Pamlico River Basin Construction activities, in accordance with the approved restoration plan, began March 14, 2007, and were completed on May 14, 2007 The resulting features include a main swamp run and adjacent areas of lower elevation that retain flood water for extended periods Tree and shrub planting on the project site occurred in May, 2007 using bare -root seedlings and containerized stock from a species list that produced a diverse species nux across the site and throughout the various elevations Six water level monitoring gauges are installed at varying elevations throughout the site to measure subsurface water elevations Two additional gauges are installed at reference sites for hydrology comparison In 2011, all of the monitoring gauges met the hydrologic success criterion of maintained groundwater levels within 12 inches of the soil surface for 21 consecutive days during the growing season Four vegetative monitoring plots are installed and permanently monumented, one coincident with each of monitoring gauges 1 through 4 Their locations ensure an accurate sampling of the entire vegetative community Each plot is a 10m X 10m square, as recommended by the CVS- EEP Protocol for recording vegetation sampling In this fourth year of monitoring, all four plots met the Year 5 success criterion of 260 living planted stems per acre Table ES -1 shows the levels of success attained by each of the water level monitoring gauges and the vegetation plots since monitoring began Success criterion for hydrology is 8% of the growing season (21 days) Table C -1 in Appendix C has a detailed breakdown of hydrologic success Success criterion for the vegetation plots is 260 live stems per acre (the year 5 criterion for survival) Table ES -1 Project Success Summa (longest hydropenod as a percent of the growing season) Gau a Percent Success Vegetation Plot Percent Success 1 2 3 4 5 6 7* 8* 1 2 1 3 4 Year 1 (2008) 38 33 36 34 35 36 61 16 100% Y Y N N 50% Year 2 (2009) 55 35 30 51 35 45 46 49 100% Y Y Y Y 100% Year 3 (2010) 12 18 19 18 18 18 100 18 100% Y Y Y Y 100% Year 4 (2011) 30 1 21 1 27 1 21 1 21 1 28 1 21 15 100% Y I Y Y Y 100% * Gauges 7 & 8 are reference gauges and not included in Percent Success Figures in GREEN made hydrology for 8% of the growing season, figures in RED did not Mason Property Wetland Mitigation Project 1 Albemarle Restorations LLC 201 I Momtonng Year 4of 5 I Protect Background 10 Proiect Obiectives The goal of the Mason Property Mitigation Project was to create both riverine and non - riverine wetland systems that will accomplish several goals Primary among those goals is the establishment of functioning wetlands that will aid in flood attenuation and improve water quality on site and downstream The project is to serve as compensation for wetland loss in the Tar - Pamlico River Basin The restoration plan was developed and implemented to ehmmate pattern drainage and restore topography and hydrology that more closely resembled that of similar undisturbed land Construction resulted in the development of a broad, frequently flooded swamp run following the historical path as evidenced by aerial photographs and signature topography Subsequent planting was designed to restore a wetland forest ecosystem that is typically found in the immediate area characteristic of siirular soils, topography and hydrology The specific project goals and objectives include 1) Provide floodflow attenuation 2) Water quality improvement through sediment, toxicant, and nutrient retention and reduction 3) Slow over bank flow rates and provide storage and desynchromzation of flood waters 4) Alleviate downstream flooding issues by lessening the effect of pulse or flashy flows 5) Provide shading through forest cover to reduce algae growth and associated low dissolved oxygen levels in surface water moving through the site 6) The production and export of food sources 7) The creation of wildlife habitat and recreational opportunities 20 Protect Structure, Restoration Type. and Approach Table I lists the estimated wetland acreage by community type to be restored on the Mason Property The mitigation plan provides for the restoration of 16 0 acres of riverine wetlands and 20 0 acres of non- riverme wetlands The 36 0 acre easement area is located within the boundaries of the larger Mason farm which has been used for row crop production The project area was bisected by a deep drainage ditch that acted as a stream that ran from north to south through the property Degradation to the