Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The project area consists of single and multi-family residences with maintained lawns and a powerline right-of-way (Figure 3, attached). The surrounded areas consist of single family residential areas and commercial properties. Typical on-site Quercus phellosLiquidambar styracifluaPinus vegetation within the project area include willow oak (), sweetgum (), Virginia pine ( virginianaQuercus rubraLigustrum sinenseUlmus alata ), northern red oak (), Chinese privet (), winged elm (), eastern redcedar Juniperus virginianaVitis rotundifoliaSmilax rotundifoliaHedera helix (), muscadine (), greenbrier (), and English ivy (). The Solidago altissimaRubus argutus powerline right-of-way is dominated with species such as tall goldenrod (), blackberry (), and Ampelopsis brevipedunculata porcelain berry (). 3b. List the total estimated acreage of all existing wetlands on the property: 0 acre of jurisdictional wetland area 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 313 linear feet of perennial stream, 231 linear feet of intermittent stream. 3d. Explain the purpose of the proposed project: The purpose of the project is to redevelop the property into a multi-family apartment complex. This project will help meet the increasing demand for housing in an area of Charlotte which is expanding due to the proximity to the light trail and uptown. Impacts to on-site jurisdictional waters are proposed in order to provide access to the proposed development. 3e. Describe the overall project in detail, including the type of equipment to be used: (see next page) Page 3 of 16 PCN Form – Version 1.4 January 2009 3e. Redeveloping the property into a multi-family apartment complex will result in unavoidable impacts to jurisdictional stream channel (Stream A). Impacts to Stream A are the result of the construction of one road crossing in order to provide sufficient ingress and egress for traffic and emergency vehicles throughout the development. The proposed culvert installation will result in 58-linear feet loss of jurisdictional waters. The proposed rip rap apron downstream of the culvert will result in an additional 26 linear feet of permanent impact but no loss of jurisdictional waters. Grading upstream of the proposed culvert and concrete turndown for the inlet protection will result in an additional 15 linear feet of permanent stream impacts. The culvert design will maintain the upstream/downstream hydrologic connection and the aquatic life passage of Stream A with the culvert bottom being buried below streambed elevation. Figure 9 depicts the proposed plan and profile view of the proposed road crossing. Stream Impacts (S1-S3) – Stream A The proposed road crossing is located in the southeastern portion of the property. Culvert installation and riprap apron placement associated with the road crossing construction will result in 84 linear feet of permanent impacts to Stream A (Figures 8 and 9, attached). To construct the proposed road crossing, a 46-linear foot, 8-foot by 4-foot reinforced box culvert will be installed, resulting in 58 linear feet of permanent impacts to Stream A (S1). The proposed culvert will be buried a minimum of one foot below the channel bed to allow passage of aquatic life and maintain low flows. Headwalls at the inlet and outlet of the culvert will be utilized in order to minimize channel impacts to the maximum extent practicable. Placement of a riprap apron at the culvert outlet will result in an additional 26 linear feet of permanent impact (S2). Grading upstream of the proposed culvert and concrete turndown for the inlet protection will have 15 linear feet of additional impacts to Stream A (S3). The placement of riprap is necessary to prevent erosional forces from undermining the culvert inlets and outlets, as well as maintain the integrity of the road crossing. A plan view and profile view of the proposed culvert are attached as Figure 9. On September 15th, Mr. Alan Johnson provided comments through email regarding the culvert design. Per his comments, the culvert diagram now shows sills at the inlet and outlet. Culvert profile also now indicates that the culvert will be backfilled. Additionally, upon installation the stream bed, immediately above and below the inlet outlet will be brought back to original stream elevation. Typical construction equipment such as tract hoe will be used. Page 4 of 16 PCN Form – Version 1.4 January 2009 4. Jurisdictional Determinations 4a.

In order to avoid and minimize the impacts to the jurisdictional waters of the U.S., the Metro South site was delineated prior to developing the site plan and the proposed site plan was designed around the delineation results. Proper sediment and erosion control measures will be used to minimize disturbances to downstream waters. Construction activities and impacts to on-site jurisdictional waters of the U.S. will comply with all conditions of Nationwide Permit 29 and Water Quality Certificate No. 4092. No Build Alternative In an attempt to minimize impacts to jurisdictional waters while meeting the goals of the project, a “No Build” alternative was considered. The property is being purchased for the purpose of providing more residential housing to meet the growth and demand of an area in Charlotte experiencing significant population growth. A “No Build” option would not meet the project goals of providing necessary housing to meet the current demand. Therefore, the No Build Alternative was eliminated from further consideration. The connection from Weona Avenue to Hollis Road is being required through the City of Charlotte's rezoning conditions. In order to make this connection, the stream must be crossed. The proposed roadway corridor is restricted by the property line and the existing end of Weona Avenue where the connection must occur to meet the rezoning conditions. With the existing end of Weona Avenue’s close proximity to the stream, it is not possible to divert the proposed roadway around the stream and still meet roadway design criteria. Headwalls 7’ in height on upstream and downstream side will be utilized to minimize impacts. Additionally, the elevation of the road was lowered to further reduce the footprint of the crossing. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Proper sediment and erosion control measures will be used to minimize disturbances to downstream waters. Construction activities and impacts to on-site jurisdictional waters of the U.S. will comply with all conditions of Nationwide Permits 29 and Water Quality Certificate No. 4092.

