We are also requesting a 401 WQC for the above referenced impacts, as well as a Riparian Buffer Authorization from NCDWR for 13,578 sf of permanent riparian buffer impacts (Zone 1: 8254 sf; Zone 2: 5324 sf). The project is ±12.4 acres in size and is located at 3803 Holly Lane in Raleigh, Wake County (Latitude: 35.833294°N; Longitude:-78.683321°W). The project consists of the following seven parcels: • Wake Co. PIN: 0795386748 - ±2.30 ac • Wake Co. PIN: 0795388982 - ±1.83 ac • Wake Co. PIN: 0795388580 - ±2.20 ac • Wake Co.

PIN: 0795483460 - ±1.60 ac The project is located in the Neuse River basin (HUC: 03020201) and onsite waters drain to Crabtree Creek (Stream Index: 27-33-(10); WQC: C;NSW). Proposed Project The purpose of the proposed project is to construct a residential townhome subdivision to meet the need for residential housing in Raleigh. The proposed project consists of construction of an 88-unit townhome subdivision and associated infrastructure (roads, utilities, stormwater management, etc.). 219 Station Road I Suite 1011 Wilmington, NC 28405 t: 910.622.0122 www.withersravenel.com I License No. C-0832 Asheville I Cary Greensboro I Pittsboro I Raleigh I Wilmington Holly Lane Subdivision - NWP 3 & 13 PCN �: WithersRavene l Our People. Your Success. The City of Raleigh is requiring Holly Lane to be improved from an existing gravel driveway within a public ROW to a paved two-lane road. The improvements to Holly Lane are necessary both for the construction of the stormwater management pond as well as to meet City of Raleigh requirements for site plan approval. The improvements to the existing Holly Lane requires the replacement of the existing dual 36-inch RCP culverts, which are undersized and failing, with three box culverts consisting of a 10-ft x 10-ft box culvert to carry base flow, and two 10-ft x 8-ft box culverts which will carry high flow only. The significant increase in the size of the culverts is based on the drainage study which determined the size and number of box culverts based on the modeling for conveyance during high flows. In the existing condition, the dual 26-inch culverts are undersized, and result in significant backwater and overtopping of the road during heavy rain events. The head created by the backwaters and overtopping of the road has led to significant erosion and undercutting of the existing culverts which has resulted in the failure and collapse of the culverts. The three box culverts have been designed with the 10-ft x 10-ft box culvert carrying the base flow, with the two 10-ft x 8-ft box culverts being installed at a higher elevation so they carry high flow only. Retaining walls will be used to stabilize road fill in order to keep the proposed culverts within the same footprint as the existing culverts. Due to the flow velocity and volume during heavy rain events, the stream channel below the culverts must be stabilized to prevent erosion of the stream banks and undercutting of the culverts and road. In the existing condition, erosion has created an natural plunge pool below the culverts. In order to stabilize the stream banks, the stream bed and banks will be lined with rip -rap. The bank stabilization has been designed to stabilize the stream channel and banks as they exist now, and no excavation of the stream banks to create formal dissipator is proposed. The rip -rap will be installed by burying the rip -rap such that the top of the rip -rap matches the natural contours of the streams, allowing for the passage of aquatic life and preventing a functional loss of this section of stream. The onsite sewer will connect to the existing City of Raleigh gravity sewer located near the northwest corner of the project. An aerial crossing over Stream 2 will be constructed to avoid stream impacts at this crossing (see Sheet B in the Buffer Impact Maps for the cross-section detail). The project will be constructed using traditional commercial construction equipment and techniques. Proiect History Ross Sullivan with the USACE field verified the wetland delineation for the project on 7/31/19 (SAW-2019-01218). As of the submittal of this PCN, the PJD has not been issued. WR is not requesting issuance of a JD in conjunction with issuance of the NWP 29. The Approved Wetland/Buffer Delineation Exhibit depicting the field verified delineation has been provided as an attachment. NCDWR issued a Riparian Buffer Determination Letter for the project on 6/3/19 (NBRRO#19- 156). A copy of the buffer determination letter has been provided as an attachment. Page 2 of 5 Holly Lane Subdivision - NWP 3 & 13 PCN �: WithersRavenel Our People. Your Success. In December 2019, WithersRavenel submitted an NWP 29 application requesting 118 If of permanent stream impacts, 11 If of temporary stream impacts, 0.021 acres of permanent wetland impacts and 0.026 acres of temporary wetland impacts for the project. All proposed stream and wetland impacts were necessary for the improvements and widening of Holly Lane to meet City of Raleigh requirements. In response to the USACE