On behalf of Grubb Palms, LLC, we are requesting authorization from the USACE to use NWP 29 for 148 if of permanent stream impacts for construction of the proposed project. We are also requesting a 401 WQC from NCDWR for the above referenced impacts, as well as a Buffer Authorization for 8,437 sq ft of permanent impacts to Neuse River riparian buffers. The project is ±24 acres in size and is located at 3599 Horton Street, in the southwestern quadrant of the intersection of Lake Boone Trail and Horton Street in Raleigh, Wake County (Latitude: 35.812467 °N; Longitude: - 78.692197 °W). The project is located in the Neuse River basin (HUC 030202o1) and onsite waters drain to House Creek. The Water Quality Classification for House Creek is C;NSW and the Stream Index Number is:27- 33 -13. Proposed Project The proposed project consists of construction of three multi- family apartment buildings, roads, parking and utilities. There are two existing apartment buildings within the project area that are dilapidated and will be demolished as part of the proposed construction of the Greenway Village at Lake Boone Trail project. Project History W &R conducted a wetland delineation for the project site in September 2013. There are no wetlands located within the subject property. There are five streams, including House Creek, within the property. The Preliminary JD Request Packet and supporting information has been submitted with this application to facilitate the Preliminary JD in conjunction with issuance of the NWP 29. All onsite streams are depicted on either the USGS Quad or Wake Co. Soil Survey. Therefore buffer subjectivity is not being contested and a formal Buffer Determination by NCDWR was not requested. Proposed Impacts The proposed impacts consist of 148 if of permanent stream impacts and 8,437 sq ft of permanent impacts to Neuse River riparian buffers for construction of the proposed project. 1410 Commonwealth Drive I Suite 101 ' Wilmington, NC 28403 1 tel: 910.256.9277 j fax: 910.256.2584 www.withersravenel.com 1 License No. C -0832 Of the 148 if of permanent stream impacts proposed, 70 if of permanent stream impacts will occur from construction of a perpendicular road crossing (Impact #1) and replacement of the culverts at an existing crossing of House Creek (Impact #2). The proposed perpendicular road crossing (Impact #1) is necessary in order to access the southern portion of the site. Impact #2 will result in 5 if of permanent stream impacts to House Creek for the removal and replacement of the existing 25 if x 54" culverts at the existing entrance from Horton Street which currently provides access to two existing apartment buildings which will be demolished. The existing culverts will be replaced with 30 if x 54" culverts in order to provide a wider entrance to provide safer entrance /exit to the development, as the current entrance is undersized for the additional traffic that will occur from the increase in units /tenants. Construction of rip -rap dissipater pads below the culverts at the road crossings will result in 78 if of permanent stream impacts (Impact #s sA & 2A). The rip -rap dissipater pads below the culverts are necessary to reduce flow to non - erosive velocities and protect against scouring. The rip -rap dissipaters are a requirement by the NC Division of Land Quality as a sediment and erosion control measure. The rip -rap dissipaters have been designed so that the top of the installed rip -rap matches the pre- construction elevation of the stream bed (see Rip -Rap Apron Detail on Maps A &B). This design allows for the temporary stream impact areas to continue functioning as a natural stream by maintaining natural water depths and allowing for passage of aquatic life. Since the proposed 78 if of permanent stream impacts for the rip -rap dissipater pads (Impact #s sA & 2A) will not result in a "loss" of function, these impacts will not require mitigation. The proposed project will result in 8,437 sq ft of permanent riparian buffer impacts (Zone 1: 4,983 sq ft; Zone 2: 3,454 sq ft) for construction of a road crossing (Impact #6 ), expansion of the existing road crossing at the entrance to Horton Street (Impact #7) and stormwater outfalls (Impact #s 3, 4, & 5). See attached Buffer Impact Exhibits for details. 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. Proposed permanent stream impacts have been minimized to only those impacts necessary to construct a perpendicular road crossing (Impact #1) to access the southern portion of the property and extension of the culverts at an existing road crossing (Impact #2) to provide access to the project from Horton Street. The site plan was designed to utilize the existing crossing of House Creek to access the site to minimize impacts to House Creek. By only proposing to improve the existing crossing (Impact #2), both temporary and permanent impacts to House Creek have been minimized by eliminating the need for removal of the existing crossing and construction of a new crossing to provide access from Horton Street. Also, to minimize impacts to House Creek at Impact #2, a retaining wall will be constructed to stabilize fill and protect the culverts. Impacts to riparian buffers have been minimized to those necessary for the road crossings and required stormwater outfalls. Please note that the proposed BMPs will achieve 30% nitrogen removal and outfall discharges at non - erosive velocities, and therefore, level spreaders are not required. WITHERS ,`." RAVENEL Page 2 of Mitigation Streams Since the proposed permanent stream impacts are less than 150 If, the applicant is not proposing stream mitigation. Buffers All proposed buffer impacts are identified in the Neuse River Riparian Buffer Rules Table of Uses as "Allowable" and therefore, buffer mitigation is not required Stormwater Management Plan & Diffuse Flow The stormwater management plan consists of a combination of a level spreader (BMP #1), bio- retention (BMP #2), constructed wetlands (BMP #3 &5) and a sand filter (BMP #5). BMP #1 is a level spreader, which meets diffuse flow requirements. BMPs # 2, 3, 4 & 5 will provide 3o% nitrogen removal and outfall discharges at non - erosive rates which meets diffuse flow requirements. At this time, preliminary plans have been developed in anticipation of a City of Raleigh site plan submittal The City requires that potential stream and buffer impacts be approved prior to issuing preliminary approvals. The preliminary approval from the City does not entitle the owner to begin construction or begin clearing or grading operations on the subject property. Subsequent to receiving the preliminary approval from the City, W &R will be preparing and submitting full construction drawings for all BMPs shown herein. At that time, we will provide NCDENR with revised supplement forms, details, and plans for each BMP. Should any of the information in this application change during development of the construction drawings, we will apply for a permit revision to ensure that the final permit matches the final drawings approved by the City. The current request is for 148 if of permanent stream impacts and 8,437 sq ft of permanent impacts to Neuse River Riparian Buffers (see the attached maps and PCN for details). Please feel free to call if you have questions or require additional information.
