A three foot (3') minimum separation is required from the bottom of the infiltration basin to the <br />seasonally high groundwater. Based on the submitted soil borings, the seasonal high groundwater <br />was observed at approximately two feet (2') below existing grade. <br />5. The City may require the Applicant to submit an alternative design for this site. The final <br />development plan alternative will need to demonstrate that floodplain fill, disturbance within the 75 <br />foot shoreland impact zone, and encroachment of the building structure in the 150 structure setback <br />is minimized. <br />6. The wetland delineation line is incorrectly labeled as the Ordinary High Water Elevation. Revise <br />the wetland delineation call -out on the Plans. In addition, include the Ordinary High Water <br />Elevation (drawn at an elevation of 883.7) on the Plan and label. Revise the 75 foot shoreland <br />impact zone to be measured from the ordinary high water elevation instead of the wetland <br />delineation as currently drawn. As stated in comment 2 above, the 150 foot structure must also be <br />shown on the Plans. <br />12/26/07 This item has been addressed. <br />The following are minor plan, calculations, and drafting corrections that must be addressed prior to final <br />approval: <br />1. Label Rough Grouse Street on the plan. <br />12/26/07 This item has been addressed. <br />2. Show the location of the rock construction entrance and inlet protection on the Grading Plan. <br />12/11/07 The erosion control notes on Sheet 3 indicate that temporary erosion control is to be placed around <br />storm drain structures during construction. Show the location of the inlet protection on the plan. <br />12/26/07 This item has been addressed. <br />3. Include a silt fence detail and inlet protection detail on the Plan. <br />12/26/07 This item has been addressed. <br />4. Include a note on the Plans indicating that all adjacent streets must be inspected daily and swept <br />clean of sediment tracked from the site. <br />12/26/07 This item has been addressed. <br />
