4h. Explain the purpose of the proposed project:*
The purposes of the project are to improve the safety and traffic capacity of the road network on the Base and improve
and connect pedestrian paths. Safety is especially a concern at the intersection of Birch Street and Holcomb Boulevard,
and a new access road was recommended as the best way to prevent crash incidents.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
Additional turn lanes and improvements to the receiving lanes will be built at the intersection of Birch Street and McHugh
Boulevard. New left turn lanes will be added on Birch Street at the Wallace Creek Road intersection. To the north of the
Birch Street and Holcomb Boulevard intersection, access driveways to retail buildings will be consolidated. In addition, an
access road will be built along the backside of these facilities and will extend to the north tying into Birch Street across
from the northern parking lot entrance. Additional turn lanes and adjustments to travel lines will also be constructed at this
intersection. Raised islands and pavement markings will be constructed on Birch Street between Holcomb Boulevard and
Duncan Street Concrete islands, curbing, and pavement markings will be constructed along Duncan Street between Birch
Street and Sneads Ferry Road. Ajogging trail is also proposed along the east side of Duncan Street. Heavy equipment to
be used will include typical road construction equipment such as excavators, front end loaders, dump trucks, etc.

E. Impact Justification and Mitigation u
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
A scoping meeting for this project was held on December 10, 2018. The proposed roadway design at that time would have
resulted in 800 linear feet of impact to Stream C. Discussions with Brad Shaver (US Army Corps of Engineers), Robb Mairs
(NC Division of Water Quality), and Tim Lowe (Roadway Engineer at DAVENPORT) resulted in a change in roadway design
that brought the proposed impacts to Stream C to their current level of 335 linear feet. In order to accommodate this new
roadway design, engineers incorporated retaining walls and guardrails to help minimize impacts to the stream. Project
managers also coordinated with Marine Corps Base Camp Lejeune Public Works concerning the future relocation of a Sub -
Station just north of the project area as well as the existing overhead power lines under which the newaccess road would
cross. This coordination with Public Works permitted the current design in which the new access road is placed on the
northern side of Stream C, minimizing impacts.
The sediment and erosion control plans for culvert outlet and inlet protection call for riprap to be buried in the streambed so as
to not cause a loss in stream channel.
The demolition plans call for the removal of a sluice gate that was installed within Stream C. The installation of this sluice gate
effectively and functionally divided Stream C into two different stream segments and likely acted as a barrier to the
movements of aquatic organisms. Removing the sluice gate will restore the stream back to more natural conditions.
Fill slope ratios were designed at a 3:1 ratio in order to minimize disturbances to streams and wetlands.
For Impact Numbers S1 through S3, note that the current stream channel (Stream A) is not aligned with the proposed 60"
RCP and the proposed culvert opening is approximately 5 feet east of the current stream channel. The reason for this
misalignment is that the proposed 60" RCP is an extension of an existing 60" RCP that continues under Birch Street. A
complete replacement of the existing 60" RCP is unfeasible due to the cost of replacement and the need to completely close
down Birch Street, a major thoroughfare in the Marine Base, in order to replace the existing RCP. The impacts to Stream A
include re -grading to direct the stream to the proposed headwall, riprap placed in the stream channel for inlet protection, and
the extension of the 60" RCP.
At Site 4, the proposed access road crosses the stream at an angle less than 75 degrees. A crossing at a higher degree was
not possible due to the presence of the overhead electric power lines and supporting poles in this area. The road was thus
designed to parallel these lines.
There are two road crossing proposed for Stream C (see both Site 4 and Site 5). One purpose of this project is to improve the
safety of the Birch Street and Holcomb Boulevard. Currently, this intersection has many curb -cuts and conflict points that can
be reduced by the construction of the newaccess road behind the commercial buildings. This new access road is designed to
ease circulation among the existing businesses, but this can only be accomplished if there are two crossings of Stream C.
These crossings were designed to be as far apart as possible from each other in order to minimize the cumulative impact on
the stream.
The outlet protection riprap for Sites 4 and 5 will impact 48 and 39 linear feet of stream, respectively. Calculations for the
amount of riprap needed are provided in Plan Sheet CC503 included in the Impact Figures. This large amount of riprap was
needed because of the high maximum flowvelocities estimated for this stream. To reduce impacts, the riprap will be buried in
the stream channel and set flush with the stream bottom.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Sediment and erosion control Best Management Practices (BMPs) have been developed specifically for this project. Silt
fences will be used on stream banks in order to prevent sedimentation into the stream. In addition, a silt fence will be installed
around the entire project area to further minimize sedimentation. Silt fences and other sediment and erosion control devices
will be removed after completion of each phase.
The construction of the project will be phased in order to limit the amount of time that streams and wetlands will undergo
temporary impacts.
Construction of the culverts will be done 'in the dry' when feasible in order to minimize impacts.
Tree and vegetation clearing will be minimized to the greatest extent possible. Precautions will be taken not to disturb root
mats outside the project area. Construction equipment will not be staged on wetlands or near streams.

