WLS proposes to develop this private commercial mitigation site in the Yadkin River Basin, 8-digit Hydrologic Unit Code (HUC) 03040101. The Miller project is the fourth site in the WLS Yadkin 01 Umbrella Bank. The purpose of the Bank is to provide stream and wetland mitigation credits to compensate for unavoidable impacts to Waters of the U.S. authorized under sections 401 and 404 of the Clean Water Act, Section 10 of the Rivers and Harbors Act, and all applicable state statutes. 1.2 Bank Site Location The Project (36.317593, -80.494101) is located in Surry County, in the Pinnacle Community (Figure 1). The Project is located in the 12-digit HUC 030401011006 within the Yadkin River Basin. The project reaches include unnamed tributaries to Grassy Creek. Grassy Creek flows south to its confluence with the Yadkin River approximately three miles downstream. To access the Project from Winston-Salem, NC, follow US Highway 52 north for approximately 19 miles. Take exit 129 for Perch Road towards Pinnacle. Continue on Perch Road for 1.0 mile and turn right onto Mt. Zion Road. Continue for 2.2 miles and then turn left onto Pinnacle Hotel Road. Continue for approximately 1.2 miles to the site access off Pinnacle Hotel Road. 1.3 Mitigation Goals and Objectives The purpose of the proposed bank is to generate compensatory mitigation credits in the Yadkin River Basin (HUC 03040101). The mitigation goals and objectives will be based on the current resource condition and functional uplift capacity of the project site watershed to improve and protect aquatic resources comparable to stable stream systems within the Piedmont Physiographic Province. The proposed bank will address the general watershed goals and restoration opportunities outlined in the North Carolina Division of Mitigation Services (DMS) Upper Yadkin River Basin Restoration Priorities Plan (RBRP, 2009). The project goals include the following components: 1. Reducing sediment, soil erosion, turbidity, and nutrient inputs such as fecal coliform bacteria, nitrogen, and phosphorus to the Upper Yadkin River Watershed. 2. Restoring, enhancing, preserving and protecting streams, wetlands, riparian buffers and aquatic habitat functions. 3. Improving riparian corridors and targeting restoration of impacted streams and riparian buffer areas. 4. Implementing agricultural BMPs and water quality features such as livestock exclusion fencing, alternative watering structures, nutrient management, and stormwater wetlands. WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Water & Land Solutions Page 5 To accomplish these goals, the following objectives will be measured to document overall project success: • Provide a floodplain connection to the incised Project stream reaches by lowering bank height ratios (BHRs) to less than 1.2, thereby promoting more natural floodplain storage and overbank flood flows. • Improve bedform diversity by increasing scour pool to pool spacing and depth variability and livestock exclusion. • Increase native species riparian buffer vegetation density/composition along streambank and floodplain areas that meet requirements of a minimum 50 -foot-wide and 210 stems/acre after the monitoring period. • Improve aquatic habitat and fish species diversity and migration through the addition of in-stream cover and native woody debris. • Site protection through a 14-acre conservation easement that will exclude livestock and protect all streams, wetlands, riparian buffers, and aquatic resources in perpetuity. 1.4 Watershed Need and Technical Feasibility As a result of implementing this Project, WLS will restore, enhance, and protect approximately 4,963 linear feet of stream to address components as defined in the RBRP. In order to appropriately offset unavoidable impacts to Waters of the United States associated with growth and development, the proposed Project is critical to improving water quality and protecting aquatic resource functions in this region. The technical feasibility of the Project is assured due to WLS’ extensive experience with stream and wetland mitigation in North Carolina and throughout the Southeast. Examples of WLS’ success with stream and wetland restoration include the WLS Neuse 01 Umbrella Mitigation Bank and the WLS Yadkin 01 Umbrella Mitigation Bank. The absence of fatal flaws, such as hydrologic trespass and threatened and endangered species, means the Project is unlikely to be impeded by resource issues, or by objections from landowners. 2 Qualifications 2.1 Bank Sponsor This instrument modification is submitted on behalf of Water & Land Solutions, LLC (Sponsor), who will serve as the Sponsor for the Miller Mitigation Bank, a site in WLS Yadkin 01 Umbrella Mitigation Bank.

WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Water & Land Solutions Page 7 Toms Creek Tributaries Mitigation Project, Surry County, NC WLS has developed a private commercial mitigation bank as part of the WLS Yadkin 01 Umbrella Mitigation Bank located in the Yadkin River Basin, 8-digit HUC 03040101. The Toms Creek Tributaries Mitigation Project is located five miles north of the Town of Pilot Mountain, NC. The Project site is located in the APM LWP subwatershed ‘TC-3’ and the unnamed tributaries drain to Toms Creek, which is listed as a water supply watershed (WS-II) for Pilot Mountain and High-Quality Waters (HQW), according to the NC Division of Water Resources. These waters are also protected for Class ‘C’ uses per the North Carolina Division of Water Resources. The project will restore, enhance, preserve and protect over 6,552 linear feet of critical headwater streams that was historically in agricultural use. In addition, this project will restore/enhance approximately 2.93 acres of riparian wetlands. 3 Bank Establishment and Operation The WLS Yadkin 01 Umbrella Bank has been developed as a private commercial mitigation bank under an umbrella mitigation banking instrument (UMBI) in the Yadkin River Basin, 8-digit HUC 03040101. The compensatory mitigation credits developed under the UMBI will be available to public, private, and non- profit customers. The proposed bank site will include a combination of Stream Restoration, Enhancement, and Preservation activities, depending upon the need of the individual reach. The proposed mitigation types, credit ratios, and performance monitoring will follow current USACE guidance documents as approved by the USACE District Engineer (DE) and IRT. 3.1 Site Ownership The Sponsor will record a conservation easement in the county Register of Deeds for the site upon IRT bank approval. WLS has provided Agent Authorization forms in Appendix C. The current property owners for the proposed site are listed in Table 1. Table 1.

