Alan Fickett and Bill Gurber ECOBANK 5104 N. Orange Blossom Trail, Suite 210 Orlando, Florida 32810 Dear Sirs: grr?'gwq OCT 0 4 2005 WETLANDS AND TORPAWATER BRANCH This letter confirms the final review of the Wetland Mitigation Plan for Barra Farms Phase II Mitigation Bank, owned by Ecosystems Land Mitigation Bank Corporation (ECOBANK), located at the intersection between Highway 53 and Highway 210, north of SR 2041 (Beard Road), in Harrison Creek Bay, in the headwaters-of Harrison Creek, near Cedar Creek, Cumberland County in the lower Cape Fear River Drainage Basin, North Carolina. Also, please reference my August 25, 2005 telephone conversation with Mr. Rob Moul of Land Management Group, and my November 22, 2004 meeting with Mr. Christian Preziosi of Land Management Group. As stated in the December 1998 Mitigation Banking Instrument (MBI) for Barra Farms Mitigation Bank Phase I, the sponsor may request the addition of adjacent lands to the Phase I bank site provided specific provisions are addressed, including a site-specific restoration plan. A restoration plan was submitted to our office and circulated to the Mitigation Bank Review Team (MBRT). Upon our review and coordination with the MBRT, our office concurs with the December 2004 Wetland Mitigation Plan, or site-specific restoration plan, which includes credit types, amounts, and credit release schedule. This plan includes the restoration, enhancement, and preservation of 1,812 acres of wetlands and waters. Our office agrees to the proposal of sectioning Phase II into three parts: Section I of Phase II is 1,171 acres (or 512 credits), Section II of Phase II is 335 acres or (328 credits), and Section III of Phase II is 306 acres, or 299 credits. These sections of Phase II will be implemented sequentially. All provisions of the MBI shall apply to Phase II of the bank. Therefore, you are reminded that prior to any release of credits for Section I of Phase II, and for each following section, the following must be completed prior to the release of any credits: 1) ownership documentation of the property, including title search, 2) delivery of acceptable financial assurances, 3) recordation of an acceptable preservation mechanism acceptable to the Corps, as well as title opinion covering the property acceptable to the Corps, and 4) an acceptable construction schedule. Once these items have been completed, a copy of,the documents must be provided to our office -2- for confirmation. This step must also be repeated for both Section II & III prior to the release of any credits in those sections. At any time there are failures in Section I, the MBRT retains the right to modify the restoration plan for Section II & III in order to ensure the success of Phase II. Upon receipt and approval of the items 1-4 above, fifteen percent (15%) of the bank's total credits for Section I of Phase II shall be immediately available for sale. Please be reminded that you must also complete the initial physical and biological improvements to the bank site pursuant to the mitigation plan no later than the first full growing season following initial debiting of the Bank. . In regards to Barra Farms Phase I, our office has some concerns regarding the accounting procedures, property disposition, and long-term management. Pursuant to the December 1998 MBI in Section 4.4 Accounting Procedures, you are required to generate a report, within 30 days of debiting credits, showing the credits used at the time they are debited from the bank; and to prepare an annual debit or credit report on each anniversary of the date the MBI was executed, which is March 5, 1999. To date, we have no record of any credits being debited from Phase I. Additionally, the MBI states that you intend to provide fee simple transfer of the property to the appropriate land management organization as determined by the MBRT. The mitigation plan states that the North Carolina Wetlands Restoration Program intends to hold the easement in the interim until completion of debiting of the bank, or until the end of the monitoring period, whichever is longer. In discussions with your office and Land Management Group, it is our understanding that you were in negotiations with the Sandhills Area Land Trust (SALT) to hold the easement and manage the property in perpetuity. Again, at this time, our office has no record of the fee simple transfer agreement. Lastly, our office has concerns and questions over the long-term management of Phase I. The MBI states that you will provide a separate, long-term trust fund for the long-term maintenance, management, and remedial actions acceptable to the MBRT. We have been informed that EcoBank has experienced some financial difficulties; and our office is concerned that this will affect or compromise the long-term management of the site. If this is valid, please provide us with assurances of EcoBank's ability to move forward with the long-term management plan. We are pleased at the results of success during the five-year monitoring period, but question the long-term management status. Please provide a status report regarding the required trust fund. If all credits have been debited, you must. satisfy the long-term trust fund immediately. With the absence of the above information, our office and the MBRT members will look unfavorably upon the release of future credits in Phase II. -3- As always, future decisions concerning the acceptability of the use of this bank to offset the wetlands impacts authorized by any particular permit will be made during the review of that permit. If you have any questions or comments on this issue, please contact me at (910) 251- 4811, if you have any questions.

Prints SIGNED: SUPPLEMENTAL ACTIONS TAKEN AT BARRA FARMS CAPE FEAR REGIONAL MITIGATION BANK 1999-2000 The following is a list of actions that have been taken to improve the quality of monitoring and insure future mitigation success at Barra Farms: 1. Installation of six 18" diameter drainage pipes along the north section of Barra to alleviate ponding (Figure 1). The pipes were installed in October of 1999 to reduce the standing water created by rainfall from hurricanes and from any future heavy rain events. Ponded water will be lowered only during and/or after extreme climatic rainfall events after which ponding could be detrimental to the growth of survival of character species. The pipes will not allow groundwater levels to recede below the wetland hydrology thresholds and can be plugged in dry periods to allow percolation into the wetland before standing water is released. 2. The percentage of Barra being sampled for vegetation was increased in Year 2 monitoring. In Year 1 monitoring, 24 plots, each 0.05 acre in size, were sampled resulting in a total of 1.2 acres surveyed. In order to get a larger sample of representative vegetation and to pinpoint the location of areas not meeting the vegetative success criteria, the sampling area was increased in 1999. In Year 2 monitoring, 34 plots that were each 0.1 acre in size were sampled resulting in 3.4 total acres surveyed. This is a 283% increase in sampling size between Year 1 and Year 2. These 34 plots include 19 of the original 24 plots plus an additional 15 plots randomly placed in areas generally lacking plots. 3. In December of 1999, a subcontractor hired by ECOBANK installed 3 new RDS monitoring wells at Barra to get a more precise and continuous account of hydrology. A total of five RDS wells now read hydrology data on-site and 2 RDS wells are located at reference sites. 4. In January of 2000, the mouth of the mitigation stream at Barra was cleaned of debris such as fallen limbs and snags to increase stream flow and further reduce standing water in this area (Figure 2). 5. Supplemental planting at the Barra Farms Mitigation Bank was performed February 8-11, 2000. Twelve species that have shown an ability to survive at Barra (Table 1) were planted across the groundwater flats and headwater slope habitats, which comprise approximately 362 acres of this site (Figure 3). Seedlings that were approximately 2 years old were purchased from the North Carolina Division of Forest Resources Nursery in Goldsboro, NC (Figure 4) and were evenly distributed across the former crop land at Barra (Figures 5 and 6). However, in wetter areas, such as the headwater slope habitat, a greater number of bald cypress and water tupelo were planted, since these species are better adapted to wet conditions. Planting actions were closely monitored by Land Management Group, Inc. personnel. A total of 43,300 seedlings planted across 362 acres resulted in approximately 120 trees/acre (- 20-foot spacing). Since an average of 241 characteristic trees/ac (average of groundwater flats and headwater slope habitats) were observed in Year 2 monitoring, this supplemental planting increased tree density to 361 trees/acre. These trees, in addition to new volunteers and the established trees already present, will help Barra achieve the vegetative success criterion of 320 characteristic trees/acre over the required monitoring period.

Since the continuous monitoring stream gauges placed in the reference and restoration streams in 1999 have been somewhat unreliable, staff gauges will be replaced and used as a backup measure of stream flow. The staff gauges will insure continuous collection of flow data and will allow a more accurate assessment of stream mitigation.

PROGRESS REPORT: Results of April, 2000 vegetation monitoring at Barra Farms Cape Fear Regional Mitigation Bank Prepared for: Ecobank Prepared by: Land Management Group, Inc. Wilmington, NC May 1, 2000 Success criteria for the Barra Farms Mitigation Plan include a minimum mean density of 320 characteristic trees/acre. At least five character tree species must be present, and no hardwood species can comprise more than 20 percent of the total number of stems/acre total. Softwood species cannot comprise more than 10 percent of the total number of stems/acre. The Year 2 Monitoring Report found that neither the groundwater flats nor headwater slope community types met these vegetation success criteria. Supplemental planting of 43,300 seedlings occurred during February of 2000 to increase survivability to acceptable levels. A third monitoring survey was conducted in April of 2000 to monitor the progress of these seedlings. The results of both surveys are given below. November, 1999 SURVEY (2' Monitoring Report) Groundwater Flats Within the groundwater flats habitat, 27 woody species were surveyed among the 29 plots. Of the 27 species, 19 were tree species and 8 were shrub species. Of the tree species, 11 were planted and 8 were volunteer. All shrubs were volunteer. Most common species included bald cypress (Taxodium distichum), black willow (Salix nigra), red maple (Acer rubrum), and swamp tupelo and/or water tupelo (Nyssa biflora, N. aquatica). The vegetation observed within groundwater flats averaged 269 stems/acre with approximately 128 stems/acre from planted species. Because 435 stems/acre were planted in these areas in the winter of 1998, the survival rate is estimated at approximately 29% after the second growing season. When using the number of trees/acre by species that can be applied to the total number of stems/acre criterion (<_ 20% of 320 stems/acre for hardwoods and _< 10% of 320 stems/acre for softwoods), the total number of trees that can be counted per acre is 255.4 (see Table 4, column 5). Headwater Slope A total of 8 woody species were found within this habitat, of which 4 were planted and 4 were volunteer. The most common species include black willow (Salix nigra), swamp tupelo and /or water tupelo (Nyssa biflora, N. aquatica), red maple (Acer rubrum), and bald cypress (Taxodium distichum). This vegetation averaged 317 stems/acre, with 130 stems/acre from planted species. Therefore, the survival rate of trees planted in the headwater slope is 30%. When success criteria percentages are used (<_ 20% of 320 stems/acre for hardwoods and <_ 10% of 320 stems/acre for softwoods), the total number of trees that can be counted per acre is 227.5 (see Table 5, column 5). April, 2000 SURVEY (3`d Monitoring Report) Groundwater Flats Within the groundwater flats habitat, 26 woody species were surveyed among the 30 plots. Of the 26 species, 18 were tree species and 8 were shrub species. Of the tree species, 11 were planted and 7 were volunteer. All shrubs were volunteer. Most common species included bald cypress (Taxodium distichum), black willow (Salix nigra), red maple (Acer rubrum), and swamp tupelo and/or water tupelo (Nyssa bflora, N. aquatica). The vegetation observed within groundwater flats averaged 485.1 stems/acre with approximately 259 stems/acre from planted species. When using the number of trees/acre by species that can be applied to the total number of stems/acre criterion (_< 20% of total stems/acre for hardwoods and s 10% of total stems/acre for softwoods), the total number of trees that can be counted per acre is 456.6 (see Table 6, column 5). Headwater Slope A total of 14 woody species were found within this habitat, of which 9 were planted and 5 were volunteer. The most common species include black willow (Salix nigra), swamp tupelo and /or water tupelo (Nyssa bflora, N. aquatica), red maple (Acer rubrum), and bald cypress (Taxodium distichum). This vegetation averaged 612.5 stems/acre, with 300 stems/acre from planted species. When success criteria percentages are used (s 20% of total stems/acre for hardwoods and _< 10% of total stems/acre for softwoods), the total number of trees that can be counted per acre is 436.2 (see Table 7, column 5). Summary In 11/99, a mean density of 255.4 stems/acre was found across 27 character wetland species within the groundwater flats habitat, with an average of 3.9 species/plot. In 4/00, a mean density of 456.6 stems/acre (adjusted) was observed across 26 character wetland species, with an average of 6.6 species/plot. In the headwater slope habitat in 11/99, a mean density of 227.5 stems/acre was found across 8 wetland species, with an average of 4 species/plot. In April, 2000 the headwater slope habitat had a mean density of 436.2 stems/acre (adjusted) across 14 wetland species, with an average of 7.5 species/plot. Both habitats doubled their stem counts as well as their species diversity. As a result of natural recruitment, supplemental planting, and the installation of drainage pipes to control water levels, both habitat types now contain more than 320 stems/acre and over 5 wetland species/plot. Therefore, the Barra Farms Mitigation Bank has met and exceeded the wetland vegetation success criterion. 2 (5 •y D\ ?O O? N ?o 00 r- tn tn M y O co O 00 N M r- W) M C?

The bank comprises 623 acres located along upper reaches of Harrison Creek in Cumberland County ' (Figure 1). Stream and wetland restoration/enhancement activities were completed in the winter of 1997-1998 as described in the detailed mitigation plan. A mitigation banking instrument has also been prepared through ongoing coordination with the mitigation banking review team (MBRT) as ' outlined in the Federal Guidance on the Establishment, Use, and Operation of Mitigation Banks (60 FR 12286-12293, 1995). ' The detailed mitigation plan and the MBI details wetland and stream monitoring procedures and success criteria required for release of compensatory mitigation credits. The monitoring plan ' requires annual monitoring for a five year period and analysis of the data to evaluate success in the establishment and maintenance of diagnostic stream and wetland parameters. The monitoring plan and mitigation credit schedule are attached for reference in Appendix A. ' This document represents the Annual Wetland Monitoring Report (AWMR) for Year 1 of the ' monitoring plan. Monitoring has been performed throughout the 1998 growing season for hydrology, vegetation, and stream parameters, consisting primarily of a comparison between hydrology model predictions, reference wetlands, and wetland restoration areas in the Bank. ' Subsequently, the success criteria are analyzed and verified to facilitate issuance of mitigation credit designated in the MBI at the end of Year 1 monitoring.

' Wetland construction was completed and the monitoring wells placed in January 1998. Figure 2 depicts the approximate location of monitoring wells in the Bank. Two continuous recording (RDS24) wells were also placed on-site to provide continuous data that can be extrapolated to ' manual recording devices. Monitoring wells were installed and downloaded by ECOBANK personnel in accordance with specifications in U.S. Corps of Engineers', Installing Monitoring Wells/Piezometers in Wetlands (WRP Technical Note HY-M-3.1, August 1993). The monitoring ' wells are set to a depth of approximately 24 inches below the soil surface. ' Five monitoring wells were placed in reference wetlands to compare hydrology between the Bank and relatively undisturbed wetlands in the region. Three wells are located in the reference groundwater flats along the northwestern periphery of Barra Farms. Two additional wells are located in the reference riverine wetland along Colly Creek in the Bushy Lake/Horse Shoe Lake Natural Area. These wells provide comparative annual hydroperiods within the organic soil flat and riverine floodplain physiographic areas of the Site. The headwater slope physiographic area will be interpolated between the two adjacent systems as described in the mitigation plan and the NMI. ' Hydrological samples continue to be collected at weekly intervals on-site and within the reference sites. The data extending from 14 March 1998 to 30 September 1998 has been utilized in this Year ' 1 AWMR, to cover the 1998 growing season. 2.2 MONITORING RESULTS ' The raw well data is depicted as hydrographs and in tabular format in Appendix B. Wetland hydrology criteria in number of consecutive days and % of the growing season is also summarized in Table 1. The water levels show a typical pattern of flooding during the early spring, followed by ' late summer and autumn dry periods. A steady linear interpolation between well readings was assumed for flooding event calculations. Line intersection at 12 inches below the surface was used ' as the cut off for wetland hydrology, following the regulatory wetland criterion requiring saturation (free water) within one foot of the soil surface. ' The well data has been subdivided into three wetland physiographic wetland types: 1) groundwater flats (GF); 2) headwater slopes (HS); and 3) riverine floodplains (SS). 0 5 1 C I C C C o co m a ? a N i O Ob 2 m iz a` o° 0 a- -, s. m m ? m 3 U ?

