RESTORATION PROJECT GOALS AND OBJECTIVES EEP develops River Basin Restoration Priorities to guide its restoration activities within each of the state's 54 cataloging units. RBRPs delineate specific watersheds that exhibit both the need and opportunity for wetland, stream and riparian buffer restoration. These watersheds are called Targeted Local Watersheds (TLWs) and receive priority for EEP planning and restoration project funds. The 2010 Tar - Pamlico River Basin Restoration Priorities identified the Chocowinity Creek Watershed (HUC: 03020104010010) as a Targeted Local Watershed (Tar - Pamlico River Basin Restoration Priorities, Oct 2010). The watershed is characterized by 41% agricultural and 53% forested area with 59% of the TLW unbuffered and receiving excess agricultural inputs (sediments and nutrients) from various facilities such as four (4) permitted hog farms. The 2010 Tar - Pamlico River Basin RBRP identified discontinuity of resource lands to Natural Heritage Areas and nutrient and sediment loading as major stressors within this TLW. The Hudson Property Project was identified as a headwater stream and buffer restoration opportunity to improve water quality, terrestrial wildlife and anadromous fish habitat, especially downstream nursery and spawning habitats within the TLW. The primary objectives of this project are to restore naturally functioning headwater stream system across a newly forested floodplain in the lower reaches of the project area, and to restore stable single thread channels in the upper reaches where valley slopes are steeper. The project goals address stressors identified in the TLW and include the following: Goals outlined by the EEP in the "Tar- Pamlico River Basin Restoration Priorities ": • Promoting nutrient and sediment reduction in agricultural areas by restoring and preserving wetlands, streams and riparian buffers. • Continuing targeted implementation of projects under the Nutrient Offset and Buffer programs, as well as focusing DOT sponsored restoration in areas where they will provide the most functional improvement to the ecosystem. Goals specific to the Chocowinity Creek TLW: • Implementing agricultural Best Management Practices (BMPs) to reduce nonpoint source inputs to the downstream estuary. • Restore /improve downstream nursery ad spawning habitats for anadromous fish. • Restore wildlife habitat and travel corridors between natural habitats. • Restore natural floodplain hydrology and provide flood attenuation. • Restore groundwater and surface water hydrology in heavily ditched headwater areas. Protect Specific Goals: • Improve and sustain hydrologic connectivity /interaction and storm flow /flood attenuation. • Reduce nutrient and sediment stressors to the reach and receiving watershed. • Provide uplift in water quality functions. 1 NCEEP Mitigation Template version 2.2 — 0610812012 • Improve aquatic and terrestrial habitats (complexity, quality). • Improve and maintain riparian buffer habitat. The project goals will be addressed through the following project obiectives: • Implement a sustainable, reference - based, rehabilitation of the reach dimension, pattern, and profile to provide needed capacity and competency. • Support the removal of barriers to anadromous fish movement and to help improve nursery and spawning habitats. • Strategically install stream structures and plantings designed to maintain vertical and lateral stability and improve habitat diversity /complexity. • Provide a sustainable and functional bankfull floodplain feature. • Enhance and maintain hydrologic connection between stream and adjacent floodplain /riparian corridors. • Utilize the additional width of the swamp runs to provide natural filters for sediment and nutrients and diffuse flow from upstream runoff. • Install, augment, and maintain appropriate riparian buffer with sufficient density and robustness to support native forest succession. • Water quality enhancement through riparian forest planting and woody material installation, and increased floodplain interaction /overbank flooding. • Restore the existing ditched streams to single and multi- thread headwater systems with forested riparian buffers. • Provide ecologically sound construction techniques that will require minimal grading and disturbance. 2. SITE SELECTION 2.1 Directions to Site The project, Hudson Site, consists of 13.4 acres positioned on 106.51 acres of agricultural land owned by Charles E. Hudson. The project located within the northeast quadrant of the intersection between Route 17 and Route 1127 (Possum Track Road) in Beaufort County, NC. More specifically, the project lies approximately 6 miles southeast of the Chocowinity Bay and Pamlico River confluence, 4.3 miles south of the town of Chocowinity, and 4.4 miles north of the Beaufort and Craven County line. The site can be accessed by heading west on Possum Track Road (Rt. 1127) from Route 17 for approximately 1.1 miles (Exhibit A). 2.2 Site Selection The site was chosen for various reasons including but not limited to: headwater location within the Chocowinity Creek TLW, proximity to the 303d listed Chocowinity Bay, and the excellent opportunity available to restore and re- connect riparian headwater stream and swamp run systems with existing forest stands immediately adjacent to the project area. The site contains unnamed 1st, 2nd, and 3rd order tributaries with an upstream drainage area of approximately 190 acres that drain to Horse Branch 2 NCEEP Mitigation Template version 2.2 — 0610812012 which is located within the Chocowinity Creek TLW (see Exhibit B and H). Historic aerial photographs show evidence of the natural headwater streams that were cleared for agriculture production. The majority of the site is used for crop production, primarily corn, soybeans and wheat. As a result, the lowering of local water tables, and in some cases the complete elimination of ground and surface water interaction, has occurred and the degradation of water quality and downstream anadromous fish spawning and nursery habitat have followed. According to the North Carolina Geologic map, the site lies within the Yorktown Formation and Duplin Formations which is a combination of fossiliferous clay and sand, Shelly sand, sandy marl, and limestone. The site contains mostly low gradient non - hydric moderately drained soil types such as Craven fine sandy loam (CrB) and Goldsboro fine sandy loam (GoA) and within the Horse Branch floodplain the Muchalee loam (Me) hydric soil type is present (Exhibit Q. Hydric soils are seen in the stream bank profile which shows the opportunity to raise the water table and re- establish normal base flow conditions. Historic aerial photographs from the years 1938, 1963, and 1979 show the extensive drainage network leading from southeast to northwest (Exhibits E, F, G). Between the years of 1938 to 1963, extensive forest clearing and agricultural production occurred on the site, especially on the northwest portion of the site where the unnamed 2`d order tributary flows into Horse Branch. From 1938 to 1948, logging in the northeast corner was completed and by 1963, the entire project area was cleared and ditched for agriculture production. North Carolina Division of Water Quality Stream Identification Forms have been completed for the degraded headwater streams and are found in Appendix B. The project site and watershed conditions such as land use have remained relatively static with continued maintenance of agricultural land since 1979 (Exhibits B and 1). This trajectory will remain the same with no proposed development trends within the project's watershed. There are no known site constraints such as existing easements or crossings that would inhibit site access and /or completion of the project. Small farm road crossings /culverts present on both the upstream and downstream portions of the site will be removed as part of the restoration, and new culvert crossings will be installed at the confluence of Reach 1 and Reach 4, upper limit of Reach 5 to provide long term access to the mitigation site. An access road under the existing power line right -of- way along Possum Track Road will also be installed to serve as the main access point into the mitigation site. 3.