Use of approved mitigation credits from the Bank to WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Page 8 compensate for impacts outside the GSA may be considered by USACE on a case-by-case basis. The Site will provide compensatory mitigation for warm water stream impacts. 3.3 Credit Release Schedule All credit releases will be based on the total number of mitigation credits generated as reported in the approved final mitigation plan and verified by the as-built survey. The initial credit release will be based on the proposed restoration lengths (SMCs) as approved in the final mitigation plan. The credit ledger will be managed by WLS and approved by the USACE District Engineer (DE) and IRT. The estimated credits will be released following current USACE guidance, as shown in Table 2. Table 2. Credit Release Schedule Credit Milestone Release Activity Stream: Interim Release Stream: Total Released 1 Site Establishment and preservation credits (as defined in Section 3.3.1) 15% 15% 2 Completion of all initial physical and biological improvements made pursuant to the Mitigation Plan 15% 30% 3 Year 1 Monitoring Report demonstrates that channels are stable and interim performance standards have been met 10% 40% 4 Year 2 Monitoring Report demonstrates that channels are stable and interim performance standards have been met 10% 50% 5 Year 3 Monitoring Report demonstrates that channels are stable and interim performance standards have been met 10% 60% 6 Year 4 Monitoring Report demonstrates that channels are stable and interim performance standards have been met 5% 65% (75%*) 7 Year 5 Monitoring Report demonstrates that channels are stable and interim performance standards have been met 10% 75% (85%*) 8 Year 6 Monitoring Report demonstrates that channels are stable and interim performance standards have been met 5% 80% (90%*) 9 Year 7 Monitoring Report demonstrates that channels are stable and interim performance standards have been met 10% 90% (100%*) Note: *10% reserve of credits to be held back until the bankfull event performance standard has been met. 3.3.1 Initial Allocation of Released Credits The standard credit release schedule generated through stream mitigation projects will occur upon establishment of the bank site, and upon initial satisfactory completion of the following activities: 1) Execution and Approval of the UMBI by the Sponsor and the USACE 2) Approval of the Final Mitigation Plan 3) Confirmation the mitigation bank site has been secured 4) Delivery of the financial assurances 5) Recordation of the long-term protection mechanism and title opinion acceptable to the USACE 6) Issuance of the 404-permit verification for construction of the site, if required. For preservation credits, 100% of the preservation credits will be released with the completion of Task 1 above. WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Water & Land Solutions Page 9 3.3.2 Subsequent Credit Releases All subsequent credit releases must be approved by the DE, in consultation with the IRT, once performance standards have been met or exceeded. Implementation of the approved Mitigation Plan must be initiated no later than the first full growing season after the date of the first credit transaction (credit sale). For streams, a reserve of 10% of the site total stream credits will be released after four bankfull events have occurred, in separate years, provided the channel is stable and all other performance standards are met. In the event that less than four bankfull events occur during the monitoring period, release of these reserve credits is at the discretion of the IRT. 3.4 Financial Assurances The Bank Sponsor will provide financial assurances in the form of a casualty insurance policy or a performance bond. The financial assurance policy will be submitted for review and approval by the USACE and Office of General Counsel (OGC) prior to completion of the final MBI. Upon establishment, the USACE will hold the original policy document to ensure bank compliance and successful project site completion. Financial assurances shall be payable at the direction of the USACE to his designee or to a standby trust. Financial assurances structured to provide funds to the USACE in the event of default by the Bank Sponsor are not acceptable. A financial assurance must be in the form that ensures that the USACE receives notification at least 120 days in advance of any termination or revocation. 4 Ecological Suitability of the Site 4.1 Existing Conditions 4.1.1 Watershed Characterization The project site is situated within the Grassy Creek watershed in the southeastern portion of Surry County, NC. The project reaches include unnamed tributaries to Grassy Creek. The Grassy Creek drainage flows south to its confluence with the Yadkin River approximately three miles downstream. Grassy Creek is classified by the NCDEQ Division of Water Resources as Water Supply IV Watershed (WS-IV) waters within project area downstream to its confluence with Yadkin River. The project areas consist of mostly pasture and forested areas. The surrounding tributaries that flow directly into Grassy Creek are largely undeveloped on parcels that are privately owned. However, development pressure exists within the watershed. The proposed project would extend the wildlife corridor and protect aquatic and terrestrial habitat in the area through a permanent conservation easement. 4.1.2 Physiography, Geology, and Soils The project site is located in the Northern Inner Piedmont (45e) Level IV Ecoregion. The rolling to hilly Northern Inner Piedmont is characterized by higher elevations, more rugged topography, higher stream gradients and more mountain outliers than other areas of the Piedmont province. The underlying geology consists of Metagraywacke and Muscovite-Biotite Schist (‘CZmg’) (Geologic Map of North Carolina, NC WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Page 10 Geological Survey). Metagraywacke (biotite gneiss) is interlayered and gradational with muscovite-biotite schist; minor marble and granitic rock. As shown on the NRCS Soils Map (Figure 4), existing floodplain soils surrounding the project reaches are mostly within the mapping units FfD (Fairview), FtE (Fairview-Stott Knob complex), and FnC2 (Fairview). Fairview and Fairview-Stott Knob soils are well drained with high runoff potential. The majority of the site’s floodplain consists of Fairview soils, cobbly fine sandy loam, 15-25 percent slopes, stony. Fairview- Stott Knob soils are found along steep slopes (25% to 45%). 4.1.3 Existing Jurisdictional Waters of the US The streams at the Project were broken down into nine reaches (S100-R1, S100-R2, S100-R3, S100-R4, S101-R1, S101-R2, S200-R1, S200-R2, and S201) totaling approximately 4,963 linear feet of existing streams. Project reaches were differentiated based on drainage area breaks at confluences, changes in restoration approaches and/or property boundaries. Preliminary (unverified) field evaluations determined that project reaches S100-R2, S100-R3, S100-R4, S200-R1, and S200-R2 are perennial streams. S100-R1, S101-R1, S101-R2, and S201 are intermittent streams. The presence of historic valleys for each of the project stream reaches can be seen from LiDAR imagery (Figure 5), and are obvious through field observation. These evaluations were based on NCDWR’s Methodology for Identification of Intermittent and Perennial Streams and Their Origins, (v4.11, Effective Date: September 1, 2010) stream assessment protocols. WLS will submit a Preliminary Jurisdictional Determination request prior to the Mitigation Plan development phase. Table 3.

The results of the cross- section surveys and the visual field evaluations were used to conduct geomorphic stream classification WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Water & Land Solutions Page 11 and assess channel stability for each of the project stream reaches. Site reaches were also assessed using the NC Stream Assessment Method (NC SAM) (Appendix A). The summary of the morphological parameters and NC SAM are located in Table 4. Table 4. Existing Reach Description Project Reach Designation Existing Length (LF) Entrenchment Ratio (ER) Width/Depth Ratio (W/D) Bank Height Ratio (BHR) Existing Channel Type (Rosgen Classification) NC SAM Rating S100-R1 322 2.18 25 1.0 B4a High S100-R2 1,905 1.32, 1.45 4.77, 7.51 2.47, 3.43 B4, G4 Low S100-R3 785 1.18 17.39 2.31 F4b Low S100-R4 604 2.29 18.98 1.0 C4 High S101-R1 255 1.42 12.07 1.88 B4a Medium S101-R2 178 1.62 5.42 5.68 B4a Low S200-R1 398 1.11 18.34 4.92 F4b Medium S200-R2 356 1.92 22.25 1.0 B4 High S201 160 1.46 6.00 2.01 B4 Low The existing project streams have been degraded because of historic and current land use practices, including agriculture. Agricultural practices, including regular channelization, streambank maintenance, and animal husbandry have severely impacted the streambanks along many of the project stream reaches. Most of the project streams are incised and unstable, with documented channel manipulations (i.e. straightening, widening) and associated bank erosion. Clearing of stream buffers for agricultural purposes has removed or reduced high functioning riparian buffers. Currently, the project reaches act as significant sources of sediment and nutrient contamination to the watershed, as well as the receiving waters. S100-R1: S100-R1 is an intermittent tributary that begins just below a small farm pond along the northern project boundary. The reach flows south for approximately 322 feet to the current ford crossing. The valley slope in this reach is approximately 5.8 percent and the drainage area is 9.47 acres. The