Kaylie,
I have a few more questions for clarification.
Figure 3.3 shows coir matting and vegetation to stabilize the streambanks impacted by the proposed utility
crossing. Figure 3.4 shows rip rap and filter fabric on the streambanks impacted by the proposed utility crossing. Please
clarify which method will be utilized at the proposed water line crossing. If feasible, DWR would prefer to see coir matting
and vegetation per Figure 3.3.
You stated that "the seed mix will be the same as the mix approved per the site's erosion and sediment control
plan". Can you please provide the specifications for this mix that will be used in impacted areas adjacent to streams and
wetlands? DWR would prefer to see riparian areas stabilized per section 6.24 "Riparian Area Seeding" from the North
Carolina Erosion and Sediment Control Planning and Design Manual (See link below)

Subject: FW: Additional Information Request - Maple Trace - Buncombe County - DWR 15-0839
Zan and Tasha,
Please reference the Additional Information Request regarding Maple Trace and the following the responses:
1. Please provide additional information on how the proposed water line and culvert installations will occur in
accordance with Condition 6 of Water Quality Certification No. 3884 and 3890 (Work in the Dry). Please provide
the proposed construction sequence and any applicable details (e.g. cofferdams or other diversion structures) to
ensure compliance with this condition. [15A NCAC 02H .0506(b)(2) & (b)(3)]
Please reference the attached Impact Drawings — Figure 3.5, Coffer Darn Detail.
2. Please provide the proposed permanent and temporary seed mix to be used in impacted areas adjacent to
streams and wetlands. [15A NCAC 02H .0506(b)(2) & (c)(2)]
The seed mix will be the same as the mix approved per the site's erosion and sediment control plan.
3. Please update the site plan to include the most recent jurisdictional determination approved by the Army Corps
of Engineers. [15A NCAC 02H .0502(b)]
We are currently working on obtaining an overall site plan (Attachment A in the application) that reflects current
jurisdictional information. However, the updated wetland data has been added to Impact Map (Figure 3.1).
Additional questions that were presented during the JD site walk are addressed below:
1. Will there be any upgrades to the bridge crossing Reem's Creek?
Yes, NCDOT will be widening the existing bridge as a separate project.
2. What is the slope on the proposed culvert at the stream crossing?
The slope on the culvert is 10.43% which matches the existing grades.
3. Will there be any clearing within the trout buffer (other than where impacts are proposed)?
None is proposed by the owner.
4. Will culverts on site be HDPE or RCP?
The piping will all be HDPE. The headwalls will be precast concrete.
5. Is the proposed stream crossing in the same location as the existing log crossing (the log crossing is labeled as a
culvert on our delineation maps)?
The proposed strearn crossing is located at the existing log/culver location.
Tasha: Attached is an updated Stream and Wetland Delineation Map (Figure 7) that includes an additional wetland
(Wetland 9) that was identified during the site visit.
Zan: I will forward you the updated overall site plan once we receive this information.
Please contact me if you have any questions or concerns.
Thanks,
Kaylie Yankura
