Salisbury St., 9th Floor Raleigh, NC 27604 Subject: Pre -Construction Notification Pursuant to Nationwide Permit Nos. 27 and 29 Cheyney Charlotte, North Carolina CWS Project No. 2018-0103 Dear Mr. Shaeffer and Mr. Johnson, The Cheyney site is approximately 163 acres in extent and is located east of the Independence Hill Road and Arthur Davis Road intersection in unincorporated Mecklenburg County, North Carolina (Figures 1 and 2, Attachment A). Mattamy Homes has contracted Carolina Wetland Services, Inc. (CWS) to provide Section 404/401 permitting services for this project. An executed Agent Authorization Form is attached (Attachment B). CWS is submitting a Pre -Construction Notification pursuant to Nationwide Permit No 29 to the U.S. Army Corps of Engineers for proposed permanent impacts to the jurisdictional waters of the U.S. associated with developing the subdivision into a single-family development. In addition, the project proposes draining a on-site pond and restoring the stream at the location of the current pond, which will be permitted under NWP 27. The impacts from this project were counted cumulative to the adjoining Meridale subdivision. Therefore, mitigation is proposed for this project. Since the project will also result in ecological uplift due to the proposed stream restoration, Mattamy Homes proposes 1:1 ratio to mitigate for these wetland impacts. A Request for Preliminary Jurisdictional Determination was submitted to the USACE on April 7, 2018 (SAW -2006-41171) and the on-site features were field verified by Mr. David Shaeffer of the USACE on June 8, 2018. A copy of the PCN application is being provided to the North Carolina Division of Environmental Quality (NCDEQ) with a check of $570 for the 401 Water Quality Certification approval fee.

Project Description 3a. 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 property is approximately 163 acres in extent and is located east of the Independence Hill Road and Arthur Davis Road intersection in unincorporated Mecklenburg County, North Carolina (Figures 1 and 2). Current land use consists of forested and agricultural land with a residential house and farming structures. Surrounding land use consist of single-family subdivision, forested areas, and agricultural land. Interstate 485 is located along the northern property boundary (Figure 3). According to the United States Department of Agriculture - Natural Resources Conservation Service (USDA-NRCS) USDA- NRCS Soil Survey of Mecklenburg County (Figures 4 and 5) on-site soils consist of ten different soil units. Of the on-site soils, only Monacan loam is listed the Web Soil Survey database as containing hydric inclusions. There are several jurisdictional waters of the U.S. located within the property. These waters consist of seven jurisdictional stream channels (Streams A -G), nineteen jurisdictional wetlands (Wetlands AA-QQ), and four jurisdictional ponds. There are several old stream crossings located within the Cheyney property. These old crossings were permitted under non - notifying NWP26 and are further discussed in Section 5b in this PCN. 3b. List the total estimated acreage of all existing wetlands on the property: 0.457 acre wetland, 1.2 acre pond 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 4,528 linear feet of perennial stream, 772 If intermittent stream 3d. Explain the purpose of the proposed project: The purpose of this project is to develop the property into a single-family residential subdivision. This project will provide residential housing for Charlotte, North Carolina to meet the growing demand for housing due to population growth. Page 3 of 14 PCN Form — Version 1.4 January 2009 3e. Describe the overall project in detail, including the type of equipment to be used: The project proposes developing the site for a single-family residential development. Construction of this project will require one road crossing over stream and two small wetlands and three open trench sewerline crossings. Fill for a road will result in 0.019 acre of permanent impacts to Wetlands AA and BB (W1 and W2) and 38 If permanent impacts to Stream A (S1). The three open trench sewerline crossings would permanently impact 30 linear feet of stream bank due to rip rap bank stabilization and temporarily impact 120 linear feet of stream channel (S2 -S7). Additionally, the project proposes draining the Pond A and restoring Stream E at the location of the current pond. The site plan and impact drawings are included as an Attachment D. The Pond Draining and Stream Restoration Plan is included as an Attachment E. Road Crossing (S1, W1 -W2) The proposed road crossing is necessary to connect the southwestern portion of the subdivision to the rest of the property. Due to City of Charlotte set back requirements and as the begin of these jurisdictional features fall close to the property boundary, the grading fill for the proposed road crossing must permanently impact 38 linear feet of Stream A (S7), 0.013 acre of Wetland AA (W1), and 0.006 acre of Wetland BB (W2). The proposed impacts to jurisdictional waters of the U.S. are minimal and required due to limited space between the rail road set back and existing wetlands. Open Trench Sewerline Crossings (S2 -S7) Three open trench sewerline crossings are required for this project as the soils are too shallow at these locations to allow directional boring methods. Each sewerline crossing will temporarily impact 40 linear feet of stream due to sewerline installation, temporary fill due to dewatering system, and bank stabilization. Additionally, each crossing will permanently i 10 linear feet due to stabilization with rip rap along the bank, extending below the ordinary high water mark. All work will be completed in dry and the temporary dewatering system will be removed after the work has been completed. The pump -around system details are included in Exhibit 7 (Attachment D). The disturbed stream bed will be returned to the existing grade and the stream banks will be graded to 2:1 slope, matted, and stabilized with seeding and live stakes. The wic of the rip rap along the stream bank will be limited to 10 linear feet. The bank stabilization details are depicted in Exhibits 7-8 (Attachment D). Pond Draining and Stream Restoration The project will include draining Pond A within the Cheyney development site followed by excavation of the earthen dam to remove the primary outlet structure. UT -Clarks Creek will be restored within the old pond footprint. Stream restoration will be performed in the dry. The restored stream channel will be constructed as a Rosgen classified B5 channel using log and rock structures for grade control, building bankfull benches, and providing access to flood prone areas. Streamside and riparian vegetation will be installed, and the old lake bed will be stabilized by seeding and matting. Stream restoration length will total 624 linear feet. An additional 40 linear feet of bank stabilization is proposed on the lower end of the stream restoration construction corridor. Due to uncertainties regarding specific characteristics of the pond bed, some field adjustments may be needed to the stream restoration plan following draining of the lake. Any major changes will be coordinated with the agencies prior to implementation. Typical heavy equipment will be used in the grading operations (bulldozers, excavators, dump trucks, graders, etc.). The Pond Removal and Stream Restoration Plan is found in Attachment E. Page 4 of 14 PCN Form — Version 1.4 January 4. Jurisdictional Determinations 4a. Have jurisdictional wetland or stream determinations by ❑ Yes ❑ No ❑x Unknown the Corps or State been requested or obtained for this property/ project including all prior phases in the Comments: 4b.

