3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The project area consists entirely of NCDOT right -of -way associated with US 74/76 and the Heide Trask Drawbridge
approach span. The area is historically disturbed and large areas of the study area are regularly maintained. The project
area also extends out over the MHWM of the AIWW and includes the sandy fill slope of US 74176 down to the tidal area
and aquatic community of the AIWW. Land use in the vicinity is primarily commerical or NCDOT right -of -way, with
fragmented natural thickets between the AIWW and US 74/76.
3b. List the total estimated acreage of all existing wetlands on the property:
0.01 acres
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
N/A
3d. Explain the purpose of the proposed project:
The purpose of the proposed project is to provide a safe crossing for cyclists and pedestrians across US 74/76
(Wrightsville Avenue). The walkway is part of the Gary Shell Cross -City Trail, which is a.key piece of the City of
Wilmington's Trails and Greenways System. Its construction will help address a need for alternative transportation in the
City that is safer and more convenient for citizens.
3e. Describe the overall project in detail, including the type of equipment to be used:
Phase IIIB consists of a public walkway underneath the Heide Trask Drawbridge to provide a designated crossing for
cyclists and pedestrians across US 74/76 (Wrightsville Avenue) on the mainland side of the drawbridge in Wilmington.
The proposed walkway will be 8' wide to facillitate two -way pedestrian and /or bicycle traffic, constructed of drip- through
decking with timber support pilings. Under the existing NCDOT bridge structure, the walkway will remain 8' wide, but will
be supported by micropiles to allow sufficient clearance between the NCDOT bridge supports and the walkway supports.
The walkway begins in the northeast quadrant of the Wrightsville Avenue /Airlie Road intersection near the terminus of
Phase IIIB of the Cross City Trail. It ends in the southeast quadrant of the same intersection, near the Bridge Tender
Marina parking lot. Typical roadway and boardwalk construction equipment will be utilized, including cranes, track hoes,
back hoes, graders, dump trucks, bulldozers, and pavers.

6. Future Project Plans
6a. Is this a phased project?
® Yes ❑ No
6b. If yes, explain.
The project is Phase IIIB of a larger greenway project in the City of Wilmington (Gary Shell Cross City Trail). There will
likely be future sections of greenway constructed in the City to increase the connectivity of previous greenway paths
throughout the city and to community features, however this project will be completed as one single and complete project
with independent utility by providing safe crossing under US 74176 (Wrightsville Avenue).

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Impacts have been minimized to the greatest extent practical. The boardwalk alignment was located landward of the MHWM
wherever possible, however due to height clearances dictated by NCDOT and the ADA, the alignment was forced to its
current location. The proposed walkway was also kept entirely within NCDOT right -of -way to minimize disturbance where
feasible and minimize new impacts to coastal wetlands and waters of the US. The boardwalk was also elevated as much as
possible while still meeting NCDOT and ADA requirements, and will be constructed such that the bottom of the decking will be
a minimum of 3' above the substrate supporting the wetland.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The proposed walkway will be constructed along the alignment of the boardwalk, meaning that no equipment will be within the
AIWW or any water of the US at any time. Pilings will be installed from the structure as it is built along the alignment.
Micropilings were also used wherever practical to further minimize impacts to jurisdictional areas. Where.feasible, staging and
construction access routes will be located in upland areas throughout the corridor. Tree protection fencing, silt fencing, and
other standard Best Management Practices (BMPs) and measures will be used throughout the construction process to
minimize impacts to receiving waters and to minimize runoff from the construction site.

5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or
® Yes ❑ No
habitat?
5b. Have you checked with the USFWS concerning Endangered Species Act
❑ Yes ® No
impacts?
E:1 Raleigh
5c. If yes, indicate the USFWS Field Office you have contacted.
❑ Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
According to the NC Natural Heritage Program Element Occurrence Database (updated October 2014), there are two
endangered species (West Indian manatee, Atlantic sturgeon), one threatened species (American alligator) and one
proposed endangered species (northern long -eared bat) known to occur within one mile of the project area. The project is
not likely to impact American alligator, West Indian manatee, or Atlantic sturgeon as all species have occurences outside
of the project study area and the overall impact of the proposed project is minor. The project will stay out of the navigable
water way of the AIWW and impacts are minimized by utilizing a boardwalk path elevated above coastal wetland areas.
The Heide Trask Drawbridge does have potentially suitable habitat for the Northern long- eared -bat. However, the project
is not intended to impact the bridge in anyway. A biological conclusion of 'No Effect" was determined for each species.
The "No Effect" call is due to the lack of suitable habitat or the extremely minor impact of what marginal habitat is present.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat?
® Yes ❑ No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
The NOAA Essential Fish Habitat Mapper was reviewed on December 15, 2014. Essential fish habitat was found within
the vicinity of the project study area for bonnethead shark, Atlantic sharpnose shark,. blacktip shark, smooth dogfish, and the
snapper /grouper complex. The range of these fish species is widespread in and around the coastal area of Wilmington. The
proposed boardwalk construction will have minimal impact along the edge of the Intracoastal Waterway and is unlikely to
impact the above - listed fish species.
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, federal or tribal
governments have designated as having historic or cultural preservation
® Yes ❑ No
status (e.g., National Historic Trust designation or properties significant in
North Carolina history and archaeology)?
7b. What data sources did you use to determine whether your site would impact historic or archeological resources?
The State Historic Preservation Office (SHPO) database was reviewed on December 15, 2014 to determine if any historic
resources occurred in the vicinity of the study area. There is one historically significant strucure that has been determined
elegible for National Register of Historic Places (NHRP) crossing through the project boundary . (NH3471 - Heide Trask
Memorial Bridge). However, SHPO determined that there would be no effect on historic resources during a meeting on
April 14, 2014. There are three national register individual listings and one study list individual entry (now gone) within
one mile of the study area. The project will consist of a multi -use path that crosses under the Heide Trask Drawbridge
within a currently maintained right -of -way and will not impact any historic or archaeological resource.

8. Flood Zone Designation (Corps Requirement)
8a. Will this project occur in a FEMA - designated 100 -year floodplain?
® Yes ❑ No
8b. If yes, explain how project meets FEMA requirements: The project will be located within the coastal high hazard zone and
will have no impact to base flood elevations.
8c. What source(s) did you use to make the floodplain determination? FEMA FIRM Panel 3720315700J
