Compliance with <br /> permit specification would not provide enough additional protection or <br /> control to warrant re-working of the project. <br /> The statement by the contractor verified compaction and the stability <br /> of the berm. <br /> The system will provide a filtered, low velocity, run-off into the marsh, <br /> minimizing siltation and erosion. Ponding may occur on the property <br /> inside of the berm with the event of abnormally high water level in <br /> the marsh, but, this water would again filter out as the marsh level <br /> subsided. The ponding would occur even if the system had not been con- <br /> structed. Therefore, safe and healthful conditions will not be sub- <br /> stantially changed. <br /> CONCLUSION: <br /> 1. Project as constructed meets the intent of the soil erosion plan <br /> and will not result in substantial detriment to navigable waters by <br /> erosion, sedimentation, impairment of fish or aquatic life or safe <br /> and healthful conditions. <br /> 2. The condition of future review in the event of improvements or con- <br /> struction will provide the opportunity to re-design the soil ero- <br /> sion control system to provide adequate protection of the marsh. <br /> Motion carried. <br /> Motion by Schwahn, second by Kruschke to adjourne; motion carried. <br /> Meeting adjourned at 9: 15 p.m. <br /> RECE Vr <br /> Phyllis Schwahn, <br /> Secretary <br /> OCT 2_ 7 1981 <br /> Dane County Ceti <br /> Minutes filed with Dane County clerk ' Office on <br /> O <br />
