(SEGi), on behalf of the US Marine Corps (USMC) - Camp Lejeune, is responding to the agencies' request for additional information to complete the USMC's application to modify the Department of the Army (DoA) Individual Permit (IP) and the Division of Water Resources' (DWR) Major Water Quality Certification (WQC) for the MARSOC facility. The requested information specifically relates to the non- compliance of the failed wetland restoration, which was required as part of the FY07 and FY08 development plan. During the 11 August, on -site meeting between yourselves and Marty Korenek (USMC Camp Lejeune Natural Resources Manager), the following was discussed: I . The on -site, pennittee responsible, warm water stream, mitigation component of the IP, for FY07 and FY08 (i.e. 87 linear feet), has been met; 2. The on -site, permittee responsible, riparian wetland, mitigation component of the IP, for FY07 and FY08 (i.e. 0.14 acre), has not been met; 3. The USACE and DWR agreed to allow the USMC to purchase credits, through the Greater Sandy Run Area Mitigation Bank (GSRAMB), at a 1:1 ratio, which would be sufficient to offset the riparian wetland restoration deficiency; and 4. The USMC will submit a letter of resolution to the USACE and DWR. In total, 0.14 acre of riparian wetland restoration was to be successfully completed, in order to offset the impact of 0.14 acre of riparian wetlands associated with the MARSOC FY07 and FY08 development plan. To date, and based upon SEGi's delineation and subsequent USACE verification of the north and south riparian wetland restoration sites, 0.12 acre of riparian wetland restoration has successfully taken place within the north mitigation site (see Attachment 1 - Wetland Delineation Sketch Marine Corps Base Camp Lejeune MARSOC - North Mitigation Site), while virtually no restoration has taken place within the south mitigation. The table below denotes the proposed mitigation for the north and south mitigation sites, the as -built acreages and the difference between the two: Site Proposed (AC) As -Built (AC) A (AC) North 0.10 0.12 0.02 South 0.04 0.0 (0.04) Total 0.14 0.12 (0.02) Table 1. Mitigation Proposed vs. As -Built Acreage for the North and South Sites Note "( )" denote a deficit According to the MARSOC On -Site Wetland Monitoring Plan, the riparian wetland restoration success criteria are defined as follows: 1. Achieve a dominance of wetland hydrology, as indicated by the evidence of overbank flooding; 2. Achieve a dominance of hydrophytic vegetation, defined as a vegetation community where more than 50% of all dominant species are facultative (FAC) or wetter, excluding FAC- plants. 3. Achieve a dominance of hydric soils, as indicated by the evidence of hydric soils within select soil profiles. SEGi has performed monitoring of the north and south mitigation sites, for the past five years. Since the commencement of the monitoring (December 2010), the south side of the south mitigation site lacked indications of hydrology. The 2011 monitoring event revealed hydrology was still lacking, with very little shrub species mortality. It was anticipated, as the site matured, groundwater flow and precipitation would illicit the development of an acceptable hydrologic regime for this side of the site. However, this was not the case, as is evident in the lack of any indication of hydrology, during your last field inspection. For your convenience, copies of the 2010 through 2014 monitoring reports have been attached to this correspondence as Attachment 2. Therefore, the USMC is proposing to purchase 0.02 acre of riparian wetland restoration credit from the GSRAMB, to offset the 0.02 acre of failed restoration area. Should the agencies accept this proposal, cumulative mitigation for the FY07 and FY08, as well as the previously authorized and proposed impacts associated with the connector road, would be as follows: Phase FY07 & FY08 Connector Rd. Fulfilled On -site Wetland Restoration (AC) 0.12 Fulfilled Riparian Wetland Restoration Credit (AC) 0.0 0.13 Proposed Riparian Wetland Restoration Credit (AC) 0.02 0.09 Fulfilled On -site Stream Restoration (LF) 87 It is Table 2 Cumulative Compensatory Mitigation for Phases FY07 & FY08 and the Connector Road Total per Phase (AC / LF) 0.14 /87 0.22 It is SEGI's hope that the information found within and attached to this correspondence will satisfy the agencies' request for a solution to the issue of non - compliance, as it relates to the failed wetland restoration at the south mitigation site and the stabilization of the drainage features along the MARSOC Connector Road. However, if there are either questions, concerns or a need for additional information, please feel free to call me at 910.452.2711. Thank you in advance for your time and assistance with this project.

