Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The Muddy Creek and Eastland Branch watersheds were once rural watersheds dominated by forested, agricultural, and pasturelands between 1938 and 1966. Increases in population within the Charlotte metropolitan area resulted in the expansion and construction of such major thoroughfares as US 74 and Albemarle Road that facilitated the migration of population and urban development east of Charlotte toward the Muddy Creek and Eastland Branch watersheds. Between 1966 and 1986 an increase in high density residential land uses occurred and corresponded with the encroachment of the Charlotte city limits upon the Muddy Creek and Eastland Branch watersheds following 975. Since 1986, residential landuses, consisting of 0.25- to 0.50-acre lots and 0.25-acre multifamily complexes, have continued to expand throughout the watersheds at the expense of the remaining forested, agricultural, and pasture lands. Muddy Creek's mainstem is 4,467 linear feet (LF). It is a perennial, channelized stream with a flow regime dominated by urban storm water runoff and is showing evidence of stream bank erosion, poor bedform diversity and channel incision. Eastland Branch's mainstem is 2,906 LF. It too is a perennial, channelized stream with a flow regime dominated by urban storm water runoff Stream bank erosion, poor bedform diversity and channel incision are evident on Eastland Branch. There Page 7 of 16 are twelve wetlands that lie within the study corridor of this project Site Map). Wetland 1 is is an old farm pond that has had a breach in the wall of the dam and consists of both herbaceous and woody wetland species. Wetland 2 is located in a powerline easement and consists of both herbaceous and woody wetland species. Wetland 3 and wetland 5 are toe of slope wetlands that consist of mostly woody wetland species. Please note that Wetland 4 was identified in the backyard of an adjacent landowner and outside of the proposed project area, therefore it is not discussed. Wetland 6 is located within the floodplain of Muddy Creek at the toe of a slope and consists of a mix of woody and herbaceous wetland species. Wetland 7 is located at the toe of a slope within the floodplain corridor and consists of mostly woody wetland species. Wetland 8 is located in a remnant farm pond and consists of a mix of woody and herbaceous wetland species. Wetland 9 is a forested toe of slope wetland Wetland 10 is located in a powerline easement and consists of mostly herbaceous wetland species. Wetland 11 and 12 are foresed wetlands with some herbaceous wetland species located at the toe of slope between a parking lot and Eastland Branch. Site 4, also referred to as Wetland 8, is a small, breached pond/wetland system (approximately 0.21 acres) that receives high pollutant loads from its drainage area and discharges into Cedarwood Tributary that enters Muddy Creek just above Reddman Road. Site 10 is an existing, degraded amenity pond (0.52 acres). It is situated on Muddy Creek in the left floodplain just downstream of Reddman Road. This pond has been drained or can no longer hold water. Site 9A is an existing detention pond that receives drainage containing high pollutant loads and discharges east toward the mainstem of Eastland Branch. Site 9B receives stormwater runoff from an adjacent office park. See the Site Plan figure for locations of existing project features and the Photo lou for documentation of existing conditions. 10. Describe the overall project in detail, including the type of equipment to be used: This project proposes to restore, enhance, and/or stabilize 7,533 linear feet (LF) of channelized and incized stream within the Muddy Creek Watershed. In addition, the project will enhance and preserve 5.7 acres of wetland and implement four water quality Best Management Practices BMPs) within the drainage area. At the beginning of the project area on Eastland Branch, Enhancement I will be implemented from Station 10+00 to 15+00 to stabilize stream banks and connect the channel to the existing culvert. To the west of this reach a constructed wetland 9A) will be implemented to treat run-off from a highly impervious drainage area of 8.1 acres. At station 15+00, Priority I and II Restoration will be implemented throughout the channel to station 32+50. Priority II Restoration will be used to tie the Priority I sections for the channel to the Enhancement areas. From station 32+50 to 37+00, Enhancement I will be implemented. To the east of this reach a constructed wetland (9B) will be implemented and discharge into the channel at station 35+75. This BMP will treat 13.3 acres of run-off from an adjacent office park. From station 37+00 to Eastland Branch's confluence with Campbell Creek, work will consist of Priority I and II Restoration. Priority 11 Restoration will be used to tie the Priority 1 Restoration into the upstream section of the channel and to Campbell Creek. The upstream section of Muddy Creek flows through an existing wetland from station 10+00 to 23+25. Enhancement I will be