channel and surrounding areas by past agricultural activities, including channel straightening and planting of row crops up to the channel edges had eliminated any significant natural habitat on the site and allowed excessive nutrient and sediment accumulation in the channel Construction, in accordance with the approved restoration plan, began in March of 2007 and was completed in May of 2007 The resulting features and topography allow for frequent over bank flooding of the newly created swamp run, which in turn allows for adjacent areas that are lower in elevation to retain water even after stream flow returns to normal Mason Property Wetland Mitigation Project 2 Albemarle Restorations LLC 2011 Monitoring -

Year 4of 5 planted stems include the depth of salt penetration into the trees' root zone, the relative salinity levels and whether or not the leaf buds break open in the fall of 2011 Late bud break could deplete root carbohydrate stocks which may adversely affect spring leaf -out in 2012 Live buds were less obvious on buttonbush and willow oak, though many of these stems are tall enough that their uppermost buds may have escaped serious damage Coffeeweed (Sesbania herbacia) appeared to have re- emerged during the 2011 growing season but was completely defoliated during the hurricane in August, 2011 It remains to be seen how much viable seed it produced and to what extent it will be a problem in 2012 12 Vegetation Momtonng Plan View (Integrated) Due to the fact that the entire project area suffered damage, Appendix D contains photos instead of a map that more accurately illustrate the damage caused by salt water flooding during Hurricane Irene in August, 2011 If not for the salt damage, few, if any problem areas would have been reported 20 Wetland Assessment The hydrologic success criterion is to achieve a nummum of 21 consecutive days where the groundwater level is within 12 inches of the soil surface during the growing season The growing season for this site is from March 11 to November 27, a period of 261 days (WETS Table for Belhaven, Beaufort County, NC) Success for any particular monitoring location is to show soil saturation to within 12 inches of the surface for 21 consecutive days during that period Six continuous monitoring gauges are deployed across the site and two more are installed in reference areas All six gauges met the success criteria for the site in 2011 as did the two reference gauges 21 Wetland Discussion and Problem Areas Drainage from the project area can only occur during tunes when water levels onsite are high enough to overcome the level of the retaining structure at the outfall end of the project and the level of the water beyond the outfall end is low enough to accommodate additional runoff which is dependant on daily tidal fluctuations This combination causes the site to maintain robust hydrology for long periods and even during seasons when rainfall is less than average Salt water intrusion was suspected of causing damage to planted stems in the past, but the photos in Appendix A illustrate beyond a doubt that this is indeed a potential problem Also, refer to the hydrographs in Appendix D for peak high water marks during Hurricane Irene in August, 2011 Gauges 3 and 6 recorded the highest water mark during the storm at 4 0 feet above ground level The other gauges recorded various water levels from 2 6 feet to 3 9 feet above ground level These lugh water levels were very short- lived, but lasted long enough to cause damage to foliage Green, live buds were observed on many stems during data collection which indicates the salt damage may be superficial The vegetation will be reassessed after leaf -out in 2012 Mason Property Wetland Mitigation Project 10 Albemarle Restorations LLC 2011 Momtonng Year 4of 5 22 Wetland Monitoring Plan View (Integrated) The photos in Appendix D illustrate the problems discussed above Table VI Hydrology and Vegetation Mason Pro a rty Wetland Miti Criteria Success by Plot anon Pro ect/EEP #D06001 Well Hydrology Success Met Hydrology Mean Vegetation Plot Vegetation Success Met Vegetation Mean 1 Y (30 %) 100% 1 Y 100% 2 Y (21 %) 2 Y 3 Y (27 %) 3 Y 4 Y (21 %) 4 Y 5 Y (21 %) No Plot N/A 6 Y (28 %) No Plot N/A 7 Y (21%) No Plot N/A 8 Y (15 %) No Plot N/A 3 0 Protect Success Discussion Achieving successful hydrology on the Mason project has not proven to be difficult Tree survival and growth have been more of a challenge due to the heavy herbaceous cover, high water levels which hamper seedling development