Executive Summary In response to RFP Number 16-20190201, Clearwater Mitigation Solutions, LLC presents the following proposal for the Cool Run Mitigation Site, which will provide high quality compensatory mitigation for authorized stream and riparian wetland impacts credited through the NC DMS in -lieu -fee program and occurring within the Lumber River Hydrologic Unit Code (HUC) 03040207. The project team consists of highly experienced professionals with diverse backgrounds that lend to a multi -disciplinary approach to the mitigation effort. The team is led by Mr. Kevin Yates of Clearwater Mitigation Soutions, LLC. The Project Manager will be Mr. Christian Preziosi with Land Management Group (LMG). Grant Lewis with Axiom Environmental, Inc. (AXE) will serve as the lead for stream design and construction management. Wes Newell of Waterway Design Build, LLC will provide construction oversight and management. The restoration areas are located along Cool Run and an unnamed headwater tributary that flow directly into the Shallotte River. The Upper Shallotte River watershed (14-digit HUC 03040207020060) is a Target Local Watershed (TLW) of the Lumber River Basin. The upper portion of the Shallotte River has exhibited significant water quality impairments associated with low dissolved oxygen (DO) and pH, possibly due to swamp water conditions. The lower portions of the Shallotte River are closed for shellfish due to fecal coliform bacteria. The proposed project promotes the goals of the Lumber RBRP (2008) and specifically the Upper Shallotte River TLW by addressing the priority of restoring headwater stream channels and riparian wetlands. The anticipated functional uplift to be provided by the project will have direct benefits to on -site stream and wetlands, as well as to the downstream receiving waters and to the broader ecological health of the Upper Shallotte River watershed. CMS has secured a real estate option agreement for the purchase of easement rights on one parcel in Brunswick County, North Carolina, near the Town of Shallotte. Two options for the project are proposed for mitigation credit generation: Option 1 encompasses the entire 25.15 acres easement area and can produce 2,208 SMUs and 14.3 WMUs. Option 2 also encompasses the entire 25.15 easement area, and can yield the minimum of 2,000 SMUs and 8.0 WMU, representing the requested mitigation credits in RFP #16-20190201. Figure 9 (Appendix A) depicts the proposed easement area, which is identical for Option 1 and Option 2. Option 1 provides an additional 208 SMUs and 6.3 WMUs above the requested amount in RFP #16- 2019201. Both options provide for restoration and protection of aquatic resources with a conservation easement and will result in net gains in hydrology, water quality, and habitat functions at the Site.

Similar Project Experience Clearwater Mitigation Solutions The following project summaries highlight recent mitigation projects completed by CMS in North Carolina: Lowlands Wetland Mitigation Site (Johnston County, North Carolina) Clearwater Mitigation Solutions' (CMS) Lowlands Wetland Mitigation Site is a 71-acre, turn -key project which will provide wetland mitigation credits to Dominion Energy Transmission, Inc. (DETI) as part of DETI's Permittee Responsible Mitigation Plan (PRM) to compensate for unavoidable impacts to wetlands associated with the Atlantic Coast Pipeline Project (ACP), within the Hydrologic Unit 03020201 (Neuse 01) service area. All wetland mitigation units generated within the Site are to be utilized by DETI for the ACP within this service area. The project area is approximately 71.2 acres, of which 65.3 acres will include some form of wetland re-establishment, enhancement, or preservation with the remaining 5.9-acres of Response to Request for Proposal #16-20190201 6 1 P a g e Section E — Corporate Background and Experience uplands and non-credit area to be included within the overall conservation easement as an upland buffer. CMS identified the site, which comprised multiple land owners, negotiated with land owners, conducted initial groundwater level monitoring, identified and coordinated all survey items, helped develop and coordinate contracts with DETI's legal team and the CMS legal team, developed a mitigation plan along with the design team which was approved by the USACE in 2017 as part of DETI's compensatory mitigation plan for the ACP. Clearwater Holdings I, a subsidiary of CMS, acquired the conservation easement, with CMS overseeing construction and planting in early 2018. Ultimately, the wetland mitigation project will improve the overall function, habitat, and integrity of the degraded and drained wetlands, while preserving existing higher quality wetlands, with primary goals to: 1. Restore the primary wetland functions and values appropriate for this section of the Neuse River Lowlands. Objective: Re-establishment and conversion of the existing agricultural fields exhibiting hydric soil characteristics to a bottomland hardwood wetland. 2. Improve sediment retention and capacity for nutrient removal to offset historic agricultural practices. Objective: Filling discharge ditches, traditionally used in nutrient -enriched row crop production. Planting with native bottomland hardwood species to prevent sediment loss and provide for nutrient uptake. 3. Restoration of the attendant hydrologic and biologic functions of a bottomland hardwood forest. Objective: Restoration of appropriate bottomland hardwood wetland hydrology through filling of site ditches and restoring connectivity with adjacent surface waters. Improve surface water storage by tilling compacted soil to create microtopography. . 4. Restore and Enhance native bottomland hardwood forest. Objective: Plant native tree and understory species, including Atlantic White Cedar and Bald Cypress, within re-establishment and enhancement portions of the Site. S. Permanently protect existing higher quality bottomland hardwood forest, in addition to the remainder of the project area. Objective: Establish a perpetual conversation easement over the Site. Construction was completed in February 2018, with the goal to re-establish 23.1-acres of riparian wetlands, enhance 5.1 acres of riparian and 14.3 acres of non -riparian wetlands, and preserve 22.8- acres of non -riparian wetlands within the Site producing 24.25 riparian and 9.33 non -riparian wetland mitigation units (WMUs). The as -built data collection and survey has been completed and the site has Response to Request for Proposal #16-20190201 7 1 P a g e Section E — Corporate Background and Experience been set-up for seven years of monitoring through 2024.

The project area consists of an unnamed tributary to Sandy Creek, running along Campus Drive, within Duke University's Main Campus, which ultimately drains to Jordan Lake within the Cape Fear (HUC 03030002). The project included restoration and enhancement of approximately 3,249 linear feet of existing highly degraded and poorly functioning perennial stream channel for a total of 2,941 stream mitigation units (SMUs), within Duke University's Main Campus. The project also ties into existing Clean Water Management Trust Fund stream restoration projects downstream of the same unnamed tributary, which will incorporate a more watershed -based design approach. The Campus Drive stream restoration project created an approximate 9,500 linear foot corridor of restored stream and riparian corridor, from Campus Drive to the Duke University golf course, protected in perpetuity. CMS staff worked with Durham County Soil and Water Conservation District which agreed to hold the Conservation Easement to provide, third -party, long-term assurance to the success of the project. Although this is an urbanized setting, most of the impervious surface within the watershed is built - out and there would be little to no new impervious surface draining to the proposed project. The restoration plan also incorporated stormwater management devices, plunge pools, and stormwater wetlands in locations along the mitigation corridor where stormwater runoff is currently untreated. Due to the challenging conditions of stream restoration in Response to Request for Proposal #16-20190201 Section E — Corporate Background and Experience 8 1 P a g e the Triassic basin, the riparian areas were initially planted with larger 5 and 10-gallon trees which promoted channel stability, flood attenuation and a vegetated buffer which intercepts overland stormwater.

