Introduction and Background Greene Environmental Services, LLC (GES) of Snow Hill, North Carolina added the La Grange site to the GES Neuse River Basin Umbrella Mitigation Bank. The La Grange Bank Parcel is located at the southwest intersection of NC 903 and Old Jason Road (SR 1501), north of LaGrange, in Lenoir County, North Carolina (Figures 1 and 2). The latitude/longitude coordinates of the site are approximately 77° 44.315 W and 35° 20.588N. The purpose of the nutrient mitigation bank is to improve water quality within the Neuse River Basin by reducing nutrient and sediment inputs to the watershed and provide off-site mitigation for development requiring nutrient offsets. The Bank Parcel is located within the Middle Neuse Watershed (HUC: 03020202). The site drains to Meeting House Branch (Stream Index # 27-72-3), which drains into Bear Creek (Stream Index # 27-72-(0.1)), a major tributary to the Neuse River. According to the NC Division of Water Quality Basinwide Information Management System, Meeting House Branch is classified as C; Sw, NSW. The Bank Parcel is 3.39 acres, including 0.87 acres of riparian buffer and 2.52 acres of nutrient offset acreage (Figures 3 and 4). The Bank Parcel was established under the terms and conditions of the GES Neuse River Basin Umbrella Mitigation Bank. The project site was in agricultural cropland until 2009 and was first planted with character species during March of 2010. This is the fifth annual monitoring report, and, pending approval, the final annual report. In 2015, a second mitigation bank was established immediately adjacent to the La Grange Bank Parcel. This bank is the La Grange Mitigation Bank, Phase II and will be monitored separately from the initial La Grange Bank Parcel and will be maintained with a separate mitigation credit ledger. 2. Monitoring and Results for Year 2017, Fifth Year Monitoring Effort As specified in the La Grange Bank Parcel Development Package (BPDP), this report represents the fifth year of vegetative monitoring. The BPDP requires the submission of an annual monitoring report each of five successive years. The La Grange Bank Parcel was initially planted with character trees in 2010 and 2011 at a rate of 413 seedlings per acre (Table 1). Supplemental plantings were done in 2012 and 2013 at a rate of 108 and 103 seedlings per acre, respectively. Thus prior to the submission of this first annual monitoring report an estimated total of 624 seedlings per acre had been planted on the 3.39 -acre parcel. In each of the two monitoring plots in the La Grange Parcel, tree stems were recorded by species in September 2017. Plot locations are mapped in Figure 5. Vegetation plot photo points were located at the northwestern corner of the plots (Figure 6). During the 2017 monitoring effort, a total of 45 trees representing ten species were recorded in the two monitoring plots, LAG -1 and LAG -2. The total average density was 910.9 trees per acre (Table 2). Thirty-seven of the 45 trees within the plots were from seedlings planted by GES. The average stem density for planted species was 749.0 tree stems per acre (Table 3). Thus eighty- two percent of the trees were planted species; bald cypress (Taxodium distichum) accounted for 41 percent of the planted trees followed, in decreasing order by river birch (Betula nigra) at 22 percent, black gum (Nyssa sylvatica) at 19 percent, and sycamore (Plantanus occidentalis) at 11 percent) (Table 4). White oak (Quercus alba), swamp chestnut oak (Quercus michauxii) and cherrybark oak (Quercus pagoda) each accounted three percent, each, of planted species total. Red maple (Acer rubrum), loblolly pine (Pinus taeda) and black oak (Quercus velutina) became established via natural colonization. Persimmon, green ash, yellow poplar, turkey oak, live oak, and pond cypress were planted on the La Grange Parcel but were not recorded in the monitoring plots. Stems of river birch and sycamore had the greatest average height (over 25 feet) among the ten species found within the plots (Table 5). A comparison of fourth year (2016) monitoring data to the fifth year (2017) indicted an increase in total stem density per acre in the monitoring plots from 870 stems per acre in 2016 to 911 stems per acre in 2017 (Table 6). For planted species, stem density was the same in 2017 as in 2016. For volunteer species, there was an increase of 40 stems per acre. For both total stem density and planted stem density, the 320 trees per acre success criterion was well -exceeded. M Table 1.

Overall Condition, Maintenance and Supplemental Plantings Vegetation establishment and growth during the 2017 growing season has been good at the La Grange Bank parcel. Growing conditions, e.g., adequate rainfall, length of growing season and fertile soils, have been advantageous since the initial plantings were undertaken. The height of some trees, especially sycamore and river birch, planted in 2010, now exceed 25 feet with diameters (dbh) of 8-15 cm. The majority of the Bank acreage is now under closed canopy and most grasses and herbaceous species have been shaded out or, expectedly will be within the next few growing seasons. Signage has been installed at key access locations identifying the Bank Parcel as a conservation area, contact information and listing activities that are not allowable as per a conservation easement. CI 4.0 Riparian Buffer and Nutrient Offset Potential The 3.39 -acre, La Grange Bank Parcel consists of 0.0.87 acres of potential Neuse riparian buffer credits and 2.52 acres of nutrient (nitrogen) credits (Table 7). A separate ledger of credit releases and transactions is kept by Greene Environmental Services, LLC. Table 7.
