1650 Prepared By GrccnVcst /1 lat Swamp, LLC 4405 DeWees Court Raleigh NC QW T\/T Quality Woods D"Gto` December 2011 Executive Summary The third year (2011) annual maintenance and monitoring of the Flat Swamp Mitigation Bank Neuse and Nutrient Offset Buffer Restoration Parcel (herein referred to as Bank Parcel ) is complete The purpose of the Bank Parcel is to improve water quality through the restoration of riparian and non riparian buffers as proposed in the Bank Parcel Development Package (BPDP) (GV 2009) and supporting documentation The Flat Swamp watershed has been extensively impacted by clearing ditching ongoing agricultural practices and road building over the past 100 years These activities have obliterated many of the historical stream and wetland systems including the riparian and non riparian wetlands as well as small coastal plain zero first and second order streams that once flowed to the Neuse River The site is in the upper reaches of the Flat Swamp Creek watershed and therefore has a large influence on the water quality and habitat in Flat Swamp Creek Core Creek and ultimately the Neuse River The primary objective is to establish Nutrient Offset and Neuse Buffer credits provide mitigation for Neuse Buffer and Neuse Nutrient offset payments within the Neuse River Basin and /or to sell resulting credits to third parties public or private The FSB is located in the North Carolina Division of Water Quality (NCDWQ) sub basin 03 04 08 of the Neuse River Basin More specifically the site is located within US Geologic Survey (USGS) 8 digit hydrologic unit code (HUC) 03020202 and 14 digit HUC 03020202080020 Flat Swamp creek originates approximately 3 2 miles southwest of Fort Barnwell and 4 5 miles northeast of Dover in Craven County North Carolina As of the end of the second growing season (2010) for the Flat Swamp Neuse and Nutrient Offset Buffer Restoration Project annual monitoring is complete of the nearly 250K bare root tree seedlings planted on a ^7x10 spacing ( -622 trees /ac) consisting of character species proposed in the BPDP (2009) The third (3 d) growing season has resulted in continued rapid growth of a healthy and vigorous stand of character trees According to third (3 d) year vegetation plot data from thirty eight (38) one (1) are plots tree survival is between 12 and 22 trees /1 are equating to 486 to 891 trees /ac (79 100% survival) The average survival for all character trees 700 trees /ac And the average diameter and height is 39 6 mm (1 5 in) and 234 9 cm (7 7 ft) respectively across all character species The project target goal is 320 trees /ac at the end of 5 years and therefore the project has met success criteria again for the third (3 d) monitoring year within each plot and overall First second and third year vegetation data shows there has been significant leaf and stem growth establishing that the buffer restoration was successful during the critical period following construction and after the second year during heavy competition from herbaceous plants Continued monitoring of the site shows additional leaf and stem growth late into the growing season thus improving chances for survival and rapid growth for subsequent years Flat Swamp Mitigation Bank GreenVest /Flat Swamp LLC Neuse & Nutrient Offset Buffer Restoration Parcel Annual Monitoring Report Year 3 2011 Table of Contents Executive

Neuse & Nutrient Offset Buffer Restoration Parcel Annual Monitoring Report Year 3 2011 10 Introduction The Flat Swamp Mitigation Bank Neuse and Nutrient Offset Buffer Restoration Parcel third (3 � year maintenance and monitoring report (2011) is complete The purpose of the Bank Parcel is to improve water quality through the restoration of riparian and non riparian buffers as proposed in the Flat Swamp Mitigation Bank Parcel Development Package (GV 2009) and supporting documentation The Bank Parcel is located in North Carolina Division of Water Quality ( NCDWQ) sub basin 03 04 08 of the Neuse River Basin More specifically the site is located within US Geologic Survey (USGS) 8 digit hydrologic unit code (HUC) 03020202 and 14- digit HUC 03020202080020 Flat Swamp creek originates approximately 3 2 miles southwest of Fort Barnwell and 4 5 miles northeast of Dover in Craven County North Carolina Flat Swamp Creek is a tributary of the Neuse River and flows east from the site intersecting Core Creek before emptying into the south side of the Neuse River The FSB is located in the headwaters of Flat Swamp Creek (Latitude 35 degrees 15 minutes 10 96 seconds N and Longitude 77 degrees 22 minutes 04 05 seconds E) The site is bounded by Dover Fort Barnwell Road (SR 1262) to the north and west Jonestown Road (SR 1258) and Camp Oak Road (SR 1261) to the east, and Dover Bay to the south (Appendix I Figure 1) The Flat Swamp Creek watershed has been extensively impacted by clearing ditching ongoing agricultural practices and road building over the past 100 years These activities have obliterated many of the historical stream and wetland systems including the riparian and non riparian wetlands as well as small coastal plain zero first and second order streams that once flowed to the Neuse River The site is in the upper reaches of the Flat Swamp Creek watershed and therefore has a large influence on the water quality and habitat in Flat Swamp Creek Core Creek and ultimately the Neuse River The primary objective is to establish Nutrient Offset and Neuse Buffer credits provide ntigation for Neuse Buffer and Neuse Nutrient offset payments within the Neuse River Basin and /or to sell resulting credits to third parties public or private As constructed the Bank Parcel will provide 20 34 acres Neuse Buffer restoration and 285 91 acres of Nutrient Offset Buffer restoration A Bank Parcel Development Package (GreenVest 2009) and Neuse River Riparian Buffer and Nutrient Offset Mitigation Banking Instrument were completed and executed by NCDWQ for the Bank Parcel in 2009 and amended per as built survey in December 2011 Riparian headwater system improvement is accomplished through the restoration of forested buffers along Jurisdictional streams and watercourses draining to Jurisdictional streams Restoration of the riparian and non riparian areas using strategic vegetation planting practices provides stream bank stability stream shading water quality improvements through nutrient uptake and sediment filtering as well as providing wildlife habitat These riparian buffers will be restored by planting appropriate native species of trees shrubs and herbaceous vegetation in zones specific to landscape position topography and hydrology As of the end of the third (3 9 growing season for the Flat Swamp Neuse and Nutrient Offset Buffer Restoration Project (2011) annual monitoring is complete of the nearly 250K planted bare root tree seedlings on a 7x10 spacing ( -622 trees /ac) consisting of character species proposed in the BPDP
