Gonzalez Boulevard Extension (P1265)
B. Project Information and Prior Project History
3d. Explain the purpose of the proposed project.
A permanent incremental increase of Marine Corps personnel is currently underway at Marine Corps
Base (MCB) Camp Lejeune (Base) under the Grow the Force initiative. A force addition of
approximately 7,000 marines is proposed at the Base. To support this growth, the USMC proposes a
combination of: (1) new infrastructure construction (e.g. buildings, roads, utility lines/equipment); (2)
demolition and/or upgrades to existing infrastructure; and (3) relocating existing units and personnel to
consolidate and better support combat missions. These expansions are to address current
deficiencies as well as in support of new facilities that are proposed for construction under Base
expansion as documented in the Final Environmental Impact Statement (EIS) USMC Grow the Force
in North Carolina (December 2009). At the Base, the USMC proposes to extend Gonzalez Boulevard
from its current terminus at McHugh Boulevard, to the French Creek Bachelors Enlisted Quarters
(BEQ) that is already under construction. The extension will provide additional access to the BEQ
from McHugh Blvd.
Gonzalez Boulevard Extension
This project consists of the extension of Gonzalez Boulevard from the current tee intersection of
McHugh Boulevard and Gonzalez Boulevard to the intersection of Birch Street and Gonzalez
Boulevard. Birch Street and the eastern leg of Gonzalez Boulevard are currently under construction
as part of the French Creek BEQ. An 877 ft bridge is proposed to avoid impacts to the wetlands. The
total project length is approximately 3,600 LF. The proposed typical section is a 2-lane roadway with
shoulders and roadside ditches/swales. Pedestrian access is provided on one side of the road. The
bridge section will have walkways with a barrier to separate the roadway from pedestrian traffic. The
roadway shall have LED streetlights included in the design package. This roadway intersects with an
existing tank trail. The design will include relocation of the tank trail to pass under the bridge.
3e. Describe the project in detail, including type of equipment to be used.
The total bridge length is 877 ft consisting of eleven 67 ft interior spans and two 70 ft end spans. The
proposed typical section consists of two 12 ft wide traffic lanes, two 3 ft wide shoulders, and an eight
foot wide pedestrian lane separated from the roadway with a barrier. The total bridge width including
interior/exterior barriers is 43 feet. Utilities supported on the underside of the bridge deck include a 14
inch diameter closed drainage line that will run along the right (low) side of the bridge and connect to a
drain inlet at the end of bridge; and 9- 5 in. diameter conduit runs to be placed below the greenway
trail and between interior girder no. 4 and exterior girder no. 5. The conduits will be accessible
through an access hatch and stainless steel pull-box located in the greenway trail path on the bridge.
Light poles will be provided at 135 ft spacing's along the bridge and will be supported on the outside of
the bridge deck adjacent to the greenway trail. Bridge components and layouts, such as girder type,
spacing, span length, and substructure type were chosen based on constructability, economy, low
maintenance, sustainability and longevity.
The bridge will be supported on driven 2 ft square concrete piles. At each bent 7 piles will be driven.
Ten bents are located in the wetlands. A temporary work bridge will be constructed on the northwest
side of the bridge to facilitate driving of piles and bridge construction.
AECOM
The tank trail will be relocated to pass under the bridge at a location where horizontal clearance (50 ft
min.) and vertical clearance (16.0 ft recommended) requirements are satisfied. The bridge
substructure will be protected with a deflective concrete bollard system developed for this site. The
concrete bollards will be 3ft in diameter, strategically positioned and designed to help deflect the tank
impact energy and deter the tank driver from proceeding any further off the trail if a bollard should be
struck. The bollards will also be painted with a reflective yellow paint. Reflective delineators will be
placed along each side of the tank trail and to help guide the tank driver through the underpass and
raise awareness of the curve in the tank trail and the approach to the overpass.
The roadway and tank trail will be constructed using standard roadway construction equipment such
as bulldozers, road graders, and dump trucks.
4. Jurisdictional Determination
The wetlands were delineated by Tetra Tech in 2010. The wetland boundary was surveyed by
Charles F. Riggs and Associates and a jurisdictional package was submitted to the US Army Corps of
Engineers. A Jurisdictional Determination was issued by the USACE on March 24, 2011 (Action Id.
SAW-2010-01798).
6. Future Project Plans
Several projects associated with Grow the Force are occurring in the Cogdels Creek watershed and in
the immediate vicinity of each other. These projects include the installation of sanitary sewer gravity
mains, water lines, and the construction of a tank trail. Because all these projects have an
independent utility, separate 404 permit applications are being submitted for the projects. The
sanitary sewer gravity mains are part of a project titled Hadnot Point-French Creek Utilities that are
being covered under a Nationwide 12 application. Wetland impacts associated with the utility project
include 0.4 acres of permanent impacts and 1.0 acres of temporary impacts.
The tank trail projects consist of construction of a tank trail across the Cogdels Creek and associated
wetlands. Wetland impacts associated with this project are approximately 1.0 to 0.9 acres of
permanent impacts and 0.4 acres of temporary impacts.
C. Proposed Impacts Inventory
2. Wetland Impacts
2h. Comments
Wetland impacts include 0.30 acres of wetlands that will be filled and temporary impacts to an
additional 2.12 acres of wetlands that will be hand cleared to allow for construction of the roadway and
bridge. Proposed construction limits were used to determine temporary impacts and not all areas
shown may be cleared.
At Wetland Site No. 2 wetland impacts associated with the installation of a force main and a gravity
main along the west side of the road have been accounted for in the Hadnot Point-French Creek
Utilities PCN submittal. These impacts include 0.05 acres of permanent impacts from the clearing and
maintenance of a permanent utility right-of-way and 0.05 acres of temporary hand clearing of wetlands
to facilitate construction and installation of the utilities.

D. Impact justification and Mitigation
1.a Specifically describe measures taken to avoid or minimize the proposed impacts in
designing project.
Gonzalez Boulevard Extension crosses an extensive wetland area. The entire wetland will be
bridged, virtually eliminating impacts to the wetland. Additionally, all stormwater from the bridge will
be collected in a closed drainage system and discharged into stormwater treatment BMPs in upland
areas at each end of the bridge. No stormwater will be discharged into the wetland from the bridge.
The bridge was aligned to cross the wetlands as perpendicular as possible.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through
construction techniques.
Bridge construction is to occur by use of a temporary work bridge adjacent to the proposed bridge.
The work bridge will be constructed on piles using top-down construction. Wetlands beneath the
bridge and work bridge will be hand cleared. No mechanized clearing will occur except at pile
locations if required. Therefore, the impacts from construction will be temporary and the wetland
areas will be allowed to revegetate following removal of the work bridge when bridge construction is
complete.
As part of a separate project a gravity sewer line is to be installed across the wetlands. The sewer
line has been placed as close to the bridge as practicable. Additionally, the proposed work bridge has
been located in the same footprint of the sewer line to minimize the area needed for clearing.
E. Stormwater Management and Diffuse Flow Plan
A stormwater management plan is currently under preparation and will be submitted to the NC
Division of Water Quality for their approval.

While several Endangered Species are known to occur at Camp Lejeune, suitable habitat for those
species are not present in the project area. Extensive surveys for various federally-listed species
have occurred on the Base. The Base GIS data did not indicate any know occurrences of any
threatened or endangered species in or near the various utility corridors. Surveys of these areas by
AECOM biologists did not reveal any suitable habitat for any species.