channel is vertically and horizontally stable with significant portion of the bed containing gravel substrate. The riparian buffer is a minimum of 50 feet wide on the left floodplain throughout the entire reach length, and the right floodplain is less than 50 feet. Cattle have unrestricted access to this area. Based on the existing conditions, the reach is classified as an incised Rosgen ‘B4a’ stream type. S100-R2: S100-R2 continues to flow south below S100-R1 for approximately 1,905 feet before terminating into S100-R3. A portion of the reach is impacted by a large farm pond. The valley slope in this reach is approximately 3.5 percent and the drainage area is 51.7 acres. The reach is highly incised (BHR = 2.4) and entrenched (ER = 1.3) and continues to downcut causing excessive bank failures and erosion. In some areas the riparian buffer exceeds 50 feet but much of the buffer is sparse with few trees and contains WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Page 12 many invasive species. Based on the existing conditions and gravel bed material, the reach in this section is classified as an incised Rosgen ‘B4/G4’ stream type. S100-R3: S100-R3 continues to flow south below the confluence of S100-R2 and S200 for approximately 785 feet before terminating into S100-R4. The valley slope is approximately 2.3 percent, and the drainage area is 159.2 acres. The reach is highly incised (BHR = 2.3) and entrenched (ER = 1.2) and was moved out of its natural valley against the valley wall to accommodate a larger agricultural pasture. The riparian buffer is a minimum of 50 feet wide on a majority of the right bank, and there is very little buffer on the left floodplain. There are heavy stands of invasive species throughout the corridor. Based on the existing conditions, the reach is classified as a Rosgen ‘F4b’ stream type. S100-R4: S100-R4 continues to flow south for approximately 604 feet before terminating at the southernmost project boundary. The reach has a drainage area of 174.2 acres and a valley slope of approximately 2.3 percent. The reach is highly sinuous (k=1.48) for the valley type. The channel has been relatively undisturbed, with minimal erosion along the stream banks. As a result, this reach is highly stable, with high bedform diversity and BHRs that are near 1.0. Cattle do not have access to this stream reach. Based on the current conditions and coarse gravel/small cobble, the reach is classified as a Rosgen ‘C4’ stream type. S101-R1: S101-R1 starts as a small intermittent headwater tributary along the eastern project boundary. This reach flows west for approximately 255 feet to the reach break S101-R2. The reach has a small drainage area of 7.3 acres and a valley slope of approximately 7.2 percent. The reach is incised (BHR = 1.9) and entrenched/moderately entrenched (ER = 1.4.) but has a relatively stable bed and stream banks. There is some riparian buffer on each side of the channel. Cattle have unrestricted access to this area. Based on the current conditions and gravel substrate, the reach is classified as a Rosgen ‘B4a’ stream type. S101-R2: S101-R2 continues to flow west below S101-R1 for approximately 178 feet before the confluence into S100-R3. The reach has a valley slope of 7.2 percent and drainage area of 8.3 acres. The channel is severely incised (BHR = 5.7) and moderately entrenched (ER = 1.6.) Mature woody vegetation is absent along most of this reach, and cattle currently have direct access which has led to growth of sparse understory vegetation. Based on the existing channel conditions and anthropogenic disturbances, the reach is classified as an incised Rosgen ‘B4a’ stream type. S200-R1: S200-R1 begins at a property line along the western project boundary and flows southeast for approximately 356 feet to S200-R2. The reach has a valley slope of 4.5 percent and drainage area of 48.8 acres. The channel is severely incised (BHR = 4.9) and entrenched (ER = 1.1.) While the channel has large cobble present stabilizing the bed, active bank erosion and slumping are contributing fine sediment into the channel degrading the in-stream habitat. The riparian buffer exceeds 50 feet on both sides of the channel, but cattle have destroyed much of the woody and herbaceous understory. Based on the existing channel conditions and anthropogenic disturbances, the reach is classified as an incised Rosgen ‘F4b’ stream type. S200-R2: S200-R2 continues to flow southeast below S200-R1 for approximately 178 feet before the confluence with S100-R3. The reach has a valley slope of 4.9 percent and drainage area of 50.5 acres. The channel is stable both horizontally and vertically with areas of large bedrock knickpoints. The reach is not incised and slightly entrenched (ER = 1.9.) The stream channel has been relatively undisturbed, with minimal erosion along the stream banks. As a result, this reach is stable with high bedform diversity. The WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Water & Land Solutions Page 13 riparian buffer is dominated by small woody shrubs and heavy herbaceous cover with a few larger trees scattered throughout the reach. Based on the current conditions and gravel substrate, the reach is classified as a Rosgen ‘B4’ stream type. S201: S201 is a small intermittent headwater tributary that originates along the westernmost property boundary and flows east for approximately 160 feet before the confluence with S200. The channel is classified as intermittent but exhibits consistent bed and bank features and flows within its natural valley. S201 has a drainage area of approximately 9.1 acres and the valley slope is 10.4 percent. The channel is severely incised (BHR = 2.0) and moderately entrenched (ER = 1.5.) The reach has a large riparian buffer (>50 feet), but little understory growth due to the presence of cattle. Based on the current conditions and gravel substrate, the reach is classified as a Rosgen ‘B4’ stream type. 4.1.5 Existing Wetland Conditions Unverified riparian wetland areas were identified along the S100-R2 floodplain: W01 (0.022 acres), W02 (0.025 acres), and W03 (0.112 acres). A detailed wetland delineation has been performed, but not submitted to the USACE for verification. The site will be reviewed and approved by the U.S. Army Corps of Engineers (USACE) before the mitigation plan phase of the project. There are no proposed wetland mitigation areas on this project or wetland mitigation credits. 4.2 Regulatory Considerations 4.2.1 Existing Easements There are no other existing easements on the site, except for a powerline above S100-R3 and this area will be removed from the conservation easement. The proposed conservation easement has three additional easement breaks for farm crossings. 4.2.2 Mineral or Water Rights Assurance There are no known mineral or surface water rights issues within or adjacent to the site properties. 4.2.3 FEMA Floodplain Compliance and Hydrologic Trespass The lower portion of S100-R4 is located within the FEMA regulated floodplain (“Zone AE”) (Figure 7). Because S100-R4 is a preservation reach no work will be conducted and thus no impacts will be made to the FEMA regulated floodplain. While it is not anticipated that there will be issues associated with FEMA permitting or documentation, WLS will coordinate with the local floodplain administrator as needed and prepare the required documentation to obtain approval for any FEMA regulated impacts. In addition, the project will be designed so that any increase in flooding will be contained within the project boundary and will not impact adjacent landowners, therefore hydrologic trespass will not be a concern. 4.2.4 Invasive Species Vegetation There are individual or small clumps of Chinese privet (Ligustrum sinense) located along S100-R2 and S101- R1. Chinese privet is denser along the buffer of S100-R3, S101-R2, and S200-R2. There are sparse areas of multiflora rose throughout the project area as well. Chinese privet and multiflora rose will be removed as part of the overall restoration approach. After restoration, these areas will be monitored, and any invasive WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Page 14 plants found within the project boundary will be treated to prevent expansion and establishment of a substantial invasive community. This will allow for a healthy, native riparian and upland plant community to dominate the area and help prevent future establishment of invasive species vegetation. 4.2.5 Cultural Resources & Aviation The project is not anticipated to have any adverse impacts on cultural or historic resources. There are no sites currently listed on the National Register of Historic Places (NRHP) within the project area. The nearest site is the Houston Marion House (HPO Site ID: SR0134) which is approximately 0.15 miles from the project site. This home is listed as ‘Gone?’ and is on the other side of State Road 2048. On-site investigations and discussions with the landowner have not disclosed any potential resources or occurrences of this type on the property. The environmental screening phase of the Project will include NC State Historic Preservation Office (SHPO) coordination to confirm these findings. Based on a review using Google Earth, there are no airports within a five-mile radius. The project is not anticipated to affect aviation. 