The Bank is located approximately 2 miles north of the City of Jacksonville in Half Moon, Onslow County, North Carolina. The site is located within the New River watershed (14-digit HUC 030300001010040) (an identified Targeted Local Watershed of the White Oak River Basin). The Bank site (approximately 363 acres) consists predominantly of channelized headwater wetland and stream systems that have been historically altered as a result of silvicultural and agricultural management practices. Streams and waterbodies within the watershed are susceptible to impairment from nutrient loading and low ambient dissolved oxygen (DO) concentrations. Response to Request for Proposal #16-20190201 10 1 P a g e Section E — Corporate Background and Experience In conjunction with the stream designer (HDR, Inc.), LMG oversaw construction management and planting. Functional uplift to stream reaches and associated adjacent wetlands have been achieved via the re-establishment of natural hydrologic and vegetative conditions that existed prior to the initiation of intensive land management in the early 1970s. Re- establishment of native vegetative communities suited to the landscape position and soil types of the project area provide for enhanced feeding and refuge habitat for resident and migratory species. Restoration and protection (via the conservation easement deed) of the riparian and non -riparian wetlands provides a habitat corridor from expansive wetland flats of Hofmann Forest to downstream bottomland hardwood forests of Bachelors Delight Swamp and New River.

Project Organization Section G. Technical Approach 1. Project Goals and Objectives The over -arching goal of the Cool Run Mitigation Project is to provide high quality compensatory mitigation for authorized stream, riparian wetland, and non -riparian wetland impacts credited through the NC DMS in -lieu -fee program and occurring within the Lumber River Hydrologic Unit Code (HUC) 03040207. The project is located within the Upper Shallotte River watershed (14-digit HUC 03040207020060), which is a Target Local Watershed (TLW) of the Lumber River Basin. This watershed exhibits water quality impairments associated with low dissolved oxygen (DO). In addition, surface waters in this area are susceptible to high nutrient concentrations (N and P) that manifest from non -point source loading associated with intensive agricultural and forestry land -use practices. Sediment loading (associated with silvicultural and agricultural drainage) is prevalent throughout the watershed. These impairments tend to be exacerbated by direct disturbances to streams and wetlands (such as prior channelization of streams and historic drainage of wetlands). The cumulative effects of such practices result in diminished nutrient uptake and nutrient/sediment loading to down -gradient waters. Cool Run is located within an area subject to some of the highest rates of population growth in the country'. Rapid growth and development has presented a suite of additional stressors to water quality within the watershed including run-off associated with increased impervious cover. While forest remains the dominant land cover at over 34%, the Long Bay Subbasin is the most impervious subbasin in the Lumber River Basin (NC DENR 2010). The proposed project promotes the goals of the Lumber River Basinwide Water Quality Plan (2008) and specifically the Upper Shallotte River TLW by addressing the priority of restoring headwater stream channels and riparian wetlands. The primary goals and objectives of this stream and wetland restoration project focus on the following (goals listed first followed by objectives in bullet form): 1. Improvement of hydraulic connectivity to floodplains and enhancement of flood attenuation • Restoring the existing highly modified and incised channel using predominantly Priority 1 restoration techniques where bankfull and larger flows will more readily access the historic floodplain; • Restoring streams on -site using Priority I restoration techniques will enhance the Site's ability to mitigate flood flows by reconnecting bankfull and higher flows to its historic floodplain; Brunswick County was recently identified as the fastest growing county in the state. According to the U.S. Census Bureau (2017), Brunswick County's population increased by 21.8 percent, or by 23,466 people between 2010 and July 2017. In addition, Brunswick County's metro area, which includes Myrtle Beach and Conway, was the second fastest growing area in the country. Response to Request for Proposal #16-20190201 11 P a g e Section G. Technical Approach • Removing adjacent earthen berms (spoil from historic channel modification) from the floodplain will afford more natural valley access for floodwaters, in turn attenuating flows and assisting in hydrating riparian areas that are largely severed from interaction with existing stream channels; and • Restoring riparian wetlands adjacent to the restored channels will assist in attenuating floodwaters, thus reducing sediment and nutrient loading to downstream waters. 2. Raising near -surface groundwater hydrology in floodplain/riparian areas to assist in the restoration of wetlands and to increase the Site's ability to uptake and store pollutant inputs • Restoring the bed elevations of the stream channel into its relict channel will re- establish surface water inflows and groundwater storage within riparian wetlands, thus promoting the uptake, storage and fixation of nutrients and sedimentation from overbank flows. • Removing spoil from relic wetland areas will re-establish natural contours and floodwater storage thus contributing to enhance nutrient uptake/transformation and sediment retention. 3. Reduction of sediment loss from degraded banks that affects water quality and aquatic habitat • Restoring the degraded, straightened and incised stream as primarily a Priority 1 restoration where bankfull and larger flows can access the floodplain allows nutrients, sedimentation, and debris from upstream silvicultural land use to settle within the floodplain to a greater extent than existing conditions. • Restoring a stable dimension, pattern, and profile by re -connecting to the relict channel. Doing so will allow for the channel to transport and attenuate watershed flows and sediment loads without aggrading or degrading. Priority 1 restoration will increase flood interaction with the floodplain, thereby increasing capacity for nutrient uptake and pollutant removal prior to discharge to downstream receiving waters. • Stabilizing channel banks by restoring the channel to its relict location in the low point of the valley and utilizing in -stream structures (where deemed suitable) to reduce shearing forces on outside meander bends, and planting native vegetative species to provide soil stability will reduce stream bank stressors. 4. Enhancement of aquatic, semi -aquatic and riparian habitat • Restoring the channel to a sand bed system with meanders and natural structures that promote invert scour and pool development fosters improved aquatic habitat for benthic macroin vertebrate and fish propagation. Woody materials such as log structures, overhanging planted vegetation and toe wood in submerged water will Response to Request for Proposal #16-20190201 2 1 P a g e Section G. Technical Approach provide a diversity of shading, bed form and foraging opportunities for aquatic organisms. • Restoring wetland hydrology and introducing floodwaters back to the historic floodplain will provide a diversity of habitats for semi -aquatic flora and fauna. S. Protecting, preserving and enhancing stream and wetland habitat within and adjacent to agricultural and silvicultural site • Restoration and protection (via the conservation easement deed) of the riparian wetlands provides a habitat corridor from the upper reaches of a first -order stream to downstream bottomland hardwood forests of Shallotte River. Long-term protection is considered particularly beneficial in light of intensive development pressures within the subbasin and the susceptibility of downstream waters to shellfish closures (attributed to stormwater runoff). The anticipated functional uplift to be provided by the project will have direct benefits to on -site stream and wetlands, as well as to the downstream receiving waters and to the broader ecological health of the Upper Shallotte River watershed. This is particularly beneficial in light of the extent and severity of water quality impairments of surface waters of the Shallotte River and the threat to existing stream and wetland habitats as a result of intensive development pressures along this stretch of the southeastern North Carolina coast. 