We are providing copies of this document in accordance with Special Condition Z of the Department of the Army permit and the above referenced Water Quality Certification. A summary of vegetation and hydrology of the mitigation area is listed below. Vegetation. Based on sampling data the average number of living seedlings per acre for the Mayfaire mitigation site was 650 in October 2007, well above the success criterion of 260 trees per acre. Five species were present in the plots with bald cypress comprising more than 50 percent of the total. The fourth-year planted tree survival rate was 63 percent. 2151 Alternate Al A South • SUITE 2000 • JUPITER, FLORIDA 33477-3902 TEL 561/747-7455 • FAX 561/747-7576 • czrinc@czr-inc.com • www.CZRINC.com Ms. Jennifer Frye 8 April 2008 Page 2 Hydrology. Hydrology data from 2007 show that all well locations, or 100 percent of the restoration areas, met the greater than 12.5 percent hydrology criterion for wetlands during periods of normal or below normal rainfall. The 2007 annual report provides fourth-year monitoring information relative to the on-site restoration process that was initiated in early-2004 at Mayfaire. Vegetation has become established and is undergoing a progression of natural succession. Seedling density and survival meet permit/condition requirements, and hydrology of the site has also exceeded the minimum 12.5 percent criterion. Since the site has been monitored one year beyond permit conditions and the mitigation sites have become established with wetland characteristics, Mayfaire is requesting concurrence that mitigation monitoring may cease. Please contact us with any questions or if you wish to meet for an on-site evaluation.

The site is located west of Military Cutoff Road in northeastern New Hanover County. The on-site restoration is comprised of three areas: Area A, 0.19-acre adjacent to the unnamed tributary of Howe Creek in the southern portion of the site, Area B, 0.17-acre on the north side of Howe Creek, and Area C, 1.02 acres on both sides of Howe Creek near the western edge of the property (Figure 2). The on-site riparian restoration is intended to fulfill part of the compensatory wetlands mitigation for impacts to wetlands associated with the completion of Mayfaire in New Hanover County, North Carolina [see "Compensatory Wetlands Mitigation Plan" (CZR 2003) for details of the wetlands mitigation and monitoring plan]. Monitoring guidelines, success criteria, and requirements are further described in North Carolina Division of Water Quality's 401 Water Quality Certification (No. 3341-modified) and in the permit conditions issued by the U.S. Army Corps of Engineers (Action ID No. 20000135). The required on-site compensation is 0.74-acre, although the mitigation plan proposes restoration of 1.08 acres of wetlands. Collection of sub-meter- accurate GPS data points along the estimated restored wetland edge indicate that the acreage for the three areas totals approximately 1.38 acres, or 0.30-acre above the 1.08 acres proposed in the mitigation design. 1.1 Goal of the Proiect. The goal of this restoration project is to restore at least 1.08 acres of riparian buffer to forested riparian wetlands. The success of the restoration effort will be determined by the re-establishment of wetland hydroperiods and the presence of an acceptable density of trees at the end of the monitoring period. 1 0 3 6 SCALE IN MILES srtE: uTrtuoE LaNaTUOE 34'TS'00'N, 7T50'30'W 34'T3'S5'N, 7T50'301Y LOCATION MAP WETLANDS RESTORATION AREA MAYFAIRE MITIGATION MONITORING SCALE: AS SHOWN APPROV D BY: DRAWN BY: BFG DATE: $~~ 204 L,/ FILE: LOC-MAP CP#1977.00 4708 COLLEGE ACRES DRIVE SUITE 2 WILMINGTON.

