Please note that the permit fee of $570.00 will be sent directly from the City of Charlotte. As part of this submittal, we have included the following supporting data on the project:  PCN Form,  Agency Correspondence (USFWS, NCWRC, SHPO, OSA, NCNHP, and NC State Environmental Clearinghouse),  Map Figures (Vicinity Map, USGS Topographic Map, Soils Map, Jurisdictional Impact Summary Maps, Project Area Map, Alternative Alignment Areas Map, and Floodzone Map),  (2) full size and (3) half size copies of the Site Plans,  Geotechnical Reports of the subsurface soils at each bottomless culvert crossing,  Agent Authorization Form The Project is proposing a new connector roadway, which will begin at the intersection of IBM Drive and the Martin Middle School Driveway in Charlotte, NC, cross over I-85, and connect to the main thoroughfare being constructed as part of the Crescent Resources’ Belgate Development and will intersect with IKEA Boulevard and University Pointe Boulevard upon completion. An alternative access road for Charlotte-Mecklenburg Schools has also been proposed to ease traffic congestion and improve safety during school pick-up and drop-off times. The access road will begin approximately 600 feet southeast of Neal Road on the campus of Zebulon Vance High School, cross over Doby Creek, and connect to an existing traffic circle and auxiliary parking lot located on the campus of James Martin Middle School. University Pointe Blvd. Extension Project PCN Additional Information 1 | P a g e SECTION B. Project Information and Prior Project History 3d. Explain the purpose of the project. The purpose of the proposed project is to provide additional east-west connectivity in the Charlotte Northeast Corridor, between IBM Drive and North Tryon St. and provide an alternative entry/exit point to James Martin Middle School. This will to create multi-modal travel alternatives, specifically for pedestrians and bicyclists, will aid in reducing emergency response times, and will improve access to the proposed Blue Line Extension (BLE). 3e. Describe the overall project in detail, including the type of equipment to be used: This project, identified as University Pointe Boulevard (UPB), formerly Shopping Center Drive, by the City of Charlotte (City), proposes to extend UPB over I-85 from the IKEA Boulevard (approximately 0.4 miles west of US 29 to IBM Drive), in Charlotte, Mecklenburg County, a length of approximately 0.5 miles. This project includes a grade separated crossing of I-85. Because the extension of UPB to IBM Drive will overlay the existing access road to James Martin Middle School an alternative access road is pr oposed to serve the Middle School. The access road will begin approximately 600 feet southeast of Neal Road on the campus of Zebulon Vance High School, cross over Doby Creek, connect to the James Martin Middle School driveway between the school and the athletic fields and tie into the existing traffic circle on the school campus. See the Project Area Map for a depiction of the proposed alignment for both roadways. Typical grading equipment will be used for the construction of the road (i.e. graders, curb machines, rollers, back hoes, pavers, dump truck, crane for the placement of the culvert, pick-up trucks). The culvert and wing walls are precast. University Pointe Blvd. Extension Project PCN Additional Information 2 | P a g e SECTION C. PROPOSED IMPACTS INVENTORY 3.

University Pointe Blvd. Extension Project PCN Additional Information 3 | P a g e D. Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures take to avoid or minimize the proposed impacts in designing the project. The following measures were used to avoid and/or minimize the proposed impacts during the project’s design:  Implemented bottomless culverts at both crossings on Doby Creek.  Aligned all outfalls to discharge in the floodplain to increase infiltration, reduce discharge quantities and velocities, and improve water quality.  Removed the grass strip between the road and the sidewalk at the creek crossing of UT1 to reduce the length of the pipe.  The pipe on UT1 will be buried to allow for aquatic passage.  Did not change the outfall on UT1A so that this project would not further impact the channel.  Reduced the lengths of the rip rap outfalls on UT1 and UT5.  Removed drainage discharges from UPB on south side of Doby creek where slopes were steep and floodplain area was limited.  Designed the road widening and outfalls along UPB so that there would be no impacts to the UT4 or the wetland.  Used an alternative alignment for the SAR to elim inate impacts to wetlands along Doby Creek behind James Martin Middle and the existing riparian buffer. See Alternative Alignment Areas Map for a depiction. 1b. Specifically describe measures take to avoid or minimize the proposed impacts through construction techniques. The following construction measures will be implemented to minimize and/or avoid proposed impacts:  A combination of clean water diversions, temporary diversions, and sediment basins will be used throughout the project boundaries and during pipe and culvert installations.  Installation of each bottomless culvert will be conducted so that there will only be minimal and temporary impacts to Doby Creek. Culvert footings will be located outside the channel at a level below the stream bed. See cross sections depicted in the plan set.  Construction practices will follow guidelines from the Charlotte Land Development Standards Manual and the NC Erosion and Sediment Control Planning and Design Manual. NC Erosion and Sediment controls will be implemented and will follow requirements outlined in the NCDENR NPDES NCG010000 permit.  Stream bank grading will be minimal and only what is needed to stabilize the stream banks after bottom culverts and stormwater structures are installed.  High hazard silt fence will be installed along work areas adjacent to S.W.I.M buffers and wetlands to provide protection from sedimentation, but to also serve as a visual marker to their location.  