CREDIT RELEASE SCHEDULE All credit releases will be based on the total credit generated as reported by the as -built survey of the mitigation site. Under no circumstances shall any mitigation project be debited until the necessary DA authorization has been received for its construction or the District Engineer (DE) has otherwise provided written approval for the project in the case where no DA authorization is required for construction of the mitigation project. The DE, in consultation with the Interagency Review Team (IRT), will determine if performance standards have been satisfied sufficiently to meet the requirements of the release schedules below. In cases where some performance standards have not been met, credits may still be released depending on the specifics of the case. Monitoring may be required to restart or be extended, depending on the extent to which the site fails to meet the specified performance standard. The release of project credits will be subject to the criteria described in Table 4 below. Stream Credits Monitoring Credit Release Activity Interim Total Year Release Released 0 Initial allocation — see requirements below 30% 30% 1 First year monitoring report demonstrates performance standards are being met 10% 40% 2 Second year monitoring report demonstrates performance standards are being met 10% 50% (60 % *) 3 Third year monitoring report demonstrates performance standards are being met 10% 60% (70 % *) 4 Fourth year monitoring report demonstrates performance standards are being met 5% 65% (75%*) 5 Fifth year monitoring report demonstrates performance standards are being met 10% 75% (85 % *) 6 Sixth year monitoring report demonstrates performance standards are being met 5% 80% (90 % *) 7 Seventh year monitoring report demonstrates performance standards are being 10% 90% met and project has received closeout approval (100 % *) Table 4. Proposed credit release schedule. 6.1 Initial Allocation of Released Credits The initial allocation of released credits, as specified in the mitigation plan can be released by the NCEEP without prior written approval of the DE upon satisfactory completion of the following activities: a. Approval of the final Mitigation Plan b. Recordation of the preservation mechanism, as well as a title opinion acceptable to the USACE covering the property c. Completion of project construction (the initial physical and biological improvements to the mitigation site) pursuant to the mitigation plan; Per the NCEEP Instrument, construction means that a mitigation site has been constructed in its entirety, to include planting, and an as -built 7 NCEEP Mitigation Template version 2.2 — 0610812012 report has been produced. As -built reports must be sealed by an engineer prior to project closeout, if appropriate but not prior to the initial allocation of released credits. d. Receipt of necessary DA permit authorization or written DA approval for projects where DA permit issuance is not required. 6.2 Subsequent Credit Releases All subsequent credit releases must be approved by the DE, in consultation with the IRT, based on a determination that required performance standards have been achieved. For stream projects a reserve of 15% of a site's total stream credits shall be released after two bank -full events have occurred, in separate years, provided the channel is stable and all other performance standards are met. In the event that less than two bank -full events occur during the monitoring period, release of these reserve credits shall be at the discretion of the IRT. As projects approach milestones associated with credit release, the NCEEP will submit a request for credit release to the DE along with documentation substantiating achievement of criteria required for release to occur. This documentation will be included with the annual monitoring report. 7. MITIGATION WORK PLAN 7.1 Target Stream Type(s) and Plant Communities As stated within both the Site selection (Section 2.2) and Baseline data table (Section 4), the existing channelized reaches are classified as G5 -G6 stream types. The channel evolution model is not applicable in this setting because the ditches continue to be maintained and channelized therefore the evolutionary trend is not able to move forward. The existing ditches are entrenched with low width - depth ratios and do not have active floodplains available. The target stream types for Reaches 1 through 4 are low sinuosity "C" channels. The invert of reach 1 will be raised to reconnect to the existing floodplain elevation (Priority 1 restoration). Restoration of reaches 2, 3 and 4 will involve raising the channel invert where possible and grading a functional floodplain that ties into the existing grade to mimic natural conditions (Priority 1/2 restoration) to ensure positive flow within the reach and from upslope areas. Reach 5 target stream type is a "D" channel with a high width -depth ratio and increased channel capacity due to the reach's close proximity to the Horse Branch Swamp. To achieve these target stream types, reference reach data collected from an unnamed tributary to Bennett's Creek located in Merchant's Millpond State Park within the Chowan River Basin was used as a guide in the design process (see Exhibit J for reference reach location). Both the project and reference sites are located within the Outer Coastal Plain physiographic province. The riparian plant communities chosen for the project are native to the area, with an emphasis on species that will provide habitat and a viable, yearlong food source for a wide range of animal and plant species. The adjacent forested wetlands and swamps within Horse Branch and Chocowinity Creek are home to wild turkeys, bear, whitetail deer, raccoon, squirrel, fox, migrating waterfowl, and a wide variety of amphibian and reptile species. The project is intended to provide food, habitat, and corridors to complement and enhance the existing ecosystem. Invasive and exotic species will not be planted on 8 NCEEP Mitigation Template version 2.2 — 0610812012 the site and if found, they will be removed through physical or chemical means during the planting phase. In selecting vegetation, we have considered reference riparian areas adjacent to the site and "Dominant Plants for Major Wetland Types" published by the North Carolina Department of Environment Water Quality Section. 7.2 Design Methodology In order to properly restore the degraded channels within the project area, the overall design goal is to convert the channelized reaches to more stable stream types. Because of the low entrenchment and width /depth ratios of the existing reach cross sections, reconfiguring the dimension, pattern, and profile of the channels are the most effective method of restoring a stable system. The project will create channels connected to the floodplain and the project area has been broken into five distinct reaches based on drainage area and landscape position. For reaches 1 through 4, a single thread low sinuosity "C" or "Bc" channel type was selected to provide a higher width -depth ratio and increased floodplain connection. After evaluating historic conditions (specifically the 1938 aerial), discussion with the IRT, and taking into account the slightly higher channel and valley slopes within this area, a single thread design channel was chosen. A headwater system /multi- thread "D" type channel has been chosen for Reach 5 to mimic the diffuse flow patterns and dense vegetation seen in undisturbed areas of Horse Branch. Parameters for the proposed channel morphology are based upon the design stream type, historical conditions evident from mid 1900's aerial photography and data from the Millpond State park reference reach surveyed by Ecotone, Inc. Dimensionless ratios taken from the reference reach with dissimilar drainage areas allowed channel morphology data from the reference reaches to be used for this project. 7.3 Reference Reach Natural channel design protocol calls for using a reference reach located in the same physiographic province as the reference site. The Merchant's Millpond site was chosen because it is located in the Inner Coastal Plain physiographic province as well as the Mid - Atlantic Coastal Plain ecoregion. It contains undisturbed first and second order tributaries in a similar landscape position to those found on the project site. Because much of the inner coastal plain has been developed for agricultural production, undisturbed reference sites are rare. The Merchant's Millpond State Park site offers an excellent opportunity to survey streams in an almost completely undisturbed condition. This reference reach surveyed contained both low gradient (<1 %) single and multi- thread sections typical of low gradient and headwater system streams within the coastal plain region of North Carolina. The photo exhibit found in Appendix E show typical conditions encountered at the reference site. Wolman pebble counts were attempted at the reference site and all mineral material collected was smaller than 2 millimeters, further validating the reference reach as a low energy sand bed system. Visual inspection of the project site, combined with soil survey data and anecdotal information from the landowner indicate that the soils on site are sand and loam. Native subsoil will form the bed and banks of the proposed channel, similar to the conditions seen at the reference site. It should also be noted that the reference site contained naturally occurring woody debris impregnated sand riffles, which will be utilized on the project site. Photos of these riffles are found in the Appendix E photo exhibit. 