4.2.6 Threatened and Endangered Species Based on a review of the US Fish and Wildlife Service (USFWS) database and IPAC, there are currently five federally-listed threatened and endangered species known to occur in Surry County: Northern long-eared bat (Myotis septentrionalis; endangered), gray bat (Myotis grisescens; endangered), tri-colored bat (Perimyotis subflavus; proposed endangered), bog turtle (Glyptemys muhlenbergii; similarity of appearance threatened), and Schweinitz’s sunflower (Helianthus schweinitzii; endangered). No potential protected species occurrences were observed during initial site investigations. Project implementation is not anticipated to have a negative impact on these species. WLS will coordinate with the appropriate agencies should a determination be required for permitting. 4.2.7 Conditions Affecting Hydrology Within the project area there is a large farm pond on S100-R2 and three existing ford crossings (S100-R2, S101-R1, and S100-R3). The farm pond will be removed, and a new channel will be designed within the pond’s footprint. The three crossings will remain, but will be replaced with a culvert crossing. 4.2.8 Adjacent Land Use Site-adjacent land use is primarily agricultural and forested. None of these land uses will have negative impacts on the operation of the site. 5 Mitigation Work Plan 5.1 Site Design Approach The project will involve the restoration, enhancement, and preservation of nine stream reaches (S100-R1, S100-R2, S100-R3, S100-R4, S101-R1, S101-R2, S200-R1, S200-R2, and S201) totaling approximately 4,963 linear feet (Figure 8). The Project appropriately addresses all of the jurisdictional stream reaches at the project site, including restoring riparian buffers along all of the project stream reaches currently in agriculture and pasture. Due to past downcutting and overwidening associated with channelization, grade control along the project reaches appears to be provided by ford crossings and bedrock knickpoints. Some WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Water & Land Solutions Page 15 of the project reaches are highly unstable, with associated channel degradation and widespread stream bank erosion. Many of the riparian buffers have been disturbed and completely or partially cleared. The proposed project will provide adequate floodplain access to all stream reaches. Priority Level I and II Restoration is proposed along the restoration reaches to reconnect the project streams with their geomorphic floodplains. In upper and lower transition sections, the following elements will be incorporated into the Priority Level II Restoration design and construction: • Floodplain bench excavation grading will extend a minimum of 1.5 bankfull widths beyond the stream belt width such that meandering floodplains are not created. • All proposed floodplains will be constructed such that they are over-excavated to accommodate replacement of topsoil. • Design and construction oversight measures will ensure the proper harvesting, segregating, stockpiling, storage, handling, overall management and replacement of A and B soil horizon materials onto the excavated floodplain. • Constructed return slopes between the outer edge of the excavated floodplain and the terrace will be a minimum of 3:1 or flatter. The Project will provide increased floodplain access throughout the project area for all reaches and will be monitored to demonstrate successful floodplain function. The stream channel design will include analysis of the hydrology, hydraulics, shear stress, sediment transport, and bankfull channel dimensions. WLS will consider three methods (field indicators if present, published regional curve information, and hydraulic modeling) for estimating a bankfull discharge. The hydrology and hydraulics analysis will evaluate a range of lower flow discharges and flood frequency curves to help determine an appropriate design discharge. The design discharge will be used to select an appropriate channel geometry and help monitor long-term project performance. Sediment Transport Considerations The project reaches were observed to be predominantly gravel bed, with some larger cobble materials in a few locations. Sediment transport calculations and stream power analyses will be performed for both the existing channels and the proposed design channels. WLS will assess the stream’s transport capacity and competency to quantify the stream’s ability to transport its sediment load. WLS will perform quantitative channel assessments that includes collecting sediment samples and predicting streambank erosion rates and comparing model results using the BANCS Method (BEHI/NBS) to evaluate bed and bank material characteristics and estimate sediment yields. WLS will also perform watershed analysis to estimate how much sediment is being supplied to the project reaches by determining load rates from upland sources. The substrate material will be sieved and a grain size distribution developed. The results of the sediment transport analyses will be used to classify the streams, and complete critical shear stress calculations required for designing slopes/depths and predicting channel stability. Stream and Floodplain Improvement Features Stream improvement features such as in-stream structures and bioengineering techniques are proposed for grade control, streambank protection, and improving bedform diversity and aquatic habitat. All in- stream structures will be constructed from materials naturally found in the region such as hardwood trees, trunks/logs, brush/branches, and gravel stone materials. In order to ensure sustainability of these WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Page 16 structures, WLS will use design and construction methods that have proven successful on numerous past projects in the same geographic region and similar site conditions. WLS will also incorporate bioengineering practices, when appropriate, that use biodegradable materials and fabrics, uncompacted soils, live plant cuttings, and native species vegetation to stabilize streambanks. Bioengineering allows for the quick establishment of deep-rooted vegetation along the newly restored streambanks. Once established, these live, dormant plant cuttings will provide long-term bank stability to the treated areas and prevent further bank erosion and sedimentation. Floodplain features such as depressions, sloughs, meander scars, vernal pools, and tree throws are commonly found in natural riparian systems. These floodplain features will be incorporated to improve aquatic and terrestrial habitat and serve as water storage and sediment sinks. Site Access and Constructability WLS has field verified that the site has adequate construction access. Where practicable, impacts to existing native riparian buffer vegetation will be minimized. Any potential impacts to existing wetland areas will be avoided as practicable during construction, with only temporary, minimal impacts expected only as necessary for maximized permanent stream, wetland, and riparian buffer functional uplift. 5.2 Proposed Stream Conditions Restoration S100-R2: Work along S100-R2 will involve excavating a bankfull bench before raising the bed elevation and reconnecting the stream with its geomorphic floodplain. The channel will be restored in its current valley location. The existing pond will be removed, and both the stream and valley will be restored to predevelopment conditions. Since the reach is heavily incised, proposed grading activities will initially involve a shallow Priority Level II Restoration approach by gradually raising the bed elevation and reconnecting the stream with its constructed floodplain. The reach will be restored as a Rosgen ‘B4’ stream type using appropriate step-pool morphology with a moderate meander planform geometry that accommodates the valley slope and width. The design approach will restore a stable channel form with appropriate bedform diversity, as well as improved ecological function through increased aquatic and terrestrial habitats. The design width/depth ratio will be similar to stable streams in this geologic setting. In-stream structures will be incorporated to dissipate flow energies, protect streambanks, and eliminate the potential for further bank erosion. In- stream structures may include constructed riffles for grade control and aquatic habitat, log j-hook vanes, log vanes, and angled log drops for increasing pool formation, bank stability, and bedform diversity. Existing stream substrate will be harvested and reused for in-stream structures where available and appropriate. Riparian buffers of at least 50 feet wide will be maintained and/or supplementally planted along the entire reach. Chinese privet will be removed in this area and native riparian species vegetation will be planted in the resulting disturbed areas. Permanent fencing will be installed to exclude livestock and reduce sediment and nutrient inputs. S100-R3: Work along S100-R3 will involve a Rosgen Priority Level I Restoration approach. S100-R3 is incised with multiple active headcuts and has also been moved to the valley edge to increase adjacent WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Water & Land Solutions Page 17 agricultural pasture. The channel will be moved back to the center of the valley to allow greater access to the natural floodplain. The reach will be restored as a Rosgen ‘B4’ stream type using appropriate step- pool morphology with moderate planform geometry that accommodates the valley slope and width. Proposed in-stream structures will include constructed wood and stone riffles for grade control and habitat, brush toe, cover logs, and angled log steps for encouraging step-pool formation, energy dissipation, bank stability, and bedform diversity and to provide natural scour features and improved aquatic habitat. A permanent culverted stream crossing will be improved at the same location to replace the existing ford stream crossing downstream