2. Project Description A. Site Location The project site is located in Brunswick County, approximately five miles southwest of the city limits of Shallotte, North Carolina and north of State Route 1316 (Old Shallotte Rd NW) (refer to Figure 1). As indicated above, Cool Run is a first -order tributary located within the Upper Shallotte River watershed (14-digit HUC 03040207020060), which is a Target Local Watershed (TLW) of the Lumber River Basin (Figure 2). The riparian wetland restoration areas are situated within the floodplain of the relict channel of Cool Run which has been historically re-routed (to the edge of the floodplain), straightened, and deepened. The manipulated channel of Cool Run drains into the Shallotte River approximately 2.0 river miles downstream from the project area (refer to Figure 3 and Figure 4). B. Watershed and Water Quality Classification Cool Run has a NC DEQ surface water classification of C; SW. The classification "C" denotes waters protected for secondary uses such as secondary recreation, fishing, wildlife, fish consumption, aquatic life including propagation, survival and maintenance of biological integrity, and agriculture. "Secondary recreation includes wading, boating, and other uses involving human body contact with water where such activities take place in an infrequent, unorganized, or incidental manner." The "SW" classification is a supplemental classification intended to recognize those waters which have low velocities and other natural characteristics which are different from adjacent streams. Response to Request for Proposal #16-20190201 3 1 P a g e Section G. Technical Approach C. Physiography. Geology, and Soils The Cool Run mitigation site is located within the Carolina Flatwoods of the Middle Atlantic Coastal Plain Ecoregion (63h). In general, this ecoregion is characterized by nearly level coastal plain with less relief and larger areas of poorly drained soils than the adjacent, higher elevation Southeastern Plains to the west. The Carolina Flatwoods were covered by shallow coastal waters during the Pleistocene, and the resultant terraces tend to consist of fine -loamy and coarse -loamy soils, with periodically high water tables. Other areas have clayey, sandy, or organic soils, contributing to the region's plant diversity. The region is a significant center of endemic biota, with high biological diversity and rare species compared to adjacent regions. Artificial drainage for forestry and agriculture is common. Elevations of the site range from 52 ft above mean seal level (AMSL) along the northeastern boundary to 38 ft AMSL where Cool Run exits along the southern boundary. The soils formed in unconsolidated sand, silt, and clay deposited by water. They are nearly level to sloping. Soils of the site consist of very poorly drained loams in drainageways to moderately well -drained loamy sands along convex stream terraces (refer to Figure 5). Mapped soil series occurring on the site and their associated properties are summarized in Table 1. Areas proposed for stream and riparian wetland mitigation occur within the poorly drained Muckalee loam soil series. Profile descriptions of on -site soil borings (prepared by a NC Licensed Soil Scientist) are provided in Appendix A. Table 1.

Existing Conditions 1. Stream Tributaries The property is currently managed for agricultural and silvicultural production with the majority of the mitigation area occurring within the previously harvested floodplain of Cool Run. The natural hydrologic conditions of the site have been historically altered by the relocation, straightening, and Response to Request for Proposal #16-20190201 4 1 P a g e Section G. Technical Approach deepening of the Cool Run tributary and an unnamed tributary to Cool Run (UT-1) and subsequent installation of several shallow surface ditches within the riparian floodplain. The altered channel and ditches appear on historic aerial photos dating back to the 1950s (see historical site aerial photography in Appendix B). The project site consists of the headwaters of Cool Run (a first -order tributary of the Shallotte River), an unnamed tributary to Cool Run (UT-1), and former wetland areas historically impacted by prescribed site drainage practices. The stream reaches and highly degraded riparian areas lie within topographic crenulations characteristic of fluvial systems. Cool Run appears to have been relocated and channelized in the late 1950s. UT-1 appears to have been channelized prior to 1956. Historic channelization has resulted in the disconnection of the stream channels from their adjacent riparian floodplain and effectively drained riparian wetlands. The extent of the conservation easement boundary is depicted on the 1998 aerial and 2016 aerial in Figure 6 and Figure 7, respectively. The existing conditions plan view (with stream features, NC SAM form locations, and cross-section locations as further described below) is provided in Figure 8. Site specific mitigation goals and objectives have been developed through the use of the North Carolina Stream Assessment Method (NC SAM) analyses of existing stream systems at the Site (NC SFAT 2015). Site functional assessment data forms are available upon request and model output is included in Appendix C and is summarized in the following table. Metrics targeted to meet the Site's goals and objectives are depicted in bold, within Table 2 below. a. Cool Run Cool Run enters the Site as a low -gradient, first order perennial tributary and maintains first order status through the Site (USGS 1946). Cool Run generally flows from the northeast to the southwest and south through the proposed mitigation site. The channel continues south along the outer, eastern edge of an impounded pond that is on the adjacent property to the west. Cool Run flows south across US Highway 17 into the Shallotte River (approximately 2 river miles south of the mitigation site). Cool Run enters the site via an incised and straightened channel that drains approximately 1.62- miles of timberlands to the north (USGS Stream Stats). The stream is a sand -bed system that has been highly modified in the past. Historical aerials confirm ditching of the site beginning in the late 1950s. Evidence of ditching includes spoil piles which act as berms along both banks. The channel predominantly flows along the left valley shoulder (outside of the natural floodplain) as it enters the site and then transects the floodplain to where it flows along the upper edge of the right valley. The existing Cool Run channel lacks any natural meander geometry. Fortunately, the relic (abandoned) natural channel was not filled during prior site alteration and remains throughout the length of the valley (as evidenced through LiDAR imagery and subsequently verified through field investigations). These relic sections of the channel will be utilized in further assessments during determination of reference conditions and mitigation planning. Channel bed form is absent of deeps/pools which would be commonly found in highly functional and sinuous Coastal Plain stream channels. Channel banks are high, nearly vertical and display lengths of bare soils that are eroding because the channel is incised below the rooting depth of adjacent vegetation. Channel banks are high because: • anthropogenic disturbances that have intentionally deepened the channel; • spoil from channel modifications has been cast off to the top of bank, which raises the ground surface along the bank and; Response to Request for Proposal #16-20190201 5 1 P a g e Section G. Technical Approach • the channel has been relocated to the edge of the valley where topographical relief is significantly greater than within the flatter valley floor. Table 2.