9 NCEEP Mitigation Template version 2.2 — 0610812012 7.4 Design Parameters TR -55 was run for each reach, and the two year flow (Q) was chosen as the basis for the design See section 7.3 below for a detailed explanation of the derivation of hydrology for the site. Reaches 1 through 4 will be designed to'hold the 2 -year TR =55 flow and allow higher flows to escape the channel and spread into an area similar to the historic floodplain to provide greater sediment and pollutant attenuation Near bank stress and erosion will be reduced by lowering the current flow velocities and sizing the channels to have minimal,shear stress Riffles and pools,wilI be constructed according to reference reach ratios derived from the Merchant's Millpond State Park reference reach site. Stable riffle slopes and pool depths will be utilized to accommodate high flow events and the movement of sediments. Riffle slopes will vary from 1 to 2 percent in reaches 1 though 4 where the low sinuosity C5 -C6 channels are proposed. Pool depths will vary from 0.35 feet to, 0.75 feet throughout the restoration with the deeper pools placed in sections where riffle slopes are higher Pool spacing increases as a function of increasing channel width and will vary from 30 to 55 feet. To mimic the riffle -, ,run -pool morphology and the natural condition of low gradient, headwater coastal plain streams, constructed riffles composed of woody material of various sizes embedded into native subsoil material found onsite will be used to provide vertical stability and bed form diversity. These features are naturally occurring in the Mid - Atlantic Coastal Plain ecoregion and form the basis for stability in low gradient sand -based systems Photographs of naturally occurring woody material impregnated riffles can be found in the reference reach information provided with this report The downstream portions of Reaches 1, 3, and 4 will have higher slopes ( +/- 15 - 3 %) to transition from the upstream low energy channels to the existing invert at the downstream end of the project limits These transitional channels will mimic naturally occurring high energy systems, and the log drops are engineered to create conditions similar to those create by large woody debris dams seen in nature: Because natural debris dam dominated systems do not have "typical" spacing`and slope patterns (as they are generally formed by random inputs of large woody material's to the channel), spacing of the log dams selected for this project is fairly standard with elevation changes of less than 0 5 feet at each structure The log cross vanes will be installed within these sections to provide a stable transition and ensure long term vertical stability Reach 5 is designed as a typical headwater system and therefore does not have the typical design parameters associated with traditional natural channel design. This reach will have less bed form diversity due to the,lower slope (<0.4 %) and proximity to the Horse'Branch flood,plain The, headwater system channel geometry with high width ratio and minimal 'sinuosity will provide larger channel capacity and surface area to promote sediment and nutrient trapping and processing as well as hyporheic exchange Reach 5 will be graded such to create diffuse flow patterns and multi- threaded channels Culverts and farm road crossings within Reaches 1 -4 will be removed to complete the proposed channel work A farm road crossing will install at the beginning of Reach 1 and will consist of a 24" HDPE Type S corrugated plastic pipe (CPP) Access road crossings for long term maintenance will be installed at the 10 NCEEP Mitigation Template version,2 2 — 0610812012 upper limit of Reach 5 and at the, confluence of Reaches 1 and A to provide effective stormwater conveyance and a stable long term crossing to access the `northern portions of the remaining property. These crossings will consist of two'30 inch HDPE Type S corrugated CPP's. Proper sizing of,the proposed culverts was completed using the N C Forestry Best Management Practices Manual (2006), specifically Appendix 9 entitled Talbot's Table for Round Culvert Sizing. Sediment transport was not seen as a mayor design consideration for the project because all of the single thread channels are first or second order low energy tributaries found in the upper reaches of the watershed where little sediment supply exists. The intended stream condition will be stable, with little or no movement of non - organic bed "material expected during storm events Woody debris are expected to play a large role in forming and maintaining channel profile features, as the ultimate condition will be channels with low banks and riparian areas densely vegetated with native trees, shrubs and, herbaceous material Woody debris impregnated riffle structures and log cross vanes have been designed, to mimic natural conditions of channels in a similar landscape position, and as the adjacent planted areasimature they'will provide steadysupply of'new woody materials to,the, channel The woody debris impregnated riffles will incorporate a mix of native subsoil materiaLand woody debris that will remain in place during flows above bankfull Traditional entrainment calculations cannot accurately assess potential transport or movement of'woody debris. Studies conducted on large woody debris in streams focus on drag and buoyancy calculations, which do not reliably translate to a woody debris impregnated substrate condition. Because more than two - thirds of the proposed pieces of woody materials used in the riffles will be buried, both buoyancy and drag forces are expected to be negligible The steeper high energy transition areas or reaches 1, 3 ,and 4 will be stabilized using log vanes drop structures. Buoyancy and drag calculations have not been completed for these reaches because more than half of each log will be buried and the crossover- points will be securely anchored with rebar. In addition, backfill behind each structure, 'Will be comprised,of native substrate material and small woody debris, similar to riffle areas Reach 5 is designed to be a swamp run, typical of coastal plain streams These systems' have extremely low or nonexistent sediment transport rates, and the substrate is typically dominated by clay and silt with dense live woody root mass providing stability The reach was not evaluated for entrainment because for the 10 -year storm event, velocities values are less than 2 feet per second and shear stress values are less than 0.23 pounds per square foot By grad'ing the site to create stable stream channels and planting the entire area with woody vegetation and a native wetland seed mix, the project will slow overland runoff and provide storage and water quality treatment before it reaches Horse Branch Stream banks and immediate floodprone areas on 'both sides will be seeded, protected with coir erosion control matting and planted with live stakes. These improvements will also serve to make downstream primary and secondary fishery nursery areas more productive. When completed, each reach segment will be designed to reach " bankfull elevation" and restore historic flow to a degraded riparian headwatersystem. This transition, from degraded stream channels surrounded by agricultural fields, to restored headwater stream /swamp runs; will provide water quality 11 NCEEP Mitigation Template version 2 2 — 0610812012 improvement through sediment, toxicant, and nutrient retention and reduction, production and export of food sources, and enhancement of wildlife habitat 7.5 Narrative of Data Analysis 7.5.1 Hydrology Two delineation methods were used in determining the site's drainage area. The USGS National Hydrology Dataset Watershed Tool served as the primary delineation of the drainage basin which was then field verified and corrected to account for the presence of extensive ditch networks. Using the field verified drainage area of 196 acres, the 2, 10, 50, and 100 year recurrence interval discharges were calculated for each reach using a variety of methods including but not limited to: USDA TR -55 program, North Carolina State University (NCSU) Coastal Plain Regional Curve, and USGS StreamStats Regression equations. After assessing the variety of discharges from the different sources listed above, the design team chose the TR -55 discharges as they best represented the small watershed size of the project and fit in line with the Coastal Plain regional curve discharge estimates (see Table 5 below).