Project History and Current Status A. Permitting MARSOC was issued a provisional permit on 9 October 2007, which preliminarily authorized the discharge of fill material into an estimated 12.5 acres (Ac.) of wetlands and 12,800 linear feet (LF) of unnamed tributaries to Stone Bay, which abuts the New River, a navigable water of the U.S. These calculations were based upon the best information available during the preparation of the conceptual layout of the complex. During the permit process, it became necessary to separate the project into three phases: Phase I — Headquarters; Phase II — Road Realignment; and Phase III — Y07 -Y08 Development. Under these three permits, more specifically the IP dated 16 October 2008, the Applicant was authorized to permanently discharge fill into 4.36 Ac. of wetlands and 3,040 LF of tributaries. On 2 August 2010, the United States Army Corps of Engineers ( USACE) modified the individual permit to ensure accurate accounting of all impacts associated with the MARSOC project. Cumulatively the project impacted 4.34 acres of wetland and 1,447 linear feet of tributary. B. Mitigation To compensate for the impacts, the Applicant was required to make payment to the North Carolina Ecosystem Enhancement Program (NCEEP) for 2,166 linear feet of warm water stream restoration and 0.47 acre of non - riparian wetland restoration credit, as well as the restoration of 87 linear feet of stream and 0.14 acre of riparian wetland, located within the MARSOC project site. As part of the on -site stream and riparian wetland restoration, the Applicant is required to submit initial planting response reports and annual monitoring reports for both mitigation areas, to take place for a period of five years. The first annual monitoring report for the North Mitigation Site was submitted to the Corps and North Carolina Division of Water Quality (NCDWQ) on 23 December 2009, by Spangler Environmental, Inc. This report did not contain any specific vegetative monitoring data or permanent photographic station details. Within this report you will find the initial planting response for the South Mitigation Site and the annual monitoring report for both areas, with details regarding locations of permanent plots and photographic stations. H. Mitigation Site Details The goal of the project is to provide compensatory in -kind mitigation to offset unavoidable wetland and stream impacts necessary to facilitate the construction of the MARSOC project. III. North and South Site Mitigation Success Criteria For success criteria, please reference the MARSOC On -Site Wetland Monitoring Plan, submitted to the USACE on 25 March 2008. IV. Monitoring Data Two 0.01 acre (11.8' radius) circular vegetation monitoring plots were established at each of the two on -site mitigation sites (North Site and South Site). The plots were established on both sides of the channel. The center points of the monitoring sites were marked in the field by PVC tubing. All woody vegetation was counted, both o 1 o -oo 1.o 1 MAK50C Monitoring Ke -port SEG► planted and naturally recruited. Quantitative assessment of herbaceous cover was also assessed, as was species diversity. A. North Mitigation Site This site was monitored by Spangler Environmental, Inc. and a monitoring report was submitted to the USACE on 23 December 2009. According to the report, because of stabilization repairs and replanting in these areas, no specific vegetative or soils data were collected during the 2009 monitoring. Therefore, permanent data plots were established during the 2010 monitoring (see Figure 1 — North Mitigation Site). The 2010 monitoring and all future monitoring will utilize the photographic locations, shown in the Spangler Environmental, Inc., 6 October 2009 submission of the Completion of North Mitigation Area Sediment Repair/Restoration report (see Appendix A — North Mitigation Site Photographs).

There is an estimated coverage of approximately 50 percent of the ground surface by hydrophytic vegetation. The dominant vegetation in this plot includes beak rushes (Rhyncospora spp.), little blue stem (Schizachyrium scoparium), and caric sedge (Carex spp.). There is also a large number of loblolly pine (Pinus taeda) seedlings present in this plot and across the site. They cover approximately 5 percent of the plot area. They are very small in size, due to the wetness of the area. There are several stems of naturally recruited wax myrtle (Morella cerifera) that were noted within the plot area. A hand auger was used to dig a soil pit in this plot to inspect the hydrologic condition of the soil, and to allow evaluation of the boring hole for the presence of water. The soil profile revealed a dominance of hydric soil colors near the surface, but from 5 inches and deeper, an orange soil color, more suited to uplands, was dominant. This could be attributed to the fact that during the restoration of the road crossing, brighter chroma soils, found deeper in the wetland soil profile, were now near the surface. Over time, this layer may develop more characteristics of a wetland soil profile. The plot area had a shallow surface water presence, of approximately 0.5 inch in depth. The water table was at the surface, in the boring hole. No odor was detected in the soil, but there was evidence of water stained leaves. No other hydrologic indicators were noted. The area appears to be stable. Several sections of silt fence, which can be seen in the Spangler photos, have been recently removed, and the soil appears to be stabilizing well. The stream channel through the site is stable, with no visible evidence of heavy erosion or scouring of the banks or channel. The banks are almost entirely vegetated. Judging by bent vegetation inside the banks, there is evidence of high flow events in the channel, but no evidence of over bank flooding could be found. o 1 o -oo 1.o 1 MAK50C Monitoring Report Plot #2: East side of creek Lat. /Long.: N34.5864 W77.4429 Table 2: Plot #2 summary ofplanted vegetation Common Name Scientific Name Willow oak Sweetbay magnolia Quercus phellos Magnolia virginiana Total # of plants 1 5E-Gi This plot is much more densely vegetated by natural recruitment vegetation than Plot 1.

