BURNT MILL CREEK MANHOLE ACCESS PROJECT
WETLANDS INVESTIGATION

Introduction

Limited access to wastewater infrastructure along the east side of Burnt Mill Creek in Wilmington, NC,
severely impedes routine maintenance activities required to maintain necessary levels of service. The
36-inch interceptor runs behind homes fronting Klein Road and N. 21st Street on the west side of the
Princess Place neighborhood (Figure 1). An existing, gated service road is built on fill and generally
follows the bends of Burnt Mill Creek, approximately twenty feet from the top of the stream’s east bank. A
jurisdictional wetland lies between the service road and the existing sewer line. This report documents
findings of investigations into the presence and extents of jurisdictional waters and wetlands in the
vicinity of the proposed project.
Currently, access to the sewer line by maintenance vehicles is limited to a crossing at Shirley Road and
a crossing at Princess Place Drive, one-half mile to the south. This project will install critical access for
maintenance vehicles from the existing service road to three manholes between the two existing access
points. Each of the three new access lanes will cross a wetland that is situated between the existing
service road and the sewer line.
Burnt Mill Creek drains much of downtown Wilmington and flows north into Smith Creek. It is in the
Northeast Cape Fear sub-basin, HUC 03030007. The subject wetland trends northwest to southeast for
approximately 2600 feet. It is bounded to the north by a railroad right-of-way and to the south by urban fill
supporting businesses on Princess Place Drive. The wetland ranges in width from about 75 to 150 feet
for most of its length and widens to nearly 300 feet at the southeast end. The parcel is owned by the
Cape Fear Public Utility Authority and is part of Burnt Mill Creek Park.
The three new maintenance lanes will be installed between the existing service road and the sewer line
and will be approximately fifteen (15) feet in width. Fifteen feet is the minimum width needed for safe
passage of service trucks that may need to access manholes at night and during inclement weather.
Construction will require narrow strips of fill across the wetland, from the service road fill to manholes on
the 36-inch interceptor. The three access areas are called out on the Vicinity Map on Sheet 1 of the
plans. Total unavoidable wetland impacts are 0.16 acre. Access 1 is at the southern end of the project
and will impact 0.09 acre of wetland and is 265 feet in length. Access 1 is slightly longer due to curves
in the alignment designed to avoid a large cypress tree. Access 2 is in the middle of the project, will
impact 0.03 acre of wetland and is seventy-nine (79) feet in length. Access 3 is at the north end of the
project, will impact 0.04 acre of wetland and is 102 feet long.
As described below, the boundaries of jurisdictional wetlands are consistent along the fill embankment
supporting the existing access road on the west side of the wetland, and the interceptor right-of-way at
the back of residential properties on the east side. Because the entire footprint of each proposed access
lane will impact the wetland, a delineation of the entire wetland boundary is of little value. Therefore
wetland boundaries were delineated only at the three crossings. Field investigations were completed on
December 18, 2019 to characterize the wetland to be impacted and to identify potential design
considerations to reduce the severity of necessary impacts.
Wetland impacts cannot be avoided entirely because there is no other route to the manholes except from
the existing service road. Impacts to wetland vegetation have been minimized in the layout of the access
lanes, which avoids large trees and cypress knees as much as possible. Impacts to wetland hydrology
are minimized by the installation of culverts under each access lane, which will allow surface water to
flow and circulate within the wetland system.

Methods
Approximate boundaries of the three access lanes were loaded into Googlemaps from .kmz files.
Ambulatory reconnaissance proceeded southeasterly from the service road at Shirley Road down to
Princess Place Drive. The wetland was entered at each of the three access lane locations and
observations of vegetation, hydrology and soils were recorded according to the 1987 Corps manual and
appropriate regional supplement. Each maintenance lane was typically walked from the existing access
road to the existing interceptor, and observations were not strictly limited to the 15-foot widths of access
lanes.

Summary of Findings
Vegetation, soils and hydrology were consistent for the wetland system through Access 2 and Access 3.
Hydrology appears to be driven primarily by groundwater, supplemented with surface runoff from the
neighborhood to the east. However, multiple concrete pipes cross the wetland and discharge into Burnt
Mill Creek, so it appears that most stormwater is collected from streets and not discharged into the
wetland. The surface runoff would therefore be limited to those homes with backyards abutting the sewer
easement.
Bald cypress (Taxodium distichum) dominates the tree stratum for most of the system and the canopy is
open. The sapling-shrub layer is limited to the margins of the wetland near the service road spoil berm
and close to the sewer line. Locally dominant sapling and shrub species are sweetgum (Liquidamber
styracaflua), elm (Ulmus sp.), privet (Ligustrum sinense), myrtle (Myrica cerifera) and tupelo gum (Nyssa
aquatica). Greenbrier (Smilax bona-nox) occasionally grows close to the berm. Patches of Sagittaria
spp. and cattails (Typha angustifolia) occur in open water and a few clumps of sedges (Carex spp.) were
observed.
The amount of standing water decreased significantly toward the southeastern part of the project area.
Access 1 includes higher ground that was not inundated at the time of field observations. However, as
indicated on the Wetland Determination Data Form for Plot 2, this access corridor exhibits wetland
characteristics for all three parameters. At Plot 2, free water rose to five (5) inches below the surface
after thirty (30) minutes in a soil boring advanced into some of the higher elevation ground The diverse
hydrologic conditions at Access 1 are reflected in the vegetation as loblolly pine (Pinus taeda) and water
oak (Quercus nigra) dominate the tree stratum and sweetbay magnolia (Magnolia virginiana) is common
in the sapling layer. Access 1 also includes significant surface water, with about 30 percent of the
corridor being inundated at the time of the field visit. The inundated area is at the east end of the access
corridor and is dominated by patches of cattails (Typha angustafolia) and smartweed (Persicaria
hydropiperoides).
Soils in the project area are mapped as Johnston series (JO, Figure 2). Johnston soils are very poorly
drained mucky loam that occur on floodplains. Johnston soils are hydric, frequently flooded and
frequently ponded. Field observations were consistent with Johnston soils. Southeast of the project
area, behind and to the north of the auto service business on Princess Place Drive, soils are mapped as
Urban Land.

Adjacent uplands are disturbed areas. To the west of all three access corridors is the embankment from
the existing access road along Burnt Mill Creek. The embankment itself is dominated by privet, small
elm (Ulmus Americana), sweetgum and greenbriar. The road surface is frequently mowed grass. East of
the proposed gravel access corridors is an embankment that leads up to maintained residential
backyards and contains the sanitary sewer line. The sewer right of way and yards are also frequently
mowed grass.
