RE: Riparian Buffer Authorization Request Updated Submittal (DWQ Project # 2009-0613)
Laurel Bluffs Phase 2 Trail (MST)
Eno River State Park
Dear Ms. Karoly:
Per email correspondence with Amy Chapman of your office received on 9/10/09 and 9/28/09 (attached), please find two
copies of our revised PCN Buffer Impacts table sheet and revised impact site plan maps (Sheets 1, 5-8 from the previous
PCN submittal) for the above-referenced project. These revisions reflect the relocation of significant portions of the
proposed trail alignment outside of FEMA floodzones per consultations with the Orange County Floodplain
Administrator. Your office has already received the complete application package we previously submitted and issued the
Division of Parks and Recreation a Neuse Buffer Authorization Certificate dated July 17, 2009.
The proposed project involves construction of a natural surface hiking trail in the eastern portion of Eno River State Park
in Durham and Orange Counties, NC. The proposed trail will span no greater than 6 feet in width, extend approximately
2.5 miles, and will be designated as part of the Mountains-To-Sea trail system.
The amount of Zone 1 impacts to the wooded riparian buffer adjacent to the Eno River that may be impacted by trail
construction since our most recent submission have been reduced from approximately 7,512 ft2 to 7,205 ft2 (307 ft2 net
reduction) while Zone 2 impacts have been reduced from 25,628 ft2 to 21,370 ft2 (4,258 ft2 net reduction). Significant
portions of the initial trail alignment have been relocated outside of the 50' riparian buffer to reduce impacts. However,
proposed impacts to the riparian buffer are necessary due to topographic constraints, adjoining property encroachment,
and recreational opportunity for park visitors to experience the Eno River riparian environment.
Please contact me if you require additional information.
Sincerely,
hL"Q?O ?

For the areas that are not covered under the previous buffer authorization, you would
need to wait for the revised approval from us (after we've received the revised permit app
info).
It should not take more than 20-30 days total for you to hear back from us once we
receive the application.

AMY,
Thank you for your reply. Can we proceed with trail work in these re-routed areas,
or do we need to hold off for DWQ approval of our modified Buffer Authorization? If so,
what would be the anticipated review time once DWQ receives a complete buffer
submission package?

Thanks Amin.
You'll need to submit a revised application and get a modified buffer authorization from
DWQ if any impacts to the buffer have changed. You won't have to redo the entire
application, just the buffer impact table sheet of the PCN form, include a cover letter
stating the changes, a plan sheet showing the new impacts and be sure to include the DWQ
# on the submitted information.
Thanks.

Morning Amin.
We can't accept email copies of your application as the official submittal. However, you can email me a pdf copy so I can
put that in our scanned database of permits (saves us a step) and submit two hardcopies.
Please let me know if you have any further questions.
Thanks.

If project will impact a protected riparian buffer, then complete the chart below. If yes, then individually list all buffer impacts
below. If an impacts require mitigation, then you MUST fill out Section D of this form.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Significant portions of initial trail alignment have been moved outside of the 50' riparian buffer and FEMA floodplain, trail width
is minimized, and trail surface will consist of existing natural material to avoid the addition of impervious surfaces.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Significant portions of trail alignment sited in existing foot paths. Trail surface will consist of existing natural material to avoid
the addition of impervious surfaces. Vegetation clearing will be minimal and done using hand tools. Stream crossings/bridges
will be constructed in upland areas to avoid impacts to jurisdictional waters. Appropriate measures to minimize sediment and
erosion will be implemented.

2a. Does the project require Compensatory Mitigation for ? Yes ® No
impacts to Waters of the U.S. or Waters of the State?