MAINTENANCE PLAN Albemarle Restorations shall monitor the site on a regular basis and shall conduct a physical inspection of the site a minimum of once per year throughout the post- construction monitoring period until performance standards are met. These site inspections may identify site components and features that require routine maintenance. Routine maintenance should be expected most often in the first two years following site construction and may include the following: 12 NCEEP Mitigation Template version 2.2 - 0610812012 Component /Feature Maintenance through project close -out Stream Routine channel maintenance and repair activities may include securing of loose coir matting and supplemental installations of live stakes and other target vegetation along the channel. Areas where stormwater and floodplain flows intercept the channel may also require maintenance to prevent bank failures and head - cutting. Vegetation Vegetation shall be maintained to ensure the health and vigor of the targeted plant community. Routine vegetation maintenance and repair activities may include supplemental planting, pruning, mulching, and fertilizing. Exotic invasive plant species shall be controlled by mechanical and /or chemical methods. Any vegetation control requiring herbicide application will be performed in accordance with NC Department of Agriculture (NCDA) rules and regulations. Site Boundary Site boundaries shall be identified in the field to ensure clear distinction between the mitigation site and adjacent properties. Boundaries may be identified by fence, marker, bollard, post, tree - blazing, or other means as allowed by site conditions and /or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and /or replaced on an as needed basis. Road Crossing Road crossings within the site may be maintained only as allowed by Conservation Easement or existing easement, deed restrictions, rights of way, or corridor agreements. Table 6. Anticipated Maintenance Activities 9. PERFORMANCE STANDARDS 9.1 Stream Restoration Hydrology Performance Standards 9.1.1 Headwater System (Reach 5) Surface water flow must be documented to occur at least 2 times per year for 4 years out of the 7 -year monitoring period during normal rainfall conditions.

At year 7, density must be no less than 210 seven year -old planted stems /acre. 2. Planted vegetation must average 10 feet in height in each plot at year 7 (as defined in the USACE 2003 SMGs). If this performance standard is met by year 5 and stem density is trending toward success (i.e., no less than 260 five year -old stems /acre) monitoring of vegetation on the site may be terminated provided written approval is provided by the USACE in consultation with the North Carolina Interagency Review Team (NCIRT). 10. MONITORING REQUIREMENTS Monitoring Reports will be submitted to EEP by December 1st of the year in which the monitoring was conducted. In the unlikely event that the success criteria are not being achieved during the seven -year 14 NCEEP Mitigation Template version 2.2 — 0610812012 minimum monitoring period, with permission from EEP, corrective measures including re- grading, replacement of structures, replanting, removal of certain species, etc. will be performed. Annual monitoring data will be reported using the EEP monitoring template. The monitoring report shall provide a project data chronology that will facilitate an understanding of project status and trends, population of EEP databases for analysis, research purposes, and assist in decision making regarding project close -out.

Monitoring data requirements. 10.1 General Stream and Wetland Monitoring Requirements 1. Site monitoring for all stream and /or wetland mitigation projects shall occur for seven full years (post construction) except in those circumstances provided for in this document where specific monitoring activities may be terminated as early as five years. If performance standards have not been met by year seven, additional monitoring may be required to ensure that a site is relatively stable with respect to anthropogenic or natural effects and that the target community is established on the site or the site (or portions of the site) may be deemed to be unacceptable for generation of compensatory mitigation credit. 2. Seven years of monitoring are not required for stream and /or wetland preservation reaches or areas which are subject to Monitoring Level 3 requirements of the USACE 2003 SMGs. 15 NCEEP Mitigation Template version 2.2 — 0610812012 3. Success criteria as provided in the mitigation plan or in the permit conditions must be restated verbatim in the monitoring report. 4. Monitoring reports shall be completed for all seven years and provided to the Ecosystem Enhancement Program (EEP) for review by December I" of each year that the site is required to be monitored. This is to ensure that any remedial action that may be necessary can be accomplished during the next planting season. Failure to provide monitoring reports by this deadline may result in additional monitoring. 5. Vegetation monitoring standards shall apply to all stream and /or wetland mitigation projects. 10.2 Stream Channel Surface Water Hydrology Monitoring Requirements (Reach 5) 1. Surface flow shall be documented using pressure transducers with a staff plat and /or and flow meters located near the lowest point of the proposed stream area. 2. Three flow monitoring stations will be located within each reach, one at the upstream limit of the reach, one at the downstream limit and one near the middle of the reach. 3. Other evidence of flow, including rack lines, sediment sorting, debris jams, localized scour and disturbed vegetation will also be visually assessed and documented during monitoring visits. 10.3 Stream Surface Water Hydrology Monitoring Requirements (Reaches 1— 4) 1. Surface water flow shall be documented using pressure transducers and staff plates located near the channel thalweg. 2. Three flow monitoring stations will be located within each reach, one at the upstream limit of the reach, one at the downstream limit and one near the middle of the reach. In areas where one reach is contiguous with another reach, one flow monitoring station will be used to collect data for both reaches where appropriate. 3. Other evidence of flow, including an ordinary high water mark, rack lines, sediment sorting, pool and riffle formation and debris jams will be visually assed and documented during each monitoring visit. 10.4. Stream Channel Stability Monitoring Requirements (Reach 5) 1. Channel areas will be visually assessed to determine if undesirable changes to channel morphology are occurring. 2. If any areas of excessive scour or erosion are seen, those areas will be assessed to determine if remedial measures are necessary or if adaptive management strategies are necessary. 10.5 Stream Channel Stability Monitoring Requirements (Reaches 1— 4) 3. As -built surveys shall be conducted upon completion of channel construction to document baseline conditions. As -built surveys shall include all measurements typically documented during subsequent channel geomorphological surveys. A longitudinal profile of the thalweg, water surface, bankfull, and top of bank, shall also be collected during the as -built survey of the constructed channel to compare with future geomorphological data, if necessary. Longitudinal 16 NCEEP Mitigation Template version 2.2 — 0610812012 profiles shall not be required during routine channel stability monitoring (years 1 through 7) unless the monitoring efforts demonstrate channel bank or bed instability, in which case additional longitudinal profiles may be required by the USACE along channel reaches of concern to track changes in the channel and demonstrate stability. 4. Reference stakes, indicating the surveyed station and corresponding to the as -built survey, shall be installed in the riparian buffer near the stream bank every 100 feet along the length of the stream. 5. Channel cross - sections shall be monitored for 7 years, with monitoring events occurring in years 1, 2, 3, 5, and 7. If the Sponsor /Permittee chooses to conduct supplemental monitoring, results may be considered towards meeting performance standards. 