We have spoken with Ian McMillan of your office and we believe we have supplied the materials necessary to respond to your request. We will address each point in your letter herein. On March 10, 2008, Jamie Shern of the USACE stated that he would approve the sewer project under a Nationwide Permit 12, and then approve the housing development later under a Nationwide >;ermit 29. The project has logical termini and can be considered a single and complete project. However, jurisdictional area impacts will be considered cumulative when the housing development permit is applied for 2. Our original site plans, depicting jurisdictional area impacts associated with the sewer alignment, were submitted at a scale of 1" = 50'. However, we have submitted additional plans attached to this letter at various scales, with detail sheets at the requested scale or larger. The additional plans are described below. 3. Although we do not have finalized plans for the entire housing subdivision project, we have supplied those elements that are available. a) Cross section detail for culvert crossings are not available at this time. b) The plans for two stormwater retention ponds and other stormwater management practices arP~ included in the enclosed Drawings CS through C8, C19, and E1. c) Plans and profiles for stormwater management devices are enclosed in the enclosed Drawings CS through C8, C19, and E1. Ms. Cyndi Karoly March 21, 2008 Page 2 of 3 EcoScience: a Division of PBS&J d) Stormwater inlets, outfalls, and drainage areas are shown in the enclosed Drawings C7 and C8. e) An inventory of proposed project imperviousness is not available at this time. f) Building envelopes for all lots are not available at this time. Some proposed footprints for townhomes are depicted on Drawing C2. g) Proposed lot layouts are shown in the enclosed Drawings C 1 and C2. h) Detailed drawings of stream impacts throughout the proposed subdivision are not available at this time. A generalized depiction of impacts is shown in Figure 1 and Drawings C2 and C4A. i) Detailed drawings of wetland impacts throughout the proposed subdivision are not available at this time. A generalized depiction of impacts is shown in Figure 1 and Drawings C2 and C4A. j) Detailed drawings of riparian buffer impacts throughout the proposed subdivision are not available at this time. A generalized depiction of impacts is shown in Figure 1 and Drawings C2 and C4A. k) Isolated and non-isolated wetlands, streams, and other waters are shown in the overview in Figure 1. They are also depicted throughout the construction drawings. 1) Riparian buffers are shown in the overview in Figure 1. They are also depicted throughout the construction drawings. m) For diffuse flow provision measures, plans, worksheets, please see Drawings CS and C6. The Town of Wake Forest is the review and approval authority for Stormwater management for the project. Diffuse flow provision worksheets and an Operations and Maintenance Agreement are not required and are not available. Please note that a large impact to Austin Creek and adjacent wetlands is depicted on the construction drawings at the western edge of the proposed development. This roadway crossing is still under review. We hope that this information is sufficient to address your questions. If you need any additional information, please let me know. Thank you for your attention.