Agency/Consultant Company: Name (if known): Other: CWS 4d. If yes, list the dates of the Corps jurisdictional determinations or State determinations and attach documentation. A Request for Preliminary Jurisdictional Determination was submitted to the USACE on April 7, 2018 (SAW -2006-41171). The on-site features were field verified by Mr. David Shaeffer of the USACE on June 8, 2018. No verification letter has been received from the USACE as the date of this PCN submittal. 5. Project History 5a. Have permits or certifications been requested or ❑x Yes ❑ No ❑ Unknown obtained for this project (including all prior phases) in 5b. If yes, explain in detail according to "help file" instructions. The adjoining subdivision, Meridale, resulted in approximately 0.087 acre of permanent wetland impacts (SAW -2007-01172). These impacts are counted cumulatively with this permit. The same permit authorized also a permanent stream impact associated with a road crossing, but a site inspection revealed that a bottomless culvert was installed instead of a previously permitted box culvert, resulting in no permanent impacts to jurisdictional stream channels. The cumulative impact analysis, old permit verification with impact figures, and pictures of the bottomless culvert for the Meridale site are included as an Attachment F. Additionally, there are nine old stream crossings located within the Cheyney property. As these crossings were put in place prior to 2000 and the acreage of the stream impacts was approximately 0.03 acre (below the one acre notification threshold), they were permitted under non -notifying NWP26. 6. Future Project Plans 6a. Is this a phased project? ® Yes ❑ No 6b. If yes, explain. The Cheyney project consist of four phases as depicted in the overview map. All four phases are included to this permit application. This project will not result in additional phases in foreseeable future. The Cheyney is not another phase to the adjoining Meridale project. The Meridale was originally developed by different developer and the Cheyney site has independent utilities and access. However, as these two subdivisions are both currently owned by Mattamy Homes and share connecting road, the impacts are treated cumulatively. Page 5 of 14 PCN Form — Version 1.4 January 2009 C.

Impact Justification and Mitigation 1. Avoidance and Minimization 1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. To avoid and minimize impacts to jurisdictional waters of the U.S., the Cheyney site was delineated prior to finalizing the site plan. Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent practicable while still meeting the project goals. The proposed permanent impacts associated with this project are minimal and draining the pond in order to restore the stream will provide ecological uplift. The number of open trench sewerline crossings is limited to three and jack -and -bore crossings were utilized whenever possible. The open trench crossings are in an area where the soil is too shallow to allow directional boring methods. The proposed development will avoid most on-site jurisdictional waters. However, a proposed 0.019 acre permanent wetland impact and 38 linear feet permanent stream impacts are required to provide street connectivity and comply with City of Charlotte ordinances. Based on the City of Charlotte set back requirements and required road network connectivity, avoiding the impacts to wetlands would have adverse impacts on the site layout. 1 b. 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. Silt fence will be installed around the jurisdictional features, outside of the avoided wetlands, streams and ponds. Construction activities and impacts to on-site jurisdictional waters of the U.S. will comply with all conditions of Nationwide Permit Nos. 27 and 29. All work will be completed in dry and the temporary dewatering system will be removed after the work has been completed. The disturbed stream bed will be returned to existing grade and the stream banks will be graded to 2:1 slope, matted, and stabilized with seeding and live stakes. No rip rap will be placed in the streambed other than along the banks below the ordinary high watermark for the sewerline crossings. The width of the rip rap along the stream bank will be limited to 10 linear feet. The proposed sewerline construction corridors are wider than 40 ft. Installing the sewerline per the specifications and the required by-pass pumping will require a wider corridor. However, the proposed impacts for each of the crossings are limited to 50 If. 2.