The Ee Width from River Left to Right(R) width-t,Depth Ratio: 7.2 entrenchment ratios is 1.5, while E,ft—hme„t Mt :1.9 Bii 3.3 the bank height ratios is 1.9. Generally, the bankfull flow stage appears to be approximately at the low bank height. Geomorphic data confirms the containment of bankfull and higher flows within the channel. Data from the cross -sections (Appendix D) indicate that Cool Run can generally be classified as a G type stream, which is indicative of an unstable system. It should be noted that geomorphic parameters that influence channel classification have been significantly influenced by anthropogenic modifications. As indicated above, the relic channel remains relatively intact with characteristic channel geometry and meanders throughout much of the natural valley. However, due to the channelization and relocation of the Cool Run tributary, the relict channel exhibits no flow patterns. b. Un-named Tributary (UT)-1 A small stream channel with a relatively small drainage area (approximately 70-acres) enters the Site and converges with Cool Run (USGS Stream Stats). This stream (UT-1) is denoted as a blue line on the 1943 USGS Shallotte quadrangle. However, valley crenulations are only depicted on the 1990 USGS quadrangle. Additionally, the digital elevation model (DEM) (Figure 4) clearly depicts crenulations in the landscape, indicating natural valleys are present at the UT-1 tributary. A summary of channel: characteristics is previously depicted in Table 3. A NC DWR Stream Identification Form was completed on UT-1 which scored 27.5 indicating the ditches channel is intermittent, or headwater in nature (Appendix Q. UT-1 has been modified (i.e. ditched) to promote drainage within the adjacent agricultural fields. The channel is a sand bed system that has been ditched and straightened through its valley; therefore, there is no natural meander geometry or pool formation. The channel has a planar Response to Request for Proposal #16-20190201 7 1 P a g e Section G.

It appears that flood flows rarely access UT-1's adjacent valley in the upslope portions of the Site or within Cool Runs floodplain. c.

Sediment Model Sediment load modeling was performed using methodologies outlined in A Practical Method of Computing Streambank Erosion Rate (Rosgen 2009) along with Estimating Sediment Loads using the Bank Assessment of Non -point Sources Consequences of Sediment (Rosgen 2011). These models provide a quantitative prediction of streambank erosions by calculating Bank Erosion Hazard Index (BEHI) and Near -Bank Stress (NBS) along each Site reach. The resulting BEHI and NBS values are then compared to streambank erodibility graphs prepared for North Carolina by the NC Stream Restoration Institute and NC Sea Grant. Streambank characteristics involve measurements of bank height, angles, materials, presence of layers, rooting depth, rooting density, and percent of the bank protected by rocks, logs, roots, or vegetation. Site reaches have been measured for each BEHI and NBS characteristic and predicted lateral erosion rate, height, and length to calculate a cubic volume of sediment contributed by the reach each year. Data forms for the analysis are available upon request and the data output is presented in Appendix F. Results of the model are presented in Table 4 below. Table 4.

Wetland Conditions Wetlands within the project area have been historically altered via drainage and conversion to timber and/or agricultural management. Surface water inflow via overbank flooding no longer occurs with the floodplain of the channelized streams. Groundwater levels have been significantly lowered to the extent that the adjacent riparian zone within the proposed restoration area is no longer considered jurisdictional wetlands as evidenced by the lack of primary indicators of wetland hydrology. This in turn has resulted in subsidence and oxidation of surface organics and has contributed to a shift in vegetative assemblages (i.e. recruitment of drier species). In addition, the vegetative assemblage has been historically altered from conversion to monotypic loblolly pine plantation and subsequent harvesting. Canopy species within the immediate riparian zone (i.e. within SO feet more or less) of the upper reach consist of sweet gum (Liquidambar styraciflua) and red maple (Acer rubrum) (i.e. species more representative of altered sites). The understory consists of species characteristic of drained sites such as horse sugar (Symplocos tinctoria), American beautyberry (Callicarpa americana), dog fennel (Eupatorium capillifolium), and muscadine grape (Vitis rotundifolia). Areas lacking wetland hydrology are targeted for wetland restoration (e.g. re- establishment) as described further in Section 3B below. In the downstream portion of the site, few remnant canopy specimens of characteristic species such as tulip poplar (Lirodendron tulipifera), and swamp chestnut oak (Quercus michauxii) persist. The sub -canopy and shrub strata in these area include fetterbush (Ilex glabra) and American holly (Ilex opaca). However, subsidence, lack of hydrologic indicators, and the presence of vegetative species indicative of drier conditions illustrate drainage through much of the reach within the project area. Microtopographical depressions remain within the floodplain (including portions of Response to Request for Proposal #16-20190201 9 1 P a g e Section G. Technical Approach the relic channel). These areas appear to meet the three parameters of wetland hydrology but lack characteristic riparian wetland hydrology (i.e. intermittent to seasonal inundation with surface water inflow from stream overbank flooding). Restoration of the Cool Run tributary to its original location within the central portion of the valley will allow for the rehabilitation of wetlands that have been historically impacted. Up -gradient riparian wetland areas on the eastern edge of the valley have been disconnected from the floodplain by a toe -slope interceptor ditch which has resulted in a lowered groundwater condition. However, wetland hydrology of the adjacent seeps and headwater wetland areas still persists (though with apparent reduced hydroperiods). As result, these wetland areas are targeted for enhancement (refer to Figure 8 for the Existing Conditions Plan View). Riparian wetlands associated with much of the reach of Cool Run are classified as Headwater Forest wetland type that grade to Bottomland Hardwood Forest wetland type (NCWAM 2010) just south of the mitigation site. UT-1 is classified as Headwater Forest wetland type (NCWAM 2010). The stream reach grades to Riverine Swamp Forest down -gradient where overbank flooding would normally be a more significant source of water in an unaltered condition. Based upon Schafale and Weakley (1990), the riparian wetlands of the project area are considered Small Stream Swamp (Blackwater Subtype) grading to Bottomland Hardwood Forest (Blackwater Subtype). These wetland types are intermittently to seasonally flooded in an unaltered condition. Principal sources of hydrology are groundwater seepage, diffuse surface flow, and overbank flooding. Downstream sections of Cool Run would exhibit greater hydrologic input from higher frequency overbank flooding events (NCWAM 2010). Photographs of existing site conditions are provided in Appendix G. The limits of the proposed restoration and enhancement are depicted in Figure 9 and are described in more detail in Section 3B below. E. Jurisdictional Streams and Wetlands As indicated above, historic drainage practices associated with silvicultural and agricultural management have resulted in the interception of surface water, the lateral drawdown of groundwater, and the reduction/removal of overbank flooding in former riparian wetland areas. Some depressions within the floodplain (including those associated with the relict stream channel) exhibit higher groundwater levels. In addition, up -gradient riparian wetland areas on the eastern edge of the valley also retain indicators of wetland hydrology. These areas are considered to be jurisdictional wetlands as regulated by the U.S. Army Corps of Engineers (USACE) and the NC Division of Water Resources (DWR) (refer to Figure 8). No other wetlands were identified within the project area as part of the site assessments. However, a complete wetland delineation with USACE review and concurrence will be performed as part of the mitigation plan development. The delineation will culminate in the issuance of a final jurisdictional determination (JD) issued by the USACE prior to approval of the final mitigation plan. All channels identified for single -thread or headwater stream restoration meet the definition of jurisdictional Waters of the United States as each exhibits a continuous Ordinary High Water Mark (OHWM). NC DWR Stream Identification Forms have been completed for each of the