The North Carolina Department of Transportation (NCDOT) proposes to modify the construction plans for the subject project. The purpose of this letter is to request a modification to the Department of the Army Individual Permit, as well as to the 401 Water Quality Certification and Neuse River Buffer Certification from the NC Division of Water Quality. The revised sheets of the original permit drawings are attached. Revisions were made to the permit drawings in order to be consistent with the construction plans. Changes include expansion and reduction of construction areas, ~ ~, additions of preformed scour holes and extended dry detention basins to absorb sediments ~' ~-' ' and decrease water velocit c-, - Y• r~-~ r"~, ~ The proposed project will result in 0.72 acres of fill in wetlands, 0.05 acres of excavation `-~-~' - in wetlands, 0.02 acres of mechanized clearing in wetlands, and 1,386 linear feet of stream impacts. Onsite stream mitigation totals 3841inear feet. Buffer impacts are 17,668 ft` of allowable impacts and 147,666 ft2 of mitigable impacts. Onsite buffer mitigation totals 15,972 ft2. There will be an increase of .009 acres of excavation in wetlands, .008 MAILING ADDRESS: TELEPHONE: 919-733-3141 LOCATION: NC DEPARTMENT OF TRANSPORTATION FAX: 919-733-9794 TRANSPORTATION BUILDING PROJECT DEVELOPMENT AND ENVIRONMENTAL ANALYSIS 'I SOUTH WILMINGTON STREET 1548 MAIL SERVICE CENTER WEBSITE: ININI't! DOH.DOT.STATE.NC.US RALEIGH NC RALEIGH NC 27699-1548 acres of mechanized clearing in wetlands, no increase in impacts to jurisdictional streams and an increase 10,767 ft2 of Neuse Buffer impacts. A detailed description of the changes at each site is presented in this application. The revised design does not compromise NCDOT's compliance with the existing permit conditions. Mitigation will be provided by WRP. The new impact sites have been evaluated for compliance with the avoidance/minimization criteria and are in compliance with all previous Individual Permit factors, including the following: • Protected Species, • Cultural Resources, • Aquatic Life passage, • FEMA compliance, and • Utilities. In a~May 23, 2001.1et~er from Ron Ferrell, WRP Program Manager, the WRP commited to providing the NCDOT mitigation for the impacts associated with this project. The NCDOT proposes to pay WRP $19,032 for non-riverine wetland impacts (at $12,000 per :N• -~ •,. ' ; acre•of wet~and'h~itigfition required at a 2:1 ratio), $250,500 for stream impacts (at $125 '"' ~ ~ per foot of stream mitigation at a 2:1 ratio), and $329,254 for stream buffer impacts (at $41,625 per acre of stream buffer mitigation required at the 3:1 ratio for Zone 1 impacts and 1.5:1 for Zone 2 impacts less the onsite buffer replacement) for compensatory mitigation in Section B before construction begins. REVISIONS RESULTING IN JURISDICTIONAL IMPACT CHANGES TO WATERS OF THE US Site 3, Sheet 15 of 26 Station -Y1- 18+10 to 18+80 On the west side of existing US 1, an energy dissipater has been added to the plans. The energy dissipater will decrease the erosion potential at this site. An energy dissipater will be used instead of a level spreader due to the steep topography in the area and to minimize impacts to the wetland. This will result in an increase of excavation and mechanized clearing in wetlands. Impact change: increase of < 0.009 acres of excavation in wetlands increase of <0.008 acres of mechanized clearing REVISIONS RESULTING IN NO CHANGES IN IMPACTS TO JURISDICTIONAL WATERS OF THE US Site 1, Sheet 4 of 26 Station -Y2- 11+00 In order to absorb sediments and decrease water velocities, a preformed scour hole was added on the west side of Retail Drive. Two Cross Sectional Pipes will flow directly into the re-enforced concrete box culvert: one to the north of NC 98 and one to the south at Station -L- 32+40 in order to prevent outlet scour. Impact change: none 2 Site 3, Sheet 14 of 26 Station -Y 1- 18+50 In order to absorb sediments and decrease water velocity, a preformed scour hole was added at Station -Y1- 18+50, on the west side of US 1.