No onsite wetlands will be disturbed. F. Supplementary Information 8. Flood Zone Designation (Corps Requirement) 8b. If yes, explain how project meets FEMA requirements: Data for potential floodplain effects were downloaded from the North Carolina Floodplain Mapping website on March 27, 2011. The effective dates of the downloaded Digital Flood Insurance Rate Maps (DFIRM) for Mecklenburg County were March 2, 2009. The Doby Creek floodplain has been studied by University Pointe Blvd. Extension Project PCN Additional Information 4 | P a g e Detailed Methods, and the Effective HEC-RAS hydraulic model was obtained from the Mecklenburg County Flood Mitigation Program. Preliminary hydraulic analysis was conducted for each crossing and resulted in an increase in the 100-year Base Flood Elevation (BFE) upstream of the bridge on UPB of about 0.6 feet and upstream of the culvert on the SAR by about 2 feet. Since the proposed project will result in modifications to the Floodway, as well as increases to the BFE, a Conditional Letter of Map Revision (CLOMR) will need to be obtained from the Mecklenburg County Floodplain Mitigation Program prior to construction. A single CLOMR application will need to be prepared to cover both crossings. The City is coordinating with the NC Floodplain Mapping Program (FMP), the delegated state agency for administering FEMA’s National Flood Insurance Program, to develop the approval of a CLOMR and subsequent final Letter of Map Revision (LOMR).

Hinson Water Quality Program Specialist cc: File April 20, 2010 Ms. Christine Miller Michael Baker Engineering, Inc. 1447 South Tryon Street, Suite 200 Charlotte, North Carolina 28203 Dear Ms. Miller: Subject: Proposed Shopping Center Drive Alignment Project, Charlotte, Mecklenburg County, North Carolina In your letter of March 23, 2010, you requested our comments about the subject project. The following comments are provided in accordance with the provisions of the National Environmental Policy Act (42 U.S.C.§ 4321 et seq.) (NEPA); the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e); and section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act). According to your letter, the Shopping Center Drive Alignment Project involves the design and construction of a new connector roadway that will begin at the intersection of IBM Drive and the Martin Middle School Driveway, cross over 1-85, and end about 300 feet west of the future intersection of Shopping Center Drive and IKEA Boulevard. This process will involve conducting preliminary site surveys, alternatives analysis, design, natural resource permitting, and construction. General Comments. We have several concerns with the proposed project. Our principle concern with this project is the potential impacts to Doby Creek associated with the proposed road crossing and the potential for secondary development to result in additional impacts to the creek. Federal Endangered and Threatened Species. Your letter correctly points out that there are five federally protected species in Mecklenburg County: Schweinitz's sunflower (Helianthus schweinitzii), bald eagle (Haliaeetus leucocephalus) (currently protected through the Bald and Golden Eagle Protection Act), Smooth coneflower (Echinacea laevigata), Michaux's sumac (Rhus michauxii), and the Carolina heelsplitter (Lasmigona decorata). Biologists with your 2 company conducted a field survey for Schweinitz's sunflower on September 9, 2009. No individuals of the sunflower were observed throughout or adjacent to the project area. Though no individuals were found within the project area, because suitable habitat is present, you have concluded that the subject project "may affect, but is not likely to adversely affect" Schweinitz's sunflower. Suitable habitat does not exist on the site for the bald eagle and the project will have "no effect" on this species. Biologists with you company will be conducting field surveys for Smooth coneflower and Michaux's sumac during the blooming season this summer (both species bloom from June to mid-July). During this field assessment, biologists will also examine the bank condition and substrate of Doby Creek, which bisects the project area, to determine if suitable habitat exists for the Carolina heelsplitter. We concur with your determination for Schweinitz’s sunflower and agree the project will not affect the bald eagle. We will await this summer’s status surveys/site assessments for the other three species before determining whether the requirements under section 7 of the Act are fulfilled. Stream Impacts. One of the most important and effective measures that can be taken to protect stream health is the preservation of riparian buffers. Wide, contiguous riparian buffers have greater and more flexible potential than other options to maintain biological integrity 1 and can ameliorate many ecological issues related to land use and environmental quality.2 Riparian buffers accomplish the following: 1. catch and filter runoff, thereby preventing nonpoint-source pollutants from reaching streams; 2. enhance the in-stream processing of both point- and nonpoint-source pollutants; 3. act as “sponges” by absorbing runoff (which reduces the severity of floods) and by allowing runoff to infiltrate and recharge groundwater levels (which maintains stream flows during dry periods); 4. catch and help prevent excess woody debris from entering the stream and creating logjams; 5. stabilize stream banks and maintain natural channel morphology; 6. provide coarse woody debris for habitat structure and most of the dissolved organic carbon and other nutrients necessary for the aquatic food web; and 7. maintain air and water temperatures around the stream. For most projects, we recommend the maintenance or establishment of minimum 100-foot native forested buffers along each side of perennial streams and 50-foot native forested buffers along each side of intermittent streams and wetlands.3 ,4 We additionally encourage the 1R.