Incomplete Application letter dated 1/20/2020, WithersRavenel coordinated with the USACE on several occasions, including the meeting on 3/4/2020 with the applicant, USACE and City of Raleigh to discuss the project. The City of Raleigh was initially requiring Holly Lane to be improved to a 20-ft wide two-lane road, with curb and gutter, a 6-ft wide planted strip and 6-ft sidewalks, and graded to accommodate the future widening to 26-ft. The USACE ultimately determined that the proposed impacts for the improvements to Holly Lane to meet City requirements had no immediate connection or purpose and need and could not be authorized under an NWP 29 as a single and complete project. At the meeting, the USACE stated that since there is a culverted crossing for an existing driveway and if the road width could be reduced such that the proposed culverts were the same length as the existing failing culverts, it would be considered maintenance of an existing structure and eligible for a NWP 3. On 5/5/2020, WithersRavenel submitted an email to the USACE and NCDWR formally withdrawing the application submitted in December 2019. Following the withdrawal of the NWP 29 application, the applicant has worked with the City of Raleigh on redesign of the design of the Holly Lane extension and the City has granted a variance to deviate from their standard road design, allowing the road width to be narrowed at the stream crossing, which allows the proposed culverts to be the same length as the existing failing culverts (44 If). The current application request authorization of the stream impact necessary to replace the existing culverts (NWP 3), as well as installation of a rip -rap dissipator to stabilize the stream below the culverts (NWP 13). Proposed Impacts NWP 3 Impacts (Maintenance) The replacement of the existing dual 36-inch RCP culverts, which are undersized and failing, with three box culverts consisting of a 10-ft x 10-ft box culvert to carry base flow, and two 10-ft x 8- ft box culverts which will carry high flow only. The installation of the proposed three box culverts will result in 4 If of temporary stream impacts (Impact 6) during construction. NWP 13 Impacts (Bank Stabilization) Due to the volume and velocity of flow during heavy rain events, the stream channel below the culverts must be stabilized to prevent erosion of the stream and undercutting of the culverts and road. 42 If of stream channel will be stabilized below the culverts (Impact 5). The rip -rap will be installed by burying the rip -rap such that the top of the rip -rap matches the natural contours of the stream, allowing for the passage of aquatic life and preventing a functional loss of this section of stream. Please note that this is not a constructed rip -rap dissipator, but rather bank stabilization that has been designed to stabilize the stream channel and banks as they exist now (see Sheet D of the Wetland & Stream Impact Maps). Page 3 of 5 Holly Lane Subdivision - NWP 3 & 13 PCN :: Withers Rave n e l Our People. Your Success. During installation of the rip -rap stabilization, 6 If of temporary stream impacts (Impact 4) beyond the bank stabilization area may be needed. Riparian Buffer Impacts The sewer crossing necessary to connect the internal sewer to the existing City of Raleigh sewer line will result in 2,189 sf of permanent Zone 1 impacts and 1,361 sf of permanent Zone 2 impacts for construction of the sewer line and perpetual mowing/maintenance of the entire 30' sewer easement. The sewer crossing will a perpendicular crossing impacting less than 40 If of riparian buffer and will have a permanent maintenance corridor greater than 10 If, which is classified as "Allowable" in the Neuse River Riparian Buffer Rules Table of Uses. Please note this will be an aerial sewer crossing and will not result in impacts to Stream 2. The improvements to Holly Lane will result in a total of 13,578 sf of permanent riparian buffer impacts (Zone 1: 8254 sf; Zone 2: 5324 sf). The buffer crossings will be perpendicular, impacting less than 150 If or 1/3 acre of riparian buffer, which is classified as "Allowable" in the Neuse River Riparian Buffer Rules Table of Uses. 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. Impacts have been minimized to only those necessary for infrastructure. There are no proposed wetland or stream impacts for lot fill. The redesign of the improvements to Holly Lane has result in the avoidance of the previously proposed 0.021 acres of permanent wetland impacts and 0.026 acres of temporary wetland impacts. The redesign of the Holly Lane improvements has reduced proposed permanent stream impacts from the previously proposed 118 If to the currently proposed 48 If. Additionally, the redesign shortened the proposed culverts to 44 If, which is the length of the existing culverts, eliminating the previously proposed 67 If of permanent stream impacts with function loss for extension of the culverts to accommodate the wider road. The proposed permanent impacts with no functional loss have been reduced from the