Lil. `~R~j~`vq 0 300 1.000 SCALE IN FEET 1.2 Success Criteria. The restoration effort will be a success when the site has met all three wetland criteria as defined in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987). These criteria are: 1) hydric soils, 2) hydrophytic vegetation, and 3) wetland hydrology. The site ~~ is underlain by hydric soils (Johnston and Murville soils, Weaver 1977), so the immediate goals are concentrated on the re-establishment of a wetland ' hydroperiod and maintaining an acceptable density of trees at the end of the three-year monitoring period. Wetland functions such as surface water storage, nutrient cycling, and wildlife habitat will be restored as the well-drained riparian 1 bermed areas of Howe Creek and its unnamed tributary are returned to forested riparian wetlands. The following success criteria have been developed for the Mayfaire riparian wetlands restoration area. 1.2.1 Hydrology. The hydrology modifications made on the riparian restoration area were designed to restore the natural floodplain hydrology of the area. The restored wetland hydroperiod should either meet or exceed the criteria of 12.5 percent of the growing season with water levels within 12 inches of the surface or be frequently flooded for long duration (at least seven consecutive ' days of surface water) during a normal rainfall year. At least 0.74-acre of the 1.38 acres specified in the Mayfaire Compensatory Wetlands Mitigation Plan must meet the hydrology criterion to be considered successful. Standing water 1 and saturation within 12 inches of the surface are considered a positive indicator of wetland hydrology. 1.2.2 Vegetation. The Mayfaire riparian wetlands restoration areas were planted with several species of hardwoods. In accordance with the Mayfaire Compensatory Wetlands Mitigation Plan, the site design for tree composition included seven hardwood species planted at a density of 538 trees per acre with no more than 20 percent of any one species represented (CZR 2003). Vegetation success will be monitored for three years with vegetation plots scattered throughout restoration Area C. Success will be measured by tree ^ survival and species composition. Tree density will be at least 260 planted trees per acre at the end of the fifth growing season. If the trees per acre criterion is not met, remedial action will be taken. 1.3 Study Objectives. The primary study objectives are to monitor wetland hydroperiods and survival of planted trees within the restoration area. Shallow groundwater levels will be monitored for three years to evaluate whether the restoration area meets the hydrology success criteria. As an indication of planting success, a random sample of planted trees will be monitored for growth rates, mortality, and survival. Tree density and species composition will also be monitored to evaluate whether the area meets the vegetation success criteria. 1 1 ° 2.0 METHODOLOGY 2.1 Hydrology. Hydrology within the Mayfaire restoration site is monitored by measuring groundwater levels with four 32-inch shallow monitoring wells and one Remote Data Systems' EcotoneT"" semi-continuous groundwater recorder installed directly into the soil. One shallow monitoring well was installed in each of the two smaller mitigation sites (Areas A and B) and two were installed in Area C along with the Ecotone TM semi-continuous groundwater recorder (Figures 3, 4, and 5). In addition to the monitoring wells, two staff gages were installed in late May 2004; one adjacent to the unnamed tributary in the Area A, and one in Howe Creek in the vicinity of Area C (Figures 3 and 5). Staff gage information will be used to measure changes in water level of Howe Creek and the unnamed tributary. The As-Built Report (CZR Incorporated 2004) has complete descriptions of monitoring equipment. Hydrology data are collected monthly. Water table readings from the 1 shallow monitoring wells are recorded on standardized data sheets, examples of which are included in Appendix A. Hydroperiod interpretations were based on analysis of semi-continuous data, shallow well data, and rainfall data. Hydroperiods are based on the growing season given in the New Hanover County Soil Survey (Weaver 1977). Using the 28° F threshold and the 5-years- in-10 probability, the last freeze date in the spring is 27 February and the first freeze date in the fall is 26 November. Thus the growing season covers the 269- day period from 28 February to 25 November, inclusive. Wetland hydroperiods last at least 12.5 percent of the growing season (34 consecutive days). Marginal wetland hydroperiods span at least five percent of the growing season but less than 12.5 percent (13 - 33 consecutive days). 2.2 Soils. Soil profiles were taken at selected locations within Mayfaire prior to the restoration activities. Soil profiles were also taken after the restoration activities at each shallow monitoring well and EcotoneT"" location. Soil samples were taken with a 2.5-inch diameter hand auger when the wells were installed. Soil colors of the different horizons were determined using a Munsell Soil Color chart, and soil texture was described. CZR also collected soil samples for fertility and nutrient analyses from scattered locations within each mitigation area. Soil samples were dried and sent to the N.C. Department of Agriculture's Agronomic Division for testing. Nutrient levels and pH in all three restoration areas indicate that these sites are well-suited for planted hardwood seedlings. Soil results are included in the As-Built Report (CZR 2004). 5 `I W I W ~,~ I, ~ / Gam` W W ~.c~ / / gV \I/ W \I/ \I/ W W \I/ W /+ / W W W }/ / + \I/ W \I/ \I/ W W ~G / 1 ~ ` \I/ W \I, CJ W 2 4~ ti~ NOTE: BOLO CONTOUR LINE INDICATES RE-TOPOGRAPHIC `' W I W SURVEY DATE: 01-28-04 (TYPICAL) \ \\\\\ W k S/ck ~`N~ GAGE A F ~ r ~/ f CA~~ ~/ U ~ ~ ~ ~ gyFO \ lI ~ ~~_ i ~~-\ ~~eUTq R i ~ l I ._ ~~ y Si~T RIP-RAP ~~\ FfN ~ `\ M1 ~ r~i~ \ ~. 4 ~ ___ <~ ~ ~ o.isao ~~ .~_, ~~ ~ ~ ~ ~` ~~ ~__-, ~ i ti1~T ACCESS - - MAYFAIRE P_ROPERT_Y _L1NE MILITARY CUT OFF ROAD R.O.W.

