PO Box 2522 Wilmington, NC 28402 Dear Ms. Williams. 01?WAA "ft NOOK NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES December 7, 2000 The NC Division of Water Quality (DWQ) has received a copy of the second year monitoring report for Winding River Plantation. The report offers much information in order to consider the project as a success. However, staff from the NC Wetlands/401 Unit have not seen the site, and a site visit will be necessary in order to consider the success of the project. We believe that a site visit should occur next summer at a time when the plants have achieved the greatest cover for the year. I would like to request that a brief description of the project be provided in all monitoring reports. Often staff members are not familiar with a project. These reports are often reviewed by staff outside the Wetlands/401 Unit that do not have a copy of the project file. Basic information would include the amount of impacts (e.g. acres impacted) and required compensatory mitigation. The summary of the required compensatory mitigation should include the type of mitigation (creation, restoration, enhancement or preservation) and the acres of successful mitigation required for each type. The quantitative data you provided on species density and indicator status are beneficial for review purposes. However, the methods used to obtain the data are not discussed in your report. Quantitative data on herbaceous species are obtained through the identification of all species present in sample plots. These plots may range in size but for herbaceous species are almost never larger than 1m2. The number, size and placement of plots sampled should be provided in all reports. How the plots are placed (randomly located?) and the date of sampling are other necessary items. Other reviewers noted that the slopes of the pond shelves, water depths associated with the shelves, a description of any water level fluctuations, the definition of "stem" would have been beneficial. The lack of an appropriate reference wetland was also noted.

In Table 2 of your report you list the number of stems for come clonal species (i.e. Juncus effusus), but it is not clear whether you are presenting data for the number of stems, or the number of clones. It is my experience to find hundreds of stems in one mature clone of Juncus effusus. In the scientific literature plant cover is estimated much more often than density for herbaceous species. The photographic documentation you presented in excellent, and I strongly urge you to continue using photographs in all of your reports. I believe the most prudent approach to evaluating this project will be to discuss the technical details during a site visit next summer. At that time we can determine the progress made to date, and whether any additional monitoring will be required.

Date Rec'd NCWRP: 12/6/00 Location: Winding River Plantation on Zion Hill Road in Brunswick County, North Carolina Impacts: 1.59 acres of wetland during golf course construction Proposed mitigation: A combination of 4.2 acres of enhancement and creation (reference wetland not defined) Actual mitigation: 2nd Year Monitoring Report claims to have enhanced 2.45 acres and created 4.29 acres of littoral shelves on golf course ponds. Other comments: • Thmte does not appear to be a targeted reference wetland available to compare to ci=liated wetlands. Mitigation ratios are not understandable in this report The following information should be included about the created and enhanced pond shelves: ? The slopes of the pond shelves ? The depths of water associated with the shelves ? Descriptions of water fluctuations in the ponds (Does the golf course use these ponds for watering their fairways?