of S101-R2 to allow access between pastures. The existing unstable channel will be filled with suitable fill material and a new bankfull channel will be built offline connecting it to its geomorphic floodplain. Shallow depressional areas will provide habitat diversity, temporary sediment storage and improved treatment of overland flows. Permanent fencing will be installed to exclude livestock and reduce sediment and nutrient inputs. Any invasive species vegetation will be removed and native riparian species vegetation will be planted within the conservation easement. Riparian buffers in excess of 50 feet will be restored and protected along the entire length of the reach. S101-R2: Work along this reach will involve stabilizing a headcut below the existing ford crossing with in- stream drop structures and creating appropriate pool spacing and a stable connection with S100-R3. The channel is straightened and downcut along most of the reach and will be restored as a step-pool system within the current alignment before transitioning to S100-R3. A permanent culverted stream crossing will be improved at the same location to replace the existing ford stream crossing. Riparian buffers will be planted a minimum of 50 feet from the top of banks and protected along the entire reach length. Chinese privet will be removed in this area and native riparian species vegetation will be planted in the resulting disturbed areas. Permanent fencing will be installed to exclude livestock and reduce sediment and nutrient inputs. S200-R1: S200-R1 is both incised and entrenched and has downcut to the larger parent material. Work will involve a Priority I and II restoration approach by excavating a bankfull bench before raising the bed elevation and reconnecting the stream with its geomorphic floodplain. The channel is straightened and downcut along the entire length and will be restored as a step-pool system within the current alignment before transitioning to S200-R2. Riparian buffers of at least 50 feet wide will be maintained and/or supplementally planted along the entire reach. Any invasive species vegetation will be removed in this area and native riparian species vegetation will be planted in the resulting disturbed areas. Permanent fencing will be installed to exclude livestock and reduce sediment and nutrient inputs. S201: S201 is a small headwater tributary that is both incised and entrenched. Lack of in-channel substrate and vegetation on the banks exacerbate the channel degradation. Work will on this reach will involve a Priority I restoration connecting it back to its natural floodplain. The channel is straightened and downcut along the entire length and will be restored as a step-pool system within the current alignment before transitioning to S200-R1. The restored channel will follow the historic flow pattern and spread out through channel depressions during higher flow events, providing a more natural hydrologic function. Riparian buffers will be planted a minimum of 50 feet from the top of banks and protected along the entire reach length. WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Page 18 Enhancement Level II S100-R1: Work along reach S100-R1 will involve Enhancement Level II practices to improve the current riparian buffer conditions and prevent future cattle trampling. These areas have been historically disturbed through agricultural practices, however the stream channel exhibits stable conditions throughout most of their length. The existing ford crossing on S100-R1 will be improved to a culverted stream crossing to allow the landowner access to the northwest property corner. Riparian buffers of at least 50 feet wide will be maintained and/or supplementally planted along the entire reach. Additionally, permanent fencing will be installed or improved to permanently exclude livestock and reduce direct sediment and nutrient inputs. Any exotic species vegetation will be removed in this area and native riparian species vegetation will be planted in the resulting disturbed areas. S101-R1: Due to the limited past disturbances and current condition of S101-R1, an Enhancement Level II approach is proposed to reduce isolated bank erosion and prevent future cattle trampling. Most of the reach has adequate riparian buffer vegetation and exhibits a stable step-pool morphology. The bed material consists of large gravel material which provides adequate grade control as the reach transitions into S101-R2. Riparian buffers of at least 50 feet wide will be maintained and/or supplementally planted along the entire reach. Additionally, permanent fencing will be installed or improved to permanently exclude livestock and reduce direct sediment and nutrient inputs. Any exotic species vegetation will be removed in this area and native riparian species vegetation will be planted in the resulting disturbed areas. S200-R2: S200-R2 starts immediately below S200-R1 and flows east to its confluence with S100-R3. Work on this reach will involve Enhancement Level II practices to provide a stable connection with S200-R1 and improve the stability of the channel. Currently the reach is mostly stable, but experiencing hoof shear and minor bank erosion/trampling. This enhancement approach will exclude cattle and allow the reach to naturally create a stable channel form with appropriate bedform diversity, as well as improved ecological function through increased aquatic and terrestrial habitats. Permanent fencing will be installed to exclude livestock and reduce sediment and nutrient inputs. Riparian buffers of at least 50 feet wide will be maintained and/or supplementally planted along the entire reach. Any exotic species vegetation will be removed in this area and native riparian species vegetation will be planted in the resulting disturbed areas. Preservation S100-R4: Preservation is being proposed along S100-R4 since the existing stream system is stable with a mostly mature riparian buffer due to limited historic impacts. S100-R4 will be protected in perpetuity through a conservation easement. Any exotic species vegetation will be removed and a 100-foot-wide riparian buffer where possible will permanently protected the reach. Cattle are currently excluded from this reach and will continue to be excluded. Water Quality Improvement Features WLS may implement water quality improvement features as practices or measures as part of a comprehensive watershed restoration approach. When implemented collectively along with stream, riparian buffer, and riparian wetland restoration, these water quality improvement features can be effective agricultural BMPs that reduce pollutants from concentrated flows, particularly nutrient and sediment loadings from cattle pastures, and therefore provide additional ecological uplift to the project. The features will be excavated along the project reaches at non-jurisdictional or depressional areas where WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Water & Land Solutions Page 19 ephemeral drainages intersect with the project boundary. WLS will identify potential locations for water quality improvement features following the topographic survey. 5.2.1 Proposed Revegetation Plan Riparian buffers will be established a minimum of 50 feet from the top of the streambanks along each of the Project reaches, as well as permanently protecting those buffers with a conservation easement. Many of the proposed riparian buffer widths within the conservation easement are greater than 50 feet along one or both streambanks to provide additional functional uplift potential, such as encompassing adjacent wetland areas. Proposed plantings will be conducted using native species trees and shrubs, in the form of live stakes and seedlings will predominantly consist of bare root vegetation planted at a total target density of 680 stems per acre. The proposed plant selection will help to establish canopy cover and soil stability based on an appropriate reference community. Schafale’s (2023) guidance on vegetation communities for Mesic Mixed Hardwood Forest (Piedmont Subtype) and the USACE Wetland Research Program (WRP) Technical Note VN-RS-4.1, as well as existing mature species identified throughout the project area, will be referenced during the development of riparian buffer and adjacent riparian wetland plants for the Project site. 5.3 Reference Ecosystems Reference ecosystems will be identified and surveyed that represent similar conditions to the restored stream system. Stream channel geometry and morphologic relationships will be based on published regional curve relationships, reference reach information and empirical data from successful past projects. 