6. Per the USACE 2003 SMGs, permanent, monumented cross - sections shall be installed at a rate of 1 cross - section per 20 bankfull channel widths, with approximately 50% of cross - sections occurring at pools and 50% at riffles /ripples. All channel cross - sections shall include measurements of Bank Height Ratio and Entrenchment Ratio, which shall be documented in monitoring reports. 7. At each monitored cross - section located on a stream bend (typically at pool locations), a bank pin array shall be installed along the outer bend of the stream. Bank pins may consist of chain, rebar, or wire driven horizontally into the bank face, and should be a minimum of 3 feet long. A minimum of one pin per 2 feet of bank height shall be installed vertically at each location, with the lowest pin installed just above the normal water line and additional pins installed at 2 -foot intervals above the first. Vertical series of pins should be installed in at least three locations - at the monumented cross - section, the upstream third of the meander bend, and downstream third of the meander bend. The pins shall be installed flush to the face of the stream bank, and the length of exposed pin shall be measured and reported during each cross - section monitoring event. Once the exposure has been measured, the pin should be hammered flush with the face of the bank. Lateral movement of the stream banks as indicated by pin exposure shall be included in all monitoring reports. Additional bank pin arrays may be required by the USACE to document erosion along particular reaches of channel where concern over channel stability is identified during routine monitoring events. Bank pins are not required on channels with a bankfull width of less than 3 feet, unless indicated by the results of the monitoring or required by the USACE. 10.6 Visual Monitoring Requirements for Single Thread Streams (Reaches 1 - 4) 1. Visual monitoring of all sections of the project shall be conducted in each of the required seven years of monitoring to identify areas of concern in both the vegetated buffer and restored stream channel. The following requirements apply to all stream mitigation projects that are required to comply with Monitoring Levels 1 & 2 in the USACE 2003 SMGs, including all forms of Restoration and Enhancement (Level I and ll). 2. Visual monitoring of all sections of the stream project shall be conducted twice per monitoring year. Generally, one visual monitoring event should be done in conjunction with other stream channel stability monitoring (e.g., cross - sections, bank pins, etc.). At least 5 months shall separate each visual monitoring event. 17 NCEEP Mitigation Template version 2.2 — 0610812012 3. Within the stream channel, visual monitoring shall be conducted along the entire length of the channel to identify and document excessive lateral movement of the channel, bank instability, instability /failure of in- stream structures, structure piping, headcuts, beaver activity, excessive live stake mortality, invasive species, aggradation /excessive sediment deposition, or other potential problems with the channel. Visual monitoring of streams shall be conducted only by individuals that have been properly trained to assess the stability of streams and condition of in- stream structures. 4. Within the vegetated buffer, visual monitoring shall be conducted by walking throughout the entire site to identify and document areas of low stem density or poor plant vigor, invasive species, beaver activity, herbivory, encroachments, indicators of livestock access, or other areas of concern. 5. The results of the visual assessment shall be included in a plan view of the channel identifying the location of each feature of concern, along with a written assessment and photographic documentation of the feature. Once a feature of concern has been identified, that same feature shall be reassessed on all subsequent visual assessments. Photographs should be taken from the same location year -to -year to document progression of the problem. The monitoring reports shall identify all features of concern and recommended courses of action, which may include continued monitoring, repair or other remedial action. 10.7 Vegetation Planting Monitoring Requirements 1. Seven permanent plots to sample vegetation shall be randomly located in each of the target communities. Plot sizes for the determination of stem density and vigor (height) shall be a minimum of 0.02 acre in size, and should typically be square or rectangular. 2. Vegetation monitoring plots shall make up a minimum of 1% of the planted portion of the site with a minimum of 4 plots. 3. Upon initial establishment of vegetation plots (baseline /year 0), the plot corners shall be marked in accordance with CVS Protocol. 4. Within each plot, vegetation data collected will be in accordance with CVS Protocol. 5. Vegetation plots shall be monitored for 7 years, with monitoring events occurring in years 1, 2, 3, 5, and 7. If supplemental monitoring occurs, results may be considered towards meeting performance standards. 6. At least 180 days, occurring between March 1 and November 30, must separate the completion of the initial vegetation planting and the initiation of the first year of monitoring (Year 1). If 180 days has not occurred since the completion of vegetation plantings, the first year of monitoring must occur during the following year. 7. Individual plot data for planted species must be provided. Plot data shall not be averaged over the entire site to obtain a single figure for stem density. 8. Enumeration of the density of planted species: density = number of living, planted stems per acre. "Stems are defined as individual plants, where plants with multiple shoots are treated as a single stem. 9. Live stakes planted on the stream banks shall not count toward meeting the stem density requirements. 18 NCEEP Mitigation Template version 2.2 — 0610812012 10. Volunteer plants growing within plots may be considered on a case -by -case basis in determining whether a project has met the overall goal of reestablishing the vegetated buffer; however, volunteer plants shall be counted separately from planted vegetation in the monitoring reports. Monitoring events should also be used to evaluate the site for the presence of invasive species, which should be noted in the monitoring report. 11. LONG -TERM MANAGEMENT PLAN Upon approval for close -out by the Interagency Review Team (IRT) the site will be transferred to a third party for long term management as described in EEP's In Lieu Fee instrument. This party shall be responsible for periodic inspection of the site to ensure that restrictions required in the conservation easement or the deed restriction document(s) are upheld. Endowment funds required to uphold easement and deed restrictions shall be negotiated prior to site transfer to the responsible party. 12. ADAPTIVE MANAGEMENT PLAN Upon completion of site construction, Albemarle Restorations will implement the post- construction monitoring protocols previously defined in this document. Project maintenance will be performed as described previously in this document. If, during the course of annual monitoring it is determined the site's ability to achieve site performance standards are jeopardized, EEP will notify the USACE of the need to develop a Plan of Corrective Action. The Plan of Corrective Action may be prepared using in- house technical staff or may require engineering and consulting services. Once the Corrective Action Plan is prepared and finalized EEP will: 1. Notify the USACE as required by the Nationwide 27 permit general conditions. 2. Revise performance standards, maintenance requirements, and monitoring requirements as necessary and /or required by the USACE. 3. Obtain other permits as necessary. 4. Implement the Corrective Action Plan. 5. Provide the USACE a Record Drawing of Corrective Actions. This document shall depict the extent and nature of the work performed. 13. FINANCIAL ASSURANCES Pursuant to Section IV H and Appendix III of the Ecosystem Enhancement Program's In -Lieu Fee Instrument dated July 28, 2010, the North Carolina Department of Environment and Natural Resources has provided the U.S. Army Corps of Engineers Wilmington District with a formal commitment to fund projects to satisfy mitigation requirements assumed by EEP. This commitment provides financial assurance for all mitigation projects implemented by the program. 19 NCEEP Mitigation Template version 2.2 — 0610812012 14.

