2. Waters of the United States
a) Water Resources
Water resources in the study area are part of the Neuse River Basin (U.S. Geological
Survey [USGS] Hydrologic Unit 03020204). Six jurisdictional streams and two jurisdictional
tributaries were identified within the study area (see Table 10). The locations of these water
resources are shown on Figures 2A and - 2C. The physical characteristics of each stream are
provided in Table 11.

There are no designated High Quality Waters (HQW), Outstanding Resource Waters
(ORW), or water supply watersheds (WS -I or WS -II) within a 1.0 mile downstream of the study
area. The North Carolina 2012 Final 303(d) list of impaired waters identifies no streams within
the study area as impaired waters for sedimentation.
No waters in the project study area are designated as North Carolina Natural or Scenic
Rivers, or as National Wild and Scenic Rivers. There are no designated anadromous fish waters
or Primary Nursery Areas (PNA) present in the study area. No benthic monitoring stations are
within 1.0 mile of the study area.
b) Jurisdictional Issues
(1) Streams
As mentioned in the previous section; six jurisdictional streams and two tributaries were
identified in the study area (see Table 12). The provisions of the Neuse River Buffer Rules apply to
all jurisdictional streams in the study area and must be adhered to during the design and construction
of this project. For the purposes of stream mitigation, all jurisdictional streams in the study area have
been designated as warm water streams.
(2) Wetlands
Twelve jurisdictional wetlands were identified in the study area. All wetlands in the
study area are located within the Neuse River Basin (USGS Hydrologic Unit 03020204).
Wetland classification and quality rating data are presented in Table 13. The locations of these
wetlands are shown on Figures 2A and 2C.
21

C) Summary of Anticipated Effects
Stream and wetland impacts have been calculated using preliminary design; therefore
impacts are calculated from slope stake limit to slope stake limit, plus an additional 25 -foot
buffer offset from the slope stakes. Stream impacts are rounded up to the nearest foot; wetland
impacts are rounded up to the nearest tenth of an acre. The anticipated impacts for streams and
wetlands are given in Tables 12 and 13, respectively.

d) Avoidance, Minimization, and Mitigation
NCDOT has utilized an alignment which attempts to avoid and minimize impacts to ti
streams and wetlands to the greatest extent practicable. NCDOT will investigate potential onsite
stream and wetland mitigation opportunities once a final decision has been rendered with regard
to the location of the final alignment. If onsite mitigation is not feasible, mitigation will be
provided by North Carolina Department of Environment and Natural Resources Ecosystem
Enhancement Program (EEP). In accordance with the "Memorandum of Agreement among the
North Carolina Department of Transportation, and the U.S. Army Corps of Engineers,
Wilmington District" (MOA), July 22, 2003, the EEP will be requested to provide off. -site
mitigation to satisfy the federal Clean Water Act compensatory mitigation requirements for this
project.
e) Anticipated Permit Requirements
It is anticipated that the proposed action will be permitted under the United States Army
Corps of Engineers ( USACE) Nationwide Permit (NWP) 23 for an approved Categorical
Exclusion and NWP 33 permitting temporary construction, access and dewatering. The USACE
holds the final discretion regarding the permit required to authorize project construction.
In addition to the 404 permit, other required authorizations include the corresponding
Section 401 Water Quality Certification (WQC) from the North Carolina Division of Water
Resources ( NCDWR). A NCDWR Section 401 Water Quality General certification for a