A historic impoundment (Pond A) with an earthen dam, along Perennial RPW Stream E (UT -Clarks Creek), is proposed to be removed. Pond A is approximately 1.1 -acres in extent. Mattamy Homes proposes to drain the pond, remove the dam, and perform a stream restoration. Removal of the pond and restoration of the stream reach will remove an existing aquatic fauna migration barrier and eliminate hazards associated with the dam structure. The purpose of this project is to reconstruct and stabilize stream channel and adjoining riparian and flood prone areas within the pond removal footprint. Ecosystem enhancement will involve draining the pond, removing the existing dam, and restoration of the previously existing stream impounded within the pond footprint and a short section below the pond. Stream channel characteristics above the pond were surveyed and identified using the Rosgen Level II Classification methods. Two adjacent stream reaches were identified as stable and will be used as references for the stream restoration design. Reference reaches 1 and 2 were field surveyed, collecting existing morphological data used to classify the stable stream system and to create reference figures and tables. This Stream Restoration Plan includes a current conditions geomorphic assessment, designs, plans for the restoration and ecosystem enhancement of Perennial RPW Stream E, and a monitoring plan to show Nationwide Permit (NWP) 27 ecological uplift requirements. The proposed design is intended to reconstruct a stable stream channel for approximately 642 -linear feet. The stream restoration activity will be within the footprint of Pond A, and it will include daylighting stream channel along the existing 80 -linear foot pond outfall pipe, as well as, an additional 20 -linear feet of stream channel directly below the pond outfall pipe to create a stabilized channel tie-in with grade control structure. Directly below the stream restoration tie-in point, an approximate 40 -linear foot section of stream bank along the right stream side will be stabilized using natural stream design techniques. Relevant regional curve and reference data will be utilized in the stream design. Newly constructed stream channel, flood prone and riparian areas will be stabilized using bioengineering and natural channel design approaches and techniques. Existing Conditions Site Assessment A site visit and geomorphic survey was performed by CWS scientists Sean Martin, Senior Project Scientist, and Hannah Meeler, Staff Scientist, on October 23, 2018. The survey included a longitudinal profile (--160 ft.) and cross-sectional surveys (8 cross-sections: 4 riffles and 4 pools) of ecological reference Stream E (Attachment A). The geomorphic assessment of Perennial RPW Stream E also included substrate 3of11 Cheyney Residential Subdivision October 31, 2018 Pond Removal and Stream Restoration Plan CWS Project No. 2018-0103 sampling (Wolman reach -wide pebble count) and photographic documentation. This data was used to classify Perennial RPW Stream E using the Rosgen Level II system. A vegetative survey was conducted to describe on-site vegetation and aid in restoring the riparian buffer and forest. Site Description The project site surrounding area consists of undeveloped forested areas, agricultural land, and residential subdivisions. Typical on-site vegetation consists of black cherry (Prunus serotina), eastern red cedar (Juniperus virginiana), elderberry (Sambucus nigra), green ash (Fraxinus pennsylvanica), sweetgum (Liquidambar styraciflua), American sycamore (Platanus occidentalis), red maple (Acer rubrum), tag alder (Alnus serrulata), black willow (Salix nigra), tulip poplar (Liriodendron tulipifera), Chinese privet (Ligustrum sinense), greenbrier (Smilax spp.), Japanese honeysuckle (Lonicera japonica), jewelweed (Impatiens capensis), poison ivy (Toxicodendron radicans), Nepalese browntop (Microstegium vimineum), red deadnettle (Lamium purpureum), pokeberry (Phytolacca americana), Virginia creeper (Parthenocissus quinquefolia), woolgrass (Scirpus cyperinus), sawtooth blackberry (Rubus argutus), soft rush (Juncus effusus), spotted ladysthumb (Polygonum persicaria), and various sedges (Carex spp.). Bankfull Verification Indicators of bankfull levels were identified in the field and included scour lines, floodplain benches, and the backs of depositional bars. The observed bankfull cross-sectional areas of the reference reaches were verified using the drainage area for each reach, and the North Carolina Piedmont regional curves (Table 1 and Appendix A). From the 8 reference cross-sections measured, just 2 of the observed bankfull cross-sectional areas fall within the 95% confidence interval for the Rural Piedmont North Carolina regression line (Cross-sections 1 and 3). This is most likely because the flow of the reference reach is controlled by backwater from the downstream pond, as well as, multiple piped sections upstream of the reference reaches and other online ponds. The rural curve was used because less than 15% of watershed surface area is impervious.' Locations of cross sections were chosen at areas that represent the overall character of the reach. Cross-sectional measurements were not taken within two bankfull widths of bedrock outcrops or other in -stream structures for consistency with current methodology. In -stream structures alter the flow and velocity of the channel resulting in the presence of non -representative bankfull indicators. The cross sections were chosen to be the most representative within each reach, with the least amount of existing disturbance. Table 1.

Geomorphic Assessment Perennial RPW Stream E originates on-site below the confluence of two headwater stream channels. The eastern stream channel originates at an onsite online pond (Pond D), and the western stream channel originates from a headwater forested wetland (Wetland 00). The flow of Perennial RPW Stream E is influenced by upstream on-site ponds (Ponds B -D). The assessment area involved two stream ecological reference reaches upstream of the proposed pond removal (Pond A). Longitudinal profiles, cross-sections, and the Rosgen classification are discussed below. Ecological Reference Reach Geomorphic and Stability Assessment Approximately 160 linear feet along Perennial RPW Stream E, immediately upstream of Pond A, was surveyed and utilized as a reference (Reaches 1 & 2 - Exhibit 1). The Rosgen Level II classification for the reference reach was identified as B5 based on slight to moderate entrenchment and width to depth ratios. The reference reaches exhibit substrate consisting of coarse sand (D50 =0.2 mm). The average drainage area for this reach is approximately 0. 129 square miles (82.6 acres). The valley slope averages 2%, bankfull slopes average 1.5%, and sinuosity averages 1.35. Mean bankfull width and depth for the reaches are 6.125 feet and 0.34 feet, respectively. The field measured average bankfull cross-sectional area for these reaches is 3.56 sq. feet. The average width of flood -prone areas is 9.145 ft. These data are summarized in Table 2. Photographs of the reference reach are included in the Pre -Construction Notification.