Impact change: Mitigable buffer impacts increase of 1,458 ft2. Site 3, Sheet 6 of 20 Station -Y1- 16+80 to 19+00 A cross sectional pipe was added at Station -L- 17+70 and placed out of the Buffer Zone 1 of Richland Creek. The impacts to the buffer of the Unnamed Tributary to Richland Creek that will occur due to boring and jacking of two steel pipes that were not accounted for in the original application and are now accounted for. Impact change: Mitigable buffer impacts increase of 5,395 ftZ. Site 4, Sheet 9 of 20 Station -Y3- 10+84R to 11+81R In order to minimize buffer impacts the construction area has been reduced. The UT located north of Station 37+00 is a non jurisdictional stream. Impact change: Mitigable buffer impacts decrease of 2,631 ft2 Site 4, Sheet 7 and 8 of 20 Station -L- 38+24.5 to 39+44.5 On the original permit application the width of the bridge was used in calculating the amount of impacts to the buffer. However, impacts from construction equipment will ~_ occur within the Right-of Way, therefore Ri t-of Wa width is now used to calculate l~ Y impacts to buffers. Impact change: Buffer impact increase of 7,735 ft2. Site 5, Sheet 10 of 20 Station -L- 47+70 The area of buffers has increased to enable access for the sewer line easement in the south east and north east quadrant.

The proposed channel will be 117m (384') in length starting left of - Y2- Station 10+40 at the inlet of the proposed 2 @ 2.Im x 1.8m (2 @ 7'x 6') RCBC and continue upstream to left -Y2- Station 11+25. The proposed channel is designed according to "Natural Channel" design principles proposed by Dave Rosgen. This unnamed tributary to Richland Creek drains 85 hectares (210 acres) in northern Wake County. Existing and future land uses within the drainage basin are predominantly low to medium density residential with commercial along the major roadway corridors. Currently, there is a large commercial development under construction dire.ctiy upstream of this proposed design. A review of plans for the development indicates that stormwater detention basins will be constructed to treat and control runoff from the site. There is no hydraulic data available on this stream. Discharges were estimated using procedures outlined in USGS Water-Resources Report 96-4084, Estimation of Flood-Frequency Characteristics of Small Urban Watersheds in North Carolina. EXISTING STREAM A 11'1.6m (386') section of the existing stream was surveyed in detail to determine morphological characteristics. Those characteristics include bankfull discharge, width, depth and area. This section of stream was chosen because it will be a portion lost due to the construction of -Y2-. Based on the field survey data gathered, this stream reach was classified as an E4 stream.. The bed material. for this reach was found to be a medium sand with gravel and cobbles. The HEC- RAS computer model was used to determine the hydraulic characteristics of the stream such as velocity, shear stress and stream power. Shcet~ of REFERENCE STREAM Since the NC Stream Restoration Institute does not currently have regional curves or equations for urban areas within the piedmont region, the Existing Stream will also be the Reference Reach. Design and morphological data for the Existing/Reference and Proposed streams are shown in the "Morphological Measurement Table". PROPOSED CHANNEL The proposed stream was designed to have an E4 classification retaining the bankfull characteristics of the existing/reference stream. The gradient for the proposed stream is controlled upstream by the tie to the existing channel and downstream by the invert of the proposed RCBC. To facilitate formation of a natural streambed through the RCBC, the upstream and downstream inverts will be buried a minimum of 0.3m (1.0'). Additionally, a 0.6m (2.0') concrete sill will be placed in the inlet of the right RCBC barrel to restrict normal flows to one barrel at~d maintain a relatively normal depth of flow through the structure. Proposed stream stabilization is shown on the attached detail sheet. It is anticipated that the stream banks will be planted with native trees and shrubs above bankfull depth. To aid in stability and reduce stream gradient, cross vane rock weirs with O.15m (0.5') channel drops will be placed downstream of all meanders. Along the outside of the bends, root wads will be placed and coir fiber mat will line both stream banks. The stream bottom will match the characteristics of the existing channel. - SEDIMENT TRANSPORT ANALYSIS The proposed stream has a bankfull stream power of 1.91 Ib/ft-s and a shear stress of 0.591b/ft'` as compared to 6.26 Ib/ft-s and 1.33 lb/ft2 for the existing stream. These reduced values indicate that the proposed stream will be more stable than the existing stream and reduce bed and bank degradation.
