1.0 Project Location and Description
Greene Environmental Services, LLC (GES) of Snow Hill, North Carolina expanded a mitigation
bank at near La Grange, NC to include additional acreage for riparian buffer and nutrient offset
credits. The original bank, La Grange Bank Parcel is 3.39 acres and is in its third of five post -
implementation monitoring years. As with the initial project, the new acreage is included in the
Greene Environmental Services Neuse River Basin Riparian Buffer and Nutrient Offset Umbrella
Bank. The new, expansion project is named the La Grange Mitigation Bank, Phase II. It is
immediately adjacent to the initial La Grange Bank Parcel and is situated southwest of the
intersection of NC 903 and Old Jason Road (SR 1501), north of La Grange, in Lenoir County,
North Carolina (Appendix A: Figures 1, 2, 3 and 4). The latitude/longitude coordinates of the site
area approximately 350 20'30.00" N and 77°47'21.56" W. The purpose of the Phase II mitigation
bank expansion is to improve water quality within the Neuse River Basin by reducing nutrient and
sediment inputs to the watershed and providing off-site mitigation for development requiring
nutrient offsets.
The Phase H bank parcel is located within the Middle Neuse Watershed (HUC: 03020202).
Stormwater runoff from this site drains into Meeting House Branch (Stream Index # 27-72-3)
and via a farm drainage ditch and maintained canal system (un -named tributary, UT). Meeting
House Branch discharges to Bear Creek (Stream Index # 27-72-(0.1)), a major tributary to the
Neuse River (Appendix A: Figures 1 and 2).
The Phase II parcel is 3.50 acres. Of this 3.50 acres, 2.97 acres (6,750.87 lbs -N) were restored to
generate nutrient offsets and 0.52 acres (22,620.63 ft2) were restored to generate Neuse Riparian
Buffer Mitigation. The buffer restoration acreage was reduced by 30.57 ft2 as compared to the
BPDP. For reporting purposes, all acreages are rounded to the nearest hundredth of an acre.
Riparian buffer mitigation acreage was established in two sub -tracts labelled A and C in the
survey plat provided in Appendix A: Figures 4 and 5. Sub -tract A is 0.03 acres (1,491.00 ft2)
and buffers southerly flowing Meeting House Branch; sub -tract C is 0.49 acres (21,129.63 ft2)
and buffers the westerly flowing unnamed tributary to Meeting House Branch. Nutrient offset
acreage was established in two sub -tracts, B and D. Sub -tract B is 0.16 acres along the unnamed
3
tributary to Meeting House Branch and sub -tract D is 2.81 acres along a drainage ditch at the
eastern border of the Phase II tract that discharging to the UT that flows into Meeting House
Branch, and adjacent to the sub -tract C riparian buffer area. The riparian buffers extended from
the top of the ditch -banks 50 feet perpendicular to the buffered steam segments. The nutrient
offset acreage extended from the top of the ditch -banks a minimum of 50 feet and a maximum of
200 feet perpendicular to the buffered stream segments or to the border of Phase I. A 0.06 -acre
(2,613.60 ft2) triangular portion of the site adjacent to L-13 on the survey plat is beyond the 200 -
foot allowable limit for mitigation credit thus is not included in the mitigation credit calculations.
However, this isolated portion had to be purchased by Greene Environmental Services, LLC to
avoid the need to provide access an access easement concerns. This Phase II bank parcel was
established under the terms and conditions of the Greene Environmental Services Neuse River
Basin Riparian Buffer and Nutrient Offset Umbrella Bank.
The Phase II parcel was previous agricultural cropland and approximately one acre was planted
with bald cypress and river birch saplings during March of 2010, at which time staff from the
NC Department of Environment and Natural Resources (now renamed the Department of
Environmental Quality), Division of Water Resources visited the site and determined that it was
suitable for mitigation. Katie Merritt with DWR visited the site in June of 2013 and determined
this Phase II acreage was still suitable for mitigation purposes.
2.0 Plantings of Seedlings the La Grange Mitigation Bank, Phase II
In an effort to restore some ecological functions and improve water quality in the local and
regional watersheds, the La Grange Mitigation Bank, Phase II project site was planted with
seedlings of native trees species and placed under permanent conservation easement. As a result
of these actions, the project site has been taken out of agricultural production, soils should
become better stabilized, and nutrient loading in adjacent streams should be reduced. Seedlings
of character tree species were planted in three installments during separate years prior to the
creation of the 3.50 -acre, La Grange Mitigation Bank, Phase II. In late winter of 2010 and 2014,
seedlings of river birch and bald cypress were planted in portions of the area that was to become
the Phase II expansion acreage (Table 1). In late winter of 2014 and 2015, yellow poplar, black
4
gum and sycamore were planted in the Phase II tracts. Also, in March of 2015, three oak species:
overcup oak, cherrybark oak and Shumard's oak were planted in the Phase II acreage.
Considering all planting installments, bald cypress and sycamore were the most frequently
planted species with the oak species least frequently planted (Table 1). A total of 1890 seedlings
were planted in the Phase II expansion acreage for an estimated density of 541.5 seedlings per
acre.
Plantings by sub -tract were as follows: riparian buffer sub -tracts A and C were planted in 2015
with a mix of yellow poplar, black gum, sycamore, overcup oak, cherrybark oak and Shumard
oak, from the top of the stream bank outward to 50 feet. Nutrient offset sub -tract B was planted
in 2015 with the same tree species from the top of the stream bank to the border of the pre-
existing La Grange Bank Parcel (roughly 30 feet). Nutrient offset sub -tract D was planted the
same mix of species from the existing stand of trees (mostly bald cypress and river birch)
initially planted in 2010, to the pre-existing La Grange Bank Parcel boundary or up to 200 feet
from the top of the ditch bank. Survival rates of the planted seedlings were assessed by counting
stems in two 100m2 monitoring plots that were established in representative stands of the project
site; the monitoring assessment for this first annual report was conducted on September 28, 2015.

