Dear Ms. Euliss:
On behalf of the City of Greensboro, the following is provided in response to your letter dated
August 12, 2010 regarding the proposed Ballinger Road Bridge Replacement project. A brief
summary of the comments contained in your correspondence on behalf of the Division of Water
Quality, Transportation Permitting Unit are summarized below, along with the corresponding
responses.
Comment: For the purposes of the Table of Uses in the Jordan Buffer Rules, the bridge
crossing is considered a crossing only within the area between the end bents, all other
impacts to Horsepen Creek and the UT are considered parallel impacts. Please delineate
parallel buffer impacts to Horsepen Creek and the UT to Horsepen Creek (Stream A) for
roadway approaches separately on your permit drawings, and provide approval of
associated mitigation for the parallel impacts.
Response: The plan depicting the parallel buffer impacts to Horsepen Creek and Stream A
resulting from roadway approaches is included as Attachment A - Figure 9 (revised). Parallel
impacts resulting from roadway approaches totaling 2,553 sq. ft. in Zone 1 and 4,280 sq. ft.
in Zone 2 will be mitigated by the purchase of 7,659 sq. ft. of Buffer I and 6,420 sq. ft. of
Buffer 11 riparian buffer credits from the North Carolina Ecosystem Enhancement Program
(NCEEP). Approval for the purchase of these riparian buffer credits, as well as the stream
mitigation credits is included as Attachment B.
Comment: Fill out the buffer impact table, separating out the impacts from the roadway
approaches, bridge, walking trail (separate from sidewalk), and utility impacts.
Response: A buffer impact table separating out the impacts from the roadway approaches,
bridge, walking trail, and utility impacts is included as Attachment C - Buffer Impact Table.

Comment: Show the walking trail on plans and associated buffer impacts that are
beyond those impacts necessary for the bridge/road.
Response: The walking trail buffer impacts have been separated from the bridge/roadway
and utility impacts and are depicted on Attachment A - Figure 9 (revised).
Comment: Explain why fill slopes cannot be further reduced to 1.5:1 to further avoid
parallel buffer impacts.
Response: According to Shannon Leonard in the Winston Salem office of NCDENR
Land Quality Section, NCDENR will not approve roadway slopes steeper than 2:1 for the
Ballinger Road Bridge Replacement Project. A revised roadway and bridge plan that
utilizes a 2:1 slope has been prepared for the project and has reduced parallel impacts
to the buffers, as well as direct impacts to Stream A. Impacts to Stream A have been
reduced from 94 linear feet of permanent impact (763 sq. ft.) to 87 linear feet of impact
(725 sq. ft.). The revised roadway and bridge plan is included as Attachment D - Figure
6 (revised).
Comment: Provide a plan and profile for the relocated stream. Although this is not a
natural channel design, the Division needs enough detail to ensure the proper
dimensions will be constructed and that grade controls are included if necessary.
Response: The plan and profile for the relocated stream is included as Attachment E -
Figure 11).
Comment: Show a proposal for shifting road to the other side, including an overlay of
impacts to the mitigation site.
Response: The City of Greensboro cannot shift the roadway to the other side due to the
FedEx mitigation site located on the south side of Ballinger Road. Please see the
attached PTAA Airport Development Plan that depicts the various PTAA mitigation sites
as green cross-hatching, and the Ballinger Road Bridge Replacement Project site as a
red dot surrounded by orange highlight (Attachment F - PTAA Airport Development
Plan).
Comment: Include NCDOT as the owner of the road, if they currently and will continue
to own the road.
Response: The City of Greensboro is the owner of the road, has been the owner of the
road, and provides the maintenance for the bridge and roadway.

This letter replaces one issued July 26, 2010. The purpose of this letter is to notify you that the North Carolina Ecosystem
Enhancement Program (NCEEP) is willing to accept payment for impacts associated with the above referenced project. Please note
that this decision does not assure that the payment will be approved by the permit issuing agencies as mitigation for project impacts. It
a ,
is the responsibility of the applicant to contact these agencies to determine if payment to the NCEEP will be approved. You,museal'so
This acceptance is valid for nine months from the date of this letter and is not transferable. If we have not received a copy of the
issued 404 Permit/401 Certification/CAMA permit within this time frame, this acceptance will expire. It is the applicant's
responsibility to send copies of the permits to NCEEP. Once NCEEP receives a copy of the permit(s) an invoice will be issued based
on the required mitigation in that permit and payment must be made prior to conducting the authorized work. The amount of the In
Lieu Fee to be paid to NCEEP by an applicant is calculated based upon the Fee Schedule and policies listed at www.nceep.net.
Based on the information supplied by you the impacts that may require compensatory mitigation are summarized in the following
table.

Upon receipt of payment, EEP will take responsibility for providing the compensatory mitigation. If the regulatory agencies require
mitigation credits greater than indicated above, and the applicant wants NCEEP to, be responsible for the additional mitigation, the
applicant will need to submit a mitigation request to NCEEP for approval prior to permit issuance. The mitigation will be performed
in accordance with the N.C. Department of Environment and Natural Resources' Ecosystem Enhancement Program In-Lieu Fee
Instrument dated July 28, 2010.
