The project site is not within the drainage area of a regional stormwater basin or plan. Detention Stormwater Detention is required for the project. Permanent detention Basin# 8 and Basin#9, will be combined as one large basin (Basin# 8) under this project. Two (2)temporary risers shall be installed in the new Basin#8 as a sediment control measures for this project. A new permanent basin will be constructed south of the intersection of Route 649 and Route 606. A temporary riser shall be installed in the new Basin#9 as a sediment control measure for this project Best Management Practices Based on the calculations for the project Drainage Area C+D, the Pollutant Removal Requirement is 27.3 pounds per year, and the required overall BMP pollutant removal efficiency is 12.3 percent. The stormwater management and BMP measures proposed, for Drainage Area C+D, would include the construction of earthen permanent baffles in the stormwater detention basin, Basin#8 and the establishment of a grassed swale in the basin. Based on the calculations for the project Drainage Area I,the Pollutant Removal Requirement is 12.6 pounds per year, and the required overall BMP pollutant removal efficiency is 28.4 percent. The stormwater management and BMP measures proposed, for Drainage Area I, would include the construction of permanent earthen baffles in the new stormwater detention basin, Basin#9 and the establishment of a grassed swale in the basin. The stormwater management and BMP measures proposed for this project are conceptual, and are subject to modification as approved by the Engineering Department. A final stormwater management/BMP plan will be submitted with the final project plans in accordance with Article III l ; of the Water Protection Ordinance (Chapter 19.3 of the Code of Albemarle).