The dominant vegetation in this plot includes broomsedge (Andropogon virginiana), wool grass (Scirpus cyperinus), soft rush (Juncos effuses), beak rushes (Rhyncospora spp.), caric sedge (Carex spp.), and dog fennel (Eupatorium capillifolium). There is also a large number of loblolly pine (Pinus taeda) seedlings present in this plot and across the site. They cover approximately 70 percent of the plot area, and are larger than in Plot 1. This site is drier, in comparison, to Plot 1. There are also stems of naturally recruited wax myrtle (Morella cerifera), groundsel tree (Baccharis halimifolia), and sweetgum (Liquidambar styraciflua) noted within the plot area. A hand auger was used to dig a soil pit in this plot to inspect the hydrologic condition of the soil, and to allow evaluation of the boring hole for the presence of water. The soil profile in this plot was dominated by low chroma 2.5Y sandy clay loam soils. The upper 6 inches had many 7.5YR 5/8 mottles, with a reduction to few 7.5YR 5/8 mottles 6 inches and deeper. The presence of sandy clay loam soils can be attributed to the fact that during the restoration of the road crossing, soils found deeper in the wetland soil profile are now near the surface on account of excavation of the upper horizons. There was saturation on the surface of the ground, but no water was observed in the boring hole within 12 inches of the surface. The perched surface water could be attributed to the clay layer at the surface. No odor was detected in the soil, but water stained leaves were observed. No other hydrologic indicators were noted. There may be a need to control the quantity of loblolly pines and sweetgum in the upcoming growing season. B. South Mitigation Site For this monitoring site, please reference Figure 2 — South Mitigation Site and Appendix B — South Mitigation Site Photographs.

There were several substitutions to the approved plant list. The plants that were replaced included coastal doghobble, American holly, sweetbay magnolia, fetterbush, and switch cane. The substitutions were wax myrtle, pepperbush, red chokeberry, and broom sedge. The plants were planted generally according to hydrologic preference. The plants, although having just entered winter dormancy, appear healthy and viable, showing strong buds with no obvious dieback.

A hand auger was used to dig a soil pit in this plot to inspect the hydrologic condition of the soil, and to allow evaluation of the boring hole for the presence of water. The soil profile revealed a wide array of colors and textures, most likely caused by the recent disturbance of the area from final grading. The first 2 inches consisted of low chroma fine sandy loam, underlain by another 2 inches of high chroma sandy clay loam. Under this layer are 2 more inches of low chroma fine sandy loam, underlain by low chroma sandy clay loam down to 14 inches and greater. Beginning at 10 inches from the surface, there was capillary fringe noted in the soil, but no free water in the boring hole. Few redoximorphic features were noted within 6 -8 inches from the surface, but may be due to recent disturbance of the soil. No other hydrologic indicators were noted. The site appears to be stable. The stream channel is stable with no visible evidence of heavy erosion or scouring of the banks or channel. The banks are almost entirely vegetated.

Other hydrologic indicators noted were water stained leaves, and drift deposits. No other hydrologic indicators were noted. C. North and South Rifle Range Road Creek Crossings The north and south creek crossing slopes and channels of Rifle Range Road have been attended to, due to the instability of portions of the slopes and sediment movement in the channels. These creeks have been routinely monitored one year. To date, work to stabilize the banks has included planting of herbaceous wetland plants and woody shrubs and trees along the slopes of the channels directly adjacent to the road crossings, paying special attention to sloughing areas of soil. These eroding areas will continue to be watched, and planting will take place, as discussed, during our 30 November 2010 field meeting with the USACE and NCDWQ. One foot tall concrete weirs have been installed on both ends of each culvert at each crossing to allow sediment buildup within the culverts (see Appendix C - North and South Rifle Range Road Culvert Weir Photographs).