The site is positioned on 15 acres of cropland located on a 106.51 acre farm within the northeast quadrant of the intersection between Route 17 and Route 1127 (Possum Track Road) in Beaufort County, NC. The site is situated approximately 6 miles southeast of the Chocowinity Bay and Pamlico River confluence and 4.4 miles north of the Beaufort and Craven County line. The project contains natural headwater streams that have been extensively ditched and cleared for agricultural production. Historical USDA photos show that the project site has been in continuous crop production since 1938. An updated T &E species list for Beaufort County with habitat analyses for each species based on current on -site conditions is provided below. We thank you in advance for your timely response and cooperation. Please feel free to contact me at (252) 333 -0249 with any questions. Sincerel Edmund R. Temple, Jr. i Principal P.U.

Eels are bottom dwellers and hide in burrows, tubes, snags, masses of plants, other types of shelters They are found in a variety of habitats including streams, rivers, and muddy or silt- bottomed lakes during their freshwater stage, as well as oceanic waters, coastal bays and estuaries. Due to the proposed project's headwater location in the watershed and existing conditions, there is no suitable habitat for this species Therefore, a biological conclusion of "No Effect" has been made Atlantic sturgeon Atlantic sturgeon are anadromous fish that.spawn in freshwater in the spring and early summer and migrate into "estuarine" and marine waters where they spend most of their lives In some southern rivers a fall spawning migration may also occur They spawn in moderately flowing water (46 -76 cm /s) in deep parts of large rivers. Sub - adults and adults live in coastal waters and estuaries when not spawning, generally in shallow (10 -50 m depth) nearshore areas dominated by gravel and sand substrates.Due to the proposed project's headwater location in the watershed and existing conditions, there is no suitable habitat for this species Therefore, a biological conclusion of "No Effect" has been made Bald eagle Bald eagles prefer the open water of lakes, rivers, and marshes for their ,foraging habitat, and tali, mature trees for their nesting and roosting sites The closer these habitats are together, the greater the attraction is for Bald eagles. The project area is currently tilled cropland with several degraded headwater streams (drainage ditches). Based on the habitat requirements and an onsite review, there is no suitable habitat for Bald Eagles within the project area, therefore a biological conclusion of "No Effect" has been made. Black- throated green warbler In southern Virginia and coastal North Carolina, black - throated green warblers are closely associated with Atlantic white cedar. Where cedar is scarce or absent, such as coastal South Carolina, these birds are found iprimanly in non - alluvial forested wetlands or transitional zones between upland and wetland Black- throated green warblers are sometimes found in small or headwater, riparian forests, but most observers suggest an association with forest stand's growing in non - alluvial muck swamp The project area is currently tilled cropland with several' degraded' headwater streams (drainage ditches). Based on the habitat requirements and° an, onsite review, there is no suitable habitat for this species within the project area, therefore a. biological conclusion of "No Effect" has been made Carolina,gopher frog These rare frogs occur at scattered localities in the Sandhills and southeastern Coastal Plain. Little is known about their natural history outside the breeding season. Adults are secretive, spending most of their lives underground. Gopher frogs derive their common name from the fact that adults commonly 'use the burrows of the gopher tortoise (Gopherus polyphemus) as, hiding places in the Deep South, but in North Carolina (whe"re these tortoises do not occur), gopher-frogs hide in stump holes, root tunnels and mammal and crayfish burrows Based on the habitat requirements and an onsite review, there is no suitable ,habitat for this species within the project area, nor is suitable habitat likely to occur once the project is•completed. Eastern.Henslow's sparrow This species occupies ephemeral .grassland habitats. Specific grassland features include unbroken patches of at least 75,acres which are part of larger tracts (at least 400 acres), native grass species like little bluestem, prairie dropseed, blue joint, and Indian grass; few woody plants, substantial litter and old, erect grass stems; and fairly deep weed and grass growth. Periodic burning, light grazing, and controlled mowing produce these iconditions.'Reclaimed strip mines, fallow fields, powerline cuts, and restored prairie can also be used by this sparrow. Winter habitats include coastal ,grasslands, pine savannah, and pitcher plant bogs. The project area is currently tilled cropland with several degraded headwater streams (drainage ditches) Based on the habitat requirements and an onsite review, there is no suitable habitat for this species within the project area, therefore a biological conclusion of "No Effect" has been, made_ Kem_p's (Atlantic) Ridley sea turtle Due to the projects distance from the Atlantic Ocean and Pamlico Sound, and lack of any suitable habitat, a biological conclusion of "No Effect" has been made Rafinesgue's.bie =eared bat This bat has a split range in North Carolina, in the southern Appalachians, and in the sandhills and coastal plain. Natural roost sites include hollow trees and caves, but throughout its range most records of this species are from abandoned buildings Caves and mines are used by this -bat in the upland portions of its range, including North Carolina. In abandoned structures, this bat is found in the darkest portions of the building, preferring windowless rooms such as bathrooms and closets; but in caves, areas receiving some natural light seem preferred Sites along river systems and other permanent bodies of,water nearby old growth forests are preferred Based on the habitat requirements and an onsite review, there is no suitable habitat within the project area, nor is suitable habitat likely to occur once the project is completed Therefore, a biological conclusion of "No Effect" has been