The purpose of this sampling ' methodology is to monitor growth and survival of a random subset of the planted trees in order to extrapolate those parameters for the entire site. Three 0.02-acre sampling plots located north of Howe Creek in Area C were established and one 0.03-acre sampling plot south of Howe Creek in Area C was established at Mayfaire for a total sampling area of 0.09-acre. Planted trees were tagged with an identifying number and species names to assist in accuracy of ' measurements. The mitigation plan required monitoring in only the largest riparian mitigation area (Area C). An additional tree plot was added to the mitigation area to reach the required acreage of vegetation monitoring plots. Tree lot dimensions were ad~usted to ca ture the diversity of the planted p 1 p wetland zones as depicted in the planting design. Sampling acreage is consistent with guidance given in the 1993 USACE-Wilmington District Compensatory Hardwood Mitigation Guidelines. Figure 5 depicts the general layout of the tree sampling plots. r diameter of each to ed tree are measured and Height and root colla gg survival noted. Height is measured with a calibrated stake from the ground to the highest living bud on each tree, and root collar diameters are measured with calipers. Measurements are recorded on standardized tree data forms. A sample tree data form is included in Appendix A. The second annual fall measurements were collected during October 2005, the third annual measurements were collected 24 October 2006, and fourth annual measurements were conducted 23 October 2007, all near the end of the growing season, to monitor trends in growth and survival of planted trees. ' 2.3.2 Photographic Record. Six fixed-point photo stations were chosen to document changes in vegetation throughout the monitoring period. Representative baseline photographs were taken on 21 May and 10 June 2004. Annual photographs were taken at the time of fall vegetation monitoring. Fourth annual photographs were taken on 23 October 2007. Photographs were taken from the site corners and mid-section of the restoration area. These photo station locations were determined using GPS and therefore will remain the same throughout the monitoring period to ensure consistency of photo direction and location. Additional photographs were taken for comparison to show particular features of Area A and B restoration areas.

Monthly rainfall totals at Wilmington International Airport, New Hanover County, NC for 2007 are depicted in Figure 7. The Wilmington weather station is located approximately 8 miles west -northwest of Mayfaire. Monthly averages were derived from data collected daily at Wilmington Airport ' between 1976 and 2007, inclusive. Deviations (in inches) from 30-year average monthly totals were: +0.45 in January, -1.38 in February, -2.81 in March, -1.57 in April, -2.86 in May, -1.56 in June, -1.76 in July, -4.83 in August, -2.26 in September, -1.68 in October, -2.63 in November, and -0.53 in December. Most months were within the normal range (i.e. within one standard deviation of the 30-year average) except for March, May, August and November, which were more than one standard deviation below the average. Three-month rolling total rainfall at Wilmington Airport for 2007 are depicted in Figure 8. This rolling total is the total amount of rainfall for the three- month period ending with the month in question. For hydrological calculations, normal rainfall is defined as a three-month total within one standard deviation of ' the 30-year average. Rainfall was lower than normal April through December and above normal in January. Deviations (in inches) from 30-year average monthly totals were: +3.98 in January, -0.28 in February, -3.74 in March, -5.76 in April, -7.24 in May, -6.00 in June, -6.19 in July, -8.15 in August, -8.86 in September, -8.75 in October, -6.55 in November, and -4.81 in December. Using the three-month rolling total rainfall data, all of the growing season (except March) was below normal (i.e., within one standard coriation of the 30-year average). 3.2 Hydrology. Appendices B, C, and D contain the hydrology data gathered from the four shallow monitoring wells and the EcotoneT'" in the mitigation areas of Mayfaire. Dates of the longest wetland hydroperiod for each well location expressed as the percent of the growing season that the water table was within 12 inches of the surface are found in Table 1. Data from the fourth year of monitoring during normal or below normal rainfall indicate that wells B-1, ' C-1, C-2, and the Ecotone had a wetland hydroperiod of 269 days. Well A-1 had a wetland hydroperiod of 61 days Furthermore, the area containing wells C-1 and the Ecotone (the southwestern portion of Area C) had water above the ' ground surface for 100 percent of the growing period. The area containing well C-2 (the central portion of the northern section of Area C) had water above the ground surface most of the growing period. 3.3 Soils. The alluvial ri arian miti ti r p ga on a eas are mapped on the soil survey of New Hanover County as hydric Johnston and Murville soils (Weaver ' 1977).