6 Potential Functional Uplift & Ecological Benefits 6.1 Benefits Related to Hydrology The potential functional uplift and ecological benefits to impairments are summarized below as part of the overall project goals. • Floodplain Connectivity – A Priority Level I Restoration approach will reconnect channels with their active and/or relic floodplains and improve stream and wetland hydrology to areas that have been degraded and/or been historically manipulated. • Surface Storage and Retention – The restored streams will be raised and reconnected to their active or relic floodplains to restore hydrology and to spread higher flow energies onto the floodplain thereby increasing retention time, storage, and roughness. Incorporation of depressional areas and other floodplain features will provide additional retention, storage and habitat diversity and uplift. Native species riparian vegetation will be established throughout the riparian buffer corridor. • Groundwater Recharge and Hyporheic Exchange – The restored riparian buffers and microtopography will increase infiltration and improve overall hydrogeologic function. Benefits will be achieved through the establishment of vegetated buffers which increase groundwater infiltration, surface water interaction and recharge rates. WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Page 20 • Proper Channel Form – Restoring an appropriate dimension, pattern, and profile will efficiently transport and deposit sediment (point bars and floodplain sinks) relative to the stream power and load that is supplied from banks, adjacent uplands, and watershed. Stream channels that are appropriately sized to convey flows and sediment load will greatly improve channel stability by reducing bed degradation and aggradation. • In-stream Structures – In-stream structures, such as angled log step-pools, log vanes, j-hook vanes, toe wood and constructed riffles made from native woody and rock materials, will help to control grade and reduce bank erosion by diverting shear stress away from streambanks during storm events. • Sediment Transport – Boundary conditions, land use, climate, and geologic controls influence stream channel formation, migration, and how sediment is transported through its watershed. Appropriate transport capacity, flow competency and bed material size will ensure sediment is more evenly distributed, such that excessive degradation and aggradation do not occur. Adequately transporting or entraining fine-grain sediment will prevent embeddedness and create interstitial habitat and in-stream cover within riffle areas. 6.2 Benefits Related to Habitat • Proper channel form – Restoring an appropriate bedform and geometry will efficiently transport and deposit sediment (point bars and floodplain sinks) relative to the stream power and load that is supplied from banks and uplands. Stream channels that are appropriately sized to convey smaller storm flows will greatly improve channel stability by reducing active bank erosion (lateral stability) and bed degradation (vertical stability, i.e., headcuts, downcutting, incision). • Terrestrial and Aquatic Habitat – Benefits will be achieved through the incorporation of physical structures, removal of invasive species and re-establishing and enhancing native vegetation to the riparian buffer areas. Benefits to aquatic organisms will be achieved through the installation of appropriate in-stream structures using native rock material and woody debris. Adequately transporting and depositing fine-grain sediment onto the floodplain will prevent embeddedness and create interstitial habitat, organic food resources and in-stream cover. In-stream habitat will be improved by creating deeper pools and areas of re-aeration. These lotic systems can provide sources of organic matter that ultimately improve the biodiversity of downstream river systems. • Landscape Connectivity – Benefits to landscape connectivity will be achieved by restoring a healthy stream corridor, promoting aquatic and terrestrial species migration and protecting their shared resources in perpetuity. 6.3 Benefits Related to Water Quality • Nutrient Reduction/Native Buffer Vegetation – Currently, excess nutrients and pollutants such as nitrogen/phosphorus from agricultural practices are entering many of the project reaches without adequate riparian buffers (fragmentation). High-functioning riparian buffer vegetation will be established or enhanced and permanently protected to remove direct pollutant sources and filter runoff prior to entering the project reaches. WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Water & Land Solutions Page 21 • Sediment Reduction – Benefit will be achieved through stabilization of eroding banks; installation of vegetated buffers; and by dissipating excess flow energy and shear stress with increased overbank flows during storm events. • DO, NO3-, DOC Concentration – Benefits will be achieved through the restoration of more natural stream bedforms, including riffle and pool sequences, which will increase dissolved oxygen (DO) concentrations. In addition, as planted riparian buffers mature, increased shade and wider vegetation density/structure will reduce water temperatures and groundwater nitrates (NO3-) as well as increase dissolved organic carbon (DOC). • Bioengineering Treatments – Bioengineering practices such as live staking, brush layering, and vegetated soil lifts will provide lateral bank stability, rapid tree growth and bank shading to reduce water temperatures, bank erosion and increase dissolved oxygen levels. 7 Credit Determination 7.1 Proposed Credit Types Expected credit types are Stream Mitigation Credits (SMCs). SMCs (Warm Thermal Regime) will be generated through Stream Restoration, Enhancement, and Preservation (Table 5). Table 5. Proposed Stream Mitigation Credits (SMCs) Reach Designation Type of Mitigation Proposed Stream Length (LF) Ratio Stream Mitigation Credits (SMCs) S100-R1 Stream Enhancement II 322 5:1 64.40 S100-R2 Stream Restoration (PI/PII) 1,905 1:1 1,905.00 S100-R3 Stream Restoration (PI) 785 1:1 785.00 S100-R4 Stream Preservation 604 10:1 60.40 S101-R1 Stream Enhancement II 255 5:1 51.00 S101-R2 Stream Restoration (PI) 178 1:1 178.00 S200-R1 Stream Restoration (PI/PII) 398 1:1 398.00 S200-R2 Stream Enhancement II 356 5:1 71.20 S201 Stream Restoration (PI) 160 1:1 160.00 Total 4,963 3,673.00 Note 1: No mitigation credits are proposed outside the conservation easement boundaries. 8 Monitoring Stream stability, hydrology, and vegetation survival will be monitored across the Project to determine the success of the stream and wetland mitigation. Monitoring and performance standards will follow the guidance provided in the 2016 USACE Wilmington District Stream and Wetland Compensatory Mitigation Update. Stream stability will be monitored with cross-section surveys and visual assessment stream walks. Stream hydrology will be monitored with gauges. Vegetation survival rates will be monitored using vegetation plots over approximately two percent of the planted area. WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Page 22 8.1 As-Built Survey An as-built survey will be conducted following construction to document channel size, condition, and location on constructed or modified channels. The survey will include a complete profile of thalweg, water surface, bankfull, and top of bank to compare with future geomorphic data. Longitudinal profiles will not be required in annual monitoring reports unless requested by the USACE. 8.2 Visual Monitoring Visual monitoring of all mitigation areas will be conducted a minimum of twice per monitoring year by qualified individuals. The visual assessments will include vegetation density, vigor, invasive species, and easement encroachments. Visual assessments of stream stability will include a complete a stream walk and structure inspection. Photographs will be taken at fixed representative locations (cross-sections, enhancement reaches, and crossings) to record each monitoring event, as well as any noted problem areas or areas of concern. Results of visual monitoring will be presented in a plan view exhibit with a brief description of problem areas and digital images. Photographs will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal photos should indicate the absence of developing bars within the channel or an excessive increase in channel depth. Lateral photos should not indicate excessive erosion or continuing degradation of the banks over time. A series of photos over time should indicate successional maturation of riparian vegetation. 8.3 Channel Dimension Permanent cross-sections will be installed at a minimum of one per 20 bankfull widths with half in pools and half in riffles. All cross-section measurements will include bank height ratio and entrenchment ratio. Cross-sections will be monitored annually. There should be little change in as-built cross-sections. 8.4 Flow Duration Monitoring Monitoring of stream flow will be conducted to demonstrate that the restored stream systems classified as intermittent exhibit surface flow for a minimum of 30 consecutive days throughout some portion of the year during a year with normal rainfall conditions. The proposed monitoring of restored intermittent reaches will include the installation of flow devices (continuous-read pressure transducers) within the thalweg (bottom) of the channel towards the upper-third portion of the reach. 