and now, as shown by the photo evidence from September, 2011, saltwater intrusion caused by wind - driven high tide events Tree survival in 2011 appeared to be at a sustainable level but it remains to be seen if the planted stock can overcome the salt water damage from Hurricane Irene in August, 2011 Gauges 1, 2 and 3 and their corresponding vegetation plots are located on areas of the project that are most likely to experience prolonged inundation and occasional exposure to saltwater The herbaceous cover at these gauges /plots is primarily cattails (Typha latifolia) and coffeeweed (Sesbania herbacta), which are largely absent at gauge /plot 4 where tree growth appears to be better on average and the vegetative cover is more diverse The site topography is such that the area around gauge /plot 4 is less subject to minor flooding, and probably less subject to saltwater intrusion though still subject to total inundation during very wet periods or excessively high tides The 2011 vegetation assessment was done ten days after Hurricane Irene passed through the area and as can be seen on the hydrographs, the entire site was still flooded to a depth of nearly twelve inches Given the past hydrologic performance of this project, it is likely the site will remain flooded, to some extent, until drier weather returns in the summer of 2012 Upcoming fall rains should help dilute the salt content which may prove beneficial to continued tree survival and growth III Methodology Section Year 4 monitoring for the Mason project occurred in 2011 Monitoring and vegetation sampling procedures were established in the mitigation plan for this project and no deviations were made Mason Property Wetland Mitigation Project 11 Albemarle Restorations LLC 2011 Monitonng Year 4of 5 Appendix A Vegetation Data Tables Site Photos 1 Vegetation Data Tables Table 1 Project Summaz Report Prepared By Ashby Brown Date Prepared 9/8/2011 17 00 DESCRIPTION OF WORKSHEETS IN THIS DOCUMENT ------------ Metadata This worksheet, which is a summary of the project and the project data Vigor b Spp Frequency distribution of vigor classes listed by species Damage by Spp Damage values tallied by type for each species Damage by Plot Damage values tallied by type for each plot ALL Stems by Plot and Species Count of total living stems of each species (planted and natural volunteers combined) for each plot, dead and nussing stems are excluded PROJECT SUMMARY------------------------------------- Pro ject Code D06001 Project Name Mason Riverme Desch tion Mason Riverme wetland project in Hyde county, NC River Basin Tar- Pamlico Sampled Plots 14 Table 2 Vigor b S ecies Species 4 3 2 1 0 Missing 1 Ce halanthus occidentahs Clethra almfolia 3 1 8 1 Myrica cerifera Clethra alnifoha 1 1 N ssa biflora 1 1 8 N ssa biflora Quercus bicolor 1 1 38 1 6 Quercus bicolor 2 Taxodium distichum 34 2 1 TOT Quercus phellos 48 10 2 4 Taxodium distichum 32 2 Myrica cerifera 1 TOT 7 38 10 Table 3 Damage by Species Species All Damage Categories (no damage) Hurricane Ce halanthus occidentahs 4 1 3 Clethra almfolia 1 1 8 Myrica cerifera 1 1 1 N ssa biflora 1 1 8 TOT Quercus bicolor 1 1 38 Quercus phellos 6 4 2 Taxodium distichum 34 2 32 TOT 7 48 10 38 Table 4 Damage by Plot lot All Damage Cate ones (no damage) Hurricane D06001 -ABET -0001- ear 4 11 1 10 D06001 -ABET -0002- ear 4 14 6 8 D06001 -ABET -0003- ear 4 13 1 12 D06001-ABET-0004-year 4 10 2 8 TOT 4 48 10 38 Table 5 Stem count by lot andspecies Feature/Issue Species Total Planted Stems # plots avg# stems Plot 1, year Plot 2, Plot 3, year 4 Plot 4, year 4 Cephalanthus occidentalis 3 3 1 1 1 1 Myrica cenfera 1 1 1 1 Quercus phellos 2 1 1 2 2 Taxodium dishchum 32 4 8 9 5 11 7 TOT 4 38 4 10 8 12 8 Average per acre 392 412 330 495 330 Table 6 Vegetation Problem Areas Feature/Issue Plot Probable Cause Photo # Possible mortality caused Entire project area Saltwater intrusion during VPA 1 2 3 by saltwater intrusion Hurricane Irene View from Gauge 1 shows project is completely flooded in March 2011.

Vegetation across the project site shows stress and premature leave browning or leaf drop due to salt water intrusion during the storm. The long -term effects of this salt damage are unknown at this point. Typical example of damage from salt water flooding post Irene. Entire project site was inundated with salt water causing widespread browning of vegetation. Typical browning of the vegetation on the project site. Some live leaf material above the 4.0' high water mark appears to have survived.