Scientific names, common names, and wetland indicator status of all species planted in Mayfaire restoration areas are found in Appendix E. Vegetation data collected in the fall for the individual vegetation plots in Area C from 2004 through 2007 are provided in Appendix F. Survival of planted and tagged stems in Area C at baseline and fall 2007 is presented for each species in Table 2. Some seedlings were not identified to species because of poorly developed leaf characteristics, but all unknowns were dead by fall 2006. In Area C, some trees appeared to have been planted in poor health due to being planted late in the growing season (late May 2004), which may have contributed to tree mortality. Although seven species of hardwood trees [not including button bush (Cephalanthus occidentalis) and silky dogwood (Cornus annomum)] were planted, not all species are represented in the tree plots. At least for Area C it appears that bald cypress (Taxodium distichum) was planted with a density of more than 20 percent. At the 2007 fall sampling, 61 of the 97 tree stems tagged at baseline, or 63 percent, were alive. Bald cypress (98 percent), water tupelo (Nyssa aquatics) (100 percent), and swamp tupelo (Nyssa biflora) (50 percent) had the highest survival percentages. The single water tupelo was not alive at the time of the 2006 sampling but appeared to have regenerated by the time of the 2007 sampling. Also, an unknown tree that was dead in 2006 regenerated in 2007. The survival of swamp tupelo, button bush, and river birch decreased. To increase tree diversity and density in Area C, Freeman Landscaping planted 168 trees/shrubs spaced on 9-foot centers in the southwest cell of Area C (0.3 acre) on 5 April 2007. A list of species and number of stems planted are found in Appendix G. Average baseline and fall densities for planted tree seedlings are found in Table 3. Using the sample plots as a guide, density of the area was extrapolated to 650 trees per acre during the fall sampling, which is above the minimum 260 trees per acre required by the success criteria. Five tree species are represented and one, bald cypress, makes up more than 50 percent of the total density. The other species individually represent less than 10 percent of the total density. Average heights are presented by species for 2004 baseline, fall 2006 and 2007 in Table 4. Although button bush and silky dogwood are not considered in the trees per acre calculation, height and root collar diameter will continue to be monitored along with the other tagged trees. All species experienced average height decreases (Figure 9), ranging from 0.9 (bald cypress) to 75.5 (silky dogwood) percent, with an overall 5.6 percent decrease 15 1 1 1 1 1 1 1 1 1 1 1 1 1 Table 2.

The average height of bald cypress, which is more tolerant to flooding conditions than most species, decreased the least amount. The average height decrease for all species for the first growing season (March through November 2004) was -16.0 percent (Figure !~ 9). Average root collar diameters are presented by species for 2004 baseline, fall 2006 and 2007 in Table 5. Water tupelo (90 percent) followed by bald cypress (64 percent) had the highest average root collar increase (Figure 10). Silky dogwood (7 percent) experienced the least amount of expansion. Although no formal monitoring is required for herbaceous species planted in all areas, N.C. Division of Water Quality (NCDWQ) requested observational data be incorporated into the annual report. Approximately 60 percent of Plot 1 in Area C was visually estimated to be covered by Xyris sp., Juncus trigonocarpus (red-pod rush), Scirpus cyperinus (woolgrass), Fuirena squarrosa (umbrella sedge), Utricularia sp. (bladderwort), and algae in areas with standing water. Approximately 70 percent of Plot 2 and approximately 20 percent of Plot 4 contained the same species. Plot 3 was approximately 20 percent covered with an equal representation of woolgrass and red-pod rush. * Other species were in the area such as other Juncus species, Dicanthelium sp., Eleocharis sp. (spike rush), Hydrocotyle sp., and arrow arum (Pelfandra virginica). Area B contained several Juncus species, umbrella sedge, and arrow arum. Area A contained Typha latifolia (broad-leaved cattail), spike rush and Morelia cerifera (wax myrtle). The herbaceous and shrub layers in Area A are denser than other areas. The percent cover of herbaceous species in the vegetation monitoring plots has increased over the years. Vegetation in Area B appeared to be growing well after replanting trees in Area B in the summer of 2006. A retaining wall supporting the retention pond north of Area B collapsed in late September 2005 during a heavy rain, resulting in the deposition of a large sediment fan into the area, burying herbaceous cover and some trees (see photographs in Appendix G of CZR 2005). However, the area was mowed in late summer of 2007 affecting most of the herbaceous plants. 3.4.2 Photographic Record. The 2007 end of growing season photographs were taken on 23 October 2007. Representative baseline (26 October 2004) and fall fixed-point photo station photographs are in Appendix H. Additional photographs of mitigation Areas B and C are also located in Appendix H.

