Raleigh, North Carolina 27699 Re: River Run Phases 4 &5 Corps AID # SAW -2009 -01115 DWQ Project # 04-0544,Ver.3 W &R Project #0208o688.o6 Dear Mr. Shaeffer and Ms. Higgins, On behalf of John Weiland Homes, LLC, we are requesting authorization from the USACE to use NWP 29 for 49 if of permanent perennial stream impacts and 221 if of unimportant stream for construction of Phases 4 &5 of the River Run Subdivision. We are also requesting 4o1 authorization for the above mentioned stream impacts, as well as Buffer Authorization for 13,490 sq ft of riparian buffer impacts (Z1: 7,568 sq ft; Z2: 5,922 sq ft). The project is ±14.6 acres in size and is located at the southern terminus of Wake Bluff Drive in the River Run subdivision in Raleigh, Wake County (Latitude: 35.927636 °N; Longitude: - 78.580747 °W)• The project is located in the Neuse River basin and onsite waters drain to the Neuse River. The Water Quality Classification for the Neuse River is WS- IV;NSW and the Stream Index Number is: 27420.7). The cataloging unit for the site is 03020201. Proposed Project The proposed project consists of the construction of Phases 4 &5 of the River Run subdivision, which will consist of 29 lots and associated infrastructure (i.e. roads, utilities, stormwater management, etc.) Please note that this will be the final phases of the River Run subdivision. 1410 Commonwealth Drive I Suite 1011 Wilmington, NC 28403 1 tel: 910.256.9277 1 fax: 910.256.2584 www.withersravene[.com I License No. C -0832 WITHERS II RAVEN EL ENGINEERS I PLANNERS I SURVEYOR5 Proiect Histo The River Run Subdivision was originally permitted in 2004. The Corps issued a NWP 12 & 39 (AID #s 200321366 & 2004420721) for the original River Run subdivision which authorized 181 if of permanent stream impacts and 98 if of temporary stream impacts. DWQ issued a 401 WQC and Buffer Authorization (DWQ Project #04-0544) for the River Run subdivision authorizing 181 if of permanent stream impacts, 98 if of temporary stream impacts and 31,315 sq ft of buffer impacts. The authorizations required 181 if of stream mitigation and 1,740 sq ft of buffer mitigation, which was purchased from EEP. Copies of these permits and mitigation receipt have been provided as an Appendix. River Run Phases 4 &5 (current project) was issued a 401 WQC and Buffer Authorization (DWQ Project #04-0544, Ver.3) in October 2oo9 authorizing 203 if of permanent, perennial stream impacts (181 if previously permitted & 49 if of new impacts), 221 if of permanent impacts to unimportant, intermittent stream impacts (new impacts) and 38,346 sq ft of buffer impacts. The 401 WQC required 49 if of stream mitigation. A copy of the previous 401 WQC for the River Run Phases 4 &5 project has been provided as an Appendix. The Corps issued a NWP 29 in September 2011 (AID# SAW - 2009 - 01115) authorizing 49 if of important perennial stream impacts. The 221 if of unimportant, intermittent stream impacts, which were identified in the PCN, were not included in the permit as they were waived by the Corps and not included in the total cumulative impacts for the River Run subdivision and mitigation was not required for these impacts. It should be noted that the 221 if of intermittent stream consists of a small channel, which is fed by the outfall for the stormwater management system of the development to the south. This section of intermittent stream has very low functional value and the hydrology is controlled entirely by discharges from the adjacent stormwater management system, which is why the Corps waived the impacts /mitigation for this feature. The previous NWP 29 required 98 if of stream mitigation, which was purchased from Forrest Creek Mitigation Bank. A copy of the previous NWP 29 for River Run Phases 4 &5 has been provided as an Appendix. A copy of the mitigation payment receipt has also been provided as an Appendix.

