INVASIVE SPECIES TREATMENT LOGS 2017 Year 2 Monitoring Report (Contract No. 5791) Table of Contents page i Aycock Springs Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina 1.0 EXECUTIVE SUMMARY Monitoring Year 2 (2017), of the Aycock Springs Stream and Wetland Mitigation Site (Site), showed a continued trend towards long-term stability and success of the project. In October of 2017, the NC IRT released Yr. 1 monitoring credits as proposed without condition. Year 2 (2017) stem count measurements were performed on July 25, 2017, and showed a Site average of 379 planted stems per acre (excluding livestakes) and 494 stems per acre when including natural recruits but excluding livestakes. Twelve of the fourteen individual vegetation plots met success criteria based on planted stems alone. When including naturally recruited stems of box elder (Acer negundo) and elm (Ulmus sp.), plot 13 was above success criteria. Five additional temporary 50 -meter by 2 -meter or 25 -meter by 4 -meter vegetation survey transects were established in 2017 in areas of replanting. Stem counts were performed in April and again in October, with October results reporting an average density of 477 stems per acre. Bare root planting conducted after construction continues to struggle in areas where remedial planting occurred. However, monitoring efforts, do indicate the remedial planting has been successful. RS is not proposing additional replanting or remedial action for vegetation at this time but will continue to use random linear vegetation plots to help assist in vegetation monitoring efforts. Axiom Environmental performed Year 2 (2017) stream measurements on April 191 and 20th. As a whole, monitoring measurements indicate minimal changes in the cross-sections as compared to Yr. 1 (2016) data. The channel geometry compares favorably with the proposed conditions as outlined in the detailed mitigation plan and as constructed. Immediately after construction and before ground cover established, multiple heavy rain events (2+ inches) caused some sedimentation in the streambed. This aggradation can be seen in several of the UT -1 and UT - 2 cross-sections and noted during the 2016 monitoring year review. Both visual and physical monitoring of the reaches did not indicate further issues, sediment transport appears to have naturalized, and adjacent riparian areas have stabilized. The above-mentioned rain events were also responsible for moderate bed erosion of two rifles, approximately 30 feet in length near UT -1 cross-section 9. Streambed erosion was noted shortly after as - built measurements were taken. RS created and implemented a remedial action plan during late winter of 2016/2017 (see Section 3.0). These repairs appeared stable during Year 2 (2017) monitoring and will continue to be monitored during subsequent monitoring years as will sediment transport within the UT -1 and UT -2. All in -stream structures are intact and functioning as designed and no stream areas of concern were identified during Year 2 (2017) monitoring. As part of the stream morphology analysis (Table 12a -f, Appendix D), bank height ratios were calculated for each cross-section. This value shows the extent of aggradation and/or down -cutting in the streambed. Several cross-sections exhibited small variation in bank height ratio during Year 2 (2017). Results are summarized and discussed in Section 3.0 of this report and further detailed on the specific cross-section details located in Appendix D. During the fall/winter, monthly visual monitoring efforts revealed the establishment of a beaver dam within the Enhancement -II reach of Travis Creek, between the outfalls of UT -3 and 4. RS is working with the landowner on trapping resident beaver over the winter of 2017/2018 and will physically remove the dam just before the 2018 growing season. No issues with cattle intrusion or fence failure were observed during Yr. 2 monitoring efforts. 2017 Year 2 Monitoring Report (Contract No. 5791) page I Aycock Springs Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina 2.0 PROJECT SUMMARY The Aycock Springs Stream and Wetland Mitigation Site (Site) encompasses approximately 13 acres located roughly 1.5 miles north of Elon and Gibsonville in western Alamance County within 14 -digit Cataloging Unit and Targeted Local Watershed 03030002030010 of the Cape Fear River Basin (Figure 1, Appendix B and Table 4, Appendix A). Prior to construction, the Site consisted of agricultural land used for livestock grazing, hay production, and timber harvest. Streams were cleared, trampled by livestock, eroded vertically and laterally, and received extensive sediment and nutrient inputs from livestock and timber harvest activities. Stream impacts in Travis Creek also occurred due to a breached dam that impounded water during storm events. In