Appl. 3:209-212. 3For projects potentially affecting waterways that contain federally listed species, the above-recommended buffer 3 implementation of buffers on ephemeral streams due to the important functions they provide as headwater streams.5 , 6 Buffers should be measured horizontally from the edge of the stream bank,7 which may result in wider buffers at higher gradients. Stream Crossings. We strongly recommend the use of bridges for all stream crossings. We recommend a bridge that spans the entire floodplain because it is important for streams to have access/connectivity to the floodplain. Bridges that span the stream and floodplain are the best option because they minimize impacts to aquatic resources, allow for the movement of aquatic organisms, and eliminate the need to place fill in streams and floodplains. Bridges should be designed and constructed so that no piers or bents are placed in the stream, and approaches and abutments should not constrict the stream channel. Bridge should also be designed to allow for safe terrestrial wildlife passage. To provide for terrestrial wildlife passage, the new bridge designs should span beyond the waterways so that unsubmerged land is also bridged. If bank stabilization is necessary, we recommend that the use of riprap be minimized and that a riprap-free buffer zone be maintained under the bridge to allow for wildlife movement. Longer bridge spans also cost far less than a separate wildlife crossing under an existing roadway. In addition, floodplain culverts must be installed if fill is placed in the floodplain for bridge construction. If a bridge is not possible and culverts are the only option, we suggest using bottomless culverts. Bottomless culverts do not need to be buried, thereby preserving the natural creek substrate and not disturbing the streambed. Culverts should be sufficiently sized to mimic natural stream functions and habitats located at the crossing site; allow for water depth, volume (flow), and velocity levels that will permit aquatic organism passage; and accommodate the movement of debris and bed material during bank-full events. Widening the stream channel must be avoided. Consideration should be given to minimum water depth during low-flow/dry periods when designing culvert placement. Sufficient water depth should be maintained during low flows to accommodate both the upstream and downstream movement of aquatic species. Water depth inside the culvert must be adequate for fish to be completely immersed and not scraping the bottom of the stream. The culvert should be designed and installed at the same slope as the stream grade to maintain an acceptable water velocity for fish passage, and the stream substrate characteristics should be retained within the culvert. Where feasible, we recommend the use of multiple barrels (other than the base-flow barrel), placed on or near stream bank-full or floodplain bench elevation, in order to accommodate floodwaters within the stream corridor. widths should be doubled (100 feet for intermittent streams and 200 feet for perennial streams). 4J.S.