Groundwater Flats (GF) ' The reference wetland data provides an general indication of the average 1998 wetland hydroperiod on groundwater flats that support steady state forest structure and organic soils. Data indicates that ' the average hydroperiod on reference groundwater flats in the region encompassed 37% of the growing season and ranged from 35% to 40% dependent upon landscape position. ' The groundwater flat data indicates that the Bank supported an average wetland hydroperiod encompassing 40% of the growing season (Table 1). The hydroperiod ranged from 31% to 47% and appeared to correlate with the extent of existing vegetation cover and soil organic matter content. ' Organic soil flats on former farmland (relatively unvegetated) supported an average hydroperiod encompassing 45% of the growing season. Organic soil flats that support dense successional ' (pocosin-like) vegetation supported an average wetland hydroperiod of 38%. Mineral soil flats on former farmland in southwestern and northeastern site peripheries also exhibited hydroperiods averaging 38% of the growing season. ' Riverine Flood plains ' The reference wetland suggests that the average hydroperiod in relatively undisturbed, small stream swamps encompasses 45% of the growing season and ranges from 42% to 47% dependent upon proximity to the stream channel (Table 1). Hydroperiods appear to decrease in proximity to stream ' channels and increase along outer floodplain fringe influenced by riparian groundwater discharge, the lack of discharge outlets (stream channels), and backwater flooding. ' Riverine floodplains in the Bank supported wetland hydrology averaging 43% of the growing season and ranged from 38% to 48%. As with the reference wetlands, The primary influence on ' hydroperiod appears to involve the location of the well relative to the stream channel. Headwater Slopes ' Reference wetland hydroperiods for the headwater slope physiographic area have been simulated by averaging the hydroperiod exhibited by adjacent riverine floodplains and groundwater flats (see ' Appendix A). The average reference hydroperiod encompassed 41% of the growing season and ranged from 37% (adjacent groundwater flat) to 45% (adjacent riverine floodplain). ' Based on interpolation between flats and riverine wetland hydroperiods, headwater slopes in the Bank are projected to support wetland hydroperiods averaging 41% of the growing season and ' ranged from 33% to 45% (Table 1). The range appears to be influenced primarily by landscape position within the headwater storage area and vegetation cover. Lower hydroperiods (33%) occurred in an area dominated by early successional or pocosin vegetation (Well #W19) while hydroperiods in forest and former farmland ranged from 37% to 45%. 9 2.3 EVALUATION OF SUCCESS CRITERIA ' Hydrological success criteria are described in detail in Appendix A. In summary, success in the restoration of wetland hydrology in the Bank require saturation (free water) within one foot of the ' soil surface for at least 50% of the hydroperiod exhibited by the reference wetland. This criteria is applied separately to each of the physiographic areas. ' The reference groundwater flat, riverine floodplain, and headwater slope exhibit wetland hydrology for a period averaging 37%, 45%, and 41% of the growing season, respectively. In the Bank, restored wetlands support hydroperiods averaging 40%, 43%, and 41 %, respectively (95% to 105% of reference). ' At individual locations, the greatest deviation between reference and the Bank occurred at Well # W 14 (Figure 2 and Table 1). This groundwater flat represents a transitional area from organic soil to mineral soil proximal to a Carolina Bay sand rim. The wetland hydroperiod at Well #W14 ' encompassed 31% of the growing season or 84% of the hydroperiod exhibited by reference (37% of the growing season). Therefore, restoration of wetland hydrology has been successfully achieved ' throughout the Bank. F 10 3.0 VEGETATION MONITORING ' 3.1 MONITORING PROGRAM ' Quantitative sampling of vegetation was carried out in October 1998. Twenty-four permanent, circular sampling plots (0.05 acre) are located near the monitoring wells in the restored wetland areas. Figure 2 depicts the approximate location of each vegetation sample plot. The center of each ' plot is permanently established with a labeled, white Polyvinyl chloride (PVC) pipe. The restoration area is comprised of several community types with overlapping stages in forest t development, requiring two methods for sampling vegetation. The first method is used in former crop land and early successional scrub communities, where full tree planting (435 stems/acre) was ' implemented. The second method is used in plots where an established forest canopy is present and supplemental tree plantings occurred (70 stems/acre). Method 1: (Former Crop Land. Full Planting) In planted crop land, all woody species exceeding one inch in diameter at breast height (DBH) were recorded and measured for height and DBH within each 0.05-acre plot. In some cases, clumps of multiple black willow (Salix nigra) stems originating from a common root source were counted as single stems. Stems less than one inch in DBH were also measured for height and summed to obtain the number of stems on a per acre basis. Average heights and average DBH were collected to document future growth in Year 2 through 5 of the monitoring plan. 1 All herbaceous vegetation was recorded and assigned to one of 7 cover classes: 1=0-5%, 2=0.5-1%, 3=1-3%, 4=3-15%, 5=15-33%, 6=33-66%, 7=66-99%. Specific cover values ' were obtained by averaging the class mid-point for each species. Cover classes for all species was determined by visually estimating the area of ground surface covered by its vertical projection. ' Method 2: (Forest Areas. Supplemental Planting) h t t i suppor a ng areas t This method was used to evaluate forest stands and supplemental plant multiple vegetative strata. The vegetation profile was divided into four strata: ' Overstory - trees >4 inches DBH, ' Midstory - trees and shrubs > 1 inch and < 4 inches DBH, Understory - shrubs and herbs < 1 inch DBH. Planted Seedlings Overstory and midstory were recorded by species and DBH. Tree species density and basal area was calculated separately for the overstory and midstory. Importance values (Rank) ' 11 u were calculated from relative basal area and relative density. Planted seedlings were ' measured as described above. Cover estimates for the understory elements were estimated over the entire plot using the cover classes described above. 1 n 3.2 MONITORING RESULTS The vegetative community at Barra Farms can be separated along a succession continuum of forest development. Over half of the acreage is in the early stages of old field succession. This area extends over several different physiographic areas and received a full planting of diagnostic species at 435 trees/acre. The vegetation is dominated by volunteer herbaceous species that vary in abundance according to micro-topographical differences and seasonal variation. Hydrophytic vegetation established during the spring and early summer include sedges (Cyperus spp.), cat tail (Typha sp.), seedbox (Ludwegia spp.), knotweed (Polygonum spp.), wool-grass (Scirpus cyperinus), and yellow-eyed grass (Xyris spp.). In summer and early fall, developing herbaceous components include panicum grasses (Panicum spp.), crab grass (Digiteria sp.), horseweed (Erigeron canadensis), frost aster (Aster pilosus), and dog-fennel (Eupatorium capillifolium). Complete species inventories can be found in Appendix C. Further along the succession continuum, several fallow fields and areas along old drainage ditches support volunteer trees > 1 inch DBH, such as black willow, sweet gum (Liquidambar styraciflua), red maple (Acer rubrum), loblolly pine (Pinus taeda), and loblolly bay (Gordonia lasianthus). These areas continue to support dense areas of herbaceous species. Black willow and red maple can be aggressively invading species, creating competition for other more desirable tree species. Canopy dominance by these species in certain areas may be a concern and may warrant attention in Years 2 through 5 of the monitoring plan. However, black willow, red maple, and overtopping by herbaceous species are not posing an imminent threat to diagnostic tree species in the 1998 growing season. A detailed review concerning competition from herbaceous species should be performed in the late spring of 1999. The greatest risk of overtopping by herbaceous species and resulting tree mortality is expected if a drought occurs in early spring. Former Crop Land, Full Planting Stocking levels of planted trees and natural recruitment are summarized in Table 2. A total of 18 species, both planted and volunteer were found. The top 8 species include black willow, bald cypress (Taxodium distichum), water tupelo and/or swamp tupelo (Nyssa aquatica, Nyssa biflora), red maple, cherrybark oak (Quercus pagoda), overcup oak (Quercus lyrata), swamp cottonwood (Populus heterophylla) and willow oak (Quercus phellos). The total stocking level averages 733 stems/acre with approximately 360 stems/acre representing planted seedlings. Because 435 stems/acre were planted in the Bank, the survival rate is estimated at approximately 83% after the first growing season. A large majority of the mortality appears to have occurred in Atlantic white cedar (AWC, Chamaecyparis thyoides) seedlings; mortality is probably due to overtopping by water in early spring. The planted AWC seedlings supported negligible above ground woody stems and the above-ground plant parts resided under water during the spring and early summer. 12 .ri CCt O C Q bA O ' N ^C ,IS e?

SupRlemental Planting Table 3 depicts the stocking levels of existing trees (> 4 inches DBH) combined with planted seedlings in the forested, supplemental planting areas of the Bank. The total stocking level averages 636 stems/acre. Red maple represents the most abundant over-story species in the forest community, ' accounting for 32% of all stems encountered. Other important species include, bald cypress, loblolly bay, sweet gum, and swamp tupelo. 3.3 EVALUATION OF SUCCESS CRITERIA Success in the restoration of wetland vegetation includes the establishment and maintenance of a ' species composition sufficient for a jurisdictional determination. Additional success criteria include a minimum mean density of 320 characteristic trees/acre. At least five character tree species must be present, and no species can comprise more than 20 percent (64 stems) of the 320 stem/acre total. ' Softwood species,(ex: loblolly pine, pond pine, and black willow) cannot comprise more than 10 percent (32'stems) of the 320 stem/acre requirement. ' Table 2 and Table 3 depict the number of trees/acre by species that can be applied to the 320 stem per acre criterion (column #5). In former crop land, a mean density of 379 diagnostic stems/acre is ' represented across 17 characteristic wetland species (Table 2). In forest areas, 426 trees and planted seedlings/acre are represented across 14 diagnostic species. The 379 stem/acre (crop land) and 426 stem/acre (forest area) totals exceed the 320 stem/acre requirement stated in the monitoring plan. In addition, the 14 characteristic wetland species sampled exceeds the 5-species minimum diversity stated in the monitoring plan. Therefore, current stocking levels meet the vegetation success criteria. ' 14 1 1 ? GC A ti1D ? ? ea M ? b O ' a °o ACt a a RS ? W it CC CA 0 3 O H O U fr ,??, lr a°i V ?i V a°? •p 4? ? {r ? V ?

Two monitoring plans have been developed; the initial plan is included in the detailed mitigation plan. The updated monitoring plan is included in Appendix A and has been incorporated into the most recent draft of the MBI. ' 4.1 INITIAL MONITORING PLAN The initial monitoring plan calls for periodic measurement of stream stage and rainfall in the Bank. ' One staff gauge has been placed on central sections of the mitigation stream reach and the second staff gauge is located approximately 300 feet below outfall from the Bank. Rain gauges have been ' placed at open locations within central portions of the Bank. Stream stage and rainfall have been measured weekly throughout the monitoring period. Table 4 depicts the stream stage and rainfall data during the report period. ' The channel supported continuous flows during the spring and early summer. On June 9, stream flows were absent; however, numerous pools of standing water and saturation of the developing ' stream channel bed were observed. The cessation of stream flows corresponded closely to the period of rapid groundwater draw-down observed within groundwater flat portions of the Bank. Wetland ' hydroperiods ended within a majority of wetland monitoring wells during the week of June 3 to June 9. In addition, flows ceased within the reference stream reach during this period. On September 8, stream flows returned to the Bank and the reference reach after relatively large rainfall events in the area. ' The initial monitoring plan proposed fulfillment of success criteria if near-permanent stream flows are established within the Bank. Intermittent flow may occur during periods of groundwater draw- down, generally confined to summer months. Insufficient data has been collected to fully verify ' success criteria. However, assuming that flows continue throughout the fall and winter months of 1998/99, the channel will have supported near-permanent flows and developing in-stream aquatic ' habitat for 302 days, or 83% of the year. 4.2 UPDATED MONITORING PLAN ' The updated monitoring plan has been developed based on consultation with the MBRT to provide data sufficient to support first order stream restoration credit. The current monitoring plan, included in Appendix A, calls for measurement of in-stream flows, measurement of stream geometry, and ' measurement of biological stream attributes. 16 A °y o aio a ?

The gauge data will be reported as mean daily flows for velocity (ft/second) and discharge (CFS) in tabular and graphic format. In-stream flow measurements must indicate that the mitigation stream reach supports average annual, mean daily flows per unit of drainage area equal to, or exceeding the average annual, mean daily flows per unit of drainage area within the reference stream reach. Due to potential rainfall differences within each watershed, a five percent deviation in average annual, mean daily flows between the reference and mitigation stream reaches will be allowed by the MBRT. The reference stream reach supports an approximate 6.7 mil drainage area while the mitigation stream reach supports an approximate 2.5 mil drainage area (37% of reference). Therefore, average annual, mean daily flows in the mitigation reach must equal to or exceed 32% of the average annual, mean daily flows in reference. Stream gauges will be placed in the Bank and in the reference stream reach in early December 1998. The gauges will be downloaded and the data analyzed for the Year 2 AWMR, when sufficient stream flow data has been collected to evaluate restoration success. Therefore, release of stream credit will begin at the end of Year 2 monitoring as depicted in the revised mitigation credit release schedule in Table 5. 4.2.2 Biological Stream Attributes In the updated plan, biological stream attributes will be measured in the Bank and in reference between April 15 and May 15 of each year. Biological monitoring will be used to compare in-stream species diversity between the mitigation stream reach and the reference stream reach. Success criteria for stream restoration will require that the type and number of species populations identified in the mitigation reach must be equal to, or increasing towards, the type and number of species identified in the reference reach in each successive monitoring year. However, because the Bank has a developing stream reach, allowances may be given and justified when evaluating future data. Upon- approval of the MBI, biological surveys will be initiated in April 1999 and included in the Year 2 AWMR. 4.2.3 Stream Geometry Stream geometry will be measured in central sections of the mitigation stream reach. The reach has been staked in the field by permanent PVC pipes and markers at 25-foot intervals. The reach extends for 300 feet along the restored channel. Stream geometry measurements to be collected include a channel plan view, three channel cross-sections, pebble counts, and a water surface profile. Data compiled will include : 1) cross-sectional area; 2) bankfull width; 3) average depth; 4) average width; 5) width/depth ratio; 6) meander wavelength; 7) beltwidth; 8) water surface slope; 9) sinuosity; and 10) stream substrate composition. 19 x z as vW, z G az?

The channel and flood prone area must support characteristics supporting an E, C, or DA stream type to fulfill the success criteria. ' Baseline conditions were assessed in May 1997 to characterize the former stream channel prior to restoration activities. However, lack of regular stream flow, organic matter accumulation, and debris ' deposition obscured evidence of a defined stream channel, bankfull cross-section, or stable pattern within the Bank. Therefore, the system could not be classified based upon fluvial geomorphology (pattern, dimension, and profile). 4.3 SUMMARY ' Success criteria for stream restoration has been subdivided into three primary components: in-stream flows, stream geometry, and biological stream attributes. Insufficient data has been collected to evaluate success criteria for the Year 1 AWMR. Therefore, data will be collected and analyzed for ' the Year 2 AWMR. Release of stream credit will begin at the end of Year 2 monitoring as depicted in the revised mitigation credit release schedule in Table 5. L n 21 n 5.0 WETLAND FUNCTIONAL ATTRIBUTES AND MITIGATION CREDIT ' The following discussion provides photographic evidence and abrief summary of wetland attributes that have developed in the Bank during the first year after restoration. ' A photographic database has been developed in the Bank and in reference wetlands. Twenty three stations have been photographed weekly to monthly throughout the 1998 growing season. ' Additional photographs have been collected that exhibit conditions at the Bank prior to restoration and during construction activities. The entire photographic database is available for review upon request. Referenced photographs are attached to the end of this section. 5.1 PRE-RESTORATION CONDITIONS (January 1997 to November 1997) ' The 623-acre Bank is located on lower portions of a broad coastal plain interstream divide which includes the historic origin of Harrison Creek. Adjacent flats and ridges comprise a watershed encompassing approximately 9.8 square miles (mil) of land with groundwater and surface water ' discharging from these flats and terraces towards the Bank. A majority of the Bank was cleared, ditched, and drained in the last 30 years with wetlands and streams effectively eliminated. The ' drainage network included approximately 100,000 linear feet (ft) of ditches and canals (Photograph 1-2). The drainage area that historically flowed through the Bank was diverted into constructed canals which bypassed Harrison Creek and the riverine wetland corridor. Drainage networks ' effectively eliminated stream and wetland functional attributes in the Bank (Photograph 3-4). 5.2 WETLAND CONSTRUCTION ACTIVITIES (November 1997 to January 1998) ' Restoration activities included placement of impervious plugs and backfilling of all ditches and canals in the Bank (Photograph 5-6). Former canal flows from the upper watershed were diverted ' into the headwater slope physiographic area of the Bank through construction of intermittent drainageways (Photograph 7-8). The headwater slope and former floodplain were reconnected through berm removal and cleaning of the relict stream channel. Soil surfaces on former crop land ' were scarified to increase microtopography and surface water storage (Photograph 9a-10a). Subsequently, the site was planted with 192,000 diagnostic tree seedlings as detailed in the ' mitigation plan (Photograph 9b-10b). 5.3 POST-RESTORATION CONDITIONS (January 1998 to October 1998) In January 1998, surface water from the upper watershed inundated the Bank. Depth of water generally ranged from saturation to elevations approximately 4 feet above the soil surface. Due to ' the extent of inundation and flow velocities, two canal plugs in northern reaches of the Bank were blown out during this period and subsequently reconstructed to prevent overtopping by surface water. ' Inundation and influent surface waters generally continued from January through early June (Photograph 11-12). Blooms of algae and large populations of amphibians and fish developed within the Bank during this period. Characteristic species associated with aquatic wetland habitats ' 22 n 1 0 Lam' included sunfish (Lepomis sp.), lesser siren (Siren intermedia), southern cricket frog (Acris gryllus), grey treefrog (Hyla chrysoscelis), green treefrog (Hyla cinerea), spring peeper (Pseudacris crucifer), pine woods treefrog (Hyla femoralis), snapping turtle (Chelydra serpentina), spotted turtle (Clemmys guttata), and water snake (Nerodia sp.). Fish populations became stranded in isolated pools during the summer and attracted a large population of wetland dependent avifauna to the Bank. On 9 July 1998, over 1000 coastal birds were observed feeding in desiccating pools, including great egret (Casmerodius albus), cattle egret (Bubulcus ibis), great blue heron (Ardea herodias), green heron (Butorides striatus), wood duck (Aix sponsa), mallard (Anas platyrhynchos), red-tailed hawk (Buteo jamaicensis), belted kingfisher (Megaceryle alcyon), and merlin (Falco columbarius). Black bear (Ursus americanus) also frequent protected portions of the Bank. Photograph 13 provides a comparison of surface water conditions between the wetland restoration area and adjacent prior converted farmland that continues to support drainage networks. The photograph was taken approximately 2 months after the drainage network was removed and watershed drainage was diverted into the Bank. Due to drainage redirection into the historic origin of Harrison Creek, significant stream flows of greater than 20 cubic feet per second (CFS) were initiated in the headwater slope and riverine floodplain physiographic areas of the Bank during the spring of 1998 (Photograph 14-15). The historic stream exhibited evidence of channel development during the spring and early summer months (Photograph 16-17). During an MBRT site visit in the early spring of 1997 (pre-restoration condition), the former stream corridor was dry and lacked distinct evidence of an existing stream channel. Photographs 18-23 depict a chronological sequence of wetland surface hydrology at Station #11 as depicted in Figure 2. The Station is located at a constructed intermittent drainageway that serves as the primary infall from the watershed into the Bank. The view generally parallels the primary diversion canal that was plugged and backfilled during wetland construction. The constructed intermittent drainageway extends perpendicular across the bottom of the photograph. Photograph 23 was taken at a 90 degree angle to photographs 18-22 to provide a view of the constructed drainageway in the downstream direction. Influent surface waters inundated the area from January through early June of 1998 (Photograph 18-19). In late June (Photograph 20-21), rapid groundwater draw-down and cessation of surface water inputs occurred during a drought period. However, surface water inputs occurred after periodic storms in August/early September with relatively constant flows re-establishing in September (Photograph 22-23). Photographs 24-29 depict a chronological sequence within the reference (relatively undisturbed) ' groundwater flat wetland. Similar to the Bank, reference wetlands were inundated until early June (Photograph 24-25). In June, the water table dropped over two feet below the soil surface in ' 23 C? 0 1 1 reference (Photograph 26-27). Surface water hydrology has not re-established in reference during the month of September (Photograph 28-29). As depicted in the chronological sequence, herbaceous wetland vegetation began to colonize the site after inundation ceased in late June. Characteristic hydrophytic species include panicum grasses, sedges, cat tail, seedbox, knotweed, Ludwegia, and wool-grass. In wetland restoration areas, planted trees exhibited, on average, an 83% survival rate. Survival rates were highest among seedlings that supported well developed above-ground stems extending more than 3 feet above the soil surface (primarily bald cypress, swamp tupelo, water tupelo, and oak species). Atlantic white cedar seedlings supported little or no above ground stems; therefore, the extent of inundation appears to have induced mortality of greater than 70% for this planted species. In summary, the bank developed wetland habitat that exhibited hydrological characteristics similar to the reference wetlands. Functional attributes exhibited include long term surface water storage, energy dissipation, retention of nutrients and particulates, and establishment of characteristic wetland species populations. Although isolated pockets of emergent wetlands may develop, a majority of the Bank appears to support hydroperiods and successional patterns conducive to establishment of forested habitat. The Bank has fulfilled success criteria for development and maintenance of wetland hydrology and wetland vegetation for 1998 (Year 1 AWMR). Table 5 provides a summary of credit release through November 1998, contingent upon approval of the MBI. Insufficient data has been collected within the Bank and within reference to evaluate success criteria for stream restoration. Therefore, data will be collected and analyzed to evaluate stream hydrology, geometry, and biology for the Year 2 AWMR (November 1999). 24 11 1 1 1 1 1 t Photograph 13: Post-restoration condition: comparison of surface water storage in the restored wetlands and adjacent farmlands that continue to support drainage networks. k'?ta+ PANORAMIC VIEW SHOWING RESTORED PHASE I (FAR LEFT) ADJACENT TO PHASE 11 LAND STILL IN AGRICULTURAL PRODUCTION (FAR RIGHT (JANUARY, 1998) Photograph 1 - 2: Pre-restoration condition: constructed ditches and effective drainage.