addition, streamside wetlands were drained by channel incision, soil compaction, the loss of forest vegetation, and land uses. Completed project activities, reporting history, completion dates, project contacts, and project attributes are summarized in Tables 1-4 (Appendix A). Positive aspects supporting mitigation activities at the Site include the following. • Streams have a Best Usage Classification of WS -V, NSW • Located in a Targeted Local Watershed and within the NCDMS Travis, Tickle, Little Alamance Local Watershed Planning (LWP) Area • Travis Creek is listed on the NCDENR 2012 303(d) list for ecological/biological integrity • Immediately south and abutting the Site is a property identified in the Little Alamance, Travis, & Tickle Creek Watersheds Restoration Plan (PTCOG 2008) as a target property for wetland restoration and streambank enhancement/conservation • Immediately west of the Site is a large tract associated with Guilford County open space Based on the Cape Fear River Basin Restoration Priorities Report 2009 (NCEEP 2009) and the Little Alamance, Travis, & Tickle Creek Watersheds Restoration Plan (PTCOG 2008), Targeted Local Watershed 03030002030010 is not meeting its designated use of supporting aquatic life. Agricultural land use appears to be the main source of stress in the Hydrologic Unit, as well as land clearing and poor riparian management. This project will meet the eight priority goals of the Travis, Tickle, Little Alamance Local Watershed Plan (LWP) including the following. 1) Reduce sediment loading 2) Reduce nutrient loading 3) Manage stormwater runoff 4) Reduce toxic inputs 5) Provide and improve instream habitat 6) Provide and improve terrestrial habitat 7) Improve stream stability 8) Improve hydrologic function The following six goals were identified by the Stakeholder group of the Travis, Tickle, Little Alamance LWP Phase I assessment which address the water quality impacts and watershed needs in all of the Little Alamance, Travis, Tickle watersheds in 2006. 1) Increase local government awareness of the impacts of urban growth on water resources 2) Strengthen watershed protection standards 3) Improve water quality through stormwater management 4) Identify and rank parcels for retrofits, stream repair, preservation, and/or conservation 5) Assess aquatic health to identify stressors that are the most likely causes of poor biological conditions 6) Meet requirements of outside funding sources for implementation of projects 2017 Year 2 Monitoring Report (Contract No. 5791) page 2 Aycock Springs Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina The following table summarizes the project goals/objectives and proposed functional uplift based on restoration activities and observations of two reference areas located in the vicinity of the Site. Goals and objectives target functional uplift identified in the Travis, Tickle, Little Alamance LWP and based on stream/wetland functional assessments developed by the regulatory agencies. Project Goals and Objectives Project Goal/Objective How Goal/Objective will be Accomplished Improve Hydrology Restore Floodplain Access Building a new channel at the historic floodplain elevation to restore overbank flows Restore Wooded Riparian Buffer Planting a woody riparian buffer Restore Stream Stability Providing proper channel width and depth, stabilizing channel banks, providing gravel/cobble substrate, planting a woody riparian buffer, and removing cattle Improve Sediment Transport to Convert the UTs from Sand/Silt Dominated to Gravel/Cobble Dominated Streams Improve Stream Geomorphology Increase Surface Storage and Retention Building a new channel at the historic floodplain elevation restoring overbank flows, removing cattle, scarifying compacted soils, and planting woody vegetation Restore Appropriate Inundation/Duration Increase Subsurface Storage and Retention Raising the stream bed elevation and rip compacted soils Improve Water Quality Increase Upland Pollutant Filtration Planting a native, woody riparian buffer Increase Thermoregulation Planting a native, woody riparian buffer Reduce Stressors and Sources of Pollution Removing cattle and other agricultural inputs Increase Removal and Retention of Pathogens, Particulates (Sediments), Dissolved Materials (Nutrients), and Toxins from the Water Column Raising the stream bed elevation, restoring overbank flows, planting with woody vegetation, removing cattle, increasing surface storage and retention, and restoring appropriate inundation/duration Increase Energy Dissipation of Overbank/Overland Flows/Stormwater Runoff Raising the stream bed elevation, restoring overbank flows, and planting with woody vegetation Restore Habitat Restore In -stream Habitat Building a stable channel with a cobble/gravel bed and planting a woody riparian buffer Restore Stream -side Habitat Planting a woody riparian buffer Improve Vegetation Composition and Structure Project construction was completed April 6, 2016 and planting was completed April 8, 2016. Site activities included the restoration of perennial and intermittent stream channels, enhancement (Level II) of perennial stream channel, and re-establishment of riparian wetlands. Priority I restoration of intermittent channels at the Site is imperative to provide significant functional uplift to Site hydrology, water quality, and habitat, in addition to restore adjacent streamside, riparian wetlands. A total of 3581.1 Stream Mitigation Units (SMUs) and 0.5 Riparian Wetland Mitigation Units (WMUs) are being provided as depicted in the following table. 2017 Year 2 Monitoring Report (Contract No. 5791) page 3 Aycock Springs Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina * Wetland enhancement acreage is not included in mitigation credit calculations as per RFP 16-005568 requirements. ** Prior to Site selection, the landowner received a violation for unauthorized discharge of fill material into Waters of the United States. Fill resulted from unpermitted upgrades to a farm pond dam, including widening the dam footprint, dredging stream channel, and casting spoil material adjacent to the stream channel on jurisdictional wetlands. Prior to restoration activities the landowner was required to obtain an after -the -fact permit to resolve the violations of Section 301 of the Clean Water Act (Action ID:SAW-2014-00665). In addition, stream reaches and wetland areas associated with the violation have been removed from credit generation. In addition, the landowner received a violation for riparian buffer impacts due to clearing of trees adjacent to streams draining to Jordan Lake (NOV-2013-BV-0001). As a result of this violation, the upper 122 linear feet of UT 3 has a reduced credit ratio (1.5:1). On-site visits conducted with USACE representatives determined that the functional uplift of project restoration to UT 3 would be satisfactory to generate credit at this ratio. Stream Success Criteria Monitoring and success criteria for stream restoration should relate to project goals and objectives. From a mitigation perspective, several of the goals and objectives are assumed to be functionally elevated by restoration activities without direct measurement. Other goals and objectives will be considered successful upon achieving vegetation success criteria. The following summarizes stream success criteria related to goals and objectives.

Subsequently, 290 planted stems per acre must be surviving in year 4, 260 planted stems per acre in year 5, and 210 planted stems per acre in year 7. In addition, planted vegetation must average 10 feet in height in each plot at year 7 since this Site is located in the Piedmont. Volunteer stems may be considered on a case- by-case basis in determining overall vegetation success; however, volunteer stems should be counted separately from planted stems. Wetland Success Criteria Monitoring and success criteria for wetland re-establishment should relate to project goals and objectives. From a mitigation perspective, several of the goals and objectives are assumed to be functionally elevated by restoration activities without direct measurement. Other goals and objectives will be considered successful upon achieving vegetation success criteria. The following summarizes wetland success criteria related to goals and objectives.

Restore Habitat Restore Stream -side Habitat Attaining Vegetation Success Criteria. Improve Vegetation Composition and Structure According to the Soil Survey of Alamance County, the growing season for Alamance County is from April 17 — October 22 (USDA 1960). However, the start date for the growing season is not typical for the Piedmont region; therefore, for purposes of this project gauge hydrologic success will be determined using data from February 1 - October 22 to more accurately represent the period of biological activity. This will be confirmed annually by soil temperatures and/or bud burst. The growing season will be initiated each year on the documented date of biological activity. Photographic evidence of bud burst and field logs of date and temperature will be included in the annual monitoring reports. Target hydrological characteristics include saturation or inundation for 10 percent of the monitored period (February 1 -October 22), during average climatic conditions. During years with atypical climatic conditions, groundwater gauges in reference wetlands may dictate threshold hydrology success criteria (75 percent of reference). These areas are expected to support hydrophytic vegetation. If wetland parameters are marginal as indicated by vegetation and/or hydrology monitoring, a jurisdictional determination will be performed.