on -site channels proposed for restoration. The entire length of the Cool Run is considered perennial. The UT-1 headwater stream channel is considered intermittent. Response to Request for Proposal #16-20190201 10 1 P a g e Section G. Technical Approach F. Cultural Resources Section 106 of the National Historic Preservation Act requires federal agencies to take into account the effects of their undertakings on historic properties. LMG reviewed the State of North Carolina's online cultural resource database (HPOWEB GIS Service) to determine if any cultural resources and/or historic properties have been recorded within or near the project area. According to their website, there are no sites or features listed in the National Register of Historic Places within or adjacent to the project site. Attached is a map illustrating documented cultural and historic resources in the vicinity of the project area (Appendix H). G. Threatened and Endangered Species Species with the federal classification of Endangered (E), Threatened (T), or Officially Proposed (P) for such listing are protected under the Endangered Species Act (ESA) of 1973, as amended, and the Bald and Golden Eagle Protection Act. The US Fish and Wildlife Service's Information, Planning, and Consultation (IPaC) system was used to determine federally -protected species that are known to occur in the general project vicinity (Table 5). Furthermore, a search of the North Carolina Natural Heritage Program database was conducted to identify areas within or around the site that are already known to support rare species. According to their files, no federally or state -protected species are known to occur within the site. One historical record of a state -listed dragonfly has previously been identified within a one -mile radius of the site (see Appendix H). The presence of any plant or animal species is determined by the availability and abundance of suitable habitat. Staff of LMG performed a limited site evaluation to identify community types within the site that may support federally -protected species. The property is currently managed for silvicultural and agricultural production (including recent harvesting along the majority of the project area). Cool Runs has been channelized over the years and former wetlands areas adjacent to the channel (proposed riparian wetland restoration) have been drained. The riparian areas (in areas without harvesting) currently support a canopy of red maple and sweetgum with a fairly dense subcanopy and shrub layer that supports horse sugar, American beautyberry, and American holly, and gallberry (Ilex glabra). The riparian areas are classified as Bottomland Hardwood Forest (NCWAM, 2010). Downstream of the project site consists of Bottomland Hardwood Forests grading to Riverine Swamp Forest and high -order stream channels that have the potential to support American alligator. However, these areas are located off the property. Proposed mitigation work would not have an adverse effect on any federally -listed species. Outside of the stream valley, the site consists of convex ridges and interstream flats and depressions. These areas are actively managed for silvicultural and agricultural production and generally consist of active farm fields and harvested areas. Based upon preliminary site evaluations and findings, these areas do no support habitat suitable for listed species. Overall, the proposed mitigation work would not have an adverse effect on any federally -listed plant or animal species. However, headwater stream restoration will promote enhanced water quality and habitat for aquatic and semi -aquatic species that will in turn beneficially affect listed species such as the American alligator and bald eagle. Upon award of contract, an environmental screening will confirm these findings. Response to Request for Proposal #16-20190201 11 I P a g e Section G. Technical Approach Table 5.

It is anticipated that the provider will submit a Floodplain Development Permit as a courtesy to the County to inform them of the project. I. Site Constraints The site is well -suited for achieving the preferences as indicated in the RFP based upon its soil types, landscape position, hydrology, extent of previous human alteration, lack of physical constraints, and connectivity to relatively undisturbed bottomland hardwood forest offsite. There are no known site constraints that would impede or adversely affect the restoration, enhancement, or preservation of streams and wetlands of the project area. 3. Project Development The Proposal documents one Mitigation Option for the proposed cataloging unit. See Figure 9 for the Proposed Mitigation Map. Proposed mitigation is summarized as: Summary of Streams • Cool Run — Restore natural pattern, profile and dimension to approximately 2055 feet of Cool Run within the Site limits by redirecting stream flow into the historic abandoned channel. • UT 1— Restore a headwater stream to approximately 370 feet of valley which constitutes UT 1 within the Site limits. Summary of Wetlands • Riparian Wetland Restoration — re-establish characteristic wetland hydrology via raising of stream bed elevations and removal of spoil piles (re-establishment of surface water inflows and groundwater storage); plant areas lacking characteristic wetland tree and shrubs; connection of existing wetlands to floodplain and stream • Riparian Wetland Enhancement — re-establish characteristic wetland hydroperiods via backfilling or plugging of toe -slope ditches and connection to the down -gradient floodplain; plant areas lacking characteristic wetland tree and shrubs Response to Request for Proposal #16-20190201 13 1 P a g e Section G. Technical Approach A. Proposed Stream Mitigation 1. Cool Run Stream restoration efforts are designed to restore a stable stream that approximates hydrodynamics, stream geometry, and local microtopography relative to reference conditions. The channel is incised (as evidenced by elevated bank height ratios approaching and exceeding 2.0), channelized and significantly influenced by adjacent berms that were created when the Site was modified in a regional drainage effort. It is evident that bankfull/channel forming and higher flows rarely access the historic floodplain within the proposed restoration reach, causing increased stress and subsequent erosion within the banks and increased drainage of groundwater from the adjacent floodplain. It is anticipated that Cool Run will be restored as a Priority I (PI) restoration where the bankfull elevation matches the historic/abandoned floodplain. Sections of relic natural channel within the floodplain will be located during topographical surveys and utilized in the restoration design to the greatest extent practical. Priority II stream restoration techniques may be utilized in the upper and lower reach of the Site tributaries to tie the channel into the existing ditches above and below the Site. Priority II reaches will be minimized to the maximum extent feasible. Additionally, removal of the extensive berm network that currently blocks flood access to the floodplain will allow above - bank flows to access the entire valley. The use of in -stream structures for grade control and habitat is essential for successful stream restoration. It is anticipated in stream structures may be incorporated into the channel design in an effort to increase in -stream foraging and propagation habitat, promote a diversity in bed form, and provide immediate bank stability in higher stress areas. In -stream structures may be placed in the channel to elevate local water surface profiles in the channel, potentially flattening the water energy slope or gradient and directing stream energy into the center of the channel and away from banks. The structures will consist of log cross -vanes or log j-hook vanes. In addition, the structures will be placed in relatively straight reaches to provide secondary (perpendicular) flow cells during bankfull events. The mitigation plan will strive to minimize impacts to mature specimen trees within the valley of Cool Run. It is anticipated that trees 12 inches and greater will be located during topographical surveys in an effort to reduce impacts to mature vegetation during design and subsequent construction. Any portion of the existing buffer that is removed to facilitate restoration of the channel will be replanted with native vegetation characteristic of a Coastal Plain Bottomland Hardwood Forest community (Schafale & Weakley 1990) (refer to proposed planting below). 