Erosion control measures are required until <br />full soil stabilization has been achieved. <br />Grading/Drainage <br />The gradient within the open water pond will not exceed 5:1 slope. The County Ditch setback of 50' <br />has been met and approved by the County Ditch Inspector. <br />Landscaping <br />Spoils from the wetland excavation will be spread around the new home and then sodded to prevent <br />erosion into the wetland. Erosion Control measures such as silt fence and/or erosion control <br />blankets are required between the wetland and upland areas to prevent erosion into the wetland until <br />all areas are completely stabilized. <br />Recommendation <br />Staff recommends that the Planning Commission recommend approval of the request, as illustrated <br />on drawings dated, with the following conditions: <br />1.

Erosion Control BMP's (i.e. silt fence and/or erosion control blankets) must be <br />installed between the wetland and upland areas prior to excavation and placement of <br />spoils; <br />4. BMP's must be removed following final stabilization of soils; <br />5. Primary septic drain field and secondary sites must be roped off to prevent <br />compaction of soils; <br />6.