8.5 Vegetation Vegetation monitoring plots will be a minimum of 0.02 acres in size and cover approximately two percent of the restoration planted area. This does not include areas that are supplementally planted due to existing vegetation. The following data will be recorded for all trees/shrubs in the plots: species, height, planting date (or volunteer), and grid location. Monitoring will occur each year during the monitoring period. The interim measures of vegetative success for the sites will be the survival of at least 320 planted three-year old trees per acre at the end of Year 3 and 260 five-year old trees per acre at the end of Year 5. The final vegetative success criteria will be the survival of 210 trees per acre with an average height of 10 feet at the end of Year 7 of the monitoring period. WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Water & Land Solutions Page 23 9 Long-Term Management 9.1 Maintenance The Project will be protected in perpetuity by a recorded conservation easement. The conservation easement will allow for annual site inspections during the post-construction monitoring period. These site inspections may identify components and features that require routine maintenance. The site will be monitored on a regular basis and a physical inspection will take place at least once a year throughout the post-construction monitoring period until performance standards are met. Routine post-construction maintenance may include the following components as described in Table 6. Table 6. Routine Maintenance Components Feature Maintenance Activity Through Close -out Stream Routine channel maintenance and repair activities may include modifying in-stream structures to prevent piping, securing loose coir matting, and supplemental installation of live stakes and other target vegetation along the Project reaches. Areas of concen trated stormwater and floodplain flows that intercept the channel may also require maintenance. Beaver Management Routine maintenance and repair activities caused by beaver activity may include supplemental planting, pruning, and dewatering/dam removal. Beaver management will be implemented using accepted trapping and removal methods only within the recorded Conservat ion Easement. Vegetation Vegetation will be maintained to ensure the health and vigor of the targeted plant community. Routine vegetation maintenance and repair activities may include supplemental planting, pruning, and fertilizing. Exotic invasive plant species will be treated by mechanical and/or chemical methods. Any invasive plant species control requiring herbicide application will be performed in accordance with NCDA rules and regulations. Project Site Boundary Project boundaries will be demarcated in the field to ensure clear distinction between the Project site and adjacent properties. Boundaries may be identified by fence, marker, bollard, post, or other means as allowed by Project conditions and/or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as needed basis. Stream Crossing The stream crossings within the Project may be maintained only as allowed by the recorded Conservation Easement, deed restrictions, rights of way, or corridor agreements. Stream crossings will be excluded from the easement area and maintained by the landowner. 9.2 Long-Term Management Upon final IRT approval and project closeout, the site will be transferred to a long-term land steward. The responsible party for long-term management has not yet been chosen, but will be approved by the DE and IRT prior to the bank establishment. The long-term management and land steward shall be responsible for periodic/routine inspection of the site to ensure that the conservation easement and/or the deed restrictions are being upheld. Any endowment funds for the conservation easement and deed restrictions shall be negotiated prior to site transfer to the responsible party. The management activities will be conducted in accordance with the terms and conditions of the approved UMBI as agreed to by WLS, USACE, and the IRT. WLS Yadkin 01 Umbrella Mitigation Bank - Miller Site Page 24 9.3 Adaptive Management Plan In the event the mitigation site or a specific component of the mitigation site fails to achieve the necessary performance standards as specified in the approved mitigation plan, the Sponsor shall notify the USACE and coordinate with IRT members to develop a remedial action plan. The Sponsor will also coordinate with the USACE to obtain authorization and approval to conduct the remedial action. The remedial action plan should describe the source or reason for the failure, a concise description of the corrective measures that are proposed, and a time frame for the implementation of the corrective measures. Additional monitoring, as prescribed by IRT guidance, may also be required to satisfy the performance standards.

List species: Designated Critical Habitat (list species) 19. Are additional stream information/supplementary measurements included in “Notes/Sketch” section or attached? Yes No 1. Channel Water – assessment reach metric (skip for Size 1 streams and Tidal Marsh Streams) A Water throughout assessment reach. B No flow, water in pools only. C No water in assessment reach. 2. Evidence of Flow Restriction – assessment reach metric A At least 10% of assessment reach in-stream habitat or riffle-pool sequence is severely affected by a flow restriction or fill to the point of obstructing flow or a channel choked with aquatic macrophytes or ponded water or impoundment on flood or ebb within the assessment reach (examples: undersized or perched culverts, causeways that constrict the channel, tidal gates, debris jams, beaver dams). B Not A 3. Feature Pattern – assessment reach metric A A majority of the assessment reach has altered pattern (examples: straightening, modification above or below culvert). B Not A 4. Feature Longitudinal Profile – assessment reach metric A Majority of assessment reach has a substantially altered stream profile (examples: channel down-cutting, existing damming, over widening, active aggradation, dredging, and excavation where appropriate channel profile has not reformed from any of these disturbances). B Not A 5. Signs of Active Instability – assessment reach metric Consider only current instability, not past events from which the stream has currently recovered. Examples of instability include active bank failure, active channel down-cutting (head-cut), active widening, and artificial hardening (such as concrete, gabion, rip-rap). A < 10% of channel unstable B 10 to 25% of channel unstable C > 25% of channel unstable 6. Streamside Area Interaction – streamside area metric Consider for the Left Bank (LB) and the Right Bank (RB). LB RB A A Little or no evidence of conditions that adversely affect reference interaction B B Moderate evidence of conditions (examples: berms, levees, down-cutting, aggradation, dredging) that adversely affect reference interaction (examples: limited streamside area access, disruption of flood flows through streamside area, leaky or intermittent bulkheads, causeways with floodplain constriction, minor ditching [including mosquito ditching]) C C Extensive evidence of conditions that adversely affect reference interaction (little to no floodplain/intertidal zone access [examples: causeways with floodplain and channel constriction, bulkheads, retaining walls, fill, stream incision, disruption of flood flows through streamside area] or too much floodplain/intertidal zone access [examples: impoundments, intensive mosquito ditching]) or floodplain/intertidal zone unnaturally absent or assessment reach is a man-made feature on an interstream divide 7. Water Quality Stressors – assessment reach/intertidal zone metric Check all that apply. A Discolored water in stream or intertidal zone (milky white, blue, unnatural water discoloration, oil sheen, stream foam) B Excessive sedimentation (burying of stream features or intertidal zone) C Noticeable evidence of pollutant discharges entering the assessment reach and causing a water quality problem D Odor (not including natural sulfide odors) E Current published or collected data indicating degraded water quality in the assessment reach. Cite source in “Notes/Sketch” section. F Livestock with access to stream or intertidal zone G Excessive algae in stream or intertidal zone H Degraded marsh vegetation in the intertidal zone (removal, burning, regular mowing, destruction, etc) I Other: (explain in “Notes/Sketch” section) J Little to no stressors 8. Recent Weather – watershed metric (skip for Tidal Marsh Streams) For Size 1 or 2 streams, D1 drought or higher is considered a drought; for Size 3 or 4 streams, D2 drought or higher is considered a drought. A Drought conditions and no rainfall or rainfall not exceeding 1 inch within the last 48 hours B Drought conditions and rainfall exceeding 1 inch within the last 48 hours C No drought conditions 9. Large or Dangerous Stream – assessment reach metric Yes No Is stream is too large or dangerous to assess? If Yes, skip to Metric 13 (Streamside Area Ground Surface Condition). 10. Natural In-stream Habitat Types – assessment reach metric 10a. Yes No Degraded in-stream habitat over majority of the assessment reach (examples of stressors include excessive sedimentation, mining, excavation, in-stream hardening [for example, rip-rap], recent dredging, and snagging) (evaluate for Size 4 Coastal Plain streams only, then skip to Metric 12) 10b. Check all that occur (occurs if > 5% coverage of assessment reach) (skip for Size 4 Coastal Plain streams) A Multiple aquatic macrophytes and aquatic mosses (include liverworts, lichens, and algal mats) B Multiple sticks and/or leaf packs and/or emergent vegetation C Multiple snags and logs (including lap trees) D 5% undercut banks and/or root mats and/or roots in banks extend to the normal wetted perimeter E Little or no habitat F 5% oysters or other natural hard bottoms G Submerged aquatic vegetation H Low-tide refugia (pools) I Sand bottom J 5% vertical bank along the marsh K Little or no habitat *********************************REMAINING QUESTIONS ARE NOT APPLICABLE FOR TIDAL MARSH STREAMS**************************** 11. Bedform and Substrate – assessment reach metric (skip for Size 4 Coastal Plain streams and Tidal Marsh Streams) 11a. Yes No Is assessment reach in a natural sand-bed stream? (skip for Coastal Plain streams) 11b. Bedform evaluated. Check the appropriate box(es). A Riffle-run section (evaluate 11c) B Pool-glide section (evaluate 11d) C Natural bedform absent (skip to Metric 12, Aquatic Life) 11c. In riffle sections, check all that occur below the normal wetted perimeter of the assessment reach – whether or not submerged. Check at least one box in each row (skip for Size 4 Coastal Plain streams and Tidal Marsh Streams).

