Please provide the following information so that we may continue to review your project and prevent return of your application as required by 15A NCAC 2H .0506: Additional Information Requested Application norm: a. Please submit an additional sheet with drainage area information for Drainage Areas # 3 and # 4 having the same information as that given under Section III (Project Information) of the Application Form. This includes the Basin Information as well as the detailed Impervious Surface Area Breakdown for each drainage area. b. The initials under Section VI of the Application Form must be completed. Wet Ponds: a. Flow Elongation Baffles: This office is of the view that the flow elongation baffles in Ponds # 3 and # 4 may not necessarily be cost and treatment effective and therefore recommends their removal. b. Planting plan (Sheet C7.7): (i) Please choose a shrub other than Myrica cerifera for your wet detention ponds, since it is a known nitrogen-fixing plant. (ii) Plant spacing - please clarify your herbaceous plant spacing. Does your 42" average spacing for herbaceous plants refer to "on center" or is it the spacing between plants? If it refers to on center, the planting is too sparse. It is within the recommended range of spacing (18" - 24" on center) if it refers to the spacing between the plants. 401 Oversight/Express Review Permitting Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 Location: 2321 Crabtree Blvd., Raleigh, North Carolina 27604 Phone: 919.733.17661 FAX: 919-733-6893 Internet. http://h2o.enr.state,nc.uslncwetlands/ One No1-thCarolina Natlindif An Equal Opportunity 1 Aitirmalive Action Employer Jamestown Middle School Andrew LaRowe Page 2 of 2 May 28, 2009 Please respond within five (5) days of the date of this letter by sending two (2) copies of the above information and any revisions in writing.
