In March 2021, Wildlands completed construction of the initial Wyant Lands Mitigation Site (Site)which involved the restoration and enhancement of approximately 7,540 linear feet (LF) of Wyant Creek and three unnamed tributaries (UT1—UT3), as well as the re-establishment and rehabilitation of approximately 14.2 acres of wetlands. Restoration of these streams and adjacent wetlands was proposed to provide 6,863.7 stream credits and 13.1 wetland credits within the approved mitigation plan dated April 2020. A contract addendum and revised mitigation approach was proposed by Wildlands and was approved by DMS in July 2021.The addendum proposes to restore approximately 396 LF of UT2 Reach 1 which was proposed as stream enhancement II within the approved mitigation plan.Additionally, the addendum proposes to restore and create an additional 5.742 acres of wetland features at the Site.This mitigation plan addendum is proposing an additional 231.600 SMUs and 4.513 WMUs based on the proposed work at the Site. Upon addendum approval by the North Carolina Interagency Review Team (IRT),total project assets for the Site will increase to 7,090.667 SMUs and 17.608 WMUs for the entire project.

Restoration of these streams and adjacent wetlands area were approved to provide 6,863.7 stream credits and 13.1 wetland credits within the Catawba basin in the original mitigation plan.The original Site is protected by a 41.5-acre conservation easement.The proposed mitigation addendum area will include an additional 5.9-acre conservation easement which will abut the existing recorded conservation easement north of the previously restored wetland area (Figure 2A).The amended project area will provide an additional 5.741 acres of wetland re-establishment, rehabilitation, and creation. In addition to the expanded wetland area,this addendum proposes a revision of mitigation approach along UT2 Reach 1 from enhancement II to restoration. Work as part of this mitigation addendum is proposed to provide an additional 231.600 stream credits and 4.513 wetland credits. Project information for the proposed addendum is shown in Table 1. Table 1: Project Attribute Table Part 1 Amended Project Information Project Name Wyant Lands Mitigation Site County Lincoln Project Area(acres) 41.5 (original); 6.0(addendum);47.5 (total) Project Coordinates(latitude and longitude) 35°32'2.13"N 81° 18'52.82"W Planted Acreage(acres of woody stems planted) 37.8(original); 7.2(addendum);45.0(total) L.0 Addendum Area Baseline and Existing Conditions 2.1 Project Description Construction and planting of the approved mitigation Site assets were completed in spring of 2021 and the as-built and baseline monitoring report was submitted to DMS in October 2021.This mitigation plan addendum includes additional conservation easement area to include additional wetlands in the pasture area north of the original wetland restoration area.Wetlands will be restored and created by removing the crowned field material, removing side cast berms in the agricultural pasture and filling existing ditches within the proposed wetland areas. Additionally, UT2 Reach 1 is proposed for restoration with an appropriate pattern, profile, and dimension. A best management practice (BMP)will be installed along the reach to stabilize a recently developed water quality stressor from the adjacent agricultural pasture. A new conservation easement containing the amended wetland area that abuts the original recorded conservation easement will be acquired as part of the project addendum. UT2 Reach 1 is currently within the existing recorded conservation easement and no additional easement will be required based on the revised stream mitigation approach. 