3c. Comments
The permanent impacts to the channel of Stream A total 28 feet. We propose to mitigate impacts to Stream A
at a 2:1 ratio, for a total of 56 credits. The permanent impacts to the channel of Stream C total 248 feet. We propose to
mitigate impacts to Stream C as a 1.5:1 ratio for a total of 372 credits. Altogether, the total number of credits is 428.
Stream A was rated as Medium using the NC Stream Assessment Method (see attached forms and photos).
Stream C was rated at the two locations in which impacts are anticipated: Site 4 and Site 5. Both Sites received a score of
Low using the NC Stream Assessment Method (see attached forms and photos). Stream C is located in a heavily commercial
area of the Base and has been impacted by historic and current land use. These impacts include the installation of a sluice
gate and riprap within the stream in order to control flow. Upstream of the sluice gate, Stream C is very sluggish and flow
rates are minimal, resulting in a more of a lentic environment with emergent vegetation such as cattails. Downstream of the
gate, Stream C is very incised, likely a result of high storm events released with the opening of the sluice gate. In the impact
area, the top of stream bank is extremely narrow and ranges from 0.5 feet to 1.5 feet. This area also lies under two electrical
power lines. The maintenance of vegetation under these lines has resulted in a lack of shade in this reach of Stream C.
The proposed project will remove the sluice gate, which would help restore the stream's natural flow regime.
6. Buffer mitigation (State Regulated Riparian Buffer Rules) - required by DWR
6a. Will the project result in an impact within a protected riparian buffer that requires buffer mitigation? If yes, you must fill out this entire form - please contact DWR for more

rules.
2. Stormwater Management Plan
2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250?*
r Yes r No
Comments:
Drainage from the linear roadway improvements is anticipated to primarily follow the eAsting drainage patterns which
guide the runoff to proposed swales with 3:1 side slopes and eAsting major drainage ways for treatment. There are
several eAsting permit areas that require modification to maintain the approved Built -Upon Area (BUA), which will be
achieved by removing impervious area from the permit area and adding equal impervious areas resulting from the
proposed project. If there is a resulting increase of impervious area to the permit boundary, the increase in impervious
area requires treatment for the 1.5-inch rainfall event prior to discharge to the eAsting stream conveyance stream.
The new access road at the Sites 4 and 5 Will require modifying the eAsting permit. Part of the access road will be located
down the center of the wasting permit, thus adding impervious area to the wasting BMP. A portion of existing impervious
area greater than what is being added will be re-routed away from the eAsting BMP and treated within the expanded
permit boundary by incorporating a new sand filter BMP. This separately treated bypassed area will be conveyed to the
eAsting stream via new underground draw down pipe and armored spillway.
The Exchange/Commissary, Wendy's/Taco Bell, and Marine Federal Credit Union (MCU) permits are proposed to be
merged. The MCU parking lot, which currently is not permitted will require treatment of the 1.5-inch storm event. The MCU
parking lot, along with part of the access road connected to the service runoff will be treated with a new sand filter BMP.
This new BMP will be conveyed to the wasting stream via new outlet control structure and underground piping.
The drainage for the Birch Street and Wallace Creek Road improvements are based on low density linear project
requirements. The proposed increase in BUA has been included in the permit modification for this area, with runoff
directed to roadside swales with side slopes at 3:1.
