Re: Charleston Village Greenway Connector - Riparian Buffer Authorization Request
Apex, Wake County
WR # 02170815.00
Dear Mr. Ms. Higgins,
On behalf of the Town of Apex, we are requesting Buffer Compliance from the NCDWR for 2,659
sq ft of permanent impacts to Jordan Lake Riparian Buffers for construction of the Charleston
Village Greenway Connector project.
The project area is located between the Charleston Village Subdivision (Castleburg Drive) and
Sutton Place Subdivision (Hill Hollow Way) in Apex (35.762683°N; -78.864486°W). The prposed
greenway connector will cross a UTto Beaver Creek. The project is located in the Cape Fear/Jordan
basin and onsite waters drain to Beaver Creek. The Water Quality Classification for Beaver Creek
is WS -IV; NSW and the Stream Index Number is: 16-41-10-(0.3). The cataloging unit for the site is
03030002.
Proposed Project
The proposed project consists of construction of a greenway trail connector that will connect the
Charleston Village greenway and Sutton Place greenway. Both greenways currently terminate on
opposite sides of the stream. The proposed connector will provide a connection between the two
greenways, allowing pedestrian and bike traffic to access both greenways, thereby expanding the
greenway network.
The greenway connector has been designed to utilize an elevated boardwalk to cross the stream to
avoid stream impacts entirely.
Project History
WithersRavenel conducted a wetland delineation for the proposed greenway connector alignment
in December 2017. The delineation determined that there are no wetlands within the alignment,
and the only jurisdictional feature is a buffered stream. Since the stream crossing will consist of an
elevated boardwalk, thereby avoiding stream impacts, a formal Jurisdictional Determination is not
required as there are no proposed impacts to jurisdictional features.

Our People. Your Success.
Additionally, a formal buffer determination from NCDWR is not required as subjectivity to riparian
buffers is obvious and conceded.
Proposed Impacts
The proposed impacts consist of 2,659 sq ft of permanent impacts to riparian buffers (Zone 1:1,527
sq ft; Zone 2: 1,132 sq ft) for the construction of the greenway connector.
Avoidance and Minimization
The proposed greenway connector has been designed to cross the riparian buffers at a
perpendicular angle to minimize impacts to buffers. Also, the actual stream crossing will be bridged
to avoid impacts to the stream.
Mitigation
Greenway trails are classified as "Allowable" and do not require mitigation.
The current request is for 2,659 sq ft of permanent impacts to riparian buffers (see the attached
maps and PCN for details).
Please feel free to call if you have questions or require additional information.
Sincerely
WithersRavenel

Senior Environmental Scientist