2. UT-1 Headwater channel restoration is proposed for the valley of UT-1. UT-1 was historically straightened and depended in an effort to promote rapid drainage through historic wetlands. The proposed mitigation plan is anticipated to include the filling of existing ditched channels, installation of valley sills using natural native materials, removal of berms through the valley, restoration of natural contours, and restoration of natural vegetation that is adapted to headwater conditions. Removal of the drainage effects of the ditched channels should greatly improve the storage and filtering function of the headwater valley, provide attenuation for storm water flows from the contributing watershed, provide semi -aquatic habitat for various fauna and flora, and provide a significant carbon source for downstream receiving waters associated with Cool Run. Response to Request for Proposal #16-20190201 14 1 P a g e Section G. Technical Approach 3. General Description of Stream Mitigation Activities It is anticipated that construction of the Site will begin at the upstream extents of the valleys on -site and work downstream. Standard construction equipment including CAT 320 (or equivalent) track hoes, dozers, and track trucks will be utilized to clean -out and re-establish the relict channel. Erosion control measures such as a pump -around operation with silt bags, silt checks, erosion control matting, seeding and mulch will be implemented during construction. Grading quantities cannot be determined until after site design which will occur in the Mitigation Plan phase. However, earthwork is anticipated to be relatively minimal since the bankfull channel of Cool Run will be reconnected to the original floodplain for the majority of the restoration (i.e. Priority restoration) and because UT-1 will be restored as a headwater channel through the valley. The desired plant community and species types will be established by utilizing a reference forest system, but may include species found within the existing wooded forest along the southern end of the Site along Cool Run. Planting densities of bare root species at approximately 680 trees per acre are anticipated for areas of restored vegetative buffer. Soil amendments may be added during and following construction to promote grass and tree growth within the disturbed areas on -site. Signs will be posted along the easement boundary to clearly demarcate the easement boundary for the landowners. 4. Summary of Stream Function Uplift It is anticipated that all mitigation activities will substantially increase net ecological, hydrologic and hydraulic functions to Cool Run, and the headwater stream valley associated with UT 1, and downstream receiving waters. Functional uplift is expected to include the following: • Stabilizing stream channel side slopes and invert on Cool Run through reconnection to the historic channel, coir fiber matting, and establishment of permanent native vegetation (grasses and trees). • Removal of eroding channel side slopes on UT's by filling channels and grading to natural contours. • Creating stable and productive in -stream habitat within Cool Run through a more natural plan form geometry that promotes deeps and shallows throughout the channel. • Introduction of woody materials into the channel of Cool Run such as toe wads and logs sills that will provide refuge habitat for fish and semiaquatic species, foraging habitat for macrobenthos, channel depth variability, stream shading, and invert stabilization. • Installation of riparian and bank vegetation that will add woody debris to the channel for foraging and refuge and will shade the channel which will regulate temperatures and stabilize dissolved oxygen. • Connecting higher than bankfull flows to its historic floodplain, which will decrease channel shear stress, promote attenuation of water across the broad floodplain, drop and store suspended solids on the floodplain, filter nutrients, pesticides and other pollutants, and rehydrate the riparian buffer to allow for greater groundwater and surface water storage. • Removal of the drainage effects of the ditched channels of UT-1 should greatly improve the storage and filtering function of the headwater valley, provide attenuation for storm water flow from the contributing watershed, provide semi -aquatic habitat for various fauna and flora and provide a significant carbon source for downstream receiving waters associated with Cool Run. Response to Request for Proposal #16-20190201 15 1 P a g e Section G. Technical Approach 5. Reference Streams Stream reference reaches will be incorporated into the Natural Channel Design to assist in determining morphological parameters for the restored channels. The design team has restored numerous single thread and headwater streams within the same Ecoregion as the Site and have previously identified and surveyed several suitable reference streams (both single thread and headwater) that have been approved through agency coordination and used in Mitigation Plans. It is anticipated that these previously surveyed and approved reference sites will be used to assist in completion of the Site design. B. Proposed Wetland Mitigation Approximately 14.2 acres of former riparian wetland (or highly degraded wetland) associated with the channelized tributaries have been targeted for restoration. As discussed in the previous section, these areas have been historically drained through silvicultural and agricultural management activities over the past five decades. The riparian restoration will occur within the existing crenulation of the stream bottom via re-establishment of the original stream channel geometry and bed elevation resulting the reconnection to the stream to adjacent riparian areas. The reconnection of the stream and adjacent riparian wetlands (in concert with the removal of other on -site ditches) will restore characteristic hydroperiods (via minimizing subsurface drainage and increasing overbank flooding within the adjacent floodplain). The proposed restoration footprint for these areas has been identified via contour LIDAR data, geomorphic data, and observed field conditions. The final footprint will be premised on more detailed site investigations and an approved wetland delineation (i.e. jurisdictional determination). Modeling of similarly -sized stream reaches have demonstrated sufficient hydrologic inflow resulting from elevation of static groundwater elevations and periodic overbank flooding in response to precipitation events. Earthwork will include the backfilling of the existing, channelized segment of Cool Run and the re- establishment of the relict Cool Run tributary. Existing spoil piles will be removed (i.e. will be utilized to backfill ditches). In addition, the ditch located on the eastern toe of slope of the valley will be plugged and/or backfilled to remove its drainage influence. Earthen material from side -cast spoil will be used to backfill the adjacent ditches. Material will be consolidated to effectively impede drainage. As a result, portions of the roadside ditches will remain as open water habitat pending final cut/fill volumes. Clay plugs will be installed at prescribed intervals and will be reinforced with filter -fabric and rip -rap to ensure long-term stability and functioning. Areas within the valley that are graded will be disked, straw -mulched, and planted. Prior to any grading work, appropriate federal and state authorizations will be obtained for earthwork (including a Nationwide Permit 27). Erosion control measures to prevent sediment from leaving the site will include installation of check dams within downgradient sections of ditches to be backfilled and/or plugged. Areas to be graded will be stabilized with straw mulch and temporary and permanent seeding. In addition, all graded areas will be planted with characteristic wetland tree bare -root seedling and containerized wetland shrubs (per the planting plan in the final, approved Mitigation Plan). Response to Request for Proposal #16-20190201 16 1 P a g e Section G. Technical Approach The proposed restoration areas will be planted with species typical of a small stream swamp community (Figure 9). Much of the restored riparian wetland valley will be re -planted due to the lack of characteristic riparian wetland vegetation. As indicated above, much of the area consists of non -target species characteristic of drained sites. Areas to be replanted will be drum -chopped and or bush -hogged prior to planting. Areas with existing, suitable canopy species (at the southern terminus of the site) will be left intact with larger specimen trees of target species located and preserved. Plantings of the riparian valley will include installation of bare -root seedlings of bald cypress (Taxodium distichum), swamp tupelo (Nyssa biflora), ironwood (Carpinus caroliniana), and swamp chestnut oak. It is expected that other characteristic species will recruit naturally into these restored areas upon successful hydrologic restoration. C. All Mitigation It is anticipated that Priority I restoration will be utilized throughout Cool Run to the maximum extent practical. Several in -stream woody structures such as densely vegetated soil lifts, toe wood, log sills, and cover logs are anticipated to be incorporated into the channel design. The final bankfull channel size will be determined during the Mitigation Plan; however, preliminary data suggests that the channel will be designed as moderately low width -to -depth ratio C or E type channel that conveys the bankfull discharge. Additionally, the contributing UT-1 will be restored as headwater streams within the Site. It is anticipated that UT-1's existing channel will be filled, and the valleys graded to natural contours that mimic pre -disturbance conditions. 