Project Information Attach a vicinity map clearly showing the location of the property with respect to local landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property boundaries and development plans in relation to surrounding properties. Both the vicinity map and site plan must include a scale and north arrow. The specific footprints of all buildings, impervious surfaces, or other facilities must be included. If possible, the maps and plans should include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion, so long as the property is clearly defined. For administrative and distribution purposes, the USACE requires information to be submitted on sheets no larger than 11 by 17-inch format; however, DWQ may accept paperwork of any size. DWQ prefers full-size construction drawings rather than a sequential sheet version of the full-size plans. If full-size plans are reduced to a small scale such that the final version is illegible, the applicant will be informed that the project has been placed on hold until decipherable maps are provided. 1. Name of project: Blalock's Glen Subdivision 2. T.I.P. Project Number or State Project Number (NCDOT Only): NA 3. Property Identification Number (Tax PIN): 1607-01-7265 4. Location County: Wake Nearest Town: Fuquay-Varina Subdivision name (include phase/lot number): Blalock's Glen (proposed) Directions to site (include road numbers/names, landmarks, etc.): The site is located approximately 1200 feet southwest of Rock Service Station Road (SR 2736) and 3500 feet southeast of Barber Bridge Road's intersection with Rock Service Station Road, east of Angier, Wake County, North Carolina. Figure 1 depicting the location of the property on the US Geological Survey (USGS) Angier, NC 7.5-minute quadran lg e topographic map was provided in the original PCN application submitted for the project. 5. Site coordinates (For linear projects, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) Decimal Degrees (6 digits minimum): 35.5934243 °N 78.6622658 °W 6. Property size (acres) 116 7. Name of nearest receiving body of water: UTs to Middle Creek and Middle Creek 8. River Basin: Neuse (Note -this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: Agricultural fields and a large pond currently occupy the Updated 11/1/2005 Page 2 of 9 site. Land use in the vicinity of the site consists primarily of residential subdivisions with a few agricultural fields. 10. Describe the overall project in detail, including the type of equipment to be used: The project is a residential subdivision in which access roads will be constructed to provide access for individual lots. Heavy equipment typical for road construction will be used to complete the~roject 11. Explain the purpose of the proposed work: The purpose of the project is to develop lots suitable for single-family dwellings. IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USAGE Action ID Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn. Provide photocopies of previously issued permits, certifications or other useful information. Describe previously approved wetland, stream and buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project, list and describe permits issued for prior segments of the same T.I.P. project, along with construction schedules. In April of 2006, Jennifer Burdette of Burdette Land Consulting Inc. conducted a riparian buffer, wetlands, and surface waters evaluation for the proposed project area. On July 7, 2006, Mr. Monte Matthews of the USAGE conducted a field verification the wetland delineation. Maps and data forms in support of the delineation were provided prior to the verification meeting. Duringour site meeting BLC consulted with Mr. Matthews regarding a proposed road stub to the western property line. This road stub would cross a jurisdictional stream channel prior to its termination at the property line to satisfy the requirements for a proposed collector road according to Wake County Planning's Throu~hfare Plan. On July 24, 2006 Ms. Jean B. Manuele of the USAGE sent the letter to the property owner stating that similar permit requests have not been reviewed favorably and historically have been withdrawn by applicants, modified to eliminate the jurisdictional impacts, or denied. A copy of this letter was provided in the original PCN application. However, Wake County maintains that the road- stub is required because the letter did not represent an actual denial. On March 8, 2007, the applicant received a letter from NCDWQ requirin dg evelopment planned for the other side of the stream channel or a potential connecting road. The road stub serves only for a potential future road connection; therefore, it has been eliminated from the project accordingly. On June 6, 2006, BLC met Ms. Periann Russell on the site to conduct buffer determinations for those surface waters subject to the Neuse River Basin riparian buffer rules (NBRRO 06-150). Ms. Russell's written documentation of the site meeting was provided with the original PCN application. V. Future Project Plans Are any future permit requests anticipated for this project? If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application. Updated 11/1/2005 Page 3 of 9 Future permit requests are not anticipated for this project. VI. Proposed Impacts to Waters of the United States/Waters of the State It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to wetlands, open water, and stream channels associated with the project. Each impact must be listed separately in the tables below (e.g., culvert installation should be listed separately from riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts, permanent and temporary, tnust be listed, and must be labeled and clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) should be shown on a delineation map, whether or not impacts are proposed to these systems. Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: The proposed impacts consist of one road crossing of a buffered stream channel and minor jurisdictional and isolated wetlands impacts associated with one of the road crossings and well construction. A revised Figure 3 with Insets A and B are attached to show the details of these impacts. 2. Individually list wetland impacts. Types of impacts include, but are not limited to mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams, separately list impacts due to both structure and flooding. Wetland Impact Type of Wetland Located within Distance to Area of Site Number Type of Impact (e.g., forested, marsh, 100-year Floodplain Nearest Stream Impact (acres) (indicate on map) herbaceous, bog, etc.) ( es/no) (linear feet) 1 (inset A) fill forested no 0 0.001 2 (inset B) fill herbaceous no 65 0.007 Total Wetland Impact (acres) 3. List the total acreage (estimated) of all existing wetlands on the property: 24 4. Individually list all intermittent and perennial stream impacts. Be sure to identify temporary impacts. Stream impacts include, but are not limited to placement of fill or culverts, dam construction, flooding, relocation, stabilization activities (e.g., cement walls, rip-rap, crib walls, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included. To calculate acreage, multiply length X width, then divide by 43,560. Stream Impact Number (indicate on ma) Stream Name Type of Impact Perennial or Intermittent? Average Stream Width Before Im act Impact Length (linear feet) Area of Impact (acres) 1 UT to Middle Ck culvert/ri ra P 8 109 0.02 Total Stream Impact (by length and acreage) 109 0.02 Updated 11/1/2005 Page 4 of 9 5. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.). Open water impacts include, but are not limited to fill excavation rlrerluin~_ fln~rlinh_ draina~e_ bulkheads_ etc_ Open Water Impact Name of Waterbody Type of Waterbody Area of Site Number (if applicable) Type of Impact (lake, pond, estuary, sound, bay, Impact (indicate on ma) ocean, etc.) (acres) NA Total Open Water Impact (acres) 6. List the cumulative impact to all Waters of the U.S. resulting from the project: Stream Impact (acres): 0.02 Wetland Impact (acres): 0.008 Open Water Impact (acres): NA Total Impact to Waters of the U.S. (acres) 0.028 Total Stream Impact (linear feet): 109 7. Isolated Waters Do any isolated waters exist on the property? ®Yes ^ No Describe all impacts to isolated waters, and include the type of water (wetland or stream) and the size of the proposed impact (acres or linear feet). Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. The proposed well construction would impact 0.007 acre of isolated wetland (see inset B). NCDWQ's letter requesting additional information mentioned previously also requested relocation of the wells on lot numbers 35 and 36 to avoid impacts to isolated wetland. These lots are valued at approximately $60,000 each for a total economic loss of $120,000 to the applicant to avoid impacts to an isolated wetland that is not high quality (linear ditches or drainages) and small enough to be below the threshold for written notification of isolated wetland impacts. Therefore, the applicant contends that relocating these wells to lot numbers 35 and 36 would be impractical. 8. Pond Creation If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ^ uplands ^ stream ^ wetlands Describe the method of construction (e.g., dam embankment, excavation, installation of draw-down valve or spillway, etc.): NA Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): NA Current land use in the vicinity of the pond: NA Size of watershed draining to pond: NA Expected pond surface area: NA Updated 11/1/2005 Page 5 of 9 VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. The applicant retained Burdette Land Consultin>?, Inc. to conduct a preliminary investigation of surface waters and wetlands on the subject property during the preliminary design stages of the project to avoid impacts to the maximum extent practicable. Stream impact 1 is necessary to access high rg ound separated by a buffered stream channel and pond. VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strmgide.html. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a Updated 11/1/2005 Page 6 of 9 description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. The applicant avoided impacts to streams and wetlands where possible and minimized stream channel impacts that were unavoidable to the maximum extent practicable. A 50- foot-wide riparian buffer will be maintained around stream channels present within the development in accordance with Neuse River Basin Riparian Buffer Rules and will serve as a permanent, vegetative buffer to the stream channels and pond on the site. BLC believes stream channel and wetland mitigation should not be required. The impact to a stream channel (109 LF) is less than 1501inear feet. Impacts to,iurisdictional wetlands (0.007 acre) is less than the U5ACE's 0.10-acre threshold for wetland mitigation and impacts to jurisdictional and isolated wetlands (0.015 acre) is less than the NCDWQ's 1-acre threshold for wetland mitigation. 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability, and written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form. For additional information regarding the application process for the NCEEP, check the NCEEP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please check the appropriate box on page five and provide the following information: Amount of stream mitigation requested (linear feet): NA Amount of buffer mitigation requested (square feet): NA Amount of Riparian wetland mitigation requested (acres): NA Amount of Non-riparian wetland mitigation requested (acres): NA Amount of Coastal wetland mitigation requested (acres): NA IX. Environmental Documentation (required by DWQ) Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land? Yes ^ No 2. If yes, does the project require preparation of an environmental document pursuant to the requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)? Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA coordinator at (919) 733-5083 to review current thresholds for environmental documentation. Yes ^ No ^ If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Yes ^ No ^ Updated 11/1/2005 Page 7 of 9 X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. 1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify )? Yes ® No ^ 2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Zone* Impact (s uare feet) Multiplier Required Miti ation 1 7,740 3 (2 for Catawba) NA 2 8,885 1.5 NA Total 10,625 NA * Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an additional 20 feet from the edge of Zone 1. 3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Riparian Buffer Restoration /Enhancement, or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0244, or .0260. Because the proposed road crossing is peroendicular and does not exceed 150 linear feet of stream channel or one-third acre of r~arian buffer impact, BLC does not believe riparian buffer mitigation should be required for the project. XI. Stormwater (required by DWQ) Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss Stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. The site does not currently contain impervious acreage. Upon completion of the proiect. Keith Roberts. PE, does not anticipate that the percent impervious surface for the project will exceed 15%, which is the Wake County maximum for the Updated 11/1/2005 Page 8 of 9 Maintenance of riparian buffers is anticipated to protect surface waters and wetlands downstream from the property. It is important to note that the proposed subdivision does not include curb and gutter. As requested in the aforementioned NCDWO letter requesting additional information Keith Roberts, PE designed four grass swales upon consultation with Ms. Annette Lucas of NCDWQ re~ardin~ compliance with the diffuse flow provision of the riparian buffer rules Worksheets, supporting calculations, and an operations and maintenance agreement for the proposed gassed swales are attached. XII. Sewage Disposal (required by DWQ) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. Wastewater generated from the proposed project will be disposed of through individual septic systems approved by Wake County. XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules? Yes ^ No Is this an after-the-fact permit application? Yes ^ No XIV. Cumulative Impacts (required by DWQ) Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality? Yes ^ No If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with the most recent North Carolina Division of Water Quality policy posted on our website at http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: The proposed infrastructure serves only the proposed residential subdivision• therefore it is not anticipated to result in additional development. XV. Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control). NA Agent's mature is valid only if an authorization letter from the applicant is provided.)