2.2 Addendum Existing Conditions-Wetlands 2.2.1 Addendum Area Jurisdictional Wetlands Wildlands previously delineated wetland waters of the United States within the original project areas and a Preliminary Jurisdictional Determination (PJD) was issued in August 2019.The issued PJD and associated NCDWR Stream Classification Forms and USACE Wetland Determination Data Sheets were Wyant Lands Mitigation Addendum Page 3 DMS ID No. 100595 included in Appendix 3 of the approved mitigation plan. An addendum to the existing PJD was submitted in August 2021 and included additional assessment area based on this proposed project expansion. Wildlands received approval of the amended PJD on September 15th, 2021.The amended PJD submittal and associated approval is included in Appendix 3A of this mitigation plan addendum.The amended PJD includes an additional four jurisdictional wetland features (Q-T) and one additional open water feature (Open Water 2) documented within the expanded wetland assessment area which can be seen in Figure 6.1A. On-site wetland features exhibit prolonged saturation within the upper 12 inches of the soil profile, hydrophytic vegetation, and a depleted matrix or darkened surface horizons. Common vegetation species present in wetlands include creeping buttercup (Ranunculus repens), marsh dewflower(Murdannia keisak), and soft rush (Juncus effuses). Wetlands L, M, and N are associated with UT1 Reach 1 and discussed in the original mitigation plan. Existing wetlands delineated as part of the project expansion were evaluated using the North Carolina Wetland Assessment Method (NCWAM)to generate function ratings for specific wetland types. Using the NCWAM dichotomous key and best professional judgement, existing wetlands in the addendum area were classified based on the reference wetland type as if the area was not disturbed;therefore, wetlands were classified as bottomland hardwood forests.The NCWAM ratings of wetlands in the addendum area is low.The wetlands scored as low functioning systems when compared to reference conditions as a result of impairments to all three of the primary functions (hydrology, water quality, and habitat). Hydrology and water quality functions generally received low scores due to ditching and berms that reduce surface and subsurface water storage and limit hydrologic connectivity with streams. Habitat quality received low scores due to vegetation composition and structure; most on-site wetlands are poorly connected to adjacent natural habitats and are actively managed for grazing. NCWAM field assessment forms and the rating calculator outputs for additional jurisdictional wetlands within the expanded project area are included in Appendix 4A.Table 2 below outlines the additional jurisdictional wetlands and open water features identified within the proposed project expansion.

During the initial project evaluation, UT2 was determined to be a perennial stream with a total score of 38. No major watershed or hydrologic changes have occurred upstream of the project, so no update was required to the jurisdictional status of UT2. No additional stream resources are included as part of this mitigation plan addendum.The current condition of UT2 Reach 1 is described in detail below.Table 3 provides a summary of the existing stream condition.The existing condition alignment and cross-section data collection locations are illustrated in Figure 6.2A. 2.3.1 UT2 Reach 1 - gt s� �UT2 Reach 1 is located downstream from an existing farm pond.The farm pond was fenced for cattle exclusion as part of the original project. UT2 Reach 1 flows through a , " •„,r4 . z Y moderately sloped and moderately confined alluvial valley until intersecting with an adjacent parcel owned by4tt ::. Rutherford Electric Membership Cooperation (REMCO).The 4 reach was previously in active cattle pasture with evidence - of cattle activityincludingfeces and trampling, as well as • h 3_.;, some cattle runs and wallow areas. When the stream was Eroding Outside Bend Along UT2 Reach 1 initially evaluated in October 2017, the primary stream stressors were invasive vegetation and cattle activity.An assessment of the stream conducted in April 2019 indicated the stream had a moderately stable dimension, moderate bedform diversity, and existing riffle-pool habitat. However, during the period from April 2019 and August 2021, the Site received multiple large rain events, and this reach degraded rapidly. Runoff from an upgradient field initiated a large headcut in the right floodplain which deposited sediment within the stream channel and impacted bedform. Invasive vegetation stems increased within the floodplain and are outcompeting native vegetation. Fine sediment loads increased from active bank erosion and the adjacent floodplain headcut.