previously proposed 51 If to 42 If. Additionally, stream impacts have been minimized through the use of retaining walls to stabilize road fill, as well as the use of an aerial sewer crossing over Stream 2. The rip -rap bank stabilization has been designed for the rip -rap to be installed so that the top of the rip -rap matches the pre -construction elevation of the stream bed. This design allows for the stabilized segment of stream to continue functioning as a natural stream by maintaining natural water depths and allowing for passage of aquatic life. The proposed 10-ft x 10-ft box culvert that will carry base flow will be installed so that bottom of the culvert is at least 12-inches below the stream bed to maintain aquatic life passage during periods of low flow. Additionally, the stream channel is approximately 12-ft wide at the location Page 4 of 5 Holly Lane Subdivision - NWP 3 & 13 PCN :: Withers Rave n e l Our People. Your Success. of the proposed box culvert. Therefore, the installation of the 10'x10' box culvert will not result in widening of the channel and the OHW depth will be maintained. The two additional 10-ft x 8-ft box culverts will be installed at higher elevations so that they only convey high flow. The proposed buffer impacts are necessary to construct a perpendicular road crossing and perpendicular sewer crossing, which are both classified as "Allowable" uses in the Neuse River Riparian Buffer Rules Table of Uses. Mitigation Stream Mitigation The proposed permanent stream impacts consist of 48 If for banks stabilization and will not result in a function loss. Therefore, stream mitigation is not proposed. Buffer Mitigation All proposed buffer impacts are classified as "Allowable" uses in the Neuse River Riparian Buffer Rules Table of Uses, and therefore buffer mitigation is not required. The current request is for 48 If of permanent stream impacts (no functional loss), 10 If of temporary stream impacts and 13,578 sf of permanent riparian buffer impacts (see the attached maps and PCN for details).

Explain the purpose of the proposed project:* The purpose of the proposed project is to construct a residential townhome subdivision with 88 units to meet the need for residential housing in Raleigh. 41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:* The City of Raleigh is requiring Folly Lane to be improved from an existing gravel driveway within a public ROW to a paved two-lane road. The improvements to Folly Lane are necessary both for the construction of the stormwater management pond as well as to meet City of Raleigh requirements for site plan approval. The improvements to the existing Holly Lane requires the replacement of the existing dual 36-inch RCP culverts, which are undersized and failing, with three box culverts consisting of a 10-ft x 10-ft box culvert to carry base flow, and two 10-ft x 8-ft box culverts which will carry high flow only. The significant increase in the size of the culverts is based on the drainage study which determined the size and number of box culverts based on the modeling for conveyance during high flows. In the existing condition, the dual 26-inch culverts are undersized, and result in significant backwater and overtopping of the road during heavy rain events. The head created by the backwaters and overtopping of the road has led to significant erosion and undercutting of the existing culverts which has resulted in the failure and collapse of the culverts. The three box culverts have been designed with the 10-ft x 10-ft box culvert carrying the base flow, with the two 10- ft x 8-ft box culverts being installed at a higher elevation so they carry high flow only. Retaining walls will be used to stabilize road fill in order to keep the proposed culverts within the same footprint as the existing culverts. Due to the flow velocity and volume during heavy rain events, the stream channel below the culverts must be stabilized to prevent erosion of the stream banks and undercutting of the culverts and road. In the existing condition, erosion has created an natural plunge pool belowthe culverts. In order to stabilize the stream banks, the stream bed and banks will be lined with rip -rap. The bank stabilization has been designed to stabilize the stream channel and banks as they exist now, and no excavation of the stream banks to create formal dissipator is proposed. The rip -rap will be installed by burying the rip -rap such that the top of the rip -rap matches the natural contours of the streams, allowing for the passage of aquatic life and preventing a functional loss of this section of stream. The onsite sewer will connect to the existing City of Raleigh gravity sewer located near the northwest corner of the project. An aerial crossing over Stream 2 will be constructed to avoid stream impacts at this crossing (see Sheet B in the Buffer Impact Maps for the cross-section detail). The project will be constructed using traditional commercial construction equipment and techniques. 4j. Please upload project drawings for the proposed project.