Washington Department of Fish and Wildlife, Olympia, WA. 181 pp. 4 These should be reconnected to floodplain benches as appropriate. This may be accomplished by using sills on the upstream end to restrict or divert flow to the base-flow barrel(s). If the culvert is longer than 40 linear feet, alternating or notched baffles should be installed in a manner that mimics the existing stream pattern. This should enhance the passage of aquatic life by: (1) depositing sediment in the barrel, (2) maintaining channel depth and flow regimes, and (3) providing resting places for fish and other aquatic organisms. Measures to control sediment and erosion should be installed before any ground-disturbing activities occur. Grading and backfilling should be minimized, and existing vegetation should be retained (if possible) to maintain shoreline cover for fish and wildlife. Disturbed areas should be revegetated with native grass and tree species as soon as the project is completed. The proper planning, design, and installation of stream crossings provide year-round aquatic organism passage and preserve healthy streams. We recommend the following Web site for additional information regarding stream crossing activities: http://www.stream.fs.fed.us/fishxing/pointers.html Equipment in Streams. Equipment should be kept out of streams by operating from the banks in a fashion that minimizes disturbance to woody vegetation. It should be inspected daily and should be maintained in order to prevent the contamination of surface waters from leaking fuels, lubricants, hydraulic fluids, or other toxic materials. All fuels, lubricants, and other toxic materials should be stored outside the riparian management area of the stream, in a location where the material can be contained. Equipment should be checked for leaks of hydraulic fluids, cooling system liquids, and fuel and should be cleaned before fording any stream. Erosion and Sedimentation Control. Construction activities, particularly near streams, rivers, and lakes, have the potential to cause water pollution and stream degradation if measures to control erosion and sediment are not properly installed and maintained. To effectively reduce erosion and sedimentation impacts, Best Management Practices should be designed, installed, and maintained during land-disturbing activities. A complete design manual, which provides extensive details and procedures for developing site-specific plans to control erosion and sediment and is consistent with the requirements of the North Carolina Sedimentation and Pollution Control Act and Administrative Rules, is available at http://www.dlr.enr.state.nc.us/pages/publications.html.

In March of 2010, Baker Engineering (Baker) requested our review and comments regarding possible impacts from the proposed Shopping Center Drive Alignment Project. We provided those comments on April 20, 2010, which include “no effect” determinations for federally listed species in Mecklenburg County and our concerns about impacts to Doby Creek. Since that time, the project has added an additional alignment and Baker is requesting additional review and comments on the proposed project – now called the University Pointe Boulevard Extension Project. The University Pointe Boulevard Extension Project involves the design and construction of a new connector roadway, which will begin at the intersection of IBM Drive and the James Martin Middle School Driveway, cross over 1-85, and end at a future intersection with IKEA Boulevard and University Pointe Boulevard. In addition, an alternative access road for Charlotte Mecklenburg Schools has been proposed. The access road will begin about 600 feet southeast of Neal Road on the campus of Zebulon Vance High School, cross over Doby Creek, and end at the existing traffic circle on the campus of James Martin Middle School.

Federal Endangered and Threatened Species. Your letter correctly points out that there are five federally protected species in Mecklenburg County: Schweinitz's sunflower (Helianthus schweinitzii), bald eagle (Haliaeetus leucocephalus) (currently protected through the Bald and Golden Eagle Protection Act), Smooth coneflower (Echinacea laevigata), Michaux's sumac (Rhus michauxii), and the Carolina heelsplitter (Lasmigona decorata). Biologists with your company conducted a field survey for Smooth coneflower and Michaux’s sumac on July 6-7, 2010. A survey for Schweinitz's sunflower was conducted on October 28, 2010. No individuals of any of the three species were observed throughout or adjacent to the project area and Baker has made a “no effect” determination for all three species. Suitable habitat for the bald eagle and Carolina heelsplitter is not present in the project area and similar determinations were made for these species. Based on the information provided in your letter and a review of our records, we concur with your assessment that the project, as proposed, will not affect any species federally listed as endangered or threatened.