An updated floodplain development permit application will be submitted to the local floodplain administrator. 3. See approved mitigation plan 3.1 Biological and Cultural Resources A Categorical Exclusion for the Wyant Lands Mitigation Site was approved by the Federal Highway Administration (FHWA) on October 19, 2018.This document included investigation into the presence of threatened and endangered species on Site protected under The Endangered Species Act of 1973, as well as any historical resources protected under The National Historic Preservation Act of 1966.The conclusion for cultural resources per the Categorical Exclusion research and response by the State Historic Preservation Office is that there are no historic resources that would be affected by this project. The signed Categorical Exclusion checklist is found in Appendix 5 of the approved mitigation plan. 3.2 Addendum FEMA Floodplain Compliance and Hydrologic Trespass A Lincoln County floodplain development permit was obtained for the original portions of the Wyant Lands Mitigation Site in November 2019 in compliance with FEMA floodplain and Lincoln County ordinances. Work in the addendum area also occurs in the Special Flood Hazard Area (Zone AE) of Pott Creek mapped on Lincoln County Flood Insurance Rate Map Panel 3604.An amended floodplain development permit has been requested and a revised hydraulic modeling study has been developed that includes the addendum area grading. The proposed design associated with the addendum area has limited risk of potential hydrologic trespass.The addendum wetland area is graded to provide positive drainage toward the recorded conservation easement. UT2 Reach 1 has sufficient gradient that the design will not result in backwater effects upstream of the work area. 3.3 Addendum 401/404 Wildlands incorporated existing stream and wetland stability and/or function into design approaches for avoidance and minimization measures. Wetlands within the amended conservation easement or limits of disturbance will be denoted in the final construction plans including the Erosion and Sediment Control sheets. Proposed protection including safety fencing of these areas where possible will be shown in the Detail plan sheets as well as specified within the project manual. Floodplain grading will result in temporary impacts to most existing wetlands while channel realignment and filling open waters will result in permanent impacts. Wildlands expects a net gain of wetland area and function as a result of floodplain grading and filling existing open waters.Table 6 estimates the anticipated impacts to wetlands and open waters.The Pre-Construction Notification, including these data, will be provided with the final addendum mitigation plan.

Wetland function will be improved at the Site via a reduction in surface drainage features resulting in hydrologic uplift.The project goals and related objectives and outcomes are described in Table 7. Project goals are desired project outcomes and are verifiable through measurement and/or visual assessment. Objectives are activities that will result in the accomplishment of goals.The project will be monitored after construction to evaluate performance as described in Section 6.0 of this report.

Key morphological parameters for the UT2 Reach 1 are listed in Table 8. UT2 Reach 1 is proposed for stream restoration and will be constructed as a Priority 1 restoration.The Priority 1 approach will raise the stream bed so that the bank full elevation will concede with the existing floodplain.The cross-section will be constructed to convey the design discharge. UT2 Reach 1 is designed as a Rosgen Bc-type channel that will meander within the existing narrow valley.The reach is actively eroding from bank erosion and a floodplain headcut. Bank grading,the installation of in-stream structures,that of invasive species, and planting to the existing riparian buffer will be performed as part of the proposed restoration.

' are within the broad floodplain of Pott Creek and are currently managed as agricultural pasture used for cattle grazing and/or hay production. Wildlands evaluated existing conditions within the proposed wetland areas to understand existing and potential hydric soils, current surface drainage features, existing vegetation, and the potential for increases in hydrology based on the proposed Site design. Proposed wetland areas are currently ditched with three swales and two main perimeter ditches.The fields are currently in pasture grasses and cattle grazing is the intended future use of the fields if they are not added to the mitigation project. Figure 10.1A shows approximate areas of proposed wetland approach including creation, rehabilitation, and re-establishment. Areas proposed for wetland re- habilitation are currently jurisdictional areas which are impaired by agricultural manipulation and drainage. Areas of wetland re-establishment have been floodplain riparian wetlands prior to agricultural manipulation and the installation of drainage features. Similarly, areas of wetland creation are also believed to have been floodplain riparian wetlands prior to agricultural manipulation, however drainage features and field crowning has resulted in deep strata of overburden (typically greater than or equal to 12")which will be removed as part of the wetland development. Based on the depth of grading these areas and lack of current or relic hydric indicators,these areas are propose wetland creation. Soils within the northern fields are mapped as Chewacla loam.The soils within this area were evaluated by Wildland personnel in