteristic. <br /> Enclosed is Permit#2007-0248 authorizing the requested repair of 300 feet of nprap.Please read the Conditions <br /> of the permit. If you have any questions concerning this permit,please contact me. <br /> Sincerely, <br /> r* � �, <br /> .��`"-'�----�_ C � 1�_�--r--r:_r___ <br /> , ��,��"'Julie C.
