Please adequately address the following comments for final approval: 1. Please review the Current Design Standards Manual for updated Notes required on plans. httD:// www.albemarle.or2 /uDload/imaL-es /forms center /departments /communitv developm ent/forms /desian standards manual/Albemarle Countv Desian Standards Manual 02- 12- 2010.pdf Notes required for this plan: "General Construction Notes" and "General Construction Notes for Erosion and Sediment Control Plans" 2. FEMA Map updates required per SP201000027. Please send copies for the file. 3. Army Corp, DEQ Approvals required. Please send copies for the file. 4. Plan does not appear to match the SP201000027 plan. The 2- 30" HDPE pipes are missing. County Engineer approval will be required for changes to proposal. Please submit copies of stream analysis "without" 30" pipes for review. B. Mitigation Plan 1. Areas restored or replanted for mitigation must be protected in easements or by maintenance agreements. httD: / /www.albemarle.ora /upload /imaees /forms center /departments /Community Development/for ms/En ineering and WPO Forms/Plan Review - _Stormwater_ Management _BMP_ Facilities _ Maintenance_Agreement.pdf http:// www.albemarle.org/upload/images /forms center /departments /Community Development/for ms/En ing eering_and_WPO_Forms/Plan_Review_- Stormwater Management BMP Facilities Maintenance Agreement Procedures.pdf 2. Please clarify the planting plan. Please show the "unit" locations in each stream buffer planting area. Please note 2 proposed areas do not appear to be within the 100' stream buffer area and will not count towards mitigation. C. Erosion Control Plan 1. Please connect the silt fences along the stream for initial disturbance and foundation excavation. 2. Please show ends of silt fence running up hill until the bottom of the silt fence is higher than the top of the middle of the installation to prevent end -run erosion. Cofferdams may be a better product for the contractor due to the rocky stream environment and can be determined at the pre - construction meeting.