STATION 21 9/30/98 1 1 1 1 1 1 1 11 APPENDIX A REVISED, FINAL MONITORING PLAN 26 1 1 1 1 1.0 REVISED. FINAL MONITORING PLAN The Monitoring Plan will consist of a comparison between hydrology model predictions, reference streams and wetlands, and restoration areas on the Site. Stream restoration monitoring will be performed through analysis of in-stream flows, stream geometry, and biological stream attributes. Wetland monitoring will entail analysis of two primary parameters: vegetation and hydrology. Monitoring of restoration and enhancement efforts will be performed until success criteria are fulfilled. 1.1 HYDROLOGY MONITORING After hydrological modifications are being performed on the site, surficial monitoring wells will be designed and placed in. accordance with specifications in U.S. Corps of Engineers', Installing Monitorina Wells/Piezometers in Wetlands (WRP Technical Note HY-IA-3.1, August 1993). Monitoring wells will be set to a depth of approximately 24 inches below the soil surface. Twenty three surficial monitoring wells (manual recording) will be installed at the Site to provide representative coverage and flow gradients extending through each of the three physiographic landscape areas (Figure 2). Four monitoring wells will also be placed within the reference wetland site in similar landscape positions, where available. Three continuous recording (RDS24) wells will also be installed on-site to provide continuous data that can be extrapolated to manual recording devices. ' Hydrological sampling will be performed on-site and within reference during the growing season (17 March to 12 November) at intervals necessary to satisfy the hydrology success criteria within the ' designated physiographic area (EPA 1990). In general, the wells will be sampled weekly through the Spring and early Summer and intermittently through the remainder of the growing season, if ' needed to verify success. 1.2 HYDROLOGY SUCCESS CRITERIA Target hydrological characteristics have been evaluated using a potential combination of three ' different methods: 1) regulatory wetland hydrology criteria; 2) reference groundwater modeling; and 3) reference wetland sites. ' Regulatory Wetland Hydrology Criteria The regulatory wetland hydrology criterion requires saturation (free water) within one foot of the soil surface for 12.5 percent of the growing season under normal climatic conditions. In some instances, the regulatory wetland hydroperiod may extend for between 5 and 12.5% of the growing season. ' Reference Groundwater Model The reference groundwater model forecasts that the wetland hydroperiod in interior areas of the Site will average 22% of the growing season in early successional phases. As steady state forest ' conditions develop, the average wetland hydroperiod is forecast to encompass 40% of the growing season. Over the 31 year modeling period, the annual hydroperiod fluctuated from less than 12.5% to over 44% dependent upon rainfall patterns and successional phase. In addition, the on-site ' Page 1 of 5 u ' landscape includes diverse wetland geomorphology, especially near uplands and the stream channel, which are not characterized by the model. ' Due to wide fluctuations in modeled annual hydroperiod (<12-44+%), the groundwater model cannot provide a specific hydrology success criteria above the regulatory criterion (12.5%) on an annual basis. A specific success criteria such as a 22% target hydroperiod will fail in 50% of the years ' sampled. A success criteria of 12.5% (the regulatory criteria) will also fail in 10% of the years sampled in reference wetlands. Reference Wetland Sites Four monitoring wells will be placed in the groundwater flats reference wetland located in the northwestern periphery of Barra Farms. Wells will be also be placed in a riverine reference wetland in the Bushy Lake/Horse shoe Lake natural area dependent upon contact with the North Carolina Park and Recreation Service. These wells will provide annual hydroperiods on the organic soil flat, and riverine floodplain physiographic areas of the Site. The headwater slope physiographic area may be interpolated between the two systems. Transition zones from uplands towards the wetland interior will not be represented. Therefore, these wells will provide comparative information on interior wetlands only. The hydrology success criteria for this Site will require saturation (free water) within one foot of the soil surface for at least 50% of the hydroperiod exhibited by the reference wetland. Based on groundwater models, average wetland hydroperiods in groundwater flats will exhibit a ' steady, non-linear increase from 22% to 40% of the growing season during forest (post-farmland) development. This trend includes a hypothetical reduction in hydraulic conductivities and a 50% increase in surface water storage through the first 15 years of wetland development. Therefore, a ' goal of 50 +/-% hydroperiods relative to reference wetlands is warranted for the five year monitoring period. This 50% goal may not apply in non-organic soils as evapotranspiration may play a greater role in early successional hydroperiods than surface water storage. ' 1.3 VEGETATION Restoration monitoring procedures for vegetation are designed in accordance with EPA guidelines ' presented in Mitigation Site Type (MiST) documentation (EPA 1990) and COE Compensatory Hardwood Mitigation Guidelines (DOA 1993). The following presents a general discussion of the monitoring program. After planting has been completed in winter or early spring, an initial evaluation will be performed to verify planting methods and to determine initial species composition and density. Supplemental ' planting and additional site modifications will be implemented, if necessary. During the first year, vegetation will receive cursory, visual evaluation on a periodic basis to ' ascertain the degree of overtopping of planted elements by weeds. Subsequently, quantitative sampling of vegetation will be performed between September 1 and October 31 after each growing ' season until the vegetation success criteria is achieved.

within each restored ecosystem type. approximately twenty three plots will be correlated with hydrological monitoring locations to provide point-related data on hydrological and vegetation parameters. 1.4 VEGETATION SUCCESS CRITERIA Success criteria have been established to verify that the wetland vegetation component supports a species composition sufficient for a jurisdictional determination. Additional success criteria are dependent upon the density and growth of characteristic forest species. Specifically, a minimum mean density of 320 characteristic trees/ac must be present for the five year monitoring period. Characteristic tree species are those within the reference ecosystems, elements enumerated in the planting plan, along with natural recruitment of sweet gum, red maple, loblolly bay, loblolly pine, black willow, and pond pine. Softwood species) cannot comprise more than 10 percent of the 320 stem/acre requirement. In addition, at least five character tree species must be present, and no species can comprise more than 20 percent of the 320 stem/acre total. Supplemental plantings will be performed as needed to achieve the vegetation success criteria. N No quantitative sampling requirements are proposed for herb and shrub assemblages as part of the vegetation success criteria. Development of a forest canopy over several decades and restoration of wetland hydrology will dictate the success in migration and establishment of desired wetland understory and groundcover populations. Visual estimates of the percent cover/composition of shrub and herbaceous species and photographic evidence will be reported for information purposes. 1.5 STREAM ' Stream monitoring and success criteria will be established through measurement of in-stream flows, measurement of stream geometry, and measurement of biological stream attributes. ' In-stream flows will be measured through placement of two continuos monitoring stream flow gauges. The gauges will be capable of recording velocity (ft/second) and discharge (cubic feet per second, CFS). Discharge is typically calculated by measuring height (or depth) of the water column ' and inputting the resulting cross-section. One gauge will be placed at a culvert located approximately 300 feet below stream outfall from the Bank (Drainage Area: 2.5 mi2). The second gauge will be placed within the culvert and State road crossing at the riverine wetland reference site ' in Bladen Lakes State Forest (Drainage Area: 6.7 mi2). The data will be reported as mean daily flows for velocity (ft/second) and discharge (CFS) in tabular and graphic format. ' Stream geometry will be measured along a fixed stream reach located in central portions of the mitigation stream reach. The stream reach will extend for a minimum of 200 feet along the restored channel. Annual fall monitoring will include development of a channel plan view, three channel ' cross-sections, pebble counts, and a water surface profile of the channel. The data will be presented in graphic and tabular format as summarized in the attached table. Data to be presented will include: 1) cross-sectional area; 2) bankfull width; 3) average depth; 4) average width; 5) width/depth ratio; ' 6) meander wavelength; 7) beltwidth; 8) water surface slope; 9) sinuosity; and 10) stream substrate composition. The stream will subsequently be classified according to stream geometry and substrate ' (Rosgen 1996). Significant changes in channel morphology will be tracked and reported by Page 3 of 5 1 1 1 1 1 u I? 'I I comparing data between the reference stream and mitigation stream and by comparing data in each successive monitoring year. Biological stream attributes will be measured annually at the mitigation site and in the reference wetland site between April 15 and May 15 of each year. Aquatic surveys will record presence/absence of macro-invertebrate, reptile, amphibian, and fish species populations. Presence/absence of species populations identified will be reported along with observations of changes to in-stream aquatic habitat or species presence/absence over time. 1.6 STREAM SUCCESS CRITERIA Success criteria for stream restoration will include: 1) stream classification; 2) target mean daily stream flows; and 3) increased stream faunal recruitment and diversity. Stream geometry measurements will be incorporated into the Rosgen stream classification system. The channel and flood prone area must support characteristics supporting an E, C, or DA stream type to fulfill the success criteria. In-stream flow measurements must indicate that the mitigation stream reach supports average annual, mean daily flows per unit of drainage area equal to, or exceeding the average annual, mean daily flows per unit of drainage area within the reference stream reach. Due to potential rainfall differences within each watershed, a five percent deviation in average annual, mean daily flows ' between the reference and mitigation stream reaches will be allowed by the MBRT. The reference stream reach supports an approximate 6.7 mil drainage area while the mitigation stream reach supports an approximate 2.5 miz drainage area (37% of reference). Therefore, average annual, mean ' daily flows in the mitigation reach must equal to or exceed 32% of the average annual, mean daily flows in reference. If the mitigation reach nd/or ference reach support no measurable flow during ' a drought period, fulfillment of success criteria will be based upon mean daily flows prior to, and following the no flow condition. ' Biological monitoring will indicate similar species diversity as compared to reference conditions or an increase in species diversity towards reference conditions over time. Specifically, the type and number of species populations identified in the mitigation reach must be equal to, or increasing ' towards, the type and number of species identified in the reference reach in each successive monitoring year. However, because the Bank supports a developing stream reach, allowances may be given and justified when evaluating future data. t 1.7 REPORT SUBMITTAL Documentation will be submitted to the MBRT certifying completion of implementation activities. ' Any changes to this mitigation plan will be described in this documentation. The document will be provided within 60 days of completion of all work at the Site. ' Subsequently, reports will be submitted yearly to the MBRT following each assessment. Reports will document the sample transect locations, along with photographs which illustrate site conditions. 1 Page 4 of 5 1 1 1 1 1 fl 0 C Surficial well data will be presented in tabular/graphic format. The duration of wetland hydrology during the growing season will be calculated at each well, within each on-site physiographic area, and within the reference wetland site. The survival and density of planted tree stock will be reported. In addition, characteristic tree species mean density and average height as formatted in the Vegetation Success Criteria will be calculated. Estimates and photographic evidence of the relative percent cover of understory and groundcover species will be generated. 1.8 CONTINGENCY In the event that vegetation or hydrology success criteria are not fulfilled, a mechanism for contingency will be implemented. For vegetation contingency, replanting and extended monitoring periods will be implemented if community restoration does not fulfill minimum species density and distribution requirements. Hydrological contingency will require consultation with hydrologists and regulatory agencies if wetland hydrology restoration is not achieved during the monitoring period. Recommendations for contingency to establish wetland hydrology will be implemented and monitored until the Hydrology Success Criteria are achieved. Performance bonds have been established to guarantee fiscal resources for remediation. 1 H Page 5 of 5 1 if te- DEPARTMENT OF THE ARMY WILMINGTON DISTRICT, CORPS OF ENGINEERS P.O. BOX 1890 WILMINGTON, NORTH CAROLINA 28402-1890 IN REPLY REFER TO June 15, 2000 Regulatory Division Action ID No. 199704890, Barra Farm Mitigation Bank Mr. Alan Fickett ECOBANK 1555 Howell Branch Road Winter Park, Florida 32789 Dear Mr. Fickett: 20 `?r7 Reference the Year Two Wetland Monitoring Report for the Barra Farms Wetland Mitigation Bank describing conditions at the Bank site as of November of 1999. We have also been provided a copy of the Progress Report that describes the additional tree planting that was done in February of 2000 and the supplemental vegetative monitoring. It is our understanding that the supplemental planting was accomplished with two-year old bare root seedlings. As you are aware, we expressed considerable concern over the observed and measured tree mortality that occurred during the year one and year two monitoring intervals. Based on these concerns the site was replanted with approximately 43,300 two-year bare root seedlings in February Of 2000. In addition, you have installed several corrugated metal pipes across the northern perimeter road to remove surface water in an effort to reduce tree mortality. As the remedial actions have been completed and the Progress Report and May 11, 2000 site visit confirmed that the remedial planting was successful, we agree that you have met the required success criteria and, accordingly, agree to release year two credits (36) from the Bank. As discussed on May 11, release of stream credit is not allowed until the year one monitoring report successfully demonstrates that you have met the stated success criteria. It is also our understanding that you would like to commence monitoring of the Bank for year three during the early summer of 2000 such that year three credits would be released (provided success criteria could be met) in the fall of 2000. Based on our review of the monitoring reports, it would be inappropriate to accelerate the monitoring schedule and release of credits. This decision is based on our review of the last two monitoring reports that indicate that significant tree mortality has occurred.

The comments which follow also include observations from the May-W site Hydrology Based on evaluation of the presented data and se eral field inspections, DWQ feels that Barra Farms has met hydrologic success criteria The DWQ appreciates the presentation of the RDS well data in graphical format as requested in our June 22, 1999 letter for Monitoring Report Year 1. However, as we pointed out on the May 11, 2000 site visit we need to know the location of these wells. Evidently, the labeling of the RDS wells in the graphical format 4i the well serial numbers, and there was no way to identify the wells with the map. In addition, in our June 22, 1999 letter we requested that a correlation be performed between the manual wells and the RDS wells. Upon inspection of the drainage pipes which were installed, DWQ does not believe that these pipes are affecting drainage of the groundwater on site. Vegetation The vegetation suc ess criteria is the central issue in the decision to release the next phase of credits a , The success criteria is as follows: "...a minimum mean density o 320 characteristic trees/acre. At least five character tree species must be present, and no species can comprise more than 20 percent of the 320 stemlacre total. Softwood species (ex: loblolly nine, pond pine, and black willow) cannot comprise more than 10 percent of the 320 stemlacre requirement. " J EcoBank representatives replanted areas of deficiency (noted in our June 22, 1999 letter concerning Monitoring Year 1 vegetation deficiencies) on February 8-11, 2000 with l? 43,000 here seedlings. In addition, DWQ approves of the new monitoring s h6r 'e with increased number of plots and size resulting in a larger portion of the site being sampled. Land Manag ' ent, Inc. monito ed the new plantings in April to test for survivability at leaf out. ?to the ntwtn s in them supplemental report, they show Barra Farms currently meeting the vegetation success criteria. However, DWQ believes that in order to release credits for Monitoring Year 2, monitoring of the newly planted seedlings must be toward the end of the respective growing season. The?DW?Q approves of the ahe ns taken to reduce t 50-60 acre pondi. In addition, QV appreciates the o f the vegetation data in a plot form-aa in the Supplemental Actions Report. Stream The DWQ realizes that the Stream Restoration Monitoring Year 1 report is not finalized as yet, however, we would like to relate severs oncems noted on the May 11, 2000 site visit. First of all, in our June 22, 1999 letterOve recommended that the flowmeter at the outlet of the site be moved to the rear of the pipe. This would reduce the amount of misreadings caused by turbulence at the entrance of the culvert. i Secondly, and the main concern for DWQ, is the reference stream and the placement of the flowmeter in one of three open culverts. As you may recall, the -wkok credit release schedule for the stream restoration component of the bank is based on success criteria related to the flow of the site as compared to the reference site. Tl?va?rrrent `?c?TcrPrr, ?? ?P h t, does not believe an accurate comparison can be made between the restoration and reference stream. herefbre,?kntil both flowmeters are-eorrect1- installed 1- i and functioning-and-the refere cn a stream conditions are appropriate, would the stream momtormg initiate. Recommendations At the May 11, 2000 site visit, EcoBank Sponsors requested the immediate release of Monitoring Year 2 (wetland) credits and after a fall monitoring, the release of Monitoring "P? Year (3) (wetland) credits. The DWQ feels that it is inappropriate to release Year 2 credits based upon an April monitoring report of recently planted seedlings. However, given the recent improvements to the site, DWQ would approve of an immediate partial release (5%) of the credits. The DWQ recommends that to acquire the remainder of Year 2 credits (10%), another monitoring of the site be performed no earlier than the last week of August. Once this report is submitted and the success criteria have been met, then the remainder of Year 2 credits may be released. However, Year 3 credits would not be available until after the growing season in 2001. r?=?.L`?,4f;%? 1? fnrcv?rrl *?+ 1? g of"Ou _ Respectfully, Mac Haupt Implementation Coordinator DWQ-Wetland Restoration Program CC: John Dorney, DWQ-Wetlands/401 Unit Ken Averitte, DWQ-FRO i ? 47 _-' - r _ - -- fJ FJil'?? ?? c r rl `7?t'l' l?.r n-,..2,??ci`1--iZ ??? ?" ?? f?.y _?t jr'• _7?<: A o 1 ?? ?? r C?