LB RB A A Majority of streamside area with depressions able to pond water ≥ 6 inches deep B B Majority of streamside area with depressions able to pond water 3 to 6 inches deep C C Majority of streamside area with depressions able to pond water < 3 inches deep 15. Wetland Presence – streamside area metric (skip for Tidal Marsh Streams) Consider for the Left Bank (LB) and the Right Bank (RB). Do not consider wetlands outside of the streamside area or within the normal wetted perimeter of assessment reach. LB RB Y Y Are wetlands present in the streamside area? N N 16. Baseflow Contributors – assessment reach metric (skip for Size 4 streams and Tidal Marsh Streams) Check all contributors within the assessment reach or within view of and draining to the assessment reach. A Streams and/or springs (jurisdictional discharges) B Ponds (include wet detention basins; do not include sediment basins or dry detention basins) C Obstruction passing flow during low-flow periods within the assessment area (beaver dam, leaky dam, bottom -release dam, weir) D Evidence of bank seepage or sweating (iron in water indicates seepage) E Stream bed or bank soil reduced (dig through deposited sediment if present) F None of the above 17. Baseflow Detractors – assessment area metric (skip for Tidal Marsh Streams) Check all that apply. A Evidence of substantial water withdrawals from the assessment reach (includes areas excavated for pump installation) B Obstruction not passing flow during low-flow periods affecting the assessment reach (ex: watertight dam, sediment deposit) C Urban stream (≥ 24% impervious surface for watershed) D Evidence that the streamside area has been modified resulting in accelerated drainage into the assessment reach E Assessment reach relocated to valley edge F None of the above 18. Shading – assessment reach metric (skip for Tidal Marsh Streams) Consider aspect. Consider “leaf-on” condition. A Stream shading is appropriate for stream category (may include gaps associated with natural processes) B Degraded (example: scattered trees) C Stream shading is gone or largely absent 19. Buffer Width – streamside area metric (skip for Tidal Marsh Streams) Consider “vegetated buffer” and “wooded buffer” separately for left bank (LB) and right bank (RB) starting at the top of bank out to the first break. Vegetated Wooded LB RB LB RB A A A A ≥ 100 feet wide or extends to the edge of the watershed B B B B From 50 to < 100 feet wide C C C C From 30 to < 50 feet wide D D D D From 10 to < 30 feet wide E E E E < 10 feet wide or no trees 20. Buffer Structure – streamside area metric (skip for Tidal Marsh Streams) Consider for left bank (LB) and right bank (RB) for Metric 19 (“Vegetated” Buffer Width). LB RB A A Mature forest B B Non-mature woody vegetation or modified vegetation structure C C Herbaceous vegetation with or without a strip of trees < 10 feet wide D D Maintained shrubs E E Little or no vegetation 21. Buffer Stressors – streamside area metric (skip for Tidal Marsh Streams) Check all appropriate boxes for left bank (LB) and right bank (RB). Indicate if listed stressor abuts stream (Abuts), does not abut but is within 30 feet of stream (< 30 feet), or is between 30 to 50 feet of stream (30-50 feet). If none of the following stressors occurs on either bank, check here and skip to Metric 22: Abuts < 30 feet 30-50 feet LB RB LB RB LB RB A A A A A A Row crops B B B B B B Maintained turf C C C C C C Pasture (no livestock)/commercial horticulture D D D D D D Pasture (active livestock use) 22. Stem Density – streamside area metric (skip for Tidal Marsh Streams) Consider for left bank (LB) and right bank (RB) for Metric 19 (“Wooded” Buffer Width). LB RB A A Medium to high stem density B B Low stem density C C No wooded riparian buffer or predominantly herbaceous species or bare ground 23. Continuity of Vegetated Buffer – streamside area metric (skip for Tidal Marsh Streams) Consider whether vegetated buffer is continuous along stream (parallel). Breaks are areas lacking vegetation > 10 feet wide. LB RB A A The total length of buffer breaks is < 25 percent. B B The total length of buffer breaks is between 25 and 50 percent. C C The total length of buffer breaks is > 50 percent. 24. Vegetative Composition – streamside area metric (skip for Tidal Marsh Streams) Evaluate the dominant vegetation within 100 feet of each bank or to the edge of the watershed (whichever comes first) as it contribute s to assessment reach habitat. LB RB A A Vegetation is close to undisturbed in species present and their proportions. Lower strata composed of native species, with non-native invasive species absent or sparse. B B Vegetation indicates disturbance in terms of species diversity or proportions, but is still largely composed of native species. This may include communities of weedy native species that develop after clear -cutting or clearing or communities with non-native invasive species present, but not dominant, over a large portion of the expected strata or communities missing understory but retaining canopy trees. C C Vegetation is severely disturbed in terms of species diversity or proportions. Mature canopy is absent or communities with non-native invasive species dominant over a large portion of expected strata or communities composed of planted stands of non-characteristic species or communities inappropriately composed of a single species or no vegetation. 25. Conductivity – assessment reach metric (skip for all Coastal Plain streams) 25a. Yes No Was conductivity measurement recorded? If No, select one of the following reasons. No Water Other: 25b. Check the box corresponding to the conductivity measurement (units of microsiemens per centimeter).