Impact Area PI Impact Area P1 was inspected during our 30 November field meeting with the USACE and DWQ. An area of sedimentation was noted in this area, and has since been removed. G. Sedimentation Impacts All other temporary impacts mentioned in the accepted USACE Permit Modification section 3 dated 30 August 2010 have been addressed. There areas have become stable and are showing strong and appropriate natural regrowth by native vegetation. V. Data Summary A. North and South Mitigation Sites The North Mitigation site appears overall healthy and stable, and moving towards a successful mitigation site. Data from the two data plots reveal several issues worth noting. At this time, Plot 1 shows adequate numbers of planted species per acre. However, species diversity in Plot 1 is lower than the target success criteria. Natural recruitment appears to be helping in this regard, and it may meet the criteria in the next monitoring period. While the viability and diversity of woody planted vegetation in Plot 2 is low, overall coverage and diversity is high. Supplemental planting on both sides of the creek may be necessary to satisfy the Corps requirement for number of trees per acre. Dog fennel appears to be a possible threat to the east side of the creek, as they outcompete and shade out smaller trees and shrubs, and could become widespread and dominant, if not controlled. Sweetgum seedlings could also pose a threat of becoming too dense and overtaking the area. The success criterion for hydrology is currently being met at this site. The soils are marginally hydric at this time, but will develop more prominent hydric soils characteristics as the site matures, based on the hydrologic regime observed at this site. The South Mitigation Site has been planted for two months. The vegetation has responded well to planting. The north half of the site has met the success criteria for hydrology. The south bank of the site is not currently meeting the success criteria. Hopefully, the surface and groundwater regime will develop favorably in this area as the soils settle and the site matures. The soils within the South Site appear to satisfy the hydric soil criteria. B. North and South Rifle Range Road Creek Crossings The north and south creek crossings, at Rifle Range Road, will continue to be inspected periodically for stability. Prior to undertaking any work in these areas, such as to maintain or repair either creek, as well as any supplemental plantings of these areas, Corps and NCDWQ personnel will be notified. V1. Conclusions The second annual monitoring for the North Mitigation Site, the initial vegetative response and first annual monitoring for the South Mitigation Site, located at MARSOC, United States Marine Corps Base — Camp o t o-oo 1.o 1 MAK50C Monitonng Kcport Lejeune, were performed on 22 December 2010. This site's monitoring data shows the west side to be exhibiting coverage by woody vegetation with sufficient stem numbers, but inadequate diversity of planted species. The North Site has good coverage by volunteer native herbs and woody vegetation. Because of marginally hydric soil colors, resulting from construction of the site, the soils composition is still developing to meet the hydric soil parameter. After removal of the roadbed and culvert, soils were excavated into horizons of the soil with high chroma colors, and as the site matures, the soils may begin to show natural evidence of hydric soil formation after repeated and sustained hydrologic influence. The North Site is satisfying the parameters for wetland hydrology through ponding, presence of a high water table, and presence of water stained leaves. The South Mitigation Site was planted October 2010. The initial vegetative response monitoring shows that the plants are responding well to planting and no dead or dying plants were observed. The site is satisfying the hydrologic parameter on the north side of the creek, as evidenced by indications of overbank flooding and water stained leaves, noted during monitoring. The soils within the South Site appear to satisfy the hydric soil criteria. However, the south bank is lacking any of the indicators of hydrology. As the site matures, hopefully groundwater sheet flow and precipitation from rainfall will illicit the development of an acceptable hydrologic regime for this side of the site. o 1 o oo 1 o 1 MAR50C.