made Red wolf The last red wolves were found in coastal prairie and marsh habitat because this was the last area in which the animals were allowed to remain. Any habitat area in'the southeastern United States of sufficient size, which provides adequate�food, water, and the basic cover requirement of heavy vegetation, should be, suitable habitat for the red wolf Telemetry studies indicate that red wolf home range requirements vary from about 25 to 50 square miles Given the current land use practices, the project lacks good foraging habitat, although wolves may travel through the site as they follow the drainage corridor Due to their experimental population status, ,their presence cannot legally establish critical habitat. Therefore, a biological conclusion of "No Effect" has been made Red - Cockaded woodpecker Red - Cockaded Woodpeckers (RCWs) require open stands of pine, containing trees at least 60 years old and, Irving, in Which to,ezcavate their cavities. Longleaf pines (Pinus polustris) are most commonly used as cavity trees, but other species of southern pine such as loblolly, pine (Prnus toeda), are also acceptable. Foraging habitat is provided in mature (greater than 30 years old) pine and mixed pine /hardwood stands ranging from 80 to 125 acres Dense stands of hardwoods, or pine stands with a dense hardwood understory are avoided The proposed 'project area is currently, tilled cropland with several degraded headwater streams (ditches) Once .restored, the project will function as a headwater system dominated by stands of bottorriland hardwood's and pockets of emergent wetland vegetation Based on the 'habitat requirements and an onsite ireview, there is no suitable 'habitat for RCWs within the project area, nor is, sortable habitat,likely to occur once the project is completed. Therefore, a' biological conclusiornof "No Effect" has been made West4ndian manatee The West Indian Manatee is an endangered species which inhabits both marine and freshwater environments Based on the habitat requirements and an onsite review, there is no suitable habitat for Manatees within the project area, nor pis suitable habitat likely to occur once the project is completed. Therefore, a biological conclusion of "No`Effect" has been made Grassleaf arrowhead This aquatic 'her,baceous plant is rooted to the ground with stems and leaves emerging above the water surface. This species is commonly found in waterways, marshes, swamps, drainage ditches, - irrigation channels and rice crops in warmer temperate, sub - tropical and tropical environments-. Currently,, the distributionrof,this species is not found in this area.. ;Based on the habitat requirements and an, onsite review, there is no suitable habitat for this species within the project area, nor is suitable habitat likely to occur once the project is completed Therefore, a biological conclusion of "No Effect" has been made. Rough- leaved 'loosestrife This species,generally occurs irn the ecotones or edges between longleaf pine uplands and pond pine pocosins (areas of dense shrub and vine growth usually on a wet, peaty, poorly drained soil) on moist to seasonally saturated sands and on shallow organic soils overlaying sand. Rough -leaf loosestrife has also been found on deep peat in the low shrub community of large Carolina bays (shallow, elliptical, poorly drained depressions of unknown origin) The grass - shrub ecotone, where rough -leaf loosestrife is found, is fire - maintained, as are the adjacent plant communities (longleaf pine - scrub oak, savanna, flatwoods, and pocosin) The ,proposed project area is currently ,tilled cropland with several degraded headwater streams (ditches). Once restored; the project will function as a headwater system dominated by stands of bottomland hardwoods and pockets of emergent wetland vegetation. Based on, the habitat requirements,and an onsite review, there is no suitable habitat for the Rough - leaved loosestrife within the project area, nor is suitable habitat likely to occur once the ,project is completed. Therefore, a biological conclusiomof "No Effect" has been made. Sensitive Joint Vetch Sensitive -Joint Vetch grows in the intertidal zone where plants are flooded twice daily. These intertidal areas requireJunar tides, not wind driven tides that are typically found in the project area The species seems to,prefer the marsh edge at an,elevation near the upper limit of tidal fluctuation. It ,is usually found in areas where plant diversity is high (50 species per acre) and annual species ,predominate. Bare to sparsely vegetated substrates appear to be a, habitat feature of critical importance to this plant. In North Carolina, it is frequently found in the estuarine meander zone of tidal rivers where sediments transported from upriver settle out and extensive marshes are formed The project site is currently tilled cropland with several degraded headwater streams (ditches) Once restored, the project will function as a headwater stream system (swamp run) dominated by stands of bottomland hardwoods and pockets of emergent wetland vegetation. Based on the, habitat requirements and an onsite review, there is no suitable habitat for Sensitive - ,Joint Vetch within the project area, nor is suitable habitat likely to occur once the project is completed Venus' flytrap The Venus' flytrap is found in nitrogen- and phosphorus -poor environments, such as bogs and wet savannahs. Small in ,stature and slow growing, the Venus flytrap tolerates fire well, and depends on periodic burning to suppress its competition Fire suppression threatens its future in the wild. It survives in wet sandy and peaty soils. Although it has been successfully transplanted and, grown in many locales around the world, it is found natively only in North and South Carolina in the United States, specifically within a 60 -mile radius of Wilmington, North Carolina The project site is currently tilled cropland with several degraded headwater streams (ditches) Once restored, the project will function as a headwater stream system (swamp run) dominated by stands of bottomland hardwoods and pockets of emergent wetland vegetation. Based, on the habitat requirements and an onsite "review, there is no suitable habitat for this species within the project area, nor is suitable habitat likely to occur once the project is completed J.S.