Summary information/data related to the occurrence of items such as beaver or encroachment and statistics related to performance of various project and monitoring elements can be found in tables and figures within this report's appendices. Narrative background and supporting information formerly found in these reports can be found in the Baseline Monitoring Report (formerly Mitigation Plan) and in the Mitigation Plan (formerly the Restoration Plan) documents available on the NC Division of Mitigation Services (NCDMS) website. All raw data supporting the tables and figures in the appendices are available from NCDMS upon request. 2017 Year 2 Monitoring Report (Contract No. 5791) page 6 Aycock Springs Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina 3.0 METHODOLOGY Monitoring requirements and success criteria outlined in the US Army Corps of Engineers (USACE) April 2003 guidance (Stream Mitigation Guidelines) will be followed and are briefly outlined below. Monitoring data collected at the Site should include reference photos, plant survival analysis, channel stability analysis, and biological data, if specifically required by permit conditions. Wetland hydrology is proposed to be monitored for a period of seven years (years 1-7). Riparian vegetation and stream morphology is proposed to be monitored for a period of seven years with measurements completed in years 1-3, year 5, and year 7. Monitoring reports for years 4 and 6 will include photo documentation of stream stability and wetland hydrology monitoring data. If monitoring demonstrates the Site is successful by year 5 and no concerns have been identified, Restoration Systems (RS) may propose to terminate monitoring at the Site and forego monitoring requirements for years 6 and 7. Early closure will only be provided through written approval from the USACE in consultation with the Interagency Review Team (NC IRT). Monitoring will be conducted by Axiom Environmental, Inc (AXE). Annual monitoring reports of the data collected will be submitted to the NCDMS by RS no later than December 31 of each monitoring year data is collected. 3.1 Streams Annual monitoring will include development of channel cross-sections and substrate on riffles and pools. Data to be presented in graphic and tabular format will include 1) cross-sectional area, 2) bankfull width, 3) average depth, 4) maximum depth, 5) width -to -depth ratio, 6) bank height ratio, and 7) entrenchment ratio. Longitudinal profiles will not be measured routinely unless monitoring demonstrates channel bank or bed instability, in which case, longitudinal profiles may be required by the USACE along reaches of concern to track changes and demonstrate stability. Visual assessment of in -stream structures will be conducted to determine if failure has occurred. Failure of a structure may be indicated by collapse of the structure, undermining of the structure, abandonment of the channel around the structure, and/or stream flow beneath the structure. In addition, visual assessments of the entire channel will be conducted in years 1-3, 5, and 7 of monitoring as outlined in NCDMS Monitoring Requirements and Reporting Standards for Stream and/or Wetland Mitigation. Areas of concern will be depicted on a plan view figure identifying the location of concern along with a written assessment and photograph of the area. Year 2 (2017) Stream measurements were performed April 19-20. As a whole, monitoring measurements indicate minimal changes in the cross-sections as compared to as -built and Year 1 data. The channel geometry compares favorably with the proposed conditions as set forth in the detailed mitigation plan and as constructed. Immediately after construction and before ground cover established, multiple heavy rain events (2+ inches) caused some sedimentation in the streambed. This aggradation can be seen in several of the UT -1 and UT - 2 cross-sections and noted during the 2016 monitoring year review. Both visual and physical monitoring of the reaches did not indicate further issues, sediment transport appears to have naturalized, and adjacent riparian areas have stabilized. The above-mentioned rain events were also responsible for moderate bed erosion of two rifles, approximately 30 feet in length near UT -1 cross-section 9. Streambed erosion was noted shortly after as - built measurements were taken. RS created and implemented a remedial action plan during late winter of 2016/2017 (see Section 3.0). These repairs appeared stable during Year 2 (2017) monitoring and will continue to be monitored during subsequent monitoring years as will sediment transport within the UT -1 and UT -2. 2017 Year 2 Monitoring Report (Contract No. 5791) page 7 Aycock Springs Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina As part of the stream morphology analysis (Table 12a -f, Appendix D), bank height ratios were calculated for each cross-section. This value shows the extent of aggradation and/or down -cutting in the streambed. Several cross-sections exhibited small variation in bank height ratio during Year 2 (2017). These are summarized and discussed in the table below: XS # Reach BHR Notes 2 Travis Cr 1.04 4 Travis Cr 1.04 5 Travis Cr Sediment deposition in pool appears natural and is not expected to lead to instability. 