James,

I apologize for the late response. We were gathering the additional information to your question below. Per the project engineer: Shifting Preston Trace, the road in question, further
east to avoid Impact C (i.e. feature F and the linear wetland) is not feasible for a few reasons. Shifting the road east to completely clear feature F and the linear wetland would shift
the bulb of the cul-de-sac to the middle of the only septic suitable soils space/lot for Lot 54 (see sheet Impact C Justification Exhibit). There is not any additional available space
with suitable soils within the project boundaries or offsite to provide septic service to lot 54 if we lose that dedicated space/lot (see sheet C-20). Additionally shifting the road
east would necessitate moving the large stormwater basin currently at the corner of lot 56 to the west side of the road (see sheet C-29 Partial Grading IX-C-29). Pushing the stormwater
basin any further east isn't feasible due to Town of Pittsboro park/open space commitments and offsite septic lot access requirements. The option of moving the pond to the west side
of the road significantly complicates stormwater management design for this area due to the topography and the need to preserve the downstream sections of streams F and F2. By shifting
the stormwater pond to the west side of the road, feature F2 would need to be crossed, the feature that runs parallel to Preston Trace (along the front of Lot 50) with a pipe/ditch to
pick up the stormwater runoff. This option is impractical and adds additional stream impacts which we were trying to avoid. In other words, relocating the stormwater basin does not
allow runoff to enter the stormwater system from the upstream lots because the basin would need to be located upgradient from the surrounding area. The topography dips down through
a low spot near feature F2 and then goes back up into upland areas. It would be difficult or impractical to get water upgradient and into the relocated stormwater basin for treatment
(the grades just don't work to get water in and then discharge it in a safe way). If the runoff cannot be directed into the stormwater basin for treatment, it would then have to "bypass"
the stormwater system. Additional runoff bypassing the stormwater basin would not comply with NCDEQ and Town of Pittsboro Stormwater regulations that dictate treatment for the 1st inch
of runoff AND control peak flow rates for the 1-year design storm.

Please let me know if this information will suffice.

Thank you,

Camden,

Thank you for the updated information. I am still struggling with the proposed impacts at Impact area C. Could you please provide further explanation as to why the road cannot be shifted
further east to avoid impacts to that system all together, as it appears there is ample uplands to do so.

Good afternoon James,

I hope you had a good weekend. In regards to your previous email requesting additional information, please see our responses below:

1. Impact area C has been minimized further with a shift of roadway design, please see attached revised impact maps as well as updated PCN above.
2. I believe Zak Shipman has taken care of this issue and provided you with a response. I have attached email correspondence above.

Please let me know if this information will suffice.

Thank you,

Camden,

After review of the above referenced PCN received on 6-3-22, it has been considered incomplete. Please address the below items so that we may be able to continue our review of the proposed
activity/PCN:

1. Under general condition 23a. Mitigation, the activity must be designed and constructed to avoid and minimize adverse effects, both temporary and permanent, to waters of the United
States to the maximum extent practicable at the project site (i.e., on site). After review of the proposed plans it appears that further avoidance of waters of the US could occur, specifically
at impact area C (Streams F and F2) by located the proposed road/cul-de-sac further east. Please provide further justification for this proposed impacts in this location or revised
plans demonstrating further avoidance and minimization.

2. On May 27, 2022 it came to our attention through an NOV from the town of Pittsboro that unauthorized activities may have occurred on the site through mechanized land clearing within
jurisdictional areas without a permit verification. (number 4 on the attached NOV). To date this has been unresolved. Please verify that no unauthorized activities have occurred within
potential waters of the US. Until an appropriate resolution occurs either through voluntary restoration or ATF permitting or it has been verified that no unauthorized activities have
occurred, your PCN will not be processed.

Please let me know if you have any questions or concerns regarding any of the above.