CWS developed a stream design for the removal of Pond A and restoration of Perennial RPW Stream E based on existing channel conditions of reference reaches and regional curve data. This design will improve the goals of the Cheyney project and enhance future water quality by removing stagnant stratified substrate, increasing the quality of epifaunal substrate, increasing the health and diversity of suitable aquatic habitats, and enhancing the riparian plantings. The old pond bed will be filled and planted with native riparian species. Typical cross-sectional dimensions will be based on the existing cross sectional dimensions of the reference reach (Attachment A), as well as, regional curve data. A longitudinal profile will be developed for the restored stream that will tie-in to the existing channel above Pond A and below the outfall pipe on Pond A. Reference and regional curve data (Attachment A) will be used to layout the longitudinal profile within the proposed stream construction corridor specifying pool -to -pool spacing, riffle -to -riffle spacing, riffle and pool slopes, depths, and lengths. Completing the stream restoration within the pond footprint will include field locating and utilizing existing natural grade control to the extent practically feasible. The proposed longitudinal profile (Figure D) is based on regional curve and reference data and will be built using field identified features such as grade control and consolidated natural ground. This will involve field adjustments to design where conditions are found to be most suitable and exclude areas with conditions found to not fit with the proposed plan. 2 North Carolina Stream Mitigation Guidelines. 2003. http://porta1.ncdenr.org/c/document_library/get_file?uuid=ab4ccad4-5cbe-45f3-979f-ab3fe35d21 a1 &groupId=61581 6of11 Cheyney Residential Subdivision October 31, 2018 Pond Removal and Stream Restoration Plan CWS Project No. 2018-0103 Dam Removal The project grading contractor will drain the pond using NCDEMLR pond removal protocols to avoid sediment discharges to downstream waters and to protect water quality. Water drawdown rates will be adhered to and proper dewatering designs will be utilized to minimize erosion and sediment loss. Following the pond draining activity, the entire pond bed will be hydro -seeded with a temporary erosion control mix. Temporary inlet protection will be installed around the existing outfall pipe to reduce sediment input into the outfall system while work proceeds and site conditions become stabilized. The earthen dam will be removed through excavation activities utilizing typical heavy machinery. Erosion control measures will be employed to ensure sediments are isolated and prevented from entering downstream waters. Once the earthen dam is removed, stream flow will be intercepted at the upstream portion of the dam and stream restoration construction corridor and piped around the entire construction corridor. The pond outfall pipe will then be removed and stream restoration channel work will commence. Ecological Uplift The ecological value of Pond A is currently very limited. This impoundment is filled with sediments and is limited in habitat diversity and biodiversity. Removing the dam and restoring the stream system will provide an overall ecological uplift to the ecosystem by providing diverse habitat for a variety of aquatic species and improve downstream water quality. A biological assessment of the pond and ecological reference reach revealed a low variety and abundance of species utilizing the pond, while a higher abundance and variety of species were utilizing Perennial RPW Stream E. The impoundment of Perennial RPW Stream E will be enhanced through the construction of narrow bankfull benches, laying back of banks to a 3:1 slope or flatter, and the installation of in -stream structures to improve the profile of the channel. A moderately sinuous channel pattern will be designed through the thalweg of the pond. The remaining previously ponded area will be planted with riparian vegetation and serve as flood -prone benches and potential wetland complexes. The unimpounded channel with access to wider flood -prone benches will decrease shear stress within the channel and will reduce downstream bank erosion and sediment input. Cross -vanes will also be used, as necessary to provide vertical channel stability. Live stake and bare root woody vegetation will be used to promote bank stability on the outside of meander bends. The restored channel reach is designed to have a profile and dimension similar to the upstream reference reaches. The restored stream will have similar channel stability and dimensions to the reference reach and the regional curve data, as well as, provide an uplift to aquatic function by providing a higher quality riparian buffer by improving access to the floodplain, adding riparian habitat, restoring riparian wetland connectivity, reducing thermal pollution, and returning the system to native environmental conditions. The improvements to the impounded ecosystem are designed to minimize downstream erosion, sediment accumulation, and scouring by redirecting flow and reducing shear stress during high flow events. 7of11 Cheyney Residential Subdivision October 31, 2018 Pond Removal and Stream Restoration Plan CWS Project No. 2018-0103 Stream Design A stream design was developed for the impounded portions of Perennial RPW Stream E based on the existing upstream reference reaches of the stream. Figure D shows typical cross-sections for riffle and pool sections of the proposed stream design. The dimensions of the proposed new channel are given in Table 3. The proposed channel pattern and profile are also shown on Figure D. Table 4 summarizes the proposed stream reach data and is shown below. Table 3: Proposed Channel Dimensions in feet.