Program (NCEEP) for a proposed stream restoration project located in Beaufort; North Carolina. The, proposed stream restoration project includes geomorphic modifications to five stream channels. One of these stream channels (Reach 5) is located within the 1% annual floodplain (Zone AE) of Horse Branch. The proposed work does not encroach on the floodway This study evaluates the effect of the proposed activity on the existing floodplain elevations The Flood Study included a review of available data,`the re- creation of the currently defined 19/8 annual floodplain model, and the creation of a proposed floodplain model The study revealed that there is "no rise" in Base Flood Elevation (BFE) as a result of the proposed project The proposed actions that are to occur within the 'limits of the floodplain cause negligible changes in the limits of the floodplain boundary but do not cause the flood elevation to increase. 1.2 Purpose of 'Study This Flood Study was completed to determine the effect of the proposed restoration activities within the FEMA defined 1% annual floodplain (Zone AE) on the Base Flood Elevation. This study is being completed at the request of the NCEEP in conjunction with the North Carolina Floodplain 'Mapping Program. Projects that encroach in the Special Flood'Hazard Area (SFHA)' must comply with floodplain management regulations as,a condition of participation in the, NFIP:, 13 Coordination This project included coordination with the North Carolina Floodplain Mapping Program, the Ecosystem Enhancement Program, and personnel and contractors of'FEM °A. This coordination resulted in the need for the Study being identified and the acquisition of available hydrologic and'hydraulic data that exists for the project area. 1 Hudson — Flood Study Report March 3, 2014 Section 2: Area Studied 2.1 Scope of Study This Flood Study covers the geographic area surrounding Horse Branch adjacent to the project site in Beaufort County, North Carolina. The proposed restoration work will occur on an unnamed tributary (Reach 5) to Horse Branch that enters Horse Branch on the right bank between study cross section 93 and 92. The study does not include areas of Horse Branch upstream or downstream beyond what was required for hydraulic modeling purposes. A section of Horse Branch was analyzed as part of this project as identified in the exhibits to this report. All proposed stream restoration reaches that are not located in the currently defined 1% annual flood plain are excluded from this study since they will have no effect on the base flood elevations; however, a supplemental study was performed to assess the hydraulic performance of the proposed stream channels (Exhibit 8). Section 3: Engineering Methods 3.1 Hydrologic Analyses This report relied on data provided by the FEMA Engineering Library and published data found in the Flood Insurance Study (FIS) Report for Beaufort County, North Carolina and Incorporated Areas, dated January 2, 2004. The FEMA Engineering Library did not have a hydrologic analysis for the specific section of Horse Branch that this study is concerned with; however, they were able to provide HEC -2 outputs that confirmed hydrologic data referenced in the FIS Report. The peak discharge associated with the FIRM 1% probability annual storm event (referred herein as 100 year peak discharge) for Horse Branch were developed previously through the use of regional regression equations for urban and rural areas of the piedmont region of North Carolina. These equations use drainage area size as the input to estimate peak discharges. The drainage area that was used for the study reach of Horse Branch in the FIS study was measured at Gray Road, which is approximately 1.27 miles downstream of the project site and the study reach. The 100 year peak discharge (1,180 cfs) calculated previously and documented in the FIS was used for this study. As part of the supplemental study, peak discharges of Horse Branch were also investigated using a point of analysis just downstream from the project site. This hydrologic study relied on the USGS Stream Stats model ( http:/ /water.usgs.gov /osw /streamstats /north carolina.html), which provides an interactive map to derive both drainage areas and peak discharge rates using regression equations. More information can be found at the web link provided.

The U.S. Army Corps of Engineers' HEC -RAS Version 4.1.0 was used to model Horse Branch during flood conditions. Cross sections were located at identified Base Flood Elevation contours, documented FIRM cross sections, and supplementally as necessary. National Flood Hazard Layers (NFHL) were acquired from FEMA and imported to establish the location of cross - sections and also the floodplain and floodway boundaries. Channel roughness was calculated iteratively within the range provided in the FIS associated with Horse Branch. The FIS references channel roughness coefficients in the range of 0.02 to 0.06 and overbank roughness coefficients in the range of 0.16 to 0.20. The maximum values were used in order to derive elevations that conform to those reported in the FIRM. Site photos and aerial photography confirm the likelihood of high roughness coefficients. 3 Hudson — Flood Study Report March 3, 2014 Section 4: Mapping Methods 4.1 Vertical & Horizontal Datum' The study was performed using data either provided in or transformed to the North American Vertical Datum of 1988 (NAVD 88). All elevations shown or referenced'in this study are referenced to NAVD 88. If comparisons are to be made to previously mapped elevations that reference the National Geodetic Vertical Datum of 1929 (NGVD29) a conversion factor of 7101 feet can be applied in Beaufort County All data used in this study is georeferenced to the North Carolina State Plane (FIPS 3200) referenced to the North American Datum of 1983 (NAD83) 42 Base Map Data for the development of base mapping was compiled from 20 foot DEM grid cells generated from LIDAR and distributed through NC OneMap The topographic model used for extracting cross section data to assess the, effect of the proposed restoration also included a ground run field survey for "the subject property. 4.3 Floodpl'ain and Floodway Delineation The floodplain and floodway delineation that is depicted on the FIRM Panel 5662 J with effective date of May 15, 2003 'is the result of a redelineated detailed study, The original hydraulic study provided through the FEMA Engineering Library was completed in 1982. Detailed information, including model parameters, was not able to be acquired through a reasonable research of data resources. The FIS report for the study area provided information regarding engineering methods and other documentation that was incorporated into this Flood Study- Geolocated NFHL data were imported into the drawing to provide a comparison to model results and can be seen in the map exhibits The NFHL data provided elevation data of BFEs and cross sections along Horse Branch that were used as comparisons for the model results as well as known downstream conditions 4 Hudson — Flood Study Report March 3, 2014 Section 5: Results 5.1 Floodplain Boundaries The following table provides a summary of the hydraulic modeling results. Table 3: Base Flood Water - Surface Elevation Comparison A 8 C D E F Cross Section FIRM, 511512003 Model Estimates of FIRM Increase (8 -A) Proposed Model Estimates Increase (D -8) Increase (D -A) 89 (BFE) 28 28 0 28 0 0 90 - 28.76 - 28.77 0.01 - 91(BFE) 30 30.17 0.17 30.22 0.05 0.22 92 (X -sec) 30.5 31.04 0.54 31.05 0.01 0.55 93 (BFE) 33 33.35 0.35 33.05 -0.30 0.05 94 - 33.76 - 33.43 -0.33 - 95 (BFE) 35 34.93 T -0.07 34.80 -0.13 -0.20 The model approximating the existing FIRM base flood elevations are within 1' of published values. The proposed conditions are also within 1' of the existing base flood elevations. These results confirm that there is no significant rise in base flood elevation. The floodplain boundaries were plotted on the base mapping to estimate the changes in the extent of the floodplain boundary. The grading activities in the floodplain increase the extent of the floodplain boundary landward. The increase is less than 20' and likely due to a decrease in ground elevation in the vicinity of the channel (excavation /bank grading), which allows for an increase in backwater without an increase in elevation. Other contributing differences include possible differences in compiled base mapping and roughness variability that were approximated in this study. Section 6: Supplemental Study 6.1 Hydraulic Analysis The supplemental study was provided to inform the design process and understand the expected 100 year flooding extents. Exhibit 8 provides detailed mapping and hydraulic calculations for this analysis. This study included a hydraulic analysis of the proposed design conditions using the hydrologic information provided in Table 2. The following table provides a summary of the hydraulic modeling results.