Box 1890 Wilmington, NC 28402-1890 RE: Barra Farms Wetland Monitoring Report (Year 1) Dear Mr. McLendon, The Division of Water Quality (DWQ) has reviewed the Wetland Monitoring Report: Year 1 from Barra Farms Cape Fear Regional Bank. The comments which follow also include observations from a May 5t' site visit: Hvdrolga Based on evaluation of the presented data and several field inspections, DWQ feels that Barra Farms has met hydrologic success criteria. However, DWQ would like to make several recommendations with regard to the presentation of the hydrologic data. First of all, it was apparent from the Year 1 report that no RDS well data was reported. Evidently the wells were malfunctioning, but have since been replaced (prior to 5/5/99) and are now being monitored. DWQ would like to see the hydrographs from the RDS wells presented in the Year 2 report. In addition, for the Year 2 report, DWQ would like to see correlations with hand read wells and the reference site wells. Stream On the May 5t' site visit, it was noted that the stream flowmeter was in place at the exiting culverts on site. In addition, it was apparent that of the three culverts present, two had been blocked off. However, upon further consultation with our resident hydrologist (Jeff Jurek), we recommend that the flowmeter be moved to the other end of the culvert (exiting end). The turbulence caused by the water attempting to flow into the single culvert would cause false readings at the head of the culvert. DWQ would also like to see the reference stream and flowmeter, perhaps a meeting could be set up with yourself or a bank representative in the near future. Vegetation The vegetation success criteria is the central issue in the decision to release the next phase of credits (10%). The success criteria is as follows: "...a minimum mean density of 320 characteristic trees/acre. At least five character tree species must be present, and no species can comprise more than 20 percent of the 320 stem/acre total. Softwood species (ex: loblolly_pine, pond pine, and black willow) cannot comprise more than 10 percent of the 320 stem/acre requirement. " Tables 2 and 3 were offered in the Year 1 report as evidence of the bank meeting the above vegetation success criteria. However, DWQ does not feel that the Tables reflect the proper interpretation of the data. At the site visit on May the 5"', the MBRT members were handed the plot data gathered by EcoScience, Inc. Upon further review of the plot data DWQ found that when the plots were examined individually, 46% passed the minimum number of stems with recruitment and 43% passed the minimum number of planted species (Table 1). The plots would need to have at least a 60% passage rate before the minimum number of stems could be considered "successful". In addition to looking at the plots individually, we examined the plots by physiographic region. We examined the sample plots present in the Headwater Slope wetlands, Riverine wetlands, and the Groundwater flats. The results of finding at least 16 stems present for each .05 acre plot were as follows: 1)headwater slope - 83% passed, 2) riverine wetlands - 0% passed, and 3) groundwater flats - 37% passed (Table 2). The vegetation success criteria also calls for diversity within the plan, however, since the success criteria was not met for the minimum number, DWQ feels that it is nebulous to comment on the diversity of the species at this time. Moreover, DWQ feels that the bank will not be able to meet the diversity criteria on a per plot basis. Therefore, a restructuring of the vegetation success criteria regarding species diversity would have to be addressed by the bank and the MBRT. Perhaps species diversity could be addressed on a physiographic region basis. In addition to the minimum number plot data, the May 5t' site visit revealed areas which were more than one or two acres in size where no planted trees appeared to survive. These areas were not picked up to a great extent by the sample plots because the sampling scheme was too small (26 plots @ .05 acres = 1.3 acres or .21% of site sampled). The site visit on May 5 h also revealed a rather large section (approximately 50-60 acres) of the bank (roughly 10% of the bank area) exhibited a freshwater marsh habitat. Of course, DWQ recognizes the high value of freshwater marsh wetlands, however, the bank's restoration plan did not call for any marsh restoration. DWQ recommends, routing the water from this marsh habitat so that the marsh area is no more than 20 acres.

DWQ recommends a release of 5% of the credits based on the fact that the vegetation success criteria were not met. DWQ recommends using the existing plots and increasing their size to one acre. Basically, this changes the radius of the existing plot from 26 feet to 117 feet. The increase in size should not represent a considerable increase in sampling costs and the total sampled area will increase from .21% of the area to 4% (or 1.3 acres to 26 acres). In addition, prior to the next reporting period, DWQ recommends that the bank: 1. Report RDS hydrological data in graphical format; 2. Correlate RDS data to hand sampled wells; 3. Increase size of sample plots; and 4. Move flowmeter to exit portion of culvert. Areas where DWQ recommends replanting include: the area just east of P8, the area around P6, and areas around P 13 A-B, P 14, P 18, P21, P23, and P24 A-B. DWQ would the release of the remaining 5% credit when the following remedial actions have been met: 1. Replant specified areas of bank; 2. Reroute some water from marsh area to stream area; and 3. Report data in next report in plot specific format. Thank you for the opportunity to comment and we look forward to hearing from you.

Upon further review of the plot data DWQ found that when the plots were examined individually, 46% passed the minimum number of stems with recruitment and 43% passed the minimum number of planted species (Table 1). The plots would need to have at least a 60% passage rate before the minimum number of stems could be considered "successful". In addition to looking at the plots individually, we examined the plots by physiographic region. We examined the sample plots present in the Headwater Slope wetlands, Riverine wetlands, and the Groundwater flats. The results of finding at least 16 stems present for each.05 acre plot were as follows: 1)headwater slope - 83% passed, 2) riverine wetlands - 0% passed, and 3) groundwater flats - 37% passed (Table 2). The vegetation success criteria also calls for diversity within the plan, however, since the success criteria was not met for the minimum number, DWQ feels that it is nebulous to comment on the diversity of the species at this time. Moreover, DWQ feels that the bank will not be able to meet the diversity criteria on a per plot basis. Therefore, a restructuring of the vegetation success criteria regarding species diversity would have to be addressed by the bank and the MBRT. Perhaps species diversity could be addressed on a physiographic region basis. In addition to the minimum number plot data, the May 5"' site visit revealed areas which were more than one or two acres in size where no planted trees appeared to survive. These areas were not picked up to a great extent by the sample plots because the sampling scheme was too small (26 plots @ .05 acres = 1.3 acres or .21% of site sampled). The site visit on May 5 h also revealed a rather large section (approximately 50-60 acres) of the bank (roughly 10% of the bank area) exhibited a freshwater marsh habitat. Of course, DWQ recognizes the high value of freshwater marsh wetlands, however, the bank's restoration plan did not call for any marsh restoration. DWQ recommends, routing the water from this marsh habitat so that the marsh area is no more than 20 acres.

DWQ recommends a release of 5% of the credits based on the fact that the vegetation success criteria were not met. DWQ recommends using the existing plots and increasing their size to one acre. Basically, this changes the radius of the existing plot from 26 feet to 117 feet. The increase in size should not represent a considerable increase in sampling costs and the total sampled area will increase from .21% of the area to 41/o (or 1.3 acres to 26 acres). In addition, prior to the next reporting period, DWQ recommends that the bank: 1. Report RDS hydrological data in graphical format, 2. Correlate RDS data to hand sample&wells; 3. Increase size of sample plots; and 4. Move flowmeter to exit portion of culvert. Areas where DWQ recommends replanting include: the area just east of P8, the area around P6, and areas around P13 A-B, P14, P18, P21, P23, and P24 A-B. DWQ would the release of the remaining 5% credit when the following remedial actions have been met: 1. Replant specified areas of bank; 2. Reroute some water from marsh area to stream area; and 3.

Box 1890 Wilmington, NC 28402-1890 RE: Barra Farms Wetland Monitoring Report (Year 1) Dear Mr. McLendon, The Division of Water Quality (DWQ) has reviewed the Wetland Monitoring Report: Year 1 from Barra Farms Cape Fear Regional Bank. The comments which follow also include observations from a May 56' site visit: Hydrology Based on evaluation of the presented data and several field inspections, DWQ feels that Barra Farms has met hydrologic success criteria. However, DWQ would like to make several recommendations with regard to the presentation of the hydrologic data. First of all, it was apparent from the Year 1 report that no RDS well data was reported. Evidently the wells were malfunctioning, but have since been replaced (prior to 5/5/99) and are now being monitored. DWQ would like to see the hydrographs from the RDS wells presented in the Year 2 report. In addition, for the Year 2 report, DWQ would like to see correlations with hand read wells and the reference site wells. Stream On the May 50' site visit, it was noted that the stream flowmeter was in place at the exiting culverts on site. In addition, it was apparent that of the three culverts present, two had been blocked off. However, upon further consultation with our resident hydrologist (Jeff Jurek), we recommend that the flowmeter be moved to the other end of the culvert (exiting end). The turbulence caused by the water attempting to flow into the single culvert would cause false readings at the head of the culvert. DWQ would also like to see the reference stream and flowmeter, perhaps a meeting could be set up with yourself or a bank representative in the near future. Vegetation The vegetation success criteria is the central issue in the decision to release the next phase of credits (10%). The success criteria is as follows: "...q minimum mean density of 320 characteristic trees/acre. At least five character tree species must be present, and no Wecies can comprise more than 20 percent of the 320 stem/acre total. Sowspecies (ex: loblolly pine, pond pine, and black willow) cannot comprise more than 10 percent o? the 320 stem/acre requirement. " Tables 2 and 3 were offered in the Year 1 report as evidence of the bank meeting the above vegetation success criteria. However, DWQ does not feel that the Tables reflect the proper interpretation of the data. At the site visit on May the 5th, the MBRT members were handed the plot data gathered by EcoScience, Inc. Upon further review of the plot data DWQ found that when the plots were examined individually, 46% passed the minimum number of stems with recruitment and 43% passed the minimum number of planted species (Table 1).

BOX 1890 WILMINGTON, NORTH CAROLINA 28402-1890 IN REPLY REFER TO January 27, 2000 Regulatory Division Action ID No. 199704890, Barra Faun Mitigation Bank Mr. Alan Fickett ECOBANK 1555 Howell Branch Road Winter Park, Florida 32789 Dear Mr. Fickett: Reference the Remedial Actions and Supplemental Planting Plan for the Barra Farms Wetland Mitigation Bank, dated October 8, 1999, and in which you describe the remedial actions to be undertaken at this Bank. It is our understanding that the remedial planting will occur on February 7 and 8, 2000 and that once leaf-out has occurred, ECOBANK will prepare an interim monitoring report that describes the survival of the newly planted trees. Notwithstanding our comment below, we agree that you have satisfied our requirements as outlined in our meeting held on September 28, 1999, and our letter dated July 8, 1999. Accordingly, year one credits (24) from the Bank are available for use. As always, future decisions concerning the acceptability of the use of this bank to mitigate for the impacts of any particular permit will be made during the permit review process of that permit. We note that the plan describes the installation of several flash-board risers on the north side of the restoration area. Historically, we have prohibited the use of artificial measures to manipulate water levels on mitigation sites. This is due to necessary future maintenance and because these strictures can be tampered with easily. For these reasons, all flash-board risers will need to be removed once the trees have grown such that they will not be inundated with. ponded water. We again suggest you evaluate the affect the berm on the south side of the site is having on the retention of surface water in the former agricultural fields.

Monitoring of wetland restoration and enhancement efforts will be performed until success criteria are fulfilled. Monitoring is proposed for two wetland components, vegetation and hydrology. Wetland soils currently exist within restoration areas and monitoring is not considered necessary to verify hydric soil requirements for a jurisdictional determination. 7.1 HYDROLOGY MONITORING After hydrological modifications are being performed on the site, surficial monitoring wells will be designed and placed in accordance with specifications in U.S. Corps of Engineers', Installing Monitorina Wells/Piezometers in Wetlands (WRP Technical Note HY-IA-3.1, August 1993). Monitoring wells will be set to a depth of approximately 24 inches below the soil surface. Twenty three surficial monitoring wells (manual recording) will be installed at the Site to provide representative coverage and flow gradients extending through each of the three physiographic landscape areas (Figure 14). Four monitoring wells will also be placed within the reference wetland site in similar landscape positions, where available. Three continuous recording (RDS24) wells will also be installed on-site to provide continuous data that can be extrapolated to manual recording devices. Hydrological sampling will be performed on-site and within reference during the growing season (17 March to 12 November) at intervals necessary to satisfy the hydrology success criteria within the designated physiographic area (EPA 1990). In general, the wells will be sampled weekly through the Spring and early Summer and intermittently through the remainder of the growing season, if needed to verify success. 7.2 HYDROLOGY SUCCESS CRITERIA Target hydrological characteristics have been evaluated using a potential combination of three different methods: 1) regulatory wetland hydrology criteria; 2) reference groundwater modeling; and 3) reference wetland sites. Regulatory Wetland Hydrology Criteria The regulatory wetland hydrology criterion requires saturation (free water) within one foot of the soil surface for 12.5 percent of the growing season under normal climatic conditions. In some instances, the regulatory wetland hydroperiod may extend for between 5 and 12.5% of the growing season. Reference Groundwater Model The reference groundwater model forecasts that the wetland hydroperiod in interior areas of the Site will average 22% of the growing season in early successional phases. As steady state forest conditions develop, the average wetland hydroperiod is forecast to encompass 36 ? Y 40% of the growing season. Over the 31 year modeling period, the annual hydroperiod fluctuated from less than 12.5% to over 44% dependent upon rainfall patterns and successional phase. In addition, the on-site landscape includes diverse wetland geomorphology, especially near uplands and the stream channel, which are not characterized by the model. Due to wide fluctuations in modeled annual hydroperiod (< 12-44+ %), the groundwater model cannot provide a specific hydrology success criteria above the regulatory criterion (12.5 %) on an annual basis. A specific success criteria such as a 22% target hydroperiod will fail in 50% of the years sampled. A success criteria of 12.5% (the regulatory criteria) will also fail in 10% of the years sampled in reference wetlands. Reference Wetland Sites Four monitoring wells will be placed in the groundwater flats reference wetland located in the northwestern periphery of Barra Farms. Wells will be also be placed in a riverine reference wetland in the Bushy Lake/Horse shoe Lake natural area dependent upon contact with the North Carolina Park and Recreation Service. These wells will provide annual hydroperiods on the organic soil flat, and riverine floodplain physiographic areas of the Site. The headwater slope physiographic area may be interpolated between the two systems. Transition zones from uplands towards the wetland interior will not be represented. Therefore, these wells will provide comparative information on interior wetlands only. The hydrology success criteria for this Site will require saturation (free water) within one foot of the soil surface for at least 50% of the hydroperiod exhibited by the reference wetland. Based on groundwater models, average wetland hydroperiods in groundwater flats will exhibit a steady, non-linear increase from 22% to 40% of the growing season during forest (post- farmland) development. This trend includes a hypothetical reduction in hydraulic conductivities and a 50% increase in surface water storage through the first 15 years of wetland development. Therefore, a goal of 50 +/-% hydroperiods relative to reference wetlands is warranted for the five year monitoring period. This 50% goal may not apply in non-organic soils as evapotranspiration may play a greater role in early successional hydroperiods than surface water storage. 7.3 VEGETATION Restoration monitoring procedures for vegetation are designed in accordance with EPA guidelines presented in Mitigation Site Type (MIST) documentation (EPA 1990) and COE Compensatory Hardwood Mitigation Guidelines (DOA 1993). The following presents a general discussion of the monitoring program. After planting has been completed in winter or early spring, an initial evaluation will be performed to verify planting methods and to determine initial species composition and density. Supplemental planting and additional site modifications will be implemented, if necessary. 37 During the first year, vegetation will receive cursory, visual evaluation on a periodic basis to ascertain the degree of overtopping of planted elements by weeds. Subsequently, quantitative sampling of vegetation will be performed between September 1 and October 31 after each growing season until the vegetation success criteria is achieved. After planting plan implementation, 0.1 acre plots will be within each restored ecosystem type. Twenty three plots will be correlated with hydrological monitoring locations to provide point- related data on hydrological and vegetation parameters. 7.4 VEGETATION SUCCESS CRITERIA Success criteria have been established to verify that the wetland vegetation component supports a species composition sufficient for a jurisdictional determination. Additional success criteria are dependent upon the density and growth of characteristic forest species. Specifically, a minimum mean density of 320 characteristic trees/ac must be present for the five year monitoring period. Characteristic tree species are those within the reference ecosystems (Section 5.3), elements enumerated in the planting plan, along with natural recruitment of sweet gum, red maple, loblolly bay, loblolly pine, and pond pine. Loblolly or pond pine (softwood species) cannot comprise more than 10 percent of the 320 stem/acre requirement. In addition, at least five character tree species must be present, and no species can comprise more than 20 percent of the 320 stem/acre total. Supplemental plantings will be performed as needed to achieve the vegetation success criteria. No quantitative sampling requirements are proposed for herb and shrub assemblages as part of the vegetation success criteria. Development of a forest canopy over several decades and restoration of wetland hydrology will dictate the success in migration and establishment of desired wetland understory and groundcover populations. Visual estimates of the percent cover/composition of shrub and herbaceous species and photographic evidence will be reported for information purposes. 7.5 REPORT SUBMITTAL Documentation will be submitted to the MBRT certifying completion of implementation activities. Any changes to this mitigation plan will be described in this documentation. The document will be provided within 60 days of completion of all work at the Site. Subsequently, reports will be submitted yearly to the MBRT following each assessment. Reports will document the sample transect locations, along with photographs which illustrate site conditions. Surficial well data will be presented in tabular/graphic format. The duration of wetland hydrology during the growing season will be calculated at each well, within each on-site physiographic area, and within the reference wetland site. 38 ,Y 4. The survival and density of planted tree stock will be reported. In addition, characteristic tree species mean density and average height as formatted in the Vegetation Success Criteria will be calculated. Estimates and photographic evidence of the relative percent cover of understory and groundcover species will be generated. 7.6 CONTINGENCY In the event that vegetation or hydrology success criteria are not fulfilled, a mechanism for contingency will be implemented. For vegetation contingency, replanting and extended monitoring periods will be implemented if community restoration does not fulfill minimum species density and distribution requirements. Hydrological contingency will require consultation with hydrologists and regulatory agencies if wetland hydrology restoration is not achieved during the monitoring period. Recommendations for contingency to establish wetland hydrology will be implemented and monitored until the Hydrology Success Criteria are achieved. Performance bonds have been established to guarantee fiscal resources for remediation. 39 UNITED S'T'ATES ENVIRONMENTAL PROTECTIONAGENCY • A • 4Wtit-WCWQG/KM REGION 4 Sam Nunn Atlanta Federal Center 61 Forsyth Street, S.W .-Atlanta, Geor-ia 30303 - 8960 APR 1 9 1999 i+f 'P Colonel Terry R. Youngbluth / District Engineer ATTN: Mr. Scott McLendon % 6 Wilmington District, Corps of Engineers P.O. Box 1890 Wilmington North Carolina 28402-1890 X `I . .?, A R R SUBJ: Barra Farms Cape Fear Regional Mitigation Bank; First Annual Monita` Dear Colonel Youngbluth: T he U.S. Environmental Protection Agency (EPA) has reviewed the `Wetland V?onitoring Report: Year 1 ("monitoring report"), dated November 1998, for the Barra Farms Cape Fear Regional Mitigation Bank. We regret that we will be unable to attend the May 5, 1999 field O? s A- meeting, but we would like to submit the following comments: v,'r? EPA is concerned that the vegetation monitoring daia for indiv' i -p ed, and that the data for all plots was averaged to provide the information in Tables 2 and 3. EPA is curious as to the density of tree stems in plots where only one species was planted, such as Atlantic White Cedar (AWC). If there are only 11 AW-C stems per acre present, is this particular area practically bare of vegetation, or are there other species in the same plot`? Without such information, it is difficult for EPA to determine our position on success of the site. If certain plots in the restoration areas have less than 320 stems per acre, then EPA is of the ol?i inn rh r +?? ye--?? _ p s are n_ot successful. We trust that the resource agencies will be able to receive such 00 tea"' information or view these areas during the May 5 site visit. jfv? !?? PLUS IN Furtier, Table 2 of the monitoring report indicates that Scalix nigru (Black -,villow), a s wss softwood species, represents more than 10% of the total number of trees per acre in the former cropland area. Table 3 indicates that Accr rubrum (Red mark;) exceeds 2001 of tho total treeS 11 the supplemental planting area. Although EPA recognizes that more than the required 320 stems per acre (averaged over plots) have been documented in both areas (even without including the two species mentioned above), we are concerned that almost half of the tree species planted on the forme cropland contribute less than i0 trees per acre each. Eleven desirable planted and volunteer species cumulatively contribute only 7% of the total tree species. Although we are uncertain as to how many of each species were planted, it appears that the. majority of certain species of planted trees were almost completely decimated this year, and that the remainder may not survive the required five years. EPA recommends that the sponsor closely monitor the mitioation areas to ensure that the softwood and volunteer species do not overpower the other desirable species. Further, thinning of softwood and over-dominant volunteer species, and planting of additional desirable trees may be warranted at this time. Thank you for the opportunity to comment on this project.