March 2021. Eleven soil borings were taken throughout the proposed wetland mitigation area and soils were evaluated for hydric indicators as well as potential hydric development. Generally, soils within low, wet swales have developed current hydric indicators including low chromas and redox concentrations occurring as pore linings within the top 10" of the soil surface. Soils outside of low, wet swales, and particularly within crowned areas, exhibited higher chroma within the first 12" with lower chroma and/or reduced soil features beyond depths of 12". Results from Wildlands' soils investigation are included in Appendix 6A. The approach within the amended wetland mitigation area will be to remove the current overburden from the crowned fields and fill the existing drainage features to restore a natural wetland hydrologic regime. Pasture grasses will be graded or treated for removal, and the area will be roughened to retain surface water and increase retention times.A conservation easement will be recorded and will connect to the existing conservation easement, expanding the floodplain riparian area being protected in perpetuity.The wetland restoration area will be planted in woody vegetation consistent with a bottomland hardwood forested wetland system. Fencing will be installed around the additional conservation easement or cattle will be removed from the easement to prevent any future cattle access. 5.3 Addendum Existing Hydrology Four groundwater monitoring gauges were installed in the amended wetland area on June 23, 2021 (Appendix 6A).The location of the existing groundwater gauges is shown in Figure 6.1A.The four groundwater gauges were placed in transects to evaluate the groundwater elevations across the existing Wyant Lands Mitigation Addendum Page 10 DMS ID No. 100595 agricultural area proposed for wetland crediting. Growing season dates were defined as March 27 to November 6 (224 days) by the Lincolnton 4W North Carolina WETS table for 50%probability of soil temperatures greater than 28 degrees Fahrenheit. Groundwater gauge 102 malfunctioned and did not collect data during the June 23 to September 15 period. The data collected from the remaining three groundwater gauges suggest the wetland areas are drained by the existing ditch networks.The groundwater levels quickly increase during rain events and rapidly recede after rain events.The gauges continue to slowly receding overtime until the next rain event.The average percent consecutive days above 12-inches of soil saturated was 2%for Ground water gage 101, 103, and 104 the three addendum groundwater gauges located within the proposed re- establishment area. Gauge data supports the design approach of filling existing ditches to raise hydrology within the addendum wetland area. 5.4 Proposed Best Management Practices(BMPs) In addition to the proposed stream design outlined in Section 4.1, one BMP is proposed in the right floodplain of UT2 Reach 1 as shown in Figure 10.2A.The proposed BMP will be designed as a step-pool stormwater conveyance (SPSC) consisting of short riffles, rock steps, and pools designed to stabilize the existing headcut.The BMP is intended to address adjacent water quality stressors and reduce sediment inputs from adjacent agricultural practices. Maintenance is not anticipated for the proposed BMP. A basic detail is shown in Sheet 5.6 of the design plans included in Appendix 8A. Specific design dimensions will be finalized prior to project construction. 5.5 Addendum Vegetation and Planting Plan The riparian buffer and most wetland areas will be planted with bare root seedlings. Species chosen to be planted within wetland areas were selected based on community types as well as their ability to handle wetter ground conditions based on standing water and high groundwater levels observed in wetland areas at the Site. The stream banks will be planted with live stakes and the channel toe will be planted with multiple herbaceous species. Permanent herbaceous seed will be spread on streambanks, floodplain areas,and disturbed areas within the project easement. Bare root seedlings and live stakes will be planted in the dormant season between November 15 and March 15. Figure 10A illustrates the proposed planting zones throughout the site. Species chosen for the planting plan are listed on Table 9 below and on sheet 4.0 of the preliminary plans located in appendix A.

Annual monitoring data will be reported using the DMS Annual Monitoring Reporting Template (April 2015).The monitoring report shall provide project data chronology that will facilitate an understanding of project status and trends, ease population of DMS databases for analysis and research purposes and assist in close-out decision making. Using the DMS As-Built Baseline Monitoring Report Template (June 2017), a baseline monitoring document and as-built record drawings of the project will be developed within 60 days of the planting completion and monitoring installation on the restored Site. Monitoring reports will be prepared in the fall of each monitoring year and submitted to DMS by November 30.These reports will be based on the DMS Annual Monitoring Template (April 2015) and Closeout Report Template (June 2017). Full monitoring reports will be submitted to DMS in monitoring years 1, 2, 3, 5, and 7. Abbreviated monitoring reports will be submitted in monitoring years 4 and 6. Closeout monitoring period will be seven years beyond completion of construction or until performance standards have been met. 7.1 Addendum Monitoring Components Project monitoring components are listed in more detail in Table 11.