Please note that during the previous 401 WQC review process for River Run Phases 4 &5, DWQ issued a Request for Additional Information, of which Item 6 addressed the issue of why the riparian buffers stopped at Impact Q, and did not extend along the intermittent stream at Impact Y. W &R submitted a response, dated September 18, 2oo9, documenting that a site visit had been previously conducted by NC -DWQ which confirmed that the limits of buffer subjectivity stopped at the origin of Impact Q, and that the intermittent stream (Impact Y) was not subject to buffers. The issuance of the previous Buffer Authorization for the proposed project documents that the intermittent stream (Impact y) was not subject to buffers. The Corps NWP 29 and DWQ 401 WQC and Buffer Authorization expired on March 18, 2012, but are granted an automatic 1 -year extension, making them valid until March 18, 2013. The River Run Phases 4 &5 was previously permitted as a townhome development, and due to the downturn of the economy, the authorized impacts were never completed. As a result of the current real estate market, townhomes are not a desired product in this area of Raleigh and are not currently selling in the general area. Therefore, the site plan was revised to convert the project from a townhome development to a single family residential development. The revision of the design to a single family development resulted in changes to the road design and stormwater management design, which has resulted in a change in the previously approved impacts. The major design change in the road construction will occur at Impact Y. The previous design was for a road crossing in order to provide access to WITHERS RAVENEL Page 3 of 7 ENGINEERS I PLANNERS I SURVEYORS WITHERS II RAVEN EL ENGINEERS I PLANNERS I SURVEYOR5 the uplands on the west side of the stream and for construction of the townhomes on Lots 28 & 29 (old site plans). The design now proposes a cul -de -sac on the eastern side of the stream at Impact Y, which will provide road frontage for construction of Lots 11, 12 & 13 (new site plans). The 221 if of unimportant intermittent stream impacts will still be necessary for construction of single family Lots 11, 12 & 13 rather than the previously approved townhomes. While the NWP 29 and 401 WQC /Buffer Authorization is valid until March 18, 2013, the revisions to the site plan and impacts resulted in a need to request new authorizations for the proposed project. The redesign of the site plan will require the same amount of stream impacts as was previously authorized, but revisions to the stormwater management plan has resulted in changes to the buffer impacts from what was previously authorized for the River Run Phases 4 &5 project. Also, please note that the pedestrian trail and bridge previously authorized at Impact R is no longer required by the City of Raleigh and will not be constructed. Proposed Impacts Stream Impacts The proposed project will result in 49 if of permanent perennial stream impacts and 221 if of unimportant intermittent stream impacts, which is the same as was previously approved. The 49 if of permanent perennial stream impacts will occur from the placement of rip -rap in the channel below the stormwater outfall in order to dissipate energy and prevent erosion, which is the same design and impacts as was previously approved. The previously approved 221 if of unimportant intermittent stream impacts was authorized for construction of the road crossing and construction of townhomes on Lots 28, 29 & 30 (old site plans). The proposed design for Phases 4 &5 will require 221 if of unimportant intermittent stream impacts for construction of the cul -de -sac, as well as construction of single family homes on Lots 11 & 12. Since the previous NWP 29 and 401 WQC authorized the 221 if of unimportant for the construction of a road and townhouses, it is anticipated that the proposed 221 if of unimportant intermittent stream impacts for the construction of the cul -de -sac and lots 11, 12 and 13 will be an issue. Furthermore, since the Corps waived the 221 if of unimportant intermittent stream impacts in the permitted stream impacts in the previously issued NWP 29, it is also assumed that these proposed 221 if of unimportant intermittent stream impacts will also be waived and not counted towards the 300 if of cumulative stream impacts allowed under a NWP. Please note that Impact R consists of an aerial sewer crossing and stream impacts for installation of the sewer crossing is not required. WITHERS RAVENEL Page 4 of 7 ENGINEERS I PLANNERS I SURVEYORS WITHERS II RAVEN EL ENGINEERS I PLANNERS I SURVEYOR5 Buffer Impacts The proposed project will result in 13, 490 sq ft of buffer impacts (z1: 7,568 sq ft; Z2: 5,922 sq ft). Buffer impacts at Impacts R & T will occur from installation of a sewer crossing and establishment of a sewer easement. Buffer impacts at Impacts V, W and X will occur from construction of bypass channels. Buffer impacts at Impact Y will occur from construction of the cul -de -sac. Due to the steep grades and depth of the topographic crenulation at this impact, the buffers will be impacted from fill necessary to return road fill to natural grade (see Sheet 2A). Please note that the buffer impacts associated with Impact Y are less than was previously approved for the previously designed road crossing. Avoidance and Minimization Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands and "waters" could be minimized. The previously approved project consisted of a townhome development. As a result of the current real estate market, townhome developments are not a desirable product in this area of Raleigh and are not currently selling in the general area. Therefore, the site plan was redesigned to be a single family residential development, which is a much more desirable product. The redesign of the site plan resulted in the elimination of the road crossing at Impact Y, and was replaced with a cul -de -sac. The location of the cul -de -sac was determined by several factors. The