An approximate 40 -foot section of stream bank along the right stream side will be stabilized using natural stream design techniques. These techniques 8of11 Cheyney Residential Subdivision October 31, 2018 Pond Removal and Stream Restoration Plan CWS Project No. 2018-0103 will include grading the streambank to a stable slope (2:1 to 3:1), matting, seeding, and planting livestakes. Attached is a typical cross-section view of the proposed bank stabilization work (Figure E). Monitoring Plan Mitigation is not required for this project, therefore, no USACE or NCDEQ official monitoring program will be executed for this project. However, in order to ensure the success of the proposed ecological uplift required by NWP 27, the proposed stream restoration will be monitored every other year over a five year period beginning from the completion of the work for a total of three monitoring events. Monitoring techniques and practices will be adapted from the USACE and NCDEQ Stream Mitigation Guidelines for North Carolina.3 Qualitative monitoring data for vegetation survival analysis, habitat assessments, and channel stability analysis will be gathered and photo documented in order to assess the variety of aquatic resource functions and services the restored stream system will provide to the area. The monitoring event will be conducted during mid -growing season. The report will include photographs, rapid assessment vegetation survival counts, stream stability documentation, and a short narrative describing current site conditions as they relate to aquatic habitat function. Photographs will be taken from no fewer than four established monitoring positions. The exact locations will be determined, marked with a stake, and recorded with a GPS receiver in the field immediately following as -built completion and used in the following monitoring event. Upon completion of the project, an as -built channel survey will be conducted. The survey will document the dimension, pattern, and profile of the restored channel. Six permanent cross-sections will be established at an approximate frequency of one per 20 bankfull-width lengths (approximately one for every 100 feet of channel). The selection of locations will include areas that may be predisposed for potential problems. The as -built survey will also include photo documentation at all cross-sections and structures, a plan view diagram, a longitudinal profile, vegetation information, and a pebble count for at least all cross-sections. The longitudinal profile will include the entire length of the restored stream channel. Vegetation survival counts will be collected from established plots within each monitored area. The plot locations will be randomly determined in the office using GIS. The plots for stream restoration sites extend from the toe of bank to the furthest edge of the outside planting zone. The total area of plots is equal to 10% of the specific restoration site. Monitoring data collected will include the following: • reference photos (before and after) • plant survival analysis • channel stability analysis • instream habitat analysis 3 USACE 2003. Stream Mitigation Guidelines. 9of11 Cheyney Residential Subdivision October 31, 2018 Pond Removal and Stream Restoration Plan CWS Project No. 2018-0103 Success Criteria As described above, this guidance requires three forms of monitoring to evaluate the success of the project; photo documentation, ecological function, and channel stability measurements. These criteria will be used to evaluate success by considering the following data: Channel Stability There should be insignificant change from the as -built dimensions to those measured in the field during monitoring. If changes are present the changes should be minor and represent an increase in stability (e.g. decreased width to depth ratio without a decrease in entrenchment ratio). • There should be little change from the as -built longitudinal profile. • Pool/riffle spacing should remain fairly constant. • Pools should not be filling in (aggradation) or riffles starting to change to pools (degradation). • Three permanent cross-sections should remain fairly stable. • Pebble count should show a change in the size of bed material toward the desired composition. Photo documentation • Channel aggradation or degradation • Bank erosion • Success of riparian vegetation • Effectiveness of erosion control measures • Presence or absence of developing instream bars (should be absent) Ecological Function • Health and survival of planted vegetation • Presence of instream habitat structures Planting Plan Natural coconut matting (coir matting), native seed mix, live stakes, and native plants will be installed on both sides of the restored stream in the 25 -foot wide riparian zone for bank stabilization and erosion control. Vegetation species were chosen based on the existing plant community and to add species diversity, particularly in the riparian zone. Stream banks consist of three zones: 1) lower stream banks, 2) upper stream banks, and 3) riparian buffer. Revegetation of the area directly adjacent to the restored channel is especially important to prevent erosion, downstream sedimentation, and provides important water quality and habitat services. Wetland plant species such as silky dogwood (Cornus amomum), river birch (Betula nigra), black willow (Salix nigra), and soft rush (Juncus effusus) will be planted on the lower stream banks (Zone 1). Black willow and clusters of soft rush will be planted on outside stream bends for dense rooting and erosion control. Upper stream banks (Zone 2) will be planted with other 10 of 11 Cheyney Residential Subdivision October 31, 2018 Pond Removal and Stream Restoration Plan CWS Project No. 2018-0103 moisture -tolerant species such as green ash and red maple. The riparian buffer (Zone 3) will be planted with species such as ironwood, slippery elm, and spicebush. All disturbed areas will be seeded with temporary and permanent native riparian and wetland seed mixes, and stream banks will be matted with natural coconut matting.

This permit expired September 24, 2009. Actual Impacts by 2018 Wetland Impacts: Based on historic aerial maps, authorized wetland impacts (0.087 acre) were completed prior the permit expired. These impacts will be counted cumulatively to the new proposed wetland impacts. Stream Impacts: There were two bottomless culverts located between Meridale Forest Drive and Hartington Place that run underneath Allen A Brown Road. The culvert closest to Meridale Forest Drive is approximately 79 feet long, and the culvert closest to Harington Place is approximately 62 feet long. These two bottomless culverts appeared to be installed between 2015 and 2016. Photographs 1-6 are representative of these culverts. Since the culverts that were installed are bottomless, there are no stream impacts that would be cumulative to the new proposed subdivision (currently referred as Cheyney).

Westinghouse Blvd. Charlotte, NC 28273 704-527-1177 (office) 704-527-1133 (fax) April 24, 2018 Mr. Bob Wiggins Vice President, Land Mattamy Homes 2127 Ayrsley Town Blvd., Suite 201 Charlotte, NC 28273 Subject: Protected Species Habitat Assessment Report Cheyney Mecklenburg County, North Carolina CWS Project No. 2018-0103 Dear Mr. Wiggins, Mattamy Homes has contracted Carolina Wetland Services, Inc. (CWS) to provide a protected species habitat assessment for Cheyney site. The Cheyney site (Mecklenburg County Tax Parcel Nos. 02762101, 02762102, 02761168, 02718125, 02718126, 02718185, and partial 02718103) is approximately 163 acres in extent and is located east of the Independence Hill Rd. and Arthur Davis Rd. intersection, in unincorporated Mecklenburg County, North Carolina (Figure 1). Methods In -office Desktop Review To determine which protected species are listed as occurring or potentially occurring within the project vicinity, and prior to conducting the on-site field investigation, CWS consulted the United States Fish and Wildlife Service (USFWS) Endangered and Threatened Species and Species of Concern by County for North Carolina online database for Mecklenburg County'. In addition, CWS performed a data review using the North Carolina Natural Heritage Program (NCNHP) Data Explorer on April 18, 2018 to determine if any record occurrences of federally -listed, candidate endangered, threatened species, or critical habitat are located within the project limits. Typical habitat requirements for listed species was discerned from multiple USFWS' and NCNHP' online resources including, but not limited to, specific USFWS species profiles, recovery plans, NCNHP Guide to Federally Listed Endangered and Threatened Species of North Carolina, and List of the Rare Plant Species of North Carolina.

Field Survey CWS Senior Scientist, Sean Martin, conducted a pedestrian habitat assessment of the project area on April 18, 2018. Supportive habitats for potentially occurring federally -protected species that were identified during the desktop review were assessed in the field for the quality of physical and/or biological features essential to the conservation of the applicable species. Additionally, during the pedestrian habitat assessment, areas were reviewed for the presence of federally protected species. However, formal surveys were not conducted for the occurence of protected species. Identification references for land cover types include the National Land Cover Database (2011)6. Results Based on the NCNHP data explorer review, there are no current records of federally -protected species within the project limits or within a mile of the project limits (Attachment A). The USFWS lists seven federally protected species for Mecklenburg County (Table 1). An official species list has not been obtained from the USFWS Asheville Field Office. Table 1.