Project History and Current Status A. Permitting MARSOC was issued a provisional permit on 9 October 2007, which preliminarily authorized the discharge of fill material into an estimated 12.5 acres (Ac.) of wetlands and 12,800 linear feet (LF) of unnamed tributaries to Stone Bay, which abuts the New River, a navigable water of the U.S. These calculations were based upon the best information available during the preparation of the conceptual layout of the complex. During the permit process, it became necessary to separate the project into three phases: Phase I — Headquarters; Phase 11 — Road Realignment; and Phase III — Y07 -Y08 Development. Under these three pennits, more specifically the IP dated 16 October 2008, the Applicant was authorized to permanently discharge fill into 4.36 Ac. of wetlands and 3,040 LF of tributaries. On 2 August 2010, the United States Army Corps of Engineers ( USACE) modified the individual permit to ensure accurate accounting of all impacts associated with the MARSOC project. Cumulatively the project impacted 4.34 acres of wetland and 1,447 linear feet of tributary. B. Mitigation To compensate for the impacts, the Applicant was required to make payment to the North Carolina Ecosystem Enhancement Program (NCEEP) for 2,166 linear feet of warm water stream restoration and 0.47 acre of non - riparian wetland restoration credit, as well as the restoration of 87 linear feet of stream and 0.14 acre of riparian wetland, located within the MARSOC project site. These sites are referred to herein as the North and South Mitigation sites. As part of the on -site stream and riparian wetland restoration, the Applicant is required to submit initial planting response reports and annual monitoring reports for both mitigation areas, to take place for a period of five years. The first annual monitoring report for the North Mitigation Site was submitted to the Corps and North Carolina Division of Water Quality (NCDWQ) on 23 December 2009, by Spangler Environmental, Inc. This report did not contain any specific vegetative monitoring data or permanent photographic station details. Within this report you will find the annual monitoring report for both the North and South Mitigation sites, with details regarding locations of permanent plots and photographic stations, as well as updates on select impact areas within the project. H. Mitigation Site Details The goal of the project is to provide compensatory in -kind mitigation to offset unavoidable wetland and stream impacts necessary to facilitate the construction of the MARSOC project. III. North and South Site Mitigation Success Criteria For success criteria, please reference the MARSOC On -Site Wetland Monitoring Plan, submitted to the USACE on 25 March 2008. IV. Monitoring Data Two 0.01 acre (11.8' radius) circular vegetation monitoring plots were established at each of the two on -site mitigation sites (North Site and South Site). The plots were established on both sides of the channel. The center points of the monitoring sites were marked in the field by PVC tubing. All woody vegetation was counted, both planted and naturally recruited. Quantitative assessment of herbaceous cover was also assessed, as was species diversity. o 10-00 1.o 1 MAK50C Monitaring Kerort A. North Mitigation Site This 0.10 -acre site was monitored by Spangler Environmental, Inc. and a monitoring report was submitted to the USACE on 23 December 2009. According to the report, because of stabilization repairs and replanting in these areas, no specific vegetative or soils data were collected during the 2009 monitoring. Therefore, permanent data plots were established during the 2010 monitoring (see Figure 1 — North Mitigation Site). The 2010 monitoring and all future monitoring will utilize the photographic locations, shown in the Spangler Environmental, Inc., 6 October 2009 submission of the Completion of North Mitigation Area Sediment Repair/Restoration report (see Appendix A —North Mitigation Site Photographs).

The willow oaks are showing only basal growth. There is a mix of hydrophytic vegetation that has colonized this plot. There is an estimated coverage of approximately 60 percent of the ground surface by hydrophytic vegetation. The site was seeded in the spring of 2011 with a'wetland seed mix to increase the diversity and ground coverage in this area. There is a large number of what appears to be either black eyed susan (Rudbeckia hirta) or coreopsis ( Coreopsis areolata). The dominant herbaceous vegetation in this plot includes beak rushes (Rhyncospora spp.), little blue stem (Schizachyrium scoparium), caric sedge (Carex spp.), and yellow eyed grass (Xyris spp.). A hand auger was used to dig a soil pit in this plot to inspect the profile and hydrologic condition of the soil, and to check the depth of the shallow water table. The soil profile revealed 2 inches of 10YR 2/1 sand. From about 2 inches and deeper, the dominant soil color was 70% IOYR 6/3 loamy sand with 30% IOYR 6/8 mottles. The shallow water table was observed at a depth of 6 inches, with saturation noted at about 4 inches. No odor was detected in the soil, but there was evidence of water stained leaves. The area continues to maintain overall stability. There are two very large pine trees that have fallen into the site from the northwest edge as a result of Hurricane Irene. They don't appear to have killed any of the planted trees, and the needles have browned out, and should fall soon. Light should infiltrate the limbs come spring. The stream channel through the site is stable, with no visible evidence of heavy erosion or scouring of the banks or channel. The banks are almost entirely vegetated. Judging by bent vegetation inside the banks, there is evidence of high flow events in the channel, with overbank flooding likely. o I o-oo I .o 1 MAR50C Monitoring Report Plot #2: East side of creek Lat. /Long.: N34.5864 W77.4429 Table 3: Plot #2 summary of planted trees and shrubs "41`RK °'Common Namesr`, ~;5`cientificNarrie °a ; =-k.# ofy' lant'si2U:10: #of 1_an_ ts201'ljr �:�.���.�,_�. -. ,__rs , �._��,,...__,_.� .,._, r �_ ��_- Kw,. ,�_�s.,�.._,,..- �,_�>�- �._,�.�. � >zyw,.a.P Sweetbay magnolia Magnolia virginiana 1 1 Willow oak Quercus phellos 1 3* Total 2 4 Sr-Gi *Stems were missed in 2010 monitoring event.