Since the measure of stems per acre appears to be the sole criterion of successful creation or enhancement, this needs to be explained further in the text. Plan reviewed by: Jason Guidry and Mac Haupt Introduction In February of 1997, a mitigation plan that created 4.2 acres of on-site wetlands was developed to compensate for unavoidable impacts to 1.59 acres of wetlands occurring at Winding River Plantation. The site is located along Zion Hill Rd. in Brunswick County, North Carolina (Figures 1 & 2). The Winding River Mitigation Plan outlined the construction of littoral shelves with 40 foot intervals around 7 lakes associated with the Carolina National Golf Course and residential subdivisions, which created 4.02 acres of wetlands (Figure 3). Another 0.18 acre was created by expanding a wetland ecosystem next to hole 17. For these sites, the maintenance crew at the golf course planted a variety of nursery seedlings as well as local plants that were displaced from excavated areas. The original mitigation plan described vegetation success as the survival of 70% of planted wetland vegetation. However, records of exactly which species and how many individuals were planted are incomplete and an accurate account of the survivability of the planted vegetation is difficulf to determine. Therefore, the indicator status and density of plants now growing in created areas are evaluated in order to assess wetland establishment. Year 1 monitoring found four of the original eight mitigation sites to be unsuccessful in establishing wetland vegetation. However; eight other creation or enhancement areas within the golf course but not included in the mitigation plan compensated for these unsuccessful areas (Figure 3). A site was determined to be enhanced if it was previously delineated as a wetland, but received additional planting of wetland vegetation by the golf course. In total, it was determined that Winding River Plantation successfully created 4.29 acres of wetlands and enhanced 2.45 acres of wetlands on its golf course to mitigate for 1.59 acres of impacts, which actually exceeded numbers set in the mitigation plan. Therefore, mitigation after Year 1 was determined to be successful. All areas evaluated in the Year 1 monitoring report were examined again in this Year 2 report to fulfill mitigation requirements and to ensure that wetlands have permanently established. Hydrology No monitoring wells were installed at Winding River Plantation since most of the created areas were formed on the edges of ponds. Vegetation The original mitigation plan measured vegetation success based on 70% survival of planted wetland vegetation. However, the golf course did not keep a record of what species or how many stems were planted at these sites. Assuming vegetation was planted on a 24" spacing, 10,890 stems/acre would have been planted. Seventy percent survival is approximately 7,623 stems/acre. For this monitoring report, vegetation establishment was determined to be successful if at least 50% of the dominant vegetation had a wetland indicator status of FAC+ or wetter and the density of these wetland species was at least 1.88 stems/m2 (4046.5 m2 in 1 acre; 7623 stems/ac _ 4046.5 i0ac = 1.88 stems/m ). Year 1 monitoring found that of the 8 created areas, 4 areas totaling 1.77 acres (#5, 6, 7, and 8) did not meet success criteria. However, wetlands were successfully created or enhanced at the remaining sites (areas # 1, 2, 3, and 4) and at an additional 8 sites because planted vegetation and volunteer species with an indicator status of FAC+ or wetter made up a majority of the vegetation and wetland vegetation was well established. Year 2 monitoring found similar results as Year 1. Once again, creation areas #5-8 did not meet the success criteria (Figures 4 and 5, Table 1) because wetland vegetation failed to establish around the edges of these ponds in abundance. These sites were not counted towards mitigation success values. Wetlands were again found to be well established within creation areas #14 and all other additional sites reviewed in Year 1 monitoring based on vegetation and density (Figures 6-15, Table 2). Year 2 monitoring found a total of 4.29 acres of created wetlands and 2.45 acres of enhanced wetlands on site. 2 Summary For the past two monitoring seasons, Winding River Plantation has successfully created 4.29 acres of wetlands and has enhanced an additional 2.45 acres of wetlands on its golf course. In addition, the maintenance crew is continually planting wetland vegetation to beautify the golf course. This exceeds Winding River Plantation's original goal of creating 4.2 acres, which was proposed in its mitigation plan. Because wetland mitigation has been monitored and determined successful for two consecutive years, as was required by the Winding River Mitigation Plan, this is the final monitoring report. ?4 Table 1.

The applicant proposes to impact wetlands associated with the development of the road system for the Winding River Plantation and the associated Carolina National Golf Course. The site is located along Zion Hill Road in Brunswick County, North Carolina with the northernmost boundary being located at the intersection of Zion Hill Road and Leaning Pine Road (Figure 1). The proposed mitigation will include 4.2 acres of on-site created wetlands. The created wetlands will be formed as littoral shelves around created lakes at ratios consistent with Division of Water Quality (D.W.Q.) policy. The created wetlands will be monitored for a two year period. MINIMIZATION Both the overall site plan and golf course plan have been design with wetland 1 minimization as a very high priority. The entire tract is composed of approximately 1100 acres and contains approximately 400 acres of wetlands. The applicant has been able to design the project with minimal wetland impacts. Residential lots have been designed to require no wetland fill. The proposed site plan impacts approximately 0.4% of the on site wetlands. Approximately 80% of these impacts are associated with road crossings necessary to provide upland access and to complete roads to NC 0 - Y ` C t3lt>? .