Quad: Reepsville NOTIFICATION OF JURISDICTIONAL DETERMINATION Property Owner/Applicant: Wildlands Engineering,Inc./Attn.: Ian Eckardt Address: 1430 S.Mint Street,Suite 104 Charlotte,NC 28203 Telephone Number: 704-332-7754 Email: ieckardt@wildlandseng.com Size(acres): 10.2 Nearest Town: Vale Nearest Waterway: Pott Creek and UTs Pott Creek Coordinates: 35.53072,-81.31928 River Basin/HUC: South Fork Catawba(03050102) Location description: The project site is located on a tract of land(PIN 3615-07-4254)at 2847 Wyant Road in Vale, Lincoln County,North Carolina. Indicate Which of the Following Apply: A. Preliminary Determination X There are waters,including wetlands,on the above described project area, that may be subject to Section 404 of the Clean Water Act(CWA)(33 USC § 1344)and/or Section 10 of the Rivers and Harbors Act(RHA)(33 USC § 403). The waters,including wetlands, have been delineated, and the delineation has been verified by the Corps to be sufficiently accurate and reliable. Therefore this preliminary jurisdiction deteunination may be used in the peunit evaluation process,including deteunining compensatory mitigation. For purposes of computation of impacts,compensatory mitigation requirements, and other resource protection measures, a peunit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be affected in any way by the peu,uitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary deteunination is not an appealable action under the Regulatory Program Administrative Appeal Process(Reference 33 CFR Part 331). However,you may request an approved JD, which is an appealable action,by contacting the Corps district for further instruction. _ There are wetlands on the above described property, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act(RHA)(33 USC § 403).However, since the waters,including wetlands, have not been properly delineated,this preliminary jurisdiction deteunination may not be used in the peunit evaluation process. Without a verified wetland delineation,this preliminary deteunination is merely an effective presumption of CWA/RHA jurisdiction over all of the waters,including wetlands, at the project area, which is not sufficiently accurate and reliable to support an enforceable peunit decision. We recommend that you have the waters of the U.S. on your property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner,you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. B. Approved Determination _ There are Navigable Waters of the United States within the above described property subject to the peunit requirements of Section 10 of the Rivers and Harbors Act(RHA) (33 USC § 403) and Section 404 of the Clean Water Act(CWA)(33 USC § 1344). Unless there is a change in law or our published regulations,this deteunination may be relied upon for a period not to exceed five years from the date of this notification. _ There are waters of the U.S.,including wetlands, on the above described project area subject to the permit requirements of Section 404 of the Clean Water Act(CWA) (33 USC § 1344). Unless there is a change in the law or our published regulations,this deteunination may be relied upon for a period not to exceed five years from the date of this notification. _ We recommend you have the waters of the U.S. on your property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner,you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. _ The waters of the U.S.,including wetlands, on your project area have been delineated and the delineation has been verified by the Corps. We strongly suggest you have this delineation surveyed. Upon completion,this survey should be reviewed and verified by the Corps. Once verified,this survey will provide an accurate depiction of all areas subject to CWA jurisdiction on your property which,provided there is no change in the law or our published regulations,may be relied upon for a period not to exceed five years. _ The waters of the U.S.,including wetlands, have been delineated and surveyed and are accurately depicted on the plat signed by the Corps Regulatory Official identified below on . Unless there is a change in the law or our published regulations,this deteunination may be relied upon for a period not to exceed five years from the date of this notification. _ There are no waters of the U.S.,to include wetlands,present on the above described project area which are subject to the peunit requirements of Section 404 of the Clean Water Act(33 USC 1344). Unless there is a change in the law or our published regulations,this deteunination may be relied upon for a period not to exceed five years from the date of this notification. _ The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act (CAMA). You should contact the Division of Coastal Management in Morehead City,NC, at(252)808-2808 to deteunine their requirements. Placement of dredged or fill material within waters of the US,including wetlands,without a Department of the Auny permit