A brief description of each species habitat requirements and determination of effect findings are listed below, by species. Schweinitz's sunflower (Helianthus schweinitzii) Habitat Description: Schweinitz's sunflower is a perennial herb with yellow rays and yellow centers. They can reach heights of five feet. Populations are limited to the piedmont of North and South Carolina. It has been listed as an Endangered species under the ESA since 1991. The typical habitat for this plant includes roadsides, old pastures, transmission line right-of-ways, open areas, either natural or human -maintained habitats, or edges of upland woods. Major characteristics of soils associated with suitable Schweinitz's sunflower habitat include thin soils, soils on upland interstream flats or gentle slopes, soils that are clay -like in both composition and texture (and often with substantial rock fragments), soils that have a high shrinkage swell capacity, and those which vary over the course of the year from very wet to very dry. Biological Analysis: Potential on-site habitat for this species is limited to the fringe areas between cultivated crop fields and forested areas (Figure 3, Photograph 2, attached). The desktop review and field survey assessment found that these fringe areas do not have the proper soils to support the Schweinitz's sunflower. No individuals of Schweinitz's sunflower or other Helianthus species were observed during the field assessment on April 18, 2018. Potential habitat areas are very poor quality due to evidence of herbicide spraying activities and non-native/invasive species competition; no known population records of the species occurs within one mile of the project boundary, based on the NHP records review. These findings lead CWS to conclude that the project will not affect the Schweinitz's sunflower. Smooth coneflower (Echinacea laevi_ aceta) Habitat Description: Smooth coneflower is a tall, perennial herbaceous plant found in areas with abundant sunlight where competition in the herbaceous layer is minimal. It has been federally listed as Endangered under the ESA since 1992.$ Typical habitat for this plant includes meadows, open woodlands, the ecotonal regions between meadows and woodlands, cedar barrens, dry limestone bluffs, clear cuts, and roadside and utility rights-of-way. In North Carolina, the species normally grows in magnesium- and calcium- rich soils associated with gabbro and diabase parent material, and typically occurs in Iredell, Misenheimer, and Picture soil series. It grows best where there is abundant sunlight, little competition in the herbaceous layer, and periodic disturbances (e.g., regular fire regime, well-timed mowing, careful clearing) that prevents encroachment of shade -producing woody shrubs and trees. On sites where woody succession is held in check, it is characterized by a number of species with prairie affinities. United States Fish and Wildlife Services. 1991.

Page 3 of 8 Cheyney April 24, 2018 Protected Species Assessment Report CWS Project No. 2018-0103 Biological Analysis: A NCNHP data record review revealed no current occurrences for this species within the project limits or within a one -mile radius of the project boundary (Attachment A). Though disturbed shrub/scrub and fringe areas, conducive to early -succession species, are present in the project area, these areas consist of saprolite and residuum weathered soils, absent of magnesium and calcium, and are therefore not suitable for smooth coneflower.' No individuals of smooth coneflower were observed during the field assessment on April 18, 2018. Potential fringe habitat areas are very poor quality due to evidence of herbicide spraying activities and non-native/invasive species competition. These findings lead CWS to conclude that the project will not affect the smooth coneflower. Michaux's sumac (Rhus michauxii) Habitat Description: Michaux's sumac is a rhizomatous shrub that is densely hairy with compound leaves exhibiting evenly -serrated leaflets. Flowers are small, greenish to white, that form in terminal clusters. Fruits are red drupes produced between August and October. Michaux's sumac has been listed as an Endangered species under the Endangered Species Act (ESA) since 1989.10 It is found in the piedmont and coastal plains of Virginia to Florida, with most populations occurring in North Carolina. It prefers sandy or rocky open woods with basic pH soils, as well as, highway right-of-ways, roadsides, or edges of artificially -maintained clearings. Biological Analysis: A NCNHP data record review revealed no current occurrences for this species within the project limits or within a one -mile radius of the project boundary (Attachment A). Though disturbed open areas conducive to early -succession species are present in the project area, these areas consist of soils that are not suitable for Michaux's sumac (Figure 2). Additionally the Raleigh Ecological Services Field Office states in its Michaux's sumac profile page that the species is considered historic in Mecklenburg County11. Due to poorly supporting soils, poor quality potential habitat areas, and no known occurrences in the project region, CWS concludes that this project will not affect Michaux's sumac. Carolina heelsplitter (Lasmigona decorata) Habitat Description: The Carolina heelsplitter was historically known from several locations within the Catawba and Pee Dee River systems in North Carolina and the Pee Dee and Savannah River systems, and possibly the Saluda River system in South Carolina. In North Carolina, the species is now known only from a handful of streams in the Pee Dee and United States Department of Agriculture, 2013.