7 Travis Cr Sediment deposition in pool appears natural and is not expected to lead to instability. 11 Travis Cr 1.06 12 Travis Cr 1.03 13 Travis Cr Sediment deposition in pool appears natural and is not expected to lead to instability. 8 and 9 UT 1 Cross sections 8 and 9 (UT 1) are located in the vicinity of a bed material repair. Additional bed material was added by hand in this reach. 13 UT 1 Point bar development appears stable after years 1 and 2 monitoring. Sediment transport appears to be natural and has stabilized during years 1 16 UT 1 and 2 monitoring. No problems appears to be occurring in this reach. No problems have been noted in this reach. Elevated BHR results from 17 UT 1 1.14 shallow channel depth. No problems have been noted in this reach. Elevated BHR results from 18 UT 1 1.33 shallow channel depth. 19 UT 3 Point bar development appears stable after years 1 and 2 monitoring. 21 UT 4 Point bar development appears stable after years 1 and 2 monitoring. 23 UT 5 1.17 No problems have been noted in this reach. Elevated BHR results from shallow channel depth. Across the site, all in -stream structures are intact and functioning as designed. No stream areas of concern were identified during Year 2 (2017) monitoring. Tables for annual quantitative assessments are included in Appendix D. 3.2 Vegetation After planting was completed on April 8, 2016, an initial evaluation was performed to verify planting methods and to determine initial species composition and density. For quantitative vegetation sampling, 14 sample plots (10 -meter by 10 -meter) were installed within the Site per guidelines established in CVS-EEP Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008). In each sample plot, vegetation parameters to be monitored include species composition and species density. Visual observations of the percent cover of shrub and herbaceous species will also be documented by photograph. Year 2 (2017) stem count measurements were performed on July 25, 2017 and indicate an average of 379 planted stems per acre (excluding livestakes) across the Site; therefore, the Site is meeting vegetation success criteria. Twelve of the fourteen individual vegetation plots met success criteria based on planted stems alone. When including naturally recruited stems of box elder (Acer negundo) and elm (Ulmus sp.), plot 13 was above success criteria. Year 2 (2017) vegetation plot information can be found in Appendix C. 2017 Year 2 Monitoring Report (Contract No. 5791) page 8 Aycock Springs Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina Year 1 (2016) vegetation data showed clearly that bare root planting did not take well and success criteria were not being met. In a proactive approach, RS worked with Carolina Silvics, on developing a remedial action plan in the late fall of 2016. During the week of December 20th, 2016, RS implemented that plan by planting 1,030 containerized trees, consisting of 755 1 -gallon pots and 275 3 -gallon pots. Specific species planted included the following: Betula nigra, Fraxinus pennsylvanica, Platanus occiendentalis, Quercus falcata, Quercus nigra, Quercus palustris, Quercus phellos, and Quercus rubra. The remedial planting plan report detailing location of planting and density is provided in Appendix G. Five additional temporary 50 -meter by 2 -meter or 25 -meter by 4 -meter vegetation survey transects were established in 2017 in areas of replanting. Stem counts were performed in April and again in October, with October results reporting an average density of 477 stems per acre. Bare root planting conducted after construction continues to struggle in areas where remedial planting occurred. However, monitoring efforts, do indicate the remedial planting has been successful. RS is not proposing additional replanting or remedial action for vegetation at this time but will continue to use random linear vegetation plots to help assist in vegetation monitoring efforts. 3.3 Wetland Hydrology Three groundwater monitoring gauges were installed to take measurements after hydrological modifications were performed at the Site. Hydrological sampling will continue throughout the growing season at intervals necessary to satisfy jurisdictional hydrology success criteria (USEPA 1990). A surface water gauge has been installed in Tributary 3 to monitor flow regime of the tributary. Approximate locations of gauges are depicted on Figure 2 (Appendix A). An on-site rain gauge will document rainfall data for comparison of groundwater conditions with extended drought conditions and floodplain crest gauges will confirm overbank flooding events. All groundwater gauges were successful in year 2 (2017) (Appendix E). 