Supporting Documentation Buffer Impact Maps.pdf 2.65MB E. Impact Justification and Mitigation 1. Avoidance and Minimization la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the 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. Impacts have been minimized to only those necessary for infrastructure. There are no proposed wetland or stream impacts for lot fill. The redesign of the improvements to Holly Lane has result in the avoidance of the previously proposed 0.021 acres of permanent wetland impacts and 0.026 acres of temporary wetland impacts. The redesign of the Holly Lane improvements has reduced proposed permanent stream impacts from the previously proposed 118 If to the currently proposed 48 If. Additionally, the redesign shortened the proposed culverts to 44 If, which is the length of the existing culverts, eliminating the previously proposed 67 If of permanent stream impacts with function loss for extension of the culverts to accommodate the wider road. The proposed permanent impacts with no functional loss have been reduced from the previously proposed 51 If to 42 If. Additionally, stream impacts have been minimized through the use of retaining walls to stabilize road fill, as well as the use of an aerial sewer crossing over Stream 2. The rip -rap bank stabilization has been designed for the rip -rap to be installed so that the top of the rip -rap matches the pre -construction elevation of the stream bed. This design allows for the stabilized segment of stream to continue functioning as a natural stream by maintaining natural water depths and allowing for passage of aquatic life. The proposed 10-ft x 10-ft box culvert that will carry base flowwill be installed so that bottom of the culvert is at least 12-inches belowthe stream bed to maintain aquatic life passage during periods of lowflow. Additionally, the stream channel is approximately 12-ft wide at the location of the proposed box culvert. Therefore, the installation of the 10'x10' box culvert will not result in widening of the channel and the CHIN depth will be maintained. The two additional 10-ft x 8-ft box culverts will be installed at higher elevations so that they only convey high flow. The proposed buffer impacts are necessary to construct a perpendicular road crossing and perpendicular sewer crossing, which are both classified as "Allowable" uses in the Neuse River Riparian Buffer Rules Table of Uses. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques: Silt fencing will be installed around all disturbed areas and access during construction will be within uplands where possible. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State? r Yes r No 2b. If this project DOES NOT require Compensatory Mitigation, explain why: Permanent stream impacts are less than 150 If will not result in a functional loss and therefore mitigation is not proposed. Additionally, proposed buffer impacts are for "Allowable" uses, and therefore buffer mitigation is not required. LF. Stormwater Management and Diffuse Flow Plan (required by DWR) 1.

City of Raleigh Comments: The storm inter management plan consists of a wet detention SCM which will provide the required nitrogen removal and therefore diffuse flow is not required. Additionally, the pond outfall will discharge through uplands and into the onsite wetlands, and not through the riparian buffers. The stormwater management plan will be reviewed and approved by the City of Raleigh as the certified local government. G. Supplementary Information 1. Environmental Documentation 1a.

Does this project involve (1) blasting, and/or (2) other percussive activities that will be conducted by machines, such as jackhammers, mechanized pile drivers, etc.? r Yes r No 5j. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat? WR reviewed the NC Natural Heritage Program database, located at http://www.ncnhp.org/web/nhp/home, as well as NCNHP GIS data to identify if there were any known occurrences of endangered species on or near the proposed project. The review of the NHP data did not identify any recent occurrences of federally listed threatened or endangered species or critical habitat on the subject property or Within 1.0 miles of the project, see attached NCNHP project review letter. Site reviews did not identify any potential habitat for bald eagle, red -cockaded woodpecker or Michauxis sumac. The project is located in the Neuse River Basin, and therefore is not located within the known range of the Cape Fear Shiner. Additionally, the project is not located within the known range of the Tar River spinyrrussel. The project site is Within the known range of the Carolina madtom, Neuse River waterdog, Atlantic pigtoe, dwarf wedgemussel and yellow lance. The proposed project is located within the lower reach the Lfr to Crabtree Creek. The onsite perennial stream was historically impounded prior to failure of the pond dam in 2016. The onsite perennial stream is now located between two existing impoundments (ponds), which was historically a chain of four impoundments. The presence of these impoundments would prevent the migration of these species to sustain viable populations. Therefore, the perennial stream within the project area was not considered potential habitat for Carolina madtom, Neuse River waterdog, Atlantic pigtoe, dwarf wedgemussel and yellow lance. Therefore, WR concludes that the proposed project will have "No Effect" on federally listed species.