implemented throughout station 10+00 to 24+81. Priority I and II Restoration will be implemented throughout Reach 2 from station 24+81 to 37+75. Priority II will be implemented to tie the Priority I sections of the reach back into the existing channel. Enhancement II will be implemented from station 37+75 to 50+00. To the east of the channel in this reach is an existing pond. This pond is to be Page 8 of 16 retrofitted to treat 13.9 acres of runoff from an adjacent residential neighborhood. From station 50+00 to Muddy Creek's confluence with Campbell Creek, work will consist of Priority I and II Restoration. Priority II Restoration will be used to tie the Priority 1 Restoration into the upstream section of the channel and to Campbell Creek. At Site 4 an existing wetland will be retrofitted to also treat stormwater from the surrounding drainage area. Bank stabilization will be implemented within Cedarwood Tributarupstream of its confluence with Muddy Creek. Wetland 1 and Wetland 7 enhancement work will include invasive species removal, planting of native species, grading to improve hydrologic function and the incorporation of wetland microtopography. Constructed wetlands will be implemented at Sites 9A and 9B and an existing amenity pond at Site 10 will be retrofitted into a retention pond for stormwater treatment from surrounding drainage areas. All channel work will be conducted off-line where feasible, and pump around systems will be employ where the proposed channel intercepts the existing channel. Construction equipment to be used onsite will include excavators, bull dozers, and track trucks. No offsite borrow or spoil sites will be needed. 11. Explain the purpose of the proposed work: The purpose of this project is to create geomorphically stable channel conditions for both Muddy Creek and Eastland Branch, improve and restore hydrologic connectivity between the creeks and their floodplains, improve water quality by reducing total suspended soils and nutrient loading, improve aquatic and terrestrial habitat within the project corridor, and generate mitigation credits for the City of Charlotte's Umbrella Mitigation Bank. In addition, the proposed design will increase the total existing channel length of Muddy Creek and Eastland Branch from 7,373 LF to 8,163 LF. 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 USACE 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. A verification of jurisdictional determination QD) was submitted to the US ACOE on May 29, 2008. As of this time, verification for the 7D has not been received. This request for a NW 27 and 43 are in reference to the information previously submitted for the 7D. A floodplain development permit has been applied for and submitted to Mecklenburg County. The stream restoration and enhancement components of this project are currently being considered for mitigation credit by the MBRT. Upon acceptance, the credits will be applied to the City of Charlotte's Mitigation Bank for future use on projects as allowed by the City's MBI. 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. Page 9 of 16 It is anticipated that the addition of a culvert or a low water crossing will be included in this project and we are requesting to submit this section of the project as an addendum for 401/404 certification. This part of the project is currently in the design phase and will be located within the Muddy Creek reach of the project at station 44+50. This structure will be used as a greenway crossing and has been considered as an impact within the stream related impacts of Reach 3. 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, must 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. I. Provide a written description of the proposed impacts: Impacts will include the restoration, enhancement, and/or stabilization of 7,533 LF of existing channelized and incised stream within the Muddy Creek Watershed, 4,467 LF on Muddy Creek, 160 LF on Cedarwood Tributary, and 2,906 LF on Eastland Branch, respectively. Impacts to Waters of the State will include the Priority I and II Restoration and Enhancement along Muddy Creek and Priority I and II Restoration and Enhancement along Eastland Branch. Wetland enhancement is proposed for Wetlands I and 7 will result in minor impacts from clearing and grading. Areas of Wetlands I and 7 that abut or lie adjacent to channel reaches receiving Priority I Restoration may experience clearing= grading and excavation impacts when reconnecting each channel's streambank with its floodplain and/or creating the new stream alignment. A constructed wetland is to be implemented at Site 4, as well as, minor bank stabilization is proposed for 160 LF of Cedarwood Tributary at its confluence with Muddy Creek. The construction of Site 4's BMP will create excavation and grading impacts to Wetland 8. Site 10 will impacts 0.65 acres of the existing amenity pond from clearing= grading, and excavation. See the Project planset, the Proposed Design Map, and Site Map for additional details. 2. Individually list wetland impacts.

Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. N/A 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.): Site 4: Excavation, planting, stabilization, and weir improvements. Site 9A and 913: Installation of concrete riser, wetland plantings, a water quality orifice, a channel protection orifice, an emergency spillway, and a forebay. Site 10: Increase drainage area, planting, and reconstruct embankment, outlet pipe, and spillway, installation of a forebay and an aquatic shelf, and invasive species removal.

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 proposed impacts are required to restore stream functions, reconnect the stream channels to their floodplains, improve water quality, relieve high flow shear stresses, and stabilize eroding stream banks. The project will ultimately result in a positive impact to the stream corridor by enhancing stream function and aquatic habitat, improving water quality, increasing the water table elevation in adjacent wetlands, and increase the overall stream length from 7,533 LF to 8,163 LF. Silt fence and high hazard fencing will be installed around wetland areas that lie within active work zones to keep equipment and activity out of the wetland minimizing any additional wetland impacts. In Wetland 1 where the limits of disturbance lies within the limits of the wetland, silt fence and high hazard fence will not be installed within the wetland boundaries. No work will be performed outside the limits of disturbance in Wetland 1, therefore, minimizing additional impacts. In addition, wetland impacts are positive in nature and will exhibit a rise in base now elevation due Priority I Restoration on reaches adjacent to or abutting. Construction practices will follow guidelines from the June 2006 Edition of the NC Erosion and Sediment Control Planning and Design Manual, the Charlotte Land Development Standards Manual, and the City of Charlotte Soil Erosion and Sediment Control Ordinance, or the more restrictive of any standards that conflict. 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. Page 13 of 16 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 .//h2o.enr.state.nc.us/r c 's/st. _ .1_ ml. 1. Provide a brief description of the proposed mitigation plan.

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 ? 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 Multiplier Required 1 3 (2 for Catawba) 2 1.5 Total * 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. N/A 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 project involves work in the stream corridor and it adiacent floodblain. No impervious area will be added to this broiect: therefore. this section is not applicable. XIL Sewage Disposal (required by DWQ) Page 15 of 16 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. NA 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 D Q) Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality`? Yes [] No El 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:lih2o enr.state.nc us pe.wettands. If no, please provide a short narrative description. This is a stream restoration ro ectlhat includes a conservation easement over the entire project area. The easement is to be held-by-the City of Charlotte and will restrict an future development of the 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-dawn schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control). An in-office review of information provided b US Fish and Wildlife Service USFWS NC National Heritage Program NCNH and associated reference material was undertaken prior to conducting fieldwork. A pedestrian survey of the project area was conducted on March 22 W 23, 2004 to identif the general habitats existing within and near the area. No federally listed threatened endangered, candidate orspecies of concern have been recorded within 1.0 mile of the project area based upon the NHP database checked on Aril 19, 2004. No federal or state protected species were observed in or, adjacent to the roject area during the field survey. Critical habitat for the listed species, as defined b the USFWS is not desi nated in the ro osed ro'ect area. The NC Sate Historic Preservation Office SHPfl conducted a review of the Mudd Cheek Watershed Restoration Project and surmised that no historic resource would be affected b the project. A co of the SHPO letter is included in the PCN package.