3.0 Monitoring Plot Survey Results
Two l Om x l Om (0.0247 acre) monitoring plots were established in the 3.50 -acre, La Grange
Mitigation Bank, Phase II project area (Appendix A: Figure 5). Monitoring plot LAG -3 was
established in a portion of Phase II that was planted with bald cypress and river birch
seedlings in 2010 and one yellow poplar planted in 2015. A plot survey in September 2015
indicated that there were eleven planted character trees in LAG -3 for an estimated density of
445.3 trees per acre (Table 2). Bald cypress was the most frequently encountered species
with seven stems in the plot; there were three stems of river birch and one yellow poplar.
One red maple was found in the plot but was not included in the plot data analysis. The
second monitoring plot, LAG -4, was situated in a portion of the Phase II expansion area that
was planted with seedlings in 2015. Three species were found in the monitoring plot,
sycamore, cherrybark oak and Shumard oak. A total of twelve seedlings were found in the
plot for an estimated density of 485.8 seedlings per acre (Table 2). All three species in plot
LAG -4 were equally represented with four stems each. The average density between the two
monitoring plots was 465.3 seedlings/trees per acre.
Stem heights in monitoring plots averaged 5.1 meters in plot LAG -3 and 0.7 in plot LAG -4
(Table 3). Stem heights were higher in Plot LAG -3 since most of these trees were five years
older than those in Plot LAG -4.
A comparison of survivorship in monitoring plots between those reported in the La Grange
Mitigation Bank, Phase II, "As -Built Report" from March 2015 to the survey conducted in
September 2015 and reported in this document indicated that Plot LAG -3 increased by one
stem with the addition on a yellow poplar that had not been recorded in March 2015 (Table
4). Plot LAG -4 decreased by two stems with the death of two sycamore seedlings. Overall,
there was a decline of 20.5 stems per acres for an average 465.3 per acre in September, 2015.
The success criterion of 320 stems per acre has been succeeded by approximately 145 stems.

The monitoring plots in the Phase II acreage were photo -documented using digital
photography imaged from the northwestern corner of the plot. All seedlings or trees were
flagging and their position within the plots were mapped (Appendix B).

Bank, Phase II.
4.0 Monitoring, Maintenance and Supplemental Planting
The La Grange Mitigation Bank, Phase II will be monitored seasonally during 2016 to ensure
that the terms of the conservation easement are not being violated due to unauthorized activities
at the site. Based on monitoring plot field data collected in September, 2016, the Mitigation
Bank is performing adequately. However, general observations of site conditions in some
locations outside of the monitoring plots indicated inconsistent seedling establishment in limited
locations. Pending approval of DWR staff, Greene Environmental Service, LLC proposes
supplemental planting with seedlings of appropriate species during the winter 2016 planting
season.
