This application is to request authorization for the proposed improvements to the Little Sugar Creek (LSC) Greenway in association with the rehabilitation of the Carolina's Medical Center (CMC) Main Campus. One potential non -wetland water of the US (S1) was identified. The center of the project area is located at 35.200174°N,-80.837652°W. The following information is included as part of this application submittal: • Project Summary Sheet • Agent Authorization • Pre -Construction Notification Form • Permit Figures ■ Figure 1 —Vicinity ■ Figure 2 — USGS 7.5' Topo (Charlotte E) ■ Figure 3 — NRCS Soils (2019 Mecklenburg Co.

The site is the existing Little Sugar Creek Greenway. Kimley)))Horn Paget The overall project proposes to rehabilitate the Atrium CMC Main Campus, which includes the construction of two (2) hospital buildings totaling 1.14 million square feet with associated parking facilities. The proposed project also includes onsite and offsite infrastructure improvements, healing pond and gardens, and the aforementioned improvements to the existing LSC Greenway. The project seeking authorization under the NWP 14 includes the removal of the existing 8-foot wide, 0.6-mile long greenway trail and the replacement with a 12-foot wide multi -use trail. The proposed trail connections will be 8-feet wide. Additionally, retaining walls are proposed along the entirety of the stream to provide long-term sustainability of the infrastructure. The existing 8-foot greenway trail was originally constructed on gabion baskets. Over time, these baskets have been degrading and the stone has been washing away causing the trail to be undermined and/or compromised in areas, resulting in a high priority public safety concern. City/County staff have reinforced some of these degraded sections with shotcrete to provide a temporary solution; however, additional areas continue to be compromised. The trail replacement will be constructed to current City/County standards and proposed to remove the existing degraded/antiquated gabion wall system and replace it with an engineered wall solution. Additionally, construction of the proposed multi -use trail requires the replacement/realignment of three existing 90-degree spanned crossings over LSC with 45-degree spanned crossings necessary for continuous movement of bicycle and pedestrian traffic and overall bicycle/pedestrian safety. AGENCY CORRESPONDENCE Cultural Resources Kimley-Horn consulted the North Carolina State Historic Preservation Office (SHPO) HPOWEB GIS service on May 13, 2020. No documented architectural, historic, or archaeological sites of significance within the project boundary were identified. The Myers Park Historic District is located adjacent to the project area on East Boulevard. However, no impacts to this Historic District are anticipated. Protected Species A review of the North Carolina Natural Heritage Program (NCNHP) database on May 13, 2020, did not indicate known occurrences of threatened or endangered species within the project boundary. Additionally, pedestrian surveys conducted by Kimley-Horn on October 1, 2019, did not identify any occurrences of protected species within the property boundary. A concurrence request letter was submitted to the USFWS on May 29, 2020. A response was received on August 13, 2020, and the project will have no effect on listed species (See attached NCNHP Letter and USFWS Concurrence Request). PROPOSED IMPACTS TO JURISDICTIONAL WATERS Authorization is requested under NWP 14 to remove the existing 8-foot greenway trail and gabion walls along LSC and replace it with segmented block retaining walls and a new 12-foot multi -use trail. The project proposes temporary impacts to 3,340 linear feet of LSC within stream -side areas necessary for construction. The project does not propose any losses of waters of the US. AVOIDANCE AND MINIMIZATION A temporary stream diversion operation will be utilized to create a dry work area to facilitate the removal of the existing gabion wall and construction of the segmented block retaining wall. The stream will be diverted by the installation of a temporary cofferdam. Temporary cofferdams will consist of either stacked sandbags or jersey barriers with integrated impervious membranes to prevent stream flows Kimley>»Horn Page 3 from entering the dry work area. A dewatering pump will be utilized to maintain a dry work area. Sediment laden water will be pumped into and filtered through a geotextile dewatering sediment bag to prevent discharges of sediment downstream. Additionally, the work area will be stabilized daily to prevent incidental discharges of sediment. COMPENSATORY MITIGATION Compensatory mitigation is not proposed as part of this project since associated impacts are temporary and will be occurring within historically impacted stream -side areas. Please feel free to contact me at (704) 409-1802 if you have any questions or if additional information is necessary.