Therefore, the applicant believes that the proposed impacts will have minimal impacts to the surrounding environment. IMPACT ASSESSMENT The impacted wetlands consist of small, isolated depressional wetlands, and riverine wetland fingers associated with the Sandy Branch wetland ecosystem. All riverine fingers are located above headwaters (Figure 2), and therefore eligible for Nationwide 26 permits. Data sheets for the depressional and riverine wetlands are shown in Appendix A. Typical riverine wetlands (Figure 3) are dominated by Fraxinus pennsylvanica, Liquidambar styraciflua, Acer rubrum, and Quercus nigra in the overstory; Lyonea lucida and Ilex coreacea in the shrub layer; Vitus rotundifolia as a woody vine, and Lyonea lucida in the herb layer. Muckalee is the typical soil series. The depressional wetlands (Figure 4) are dominated by Nyssa aquatica and Gordonia lasianthus in the overstory; Magnolia virginiana in the shrub layer, Osmunda cinamonea in the herb layer; and Vitus rotundifolia as a woody vine. The depressions are located in patches of Baymeade and Marvyn soils. IMPACT AREAS Nationwide 14 Areas Nationwide 14 permits are needed for a total of 0.5474 acres. This total includes four crossings of less than 200' centerline length (Figure 5). The first crossing (NWP 14 #1) consists of a crossing of approximately 50' centerline length and 0.0871 acres. 1 I e Figure 2. U.S.G.S. 5 CFS Maps i 0 Figure 3. Typical riverine wetland.

LAND MANAGEMENT GROUP, INC February 4, 1997 Winding River Plantation Brunswick County, NC 10 This area crosses an unnamed tributary of Sandy Branch. The crossing is necessary to maintain access to the northeastern section of the tract and yet utilize an existing entrance. The second crossing (NWP 14 #2) (Figure 5) consists of an approximately 30' centerline length crossing (0.0652) which crosses another unnamed tributary of Sandy Creek. The land plan has minimized this crossing by crossing at point of minimal distance. Crossing # 3 (Nationwide Permit 14 #3) is approximately 100' centerline length and contains 0.1494 acres. This crossing has been designed to minimize crossing distance while providing upland access. Crossing # 4 (NWP 14 # 4) has a -100' centerline length and totals 0.2457 acres. This crossing was designed to provide upland access while minimizing crossing distances. Nationwide 26 Areas A NWP 26 permit is needed for eleven areas totaling approximately 1.05 acres. All of these represent either hydrologically isolated wetlands or those that are located above headwaters. Of these totals, six areas (-.74 acres) are associated with road crossings and five fill areas (-0.31 acres) are needed for the completion of the Carolina National Golf Course. No lot fill is requested. 0 ?I A 5-1 •• Y .t t I h ?? rt •'. C4 1•t ,.:.•t 1• ? . , ,t ??? ???/ 1'r V `?::.: •:•? „mot Nit ? i.J:Y.