This appears to be the appropriate venue for discussing the Corps' role as MBRT lead after a bank has been authorized. Last month, when a potential problem at Barra Farms was discovered and reported by the Service, it was disconcerting to be told, in effect, that the Corps needs comments from the agencies before it can decide whether or not a monitoring report is adequate. In our quick site visit, we discovered that the drainage ditch and artificial levee in the area that feeds surface runoff to the stream were intact and apparently affecting hydrology. I thought the ditch and levee were to have been filled and leveled. This was not described in the report, and my concern may be the result of a misunderstanding. If it is the Corps' intent to manage mitigation banks like permits are processed, where the Corps views it's job as facilitating banks, and the burden of proof is on the resource agencies, it does not appear reasonable to let the Corps assume full responsibility. A frank disclosure of the Corps' management philosophy and goals will allow us to put realistic checks and balances into future agreements.

Scott McLendon 1 of 1 5/4/99 1:41 PM 6 _.% 7.0 MONITORING PLAN The Monitoring Plan will consist of a comparison between hydrology model predictions, reference wetlands, and wetland restoration areas on the Site. Monitoring of wetland restoration and enhancement efforts will be performed until success criteria are fulfilled. Monitoring is proposed for two wetland components, vegetation and hydrology. Wetland soils currently exist within restoration areas and monitoring is not considered necessary to verify hydric soil requirements for a jurisdictional determination. 7.1 HYDROLOGY MONITORING After hydrological modifications are being performed on the site, surficial monitoring wells will be designed and placed in accordance with specifications in U.S. Corps of Engineers', Installing Monitorina Wells/Piezometers in Wetlands (WRP Technical Note HY-IA-3.1, August 1993). Monitoring wells will be set to a depth of approximately 24 inches below the soil surface. Twenty three surficial monitoring wells (manual recording) will be installed at the Site to provide representative coverage and flow gradients extending through each of the three physiographic landscape areas (Figure 14). Four monitoring wells will also be placed within the reference wetland site in similar landscape positions, where available. Three continuous recording (RDS24) wells will also be installed on-site to provide continuous data that can be extrapolated to manual recording devices. Hydrological sampling 'will be performed on-site and within reference during the growing season (17 March to 12 November) at intervals necessary to satisfy the hydrology success criteria within the designated physiographic area (EPA 1990). In general, the wells will be sampled weekly through the Spring and early Summer and intermittently through the remainder of the growing season, if needed to verify success. 7.2 HYDROLOGY SUCCESS CRITERIA Target hydrological characteristics have been evaluated using a potential combination of three different methods: 1) regulatory wetland hydrology criteria; 2) reference groundwater modeling; and 3) reference wetland sites. Regulatory Wetland Hydrology Criteria The regulatory wetland hydrology criterion requires saturation (free water) within one foot of the soil surface for 12.5 percent of the growing season under normal climatic conditions. In some instances, the regulatory wetland hydroperiod may extend for between 5 and 12.5% of the growing season. Reference Groundwater Model The reference groundwater model forecasts that the wetland hydroperiod in interior areas of the Site will average 22% of the growing season in early successional phases. As steady state forest conditions. develop, the average wetland hydroperiod is forecast to encompass 36 40% of the growing season. Over the 31 year modeling period, the annual hydroperiod fluctuated from less than 12.5% to over 44% dependent upon rainfall patterns and successional phase. In addition, the on-site landscape includes diverse wetland geomorphology, especially near uplands and the stream channel, which are not characterized by the model. Due to wide fluctuations in modeled annual hydroperiod (< 12-44+ %), the groundwater model cannot provide a specific hydrology success criteria above the regulatory criterion (12.5%) on an annual basis. A specific success criteria such as a 22% target hydroperiod will fail in 50% of the years sampled. A success criteria of 12.5% (the regulatory criteria) will also fail in 10% of the years sampled in reference wetlands. Reference Wetland Sites Four monitoring wells will be placed in the groundwater flats reference wetland located in the northwestern periphery of Barra Farms. Wells will be also be placed in a riverine reference wetland in the Bushy Lake/Horse shoe Lake natural area dependent upon contact with the North Carolina Park and Recreation Service. These wells will provide annual hydroperiods on the organic soil flat, and riverine floodplain physiographic areas of the Site. The headwater slope physiographic area may be interpolated between the two systems. Transition zones from uplands towards the wetland interior will not be represented. Therefore, these wells will provide comparative information on interior wetlands only. The hydrology success criteria for this Site will require saturation (free water) within one foot of the soil surface for at least 50% of the hydroperiod exhibited by the reference wetland. Based on groundwater models, average wetland hydroperiods in groundwater flats will exhibit a steady, non-linear increase from 22% to 40% of the growing season during forest (post- farmland) development. This tread includes a hypothetical reduction in hydraulic conductivities and a 50% increase in surface water storage through the first 15 years of wetland development. Therefore, a goal of 50 +/-% hydroperiods relative to reference wetlands is warranted for the five year monitoring period. This 50% goal may not apply in non-organic soils as evapotranspiration may play a greater role in early successional hydroperiods than surface water storage. 7.3 VEGETATION Restoration monitoring procedures for vegetation are designed in accordance with EPA guidelines presented in Mitigation Site Type (MIST) documentation (EPA 1990) and COE Compensatory Hardwood Mitigation Guidelines (DOA 1993). The following presents a general discussion of the monitoring program. After planting has been completed in winter or early spring, an initial evaluation will be performed to verify planting methods and to determine initial species composition and density. Supplemental planting and additional site modifications will be implemented, if necessary. 37 During the first year, vegetation will receive cursory, visual evaluation on a periodic basis to ascertain the degree of overtopping of planted elements by weeds. Subsequently, quantitative sampling of vegetation will be performed between September 1 and October 31 after each growing season until the vegetation success criteria is achieved. After planting plan implementation, 0.1 acre plots will be within each restored ecosystem type. Twenty three plots will be correlated with hydrological monitoring locations to provide point- related data on hydrological and vegetation parameters. 7.4 VEGETATION SUCCESS CRITERIA Success criteria have been established to verify that the wetland vegetation component supports a species composition sufficient for a jurisdictional determination. Additional success criteria are dependent upon the density and growth of characteristic forest species. Specifically, a minimum mean density of 320 characteristic trees/ac must be present for the five year monitoring period. Characteristic tree species are those within the reference ecosystems (Section 5.3), elements enumerated in the planting plan, along with natural recruitment of sweet gum, red maple, loblolly bay, loblolly pine, and pond pine. Loblolly or pond pine (softwood species) cannot comprise more than 10 percent of the 320 stem/acre requirement. In addition, at least five character tree species must be present, and no species can comprise more than 20 percent of the 320 stem/acre total. Supplemental plantings will be performed as needed to achieve the vegetation success criteria. No quantitative sampling requirements are proposed for herb and shrub assemblages as part of the vegetation success criteria. Development of a forest canopy over several decades and restoration of wetland hydrology will dictate the success in migration and establishment of desired wetland understory and groundcover populations. Visual estimates of the percent cover/composition of shrub and herbaceous species and photographic evidence will be reported for information purposes. 7.5 REPORT SUBMITTAL Documentation will be submitted to the MBRT certifying completion of implementation activities. Any changes to this mitigation plan will be described in this documentation. The document will be provided within 60 days of completion of all work at the Site. Subsequently, reports will be submitted yearly to the MBRT following each assessment. Reports will document the sample transect locations, along with photographs which illustrate site conditions. Surficial well data will be presented in tabular/graphic format. The duration of wetland hydrology during the growing season will be calculated at each well, within each on-site physiographic area, and within the reference wetland site. 38 The survival and density of planted tree stock will be reported. In addition, characteristic tree species mean density and average height as formatted in the Vegetation Success Criteria will be calculated. Estimates and photographic evidence of the relative percent cover of understory and groundcover species will be generated. 7.6 CONTINGENCY In the event that vegetation or hydrology success criteria are not fulfilled, a mechanism for contingency will be implemented. For vegetation contingency, replanting and extended monitoring periods will be implemented if community restoration does not fulfill minimum species density and distribution requirements. Hydrological contingency will require consultation with hydrologists and regulatory agencies if wetland hydrology restoration is not achieved during the monitoring period. Recommendations for contingency to establish wetland hydrology will be implemented and monitored until the Hydrology Success Criteria are achieved. Performance bonds have been established to guarantee fiscal resources for remediation. 39 EcoScience 10 December 1998 Ron Ferrell N.C. Wetland Restoration Program P.O.

A third vegetation survey was conducted in April of 2000 to monitor natural recruitment of vegetation at Barra and evaluate the survival of seedlings planted in February. This report summarizes the results of this survey and compares the data to the drastically different results of the vegetation survey conducted in November of 1999. Because of natural recruitment, supplemental planting, and the installation of drainage pipes to control water levels, Barra Farms now meets and exceeds the vegetation success criteria required in the mitigation plan.

Wildlife Resources Commission r SUPPLEMENTAL ACTIONS TAKEN AT BARRA FARMS CAPE FEAR REGIONAL MITIGATION BANK 1999-2000 Prepared for: Ecobank Prepared by: Land Management Group, Inc. Wilmington, NC March, 2000 SUPPLEMENTAL ACTIONS TAKEN AT BARRA FARMS CAPE FEAR REGIONAL MITIGATION BANK 1999-2000 The following is a list of actions that have been taken to improve the quality of monitoring and insure future mitigation success at Barra Farms: 1. Installation of six 18" diameter drainage pipes along the north section of Barra to alleviate ponding (Figure 1). The pipes were installed in October of 1999 to reduce the standing water created by rainfall from hurricanes and from any future heavy rain events. Ponded water will be lowered only during and/or after extreme climatic rainfall events after which ponding could be detrimental to the growth of survival of character species. The pipes will not allow groundwater levels to recede below the wetland hydrology thresholds and can be plugged in dry periods to allow percolation into the wetland before standing water is released. 2. The percentage of Barra being sampled for vegetation was increased in Year 2 monitoring. In Year 1 monitoring, 24 plots, each 0.05 acre in size, were sampled resulting in a total of 1.2 acres surveyed. In order to get a larger sample of representative vegetation and to pinpoint the location of areas not meeting the vegetative success criteria, the sampling area was increased in 1999. In Year 2 monitoring, 34 plots that were each 0.1 acre in size were sampled resulting in 3.4 total acres surveyed. This is a 283% increase in sampling size between Year 1 and Year 2. These 34 plots include 19 of the original 24 plots plus an additional 15 plots randomly placed in areas generally lacking plots. 3. In December of 1999, a subcontractor hired by ECOBANK installed 3 new RDS monitoring wells at Barra to get a more precise and continuous account of hydrology. A total of five RDS wells now read hydrology data on-site and 2 RDS wells are located at reference sites. 4. In January of 2000, the mouth of the mitigation stream at Barra was cleaned of debris such as fallen limbs and snags to increase stream flow and further reduce standing water in this area (Figure 2). 5. Supplemental planting at the Barra Farms Mitigation Bank was performed February 8-11, 2000. Twelve species that have shown an ability to survive at Barra (Table 1) were planted across the groundwater flats and headwater slope habitats, which comprise approximately 362 acres of this site (Figure 3). Seedlings that were approximately 2 years old were purchased from the North Carolina Division of Forest Resources Nursery in Goldsboro, NC (Figure 4) and were evenly distributed across the former crop land at Barra (Figures 5 and 6). However, in wetter areas, such as the headwater slope habitat, a greater number of bald cypress and water tupelo were planted, since these species are better adapted to wet conditions. Planting actions were closely monitored by Land Management Group, Inc. personnel. A total of 43,300 seedlings planted across 362 acres resulted in approximately 120 trees/acre (- 20-foot spacing). Since an average of 241 characteristic trees/ac (average of groundwater flats and headwater slope habitats) were observed in Year 2 monitoring, this supplemental planting increased tree density to 361 trees/acre. These trees, in addition to new volunteers and the established trees already present, will help Barra achieve the vegetative success criterion of 320 characteristic trees/acre over the required monitoring period.

Since the continuous monitoring stream gauges placed in the reference and restoration streams in 1999 have been somewhat unreliable, staff gauges will be replaced and used as a backup measure of stream flow. The staff gauges will insure continuous collection of flow data and will allow a more accurate assessment of stream mitigation. w e• J ?y '?• ?"- .t'• + '1?? i.ib,?'ik"'?f. r?!" ;! ??Mp??'..r-,-: i_N..,?tFA??.s? ?.•t?f.??.?Rr Y ?. °? , ?'y. r L -iT`SS ter.: ^?

Ecobank Cumberland County, NC Land Management Group, Inc. PROGRESS REPORT: Results of April, 2000 vegetation monitoring at Barra Farms Cape Fear Regional Mitigation Bank Prepared for: Ecobank Prepared by: Land Management Group, Inc. Wilmington, NC May 1, 2000 Success criteria for the Barra Farms Mitigation Plan include a minimum mean density of 320 characteristic trees/acre. At least five character tree species must be present, and no hardwood species can comprise more than 20 percent of the total number of stems/acre total. Softwood species cannot comprise more than 10 percent of the total number of stems/acre. The Year 2 Monitoring Report found that neither the groundwater flats nor headwater slope community types met these vegetation success criteria. Supplemental planting of 43,300 seedlings occurred during February of 2000 to increase survivability to acceptable levels. A third monitoring survey was conducted in April of 2000 to monitor the progress of these seedlings. The results of both surveys are given below. November, 1999 SURVEY (2' Monitoring Report) Groundwater Flats Within the groundwater flats habitat, 27 woody species were surveyed among the 29 plots. Of the 27 species, 19 were tree species and 8 were shrub species. Of the tree species, 11 were planted and 8 were volunteer. All shrubs were volunteer. Most common species included bald cypress (Taxodium distichum), black willow (Salix nigra), red maple (Acer rubrum), and swamp tupelo and/or water tupelo (Nyssa biflora, N. aquatica). The vegetation observed within groundwater flats averaged 269 stems/acre with approximately 128 stems/acre from planted species. Because 435 stems/acre were planted in these areas in the winter of 1998, the survival rate is estimated at approximately 29% after the second growing season. When using the number of trees/acre by species that can be applied to the total number of stems/acre criterion (<_ 20% of 320 stems/acre for hardwoods and <_ 10% of 320 stems/acre for softwoods), the total number of trees that can be counted per acre is 255.4 (see Table 4, column 5). Headwater Slope A total of 8 woody species were found within this habitat, of which 4 were planted and 4 were volunteer. The most common species include black willow (Salix nigra), swamp tupelo and /or water tupelo (Nyssa biflora, N. aquatica), red maple (Acer rubrum), and bald cypress (Taxodium distichum). This vegetation averaged 317 stems/acre, with 130 stems/acre from planted species. Therefore, the survival rate of trees planted in the headwater slope is 30%.When success criteria percentages are used (_< 20% of 320 stems/acre for hardwoods and <_ 10% of 320 stems/acre for softwoods), the total number of trees that can be counted per acre is 227.5 (see Table 5, column 5). April, 2000 SURVEY (3rd Monitoring Report) Groundwater Flats Within the groundwater flats habitat, 26 woody species were surveyed among the 30 plots. Of the 26 species, 18 were tree species and 8 were shrub species. Of the tree species, 11 were planted and 7 were volunteer. All shrubs were volunteer. Most common species included bald cypress (Taxodium distichum), black willow (Salix nigra), red maple (Acer rubrum), and swamp tupelo and/or water tupelo (Nyssa Mora, N. aquatica). The vegetation observed within groundwater flats averaged 485.1 stems/acre with approximately 259 stems/acre from planted species. When using the number of trees/acre by species that can be applied to the total number of stems/acre criterion (_< 20% of total stems/acre for hardwoods and s 10% of total stems/acre for softwoods), the total number of trees that can be counted per acre is 456.6 (see Table 6, column 5). Headwater Slope A total of 14 woody species were found within this habitat, of which 9 were planted and 5 were volunteer. The most common species include black willow (Salix nigra), swamp tupelo and /or water tupelo (Nyssa biflora, N. aquatica), red maple (Acer rubrum), and bald cypress (Taxodium distichum). This vegetation averaged 612.5 stems/acre, with 300 stems/acre from planted species. When success criteria percentages are used (s 20% of total stems/acre for hardwoods and _< 10% of total stems/acre for softwoods), the total number of trees that can be counted per acre is 436.2 (see Table 7, column 5). Summary In 11/99, a mean density of 255.4 stems/acre was found across 27 character wetland species within the groundwater flats habitat, with an average of 3.9 species/plot. In 4/00, a mean density of 456.6 stems/acre (adjusted) was observed across 26 character wetland species, with an average of 6.6 species/plot. In the headwater slope habitat in 11/99, a mean density of 227.5 stems/acre was found across 8 wetland species, with an average of 4 species/plot. In April, 2000 the headwater slope habitat had a mean density of 436.2 stems/acre (adjusted) across 14 wetland species, with an average of 7.5 species/plot. Both habitats doubled their stem counts as well as their species diversity. As a result of natural recruitment, supplemental planting, and the installation of drainage pipes to control water levels, both habitat types now contain more than 320 stems/acre and over 5 wetland species/plot. Therefore, the Barra Farms Mitigation Bank has met and exceeded the wetland vegetation success criterion. 2 Vf 4-4 O V O ?D 10 00 [- t!1 h h ?