may constitute a violation of Section 301 of the Clean Water Act(33 USC § 1311). Placement of dredged or fill material, construction or placement of structures,or work within navigable waters of the United States without a Department of the Auny permit may constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act(33 USC § 401 and/or 403). If you have any questions regarding this deteunination and/or the Corps regulatory program,please contact David Brown at 828-271-7980, ext.4232 or david.w.brown@usace.army.mil. C. Basis for Determination: See attached preliminary jurisdictional deteunination four. D. Remarks: The potential waters of the U.S. at this site were verified by the Corps during a site inspection on September 9,2021, and are as approximately depicted on the attached Delineation Map,Figures 3.0 and 3.4 submitted by Wildlands Engineering,Inc. This project area covers an additional 10.2 acres that is being added to the existing NCDMS Wyant Lands Mitigation Site project area. E. Attention USDA Program Participants The delineation included herein has been conducted to identify the location and extent of the aquatic resource boundaries and/or the jurisdictional status of aquatic resources for purposes of the Clean Water Act for the particular site identified in this request. This delineation and/or jurisdictional deteunination may not be valid for the Wetland Conservation Provisions of the Food Security Act of 1985, as amended. If you or your tenant are USDA program participants,or anticipate participation in USDA programs,you should discuss the applicability of a certified wetland deteunination with the local USDA service center,prior to starting work.

The Corps of Engineers believes that there may be jurisdictional aquatic resources in the review area, and the requestor of this PJD is hereby advised of his or her option to request and obtain an approved JD (AJD)for that review area based on an informed decision after having discussed the various types of JDs and their characteristics and circumstances when they may be appropriate. 6 2. In any circumstance where a permit applicant obtains an individual permit, or a Nationwide General Permit (NWP) or other general peunit verification requiring "pre-construction notification" (PCN), or requests verification for a non-reporting NWP or other general permit, and the permit applicant has not requested an AJD for the activity, the permit applicant is hereby made aware that: (1)the permit applicant has elected to seek a permit authorization based on a PJD,which does not make an official determination of jurisdictional aquatic resources; (2)the applicant has the option to request an AJD before accepting the terms and conditions of the permit authorization, and that basing a permit authorization on an AJD could possibly result in less compensatory mitigation being required or different special conditions; (3)the applicant has the right to request an individual permit rather than accepting the terms and conditions of the NWP or other general permit authorization; (4) the applicant can accept a permit authorization and thereby agree to comply with all the terms and conditions of that permit, including whatever mitigation requirements the Corps has determined to be necessary; (5) undertaking any activity in reliance upon the subject permit authorization without requesting an AJD constitutes the applicant's acceptance of the use of the PJD; (6) accepting a peunit authorization (e.g., signing a proffered individual permit) or undertaking any activity in reliance on any form of Corps permit authorization based on a PJD constitutes agreement that all aquatic resources in the review area affected in any way by that activity will be treated as jurisdictional, and waives any challenge to such jurisdiction in any administrative or judicial compliance or enforcement action, or in any administrative appeal or in any Federal court; and (7)whether the applicant elects to use either an AJD or a PJD,the JD will be processed as soon as practicable. Further, an AJD, a proffered individual permit (and all terms and conditions contained therein), or individual permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331. If,during an administrative appeal, it becomes appropriate to make an official determination whether geographic jurisdiction exists over aquatic resources in the review area, or to provide an official delineation of jurisdictional aquatic resources in the review area, the Corps will provide an AJD to accomplish that result, as soon as is practicable. This PJD finds that there "may be"waters of the U.S. and/or that there "may be"navigable waters of the U.S. on the subject review area, and identifies all aquatic features in the review area that could be affected by the proposed activity, based on the following information: SUPPORTING DATA Data reviewed for preliminary JD (check all that apply) - Checked items should be included in subject file.