1. Site Planting The majority of the hardwood riparian buffer has been removed from the Site, with portions of buffers, primarily on the UT-1, being comprised of agricultural field. The proposed buffer width includes a minimum of the required 50 foot stream buffer; however, the proposed buffer will extend out to 100 ft or greater. It is anticipated that trees 12 inches and greater will be surveyed within the restoration area in an effort to ensure protection of mature vegetation during design and subsequent construction. Portions of the existing buffer that are removed to facilitate restoration of the channels will be replanted with native vegetation. The proposed mitigation site will provide for the establishment of natural plant assemblages occurring within riparian habitats of the Coastal Plain. Target species to be planted have been identified based upon site -specific information (including soil profiles and evaluation of landscape position). The proposed planting regime will result in a mature community characteristic of specific wetland community types. Establishment of a characteristic plant community will provide for the necessary structure for resident and migratory fauna utilizing these types of habitat. The project is expected to benefit a range of fauna by providing for a contiguous habitat corridor suitable for refuge, nesting, and feeding. In addition, project activities are expected to contribute to enhanced water quality conditions beneficially affecting downstream faunal communities. The final planting plan will be premised on a comprehensive vegetation survey of adjacent wooded areas as well as site soils and hydrology such that selected native trees will be well -suited to the site -specific conditions of the property to promote high survivorship rates. No existing exotic or invasive species have been observed within the project area. However, the mitigation plan will also incorporate an invasive species management plan and protocol that can be implemented should invasive species volunteer into the site. Note that the graded areas will also be planted with bare - root seedlings, and live stakes of appropriate species (black willow, silky dogwood, and/or Response to Request for Proposal #16-20190201 17 1 P a g e Section G. Technical Approach elderberry) will be installed. Planting densities of bare root species at approximately 538 to 680 trees per acre are anticipated for the restored vegetative buffer, but may be lower in areas that may only require supplemental plantings. Soil amendments may be added during and following construction to promote grass and tree growth within the disturbed areas on -site. Species selection and distribution will be matched closely to micro -site hydrologic and edaphic conditions. In other words, species more tolerant of poorly drained soils (e.g. bald cypress) will be planted within lower landscape positions generally consisting of the Muckalee soil series while species characteristically occurring in better drained soils will be planted in slightly higher convex landscape positions. 2. Stream Crossings There are currently no stream crossings within the Site. 3. Easement Boundary Protection Marking of the easement boundary will be provided in the form of signage which will demarcate the bounds of the conservation easement. D. Mitigation Quantities This proposal details one Mitigation Option that is summarized in Table 6 below. Note that the table reflects stream credit and riparian wetland credit projections in excess of the requested amounts in the RFP. While the project team anticipates overage on credits for these mitigation types, it is understood that the contracted amount will not exceed the requested quantities (2,000 stream credits, 8.0 riparian wetland credits). The proposed project will satisfy all the credit needs identified in the RFP. Table 6.

Current Ownership and Long Term Protection CMS has secured a real estate option agreement for the purchase of easement rights on one prcel in Brunswick County, North Carolina, near the Town of Shallotte. Upon project award and completion of the Categorical Exclusion document (Task 1), CMS will record a Conservation Easement on the project area. The easement will be conveyed to the State of North Carolina for protection of the property in perpetuity. F.

G. Success Criteria Upon completion of the restoration project, a Baseline Monitoring Report will be prepared and submitted to the NC DMS to document the extent of the mitigation performed. The report will include all information required by DMS monitoring guidelines including photographs, plot locations, and documentation of existing species density and composition. The performance standards shall be consistent with the requirements described in the Federal rule for compensatory mitigation project sites as described in the Federal Register Title 33 Navigation and Navigable Waters Volume 3 Chapter 2 Section § 332.5 paragraphs (a) and (b). Additionally, the October 24`", 2016 "Notification of Issuance of Guidance for Compensatory Stream and Wetland Mitigation Conducted for Wilmington District" will be used to not only to determine monitoring requirements but also success criteria. Criteria below are preliminary conceptual success criteria and may change upon approval of the final mitigation plan. Response to Request for Proposal #16-20190201 19 1 P a g e Section G. Technical Approach 1. Streams The restored stream reaches are proposed to be monitored for geomorphic activity. Annual fall/winter monitoring will include development of channel cross -sections on riffles in addition to visual observation of channel stability. A longitudinal profile of the thalweg, water surface, bankfull, and top of bank will be collected during the as -built survey of the constructed channel. a. Stream Dimension General maintenance of a stable cross-section and hydrologic access to the floodplain features over the course of the monitoring period will generally represent success in dimensional stability. Some changes in dimension (such as lowering of bankfull width -to -depth ratio) should be expected. Riffle sections should generally maintain a Bank Height ratio approaching 1.0 —1.2, with some variation in this ratio naturally occurring, and display an entrenchment ratio of no less than 2.2. Both ratios should display no more than 10 percent change from year-to-year. Pool sections naturally adjust based on recent flows and time between flows; therefore, more leeway on pool section geometry is expected. b. Stream Pattern and Profile Pattern features should show little adjustment over the standard 7 year monitoring period. The profile should not demonstrate significant trends towards degradation or aggradation over a significant portion of a reach. c. Substrate and Sediment Transport There should be an absence of any significant trend in the aggradational or depositional potential of the channel. d. Hydraulics All stream channels will maintain an ordinary high water mark (OHWM) through monitoring. A minimum of four bankfull events must be documented within the 7 year monitoring period. The four bankfull events shall occur within separate years. e. Headwater Stream Restoration Headwater stream restoration success criteria is anticipated to include documentation of surface water flow for a minimum of 30 days during the monitoring timeframe. It is anticipated that monitoring years 1 through 4 will document concentrated flow within the restored headwater valley. Additionally, monitoring years 5 through 7 will document both evidence of concentrated flow and the development of a stream bed and bank (i.e. Ordinary High Water Mark). f. Macroinvertebrate and Water Quality The provider will coordinate with resource agencies to determine if site specific monitoring protocols and success criteria for the Site are required. 