Holly Lane Townhomes; 02170003.00 Dear Troy Beasley. The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. Based on the project area mapped with your request, a query of the NCNHP database indicates that there are no records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence, the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached `Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile radius of the project area, if any, are also included in this report. If a Federally -listed species is found within the project area or is indicated within a one -mile radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here: https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water Management Trust Fund easement, or Federally -listed species are documented near the project area. If you have questions regarding the information provided in this letter or need additional assistance, please contact Rodney A. Butler at rodnev.butlerWncdcr.aov or 919-707-8603.

A taxon "in danger of extinction throughout all or a significant portion of its range." T = threatened. A taxon "likely to become endangered within the foreseeable future throughout all or a significant portion of its range." C = candidate. A taxon under consideration for official listing for which there is sufficient information to support listing. (Formerly "C1" candidate species.) BGPA =Bald and Golden Eagle Protection Act. See below. ARS = At Risk Species. Species that are Petitioned, Candidates or Proposed for Listing under the Endangered Species Act. Consultation under Section 7(a)(2) of the ESA is not required for Candidate or Proposed species; although a Conference, as described under Section 7(a)(4) of the ESA is recommended for actions affecting species proposed for listing. T(S/A) = threatened due to similarity of appearance. A taxon that is threatened due to similarity of appearance with another listed species and is listed for its protection. Taxa listed as T(S/A) are not biologically endangered or threatened and are not subject to Section 7 consultation. See below. EXP = experimental population. A taxon listed as experimental (either essential or nonessential). Experimental, nonessential populations of endangered species (e.g., red wolf) are treated as threatened species on public land, for consultation purposes, and as species proposed for listing on private land. P = proposed. Taxa proposed for official listing as endangered or threatened will be noted as "PE" or "PT", respectively. Bald and Golden Eagle Protection Act (BGPA)_ In the July 9, 2007 Federal Register( 72:37346-37372), the bald eagle was declared recovered, and removed (de- listed) from the Federal List of Threatened and Endangered wildlife. This delisting took effect August 8,2007. After delisting, the Bald and Golden Eagle Protection Act (Eagle Act) (16 U.S.C. 668-668d) becomes the primary law protecting bald eagles. The Eagle Act prohibits take of bald and golden eagles and provides a statutory definition of "take" that includes "disturb". The USFWS has developed National Bald Eagle Management Guidelines to provide guidance to land managers, landowners, and others as to how to avoid disturbing bald eagles. For mor information, visit http://www.fvvs.goy/migratorvbirds/baldeagle.htm Threatened due to similarity of appearance(T(S/A))_ In the November 4, 1997 Federal Register (55822-55825), the northern population of the bog turtle (from New York south to Maryland) was listed as T (threatened), and the southern population (from Virginia south to Georgia) was listed as T(S/A) (threatened due to similarity of appearance). The T(S/A) designation bans the collection and interstate and international commercial trade of bog turtles from the southern population. The T(S/A) designation has no effect on land management activities by private landowners in North Carolina, part of the southern population of the species. In addition to its official status as T(S/A), the U.S. Fish and Wildlife Service considers the southern population of the bog turtle as a Federal species of concern due to habitat loss. Definitions of Record Status: Current - Based on NC Natural Heritage Program information, this taxon is considered to be extant in the county. Historical - Based on NC Natural Heritage Program information, this taxon is considered to be historical in the county, meaning that all recorded occurrences are either extirpated, have not been found in recent surveys, or have not been surveyed recently enough to be confident they are still present. Obscure - the date and/or location of observation is uncertain. Incidental/migrant - the species was observed outside of its normal range or habitat. Probable/potential - the species is considered likely to occur in this county based on the proximity of known records (in adjacent counties), the presence of potentially suitable habitat, or both.