Fill is necessary to complete a -!90' centerline length crossing. The area is connected to NWP 14 #1 so a Nationwide 14 permit was not applied for. This crossing is necessary for upland access and has been previously cleared in error. The fill area has been minimized by using the upper edge of the finger thereby not separating the wetland area. The second Nationwide 26 area (NWP26 # 2; Figure 6) represents a crossing of an isolated wetland. Fill is necessary to complete a road crossing and totals 0.1281 acres. The crossing has been minimized by crossing the outside edge of the wetland. The third and fourth Nationwide 26 areas (NWP #3 and NWP # 4; Figure 6) represent 40' and 100' crossings totaling 0.1261 and 0.0727 acres respectively. These crossing are necessary for upland access and have been minimized by crossing at minimum wetland widths. The fifth Nationwide 26 crossing (NWP #5; Figure 6) will consist of creating a wider angle of repose to the crossing of Sandy Branch. This crossing (0.1290 acres) is necessary to bring the existing state road (Zion Hill Road) to NC Department of Transportation specifications. The crossing is greater than 200' centerline length, hence the NWP 26 application. The sixth requested area (NWP 26 # 6; Figure 6) consists of approximately 0.0217 acres. Fill of this area is necessary to complete an underground golf cart tunnel which is necessary to eliminate a safety hazard of golf carts crossing south of the 14 intersection of Zion Hill Road and Goley Hewett Road. Golf course nationwide 26 request Five fill areas (NWP 26 #s7-11; Figure 7) represent isolated wetland areas totaling approximately 0.31 acres. Fill of these areas is necessary to complete the 0 Carolina National Golf Course. Impacts have been minimized as much as possible. The vast majority of wetlands have been preserved and utilized in the golf course design for aesthetic purposes. MITIGATION RATIOS A total of 4.34 acres of wetlands will be created on-site to compensate for the unavoidable loss of 1.6 acres of wetlands for an average ratio of 2.56 acres created to 1 acre impacted. Mitigation ratios for each proposed fill area were determined using D.W.Q. standards and are summarized in Table 1. Mitigation will be accomplished through the creation of eight areas of littoral shelves around lakes created as part of the golf course and associated residential development. The remaining 0.68 acres will be created by expanding a wetland ecosystem. CREATION MITIGATION Littoral shelves will be created around six lakes associated with the Carolina 1 1 00 0 w O a a? U -.

VEGETATION Creation Areas 1,3,45,67, and 8 U Mitigation will be completed by planting emergent vegetation around the littoral shelves around the edges of the lakes. Pontedaria cordata, Saururus cernuus, Peltandra virginica, Juncus effusus, Saggitaria latifolia, Scirpus pungens, Scirpus validus, and Zizania aquatica will planted. These species were selected from a list provided by Mr. Steve Kroger of D.W. Q. A rate of 70% survival of planted and volunteer wetland species at the end of two years will be the mitigation success criterion. After initial plantings, no alteration of vegetation will occur on the littoral shelves. Creation Area #2 Mitigation on this area will be completed by planting Ilex glabra, Lyonea lucida and Ilex coreacea in the excavated area. As with the previous areas, a survival rate of 70% of planted and volunteer species at the end of two years will be the mitigation goal. MONITORING Vegetation establishment and success will be monitored for a two year period. A 24 1-1 0 Creation Area Figure 14. Creation area # 2. LAND MANAGEMENT GROUP, INC February 4, 1997 SCALE 1 " = 200' Bluegreen Corp. Winding River Plantation Brunswick County, NC 25 National Golf Course and residential subdivisions (Figures 8,9,10,11,12). These shelves will be constructed with 40' wide intervals as shown in Figure 13. A minimum of 70% success at the end of the second year will be the success goal. Due to the small area of the creation areas, each area will be examined and no sample plots will be needed. The creation areas will be examined bimonthly quarterly. Volunteer species will be considered acceptable if their stem densities do not exceed equal proportions of the chosen plants. A series of simple mitigation reports will be submitted to D.W.Q. within 30 days of the following target dates: 1. The completion of planting activities. 2. Six months after the completion of planting 3. On the bi-annual planting anniversary dates for the duration of the monitoring period. Each report will consist of a simple narrative explaining the monitoring results, mortality rates, remedial action taken, and problem resolution. Pictures of both successful and problem areas will be submitted. CONTINGENCY PLAN If the mitigation is determined to be successful, monitoring will be terminated at the end of two years. If deemed partially successful or unsuccessful, a contingency plan may be instituted. This plan will consist of additional plantings which may be necessary to achieve mitigation goals. 26 SUMMARY The applicant proposes to create approximately 4.3 acres of wetlands to compensate for the unavoidable loss of approximately 1.6 acres of wetlands caused by road crossings and golf course completion of the Winding River Plantation and Carolina National Golf Course. Mitigation ratios have been designed to D.W.Q. specifications. Special care has been taken to minimize the wetland impacts. The applicant feels that the proposed impacts represent minor wetland impacts that are more than adequately offset by the proposed mitigation.