There are a number of field ditches that dissect the site. Most of the area evaluated is currently planted in soybeans but some of the area is in pasture. METHODOLOGY On November 13th, 2017 Kevin Martin (LSS, PWS) of S&EC, PA performed a soil evaluation at the site. Hand auger borings were advanced on the property at locations as appropriate to approximately estimate the location and extent of hydric soils within the project area (see attached Approximate Hydric Soil Locations Map). Each soil boring was evaluated to assess the presence or absence of hydric soil indicators. Hydric soil indicators were identified utilizing the NRCS Field Indicators of Hydric Soils in the Unities States-A Guide for Identifying and Delineating Hydric Soils (Version 7.0, 2010). All areas evaluated are mapped as the Chewacla soil series (Fine-loamy, mixed, active, thermic Fluvaquentic Dystrudepts) by NRCS. Most hydric soils observed onsite were fine loamy or clayey and are most like the Wehadkee (Fine-loamy, mixed, active, nonacid, thermic Fluvaquentic Endoaquepts) soil series. RESULTS Numerous soil borings were performed within the study area. Soil characteristics were evaluated and all areas identified as containing hydric soils met the hydric soil criteria described below. An X" on the map indicates soil boring location and depth to hydric soil indicators, except in H2 area where the " indicate thickness of the depleted layer from the surface downward. U-are non hydric soil areas H- are hydric soils areas containing a depleted matrix. C- are buried hydric soils due to "crowning' of the fields. Crowned material ranges from 12" to 18" thick in most areas. A depleted matrix is present beneath the material used to crown the field. H2- areas have hydric soil indicators (a depleted matrix) but only in the top 2 to 4" of the soil profile. This area may have been a natural depression in the floodplain or may have been created over time by manipulation of the area and by ponding caused in part by a man made levee adjacent to a ditch. Indicator F3: Depleted Matrix Technical Description: A layer that has a depleted matrix with 60 percent or more chroma of 2 or less and that has a minimum thickness of either: (a) 2 in. (5 cm) if the 2 in. (5 cm) is entirely within the upper 6 in. (15 cm) of the soil, or 2 (b) 6 in. (15 cm) starting within 10 in. (25 cm) of the soil surface, Wetland Hydrology Indicators: While all of the borings performed within areas identified as hydric soils on the attached map exhibited hydric soil indicators, many areas containing hydric soils did not exhibit Primary Wetland Hydrology or Secondary Wetland Hydrology Indicators. Except that part of the evaluation area was flooded at the time of the evaluation. 3 --Kw ► ,»,•,..-i /7 / - Project Location y Proposed Conservation Easement(37.8 Acres) \\ Temporary Construction Easement _ _ Topographic Contour 5' � '` k Existing Ditch7 I, 30 + t I n Soils Investigation I 1 ®0„ I ' 1 - C-Buried Hydric(2.9 Acres) I ®15 F i; I i ■ H-Hydric(8.6 Acres) , :: f ii U-Not Hydic(1.7 Acres) 0911 lc\� it ' H2-Shallow Hydric(1.5 Acres) ®1 0�� ®$„ '\ \ \\.\\ ® Soil Study Borings �ti , t fit• Y a t VII\I) [II, ro ®4„ 012" ! t .� - � ®On gin. _. ®16" ' ®2" � I --"--) I .P �� 1 i SiillN\:\:...\ii i- ,, ®16" i ,\ -i: I. / .AV, . .. • _ (1 , \i,;1111 . -, :- v4tc t. t . i.. 4i. lir �1 _ ter .. r r�. e'er,, .�ir �; ,0 a• la �~ r \ . g WYANT CREEK REACH 4 _ _ , ®4" . - , • ..11,41„-‘ , ... \ -'+ \-\\\-k ®2" \.

METHODOLOGY On February 7th, 2019 Kevin Martin (LSS, PWS) of S&EC, PA performed a soil evaluation at the site. Eighty five hand auger borings were advanced on the property at locations as appropriate to approximately estimate the location and extent of hydric soils within the project area(see attached Soil Study Exhibit). Each soil boring was evaluated to assess the presence or absence of hydric soil indicators.
