Division of Water Quality Asheville Regulatory Field Office 401 Oversight and Express Permits Unit Attn: Amanda Jones Attn: Cyndi Karoly 151 Patton Avenue, Room 208 2321 Crabtree Boulevard, Suite 250 Asheville, NC 28801-5006 Raleigh, NC 27604-2260 v Dear Mrs. Jones ar~d Mrs. Karoly: We request the use of Nationwide Permit 39 for the proposed "Club at Northlake" development in Charlotte, NC. The applicant is Jim Homan with Charter Properties. A signed agent authorization accompanies the enclosed preconstruction authorization. As proposed, the proposed project will involve the construction of multifamily apartments on t25 acres of land. The subject property is located on Reames Road west of I-77. The site is a mixture of open and forested land with surface waters flowing to Long Creek (C- 303d). S&EC has delineated wetlands, one isolated wetland, unnamed tributaries to Long Creek and Long Creek on the property. On May 22, 2006 our delineation was approved by the USACE (Action ID #200630729). The approximate property boundaries are shown on the attached USGS Topo Quad vicinity map. A 100' SWIM buffer has been established along Long Creek. The applicant proposes to impact 3401inear feet (.02 acres) of intermittent stream channel for storm water management facilities. The USACE and NC DWQ determined the section of stream proposed for impact intermittent and non-mitigable. A small isolated wetland (835sf) will be impacted due to grading. No other impacts to jurisdictional features are proposed. Approximately 0.39 acres of wetland and 2701f of stream will be avoided. No impacts are proposed to perennial streams, including Long Creek. Due to the classification of Long Creek (C/303d) project engineers have designed a wet pond followed by forested filter strip and level spreader to meet NC DWQ BMP specifications. Based on the proposed impacts and plans the client asserts adverse effects of the project are minimal without mitigation. Initial site plans that involved storm water facilities outside the stream could not be facilitated due to cost and logistics (see attached letter). DWQ level spreader and wet detention basin worksheets are included with this submittal.

Size of watershed draining to pond: 20.Sac Expected pond surface area: 0.4 acres VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It maybe useful to provide inforrnation 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. Due to topographic contstraints of the site the location of the proposed stormwater management facilities are planned to impact jurisdictional waters. The stream to be impacted was determined intermittent and unimportant by the USACE and intermittent and not significant by DWQ The applicant and their engineers looked at adding multiple ponds in uplands and constructing len by retaining walls to avoid the stream. However, the economics and logistics of meeting DWQ BMP's was prohibitive (see attached letter from applicant). 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, Page 9 of 12 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 USAGE 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. 1. 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 description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. Based on the amount proposed impact and quality of the stream to be impacted the contends no compensato mitigation reauired Impacts due to stormwater management facilities as required by City of Charlotte and NC DWO. No jurisdictional wetland impacts proposed (0.39 acres avoidance) and 2701f of stream (a portion determined perennial by DWQ will be avoided. Stream impacts proposed at the upper end of the stream A 100' SWIM buffer is established along Long Creek and will be adhered to Buildings roads etc were designed to occupy upland (non wetlandl areas of property Additional SWIM buffer area has been established on the site (hatched area) in the floodplain of Lon Cg_ reek 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.

Mr. Wendel] Overby Soils and Environmental Consultants 236 LePhillip Court, Suite C Concord, NC 28025 Re: The Club at Northlake: A Proposed Apartment Community Reamer Road, Charlotte, NC NCDWQ Justification Letter To whom this may concern: Charter Properties, Inc. is the owner and developer of the proposed "The Club at NorthLake". apartment community located adjacent to Long Creek off of Reames Road in Charlotte, NC. Your firm, S & EC, has preformed the wetland delineation, .previously approved .by .the USACE, for the .entire yite., Our current planning and design involves roughly one half of our. total ,acreage with the remainder to tie potentially developed in some fashion, or even sold, at some undetermined future date. We are planning for this phase of development, and any. potential future phase, to be designed so they individually meet all established and required development standards. As part of the development •and planning process we are working under City of Charlotte and NC DWQ specifications to create an acceptable storm water management system for our proposed apartment community. To that end we have evaluated and priced different pond designs to accommodate the water quality and detention requirements. Our first approach was to locate ponds on the steep slopes adjacent the ,ong Creek flood line Due to the extreme topography (63 feet of vertical fall across the site) we found the ponds would require expensive cast in place concrete retaining walls, concrete dams essentially, on the down slope side of the proposed ponds. In addition to the constraints of the severe terrain, there is a required I S% tree save area which presents more area limitations. Consequently, the required storm water management pond needs to be located in an area that will minimize the impacts to existing trees and an overall design that incorporates a forested filter strip and level spreader pis per NC DWQ specifications. A.preliminary estimated cost of .almost X850,000 for.the cast in place concrete. retaining walls was not. economically` acceptable, plus there; were additional costs related to the excavation into the side of.the steep existing slopes and constructing.addifional, retai-Wing walls to support the exposed embankment. The total pond constrl~ction .costs of this scheme were simply not feasible and could not he supported. by the proposed apartment project.