The bank comprises 623 acres located along the headwaters of Harrison Creek in Cumberland County (Figure 1). Stream and wetland restoration/enhancement activities were completed in the winter of 1997-1998 as described in the detailed mitigation plan. A mitigation banking instrument has also been prepared and approved through ongoing coordination with the mitigation banking review team (MBRT) as outlined in the Federal Guidance on the Establishment, Use, and Operation of Mitigation Banks (60 FR 12286- 12293, 1995). Hydrological and vegetation monitoring are important components of a successful mitigation plan and are required for release of compensatory mitigation credits. The Barra Farms monitoring plan requires annual monitoring for a five year period and analysis of the data to evaluate success in the establishment and maintenance of diagnostic stream and wetland parameters. In the Year 2 Monitoring Report, certain changes have been made to the monitoring protocol in order to more accurately evaluate success criteria. In 1999, a larger percentage of Barra was sampled for vegetation and three-more RDS continuous-monitorina wells were installed to Lyather additional data. It is proposed that the manual monitoring of hydrology be phased out and v these RDS wells. Finally, evaluation of the stream..mitijzatian m-U bz-=dQr=d in a ' separate effort due April 2000, after one dull year of stream flow data has been collected. This document represents the Annual Wetland Monitoring Report (AWMR) for Year 2 of the monitoring plan. Monitoring has been performed throughout the 1999 growing season for hydrology, vegetation, and stream parameters, consisting primarily of a comparison between hydrology model predictions, reference wetlands, and wetland restoration areas in the Bank. ' Subsequently, the success criteria are analyzed and verified to facilitate issuance of mitigation credit designated in the MBI at the end of Year 2 monitoring. ' Since the restoration at Barra Farms began, standing water has accumulated on certain sections of the site. This ponding was primarily caused by heavy rainfall in both 1998 and 1999, aeration and compaction of the soil, and natural swales in the topography. Steps have been taken to alleviate ' this ponding, including the installation of six drainage pipes and clearing debris from the mouth of the mitigation stream. Because it was anticipated that seedling survivability would be low due to this ponding, Year 2 monitoring was used to pinpoint areas at Barra Farms that may require ' supplemental planting, in addition to evaluating success criteria. 1 1 i i i i i i i i i G . r ; E - rPow! ,?-: -i •ur;uo ° ii - '/ '??v° w p. !? f/ ,•?? ,. ?/« ' ? y to ?•}\ `/ ' ? if i, '?' n ?

Figure 2 depicts the approximate location of monitoring wells in the Bank. Two continuous recording (RDS24) wells were also placed on-site to provide continuous data that can be extrapolated to manual recording devices. Monitoring wells were installed and downloaded by a subcontractor in accordance with specifications in U. S. Corps of Engineers' Installing Monitoring Wells / Piezometers in Wetlands (WRP Technical Note HY-IA-3.1, August 1993). The monitoring wells are set to a depth of approximately 24 inches below the soil surface. Five manual monitoring wells were placed in reference wetlands to compare hydrology between the Bank and relatively undisturbed wetlands in the region. Three wells are located in the reference groundwater flats along the northwestern periphe oo '?a Farms. Two additional wells are located in the reference rive ' wetland along Colly Creek in the Bushy Lake/Horse Shoe T ake Natural Area These wells provide comparative annual hydroperiods within the organic soil flat and riverine floodplain physiographic areas of the site. The headwater slope physiographic area is interpolated from the two adjacent systems as described in the mitigation plan and the MBI. Hydrological data continue to be collected at weekly intervals on-site and within the reference sites. The data extending from March 11, 1999 (first reading within the growing season) to November 13, 1999 (last reading within the growing season) have been utilized in this Year 2 AWMR. 2.2 Monitoring Results The raw well data are depicted in hydrograph and tabular format in Appendix B. Wetland hydrology criteria in number of consecutive days and percent of the growing season is also summarized in Table 1. Line intersection at 12 inches below the surface was used as the cut off for wetland hydrology, following the regulatory wetland criterion requiring saturation (free water) within one foot of the soil surface. As in Year 1 monitoring, groundwater levels were highest in early spring, followed by dry periods during summer months. Severe rain events associated with tropical storm systems in August and September significantly elevated groundwater and surface water levels near the end of the Year 2 monitoring period. Well data have been subdivided into three wetland physiographic wetland types: 1) groundwater flats (GF); 2) headwater slopes (HS); and 3) riverine floodplains (RF) 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Groundwater Flats (GF) ' Three wells located within reference groundwater flats provide a general indication of the average 1999 hydroperiod on groundwater flats supporting steady state forest structure ' and organic soils. Data indicate that wetland hydrology on reference groundwater flats habitat in the region was maintained during 40% of the growing season. The groundwater flats data from the restoration wetland area had an average wetland hydrology spanning 36% of the growing season (Table 1). This hydrology ranged from ' 11% to 53%. Year 1 monitoring indicated that the wetland hydrology within this habitat correlated with vegetation cover and soil organic matter content, with the wettest hydrology in areas of high organic matter and low vegetation cover and the driest hydrology in areas with mineral soil flats. Year 2 monitoring results were similar, with organic soil flats on former farmland supporting the longest wetland hydrology, 41% of the growing season. However, mineral soil flats on former farmland exhibited wetland ' hydrology longer (34%) than those of organic soil flats that support dense successional (pocosin-like) vegetation (30%), which does not correlate with the results of Year 1 monitoring. The short length of wetland hydrology on organic flats with pocosin habitat is ' mostly due to the readings of one well on this habitat. Well 21 was saturated within 12 Amy Q inches of the surface durin onl 110/- of the o eason an m v1 v ed to meet t e wet and hydrology criterion (at least 12.5% of growing season). If the data from ' this one well were taken out of the calculations, the average pocosin habitat wetland hydrology would increase to 36% of the growing season and would probably be more indicative of its normal hydrology. ' Riverine Floodplains (RF) Two wells are located in reference riverine floodplain habitat. The data from these wells ' indicate that the average wetland hydrology for small stream swamps is approximately 42% of the growing season. Reference data demonstrate that, as in Year 1 monitoring, hydrology appears to decrease in proximity to stream channels and increase along outer floodplain fringe influenced by riparian groundwater discharge, the lack of discharge outlets, and backwater flooding. Data fr om the two wells located in restoration riverine floodplain habitat indicate that rte- wetland hydrology averaged 31 % of the growing season. Both wells have the same ' n C umber of consecutive saturation days, and, therefore, no difference in hydrology due to proximity of well to stream channel was noted. ' Headwater Slopes (HS) Reference wetland hydrology for the headwater slope habitat have been simulated by ' averaging wetland hydrology exhibited by adjacent riverine floodplain and groundwater ' flats. The average amount of time the headwater slope habitat met wetland hydrology was 41 % of the growing season and ranged from 40% (groundwater flats) to 42% (riverine ' floodplain). Headwater slope in the restoration wetlands supported wetland hydrology averaging 36% ' of the growing season and ranged from 28 to 51 %. As in Year 1 monitoring, the range appeared to be influenced primarily by landscape position within the headwater storage area and vegetation cover. The shortest percentage of time meeting the wetland hydrology criterion (28%) occurred in an area dominated by early successional or pocosin habitat (W19) and in former farmland areas (31%). However, the wetland hydrology in forested areas was considerably longer (38% and 51% of growing season). ' 2.3 Evaluation of Success Criteria Success in the restoration of wetland hydrology in the Bank requires saturation (free ' water) within one foot of the soil surface for at least 50% of the time the reference habitat achieved wetland hydrology. This criterion is applied separately to each of the habitats. ' The reference groundwater flats, riverine floodplain, and headwater slope habitats exhibited wetland hydrology for a period averaging 40%, 42%, and 41 %, respectively. In the Bank, restoration wetlands supported wetland hydrology averaging 36% (90% of ' reference), 31% (73% of reference), and 36% (87% of reference), respectively. Therefore, each habitat evaluated at Barra fulfilled the wetland hydrology criteria during 1999. ? C2 M 7 Table 1. Summary of 1999 hydrology monitoring data at Barra Farms.

In 1998, 24 plots (each 0.05 acre in size) were sampled, resulting in a total of 1.2 acres surveyed. In order to get a larger sample of representative vegetation and to pinpoint the location of areas not meeting the vegetative success criteria, the sampling area was increased in 1999. In Year 2 monitoring, 34 plots that were each 0.1 acre in size were sampled resulting in 3.4 total acres surveyed. This is a 283% increase in sampling size between Year 1 and Year 2. These 34 plots include 19 of the original 24 plots plus an additional 15 plots randomly placed in areas generally lacking plots (Figure 2). The center of each plot was permanently established with a labeled, white polyvinyl chloride (PVC) pipe marked with pink and black striped flagging. In the winter of 1998, two different planting densities were used at Barra Farms, depending on whether the area was crop land or forested prior to planting. Crop land was largely devoid of vegetation and received a full planting which consisted of 435 stems/acre. Forested areas already contained a large amount of woody vegetation and only received a supplemental planting of 70 Year 1 monitoring, the vegetation in bo i areas was samp e . However, in Year 2, the supplemental planting areas were not surveyed because vegetation was thick, making it difficult to distinguish planted vegetation from already existing vegetation. Furthermore, wetland vegetation has already been determined to be present at these sites from Year 1 monitoring and additional planting will not occur. i i i i i i i Therefore, all 34 plot centers were set up and sampled in areas that received a "Full Planting" of 435 stems/acre. This comprised 376 acres of the 623-acre Bank. Plot centers were placed within three community-types at Barra Farms. Twenty-nine plots were located in groundwater flats, which represent 324 acres. Four sample plots were located within the headwater slope habitat, which represents approximately 38 acres. Finally, one plot was placed in the uplands habitat, which comprises 14 acres. No plots were set up within the riverine habitat since these areas are all forested and received supplemental planting. At each plot center, woody species within a 37.2-foot radius of the plot center were flagged, identified, and measured for height. If diameter a r as i ht was equal to or greater than one inch, that was recorded as well. In most c ,clumps of multiple black willow (Salix nigra) stems originating from a common root source were counted as a single stem. In addition, since water tupelo (Nyssa aquatica) and swamp tupelo (N?ssa bf ora) cannot be distinguished from each other as seedlings, these Nyssa specie_ s. were grouped into one category in the data analysis. .' ti Allk ej?? 9 i 1 3.2 Monitoring Results Herbaceous Vegetation A total of 21 herbaceous species were identified at the 34 sample plots (Appendix Q. The most common were dog fennel (Eupatorium capillifolium), broomsedge (Andropogon virginicus), woolgrass (Scirpus cyperinus), and cattail (Typha latifolia). Plots located in groundwater flats generally had more dog fennel than plots in headwater slope habitat, indicating that the flats, whose elevation is on average a foot or two higher than the headwater slope, were able to dry out during the summer months, allowing this upland species to grow. Headwater slope habitat generally contained a larger amount of cattail and woolgrass, since it remained ponded for most of the year. However, in plots heavily ponded, both woody and herbaceous vegetation were relatively scarce (Plots 4, 9, 26, 27, 30, 31, 32). Groundwater Flats Within the groundwater flats habitat, 27 woody species were surveyed among the 29 plots. Of the 27 species, 19 were tree species and 8 were shrub species. Of the tree species, 11 were planted and 8 were volunteer. All shrubs were volunteer. Most common species included bald cypress (Taxodium distichum), black willow (Salix nigra), red maple (Acer rubrum), and swamp tupelo and/or water tupelo (Nyssa biflora, N. aquatica). The vegetation observed within groundwater flats averaged 269 stems/acre with approximately 128 stems/acre from planted species. Because 435 stems/acre were planted in these areas in the winter of 1998, the survival rate is estimated at approximately 29% after the second growing season. When using the number of trees/acre by species that can be applied to the 320 stems/acre criterion (<_ 20% of 320 stems/acre for hardwoods and <_ 10% of 32 stems/acre for softwoods), the total number of trees that can be counted per acr s 255.4 (see Table 2, column 5). Headwater Slope A total of 8 woody species were found within this habitat, of which 4 were planted and 4 were volunteer. The most common species include black willow (Salix nigra), swamp tupelo and /or water tupelo (Nyssa biflora, N. aquatica), red maple (Acer rubrum), and bald cypress (Taxodium distichum). This vegetation averaged 317 stems/acre, with 130 stems/acre from planted species. Therefore, the survival rate of trees planted in the headwater slope is 30%.When success criteria percentages are used (<_ 20% of 320 stems/acre for hardwoods and _< 10% of 320 stems/acre for softwoods), the total number 10 74re e-.s ' of trees that can be counted per acre 227.5 (,s e Table 3, column 5). ' 3.3 Evaluation of Success Criteria Success criteria for the Barra Farms Mitigation Plan include a minimum mean density of ' 320 characteristic trees/acre. At least five character tree species must be present, and no hardwood species can comprise more than 20 percent of the 320 stems/acre total (64 stems). Softwood species cannot comprise more than 10 percent of the 320 stems/acre ' total (32 stems). Tables 2 and 3 show the number of trees/acre by species that can be applied to the 320 stems/acre criterion. For groundwater flats, a mean density of 255.4 stems/acre is found across 27 character wetland species, with an average of 3.9 species/plot. In the headwater ' slope habitat, a mean density of 227.5 stems/acre is found across 8 wetland species, with an average of 4 species/plot. Neither of these wetland commu tty types meets the vegetation acce -table evels. However, it should be noted that these wetland community types do contain a wide range of woody and herbaceous species diversity, a trait indicative of natural succession. No invasive or exotic species were observed. I 11 Table 2. Woody species found in groundwater flats habitat, average number of trees/acre, and the number of trees allowed in success criteria.

A separate stream monitoring report will be written after more information has been gathered ' on each of these parameters (April, 2000). Below is a description of the success criterion and a list of data collected thus far for each component. 1 4.1 In-Stream Flows I 0 I Continuous monitoring stream gauges have been placed in the reference stream and the mitigation stream to compare in-stream flows. The gauge data are collected as mean daily flows for velocity (ft/second) and discharge (ft3/second). The success criterion is that the mitigation stream reach supports mean daily flows per unit of drainage area equal to or exceeding the mean daily flows per unit of drainage area within the reference stream reach. The reference stream reach supports an approximate 6.7 mil drainage area while the mitigation stream reach supports an approximate 2.5 mil drainage area (37% of reference). Therefore, mean daily flows in the mitigation reach must be equal to, or exceed, 37% of the mean daily flows in the reference stream. Synchronized data collection for the two streams began in April of 1999. The cnhenntractnr ,re to mnrn .ter a streams noticed no measura a ow om April to Au_ Beginning August , 1999, the continuous monitoring gauges began reading stream flow data and took over the data collection. The data collected thus far by the subcontractor and the gauges are presented in Figures 3 and 4. However, in order to analyze one full year of stream flow data, the stream monitoring report will be submitted at the end of April, 2000. 4.2 Biological Stream Attributes The mitigation plan requires biological stream attributes to be measured annually at the mitigation stream and at the reference stream between April 15 and May 15 of each year. Aquatic surveys must record the presence/absence of macro-invertebrates, reptiles, amphibians, and fish species populations at these two streams. The success criterion for stream restoration requires that the type and number of species identified in the mitigation reach must be equal to, or greater than, the type and number of species identified in the reference reach in each successive monitoring year. The number and type of benthic macro-invertebrates found in the mitigation stream at 14 H 1 Barra and at the reference stream were measured on June 4, 1999. These results are presented in Table 4. There is approximately an equal number of taxa in each stream, yet the restoration stream has anywhere from 2.5 to 5 times more organisms than the reference stream. In addition to these results, a description of the reptiles, amphibians, and fish found in both streams will also be included in the stream monitoring report. 4.3 Stream Geometry Components of stream geometry were measured in May of 1997 to obtain baseline, pre- restoration conditions and then again in 1998 to obtain post-restoration conditions (Table 5). Success criteria were fulfilled in the Year 1 monitoring because the channel and adjacent floodplain support characteristics of a C stream type with a cross-sectional area progressing towards the projected post-restoration condition. The mitigation plan calls for annual fall monitoring that includes development of a channel plan view, three channel cross-sections, pebble counts, and a water surface profile of the channel. The stream will subsequently be classified according to stream geometry and substrate. These measurements will be collected and summarized in the stream monitoring report due out in April. The issuance of stream restoration credits will be discussed with the MBRT upon completion of the Year 2 Stream Monitoring Report in April, 2000. ?Lx 15 Figure 3.