The Service submits the following comments in accordance with the provisions of the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e); the National Environmental Policy Act (42 U.S.C. §4321 et seq.); and section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act). Project Description According to the information provided your client proposes to construct undisclosed improvements along an existing greenway in Charlotte, North Carolina. You anticipate that the project will require authorization from U.S. Army Corps of Engineers for unavoidable impacts to streams and/or wetlands. However, impacts to jurisdictional features were not described, nor were measures to avoid or minimize potential impacts. The project area occurs in an urban setting. Onsite habitats are significantly disturbed due to a legacy of adjacent development activities. Federally Listed Endangered and Threatened Species According to Service records, suitable summer roosting habitat may be present in the project area for the federally threatened northern long-eared bat (Myotis septentrionalis). However, the final 4(d) rule (effective as of February 16, 2016), exempts incidental take of northern long-eared bat associated with activities that occur greater than 0.25 miles from a known hibernation site, and greater than 150 feet from a known, occupied maternity roost during the pup season (June 1 — July 31). Based on the information provided, the project (which mayor may not require tree clearing) would occur at a location where any incidental take that may result from associated activities is exempt under the 4(d) rule. Although not required, we encourage the Applicant to avoid any associated tree clearing activities during the maternity roosting season from May 15 — August 15. Your correspondence indicates that suitable habitat is present onsite for the federally endangered Michaux's sumac (Rhus michauxii), Schweinitz's sunflower (Helianthus schweinitzii), and smooth coneflower (Echinacea laevigata). However, surveys conducted in October 2019, did not detect evidence of these species at that time. Based on these negative survey results and/or apparent lack of suitable habitat, we have no concerns for project -mediated impacts to these or any other federally protected species. Please be aware that obligations under section 7 of the Endangered Species Act must be reconsidered if: (1) new information reveals impacts of this identified action that may affect listed species or critical habitat in a manner not previously considered, (2) this action is subsequently modified in a manner that was not considered in this review, or (3) a new species is listed or critical habitat is determined that may be affected by the identified action. We offer the following recommendations in the interest of protecting fish and wildlife resources: Erosion and Sediment Control To the extent that is feasible, measures to control sediment and erosion should be installed before any ground -disturbing activities occur. Grading and backfilling should be minimized, and existing native vegetation should be retained (if possible) to maintain riparian cover for fish and wildlife. Disturbed areas should be revegetated with native vegetation and/or organic material as soon as the project is completed. Ground disturbance should be limited to what will be stabilized quickly, preferably by the end of the workday. If erosion control matting is required, only natural fiber matting (coir) should be used as synthetic netting can trap animals and persists in the environment beyond its intended purpose. Pollinator Habitat Pollinators, such as most bees, some birds and bats, or other insects, including moths and butterflies, play a crucial role in the reproduction of flowering plants and in the production of most fruits and vegetables. Declines in wild pollinators are a result of loss, degradation, and fragmentation of habitat and disease; while declines in honey bees has also been linked to disease. The rusty -patched bumble bee (Bombus afnis) historically occurred in North Carolina's Mountain and Piedmont provinces. Although not required, we encourage the Applicant to consider our recommendations below to benefit the rusty -patched bumble bee and other pollinators. Moreover, the creation and maintenance of pollinator habitats at this site may increase the value of the project for the community and help reduce the spread of invasive exotic plants. Please consider the following: 1. Sow native seed mixes in disturbed areas or in designated pollinator areas with plants that bloom throughout the entire growing season. 2. Taller growing pollinator plant species should be planted around the periphery of the site and anywhere on the site where mowing can be restricted during the summer months. Taller plants, left un-mowed during the summer, would provide benefits to pollinators, habitat to ground nesting/feeding birds, and cover for small mammals. 3. Low growing/groundcover native species should be planted in areas that need to be maintained. This would provide benefits to pollinators while also minimizing the amount of maintenance such as mowing and herbicide treatment. Milk weed species are an important host plant for monarch butterflies. 4. Avoid mowing of flowering plants. Designated pollinator areas show be mow only 50% of the plant height, but no lower than 8 inches. 5. Avoid mowing outside the active season for rusty -patched bumble bee and other pollinators (April 15 — October 15). 6. Leave slash piles, mulch piles, or loose dirt piles along woodland edges. These areas provide nesting habitats and/or nest materials for some pollinators. 7. Avoid the use of pesticides and specifically neonicotinoids. 8. Additional information regarding plant species, seed mixes, and pollinator habitat requirements can be provided upon request. The Service appreciates the opportunity to provide these comments. Please contact Mr. Byron Hamstead of our staff at byron_hamstead@fws.gov, if you have any questions. In any future correspondence concerning this project, please reference our Log Number 4-2-20-388.