proposed location of the cul -de -sac provides the minimum road frontage for Lots 12 & 13 per the zoning requirements. If the cul -de -sac was relocated farther to the east to attempt to reduce impacts, Lots 12 & 13 would not have the 20' of road frontage required, which is the minimum frontage allowed by the City of Raleigh zoning requirements, and Lots 12 & 13 would not be developable. The River Run property was purchased when real estate values were much higher. The project's profitability has already been greatly reduced as a result of the change from a high density townhome development to a much lower density single family development. Therefore, the loss of Lots 12 & 13 would greatly impact an already diminished profit margin, potentially rendering the project financially unfeasible. Therefore, impacts at Impact Y have been minimized to the greatest extent possible while maintaining a feasible project. As was previously discussed, the cul -de -sac has been designed to extend just far enough to provide the minimum lot road frontage required by the zoning requirements to make Lots 12 WITHERS RAVENEL Page 5 of 7 ENGINEERS I PLANNERS I SURVEYORS WITHERS II RAVEN EL ENGINEERS I PLANNERS I SURVEYOR5 & 13. If the cul -de -sac would have been designed to extend farther west to provide more than the 20' minimum road frontage on Lots 12 & 13, the road would have exceeded the 150 If threshold for a 37.5' cul -de -sac radius for emergency vehicle turn - around, and would have been required to have a 48' cul -de -sac radius. The expansion of the cul -de -sac from a 37.5' radius to a 48' radius would have resulted in a significant increase in both buffer and stream impacts. Therefore, impacts have been minimized to the greatest extent practical while maintaining a feasible project. Impacts from the cul -de -sac at Impact Q were also minimized through the use of a retaining wall to stabilize road fill. Stream impacts were avoided at Impact R through the use of an aerial sewer crossing to cross the stream. Mitigation Stream Mitigation The previously issued NWP 29 and 401 WQC for the River Run Phases 4 &5 project required 98 if of stream mitigation to compensate for the 49 if of permanent perennial stream impacts, which was purchased from Forrest Creek Mitigation Bank. A copy of the mitigation receipt has been provided as an Appendix. Mitigation was not required for the 221 if of unimportant intermittent stream impacts. Since the currently proposed design for the River Run Phases 4 &5 project proposes the exact same stream impacts was previously permitted and mitigated for, there is no additional stream mitigation proposed. Buffer Mitigation The proposed cul -de -sac at Impact Y is identified as "Allowable with Mitigation" in the NRB Table of Uses, mitigation will be provided. Therefore, to mitigate for the proposed 6,979 sq ft of buffer impacts proposed for Impact Y, the applicant proposes to purchase 16,048.5 sq ft of riparian buffer mitigation from Wildlands Neuse Bank: Little River Farm. A copy of the Letter of Reservation from Wildlands has been provided as an Appendix. Stormwater Management Plan The stormwater management plan consists of three level spreader /vegetated filter strip systems. The stormwater management plan has been preliminarily approved by the City of Raleigh, and will receive final approval upon issuance of the 404/4o1 authorization. Upon issuance of the final stormwater management approval, a copy will be provided to NC -DWQ.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands and "waters" could be minimized. The previously approved project consisted of a townhome development. As a result of the current real estate market, townhome developments are not a desirable product in this area of Raleigh and are not currently selling in the general area. Therefore, the site plan was redesigned to be a single family residential development, which is a much more desirable product. The redesign of the site plan resulted in the elimination of the road crossing at Impact Y, and was replaced with a cul -de -sac. The location of the cul -de -sac was determined by several factors. The proposed location of the cul -de -sac provides the minimum road frontage for Lots 12 & 13 per the zoning requirements. If the cul -de -sac was relocated farther to the east to attempt to reduce impacts, Lots 12 & 13 would not have the 20' of road frontage required, which is the minimum frontage allowed by the City of Raleigh zoning requirements, and Lots 12 & 13 would not be developable. The River Run property was purchased when real estate values were much higher. The project's profitability has already been greatly reduced as a result of the change from a high density townhome development to a much lower density single family development. Therefore, the loss of Lots 12 & 13 would greatly impact an already diminished profit margin, potentially rendering the project financially unfeasible. Therefore, impacts at Impact Y have been minimized to the greatest extent possible while maintaining a feasible project. As was previously discussed, the cul -de -sac has been designed to extend just far enough to provide the minimum lot road frontage required by the zoning requirements to make Lots 12 & 13. If the cul -de -sac would have been designed to extend farther west to provide more than the 20' minimum road frontage on Lots 12 & 13, the road would have exceeded the 150 If threshold for a 37.5' cul -de -sac radius for emergency vehicle turn - around, and would have been required to have a 48' cul -de- sac radius. The expansion of the cul -de -sac from a 37.5' radius to a 48' radius would have resulted in a significant increase in both buffer and stream impacts. Therefore, impacts have been minimized to the greatest extent practical while maintaining a feasible project. Impacts from the cul -de -sac at Impact Q were also minimized through the use of a retaining wall to stabilize road fill. Stream impacts were avoided at Impact R through the use of an aerial sewer crossing to cross the stream.

Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Construction techniques used to minimze impacts included headwalls and steeper fill slopes. Also, an aerial sewer crossing will be used at Impact R to avoid stream impacts at this location. 2.

At this time, the DWQ has not approved the use of sediment and erosion control devices in Zone 1 anywhere on this project. Sediment and erosion control • John Weiland Homes Page 3 of 4 4/22/04 devices shall be allowed in Zone 2 of the buffers provided that Zone 1 is not compromised and that discharge is released as diffuse flow. 6. The outside buffer, wetland or water boundary as well as along the construction corridor within these boundaries approved under this Certification shall be clearly marked by orange fabric fencing for the areas that have been approved to infringe within the buffer, wetland or water prior to any land disturbing activities to ensure compliance with 15A NCAC 2B .0250. 7. This Certification does not authorize the discharge of waste rock and dirt into the stream or riparian zone except for permitted areas associated with culvert conditions. 8. The project shall comply with 15A NCAC 2H .0219(i)(2)(G) and all other State, Federal and local sewer system regulations. 9. Stormwater management structures shall be constructed and maintained according to the plans submitted in the March 19, 2004 application. 10. All stormwater shall be directed as diffuse flow at non - erosive velocities through the protected stream buffers and will not re- concentrate before discharging into the stream as identified within 15A NCAC 2B .0233(5). 11. During the construction of the project, staging of equipment of any kind is not permitted in waters of the State, or protected riparian buffers. 12. The dimension, pattern, and profile of the stream, above and below the crossing, should not be modified by widening the stream channel or reducing the stream depth. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 13. Where practicable, culverts that are less than 48 -inch in diameter should be buried to a depth equal to or greater than 20% of their size to allow for aquatic life passage. Culverts that are 48 -inch diameter or larger should be buried at least 12 inches below the stream bottom to allow natural stream bottom material to become established in the culvert following installation and to provide aquatic life passage during periods of low flow. This may require increasing the size of the culvert to meet flow conveyance requirements. All waters must flow through without freefalling or damming on either end of the culverts during low flow conditions, to maintain aquatic life and/or fish passage. 14. Any riprap used must not interfere with aquatic life passage during low flow conditions. 15. If concrete is used, work must be accomplished so the wet concrete does not contact the stream water. This will lessen the chance of altering the stream's water chemistry and causing a fish kill. 16. Heavy equipment must be operated from the banks rather than in the stream channel in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream. 17. The presence of equipment in the channels must be minimized. Under no circumstances must rock, sand or other materials be dredged from the wetted stream channel under this authorization, except in the immediate vicinity of the culverts. 18. All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 19. Riparian vegetation must be reestablished within the construction limits of the project by the end of the growing season following completion of construction. All protected riparian buffers impacted by the placement of temporary fill or clearing activities shall be restored to the preconstruction contours and revegetated with native woody species upon completion of the project construction. f John Weiland Homes Page 4 of 4 4/22/04 20. The applicant and /or authorized agent shall contact the DWQ Express Review Program in writing at the letterhead address within 10 days of the commencement of construction. 21. Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer Rules and any subsequent modifications, the applicant is required to return the attached certificate of completion to the 401 /Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699- 1650.