The species exists in very low abundances, usually within 6 feet of shorelines, throughout its known range. The general habitat requirements for the Carolina heelsplitter are shaded areas in large rivers to small streams, often burrowed into clay banks between the root systems of trees, or in runs along steep banks with moderate current. Recently, the Carolina heelsplitter has been found in sections of streams containing bedrock with perpendicular crevices filled with sand and gravel, and with wide riparian buffers. 12 Biological Analysis: A pedestrian foot survey conducted on April 18, 2018 revealed three perennial streams within the project limits. On-site streams are connected to downstream waters (Clarks Creek) via a pipe on Browne Rd., which does not provide a suitable connection to downstream waters that Carolina heelsplitter could utilize during its reproductive phase. Additionally, on-site streams are highly unstable with eroded stream banks and high sedimentation loads, which are not conducive to heelsplitter habitat. No heelsplitters were observed on-site during the site visit on April 18, 2018 (Photographs 3 and 4). Due to the break in biological connectivity to downstream waters and a lack of habitat, CWS concludes that this project will not affect the Carolina heelsplitter. Rusty Patched Bumble Bee (Bombus affinis) The Rusty patched bumble bee was listed as Endangered under the ESA in January 2017.13 Rusty patched bumble bees once occupied grasslands and tallgrass prairies of the Upper Midwest and Northeast, but most grasslands and prairies have been lost, degraded, or fragmented by conversion to other uses. According to USFWS guidance, "the rusty patched bumble bee is likely to be present in scattered locations that cover only about 0.1 % of the species' historical range. It is within these limited areas USFWS recommend that federal agencies and others consider the need to consult with the Service on the potential effects of their actions or the potential need for an incidental take permit under section 10(a)(1)(B). For the remaining 99.9% of the historical range, USFWS advise agencies and others that this bumble bee is not likely to be present and that consultations or incidental take coverage is not necessary. 04 According to USFWS' Rusty Patched Bumble Bee Interactive Map, Mecklenburg County is not within the 0.1 % historical range as no high potential zones or low potential zones are present within Mecklenburg County. Therefore, the proposed project will not affect the rusty -patched bumble bee. Northern long-eared bat (Myotis septentrionalis) The northern long-eared bat (NLEB) is one of the species of bats most impacted by the white -nose syndrome disease. Summer habitat (roosting habitat) of the NLEB includes forests and woodlots containing live trees and/or dead snags greater than three inches diameter at breast height with cavities or crevices. Winter habitat (hibernacula) of the NLEB includes caves, 12 NCDOT TE Animal Habitat Descriptions. 2015. https://connect.ncdot.gov/resources/Environmental/Compliance%20Guides%20and%20Procedures/TE%2OAnimal°/`2OHabitat% 20Descriptions%2OMar_6_2015.pdf s United States Fish and Wildlife Services. https://www.fws.gov/midwest/endangered/insects/rpbb/index.html 14 United States Fish and Wildlife Services. https://www.fws.gov/midwest/endangered/insects/rpbb/index.html Page 5 of 8 Cheyney Protected Species Assessment Report April 24, 2018 CWS Project No. 2018-0103 mines, rocky areas, or structures that mimic similar conditions such as culverts greater than 48 -inch in diameter.15 The NLEB was listed as Threatened (T) on April 2, 2015. The forested areas within the property are potential habitats for the NLEB. A Standard Local Operating Procedure for Endangered Species Act Compliance (SLOPES) was established for NLEB between the USFWS Asheville and Raleigh Ecological Offices and the United States Army Corps of Engineers (USACE), Wilmington District, on January 31, 2017.16 This SLOPES defines how the USACE will make determinations of effect to the NLEB on projects in which the USACE is the lead federal agency. Alternative Local Procedure 1 (ALP 1) applies for the Cheyney site as the action area is within range of the NLEB,17 the action area is located outside of a red 12 -digit HUC as defined by the Asheville Ecological Services Field Office,18 and consultation by the USACE is required on other listed species or critical habitat. The final 4(d) rule exempts incidental take of NLEB associated with activities that occur greater than 0.25 miles from a known hibernaculum site and greater than 150 feet from a known, occupied maternity roost from June 1 -July 31. In accordance with ALP 1 and the final 4(d) rule (effective as of February 16, 2016), any incidental take that may result from associated activities is exempt under the 4(d) rule. Therefore, this project is exempt under the 4(d) rule. Bald eagle (Haliaeetus leucocephalus) The Bald and Golden Eagle Protection Act,19 enacted in 1940, prohibits anyone, without a permit issued, from "taking" bald eagles, including their parts, nests, or eggs. Habitat for the bald eagle includes cliffs and forested areas typically within 1.0 mile of estuaries, large lakes, reservoirs, rivers, seacoast, and as they become more abundant, stands of undisturbed forest. A desktop -GIS assessment of the project study area, as well as the area within a 1 mile radius of the project limits, was performed on April 5, 2018 using 2017 color aerials. No water bodies large enough or sufficiently open to be considered potential feeding sources were identified. Since there was no foraging habitat within the review area, a survey of the project study area and the area within the project limits was not conducted. Additionally, a review of the NCNHP database on April 18, 2018 revealed no known occurrences of this species within 1.0 mile of the project study area. Due to the lack of habitat and known occurrences, CWS concludes that this project will not affect the bald eagle. Summary Based on the literature search and the results of the on-site assessment for suitable habitat of federally -protected endangered, and threatened species, suitable habitat was observed for the smooth coneflower. However, suitable habitat areas for the smooth coneflower are very poor quality with high degrees of non-native/invasive species competition, and there are active negative impacting activities to supporting habitat due to herbicide spraying from intensive farming on adjoining pasture areas. Suitable habitat was not observed within the project limits for smooth coneflower, Michaux's sumac, bald eagle, or Carolina heelsplitter.

CWS has concluded that activities within the project area will not directly or indirectly jeopardize the continued existence of Schweinitz's sunflower, the smooth coneflower, Michaux's sumac, bald eagle, rusty -patched bumble bee, and Carolina heelsplitter. Additionally, based on the project area location, no tree removal activities will occur within a 150 -foot radius of a known, occupied NLEB maternity roost from June 1 -July 31, and no trees will be removed within 0.25 miles of a known hibernaculum at any time of year. Therefore, any incidental take on NLEB that may result from associated activities is exempt under the 4(d) rule and notifications will follow the SLOPES agreement20.

All biological determinations of effect represent the best professional opinion of CWS and are not official determinations of effect. It is the responsibility of the lead federal agency to render an official determination of effect. Should the lead federal agency agree with CWS's initial findings of no effect, then no USFWS consultation is required to comply with Section 7 of the Endangered Species Act. Should the lead federal agency's determination of effect differ from the findings of CWS, formal or informal consultation with USFWS may be required.