Endangered Species and Designated Critical Habitat (Corps Requirement) 5a. Will this project occur in or near an area with federally protected species or Yes No habitat? 5b. Have you checked with the USFWS concerning Endangered Species Act Yes No impacts? Asheville 5c. If yes, indicate the USFWS Field Office you have contacted. 5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat? CWS scientists performed a data review using North Carolina Natural Heritage Program (NCNHP) Data Explorer on July 12, 2017 to determine the presence of any federally-listed, endangered species, threatened species, or critical habitat located within the project area. Based on the NCNHP review, there are no records of federally-protected species within the project limits or within a mile of the project area. A copy of the NCNHP report is attached (Attachment I). The United States Fish and Wildlife Service’s (USFWS) Records of Endangered, Threatened, and Species of Concern list for Mecklenburg County was reviewed. The USFWS database lists the Schweinitz’s sunflower (Helianthus schweinitzii), Michaux’s sumac (Rhus michauxii), smooth purple coneflower (Echinacea laevigata), Carolina heelsplitter (Lasmigona decorata), rusty-patched bumble bee (Bombus affinis), and bald eagle (Haliaeetus leucocephalus) as potentially occurring in Mecklenburg County (Table 1, next page). Additionally, the project area is within northern long-eared bat (Myotis septentrionalis) range. Prior to the field work, CWS scientists visited a known population of Helianthus schweinitzii on July 10, 2017 to determine the condition of its stem, leaves, and flowers. Based on the site visit, the aboveground plant parts are identifiable but flowers were present. On July 10, 2017, CWS scientists conducted a pedestrian survey of the project area for federally- protected species. Transects were completed within identified areas of supportive habitat, as applicable, for potentially occurring federally-protected species. Potential habitat was observed for the rusty-patched bumble bee but no individuals were identified within the project limits. Therefore, the proposed project May Affect, is Not Likely to Adversely Affect the rusty patched bumble bee. However, the USFWS is currently considering all occurrences of rusty-patched bumble bee to be historic and are not requiring surveys at this time. Based on the literature search and the results of the on-site assessment for Schweinitz's sunflower, Michaux's sumac, Smooth purple coneflower, Carolina heelsplitter, Bald Eagle, it has been determined that no habitat was observed for the aforementioned federally protected species. Therefore, this project will have no effect on these species. Additionally, any incidental take on NLEB that may result from associated activities is exempt under the 4(d) rule. A letter requesting concurrence was sent to the USFWS on July 17, 2017. In their response letter, the USFWS concurred with CWS findings (Attachment J). 6. Essential Fish Habitat (Corps Requirement) 6a. Will this project occur in or near an area designated as essential fish habitat? Yes No 6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat? NOAA Fisheries: http://www.habitat.noaa.gov/protection/efh/habitatmapper.html 7. Historic or Prehistoric Cultural Resources (Corps Requirement) 7a. Will this project occur in or near an area that the state, federal or tribal governments have designated as having historic or cultural preservation Yes No status (e.g., National Historic Trust designation or properties significant in North Carolina history and archaeology)? Page 15 of 16 PCN Form – Version 1.4 January 2009 7b. What data sources did you use to determine whether your site would impact historic or archeological resources? A letter was forwarded to the North Carolina State Historic Preservation Office (SHPO) on June, 2015 to determine the presence of any areas of architectural, historic, or archaeological significance that would be affected by the project. CWS also consulted the SHPO online GIS service and found no historical structures, buildings, sites, or districts within the project limits. In a response letter, dated June 29, 2015, SHPO stated that they are “aware of no historic resources which would be affected by the project” (Attachment H). 8. Flood Zone Designation (Corps Requirement) 8a. Will this project occur in a FEMA-designated 100-year floodplain? Yes No 8b. If yes, explain how project meets FEMA requirements: There will be no fill in the FEMA floodplain. Additionally, the extents of grading will be outside of the FEMA floodplain. 8c. What source(s) did you use to make the floodplain determination?
