However, <br /> mowing the lawn to the water's edge is contributing to the erosion problem in some areas. The removal of <br /> native, deep-rooted vegetation along the shoreline to create the yard has left this area vulnerable to erosion <br /> due to wave action.Turf grass lacks the deep root structure necessary to hold the bank in place and provides <br /> very low-quality habitat for beneficial insects, birds and amphibians. Your permit application stated a <br /> concern that trees were falling into the lake. Dead trees on the shore and logs lying in the water can be <br /> beneficial as they provide perches for birds and sunning areas for turtles. Preferably,your shore area would <br /> be planted with native vegetation along the shoreline and inland to approximately 15 feet. If you apply <br /> fertilizer and pesticides to your lawn,natural vegetation between your yard and the shore would also provide <br /> some filtering of rain water runoff from your yard,preventing excess fertilizer and pesticides from reaching <br /> the lake. <br /> Enclosed is Permit#2006-0463 authorizing the requested 328 feet of riprap,however,we encourage you to <br /> give consideration to the information in this letter and to the enclosed brochures before deciding on how to <br /> proceed with your project. A well-thought-out lakescaping plan could accomplish your goal of stabilizing <br /> the shoreline while providing much needed habitat and food for wildlife, protecting water quality, and <br /> improving the aesthetic value of the shoreline. <br /> Please read the Conditions of the permit and note that Condition#l4 prohibits work between April 1 and <br /> June 30 in order to minimize the impacts of the project on fish spawning. If you have any questions <br /> concerning this permit, please contact me. <br /> Sincerely, <br /> _ � �- �.��-i-��._ <br /> Julie C.