Hydrology data from 2007 and previous years indicate that all well locations, or 100 percent of the restoration areas, exceeded the greater than 12.5 percent hydrology criterion during periods of normal or below normal rainfall. 4.2 Vegetation. Bare-root hardwood seedlings were planted on an average of 6.5-foot spacings at a density of 1,031 trees per acre on the floodplain restoration areas of Mayfaire. The second annual planted tree survival 1 percentage was 73 percent and second year tree density was 725 trees per acre. The third annual tree survival percentage was 72 percent and third year tree density was 641 trees per acre. The fourth annual tree survival percentage was 63 percent and fourth year tree density was 650. While survival percentage has decreased each year, all years are above the minimum 260 trees per acre as ` required by the success criteria and this year's tree density increased slightly. ^ Based on the results of the fourth year (2007) and past years of tree monitoring, bald cypress dominates as the most prevalent species surviving, especially at Area C. This is likely due to the species' higher tolerance of flooding, which Area C has experienced. Vegetation at Area C appears to have been stressed by prolonged inundation prior to the lowered outlet as well as from the initial planting, which occurred later than planned due to grading/construction delays. Supplemental tree plantings occurred in Area C in the spring of 2007 in an attempt to ensure a successful diversity and density of trees within the wetland mitigation areas. 1 1 23 i ~, REFERENCES CZR Incorporated. 2003.

The tables contain manual water table measurements, Ecotone continuous water table measurements, and daily rainfall totals. The following notes and information will aid in interpreting these tables. ~ 1. Manual well measurements were made to the nearest quarter inch and are referenced to ground level (zero). 2. Ecotone water table readings were taken every 1.5 hours (16 times per day). Only the noon readings are given in these tables. Discrepancies between manual and electronic readings may be due to the different times readings were taken. All readings are displayed on the graphs in Appendix D. Printouts of the raw Ecotone data are on file in the CZR-Wilmington office. 3. Negative water table readings are below ground level and positive water table readings are above ground level. 4. Rainfall is from the Wilmington weather station and is the total rainfall for the 24 hour period ending at 8:00 am the day it is recorded. 1 r 1 1 1 Date MAYFAIRE WATER LEVEL IN INCHES ABOVE (+) OR

Mayfaire is allowed limited landscape activity at this site as described in Exhibit C of the Amendment to Permanent Conservation Easement attached to the permit (ID No. 200001359)-modification dated 24 February 2006. Condition AB.a states: "Permittee shall be allowed to create and maintain a visibility corridor over the 1.6-acre tract. In order to create and maintain this corridor, Permittee may remove all trees on the 1.6-acre tract, and trim all vegetation to a height of two meters, subject to the restrictions in sub-paragraphs b, c, and d." However, below canopy-level vegetation was trimmed to less than one meter tall, vegetation chipped on site and placed in piles on the site during the summer of 2006. Remedial Planting of the entire 1.6-acre tract occurred with a combination of native bare root and container hardwood saplings, and wetland shrubs. Planting of 860 trees and small shrubs, spaced on 9-foot centers, occurred 5 April 2007 (Table 1, Photos 1-12). Yearly vegetation monitoring was conducted on mitigation areas at Mayfaire in October 2007. Dominant vegetation in the conservation easement was also noted and photos of the area were taken (Photos 13-16) at that time. The canopy in October 2007 consisted of red maple, sweetgum, blackgum, and pond pine with red maple, red bay, and sweet bay sprouting in the cutover understory. The western third of the area was wetter, with inkberry as primary ground cover. Muhlenbergia sp. was the main ground cover in the eastern two thirds. Table 1.