Prepared for: Mr. John Dorney NC Division of Water Quality 4401 Reedy Creek Road Raleigh, NC 27607 Prepared by: Land Management Group, Inc. August 20, 1999 Job # 97-028 0?4 Introduction In February of 1997, a mitigation plan that created 4.2 acres of on-site wetlands was developed to compensate for unavoidable impacts to 1.59 acres of wetlands occurring at Winding River Plantation. The site is located along Zion Hill Rd. in Brunswick County, North Carolina (Figures 1 & 2). Littoral shelves with 40 foot intervals were created around 7 lakes associated with the Carolina National Golf Course and residential subdivisions to create 4.02 acres of wetlands. Another 0.18 acre was created by expanding a wetland ecosystem next to hole 17. For these 8 sites (Figure 3), the maintenance crew at the golf course (led by Dr. Terry Vassey) planted a variety of nursery seedlings as well as local plants that were displaced from excavated areas. Since planting at the golf course is consistently taking place, records of exactly which species and how many individuals were planted are incomplete and an accurate account of the survivability of the planted vegetation is hard to determine. Therefore, in order to assess wetland establishment the indicator status and number of plants now growing in created areas are evaluated. Hydrology No monitoring wells were installed at Winding River Plantation since most of the created areas were formed on the edges of ponds. Vegetation To evaluate vegetation at mitigation sites, an estimation of the number of stems for all dominant species was recorded. The density of each of these species was then calculated by dividing the number of stems by the area of the mitigation site (in ft2). Overall density of the dominant vegetation appears low for some sites because the size of the plants and other nondominant vegetation were not taken into account. Of the 8 created areas, ", because _70yoummil 1 ii ii 111 !I'll most planted vegetation did not survive and volunteer species are pa c y (Figures 4 & 5). This may have been a result of the slope of the littoral shelf being too steep or too flat. However, wetlands were successfully established at the remaining sites (areas # 1, 2, 3, and 4) because planted vegetation (Figures 6-9) and volunteer species with wet indicator statuses make up a majority of the vegetation (Table 1). Although only 2.5 acres of the 4.2 acres of created wetlands successfully established, Winding River Plantation has additionally lsewhere on the golf course (Tables 2 & 3), which more than makes up for the failed areas from the original mitigation plan. Most of these added mitigation sites have been vegetated for at least one year (Figures 10-16). Summary To date, Winding River Plantation has successfully and 10 111 has v ` In addition, the maintenance crew is continually planting wetland vegetation to beautify the golf course (Figure 17). This exceeds Winding River Plantation's original goal of simply creating 4.2 acres, which was proposed in its mitigation plan. LMG will continue to monitor the Winding River Plantation for at least two more years to ensure that wetlands have permanently established, especially in some of the newer mitigation areas.