2. Wetland Hydrology Hydroperiods of restored wetlands will be established in the Mitigation Plan and will be consistent with the Wetland Threshold Saturation ranges identified in the Wilmington District Stream and Wetland Compensatory Mitigation Guidance (October 2016). Groundwater and shallow surface water elevations will be collected daily during the growing season via automated gauges and downloaded quarterly. The project team will prepare hydrographs depicting water levels Response to Request for Proposal #16-20190201 20 1 P a g e Section G. Technical Approach throughout the growing season of each monitoring year. Should wetland hydrology fail to meet success criteria as outlined in the Mitigation Plan for the Site, LMG will evaluate the potential causes of failure and provide DMS with their remediation proposal. The remediation proposal will detail corrective actions and/or maintenance actions proposed and an implementation schedule. Upon review and approval of the remediation proposal by DMS, LMG will implement the necessary corrective measures. 3. Vegetation Vegetation plots will be monitoring for 7 years, with monitoring events occurring on years 1, 2, 3, 5, and 7. A combination of permanent fixed plots and random plots will be employed to document vegetation coverage. The specific protocol for plot establishment will be consistent with the recent (October 2016) Wilmington District IRT Guidance. The performance standards require a minimum of 320 planted stems per acre surviving after year three, 260 stems per acre after year five, and 210 stems per acre after year seven. Trees should average 7 feet in height at year five and 10 feet in height at year seven. In addition, any single species can only account for up to 50% of the required number of stems within a vegetation plot. Should the performance criteria outlined above not be met during the monitoring period, a remedial action plan will be prepared that will identify corrective actions and/or maintenance actions proposed and an implementation schedule for said actions. Upon review and approval by DMS, such actions will be implemented. 4. Noxious Species Noxious species will be identified and controlled so that none become dominant or alter the desired community structure of the proposed Site. If noxious plants are identified as a problem in the proposed Site, a species -specific control plan will be prepared and provided to DMS for approval prior to implementation. All vegetation removal from the Site shall be done by mechanical means only, unless DMS has first authorized the use of herbicides or algaecides for the control of plants in or immediately adjacent to the affected areas. 5. Success Criteria Methodologies and Reporting Monitoring of the Site will be performed until success criteria are met as defined in the restoration plans and the permits. Results will be documented on an annual basis, with the associated reports submitted to DMS as evidence that goals are being achieved. The project team and DMS, in coordination with the appropriate regulatory agencies, will determine when the performance standards have been achieved at the Site. If standards are not met, project team will perform appropriate remedial activities to satisfy DMS. If the monitoring of the Site demonstrates that the Site is successful by year five and no concerns have been identified, the project team will propose to terminate monitoring of the Site and forego the monitoring requirements of years six and seven. In general, the restoration success criteria, and required remediation actions, are based on the Wilmington District Stream and Wetland Compensatory Mitigation Update (USACE et al. 2016) and the Annual Monitoring Report Format, Data Requirements, and Content Guidance (NCDMS 2017). 6. Frequency All monitoring reports will be submitted to DMS's designated representative for coordination with the appropriate regulatory agencies by December 1st of each year. The year of construction may have two submittals, one being the As -Built drawings and the second being the First Year Annual Monitoring Report. If monitoring reports indicate any deficiencies in achieving the success criteria on schedule, a remedial action plan will be included in the annual monitoring reports. The project Response to Request for Proposal #16-20190201 21 I P a g e Section G. Technical Approach team will be available to coordinate any agency site visits; both before and after restoration activities have been completed. Vegetative monitoring will be conducted between July 15t and leaf drop of each monitoring year. H. Quality Control Our quality approach is based on the Total Quality Management philosophy, which provides guidance on producing quality deliverables. Quality assurance begins with a clear understanding of the goals and objectives of the project prior to finalizing project scoping. Project team members are selected based upon qualifications considered most suitable for accomplishing identified task items. The Project Manager (PM) is responsible for establishing clear roles for team members, facilitating project schedules, and ensuring quality. The project team members are involved in the development and refinement of the final scope of work and project schedule. Quality control will be ensured for editorial content, technical validity, and overall project effectiveness. Prior to submittal of any documents, the identified quality assurance reviewer meets with the PM and reviews the document's technical merits and accuracy. The assignment of a Technical Reviewer is made by the PM. The Technical Reviewer is a senior level scientist whose background and experience avoids and minimizes issues that may have been encountered on prior projects. In addition, a peer reviewer will provide editorial comment to ensure correct spelling, grammar, formatting, and consistency in text and graphics. The project team has a strong record in providing deliverables in a timely fashion to our clients and the regulatory community. Projects are typically executed within the stated budgetary constraints. The assembled team has demonstrated ability to maintain efficiency while limiting cost overruns and providing our client with a quality product. LMG has provided deliverables to NCDEQ (NC DMS) on time and on -budget throughout the course of our work over the past 15 years. Representative QA/QC measures to be employed for the Cool Run Mitigation Site are described further below. 1. The Project Manager (Mr. Kevin Yates) will be responsible for ensuring timely submittal of project deliverables (e.g. mitigation plan, baseline monitoring document, monitoring report, etc.) and invoicing that accurately reflects contract tasks and contract percentages. In addition, CMS has direct experience in NC DMS invoicing procedures. CMS will manage the invoicing spreadsheet that will display percentage of task completed and invoiced along with cumulative invoice totals. 2. The Technical Reviewer (Mr. Christian Preziosi) and the Peer Reviewer (Ms. Kim Williams) will be responsible for the technical and editorial content of the project deliverables and will ensure that the deliverables are consistent with current NC DMS standards and templates, including the Annual Monitoring Report Template (ver. 2.0)). All mitigation work will be performed in accordance with the Wilmington District Stream and Wetland Compensatory Mitigation Update (USACE et al. 2016). 3. Task managers will be assigned for each of the major milestones of the project. Task managers will provide a minimum of monthly progress reports to the Project Manager.

Technical Approach Project Manager will assign deadlines for all tasks and sub -tasks and will maintain a gantt chart illustrating projected completion dates and percentages of tasks completed. 4. The construction management team led by Mr. Grant Lewis of AXE and Wes Fryar of LMG will work closely with the Project Manager for the selection and oversight of the contractor and for the procurement of native hardwoods suitable for site conditions. LMG and AXE will conduct a pre -construction meeting with the contractor and planting foreman to review the plans and to discuss specific construction and planting protocols. Professional scientists from LMG and AXE will be on -site during planting and construction to ensure implementation consistent with the approved mitigation plan. Planting and construction will be photo -documented. The construction management team will work closely with the monitoring task manager for the installation of permanent vegetation monitoring plots and the baseline monitoring. 5. Monitoring reports will be submitted annually to the NC DMS (by December 1 of each year). These reports will include results of vegetative monitoring and photographic documentation of site conditions. Monitoring reports will also identify any contingency measures that may need to be employed to remedy any site deficiencies. The seventh year monitoring report will include a close-out report that provides an assessment of the monitoring data collected from the entire monitoring period. The Project Manager and the monitoring task manager will attend the close-out meeting(s) and will present the final project to the IRT following all DMS closeout procedures and templates.