Late January to early February experienced above-average rainfall (see rainfall chart in 1 Appendix B) that caused ponding over much of Barra (Photo page 1). Depth of water ranged from saturation to elevations approximately one foot above the soil surface. These ponded areas may be natural swales within this Carolina bay system. Low elevations will ' naturally collect more rainwater, have a higher groundwater level, and support vegetation adapted to wet conditions, such as bald cypress, water tupelo, and black willow. Another possibility for this standing water may be that these lower elevations were not present when ' the ditches were filled, but since that time the soil at the mouth of the stream has compacted and subsided from oxidation and the weight of the ponded water, forming dips in the landscape. ' This standing water remained until June of 1999. Drier weather brought with it lower groundwater levels (see wetland hydrology data in Appendix B) and the growth of ' numerous herbaceous plants. In the wetter areas, such as the headwater slope habitat, hydrophytic species such as sedges, cattails, and woolgrass dominated. In drier areas within the groundwater flats habitat, more broomsedge and dog fennel were found. ' During the summer months, much of eastern United States including North Carolina ' experienced a drought. This dry weather substantially reduced groundwater levels at Barra (Photo page 2). Water tables generally remained deeper than two feet below ground level until September 15, 1999. ' Several hurricanes hit North Carolina in September and October and produced large amounts of rainfall that, again, inundated most of Barra Farms. This rainfall (see Appendix ' B) resulted in a 500-year flood across eastern North Carolina and produced standing water on both the former crop land on-site and forested sections within the reference site (Photo pages 3 and 4). During periods of standing water, a variety of wildlife that are adapted to ' aquatic wetland habitats were noted, such as the great blue heron (Ardea herodias), wood duck (Aix sponsa), mallard (Anas platyrhynchos), belted kingfisher (Megaceryle alcyon), snapping turtle (Chelydra serpentina), and mud turtle (Kinosternon subrubrum). ' " diameter) were placed through the northern farm In October, six drainage pipes (18 road/berm to drain standing water from the restoration areas (Photo page 5). These pipes ' had ditches 50 feet long and up to 2 feet deep draining water into them. Despite these efforts, water levels were still above ground in some places during November and December. To further alleviate the standing water, in January of 2000 the mouth of the ' restoration stream was cleared of debris, such as tree limbs and snags, to allow the water in this area to flow through it and out of Barra (Photo pages 6 and 7). ' 19 I ' A comparison of data and photos from 1998 and 1999 indicates a major difference in the survivability of vegetation at Barra between those years. In 1998, in spite of an ' unprecedented wet winter (El Nino) and a fairly dry summer, the average seedling survival rate was 83% and an average of 733 trees/acre were observed. However, in 1999, heavy ' rainfall and a dry summer increased seedling mortality of both planted and volunteer species. Only 293 trees/acre were observed in 1999. Since both years experienced heavy rainfall and a summer drought, it may be the length of the summer drought or the timing of ' the heavy rains that caused the difference in survivability from one year to the next. 1999 experienced a longer drought and wet weather during both the winter and late summer. 1999 also experienced several hurricanes which, in addition to rain, brought strong winds ' that may have increased mortality. Other possible reasons for the difference may be changes in the sampling methods used or a difference in the intensity of herbivory. u 0 I 20 ' 5.2 Photographs of Barra Farms During 1999-2000. 0 L 11 21 i i i i Picture taken from station #4 r • :: N?,?±.n f i ? i i <'. ? r ?'•?' . , „i x.?h?' ,,,...-any . t.1- A4 a a 4 :.? ,..? a 40 Picture taken from station #5. l 1, Hea?n/ rainfall during the winter of 1999 caused Basra Farms ponding over sections of Barra Farms, Cumberland County, NC 22 Land Management Group, Inc, 1 1 1 1 1 1 1 1 1 i 1 1 1 1 1 • rT' ?g.IlMe a Picture taken from station #4, r ?! tl Picture taken from station #7- 2.

Success in the restoration of wetland hydrology in the Bank requires saturation (free water) within one foot of the soil surface for at least 50% of the time that the reference wetland exhibited wetland hydrology. The reference groundwater flats, riverine floodplain, and headwater slope habitats exhibited wetland hydrology for a period averaging 40%, 42%, and 41%, respectively. In the Bank, restoration wetlands supported wetland hydrology averaging 36% (90% of reference), 31% (73% of reference), and 36% (87% of reference), respectively. Since hydrology criteria have been satisfied for the past two years of monitoring and because there are now five RDS continuous monitoring wells located on site, ECOBANK proposes to decrease the intensity of manually monitoring wells. During the third monitoring year, ECOBANK will manually monitor wells once a month. If hydrology continues to meet success criteria, manual monitoring will be discontinued after the third year. According to the mitigation plan, at least 320 trees/acre must survive in order to meet success criteria. During the November 1999 monitoring, groundwater flats habitat had 255 stems/ac survive and headwater slope habitat supported 227 stems/ac. Contingency planting that occurred February 8 - 11 2000 added-43,300 more seedlings across 362 acres at Barra (see Appendix E). ese plantings increased tree density to an averag-F-UFTM? trees/acre, which meets vegetation success criteria. Through this contingency planting, remedial actions to alleviate ponding, and the natur vegetative succession that is currently taking place at Barra, vegetation success criteria will continue to be achieved in the coming years. A stream monitoring report will be submitted at the end of April, 2000, after one year of stream flow data has been collected. 29 0 n C 0 0 APPENDIX A: Mitigation Credit Release Schedule C i zz m w z O Lu Q CD U Cl) cW W Q Z O 00 J W W o CC cc W ~ ui cr- w LL 2 LU w 0 z O a U ?

Summary of Monitoring Plan 1.0 MONITORING PLAN ' The Monitoring Plan will consist of a comparison between hydrology model predictions, reference streams and wetlands, and restoration areas on the Site. Stream restoration monitoring will be performed through analysis of in-stream flows, stream geometry, and biological stream attributes. ' Wetland monitoring will entail analysis of two primary parameters: vegetation and hydrology. Monitoring of restoration and enhancement efforts will be performed until success criteria are fulfilled. 1.1 HYDROLOGY MONITORING After hydrological modifications are being performed on the site, surficial monitoring wells will be ' designed and placed in accordance with specifications in U.S. Corps of Engineers', Installing Monitoring Wells/Piezometers in Wetlands (WRP Technical Note HY-IA-3.1, August 1993). Monitoring wells will be set to a depth of approximately 24 inches below the soil surface. ' Twenty three surficial monitoring wells manual recording) will ( ) be installed at the Site to provide ' representative coverage and flow gradients extending through each of the three physiographic landscape areas (Figure 2). Four monitoring wells will also be placed within the reference wetland site in simtlarlandscape positions, where available. Three continuous recording (RDS24) wells will ' also be installed on-site to provide continuous data that can be extrapolated to manual recording devices. ' Hydrological sampling will be performed on-site and within reference during the growing season (17 March to 12 November) at intervals necessary to satisfy the hydrology success criteria within the designated physiographic area (EPA 1990). In general, the wells will be sampled weekly through ' the Spring and early Summer and intermittently through the remainder of the growing season, if needed to verify success. 1.2 HYDROLOGY SUCCESS CRITERIA Target hydrological characteristics have been evaluated using a potential combination of three different methods: 1) regulatory wetland hydrology criteria; 2) reference groundwater modeling; and 3) reference wetland sites. ' Regulatory Wetland Hvdrolou Criteria The regulatory wetland hydrology criterion requires saturation (free water) within one foot of the soil surface for 12.E percent of the growing season under normal climatic conditions. In some instances, the regulatory wetland hydroperiod may extend for between and 12.5% of the growing season. Reference Groundwater Model ' The reference groundwater model forecasts that the wetland hydroperiod in interior areas of the Site will average 22%O of the growing season in early successional phases. As steady state forest conditions develop, the average wetland hydroperiod is forecast to encompass 4017o of the growing ' season. Over the 31 year modeling period, the annual hydroperiod fluctuated from less than 12.5% to over 4417o dependent upon rainfall patterns and successional phase. In addition, the on-site ' Pale I of 5 landscape includes diverse wetland geomorphology, especially near uplands and the stream channel which are not characterized by the model. I I Due to wide fluctuations in modeled annual hydroperiod (<12-44+%), the groundwater model cannot provide a specific hydrology success criteria above the regulatory criterion (12.5%) on an annual basis. A specific success criteria such as a 22% target hydroperiod will fail in 50% of the years sampled. A success criteria of 12.5% (the regulatory criteria) will also fail in 10% of the years sampled in reference wetlands. y Reference Wetland Sites Four monitoring wells will be placed in the groundwater flats reference wetland located in the northwestern periphery of Barra Farms. Wells will be also be placed in a riverine reference wetland in the Bushy Lake/Horse shoe Lake natural area dependent upon contact with the North Carolina Park and Recreation Service. These wells will provide annual hydroperiods on the organic soil flat, and riverine floodplain physiographic areas of the Site. The headwater slope physiographic area may be interpolated between the two systems. Transition zones from uplands towards the wetland interior will not be. represented. Therefore, these wells will provide comparative information on interior wetlands only. The hydrology success criteria for this Site will require saturation (free water) within one foot of the soil surface for at least 50% of the hydroperiod exhibited by the reference wetland. Based on groundwater models, average wetland hydroperiods in groundwater flats will exhibit a steady, non-linear increase from 22% to 40% of the growing season during forest (post-farmland) development. This trend includes a hypothetical reduction in hydraulic conductivities and a 5090 increase in surface water storage through the first 15 years of wetland development. Therefore, a goal of 50 +/-% hydroperiods relative to reference wetlands is warranted for the five year monitoring period. This 50% goal may not apply in non-organic soils as evapotranspiration may play a greater role in early successional hydroperiods than surface water storage. 1.3 VEGETATION Restoration monitoring procedures for vegetation are designed in accordance with EPA guidelines presented in Mitigation Site Type (MIST) documentation (EPA 1990) and COE Compensatory Hardwood Mitigation Guidelines (DOA 1993). The following presents a general discussion of the monitoring program. ' After planting has been completed in winter or early spring, an initial evaluation will be performed to verify planting methods and to determine initial species composition and density. Supplemental planting and additional site modifications will be implemented, if necessary. During the first year, vegetation will receive cursory, visual evaluation on a periodic basis to ascertain the degree of overtopping of planted elements by weeds. Subsequently, quantitative ' sampling of vegetation will be performed between September 1 and October 31 after each growing season until the vegetation success criteria is achieved. Page 2 of After planting plan implementation, 0.1 acre plots will be within each restored ecosystem type. Twenty three plots will be correlated with hydrological monitoring locations to provide point-related data on hydrological and vegetation parameters. 1.4 VEGETATION SUCCESS CRITERIA Success criteria have been established to verify that the wetland vegetation component supports a species composition sufficient for a jurisdictional determination. Additional success criteria are dependent upon the density and growth of characteristic forest species. Specifically, a minimum mean density of 320 characteristic trees/ac must be present for the five year monitoring period. Characteristic tree species are those within the reference ecosystems, elements enumerated in the planting plan, along with natural recruitment of sweet gum, red maple, loblolly bay, loblolly pine, and pond pine. Loblolly or pond pine (softwood species) cannot comprise more than 10 percent of the 320 stem/acre requirement. In addition, at least five character tree species must be present, and no species can comprise more than 20 percent of the 320 stem/acre total. Supplemental plantings will be performed as needed to achieve the vegetation success criteria. No quantitative sampling requirements are proposed for herb and shrub assemblages as part of the vegetation success criteria. Development of a forest canopy over several decades and restoration of wetland hydrology will dictate the success in migration and establishment of desired wetland understory and groundcover populations. Visual estimates of the percent cover/composition of shrub and herbaceous species and photographic evidence will be reported for information purposes. ' 1.5 STREAM 1.5.1 Initial Monitoring Plan ' Monitoring and success criteria will be established through periodic measurement of stream stage and rainfall in the Bank. One staff gauge will be placed on central sections of the mitigation stream reach and the second staff gauge will be located approximately 300 feet below outfall from the Bank. ' Rain gauges will be placed at open locations within central portions of the Bank. Stream stage and rainfall will be measured weekly throughout the monitoring period. I 1.5.2 Updated Monitoring Plan Stream monitoring and success criteria will be established through measurement of in-stream flows, measurement of stream geometry, and measurement of biological stream attributes. In-stream flows will be measured through placement of two continuos monitoring stream flow gauges. The gauges will be capable of recording velocity (ft/second) and discharge (cubic feet per second. CFS). Discharge is typically calculated by measuring height (or depth) of the water column and inputting the resulting cross-section. One gauge will be placed within the central reach of the restored stream channel on the mitigation site. The gauge will be located approximately 100 feet downstream of a former dirt road crossing in central portions of the site (Drainage Area: 2.5 mi':). The second gauge will be placed within the riverine wetland reference site in Bladen Lakes State Forest. The reference gauge will be located a minimum of 100 feet upstream of the State road Pale 3 of crossing (Drainage Area: 6.7 mi'). The data will be reported as mean daily flows for velocity (ft/second) and discharge (CFS) in tabular and graphic format. C I I Stream geometry will be measured along a fixed stream reach located immediately upstream and/or downstream of the stream gauge located on the mitigation site. The stream reach will extend for a minimum of 200 feet along the restored channel. Annual fall monitoring will. include development of a channel plan view, three channel cross-sections, pebble counts, and a water surface profile of the channel. The data will be presented in graphic and tabular format as summarized in the attached table. Data to be presented will include: 1) cross-sectional area; 2) bankfull width; 3) average depth; 4) average width; 5) width/depth ratio; 6) meander wavelength; 7) beltwidth; 8) water surface slope: 9) sinuosity; and 10) stream substrate composition. The stream will subsequently be classified according to stream geometry and substrate (Rosgen 1996). Significant changes in channel morphology will be tracked and reported by comparing data between the reference stream and mitigation stream and by comparing data in each successive monitoring year. Biological stream attributes will be measured annually at the mitigation site and in the reference wetland site between April 15 and May 15 of each year. yAquatic surveys will record presence/absence of macro-invertebrate, reptile, amphibian, and fish species populations. Presence/absence of species populations identified will be reported along with observations of changes to in-stream aquatic habitat or species presence/absence over time. 1.6 STREAM SUCCESS CRITERIA 1.6.1 Initial Monitoring Plan Success criteria will include establishment of near-permanent stream flows within the Bank. Specifically, stream stage and observable flow must be present for a minimum of 80% of the calendar year. Intermittent flow may occur during periods of groundwater draw-down, generally confined to summer months. y 1.6.2 Updated Monitoring Plan Success criteria for stream restoration will include: 1) stream classification; 2) target mean daily stream flows; and 3) increased stream faunal recruitment and diversity. Stream geometry measurements will be incorporated into the Rosgen stream classification system. ' The channel and flood prone area must support characteristics supporting an E. C, or DA stream type to fulfill the success criteria. In-stream flow measurements must indicate that the mitigation stream reach supports mean daily flows per unit of drainage area equal to. or exceeding the mean daily flows per unit of drainage area within the riverine reference reach. The reference stream reach supports an approximate 6.7 mi' drainage area while the mitigation stream reach supports an approximate 2.5 mi'- drainage area (37'0 of reference). Therefore, mean daily flows in the mitigation reach must equal to, or exceed 3070 of the mean daily flows in reference. If the mitigation reach and/or reference reach support no Pale 4 of 1 measurable flow during a drought period, fulfillment of success criteria will be based upon mean daily flows prior to, and following the no flow condition. i Biological monitoring will indicate similar species diversity as compared to reference conditions or an increase in species diversity towards reference conditions over time. Specifically, the type and ' number of species populations. identified in the mitigation reach must be equal to, or increasing towards, the type and number of species identified' dentified in the reference reach in each successive monitoring year. 1.7 REPORT SUBMITTAL Documentation will be submitted to the MBRT certifying completion of implementation activities. ' Any changes to this mitigation plan will be described in this documentation. The document will be provided within 60 days of completion of all work at the Site. ' Subsequently, reports will be submitted yearly to the MBRT following each assessment. Reports will document the sample transect locations, along with photographs which illustrate site conditions. ' Surficial well data will be presented in tabular/graphic format. The duration of wetland hydrology during the Growing season will be calculated at each well. within each on-site physiographic area. and within the reference wetland site. The survival and density of planted tree stock will be reported. In addition, characteristic tree ' species mean density and average height as formatted in the Vegetation Success Criteria will be calculated. Estimates and photographic evidence of the relative percent cover of understory and groundcover species will be generated. 1.3 CONTINGENCY In the event that vegetation or hydrology success criteria are not fulfilled, a mechanism for ' contingency will be implemented. For vegetation contingency, replanting and extended monitoring periods will be implemented if community restoration does not fulfill minimum species density and distribution requirements. ' Hydrological contingency will require consultation with hydrologists and regulatory agencies if wetland hydrology restoration is not achieved during the monitoring period. Recommendations for ' contingency to establish wetland hydrology will be implemented and monitored until the Hydrology Success Criteria are achieved. Performance bonds have been established to guarantee fiscal resources for remediation. ' Page 5 of 5 C I I H I I r I APPENDIX E. Supplemental Actions Taken at Barra Farms 1999-2000 I C C I k r I SUPPLEMENTAL ACTIONS TAKEN AT BARRA FARMS CAPE FEAR REGIONAL MITIGATION BANK 1999-2000 The following is a list of actions that have been or will be taken to improve the quality of monitoring and insure future mitigation success at Barra Farms: 1. Installation of six 18" diameter drainage pipes along the north section of Barra to alleviate ponding. The pipes were installed in October of 1999 to reduce the standing water created by rainfall from hurricanes and from any future heavy rain events. Ponded water will be lowered only during and/or after extreme climatic rainfall events after which ponding could be detrimental to the growth of survival of character species. The pipes will not allow groundwater levels to recede below the wetland hydrology thresholds and can be plugged in dry periods to allow percolation into the wetland before standing water is released. 2. In January of 2000, the mouth of the mitigation stream at Barra was cleaned of debris such as fallen limbs and snags to increase stream flow and further reduce standing water in this area. 3. The percentage of Barra being sampled for vegetation was increased in Year 2 monitoring. In Year 1 monitoring, 24 plots, each 0.05 acre in size, were sampled resulting in a total of 1.2 acres surveyed. In order to get a larger sample of representative vegetation and to pinpoint the location of areas not meeting the vegetative success criteria, the sampling area was increased in 1999. In Year 2 monitoring, 34 plots that were each 0.1 acre in size were sampled resulting in 3.4 total acres surveyed. This is a 283% increase in sampling size between Year 1 and Year 2. These 34 plots include 19 of the original 24 plots plus an additional 15 plots randomly placed in areas generally lacking plots. 4. In December of 1999, a subcontractor hired by ECOBANK installed 3 new RDS monitoring wells at Barra to get a more precise and continuous account of hydrology. A total of five RDS wells now read hydrology data on-site and 2 RDS wells are located at reference sites. 5. Supplemental planting was completed on February 11, 2000. Species that have thus far shown an ability to survive at Barra were planted across the groundwater flats and headwater slope habitats, which comprise approximately 362 acres at this site (Table 1). C Table Number and species of trees planted at Barra Farms during the winter of 2000. Common Name Scientific Name Number Ordered Atlantic White Cedar Chamaecyparis thyoides 4000 Bald Cypress Taxodium distichum 6000 Black Gum Nyssa sylvatica 1000 Eastern Sycamore Platanus occidentalis 800 Green Ash Fraxinus pennsylvanica 2500 Pond Pine Pinus serotina 2000 Swamp Blackgum Nyssa Mora 6500 Sweetgum Liquidambar styraciflua 2000 Water Oak Quercus nigra 6000 Water Tupelo Nyssa aquatica 5600 Willow Oak Quercus phellos 5900 Yellow Poplar Liriodendron tulipifera 1000 TOTAL 43,300 ' These species were evenly distributed across the former crop land at Barra (Figure 1). However, in wetter areas, such as the headwater slope habitat, a greater number of bald ' cypress and water tupelo were planted, since these species are better adapted to wet conditions. We also planted a greater variety of species in areas presently lacking diversity ' in order to meet mitigation requirements. Planting actions were closely monitored by Land Management Group, Inc. personnel. A total of 43,300 seedlings planted across 362 acres resulted in approximately 120 trees/acre. Since an average of 241 characteristic trees/ac ' (average of groundwater flats and headwater slope habitats) were observed in Year 2 monitoring, this supplemental planting increased tree density to 361 trees/acre. These trees, in addition to new volunteers and the established trees already present, will help ' Barra achieve the vegetative success criterion of 320 characteristic trees/acre over the required monitoring period. ' 6. Since the continuous monitoring stream gauges placed in the reference and restoration streams in 1999 have been somewhat unreliable, staff gauges will be replaced and used as a backup measure of stream flow. The staff gauges will insure continuous collection of ' flow data and will allow a more accurate assessment of stream mitigation. 11 PG o ? .? o ? o •? si cq b w N ON 00 C> u" ZC I I r 4. c d0 J to L sn. a? • o y N ?