Westinghouse Blvd. Charlotte, NC 28273 RE: Meridale Bolt On; CWS# 2018-0103 Dear Sean Martin: NCNHDE-5826 The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. A query of the NCNHP database indicates that there are records for rare species, important natural communities, natural areas, or conservation/managed areas within the proposed project boundary. These results are presented in the attached `Documented Occurrences' tables and map. The attached `Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists and is included for reference. Tables of natural areas and conservation/managed area within a one -mile radius of the project area, if any, are also included in this report. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. Also please note that the NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund (CWMTF) easement, or an occurrence of a Federally -listed species is documented near the project area. If you have questions regarding the information provided in this letter or need additional assistance, please contact Rodney A. Butler at rodney.butler(a)_ncdcr.gov or 919.707.8603.

This metric evaluates whether the wetland is well connected (Well) and/or loosely connected (Loosely) to the landscape patch, the contiguous naturally vegetated area and open water (if appropriate). Boundaries are formed by four -lane roads, regularly maintained utility line corridors the width of a four -lane road or wider, urban landscapes, maintained fields (pasture and agriculture), or open water > 300 feet wide. Well Loosely ❑A ❑A >: 500 acres ❑ B ❑ B From 100 to < 500 acres ❑ C ❑ C From 50 to < 100 acres ❑ D ❑ D From 10 to < 50 acres M E ❑ E < 10 acres ❑ F ❑ F Wetland type has a poor or no connection to other natural habitats 13b. Evaluate for marshes only. ❑Yes ❑ No Wetland type has a surface hydrology connection to open waters/stream or tidal wetlands. 14. Edge Effect - wetland type condition metric (skip for all marshes and Estuarine Woody Wetland) May involve a GIS effort with field adjustment. Estimate distance from wetland type boundary to artificial edges. Artificial edges include non -forested areas >- 40 feet wide such as fields, development, roads, regularly maintained utility line corridors, and clear -cuts. Consider the eight main points of the compass. Artificial edge occurs within 150 feet in how many directions? If the assessment area is clear cut, select option "C." MA 0 ❑ B 1 to 4 El 5to8 15. Vegetative Composition -assessment area condition metric (skip for all marshes and Pine Flat) El Vegetation is close to reference condition in species present and their proportions. Lower strata composed of appropriate species, with exotic plants absent or sparse within the assessment area. MB Vegetation is different from reference condition in species diversity or proportions, but still largely composed of native species characteristic of the wetland type. This may include communities of weedy native species that develop after clearcutting or clearing. It also includes communities with exotics present, but not dominant, over a large portion of the expected strata. El Vegetation severely altered from reference in composition, or expected species are unnaturally absent (planted stands of non - characteristic species or at least one stratum inappropriately composed of a single species), or exotic species are dominant in at least one stratum. 16. Vegetative Diversity -assessment area condition metric (evaluate for Non -tidal Freshwater Marsh only) ❑A Vegetation diversity is high and is composed primarily of native species (< 10% cover of exotics). ❑ B Vegetation diversity is low or has > 10% to 50% cover of exotics. ❑ C Vegetation is dominated by exotic species (> 50 % cover of exotics). 17. Vegetative Structure—assessmentarea/wetland type condition metric 17a. Is vegetation present? ®Yes ❑ No If Yes, continue to 17b. If No, skip to Metric 18. 17b. Evaluate percent coverage of assessment area vegetation for all marshes only. Skip to 17c for non -marsh wetlands. ❑A >_ 25% coverage of vegetation ❑ B < 25% coverage of vegetation 17c. Check a box in each column for each stratum. Evaluate this portion of the metric for non -marsh wetlands. Consider structure in airspace above the assessment area (AA) and the wetland type (WT) separately. AA WT a❑A ❑A Canopy closed, or nearly closed, with natural gaps associated with natural processes CO MB MB Canopy present, but opened more than natural gaps U ❑ C ❑ C Canopy sparse or absent o ❑A ❑A Dense mid-story/sapling layer I? EIB ❑ B Moderate density mid-story/sapling layer MC MC Mid-story/sapling layer sparse or absent El ❑A Dense shrub layer t EIB ❑ B Moderate density shrub layer 10 MC MC Shrub layer sparse or absent -o El ❑A Dense herb layer EIB ❑ B Moderate density herb layer MC MC Herb layer sparse or absent 18. Snags — wetland type condition metric (skip for all marshes) ❑A Large snags (more than one) are visible (> 12 inches DBH, or large relative to species present and landscape stability). M B Not A 19. Diameter Class Distribution —wetland type condition metric (skip for all marshes) MA Majority of canopy trees have stems > 6 inches in diameter at breast height (DBH); many large trees (> 12 inches DBH) are present. ❑ B Majority of canopy trees have stems between 6 and 12 inches DBH, few are > 12 inch DBH. ❑ C Majority of canopy trees are < 6 inches DBH or no trees. 20. Large Woody Debris — wetland type condition metric (skip for all marshes) Include both natural debris and man -placed natural debris. ❑A Large logs (more than one) are visible (> 12 inches in diameter, or large relative to species present and landscape stability). M B Not A 21. Vegetation/Open Water Dispersion — wetlandtype/open water condition metric (evaluate for Non -Tidal Freshwater Marsh only) Select the figure that best describes the amount of interspersion between vegetation and open water in the growing season. Patterned areas indicate vegetated areas, while solid white areas indicate open water. ❑A El El El ] t-�1 22. Hydrologic Connectivity—assessment area condition metric (evaluate for riparian wetlands and Salt/Brackish Marsh only) Examples of activities that may severely alter hydrologic connectivity include intensive ditching, fill, sedimentation, channelization, diversion, man-made berms, beaver dams, and stream incision. Documentation required if evaluated as B, C, or D. ❑A Overbank and overland flow are not severely altered in the assessment area. ❑B Overbank flow is severely altered in the assessment area. [RC Overland flow is severely altered in the assessment area. ❑ D Both overbank and overland flow are severely altered in the assessment area. Notes Exotic species such as Chinese privet and Japanese honeysuckle present, but not dominant within the wetland. Some vehicle tracts are present, but not over majority of assessment area. The area receives eccessive stormwater runoff from the development upstream.