A hand auger was used to dig a soil pit in this plot to inspect the profile and hydrologic condition of the soil, and to check the depth of the shallow water table. The soil profile in this plot was characteristic of a wetland soil profile, with low chroma sand for the first several inches of the soil surface, with the color 10YR 2/1, and 10YR 6/1 sandy clay loam to a depth greater than 12 inches. No water was observed in the bore hole within 12 inches of the surface. B. South Mitigation Site For this 0.04 -acre monitoring site, please reference Appendix B — South Mitigation Site Photographs and Figure 2 — South Mitigation Site. The log cross vane shown on the attached site plan (see Figure 2 — South Mitigation Site) was not installed. The USACE and DWQ concurred that this structure was unnecessary in this stream system during our field meeting on 30 November 2010.

The titi may not be suited to this soil type as saplings. Older specimens may fare better. The sweetspire may have died off from lack of hydrology. According to the U.S. Drought Monitor website ( htto:// drouahtnionitor .unl.edu /arcliive.html), Southeastern North Carolina suffered a period of extreme drought conditions during this past summer, from early July, to late August, which may have attributed to the die - off. The other plants appear healthy, and thriving. There is 100 percent groundcover by herbaceous vegetation, consisting mainly of the stabilizing seed mix planted during the initial planting period. There is almost no colonization from native wetland species to date. A hand auger was used to dig a soil pit in this plot to inspect the hydrologic condition of the soil, and to allow evaluation of the boring hole for the presence of water. The first 3 inches consisted of 80% l OYR 3/1 sandy loam with 20% 10YR 4/2 mottled loamy sand down to greater than 12 inches. No water table was noted within 12 inches of the soil surface. From observation of bent vegetation inside the banks, there is evidence of high flow events in the channel, and some evidence of flooding on the north bank of the creek. The stream channel has evolved somewhat, with scour of the south bank observed. This most likely occurred as a result of heavy rains from Hurricane Irene.

The upper 12 inches consisted of 80% 10YR 3/1 sandy loam with 20% IOYR 4/2 mottles. Saturation was noted at about 12 inches from the surface. Other hydrologic indicators noted were water stained leaves and drift deposits. C. North and South Rifle Range Road Creek Crossings The north and south creek crossing slopes and channels of Rifle Range Road have remained stable since last monitoring. The herbaceous planting have thrived on both the banks and within the channels (see Appendix C — North and South Crossing Photographs). The planted trees and shrubs placed along the banks appear to be healthy and growing. The concrete weirs have helped to slow down water, and have managed to capture sediment within the culverts. The log vains placed within the upstream section of the south crossing were taken down to one log high, and are stable. There is only minor bank sloughing observed upstream of the south crossing. All old areas of sloughing have stabilized. There is excellent herbaceous colonization within both stream channels, and consists of various sedges, duck potato (Sagittaria latifolia), and rattle box (Ludwigia spp.). D. Impact Area QQ Impact Area QQ has been stabilized and planted with herbaceous and woody wetland vegetation. The base of the slopes surrounding the wetland area is being monitored routinely to determine if rock or wetland plants will be needed. The planted vegetation is thriving. No die -off has been observed in any of the planted specimens. The areas of open soil around the edges were seeded with a wetland seed mix in the spring, and several coreopsis were observed during the summer. The bases of the slopes are currently stable. As the slopes are well established, no change to this area is expected over the next season. E. Impact Area DI Impact Area Dl has been planted with wetland trees and shrubs including willow oak and wax myrtle. The ground surface is stabilized by centipede grass sod. F. Impact Area Pl Impact Area PI has been routinely monitored throughout the year, and has remained stable throughout the growing season. V. Data Summary A. North and South Mitigation Sites The North Mitigation site appears overall healthy and stable, and moving towards a successful mitigation site. Plot 1 shows adequate numbers of planted species per acre. There has been a strong recruitment by native hydrophytic