Flanagan Research Associate Greg Bruland, Matt Hanchey Graduate Students And Dr. Curtis J. Richardson Director Duke University Wetland Center May 5,2000 The Duke Wetland Center is currently performing research at the Barra Farms Cape Fear Regional Mitigation Bank with the objective of improving water quality in the Harrison Creek watershed and ultimately in the Cape Fear River. The United State Department of Agriculture (USDA) sponsors this three-year research program. At the watershed scale, the importance of wetlands to the maintenance of biodiversity, water quality, and natural hydrologic regimes depends at least in part on the total wetland area, types and spatial arrangement. The North Carolina Wetland Restoration Program (NCWRP) was mandated to develop basin-wide wetland restoration plans primarily to improve water quality. The primary objective of our study is to develop a procedure for configuring mosaics of restored wetlands to yield the greatest positive cumulative effect on watershed-level water quality given a set of ecological, economic and political constraints. This study centers on the development of a Decision Support System (DSS) to assist NCWRP in siting restored wetlands to maximize watershed-level water quality improvement. The DSS will rely upon an economic model of land use and farmer willingness to participate in restoration programs, and a multivariate regression model of flow-weighted water quality parameters verses watershed variables including the area, type, shape and location of wetlands. A non-point source water quality model is being developed and calibrated using data collected from the NAWQA indicator watersheds and will be validated using field data collected from the Barra Farms site. The water quality model will be coupled with an economic model of landowner decisions to participate in the NCWRP as a function of their socioeconomic characteristics, various aspects of the program and other factors that affect land use decisions. An economic analysis of the individual restoration project will also be conducted to test the results of our conceptual model, and the effectiveness of the NCWRP from the landowner's point of view. To date, both field and simulated water quality data indicate the Barra Farms project is having a positive effect on water quality. Figures 1 and 2 show total phosphorus and nitrogen concentrations in storm runoff from the restored wetlands and adjacent agricultural lands at the site. These figures indicate the restored wetland is having a substantial positive impact on the water quality of Harrison Creek, and consequently on the Cape Fear River. Figures 3 shows simulated water quality in the upper portion of Harrison creek with and without wetland restoration. The model indicates wetland restoration on agricultural lands substantially reduces s r particulate bound phosphorus at the watershed scale. These results agree with observed water quality improvements at Barra Farms in the restored wetland areas. Early results of this study indicate that the Barra Farms Cape Fear Regional Mitigation Bank is providing improved water quality functions. We anticipate data gathered from this site will assist state agencies, such as NCWRP in demonstrating improved watershed water quality resulting from wetland restoration. The next phases of this research will result in complete water budget as well as a regional model that can be used to predict water quality improvements in the Cape Fear Watershed as well as measurements of other ecological functions on both restored and natural wetlands in the watershed. The cooperative work and exchange of data with the restoration program at Barra Farms is essential to the completion of this project. UTP in outflow from Rest. Wetland & Ag.

I,& 19 1 Reference the Year 1 Wetland Monitoring Report we received on December 16, 1998. Also reference the individual vegetation plot data that were provided to the MBRT on May 5, 1999 during an inspection of the Bank property. Also present during the May 5 meeting were. Mr. Bill Hoebeck of ECOBANK, Inc and Mr. Jerry McCrain of EcoScience, Inc. As you are aware, concern has been expressed about how the monitoring report was prepared, especially as it relates to data on the survival and recruitment of target tree species. I have solicited written comments from other members of the MBRT that are enclosed for your review. Based on the monitoring report, we feel that the sampling protocol does not adequately characterize densities and distribution of desirable tree species over the entire site. We realize that the MBRT agreed to the number and size of sample plots early in the planning phase for this project and this correspondence does not change that commitment. However, averaging the data over 19 random sample plots to arrive at a single stem density for the entire restoration area is inappropriate as this method of reporting data does not provide any information relative to the distribution of tree survival across the site. We note that only 0.2% of the restoration area is being sampled. Based on the data, many of the plots contain only one or two target species, and at densities considerably less than 320 stems/acre. Overall, only 11 plots (19 total in the reforestation area) contained more than 320 characteristic trees/acre. In addition, we have noted that only one plot (#12) contains greater than five species. Most of the plots (16 of 19) contain three or less species. As we discussed and noted during our May 5 visit, large areas in the former fields appeared to be devoid of saplings. For example, plot P6 apparently contains no surviving seedlings, while plot P6B only contains 220 stems/acre. This indicates that this area contains significantly fewer species than what is required by the success criteria. If this is truly indicative of stem densities on this portion of the tract, then supplemental planting is warranted. In addition, it appears that black willow densities exceed the allowable 10% of the 320 stem/acre requirement Finally, our Compensatory Hardwood Mitigation Guidelines specifically state that plot data must be representative of the entire site or communities of the entire site. This is to preclude instances where a particular section of a site is developing satisfactorily while other sections remain devoid of vegetation. In this case, we would insist, at the very least, that plot data only be averaged for the different physiographic landscape units. As the plot data seems to indicate a large degree of variability across the site, we suggest that you consider enlarging the sample plots to one acre. This may resolve some of the issues regarding stem densities. Based on our assessment of the plot data and our site inspection we feel that supplemental planting is warranted. We will be happy to discuss this remedial action including specific areas to re-plant at your convenience. - During the May 5 meeting, the MBRT also inspected the ditch and berm that bisects the headwater tributary to Harrisons Creek. Although the ditch has been plugged and portions of the berm have been removed, the former field on the north side of the ditch and berm contained a significant amount of standing water that appears to have led to high mortality of seedlings in this area. We would suggest that you explore options to release this water to the tributary or at least determine why this area contains this much ponded water. We would expect that prior to agricultural conversion that this area would have drained to the tributary. The MBRT also made a cursory inspection of an approximately 50 acre ponded area on the northeast portion of the restoration area. We agree with the NC Division of Water Quality. (DWQ) and Mr. Kevin Moody of the US Fish and Wildlife Service that while this is not.inherently detrimental to the site, it is not consistent with the mitigation plan. Accordingly, we suggest that the size of this area be more accurately determined and the duration of flooding that occurs under normal circumstances be determined. If this assessment indicates that the duration of flooding will lead to the creation of permanent, open-water emergent marsh habitat, then measures should be taken to reduce the size of this area. We agree with DWQ that a target area of 20 acres may be appropriate. We were also made aware that the RDS wells were programmed incorrectly and that this data was not available for the first year monitoring report. We trust that this problem has been corrected and that this data will appear in the next monitoring report. Finally, we feel that it would be premature to release any more credits from this bank until these issues have been resolved to the satisfaction of the MBRT. 2 We appreciate the opportunity to comment on this project.

D E N R October 27, 1999 Re: Remedial Actions and Supplemental Planting Plan, Barra Farm Mitigation Bank Action ID No. 199704890 Dear Mr. McLendon, This letter is a response to the Remedial Actions and Supplemental Planting Plan submitted by Barra Farms Mitigation Bank for the Year 1 Monitoring Report. The Remedial Plan calls for three major actions: 1. installation of 6 18-inch flashboard risers to control ponding, 2. supplemental planting of approximately 15,000 trees on 36.1 acres as identified on Chart " A", and 3. the addition of supplemental monitoring plots. Urnu ` 9 The Division of Water Quality is concerned with the installati (nof the 6 flashboard risers. The Division understands the need to alleviate the pon on the 40 acre affected area, however, it would seem that a remedial measurvert' the water toward the headwater area. In addition, for the risers to work, a ditch must have been constructed to facilitate drainage away from the designated areas. No mention was made as to the placement or extent of these ditches. Moreover, does not the placement of water control structures on-site alter the site's designed hydrology? The Division of Water Quality approves of the supplemental planting areas as shown on Chart A. However, concerning Table 2 and the species to be planted, the Division feels strongly that there is no need to plant Acer rubrum. The Remedial Action Plan also calls for the addition of supplemental monitoring plots as recommended by the Mitigation Bank Review Team (MBRT). The Division approves of adding more monitoring plots, however, the Division feels that the amount of area monitored should at least be 2 to 3 percent of the site. The current plan calls for increasing the sample area from 1.2 acres to 3.9 acres. The plot size change translates to increasing the sample size from .19 percent of the site to .63 percent of the site. The ' MBRT previously recommended sampling at least 2 to 3 percent of the site. The Division feels that increasing the plot size to .25 acre would be sufficient. P.O.

As you may recall, the MBRT met with the Bank sponsor on May 5, 1999 to discuss issues relative to: +/- 50 acre ponded area in restoration area. number and size of sample plots tree mortality After several discussions with the sponsor, they have agreed to provide a remedial action plan that will detail (1), continued monitoring of the ponded area, (2), a revised vegetation sampling plan that will provide sufficient data to determine if stem density requirements are being met, and, (3), and a specific plan to replant those areas at the bank where plot data indicated stem densities were less than 320 trees/acre. This remedial planting will ocurr in the winter of 1999/2000. The bank sponsor is soliciting the MBRT's input as to where the remedial planting should occur. Provided this plan meets with our and your approval, we will release the year 1 credits (24 credits) immediately. It is expected that an inspection of the site will be made in April/May of 2000. If this inspection indicates that remedial planting is successful, then year two credits would be released. I will forward this plan to you when I recieve it. Your quick response would be appreciated.

McClendon, Regulatory Specialist Regulatory Division U.S. Army Corps of Engineers P.O. Box 1890 Wilmington, NC 28402-1890 Submitted by: ECOBANK New Bern, NC Winter Park, FL October 8, 1999 OCT.13'1999 08:51 9102514025 introduction: USAED WILMINGTON #0470 P.004 During the September 28, 1999 meeting with the USACOE, (Messrs. Ernie Jahnke, David Franklin and Scott McLendon), we committed to submitting this Supplemental Planting Plan to remediate percelved mortality of target species identified in the first year monitoring report. As you recall, the year one quantitative sampling of the vegetation occurred in mid-October 1998 with the examination of 24 permanent plots. Each plot is circular representing .05 acre and is located near a permanent shallow hydrology monitoring well. It was agreed that the project meets or exceeds the Section 404 wetland hydrology parameters in year 1. This plan is therefore submitted to identify potential deficient plant stock areas based on the year 1 report and subsequent MBRT review comments, as well as to correct these deficiencies to your stated requirements Review of Our Plan's Success Criteria our goal is to restore this farmland tract back into a functional wetland with strong evidence during the 5 year monitoring period that this goal is attainable to the MBRT's satisfaction. We believe that once the hydrology is monitored and closely resembles adjacent, natural control sites, then the vegetation will follow through natural recruitment. Those hydrophytic plants that were chosen to be planted and survive will be naturally selected to withstand future environmental and climatic rigors of the site. Over time, extreme events such as flooding will be more buffered by the accumulation of a thick Al horizon (leaf litter) soil profile which will consist of naturally selected and appropriate wetland plant species, rootstock and mast. We committed in the approved mitigation plan to jump starting this natural recruitment, process by planting 435 stems/acre of approximately 12 different species of wetland overstory trees. The success criteria stated that over the five year period we would achieve a mean density of 320 characteristic (planted and volunteered) treestacre of which at least 5 character tree species (those planted) must be present. Also, no more than 20% (64 stems) of the 320 stems/acre can be comprised of any one planted species. No more than 10% of the 320 stemstacre requirement may be softwood species (black willow, pond pine, loblolly pine, etc.). Surface Pondin Remedial Actions The comments from the MBRT are acknowledged regarding locations where plants seem to be absent. We strongly believe climatic factors from the wettest (El Nino) Winter/Spring in recorded history, which occurred in the first 7 weeks of our planting .effort, caused most of the perceived seedling mortality. We have initiated a remedial plan to lower these unusual climatic rainfall ponding events through the installation of six 18" flashboard risers through the northern farm roadiberm. Pondin water wit lowered only durin andfor after extreme climatic rainfall events after w ich ondirtl cool be a rimental ?totne rowth or survival o atir 12 character q3erlias, This lowering activity w e c ose itored on a periodic basis after flashboard risers are removed. In no event will the risers allow groundwater levels to recede below the wetlanI hydrology thresholds. Risers have been designed only to lower ponding. Conversely, the risers can be elevated in a dry period to allow percolation into the wetland before standing water is released. It is anticipated that, upon completion of the 5 year monitoring study, the optimum riser height will be achieved to maintain a better permeability/surface flow equilibrium. ??h r4 2 OCT.13'1999 08:52 9102514025 USAED WILMINGTON Mon on of Poten ial Emer n Marsh Wetland #0470 P.005 As noted in the various comments, it may be inherently desirable to have a fresh water marsh component in the bank. While not originally planned, If this habitat type becomes a desirable feature, we will monitor future successional characteristics and project the longevity of its existence during monitoring years 3 and 4. The rapid stabilization of 35- 40 acres with dense emergent obligate plants and associated fauna can be a plus to habitat conditions and water storage. This zone is illustrated on Chart "A" and may be, found to be more desirable than the original planting goal. We have found this area to be comprised of a tighter, very low permeability black clay which sits in a slightly (+/- 1.51) lower landscape position. We propose to Install 94 continuous recording device for daily readings in the center of this impoundment. In this manner, we can match drawdown rates with manipulation of the flashboard risers to maintain quality emergent marsh and scattered bald cypress/tupelo habitat. ldentlfled Areas for RQOlantinsr Based on the first year monitoring report, three open field zones appear to have the highest seed mortality. As was identified in the MBRT comment letters, the sparsest seedling survival areas were found in and around P6, P8, and P24-A & 8, These areas total 36.1 acres as illustrated on Chart "A".. Individual acreage breakdowns are shown in Table #1. Other noted areas, including P14, P18, P21, and P23, are found within very dense existing pocosin type natural foliage. Identifying the small seedlings within this denso vegetation is difficult. Tally of seedling numbers should wait another growing season to better define their survival status. We believe that a greater replanting effort should be made within the open field zones. Tree Totals to be Plan d Since 435 stems/acre is our goal, we propose to completely replant those identified poor survival areas. We propose to plant up to 95,691 bare root seedlings of 10 character hydrophytic species as identified in Table #2. The original planting guide, with the same proportion of selected plants as noted, will be followed In these identified zones. Should the second year monitoring identify a deficiency of certain species, then target species may need to be readjusted to more closely match endemic soil/hydrology conditions. Of course, further remedial adjustments in planting composition will be presented to the MBRT for their review and concurrence. Additional Monitoring Plots we propose to maintain our existing monitoring database at the existing 24 plots and to increase the sampling area from .05 acre plot to a 0.1 acre plot. In addition, we propose to increase the number of vegetative sample plots to 39, which adds 15 plots across the tract. This will increase the sample area from 1.2 acres in year 1 to 3.9 acres sampled for year 2, which is a 325% increase In sampling information. -1 3 OCT.13'1999 08:52 9102514025 USAED WILMINGTON #0470 P.006 Cred Release The supplemental planting will occur during the 1999 dormant season (November, 1999 - January. 2000). The surface ponding remedial activities are underway and will be completed before the end of October, 1999. It was agreed at the September 28 meeting that the 1998 credits (24) will be released upon satisfactory submission of this plan. In addition to the year 1 and year 2 monitoring report, It has been agreed that ECOBANK will undertake a mid-year (year 2.5) report at first growth (early Spring, 2000) followed by a combined site visit (ECOBANK and MBRT) to evaluate the supplemental planting regime and accommodate the deviations caused by the time lag and seasonal differences of disparate readings by ECOBANK and the MBRT_ This procedure will achieve equitable release of the 1999 credits (36) on the date of review- Conclusions We are committed to ensure that Barra Farm becomes a viable self-sustaining functional wetland system. We will demonstrate this commitment by monitoring the ponded zones; Installing flashboard risers to manage extreme rainfall events; replanting 36.1 acres to specification during the coming dormant season and Increasing this year's (October 1999) sample area threefold. Since we are dealing with many unknowns, which Mother Nature so wondrously exhibits, we acknowledge that mitigation plans need occasional adjustments. We strongly urge that, at the completion of the year 2 monitoring period, the representatives of the MBkT field team review the documents in a timely fashion so wa, can adjust and address potential planting deficiencies quickly. We appreciate your speedy review of this remedial plan. Your constant surveillance of our progress is appreciated and helpful. We look forward to working with you to the successful completion of this project. 4 OCT.13'1999 08:52 9102514025 USAED WILMINGTON 00470 P.007 Table 1.