The project involves the design and construction of a new connector roadway, which will begin at the intersection of IBM Drive and the Martin Middle School Driveway in Charlotte , NC, cross over I-85, and end at a future intersection with IKEA Boulevard and University Pointe Boulevard. In addition, an alternative access road for Charlotte Mecklenburg Schools has been proposed. The access road will begin approximately 600 feet southeast of Neal Road on the campus of Zebulon Vance High School , cross over Doby Creek, and end just east of the existing traffic circle on the campus of James Martin Middle School . As mentioned, the State Historic Preservation Office was contacted in March 2011 and March 2012 with regards to the Shopping Center Drive Alignment Project. On April 12, 2010, Baker received comments from your office stating that no known historic resources would be affected by the proposed project (ER-10-0589). Since that time the project has added the school access road as part of the alignment and a subsequent review and comment letter was sent by baker in March 2011. On March 22, 2011, Baker received comments from your office again stating that no known historic resources would be affected by the proposed project. On June 6, 2012, Baker personnel identified the location of a potential, historical grave site adjacent to the project limits near the proposed school access road. Locations of the individual graves were identified by stone markers that were set in-ground and spaced in rows. Baker personnel delineated the extent of the grave site by approximating a 10-ft buffer outside of the most distant grave makers. The attached figure shows the location of the delineated grave site with respect to the proposed project limits. Distance of the delineated grave site to the proposed project limits is approximately 16 feet. Grading for the proposed roadway is approximately 45-ft inside the proposed project limits. Approximate total distance from the delineated grave site to any grading or ground disturbing activities will be a minimum of 60-ft. The purpose of the 6/7/2012 telephone conversation was to identify any additional requirements necessary with regards the referenced project and the identified grave site. In consultation it was determined that if any indications of grave site structures or remains are anticipated to be or have been unearthed, all construction activities should stop and the North Carolina Office of State Archaeology should be contacted. If any additional requirements are necessary for this or additional historical resources associated with the project area, please contact me. file:///C|/Documents%20and%20Settings/ieckardt/Desktop/RE%206712%20phone%20conversation%20follow-up.htm[7/3/2012 2:47:24 PM] Thanks again for your time- Heath Caldwell Environmental Specialist Michael Baker Engineering, Inc. 5550 Seventy-Seven Center Drive Suite 320 Charlotte , NC 28217 D (704)665-2213 C (704)999-5279 Michael Baker Engineering, Inc. 5550 Seventy-Seven Center Dr., Ste. 320 | Charlotte, North Carolina 28217 Office: 704.665.2200 | Fax: 704.665.2201 May 20, 2015 Allen Ratzlaff US Fish and Wildlife Service Asheville Field Office 160 Zillicoa Street Asheville, NC 28801 Subject: Request Review of Biological Concurrence for Northern Long Eared Bat (NLEB) University Pointe Boulevard Extension Project (Log Number 4-2-10-126) (Formerly known as the Shopping Center Drive Alignment Project) Charlotte, NC Dear Mr. Ratzlaff, On May 21, 2012, Michael Baker International (Baker) received concurrence from the United States Fish and Wildlife Service (USFWS) that based on the information available at the time of review, the proposed extension of University Pointe Boulevard (UPB) and the creation of a new School Access Road (SAR) for James Martin Middle School (USFWS Log Number 4-2-10-126) would not affect any federally listed threatened and endangered species for Mecklenburg County, NC; therefore, fulfilling the project’s obligation to meet the requirements of Section 7(c) of the Endangered Species Act (ESA). Since that time, the USFWS listed the Myotis septentridonalis (Northern Long Eared Bat (NLEB)) as a threatened species in Mecklenburg County, NC on May 4, 2015. Due to this recent listing, Baker is requesting that the USFWS review our findings and provide additional information in reference to any potential impacts that the proposed project may have on the NLEB. Below, Baker has included a brief description of the characteristics and habitat requirements for the NLEB along with a biological conclusion regarding the potential project impact. Myotis septentrionalis (Northern Long Eared Bat) The Northern Long Eared Bat is found across much of the eastern and north central United States (US) and throughout much of the Canadian providences. During the winter the NLEB hibernates in caves, abandoned mines or similar types of structures, whereas in the summer they roost under the bark or in cavities and crevices of trees and snags. The NLEB was listed as threatened due to its potential for developing a fatal fungal disease known as white-nose syndrome (WNS), which is rapidly spreading through the South and Midwestern US. Though the primary threat to the NLEB is the contraction of WNS, certain activities are also considered a threat to the species because of their decline in population and vulnerable state. As part of the final 4(d) rule to list the NLEB as threatened, activities defined by this ruling prohibit the purposeful take and regulate the incidental take, not otherwise exempt, of the species within areas of the country affected by WNS, including buffer zones. Michael Baker Engineering, Inc. 5550 Seventy-Seven Center Dr., Ste. 320 | Charlotte, North Carolina 28217 Office: 704.665.2200 | Fax: 704.665.2201 Data Analysis Since Mecklenburg County, NC is located within the WNS buffer zone, Baker has done a cursory office review of the project area using data collected during previous field surveys and an aerial map from Google Earth dated 10/4/2014. Based on this review, a mature hardwood forest, potential habitat for the NLEB, is present within the limits of disturbance for the SAR and a small portion of the UPB extension. However, since the project’s is not located within 0.25 miles of a known population and any tree clearing conducted as part of construction will occur outside of the pup season (June 1 – July 31), a determination of “not likely to adversely affect” has been made for the NLEB. We are requesting that you review our findings and provide additional information and/or comments as necessary. We have enclosed a copy of an aerial map and a USGS topographic map that includes the proposed project site boundaries for your review. We thank you in advance for your timely response and cooperation. Please feel free to contact us with any questions that you may have concerning this project (704-665-2206).