vegetation, which should ensure that the site meets the vegetative criteria at the end of the required monitoring period. While the diversity of woody planted vegetation in Plot 2 is low, overall coverage and diversity on the east side of the creek is high. Supplemental planting on both sides of the creek may be necessary to satisfy the Corps requirement for number of planted trees per acre. Natural recruitment of sweetgum seedlings seems to have stopped. As these trees mature, thinning of the numbers should take care of dominance within the mitigation area. The success criterion for hydrology is currently being met at the North Mitigation site. The soils are marginally hydric at this time, but will develop more prominent hydric soils characteristics as the site matures, based on the hydrologic regime observed at this site. o 10-00 1.o i MAK50C Monitoring }wort SEGi The South Mitigation Site appears to be stable. There has been a die -off of several of the planted shrubs. The site is still meeting the required trees per acre requirement of the mitigation plan. The north half of the site has met the success criteria for hydrology. The south bank of the site is not currently meeting the success criteria. Hopefully, the surface and groundwater regime will develop favorably in this area as the soils settle and the site matures. The soils within the South Site appear to satisfy the hydric soil criteria. B. North and South Rifle Range Road Creek Crossings The north and south creek crossings, at Rifle Range Road, will continue to be inspected periodically for stability. All slopes and channels have stabilized, aside from one area of bank sloughing upstream of the south crossing. The hydrophytic trees, shrubs, and herbaceous vegetation that were planted at these locations in the spring of 2011 have adapted well to planting, and are thriving. There is good natural recruitment of native hydrophytic herbaceous vegetation at both locations. VI. Conclusions The third annual monitoring for the North Mitigation Site and second annual monitoring for the South Mitigation Site, located at MARSOC, United States Marine Corps Base — Camp Lejeune, were performed on 21 December 2011. The North Mitigation Site's monitoring data shows the site to be exhibiting coverage by woody vegetation with sufficient stem numbers, but inadequate diversity of planted species. The North Mitigation Site has good coverage by volunteer native herbs and woody vegetation. Because of marginally hydric soil colors, resulting from construction of the site, the soils composition is still developing to meet the hydric soil parameter. After removal of the roadbed and culvert, soils were excavated into horizons of the soil with high chroma colors, and as the site matures, the soils may begin to show natural evidence of hydric soil formation after repeated and sustained hydrologic influence. The North Mitigation Site is satisfying the parameters for wetland hydrology through ponding, presence of a high water table, and presence of water stained leaves. The South Mitigation Site's monitoring data show partial success of the site to date. There was a small die -off of planted shrubs, but overall, the plants are thriving. The site is satisfying the hydrologic parameter on the north side of the creek, as evidenced by indications of overbank flooding and water stained leaves, noted during monitoring. The soils within the South Site appear to satisfy the hydric soil criteria. However, the south bank is lacking any of the indicators of hydrology. As the site matures, hopefully groundwater sheet flow and precipitation from rainfall will illicit the development of an acceptable hydrologic regime for this side of the site. The North and South Crossings, and Impact Areas QQ, Dl, and P1 are currently stable and could be considered successfully restored. All planted vegetation is thriving, and slopes and channels are overall stable. o 10-00 i o 1 MAK50C Monitoring Report Appendix A North Mitigation Site Photographs SE-6i 12/21/2011 MARSOC - North Mitigation Site Photo Point 1: Facing south 12/21/2011 MARSOC - North Mitigation Site Photo Point 2: Facing west -.ems fur:;,� • k ^ ,i, 12/21/2011 MARSOC - North Mitigation Site Photo Point 1: Facing south 12/21/2011 MARSOC - North Mitigation Site Photo Point 2: Facing west 12/21/2011 MARSOC - North Mitigation Site Photo Point 3: Facing south 12/21/2011 MARSOC - North Mitigation Site Photo Point 4: Facing north _,. .• 1 .`�f�M"�`a� %r' � �wr �� _ t'�'+k ±�xr� iJ,l �_ ^.} _ � f �, i � K �Lyr F;iR 3'. _`�1� �_Y�1e IeFI�� '�,.',• _ § +4 '1 7'7'� � )> '4 f :. ,� .