3.4 Biotic Community Change Changes in the biotic community are anticipated from a shift in habitat opportunities as tributaries are restored. In -stream, biological monitoring is proposed to track the changes during the monitoring period. The benthic macroinvertebrate community will be sampled using NCDWQ protocols found in the Standard Operating Procedures for Benthic Macroinvertebrates (NCDWQ 2006) and Benthic Macroinvertebrate Protocols for Compensatory Stream Restoration Projects (NCDWQ 2001). Biological sampling of benthic macroinvertebrates will be used to compare preconstruction baseline data with postconstruction restored conditions. Two benthic macroinvertebrate monitoring locations will be established within restoration reaches. Postrestoration collections will occur in the approximate location of the prerestoration sampling. Benthic macroinvertebrate samples will be collected from individual reaches using the Qual-4 collection method. Sampling techniques of the Qual-4 collection method consist of kick nets, sweep nets, leaf packs, and visual searches. Preproject biological sampling occurred on June 26, 2014; postproject monitoring will occur in June of monitoring years 2-5. Identification of collected organisms will be performed by personnel with North Carolina Division of Water Resources (NCDWR) or by a NCDWR certified laboratory. Other data collected will include D50 values/NCDWR habitat assessment forms. Biological sampling for year 3 (2017) occurred on June 15, 2017. The samples were sent to Pennington and Associates, a NCDWR certified laboratory, for identification and analysis. The results and Habitat Assessment Dataforms are included in Appendix F. 2017 Year 2 Monitoring Report (Contract No. 5791) page 9 Aycock Springs Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina 4.0 REMEDIAL ACTION PLAN A remedial action plan was developed in order to address stream and vegetation problem areas observed during Year 1 (2016) monitoring. 20107 monitoring efforts of the remedial actions yielded favorable results. Vegetation establishment is treading towards meeting Year 7 success criteria and sediment transport appears to have naturalized across the Site. The completed remedial action report can be found in Appendix G. 4.1 Stream The observed degradation in and adjacent to cross-sections 9 and 10 on UT -1 encompasses approximately 12 linear feet and 15 linear feet of stream, respectively (<1 percent of the project length). As noted above, bed material placed during construction was too fine. All of UT -1 used bed material harvested on-site. The material used along these stream reaches was too fine and washed from the riffles during heavy rainfall events, resulting in minor bed scour and a small, less than 6 inch head cut beginning to develop at the top of riffle. Suitable sized channel bed material was installed on February 23, 2017 at the proper elevation in the two riffles within UT -1. Bed material was installed such that bank toe protection is provided and planting with willow stakes will occur. Bank toe protection designates that channel bed material will extend up the lower one-third of the bank. The riffle will be monitored by established cross-sections 9 and 10. 4.2 Vegetation Multiple factors are contributing to poor vegetative success; a later than desired initial bare -root planting, heavy herbaceous competition primarily from fescue (Site was previously a cattle pasture), and sporadic rain events, which left upland areas of the site dry for extended periods of the growing season. On site observations do indicate a greater survival of planted species within riparian areas. Upland areas of the site are where survival rates were low. The remedial action plan supplemented the bare -root planting over 5.44 acres with 1030 additional trees (755 1 -gallon pots and 275 3 -gallon pots). The remedial action plan figure (Appendix G) details the areas that received remedial planting along with density and number of species being placed into vegetation plots. Working with Carolina Silvics, RS acquired and re -planted identified areas during the week of December 20', 2016. Species of planted tree included Betula nigra, Fraxinus pennsylvanica, Platanus occiendentalis, Quercus falcata, Quercus nigra, Quercus palustris, Quercus phellos, and Quercus rubra. It should be noted that vegetation plot 13 is located within an existing wooded area and has a number of large natural recruit species (box elder and American elm). 5.0 REFERENCES Environmental Laboratory. 1987.

For example, even modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control, t potentially large coverages of Microstegium in the herb layer will not Ilkley trigger control because of the limited capacities to impact tree/shrub layers within the timeframes discussed and the potential impacts of treating extensive amounts ground cover.

The segment which is assessed should represent average stream conditions. To perform a proper habitat evaluation the observer needs to get into the stream. To complete the form, select the description which best fits the observed habitats and then circle the score. If the observed habitat falls in between two descriptions, select an intermediate score. A final habitat score is determined by adding the results from the different metrics. trc, �iJ ], t Stream X 4- `T't-.,J:', Cfttt Location/road: G '.'�r (I oad Name )County %`�ww�a✓'F Date ��S!