Prepared for: Mr. John Dorney NCDENR Division of Water Quality Raleigh, NC 0 Prepared by: Land Management Group, Inc. Wilmington, NC November 7, 2000 Job # 97-028 Introduction In February of 1997, a mitigation plan that created 4.2 acres of on-site wetlands was developed to compensate for unavoidable impacts to 1.59 acres of wetlands occurring at Winding River Plantation. The site is located along Zion Hill Rd. in Brunswick County, North Carolina (Figures 1 & 2). The Winding River Mitigation Plan outlined the construction of littoral shelves with 40 foot intervals around 7 lakes associated with the Carolina National Golf Course and residential subdivisions, which created 4.02 acres of wetlands (Figure 3). Another 0.18 acre was created by expanding a wetland ecosystem next to hole 17. For these sites, the maintenance crew at the golf course planted a variety of nursery seedlings as well as local plants that were displaced from excavated areas. The original mitigation plan described vegetation success as the survival of 70% of planted wetland vegetation. However, records of exactly which species and how many individuals were planted are incomplete and an accurate account of the survivability of the planted vegetation is difficult to determine. Therefore, the indicator status and density of plants now growing in created areas are evaluated in order to assess wetland establishment. Year 1 monitoring found four of the original eight mitigation sites to be unsuccessful in establishing wetland vegetation. However, eight other creation or enhancement areas within the golf course but not included in the mitigation plan compensated for these unsuccessful areas (Figure 3). A site was determined to be enhanced if it was previously delineated as a wetland, but received additional planting of wetland vegetation by the golf course. In total, it was determined that Winding River Plantation successfully created 4.29 acres of wetlands and enhanced 2.45 acres of wetlands on its golf course to mitigate for 1.59 acres of impacts, which actually exceeded numbers set in the mitigation plan. Therefore, mitigation after Year 1 was determined to be successful. All areas evaluated in the Year I monitoring report were examined again in this Year 2 report to fulfill mitigation requirements and to ensure that wetlands have permanently established. Hydrology No monitoring wells were installed at Winding River Plantation since most of the created areas were formed on the edges of ponds. Vegetation The original mitigation plan measured vegetation success based on 70% survival of planted wetland vegetation. However, the golf course did not keep a record of what species or how many stems were planted at these sites. Assuming vegetation was planted on a 24" spacing, 10,890 stems/acre would have been planted. Seventy percent survival is approximately 7,623 stems/acre. For this monitoring report, vegetation establishment was determined to be successful if at least 50% of the dominant vegetation had a wetland indicator status of FAC+ or wetter and the density of these wetland species was at least 1.88 stems/mz (4046.5 m2 in 1 acre; 7623 stems/ac - 4046.5 i0ac = 1.88 stems/m2). Year 1 monitoring found that of the 8 created areas, 4 areas totaling 1.77 acres (#5, 6, 7, and 8) did not meet success criteria. However, wetlands were successfully created or enhanced at the remaining sites (areas # 1, 2, 3, and 4) and at an additional 8 sites because planted vegetation and volunteer species with an indicator status of FAC+ or wetter made up a majority of the vegetation and wetland vegetation was well established. Year 2 monitoring found similar results as Year 1. Once again, creation areas #5-8 did not meet the success criteria (Figures 4 and 5, Table 1) because wetland vegetation failed to establish around the edges of these ponds in abundance. These sites were not counted towards mitigation success values. Wetlands were again found to be well established within creation areas #1-4 and all other additional sites reviewed in Year 1 monitoring based on vegetation and density (Figures 6-15, Table 2). Year 2 monitoring found a total of 4.29 acres of created wetlands and 2.45 acres of enhanced wetlands on site. 2 Summary For the past two monitoring seasons, Winding River Plantation has successfully created 4.29 acres of wetlands and has enhanced an additional 2.45 acres of wetlands on its golf course. In addition, the maintenance crew is continually planting wetland vegetation to beautify the golf course. This exceeds Winding River Plantation's original goal of creating 4.2 acres, which was proposed in its mitigation plan. Because wetland mitigation has been monitored and determined successful for two consecutive years, as was required by the Winding River Mitigation Plan, this 0 is the final monitoring report. 0 3 Table l: Indicator status and density of vegetation found in unsuccessful mitigation areas at Winding River Plantation. # Size of Dominant Species Indicator Stems/ Total Creation/ Fig Area Status m2 stems/m2 Enhance No. ac (FAC+ or wetter) 5 0.55 Typha angustifolia OBL 1 1.5 C 4 Juncus canadensis OBL 0.5 6 0.55 Juncus canadensis OBL I C 4 Eupatorium capillifolium FACU 1 7 0.3 Juncus canadensis OBL 1 i C 5 Eupatorium capillifolium FACU I 8 0.3 Scirpus cyperinus FACW+ 0.5 0.5 C 5 Eupatorium capillifolium FACU 1 TOTAL 1.7 Table 2.
